【 Weak current College 】 Pudong International Airport T2 terminal of building automation system flight linkage

1 background information
With the external economic situation is increasingly grim, enterprises face significant pressures running efficiency. Enterprises must adjust the operation and management mode, enhance the energy efficiency of new technology, promote energy-saving work.
Pudong airport second phase construction into the construction of the concept of Green Airport, across the project phase II project has adopted a number of advanced energy-saving measures, such as the building envelope, side window natural air ventilation system, paddock River, rainwater reuse peak water thermal storage HVAC engineering, secondary water conversion systems, air-conditioner units, etc. In these efficiency significantly on the basis of the equipment and facilities, the new T2 terminal of building automation system is run from the system device management perspectives highlighted on the Department of building science system for energy management.
Generally speaking, the core system of the operation of the airport is the airport information integration system, and terminal equipment facilities management core system is building automatic control system, hereinafter referred to as BA system. Terminal building has a large air conditioning systems, lighting systems, as well as many different functions and relatively independent subsystems, such as side window control system, UPS power monitoring system, air source heat pump control, multiple online air conditioning networking control, aircraft chlorination system, living water monitoring, etc., these facilities and their full integration in the subsystem BA systems management platform. Therefore on BA systems advanced migration control management can greatly improve the building's overall management level.
Improve the management level of BA system is mainly reflected in the regulated facilities and subsystem to work, while reducing its energy consumption, T1 terminal only water, gas, the annual cost of over 2 billion, is now operational in T2 terminal area nearly doubled, enterprises running cost pressure is very great, efficient on BA systems, scientific management can dramatically improve the building's running costs.
　　
2 objectives
Typically, the airport of BA system on its main monitoring equipment: air conditioning systems and lighting system of control by regulation of the air conditioning unit medium water flow to control the air conditioning unit for supply air temperature, so as to achieve the control of the public area of the scene temperature; while leveraging the scene illumination threshold than the set value to control the lighting system of the switch. On this basis, the Pudong airport T1 terminal operator according to the flight plan, manual setting air conditioning and lighting system on the day of the last flight of the day after the closing time and the first flight on time.
As an airport building area of large, artificial set start and stop time mode cannot be set dynamically adjust the time, and will not be able to adapt to the managed regional subdivision of management requirements as far as possible, over the years all domestic airport's Terminal Building Management Department has been actively exploring use of flight information-automatic real-time linkage control BA system, in order to successfully complete this difficult job objectives, well-defined new Pudong airport T2 terminal building automatic control system of several late debugging:
◆ Composition system combined with debug Panel, composed of multiple departments and branch offices work together to make the system meet advance planning objectives;
◆ Ensure that BA system of the front-end device is working correctly, the sound system the main platform features, and ensure the normal operation of the relevant subsystem it belongs;
◆ Take the lead by transportation management units, on-site control of the various control regional needs to be clear, the formation of written documents record;
◆ The subregional programme for further refinement of the flight, and gradually make the linkage between its programmes, software interface for operability and controllability and stability;
◆ On an initial assessment of the project implementation, the use of energy, the construction investment projects as soon as possible to achieve cost recovery.

3. programme implementation
Terminal of the promenade and the main building as well as the connection Gallery passenger operations characteristics, route flows, residence time and resident units of work are not all the same, so you will need to find an individual partition of air conditioning and lighting systems with different operating rules, and find a matching energy-saving programmes.
We put the Terminal is divided into Terminal promenade, znternational (including the main connection Gallery) to develop special linkage control programmes.
　　
3.1 Terminal promenade flight linkage control programme
(1) the overall among the divisions corridor joint programme
Airport of each flight has a corresponding boarding bridge, boarding bridge also belong promenade of A1, A2, A3, B1, B2, B3, B4, C1, C2, C3 ten partitions, partition are interlinked, the air conditioning units and lighting systems of joint control mode as follows: when a1 flight, the system will turn on A1, A2, A3, B1, B2, B3 area of air-conditioning units and lighting. When there are special A2 segment, the system will open A2, A3, B1, B2, B3 area of air-conditioning units and lighting. When there are special paragraph A3, the system will turn on A3, B1, B2, B3 area of air-conditioning units and lighting. Similarly close using reverse linkage query, promenade C segment likewise. Table 1-Regional Division for special linkage, and said that when a partition is occupied by other sections of the linkage between devices.
(2) joint action equipment and stopping rules
The integrated system for airport flight information, published by the international departure arrival flights, domestic departure arrival flights in the database is defined, the database fields in the international segment for "FlightSectorCode I" and "R", the domestic segment of FlightSectorCode "D" and "M", all integrated systems published by the international and domestic flights included REG: regular flights; RET: return flights; SLI: sliding back flights; ALT: alternate; CSF: sharing; DEL: delay; MER: merge, types of flights.
According to the above basic information, we have formulated the following managed devices and stopping rules:
◆ International and domestic reach open device control: to plan time ScheduledDateTime, expected time EstimatedDateTime and actual time WheelsdownDateTime real-timeAmendments to the scheduled time, and finally into the amount of time in advance, that reach the open initial time ArvOpenTime. Mathematical expressions are as follows:
◆ International and domestic reach closure device control: WheelsdownDateTime actual arrival time, and finally into a time delay, that reached a preliminary time ArvCloseTime turned off. Mathematical expressions are as follows:
◆ International domestic departure on the device are as follows: to plan the departure time is subject to final ScheduledDateTime again into the amount of time, come out ahead on initial time DepOpenTime. Mathematical expressions are as follows:
◆ International domestic departure control shutting down equipment as follows: in the actual departure time is subject to final WheelsUpDateTime again into the time delay, that start off initial time DepCloseTime. Mathematical expressions are as follows:
The above four math expression represented as AdvaceTime refers to both the start-up and shut-down of all the equipment you need to set a certain lead and lag time, because the air conditioning system is based on onsite space needed prefetch function in a certain period of time, in addition to on-site staff also need to enter the venue and delayed exit the site.
(3) actual control strategy
According to the second step in the commitment of linkage equipment rules calculate arrival time starting and stopping, starting and stopping the initial preliminary time, flight time calculation method to calculate the actual start and stop the scene-related equipment of control commands. Here refers to the flight clearance meant 24 hours a day for each partition of the same properties of flights before and after the two adjacent flight time interval.
Concrete is calculated as follows: table 2 flights 1, 2, 3, 4 belong to the same partition a1, international reach, according to the second step calculates the open and close after the initial time and chronological order, the adjacent flights 1 and 2 of the interval is from flight 1 close time flight 2 opening time of absolute value, and so on. Interval of mathematical expressions are as follows:
　　
Similarly, international departure level of mathematical expressions:
　　
Domestic 4.2m layer is the departure arrived Francis layer, all domestic flights with departure and arrival: calculation
　　
Because the air conditioning system of field effects need preaction, according to the actual size of the space, generally at least half an hour, interval time standards can be based on the situation and request a free set of energy-saving. When the calculated interval greater than or equal to the set time interval, the managed device to stop working, when calculated interval is less than the set interval, BA system produces non-stop command. At run time in a long corridor of the interval is set to 1 hour.
It should be noted that the various effects of irregular flights have been in the second step in the initial time and stopping equipment in the consideration, if delays flights, WheelsdownDateTime time does not appear, the managed device will not be closed; at the same time, the database automatically temporarily WheelsdownDateTime does not appear in the special reorder, does not affect the normal interval calculation.

3 znternational flight linkage control programme
Main building of special linkage control programmes in relation to relatively simple compared to the promenade. Main floor, main building, the main hall and baggage area and the main connection Gallery two parts, the control scheme is as follows:
◆ Building Suite 6m and arrive at layer i.e. baggage 0m extraction areas of linkage in accordance with the plan to open the device time ScheduledDateTime, expected time EstimatedDateTime and actual time WheelsdownDateTime real-time correction plan time plus the amount of time to determine ahead of time. At the same time, according to the baggage carousel, turntable, can be divided into A district 6m layer international (# 20 ~ # 25 turntable) and zone b (# 26 ~ # 31), A district (# 33-# 35) and zone b (# 36 ~ # 39); 0m layer international A district (# 40 and 41) and zone b (# 42 and 43), A district (# 44) and zone b (# 45), open the appropriate regional related equipment. Mixed flights have two luggage turntable, you need to simultaneously open two regional units.
◆ The arrival time of equipment off by opening time delay in General 1-2 hours (concrete transported by the Terminal control centre TOC). At the same time, close the command needed to judge this flight and the next flights Open interval, only the interval time is greater than or equal to the set value is ultimately issued close command.
◆ Building Suite ScheduledDateTime 13.6m departure level to prevail, then the amount of time, turn on the device in advance. Departure level close to the actual takeoff time WheelsupDateTime prevail, while at the same time and the next flight schedule departure time calculated interval that is greater than or equal to the set value off command is issued.
◆ Building Suite connection corridor area of departure level divided into domestic and international regions, reaching levels divided into domestic and international regions, its control similar promenade of control.

4 terminal lighting control
Terminal lighting circuit nearly 10 per cent of lighting is basic lighting load settings to prevent unforeseen events lead to public places because no light source and confusion. The other 30 per cent of the lighting is controlled by the illuminance sensor, this part of the lighting circuit automatically according to the natural light intensity control lighting and stopping. At present the illuminance sensor set to 550 ¡à 80LUX, spot lighting automatically distinguish between day and night, and rainy days, when light intensity low (less than 550LUX), supplementary lighting at any time.
In order to better carry out energy conservation work, for the remaining 60 per cent of lighting, we in the illumination control adds flight linkage control. Specific control methods like this: during the day (light intensity is greater than 630LUX) flight linkage to close at night (care degree less than 470LUX) open flight linkage, and close the light perception control, its flightLinkage control mode and the same position of the air conditioning unit flight linkage binding implemented simultaneously.
　　
5 effectiveness evaluation
5.1 system enters automatic operation, reducing monitor the intensity of work to improve the level of management
Flight linkage control interface is simple and clear, as shown in Figure 1, Figure 1 is a computer operation screenshot has clearly shown in the figure A section linking device Gallery's enabler, diagram as a1 flight occupancy, A1 segment opens the linkage, A2 and A3 segment also enabled (green).
In Figure 1 of the lower right corner there is a whole gallery of navigation diagram, you can click on the navigation chart for other regions, thus rapidly converted to other bitmap, the Navigator also shows the status of other regional linkage Gallery, Figure 1 shows that other regional flight linkage is open.
Another figure 1 also reflects the boarding bridge on the operation of the equipment; mouse moves to the boarding bridge can even appear on bridge aircraft the flight number and arrival and departure time.
Flight United system really entered the automatic intelligent health, fundamentally enables operator reduces human timesheet timing settings, reducing operator mistakes and improve system management efficiency and quality.

5.2 control more accurate and meticulous, and a substantial increase in energy-saving effect
(1) based on data acquisition
In order to more objectively assess what flight linkage, from October 2008 15: 28 to 2008-11-18, 16, use BA system multipoint tracking functions, on the promenade A, B, C paragraph 10 partition 4.2m domestic arrival departure level, 8.4m international reach, 13.6m international departure level of 47 linkage point for the analysis of trace and stopping the device, as shown in Figure 2, the linkage of 2008 during the period from 9 to 11 November promenade A segment of the air conditioning and lighting systems of switch status tracking map. On the right side of the window, three lines represent a, A1, A2, A3 section of air-conditioning units and lighting of the open-closed, for example, you can see in the figure a day at 00: 08: 30 ~ 50 air conditioning units and lighting is turned off.
(2) analysis of energy saving effect
First, we calculate Terminal promenade all participating flight linkage of air-conditioning units and lighting systems of power, air handling units includes a unit of blowers and back to fan power, lighting including the downlight, lamp, lamp, metal halide lamp pole, big space lights, etc. All devices are carried out at subregional level statistics, as shown in table 3.
Since Oct. 28, 15: 00 ~ 11/18/16: 00, after implementing flight linkage related units and lighting for a total of 20 days running 25-hour total 505 hours. Because the device is running to save time = not enforced flight linkage devices running time (505)-implementation of the actual run-time after the linkage, so according to on-site managed devices actually run time calculated in table 4 (flight after the device actually run the linkage is based from BA system database out of time tracking data set).
Finally using the formula: power = power (w) × time (hour), 1 unit = 1 kWh = 1000 Watt ×, the junction table 3 and table 4 results you can count the standing floor promenade sailing section central air conditioning and lighting system saves energy, derived from table 5. You can see a building area of 21 days of air conditioning units and lighting power saving of 626593.98 degrees, the amount of electricity a day as 29835 degrees, if projections to the year, the annual electricity output can reach 10890800 degrees about 1089 million units of electricity.
Terminal promenade in air conditioning units and lighting power 5055.2kW, 24 x 7 operation of one-year electricity consumption reached 44283552 degrees, flight after a total saving of linkage promenade, power save percentage of 10890800 as shown in Figure 3.

Comparison of traditional energy-saving 5.3 method
These statistics are compared with flight linkage conditions to participate in the joint equipment all day open condition, if contrast traditional manual setting timetable for scheduled stops, this flight linkage effects equally impressive.
Typically, the traditional manual setting unit commitment usually man-made under at the latest flight schedule set at the end of the last flight in the morning air conditioning and lighting off time, and the first flight after the start of the opening hours of the device. This first flight at the end of the day you can have the law generally 3 hours of downtime. Promenade units and lighting of total power, manual setting for 5055kW daily can save power by: 5055kW× 3 hours = 15165 degrees, a year of electricity-saving rate is about $ 554 million units of electricity. Use power-saving flight linkage, as 1089 million units of electricity, than the traditional schedule settings more saving nearly 535 million degrees.
Also note that the BA flight linkage preliminary evaluation of energy-saving work, just based on the promenade of the terminal building and the air conditioning unit of electricity consumption for lighting system, the main building and traffic center section yet, and no statistics saving of heat and cold sources of heat (this heat can be converted to energy Center unit electricity consumption), but also not including 42 boarding bridge on VRV and related lighting to save electricity.
　　
6 closing
By implementing flight linkage control, building automation system from the manual setting mode, the timetable of work truly realized fully automatic control, Pudong airport became one of the few success in China with dynamic flight linkage control terminal building automatic control system of BA.
T2 terminal building of this energy saving effect is gratifying, only terminal promenade part each year at least can economize on electricity by 10 million degrees, not including the main building and traffic centre, as well as energy centers and other related equipment in the amount of electricity-saving. Even if it is relative to the traditional cumbersome manual timer switch method, this promenade flight linkage control or at least more to conserve electricity 500 million degrees. At the same time, the flight linkage of successful implementation, improvement of the system of migration control BA platform and interface, the parties to a late work to expand to further refine the energy-saving programmes have laid a solid foundation.
This is the Pudong airport flight linkage building control system of preliminary results of the evaluation, the next step, the further perfection of T2 znternational and traffic centre of flight linkage and Pudong airport building control systems and the overall evaluation flight linkage, as flight linkage projects will eventually fell to the ground, Pudong airport, towards effective management of advanced significantly, System Advanced continues to Green Airport.
