Description

Technical Field

[0001] This invention relates to a platform screen door control system for rail transit, and particularly to a platform screen door signal transmission system, a fully electronic platform screen door system, and a control method. Background Technology

[0002] The existing platform screen door system's central control panel (PSC) is connected to other equipment such as the PSL (local control panel), IBP (integrated backup panel), and DCU (sliding door motor control unit) via hard-wired cables to exchange various control commands and status information. The cable is a single channel, resulting in low transmission availability. The existing platform screen door system uses a single CPU for calculation, which leads to low security and availability.

[0003] Due to the large number of equipment such as PSL, IBP, and DCU on the platform, a large number of hard-wired cables are required, resulting in high cable costs. This increases the workload and construction period for installation and commissioning, and leads to a large number of equipment burnouts due to mixed wiring and electrical issues during on-site wiring and commissioning. At the same time, troubleshooting line faults is difficult after the line opens, and operation and maintenance remain unchanged, causing train delays and affecting passenger travel.

[0091] The second electronic control unit compares the first output signal and the second output signal generated by the two second logic units. When the first output signal generated by the two second logic units is consistent and the second output signal is also consistent, one of the second logic units sends the first output signal to the gate lock and sends the second output signal to the platform motor, controlling the gate lock and the platform motor to work together.

When one host unit does not receive the main monitoring signal from the other within a set time, it indicates that the host unit has detected a functional fault related to the opening and closing of the platform door in the other host unit, and the platform control host enters a safe state.

[0094] If one of the main units does not receive the secondary monitoring signal from the other within a set time, it indicates that the main unit has detected a functional fault in the other main unit that is unrelated to the opening and closing of the platform door, and the normal main unit will then transmit the signal.

[0095] Optionally, the method for mutual testing between the two station control hosts in the signal processor includes:

When one of the first logic units does not receive the main monitoring signal sent by the other within a set time, it indicates that the first logic unit has detected a functional fault related to the opening and closing of the platform door in the other first logic unit, and the first electronic control unit enters a safe state.

[0099] If one of the first logic units does not receive the secondary monitoring signal sent by the other party within a set time, it indicates that the first logic unit has detected a functional failure in another first logic unit that is unrelated to the opening and closing of the platform door, and the normal first logic unit will then carry out signal transmission.

[0100] Optionally, the method for mutual detection among the second logic units in the second electronic control unit includes:

[0101] Two second logic units exchange main monitoring signals and auxiliary monitoring signals in real time via a transmission bus. When one of the second logic units does not receive the main monitoring signal sent by the other within a set time, it indicates that the second logic unit has detected a functional fault related to the opening and closing of the platform door in the other second logic unit, and the second electronic control unit enters a safe state.

[0102] If one of the second logic units does not receive the secondary monitoring signal sent by the other party within a set time, it indicates that the second logic unit has detected a functional failure in another second logic unit that is unrelated to the opening and closing of the platform door, and the normal second logic unit will then carry out the signal transmission.

[0103] Compared with the prior art, the technical solution of the present invention has at least the following beneficial effects:

[0104] The platform door signal transmission system of this invention uses a data transmission link between the platform control host, the first electronic control unit, and the second electronic control unit, replacing the existing single-channel transmission via hard-wired cables. This reduces wiring installation and debugging workload by 80%, completely avoids wiring and electrical mismatch accidents caused by wiring errors, and improves fault diagnosis efficiency by 80%, enhancing transmission availability. Furthermore, the platform control host, the first electronic control unit, and the second electronic control unit all employ cross-checking technology and BIT (Browser In-Process) technology to achieve hierarchical classification and processing of safety functions related to platform door opening and closing and non-safety functions unrelated to platform door opening and closing, thereby improving the safety and availability of the platform door signal transmission system.

[0119] The platform door status message is forwarded by the second electronic control unit 3; the manual control signal can reflect the operation status of the manual control panel, including: safety commands that require control of the platform door opening and closing through the manual control panel and non-safety commands that do not require control of the platform door opening and closing.

[0120] In a preferred embodiment, the platform screen door signal transmission system includes multiple platform control hosts 1, forming a redundant structure. Preferably, as... Figure 2 As shown, the signal processor consists of two platform control hosts 1. When one of the platform control hosts 1 in the signal processor fails, the other platform control host 1 takes over as a backup to ensure the continuous operation of the platform door signal transmission system. At this time, the two platform control hosts 1 can perform mutual checks. When one of the platform control hosts 1 in the signal processor fails (i.e., enters a safe state), the other platform control host 1 will be activated.

[0121] The platform control host 1 includes two host units 1-1, which communicate with each other via a transmission bus. Each host unit 1-1 engages in bidirectional signal transmission with the signaling system. During downlink data transmission, each host unit 1-1 receives a first control signal or a second control signal from the signaling system; during uplink data transmission, each host unit 1-1 forwards platform door status messages and non-safety commands to the signaling system. Each host unit 1-1 also engages in bidirectional signal transmission with a first electronic control unit 2. During downlink data transmission, each host unit 1-1 forwards a first control signal to the first electronic control unit 2; during uplink data transmission, each host unit 1-1 receives manual control signals generated by the first electronic control unit 2. Furthermore, each host unit 1-1 engages in bidirectional signal transmission with a second electronic control unit 3. During downlink data transmission, each host unit 1-1 forwards a second control signal or a safety command to the second electronic control unit 3; during uplink data transmission, each host unit 1-1 receives platform door status messages forwarded by the second electronic control unit 3.

[0122] Specifically, each of the host units 1-1 includes: a host communication module 1-11 and a host control module 1-12.

[0123] The host communication module 1-11 transmits signals bidirectionally with the signaling system. During downlink data transmission, the host communication module 1-11 can receive a first control signal or a second control signal sent by the signaling system; during uplink data transmission, the host communication module 1-11 can forward platform door status messages and non-safety commands to the signaling system. The host communication module 1-11 also transmits signals bidirectionally with the first electronic control unit 2. During downlink data transmission, the host communication module 1-11 forwards a first control signal to the first electronic control unit 2; during uplink data transmission, the host communication module 1-11 can receive manual control signals generated by the first electronic control unit 2. Furthermore, the host communication module 1-11 transmits signals bidirectionally with the second electronic control unit 3. During downlink data transmission, the host communication module 1-11 can forward a second control signal or a safety command to the second electronic control unit 3; during uplink data transmission, the host communication module 1-11 receives platform door status messages forwarded by the second electronic control unit 3. The host communication module 1-11 and the host control module 1-12 communicate bidirectionally. The host communication module 1-11 can send a first control signal, a second control signal, or a manual control signal to the host control module 1-12. The host communication module 1-11 can also receive the first control signal, the second control signal, or the manual control signal forwarded by the host control module 1-12.

[0124] The host control module 1-12 can process the first control signal, the second control signal, and the manual control signal, control the transmission of the first control signal to the first electronic control unit 2, control the transmission of the second control signal to the second electronic control unit 3, control the transmission of safety commands in the manual control signal to the second electronic control unit 3, and control the transmission of non-safety control commands in the manual control signal to the signal system.

[0125] When the host control module 1-12 receives a control signal, it needs to judge the control signal to determine whether the host unit 1-1 needs to forward the control signal to the second electronic control unit 3. When the control signal is the second control signal, the host control module 1-12 sends the control signal (i.e., the second control signal) to the second electronic control unit 3 through the host communication module 1-11; when the control signal is the first control signal, the host control module 1-12 sends the control signal (i.e., the first control signal) to the first electronic control unit 2 through the host communication module 1-11.

[0126] Simultaneously, when the host control module 1-12 receives a manual control signal, it needs to judge the signal to determine whether the host unit 1-1 needs to forward it to the second electronic control unit 3. When the manual control signal is a safety command, the host control module 1-12 controls the host communication module 1-11 to send the safety command to the second electronic control unit 3; when the manual control signal is a non-safety command, the host control module 1-12 controls the host communication module 1-11 to send the non-safety command to the first electronic control unit 2.

[0127] Furthermore, the two host units (including Figure 1 Units 1-1 and 1-2 employ mutual detection and BIT technology, interacting via a transmission bus and capable of exchanging main and secondary monitoring signals in real time to monitor for faults in the two main units 1-1. During mutual detection between the two main units 1-1, if one main unit 1-1 fails to receive the main monitoring signal from the other within a set time, it indicates that the main unit 1-1 has detected a fault in the safety function (i.e., the function related to platform door opening and closing) of the other main unit 1-2. In this case, the platform control host 1 enters a safety state to enhance its security and prevent it from forwarding incorrect commands to the first electronic control unit 2 or the second electronic control unit 3. If one main unit 1-1 fails to receive the secondary monitoring signal from the other within a set time, it indicates that the main unit 1-1 has detected a fault in the non-safety function (i.e., the function unrelated to platform door opening and closing) of the other main unit 1-2. In this case, the normal main unit forwards the control signal, improving the availability of the platform control host 1.

[0128] Furthermore, the two host units 1-1 together form a heterogeneous structure of the platform control host 1 to prevent the platform control host 1 from forwarding incorrect control signals to the first electronic control unit 2 or the second electronic control unit 3. When the control signals forwarded by the two host units 1-1 are the same (i.e., both are "second control signals" or both are "first control signals"), one of the host units 1-1 forwards the control signal to the first electronic control unit 2 or the second electronic control unit 3; when the control signals forwarded by the two host units 1-1 are different, the platform control host 1 enters a safe state and no longer sends messages to the first electronic unit or the second electronic unit.

[0129] In a preferred embodiment, such as Figure 2 As shown, the platform screen door signal transmission system uses two platform control hosts 1, forming a redundant structure.

[0130] The first electronic control unit 2 is capable of manually monitoring and controlling the opening and closing of the platform doors. The first electronic control unit 2 communicates bidirectionally with the platform control host 1. During downlink data transmission, the first electronic control unit 2 receives and processes the first control signal forwarded by the signal processor; during uplink data transmission, the first electronic control unit 2 sends its generated manual control signal to the platform control host 1. The first electronic control unit can generate a non-safety output signal based on the first control signal to update the operating status of the manual control panel; the first electronic control unit generates the manual control signal based on the safety acquisition signal. The first electronic control unit 2 communicates bidirectionally with the manual control panel. During downlink data transmission, the first electronic control unit 2 sends a non-safety output signal to the manual control panel; during uplink data transmission, the first control unit can receive the safety acquisition signal sent by the manual control panel. The non-safety output signal is used to update the operating status of the manual control panel.

[0131] The first electronic control unit 2 includes: two first logic units (including...) Figure 1In the diagram (2-1 and 2-2), the two first logic units 2-1 are connected via a transmission bus. Each first logic unit 2-1 performs bidirectional signal transmission with the platform control host 1. During downlink data transmission, each first logic unit 2-1 can receive and process the first control signal sent by the platform control host 1, perform logical calculations, and generate a non-safety output signal. During uplink data transmission, each first logic unit 2-1 sends its generated manual control signal to the platform control host 1. Each first logic unit 2-1 can generate a non-safety output signal based on the first control signal to update the operating status of the manual control panel. Each first logic unit 2-1 generates the manual control signal based on the safety acquisition signal. Each first logic unit 2-1 performs bidirectional signal transmission with the manual control panel. During downlink data transmission, each first logic unit 2-1 can send a non-safety output signal to the manual control panel to update the monitoring status of the platform door by the terminal device 1 in real time, enabling the manual control panel to generate a safety acquisition signal. During uplink data transmission, the first control unit can receive the safety acquisition signal sent by the manual control panel and generate a manual control signal based on the safety acquisition signal.

[0132] Furthermore, when the operator controls the opening and closing of the platform door through the manual control panel, the manual control signal generated by the manual control panel is a safety command. At this time, the first electronic control unit 2 sends the safety command to the second electronic control unit 3 through the platform control host 1. When the operator does not perform any operation on the manual control panel, the manual control signal generated by the manual control panel is a non-safety command. At this time, the first electronic control unit 2 sends the safety command to the signaling system through the platform control host 1.

[0133] Specifically, each of the first logic units 2-1 includes: a first communication module 2-11, a first control module 2-12, and a first acquisition and driving module 2-13.

[0134] The first communication module 2-11 transmits signals bidirectionally with the signal processor. During downlink data transmission, the first communication module 2-11 can receive the first control signal forwarded by the station control host 1; during uplink data transmission, the first communication module 2-11 sends the generated manual control signal to the station control host 1. The first communication module 2-11 also transmits signals bidirectionally with the first control module 2-12. The first communication module 2-11 can forward the first control signal to the first control module 2-12; the first communication module 2-11 can also receive the non-safety output signal generated by the first control module 2-12. Furthermore, the first communication module 2-11 transmits signals bidirectionally with the first acquisition and drive module 2-13. During downlink data transmission, the first communication module 2-11 can forward the non-safety output signal to the first acquisition and drive module 2-13; during uplink data transmission, the first communication module 2-11 can receive the safe acquisition signal forwarded by the first acquisition and drive module 2-13.

[0135] The first control module 2-12 integrates the functions of the local control panel (PSL) and the integrated backup panel (IBP), enabling the first electronic control unit 2 to allow manual control of the platform door opening and closing and generate manual control signals. The first control module 2-12 and the first communication module 2-11 perform bidirectional signal transmission. During downlink data transmission, the first control module 2-12 can receive the first control signal forwarded by the first communication module 2-11 and generate a non-safety output signal based on the first control signal sent by the host communication module 1-11 to control the operating status of the terminal device 1 (i.e., the display status of the manual control panel). During uplink data transmission, the first control module 2-12 can generate a manual control signal based on the safety acquisition signal sent by the manual control panel.

[0136] The first data acquisition module 2-13 and the first communication module 2-11 perform bidirectional signal transmission. During downlink data transmission, the first data acquisition module 2-13 can receive unsecured output signals forwarded by the first communication module 2-11. During uplink data transmission, the first data acquisition module 2-13 forwards secure acquisition signals to the first communication module 2-11. Furthermore, the first data acquisition module 2-13 and the terminal device 1 perform bidirectional signal transmission. During downlink data transmission, the first data acquisition module 2-13 can forward unsecured output signals to the terminal device 1 (i.e., the manual control panel), controlling the terminal device 1 to execute unsecured output signals and generate secure acquisition signals. Simultaneously, during uplink data transmission, the first data acquisition module 2-13 can receive the secure acquisition signals generated by the terminal device 1.

[0137] Furthermore, the two first logic units 2-1 employ mutual detection and BIT technology, interacting via a transmission bus to exchange main and secondary monitoring signals in real time, thereby monitoring for faults in both units. During mutual detection, if one first logic unit 2-1 fails to receive the main monitoring signal from the other within a set time, it indicates that the first logic unit 2-1 has detected a fault in the safety function of the other first logic unit 2-2. In this case, the first electronic control unit 2 enters a safety state to enhance its security, preventing it from sending incorrect execution commands to the terminal device 1. Conversely, if one first logic unit 2-1 fails to receive the secondary monitoring signal within a set time, it indicates that the first logic unit 2-1 has detected a fault in the non-safety function of the other first logic unit 2-2. In this case, the normal first logic unit controls the input, operation, and output of the first logic unit, improving the availability of the first electronic control unit 2.

[0138] Furthermore, the two first logic units 2-1 together constitute the heterogeneous structure of the first electronic control unit 2, enabling comparison of the signals generated by the two units. When the non-safety output signals generated by the two first logic units 2-1 are the same, one of the first logic units 2-1 sends a non-safety output signal to the terminal device 1 to update the terminal device 1's monitoring status of the platform door; when the non-safety output signals generated by the two first logic units 2-1 are different, the first electronic control unit 2 enters a safe state and no longer sends safe output signals. When the manual control signals generated by the two first logic units are the same (both control signals are either safe commands or non-safety commands), one of the first logic units 2-1 sends a manual control signal to the host communication module 1-11 of the platform control host 1; when the manual control signals generated by the two first logic units 2-1 are different, the first electronic control unit 2 enters a safe state and no longer sends any signals.

[0139] When the first electronic control unit 2 needs to manually operate the platform door opening and closing, the platform control host 1 forwards the first control signal sent by the signal system to each first communication module 2-11 in the first electronic control unit 2, and then sends it to the corresponding first control module 2-12 through the first communication module 2-11. The first control module 2-12 generates a non-safety output signal based on the first control signal. The non-safety output signals generated by the two first logic units 2-1 are compared. When the non-safety output signals generated by the two are consistent, the non-safety output signal is sent to the first data acquisition module 2-13 through the first communication module 2-11, and the first data acquisition module 2-13 outputs a non-safety output signal to the terminal device 1, controlling the terminal device 1 to execute the non-safety output signal and completing the update of the platform door monitoring status in the terminal device 1. The operator can control the opening and closing status of the platform door through the terminal device 1 according to the platform door monitoring status of the terminal device 1, so that the manual control panel generates a safety acquisition signal.

[0140] Simultaneously, the first acquisition module 2-13 in each first logic unit 2-1 acquires the safety acquisition signal of the terminal device 1 and sends the safety acquisition signal to its first communication module 2-11, which then forwards the safety acquisition signal to the first control module 2-12. The first control module 2-12 in each first logic unit 2-1 calculates and obtains the manual control signal based on the safety acquisition signal. Comparing the manual control signals of the two first logic units 2-1, if the signals are inconsistent, the first electronic control unit 2 enters a safe state; if the logical calculation results of the two first logic units 2-1 are consistent, the first communication module 2-11 in one of the first logic units sends the manual control signal to the station control host 1. Then, the platform control host 1 determines the transmission direction of the manual control signal. When the manual control signal is a safety command, it means that the platform door is opened and closed through the manual control panel. At this time, the platform control host 1 forwards the safety command to the second electronic control unit 3, which then controls the opening and closing of the platform door. When the manual control signal is a non-safety command, it means that no operation has been performed on the manual control panel. At this time, the platform control host 1 forwards the non-safety command to the signaling system.

[0141] The second electronic control unit 3 can control the opening and closing of the platform door according to the signal system forwarded by the platform control host 1 or the second control signal sent by the first electronic control unit 2.

[0142] The second electronic control unit 3 transmits signals bidirectionally with the platform control host 1. During downlink data transmission, the second electronic control unit 3 receives and processes a second control signal or safety command sent by the signal processor, and generates a first output signal and a second output signal based on the second control signal or safety command. During uplink data transmission, the second electronic control unit 3 sends platform door status messages to the platform control host 1. The second electronic control unit 3 also transmits signals bidirectionally with the platform door equipment. During downlink data transmission, the second electronic control unit 3 sends a first output signal and a second output signal to the platform door equipment; during uplink data transmission, the second electronic control unit 3 receives platform door status messages sent by the platform door equipment.

[0143] The platform screen door equipment includes: a gate lock (i.e. Figure 1 The platform gate status message includes: a gate status message reflecting the gate's operating status and a motor status message reflecting the platform motor's operating status; the first output signal is used to control the operation of the gate, and the second output signal is used to control the operation of the platform motor.

[0144] The second electronic control unit 3 includes: two second logic units (including...) Figure 1 (3-1 and 3-2) The signal transmission is via a transmission bus. Each second logic unit 3-1 transmits signals bidirectionally with the platform control host 1. During downlink data transmission, each second logic unit 3-1 can receive and process the second control signal or safety command sent by the platform control host 1, and generate a first output signal and a second output signal according to the second control signal or safety command. During uplink data transmission, each second logic unit 3-1 can send a platform door status message to the signal processor. Each second logic unit 3-1 also transmits signals bidirectionally with the gate lock. During downlink data transmission, each second logic unit 3-1 can send a first output signal to the gate lock to control its operation and generate a gate lock status message. During uplink data transmission, each second logic unit 3-1 can receive the gate lock status message generated by the gate lock. Each of the second logic units 3-1 transmits signals bidirectionally with the platform motor. During downlink data transmission, each of the second logic units 3-1 can send a second output signal to the platform motor to control the operation of the platform motor and generate a motor status message. During uplink data transmission, each of the second logic units 3-1 can receive the motor status message generated by the platform motor.

[0145] Specifically, each of the second logic units 3-1 includes: a second communication module 3-11, a second control module 3-12, a second acquisition and driving module 3-13, and a driving module 3-14.

[0146] The second communication module 3-11 transmits signals bidirectionally with the station control host 1. During downlink data transmission, the second communication module 3-11 can receive a second control signal or safety command forwarded by the station control host 1; during uplink data transmission, the second communication module 3-11 can forward gate status messages and motor status messages to the station control host 1. The second communication module 3-11 also transmits signals bidirectionally with the second control module 3-12, forwarding a second control signal or safety command to the second control module. The second communication module 3-11 can receive a first output signal and a second output signal generated by the second control module 3-12. Furthermore, the second communication module 3-11 transmits signals bidirectionally with the second acquisition and drive module 3-13. During downlink data transmission, the second communication module 3-11 can forward a first output signal to the second acquisition and drive module 3-13; during uplink data transmission, the second communication module 3-11 can receive gate status messages forwarded by the second acquisition and drive module 3-13. The second communication module 3-11 and the drive module 3-14 transmit signals bidirectionally. When the data is downlinked, the second communication module 3-11 can forward the second output signal to the drive module 3-14. When the data is uplinked, the second communication module 3-11 can receive the motor status message forwarded by the drive module 3-14.

[0147] The second control module 3-12 and the second communication module 3-11 transmit signals bidirectionally. The second control module 3-12 can receive the second control signal and safety command forwarded by the second communication module 3-11 and perform calculations to generate the first output signal and the second output signal, and then send the first output signal and the second output signal to the gate lock and the platform motor respectively.

[0148] The second data acquisition module 3-13 performs bidirectional signal transmission with the terminal device 2. When the data is downlinked, the second data acquisition module 3-13 can send a first output signal to the gate lock to control the operating state of the gate lock and make the gate lock generate a gate lock status message. When the data is uplinked, the second data acquisition module 3-13 sends the gate lock status message to the signal system through the second communication module 3-11.

[0149] The drive module 3-14 transmits signals bidirectionally with the platform motor. When the data is downlinked, the second acquisition and drive module 3-13 forwards the second output signal to the platform motor, drives the platform motor to execute the second output signal, controls the operating status of the platform motor, and causes the platform motor to generate a motor status message. When the data is uplinked, the drive module 3-14 receives the motor status message sent by the platform motor and sends the motor status message to the second communication module 3-11.

[0150] Furthermore, the two second logic units 3-1 adopt mutual detection and BIT technology, interact through the transmission bus, and can send main monitoring signals and secondary monitoring signals to each other in real time to monitor whether there is a fault in the two second logic units 3-1.

[0151] When the two second logic units 3-1 perform mutual checks, if one of the second logic units 3-1 fails to receive the main monitoring signal sent by the other within a set time, it indicates that the second logic unit 3-1 has detected a fault in the safety function part of the other second logic unit 3-2. At this time, the second electronic control unit 3 will enter a safety state to enhance its safety and prevent the second single control unit from sending incorrect execution commands to the terminal device 2 and the platform motor. If one of the second logic units 3-1 fails to receive the secondary monitoring signal sent by the other within a set time, it indicates that the second logic unit 3-1 has detected a fault in the non-safety function part of the other second logic unit 3-2. The normal second logic unit controls the input, operation and output of the second electronic control unit, thereby improving the availability of the second electronic control unit 3.

[0152] Furthermore, the two second logic units 3-1 together constitute the heterogeneous structure of the second electronic control unit 3, capable of generating a first output signal and a second output signal respectively, and exchanging data via a transmission bus. Comparing the first and second output signals generated by the two second logic units 3-1, if both the first and second output signals are identical, then one of the second logic units 3-1 sends the first and second output signals to the terminal device 2 and the platform motor respectively; otherwise, the second electronic control unit 3 enters a safe state.

[0153] When the second electronic control unit 3 needs to automatically control the opening and closing of the platform door, the second communication module 3-11 in each second logic unit 3-1 receives the second control signal or safety command sent by the platform control host 1 and forwards the second control signal to the second control module 3-12; the second control module 2-12 in each second logic unit 3-1 calculates according to the second control signal or safety command, generates a first output signal and a second output signal, and sends the first output signal and the second output signal to the second communication module 3-11. Comparing the first and second output signals generated by the two second logic units 3-1, when the first output signals generated by the two second logic units 3-1 are consistent and the second output signals are also consistent, the second communication module 3-11 in one of the second logic units 3-1 sends the first output signal to the second acquisition and drive module 3-13, and then to the terminal device 2 to control the operating status of the terminal device 2; at the same time, the second communication module 3-11 sends the second input signal to the drive module 3-14, and then to the platform motor to drive the platform motor to run; the gate lock (terminal device 2) and the platform motor work together to drive the sliding switch of the platform door. Simultaneously, the terminal device 2 generates a gate lock status message and sends it to the second communication module 3-11 through the second acquisition and drive module 3-13; the platform motor generates a motor status message and sends it to the second communication module 3-11 through the drive module 3-14; both the gate lock status message and the motor status message are sent to the platform control host 1 through the second communication module 3-11 to provide feedback to the platform control host 1 on whether the platform door has been successfully opened or closed.

[0154] In a preferred embodiment, the number of the second electronic control unit and the first electronic control unit can be flexibly configured according to actual needs, based on the number of platform screen door devices and the number of manual control panels, thereby improving the applicability of the platform screen door signal transmission system in multiple scenarios. Furthermore, each module in the platform control host, the first electronic control unit, and the second electronic control unit supports modular online plug-in and maintenance, facilitating fault handling and repair of the platform screen door signal transmission system and improving its fault handling efficiency.

[0155] Secondly, such as Figure 1 As shown, the present invention provides a fully electronic platform screen door system, including: the platform screen door signal transmission system, signal system, manual control panel and platform screen door equipment described above.

[0156] The signaling system can generate a first control signal or a second control signal based on the platform door status message, and can transmit signals bidirectionally with the platform door signal transmission system. When the data is downlinked, the signaling system can send the first control signal or the second control signal to the platform door signal transmission system; when the data is uplinked, the signaling system can receive the platform door status message sent by the platform door signal transmission system.

[0157] The manual control panel can update its operating status based on non-safety output signals and manually control the operation of the platform screen door equipment to generate safety acquisition signals. Furthermore, the manual control panel and the platform screen door signal transmission system transmit signals bidirectionally. During downlink data transmission, the manual control panel can receive non-safety output signals from the platform screen door signal transmission system; during uplink data transmission, the manual control panel can send safety acquisition signals to the platform screen door signal transmission system.

[0158] The platform screen door equipment includes a gate lock and a platform motor, and the opening and closing status of the platform screen door is controlled by the coordinated operation of the gate lock and the platform motor.

[0159] The gate lock changes its operating state according to the first output signal and generates a gate lock status message. The gate lock is capable of bidirectional signal transmission with the platform door signal transmission system. During downlink data transmission, the gate lock can receive the first output signal sent by the platform door signal transmission system; during uplink data transmission, the gate lock can send a gate lock status message to the platform door signal transmission system.

[0160] The platform motor can change its operating state and generate a motor status message based on the second output signal. The platform motor and the platform door signal transmission system transmit signals bidirectionally. During downlink data transmission, the platform motor can receive the second output signal sent by the platform door signal transmission system; during uplink data transmission, the platform motor can send a motor status message to the platform door signal transmission system.

[0161] In a preferred embodiment, the fully electronic platform screen door system further includes an integrated monitoring system. The integrated monitoring system transmits signals with the platform control host 1 and can record all signals sent by the platform control host 1, thereby enabling monitoring of the operating status of the platform screen door signal transmission system.

[0162] Thirdly, such as Figure 2 As shown, the present invention also provides a control method for a fully electronic platform screen door system, wherein the signal system generates a first control signal or a second control signal based on the platform screen door status message generated by the platform screen door device.

[0163] When the platform screen door is successfully opened or closed, the signal system sends a second control signal to the platform control host 1, which then transmits the second control signal to the second electronic control unit 3. The second electronic control unit 3 controls the operating status of the platform screen door equipment and sends the platform screen door status message fed back by the platform screen door equipment to the signal system through the signal controller.

[0164] When the platform door fails to open or close, the signal system sends a first control signal to the platform control host 1, which then transmits the first control signal to the first electronic control unit 2. The first control unit updates the operating status of the manual control panel and generates a manual control signal based on the safety acquisition signal fed back by the manual control panel, which is then sent to the signal processor.

[0165] Furthermore, when the platform screen door fails to open or close and manual operation is required, the operator operates the manual control panel. The first electronic control unit 2 receives the safety acquisition signal generated by the manual control panel, generates a safety command based on the safety acquisition signal, and sends the safety command to the platform control host 1. The platform control host 1 then sends the safety command to the second electronic control unit 3, which controls the opening and closing of the platform screen door. When the platform screen door fails to open or close and no further operation is required, no operation is needed on the manual control panel. The second electronic control unit 3 receives the safety acquisition signal generated by the manual control panel, generates a non-safety command based on the safety acquisition signal, and sends the non-safety command to the signaling system through the platform control host 1.

[0166] Example 1

[0167] like Figure 2 As shown, under normal circumstances, the platform doors can successfully open and close automatically when a train enters or leaves the platform:

[0168] Step A1: The signal system issues a control signal.

[0169] The signaling system sends control signals (i.e., the second control signal or the first control signal) to the host communication module 1-11 of the host unit 1-1 in the platform control host 1. When the signaling system recognizes that the platform door has been successfully opened or closed based on the platform door status message sent by the platform door device, the signaling system will send a "second control signal" to the platform control host 1, causing the platform door to automatically open or close according to the "second control signal".

[0170] Step A2: The station control host forwards the control signal.

[0171] Each host communication module 1-11 in the platform control host 1 receives the "second control signal" and forwards it to its corresponding host control module 1-12, which then judges the control signal. When the command received by the host communication module 1-11 is the "second control signal", it means that the "second control signal" needs to be sent to the second electronic control unit 3.

[0172] Meanwhile, the control signals forwarded by the two host units 1-1 in the platform control host 1 are compared. When both host units 1-1 forward the control signals, the "second control signal" is sent by one of the host units 1-1 in the platform control host 1 to the second electronic control unit 3. If the control signals forwarded by the two host units 1-1 are inconsistent, the platform control host 1 enters a safe state and stops forwarding any commands.

[0173] In a preferred embodiment, the platform screen door system uses two platform control hosts 1. When one platform control host 1 enters the safety platform, the other platform control host 1 repeats this step.

[0174] Step A3: The second electronic control unit drives the terminal device to operate.

[0175] The two third communication units in the second electronic control unit 3 receive the "second control signal" and forward it to their corresponding third control units; the third control units generate the first output signal and the second output signal.

[0176] The first output signal and the second output signal generated by the two second logic units 3-1 are compared. When the first output signal generated by the two second logic units 3-1 are consistent and the second output signal is also consistent, one of the second logic units 3-1 sends the first output signal and the second output signal to the end device 2 (gate lock) and the platform motor respectively; otherwise, the second electronic control unit 3 is controlled to enter the safe state and no longer sends any signals to the end device 2 and the platform motor.

[0177] One of the second logic units 3-1 sends the first output signal to the second acquisition and drive module 3-13 via the second communication module 3-11, and then to the end device 2 (gate lock); simultaneously, it sends the second output signal to the drive module 3-14 via the second communication module 3-11, and then to the platform motor. The gate lock and the platform motor work together to open and close the platform door.

[0178] In step A4, the terminal device 2 and the platform motor send feedback of the platform door status message to the external system.

[0179] After the terminal device 2 executes the first output signal, it sends a gate lock status message reflecting the current operating status of the terminal device 2 to the second electronic control unit 3. At the same time, after the platform motor executes the second output signal, it sends a motor status message reflecting the current operating status of the motor to the second electronic control unit 3. The second electronic control unit 3 then sends the gate lock status message and the motor status message to the external system through the platform control host 1, which is used to provide feedback to the external system on whether the platform door has been successfully opened and closed automatically.

[0180] Example 2

[0181] like Figure 2 As shown, this describes a scenario where the platform doors cannot open and close automatically when a train enters or leaves the platform:

[0182] Step B1: The signal system issues a control signal.

[0183] The signaling system sends either the second control signal or the first control signal to the host communication module 1-11 of the host unit 1-1 in the platform control host 1. When the signaling system detects that the platform door has failed to open or close based on the platform door status message, the signaling system will send the "first control signal" to the platform control host 1, so that the platform door can be controlled to open or close via the manual control panel.

[0184] Step B2: The station control host forwards the control signal.

[0185] Each host communication module 1-11 in the platform control host 1 receives the "first control signal" and forwards the "first control signal" to its corresponding host control module 1-12, which in turn sends it to the first electronic control unit 2.

[0186] Meanwhile, the control signals forwarded by the two host units 1-1 in the platform control host 1 are compared. When the control signals forwarded by the two host units 1-1 are both "first control signals", one of the host units 1-1 in the platform control host 1 sends the "first control signal" to the first electronic control unit 2. If the control signals forwarded by the two host units 1-1 are inconsistent, the platform control host 1 enters a safe state and stops forwarding any signals.

[0187] In a preferred embodiment, the platform screen door system uses two platform control hosts 1. When one platform control host 1 enters the safety platform, the other platform control host 1 repeats this step.

[0188] Step B3: The first electronic control unit updates the operating status of the manual control panel.

[0189] The two second communication units in the first electronic control unit 2 receive the "first control signal" and forward it to the corresponding second control unit; the second control unit generates a non-safety output signal.

[0190] The unsafe output signals generated by the two first logic units 2-1 are compared. When the unsafe output signals generated by the two first logic units are consistent, one of the first logic units 2-1 sends an unsafe output signal to the terminal device 1 (manual control panel); otherwise, the first electronic control unit 2 is controlled to enter the safe state and no longer sends any signals to the manual control panel.

[0191] One of the first logic units 2-1 sends the non-safety output signal to the first acquisition and drive module 2-13 through the first communication module 2-11, and then to the manual control panel. This updates the monitoring status of the platform door on the manual control panel in real time, and instructs the operator to open and close the platform door by operating the manual control panel.

[0192] Step B4: The platform screen door equipment sends a platform screen door status message back to the signaling system.

[0193] Terminal device 1 updates the monitoring status of the platform screen door, and the operator sends a safety acquisition signal reflecting the status of the manually operated platform screen door to the first electronic control unit 2 through the operation of terminal device 1.

[0194] The two first communication modules 2-11 in the first electronic control unit 2 receive the safety acquisition signal and send it to their corresponding first control module 2-12. The first control module 2-12 then generates a manual control signal (i.e., a safety command or a non-safety command) based on the safety acquisition signal.

[0195] The manual control signals generated by the two first logic units 2-1 are compared. When the manual control signals generated by the two first logic units 2-1 are consistent, one of the first logic units 2-1 sends a manual control signal to the platform control host 1; otherwise, the first electronic control unit 2 is controlled to enter a safe state and no longer sends any signals to the platform control host 1.

[0196] In a preferred embodiment, the platform screen door system uses two platform control hosts 1. When one platform control host enters the safety platform, the other platform control host 1 repeats this step.

[0197] Step B5: The platform control host forwards the manual control signal.

[0198] Each host communication module 1-11 in the platform control host 1 receives a "manual control signal" and forwards it to its corresponding host control module 1-12, which then controls the transmission of the manual control signal. When the "manual control signal" received by host communication module 1-11 is a "safety command," it indicates that a manual instruction has been issued to automatically open and close the platform door, requiring a "second control signal" to be sent to the second electronic control unit 3. When the "manual control signal" received by host communication module 1-11 is a "non-safety command," it indicates that no operation has been performed on the manual control panel, and the "non-safety command" will be sent to the signaling system to provide feedback on the operating status of the manual control panel.

[0199] Meanwhile, the manual control signals forwarded by the two host units 1-1 in the platform control host 1 are compared. When the "manual control signals" forwarded by the two host units 1-1 are consistent (i.e., both are "safe commands" or "non-safe commands"), it means that the "manual control signals" generated by the platform control host 1 are correct; if the "manual control signals" forwarded by the two host units 1-1 are inconsistent, the platform control host 1 enters a safe state and stops forwarding any signals.

[0200] Specifically, when the "manual control signals" forwarded by the two host units 1-1 are consistent and the manual control signal is a "safety command", one of the host units 1-1 of the platform control host 1 forwards the "safety command" to the second electronic control unit 3, repeating steps A3-A4 in Embodiment 1 to realize the opening and closing of the platform door; when the "manual control signals" forwarded by the two host units 1-1 are consistent and the manual control signal is a "non-safety command", the platform host forwards the "non-safety command" to the signaling system.

[0201] In summary, the platform screen door signal transmission system of the present invention utilizes a data transmission link to replace the existing single-channel transmission of hard-wired cables, avoiding wiring and electrical accidents caused by wiring errors during the assembly process; and utilizes cross-checking technology and BIT technology to achieve hierarchical classification and processing of safety functions related to platform screen door opening and closing and non-safety functions unrelated to platform screen door opening and closing, thereby improving the safety and availability of the platform screen door system.
