[0014] Beneficial Effects

[0015] The present invention provides a platform door control unit that can reduce hard-wire cables. Compared with the prior art, it has the following beneficial effects:

[0016] 1. In the present invention, through the heat dissipation and dehumidification mechanism, the door controller door control unit body will emit heat when working for a long time, and the heat will fill the inside of the door controller shell. When the user starts the motor, the output end of the motor drives the transmission blade to rotate. The transmission blade can send the hot air inside the door controller shell into the heat dissipation pipe. The hot air moves along the heat dissipation pipe. When it moves to the heat dissipation fins, the heat dissipation fins can absorb the heat and dissipate the heat to the surrounding air. When the air flows, it can take away the heat of the heat dissipation fins, thereby reducing the temperature of the hot air inside the heat dissipation pipe. After the temperature is reduced, the hot air enters the door controller shell from the other end of the heat dissipation pipe. Different from the traditional method of opening heat dissipation holes in the door controller shell and building in a heat dissipation fan, it can prevent external moisture from radiating from the heat dissipation pipe. On the one hand, the hole enters the interior of the door controller housing to corrode the electronic components inside it. On the other hand, it can prevent external dust from entering the interior of the door controller housing through the heat dissipation hole to affect the normal operation of its internal components. As the transmission blade rotates, the transmission blade can rotate the worm through the extension rod, and the worm drives the worm wheel to rotate. The worm wheel can rotate the stirring blade through the transmission rod. When the stirring blade rotates, on the one hand, it can prevent the desiccant particles inside the dehumidification box from agglomerating. On the other hand, it can improve the overall utilization rate of the desiccant particles and increase their service life. It is also convenient to replace the desiccant particles. When replacing, you only need to pull the sealing cover to take out the desiccant particles inside the dehumidification box. When replacing new desiccant particles, you can open the sealing cover and enter the interior of the dehumidification box through the through groove.

[0017] 2. In the present invention, by setting up the door controller door control unit body, wireless communication is directly carried out with the door controller door control unit body by installing a wireless transceiver on the vehicle, and the opening and closing of the platform door is controlled by the driving situation of a single vehicle. Similarly, the status of the platform door system is directly fed back to the corresponding vehicle in real time. The door opening process: after the vehicle arrives at the station, the door opening command is sent to the door controller door control unit body through the wireless transceiver to realize the synchronous opening of the vehicle door and the platform door. The door closing process: after the vehicle completes boarding and disembarking, the door closing command is sent to the door controller door control unit body through the wireless transceiver to realize the synchronous closing of the vehicle door and the platform door. Closing and locking: after the platform door is closed, the closing and locking signal is uploaded to the vehicle system through the wireless transceiver. Interlock release: the platform door failure is not When closing, after the on-site personnel confirm safety, they operate the interlock contact signal, and the vehicle enters or exits the platform. The wireless communication platform door control unit door controller door control unit body is equipped with a local control panel terminal control panel interface, and its control priority is greater than the wireless signal door opening and closing.

[0047]

[0048] From the experimental table content, the experimental steps and test content cover the core functions and important performance indicators of the door control unit of the wireless communication station door controller. The following is a key analysis and summary of the experimental table:

[0049] Example 1: Platform door control solution for simplified signal system

[0050] Background: For low-volume projects, due to the high cost of the signal system, a simplified solution is adopted to reduce the overall cost.

[0051] Implementation process: Use the vehicle wireless transceiver to communicate directly with the platform door control unit to reduce dependence on the signal system, and directly feed back the switch status of the platform door to the vehicle system without the need for complex signal system transit. Only set up signal system interfaces at necessary locations for status monitoring and emergency linkage to avoid full coverage construction.

[0052] Expected effects: Reduced dependence on the signal system, significantly reduced project costs, simplified control links, reduced system interaction levels, and meeting the budget requirements of low-volume projects.

[0053] Example 2: Direct control mode to reduce signal interaction

[0054] Background: In traditional solutions, there are many interactive links between vehicles, platform doors, and signal systems, which increases the number of failure points and affects operational stability.

[0055] Implementation process: The vehicle directly sends the door opening and closing signal to the platform door control unit to reduce the intermediate control links of the signal system, establish a point-to-point communication mechanism between the vehicle and the platform door, shorten the signal path, and set up safety logic: the platform door and the vehicle must be interlocked to ensure that the vehicle cannot be started when the door is not completely closed.

[0056] Expected effects: Eliminate redundant control links, significantly reduce the risk of failure, improve system response speed, achieve rapid linkage between car doors and platform doors, make operation and maintenance more efficient, and reduce hidden problems caused by complex systems.

[0057] Example 3: Wireless control reduces hard wiring costs

[0058] Background: The construction cost of hard-wire control is high, especially in low-volume projects, where the cost of hard-wire laying accounts for a significant proportion.

[0059] Implementation process: Use wireless communication to replace traditional hard-wired control. Vehicles interact with platform door control units in real time through wireless transceivers, reducing the laying of hard-wired cables and retaining only hard-wired interfaces in key locations (such as emergency control). During the construction process, statistics are collected on the time, manpower and material savings of wireless solutions compared to hard-wired installations.

[0060] Expected effects: Construction time is shortened, construction personnel are reduced, wiring complexity is reduced, and the total project cost is significantly reduced, especially in scenarios with long lines or many sites, which improves construction flexibility and adapts to more complex environments.

[0061] Working principle: The door controller door control unit body 5 will emit heat when working for a long time, and the heat will fill the inside of the door controller housing 1. The user starts the motor 207, and the output end of the motor drives the transmission blade 208 to rotate. The transmission blade 208 can send the hot air inside the door controller housing 1 into the heat dissipation pipe 201. The hot air moves along the heat dissipation pipe 201. When it moves to the heat dissipation fins 203, the heat dissipation fins 203 can absorb the heat and dissipate the heat to the surrounding air. When the air flows, it can take away the heat of the heat dissipation fins 203, thereby reducing the temperature of the hot air inside the heat dissipation pipe 201. After the temperature is reduced, the hot air enters the door controller housing 1 from the other end of the heat dissipation pipe 201. Different from the traditional method of opening heat dissipation holes in the door controller housing 1 and building a heat dissipation fan, On the one hand, it can prevent external moisture from entering the door controller housing 1 through the heat dissipation holes and corroding the internal electronic components thereof; on the other hand, it can prevent external dust from entering the door controller housing 1 through the heat dissipation holes and affecting the normal operation of the internal components thereof. As the transmission blade 208 rotates, the transmission blade 208 can rotate the worm 210 through the extension rod 209, and the worm 210 drives the worm wheel 211 to rotate. The worm wheel 211 can rotate the stirring blade 214 through the transmission rod 216. When the stirring blade 214 rotates, on the one hand, it can prevent the desiccant particles 215 inside the dehumidification box 202 from agglomerating, and on the other hand, it can improve the overall utilization rate of the desiccant particles 215 and improve their service life. In addition, it is also relatively convenient to replace the desiccant particles 215. When replacing, only the pulling The desiccant particles 215 in the dehumidification box 202 can be taken out by moving the sealing cover 205. The sealing cover 205 can be opened to replace new desiccant particles 215, and the interior of the dehumidification box 202 can be entered through the through slot 213. The wireless transceiver installed on the vehicle directly communicates with the door controller door control unit body 5 wirelessly. The opening and closing of the platform door is controlled by the driving conditions of a single vehicle. Similarly, the status of the platform door system is directly fed back to the corresponding vehicle in real time. The door opening process: After the vehicle arrives at the station, the door opening command is sent to the door controller door control unit body 5 through the wireless transceiver to realize the synchronous opening of the vehicle door and the platform door. The door closing process: After the vehicle completes boarding and disembarking, the door closing command is sent to the door controller door control unit body 5 through the wireless transceiver to realize the synchronous closing of the vehicle door and the platform door. Closed and locked: After the platform door is closed, the closed and locked signal is uploaded to the vehicle system through the wireless transceiver. Interlock release: When the platform door fails to close, the on-site personnel confirm safety and operate the interlock contact signal, and the vehicle enters or exits the platform. The platform door control unit of the wireless communication is equipped with a local control panel terminal control panel interface 3, and its control priority is greater than the wireless signal door opening and closing. The platform door control unit of the wireless communication has a central control panel interface 3 monitoring function, which can upload the door status and alarm information to the central control panel monitoring system. The door controller of the wireless communication realizes the control of the corresponding platform through the station number setting, which not only optimizes the signal system setting, but also reduces the construction cost and saves space.While ensuring the functions, the interactive links are reduced, the linkage failure rate is reduced, and the hard wire cables are effectively reduced, which facilitates the project construction.
