Description

Technical Field

[0001] This utility model mainly relates to the field of air conditioning control technology, specifically to a remote control device for air conditioning on boarding bridges. Background Technology

[0002] Once connected to the airport control system, the air conditioning system and ventilation fans currently configured on the boarding bridges can be scheduled to start and stop based on information recorded in the overall flight schedule within the airport control system, such as flight number, scheduled departure time, estimated departure time, actual departure time, gate identification, scheduled arrival time, estimated arrival time, and actual arrival time.

[0003] To quickly adjust the air temperature inside the boarding bridge, it is also necessary to access temperature data from multiple temperature sensors inside and outside the boarding bridge, as well as the actual working length of the boarding bridge, to adjust the operating parameters of the air conditioning system and ventilation fan. This is to avoid the situation where the operating parameters of the air conditioning system or ventilation fan are set to fixed parameters and cannot be adjusted according to the ambient temperature requirements inside the boarding bridge, which would reduce the comfort of the environment inside the boarding bridge.

[0004] Therefore, when constructing a remote control device for the air conditioning equipment of boarding bridges, in addition to the servers, controllers, and networking equipment already configured at the airport, multiple temperature sensors need to be configured on the traditional boarding bridge equipment according to design requirements. A control module can be configured on the boarding bridge as an auxiliary measure in the remote control system. Based on the temperature data, the operating parameters of the air conditioning system and ventilation fans on the boarding bridge can be adjusted directly. The airport control system has higher control over the planned start-up and shutdown, actual start-up and shutdown, and operating parameter adjustment of the air conditioning system and ventilation fans on the boarding bridge than the control module has over the air conditioning system and ventilation fans on the boarding bridge.

[0005] With this optimized configuration, the airport control system can schedule the start / stop and adjust the operating parameters of the air conditioning system and ventilation fans on the boarding bridge through servers, controllers, and networking equipment. The control module configured on the boarding bridge can adjust the operating parameters of the air conditioning system and ventilation fans locally, further precisely adjusting the internal ambient temperature of the boarding bridge. At the same time, it reduces the communication frequency between the boarding bridge and the airport control system, eliminating the need for the airport control system to monitor the ambient temperature control of individual boarding bridges in real time, thus reducing the computational load on the airport control system regarding the ambient temperature control of the boarding bridges.

[0006] The inventors have proposed a remote control device for air conditioning on boarding bridges. By configuring an independent PLC control module for each boarding bridge, the air conditioning and fan equipment on the boarding bridge can be controlled and regulated. At this time, the airport control system needs to realize remote control of the air conditioning and fan equipment through the PLC control module. The configuration technology of PLC control module, air conditioning equipment and fan in this solution is mature and simplifies the maintenance pressure and technical difficulty of airport ground staff.

[0035] See attached document Figure 1-6 This utility model provides a remote control device for air conditioning of boarding bridge, including a bridge compartment 1. A vehicle-mounted air conditioner 2 is fixedly installed on the top of the bridge compartment 1. The vehicle-mounted air conditioner 2 is connected to a PLC control module via an air conditioning remote controller. Cross-flow fans 3 are fixedly installed on both the left and right sides of the bottom of the bridge compartment 1. The cross-flow fans 3 are connected to the PLC control module via relays. The input terminal of the PLC control module is connected to the airport control system. A temperature sensor and an air quality sensor are connected to the analog input terminal of the PLC control module.

[0036] In this embodiment, a chassis bridge 11 is fixedly installed at the bottom of the bridge car 1, observation windows are fixedly installed on both the left and right sides of the bridge car 1, a heat insulation layer is fixedly installed on the inner side of the box wall of the bridge car 1, and multiple temperature sensors and air quality sensors are fixedly connected to the top of the inner wall of the bridge car 1 respectively.

[0037] The insulation layer design of bridge compartment 1 can be selected from rock wool board, extruded polystyrene board, polyurethane foam, graphite modified polystyrene board or aerogel felt, etc., according to design requirements.

[0038] Temperature and air quality sensors are installed inside bridge compartment 1 to facilitate the PLC control module to obtain ambient temperature data inside bridge compartment 1 in a timely manner and report it to the airport control system. The airport control system, in conjunction with the information in the overall flight schedule, sends start / stop plan information for the onboard air conditioner 2 and cross-flow fan 3, as well as parameter settings such as wind speed and temperature, to the corresponding boarding bridge. The PLC control module then completes the specific control processing of the onboard air conditioner 2 and cross-flow fan 3.

[0039] In this embodiment, the air outlet of the vehicle air conditioner 2 extends to the top left and right sides of the inner wall of the bridge compartment 1. An exhaust pipe 21 is fixedly installed at the air outlet of the vehicle air conditioner 2, and the outer sides of the two exhaust pipes 21 are fixedly connected to the top left and right sides of the inner wall of the bridge compartment 1, respectively.

[0040] The vehicle air conditioner 2 cools or heats the interior of the bridge compartment 1 through the exhaust pipe 21. This design follows the existing structure without adjustment, reducing the production cost and maintenance difficulty of the product.

[0041] In this embodiment, an exhaust pipe 31 is fixedly installed at the air inlet of the cross-flow fan 3. The air inlet of the exhaust pipe 31 extends to the bottom of the inner wall of the bridge chamber 1. An air damper 32 is movably connected at the air inlet of the exhaust pipe 31. One end of the air damper 32 is fixedly connected to the output end of the start-stop motor 33. The outer side of the start-stop motor 33 is fixedly connected to the outer side of the exhaust pipe 31. The start-stop motor 33 is communicatively connected to the PLC control module.

[0042] The air quality sensor and PLC control module work together to detect the air quality inside the bridge compartment 1. Combined with the temperature sensor to detect the temperature data inside the bridge compartment 1, the PLC control module can coordinate the vehicle air conditioner 2 and the cross-flow fan 3 to complete the rapid airflow treatment inside the bridge compartment 1 and prevent the air quality inside the bridge compartment 1 from deteriorating.

[0043] When the cross-flow fan 3 and the exhaust pipe 31 work together to quickly exhaust the polluted air in the bridge chamber 1, the PLC control module and the start / stop motor 33 work together to open the damper 32 on the exhaust pipe 31, so that the air in the bridge chamber 1 can be discharged by the cross-flow fan 3 through the damper 32 and the exhaust pipe 31.

[0044] In this embodiment, connecting seats 4 are fixedly provided on both the left and right sides of the bridge car 1.

The bottom of the housing of the electric rotary platform 43 is fixedly connected to the top of the frame 5. A reduction motor 51 is fixedly provided at the bottom of the frame 5. The output end of the reduction motor 51 is fixedly sleeved with the middle part of the rotating shaft 52. Wheels 53 are fixedly provided at both the left and right ends of the rotating shaft 52.

The geared motor 51 works with the rotating shaft 52 to complete the rotation of the wheels 53 under the frame 5. Combined with the electric rotary platform 43, the bridge car 1 can be adjusted for telescopic and deflection.

[0046] The airport control system sends start / stop signals and related parameter settings for the onboard air conditioner 2 and cross-flow fan 3 in the corresponding bridge compartment 1 to the PLC control module based on information from the overall flight schedule. The PLC control module obtains temperature and air quality data within bridge compartment 1 from temperature and air quality sensors, and makes specific settings for the onboard air conditioner 2 and cross-flow fan 3 in the corresponding bridge compartment 1. At this time, the control of the onboard air conditioner 2 and cross-flow fan 3 in bridge compartment 1 is dually managed by the airport control system and the PLC control module, serving as backups for each other. For safety management purposes, the PLC control module does not involve the control of the drive and altitude adjustment components of bridge compartment 1, simplifying the debugging requirements of the PLC control module and reducing the maintenance pressure and technical difficulty for ground staff.

[0047] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
