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

[0120] In a preferred embodiment, the platform door signal transmission system includes a plurality of the platform control hosts 1, so that the plurality of platform control hosts 1 form a redundant structure. Figure 2 As shown, the signal processor is composed of two platform control hosts 1. When one platform control host 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 inspection. When one platform control host 1 in the signal processor fails (i.e. enters a safe state), the other platform control host 1 will be started.

[0121] The platform control host 1 includes: 2 host units 1-1, and the 2 host units 1-1 transmit signals through a transmission bus. Each of the host units 1-1 performs two-way signal transmission with the signal system. When the data is downlink, each of the host units 1-1 can receive the first control signal or the second control signal sent by the signal system; when the data is uplink, each of the host units 1-1 can forward the platform door status message and the non-safety command to the signal system. Each of the host units 1-1 performs two-way signal transmission with the first electronic control unit 2. When the data is downlink, each of the host units 1-1 forwards the first control signal to the first electronic control unit 2; when the data is uplink, each of the host units 1-1 can receive the manual control signal generated by the first electronic control unit 2. Each of the host units 1-1 performs two-way signal transmission with the second electronic control unit 3. When the data is downlink, each of the host units 1-1 can forward the second control signal or the safety command to the second electronic control unit 3; when the data is uplink, each of the host units receives the platform door status message 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 performs two-way signal transmission with the signal system. When the data is downlink, the host communication module 1-11 can receive the first control signal or the second control signal sent by the signal system; when the data is uplink, the host communication module 1-11 can forward the platform door status message and the non-safety command to the signal system. The host communication module 1-11 performs two-way signal transmission with the first electronic control unit 2. When the data is downlink, the host communication module 1-11 forwards the first control signal to the first electronic control unit 2; when the data is uplink, the host communication module 1-11 can receive the manual control signal generated by the first electronic control unit 2. The host communication module 1-11 performs two-way signal transmission with the second electronic control unit 3. When the data is downlink, the host communication module 1-11 can forward the second control signal or the safety command to the second electronic control unit 3; when the data is uplink, the host communication module 1-11 receives the platform door status message forwarded by the second electronic control unit 3. The host communication module 1-11 and the host control module 1-12 transmit bidirectionally, and 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; and the host communication module 1-11 can 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 is capable of processing the first control signal, the second control signal and the manual control signal, controlling the first control signal to be transmitted to the first electronic control unit 2, controlling the second control signal to be transmitted to the second electronic control unit 3, controlling the safety command in the manual control signal to be transmitted to the second electronic control unit 3, and controlling the non-safety control command in the manual control signal to be transmitted to the signal system.

[0125] When the host control module 1-12 receives the control signal, it is necessary 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] At the same time, when the host control module 1-12 receives the manual control signal, it is necessary to judge the manual control signal to determine whether the host unit 1-1 needs to forward the manual control signal 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] Further, the two host units (including Figure 1 1-1 and 1-2) adopt mutual inspection and BIT technology, interact through the transmission bus, and can send main monitoring signals and auxiliary monitoring signals to each other in real time, and monitor whether there are faults in the two host units 1-1 in real time; when the two host units 1-1 perform mutual inspection, when one of the host units 1-1 does not receive the main monitoring signal sent by the other party within the set time, it means that the host unit 1-1 detects that the safety function part (i.e., the function related to the opening and closing of the platform door) of the other host unit 1-2 is faulty, and the platform control host 1 enters a safe state to improve its safety and prevent the platform control host 1 from forwarding erroneous commands to the first electronic control unit 2 or the second electronic control unit 3. When one of the host units 1-1 does not receive the auxiliary monitoring signal sent by the other party within the set time, it means that the host unit 1-1 detects that the non-safety function part (i.e., the function unrelated to the opening and closing of the platform door) of the other host unit 1-2 is faulty, and the control signal is forwarded by the normal host unit to improve the availability of the platform control host 1.

[0128] Furthermore, the two host units 1-1 together constitute a heterogeneous structure of the station control host 1, which prevents the station control host 1 from forwarding an error in 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 the same (that is, 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 station 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, Figure 2 As shown, the platform door signal transmission system adopts two platform control hosts 1, so that the two platform control hosts 1 form a redundant structure.

[0130] The first electronic control unit 2 can manually monitor and control the opening and closing of the platform door. The first electronic control unit 2 performs two-way signal transmission with the platform control host 1. When the data is downlinked, the first electronic control unit 2 can receive and process the first control signal forwarded by the signal processor; when the data is uplinked, the first electronic control unit 2 can send the manual control signal it generates to the platform control host 1. The first electronic control unit can generate a non-safety output signal according to the first control signal to update the operating status of the manual control panel; the first electronic control unit generates the manual control signal according to the safety acquisition signal. The first electronic control unit 2 performs two-way signal transmission with the manual control panel. When the data is downlinked, the first electronic control unit 2 sends a non-safety output signal to the manual control panel; when the data is uplinked, the first control unit can receive the safety acquisition signal sent by the manual control panel. Among them, 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 12-1 and 2-2), the two first logic units 2-1 are connected by a transmission bus. Each first logic unit 2-1 performs two-way signal transmission with the platform control host 1. When the data is downlink, each first logic unit 2-1 can receive and process the first control signal sent by the platform control host 1, and perform logical calculation to generate a non-safe output signal; when the data is uplink, each first logic unit 2-1 sends the manual control signal it generates to the platform control host 1. Each first logic unit 2-1 can generate a non-safe output signal according to 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 according to the safety acquisition signal. Each first logic unit 2-1 performs two-way signal transmission with the manual control panel. When the data is downlink, each first logic unit 2-1 can send a non-safe output signal to the manual control panel, update the monitoring status of the platform door of the terminal device 1 in real time, and enable the manual control panel to generate a safety acquisition signal; and when the data is uplink, the first control unit can receive the safety acquisition signal sent by the manual control panel, and generate a manual control signal according to 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 signal 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 performs two-way signal transmission with the signal processor. When data is downlinking, the first communication module 2-11 can receive the first control signal forwarded by the station control host 1; when data is uplinking, the first communication module 2-11 sends the artificial control signal generated by it to the station control host 1. The first communication module 2-11 performs two-way signal transmission 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 receive the non-safety output signal generated by the first control module 2-12. The first communication module 2-11 performs two-way signal transmission with the first acquisition and drive module 2-13. When data is downlinking, the first communication module 2-11 can forward the non-safety output signal to the first acquisition and drive module 2-13; when data is uplinking, the first communication module 2-11 can receive the safety 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), so that the first electronic control unit 2 allows manual control of the opening and closing of the platform door and generates manual control signals. The first control module 2-12 performs two-way signal transmission with the first communication module 2-11. When data is downlinked, the first control module 2-12 can receive the first control signal forwarded by the first communication module 2-11, generate a non-safety output signal according to the first control signal sent by the host communication module 1-11, and control the operating status of the terminal device 1 (i.e., the display status of the manual control panel); and when data is uplinked, the first control module 2-12 can generate a manual control signal according to the safety acquisition signal sent by the manual control panel.

[0136] The first acquisition and drive module 2-13 performs two-way signal transmission with the first communication module 2-11. When data is downlinking, the first acquisition and drive module 2-13 can receive the non-safe output signal forwarded by the first communication module 2-11. When data is uplinking, the first acquisition and drive module 2-13 forwards the safe acquisition signal to the first communication module 2-11. The first acquisition and drive module 2-13 performs two-way signal transmission with the terminal device 1. When data is downlinking, the first acquisition and drive module 2-13 can forward the non-safe output signal to the terminal device 1 (i.e., the manual control panel), control the terminal device 1 to execute the non-safe output signal, and enable the terminal device 1 to generate a safe acquisition signal; at the same time, when data is uplinking, the first acquisition and drive module 2-13 can receive the safe acquisition signal generated by the terminal device 1.

[0137] Furthermore, the two first logic units 2-1 adopt mutual inspection and BIT technology, interact through the transmission bus, and can send main monitoring signals and auxiliary monitoring signals to each other in real time, and monitor whether the two first logic units 2-1 have faults in real time. When the two first logic units perform mutual inspection, when one of the first logic units 2-1 does not receive the main monitoring signal sent by the other party within the set time, it means that the first logic unit 2-1 detects that the safety function of the other first logic unit 2-2 is partially faulty. At this time, the first electronic control unit 2 enters a safe state to improve its safety and prevent the first electronic control unit 2 from sending erroneous execution instructions to the terminal device 1; when one of the first logic units 2-1 does not receive the auxiliary monitoring signal within the set time, it means that the first logic unit 2-1 detects that the non-safety function of the other first logic unit 2-2 is partially faulty, and the normal first logic unit controls the input, operation and output of the first logic unit to improve 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, and the signals generated by the two can be compared. 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 the non-safety output signal to the terminal device 1 to update the monitoring status of the platform door by the terminal device 1; 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 a safe output signal. When the manual control signals generated by the two first logic units are the same (the control signals are both safety 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 signal.

[0139] When the first electronic control unit 2 is required to manually operate the platform door switch, 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 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-safe output signal according to the first control signal. The non-safe output signals generated by the two first logic units 2-1 are compared. When the non-safe output signals generated by the two are consistent, the non-safe output signal is sent to the first acquisition and drive module 2-13 through the first communication module 2-11, and the first acquisition and drive module 2-13 outputs the non-safe output signal to the terminal device 1, controls the terminal device 1 to execute the non-safe output signal, and completes the update of the platform door monitoring status in the terminal device 1. The operator can control the opening and closing state of the platform door through the terminal device 1 according to the monitoring status of the platform door of the terminal device 1, so that the manual control panel generates a safety acquisition signal.

[0140] At the same time, the first acquisition and drive 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, and then the first communication module 2-11 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 according to the safety acquisition signal. Comparing the manual control signals of the two first logic units 2-1, when the manual control signals of the two first logic units 2-1 are inconsistent, the first electronic control unit 2 enters the safe state; when 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. Furthermore, 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 opening and closing of the platform door is controlled by the manual control panel. At this time, the platform control host 1 forwards the safety command to the second electronic control unit 3, which further controls the opening and closing of the platform door; when the manual control signal is a non-safety command, it means that no operation is performed on the manual control panel. At this time, the platform control host 1 forwards the non-safety command to the signal 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 and the platform control host 1 have two-way signal transmission. When data is downlinked, the second electronic control unit 3 can receive and process the second control signal or safety command sent by the signal processor, and generate a first output signal and a second output signal according to the second control signal or safety command; when data is uplinked, the second electronic control unit 3 can send a platform door status message to the platform control host 1. The second electronic control unit 3 and the platform door device have two-way signal transmission. When data is downlinked, the second electronic control unit 3 can send a first output signal and a second output signal to the platform door device; when data is uplinked, the second electronic control unit 3 can receive a platform door status message sent by the platform door device.

[0143] Wherein, the platform door equipment includes: gate lock (i.e. Figure 1 The terminal device 2) and the platform motor; the platform door status message includes: a gate lock status message reflecting the operating status of the gate lock and a motor status message reflecting the operating status of the platform motor; the first output signal is used to control the operation of the gate lock, and the second output signal is used to control the operation of the platform motor.

[0144] The second electronic control unit 3 includes: 2 second logic units (including Figure 1 3-1 and 3-2), the signal transmission is transmitted through the transmission bus. Each of the second logic units 3-1 transmits signals bidirectionally with the platform control host 1. When the data is downlink, each of the second logic units 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; when the data is uplink, each of the second logic units 3-1 can send a platform door status message to the signal processor. Each of the second logic units 3-1 transmits signals bidirectionally with the gate lock. When the data is downlink, each of the second logic units 3-1 can send a first output signal to the gate lock to control the operation of the gate lock, and the gate lock generates a gate lock status message; when the data is uplink, each of the second logic units 3-1 can receive the gate lock status message generated by the gate lock. Each of the second logic units 3-1 has bidirectional signal transmission with the platform motor. When data is downlink, 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 enable the platform motor to generate a motor status message. When data is uplink, 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 drive module 3-13 and a drive module 3-14.

[0146] The second communication module 3-11 and the station control host 1 have two-way signal transmission. When data is downlinked, the second communication module 3-11 can receive the second control signal or safety command forwarded by the station control host 1; when data is uplinked, the second communication module 3-11 can forward the gate lock status message and the motor status message to the station control host 1; the second communication module 3-11 and the second control module 3-12 have two-way signal transmission. The second communication module 3-11 can forward the second control signal or safety command to the second control module; the second communication module 3-11 can receive the first output signal and the second output signal generated by the second control module 3-12. The second communication module 3-11 and the second acquisition and drive module 3-13 have two-way signal transmission. When data is downlinked, the second communication module 3-11 can forward the first output signal to the second acquisition and drive module 3-13; when data is uplinked, the second communication module 3-11 can receive the gate lock status message forwarded by the second acquisition and drive module 3-13. The second communication module 3-11 and the driving module 3-14 perform bidirectional signal transmission. When data is downlink, the second communication module 3-11 can forward the second output signal to the driving module 3-14; when data is uplink, the second communication module 3-11 can receive the motor status message forwarded by the driving module 3-14.

[0147] The second control module 3-12 and the second communication module 3-11 perform two-way signal transmission, and can receive and calculate the second control signal and safety command forwarded by the second communication module 3-11 to generate a first output signal and a 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 acquisition and drive module 3-13 performs two-way signal transmission with the terminal device 2. When data is downlink, the second acquisition and drive module 3-13 can send a first output signal to the gate lock to control the operating status of the gate lock and enable the gate lock to generate a gate lock status message; and when data is uplink, the second acquisition and drive module 3-13 sends the gate lock status message to the signal system through the second communication module 3-11.

[0149] The driving module 3-14 and the platform motor have bidirectional signal transmission. When data is downlink, the second acquisition and driving 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 state of the platform motor, and enables the platform motor to generate a motor status message; and when data is uplink, the driving 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 auxiliary monitoring signals to each other in real time, so as to monitor in real time whether there are any faults in the two second logic units 3 - 1.

[0151] When the two second logic units 3-1 perform mutual inspection, if one of the second logic units 3-1 fails to receive the main monitoring signal sent by the other party within the set time, it means that the second logic unit 3-1 detects that the safety function of the other second logic unit 3-2 is partially faulty. At this time, the second electronic control unit 3 will enter a safe state to improve its safety and prevent the second electronic control unit from sending erroneous execution instructions to the terminal device 2 and the platform motor; when one of the second logic units 3-1 fails to receive the secondary monitoring signal sent by the other party within the set time, it means that the second logic unit 3-1 detects that the non-safety function of the other second logic unit 3-2 is partially faulty, and the normal second logic unit controls the input, operation and output of the second electronic control unit to improve 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, which can generate the first output signal and the second output signal respectively, and perform data exchange through the transmission bus. Comparing the first output signal and the second output signal 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, one of the second logic units 3-1 sends the first output signal and the second output signal to the terminal device 2 and the platform motor respectively; otherwise, the second electronic control unit 3 will enter a safe state.

[0153] When the second electronic control unit 3 is required to automatically control the platform door switch, 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. Compare the first output signal and the second output signal 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 sends it 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 sends it to the platform motor to drive the platform motor to operate; the gate lock (terminal device 2) and the platform motor work together to drive the sliding switch of the platform door. At the same time, 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; the gate lock status message and the motor status message are both sent to the platform control host 1 through the second communication module 3-11, and feedback is given to the platform control host 1 whether the platform door is successfully opened and 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 the number of platform door devices and the number of manual control panels as required, thereby improving the applicability of the platform door signal transmission system in multiple scenarios. In addition, 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, which facilitates the fault handling and maintenance of the platform door signal transmission system and improves the fault handling efficiency of the platform door signal transmission system.

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

[0156] The signal system can generate a first control signal or a second control signal according to the platform door status message, and perform two-way signal transmission with the platform door signal transmission system. When data is downlink, the signal system can send the first control signal or the second control signal to the platform door signal transmission system; when data is uplink, the signal system can receive the platform door status message sent by the platform door signal transmission system.

[0157] The manual control panel can generate a safety acquisition signal by updating the operating status of the manual control panel according to the non-safety output signal and manually controlling the operating status of the platform door equipment. The manual control panel and the platform door signal transmission system can perform two-way signal transmission. When data is downlinked, the manual control panel can receive the non-safety output signal sent by the platform door signal transmission system; when data is uplinked, the manual control panel can send a safety acquisition signal to the platform door signal transmission system.

[0158] The platform door equipment includes: a gate lock and a platform motor, and the opening and closing states of the platform door are controlled by the coordinated operation of the gate lock and the platform motor.

[0159] The gate lock changes the operating state according to the first output signal and generates a gate lock state message. The gate lock can perform two-way signal transmission with the platform door signal transmission system. When data is downlinked, the gate lock can receive the first output signal sent by the platform door signal transmission system; when data is uplinked, the gate lock can send a gate lock state message to the platform door signal transmission system.

[0160] The platform motor can change the running state according to the second output signal to generate a motor status message. The platform motor and the platform door signal transmission system can perform two-way signal transmission. When data is downlinked, the platform motor can receive the second output signal sent by the platform door signal transmission system; when data is uplinked, 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 door system also includes: an integrated monitoring system, which transmits signals with the platform control host 1 and can record all signals sent by the platform control host 1, thereby realizing the monitoring of the operating status of the platform door signal transmission system.

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

[0163] When the platform door is opened and closed successfully, the signal system sends a second control signal to the platform control host 1, and the platform control host 1 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 door device, and sends the platform door status message fed back by the platform door device 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 collection signal fed back by the manual control panel, and then sends the manual control signal to the signal processor.

[0165] Furthermore, when the platform door fails to open or close and manual operation is required to control the opening or closing of the platform door, the operator operates the manual control panel, and 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 sent by the manual control panel, and sends the safety command to the platform control host 1; the platform control host 1 sends the safety command to the second electronic control unit 3, and the second electronic control unit 3 controls the opening or closing of the platform door device. When the platform door fails to open or close and no further operation is required on the platform door, no operation is required on the manual control panel at this time, and the second electronic control unit 3 receives the safety acquisition signal generated by the manual control panel, and generates a non-safety command based on the safety acquisition signal sent by the manual control panel, and sends the non-safety command to the signal system through the platform control host 1.

[0166] Embodiment 1

[0167] like Figure 2 As shown in the figure, under normal circumstances, the platform doors can be opened and closed automatically when the train enters and leaves the platform:

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

[0169] The signal system sends the control signal (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 signal system recognizes that the platform door is successfully opened or closed according to the platform door status message sent by the platform door device, the signal system sends a "second control signal" to the platform control host 1, so that the platform door automatically opens or closes according to the "second control signal";

[0170] Step A2: the station controls the host to forward the control signal.

[0171] Each host communication module 1-11 in the station control host 1 receives the "second control signal" and forwards the "second control signal" to its corresponding host control module 1-12, and the host control module 1-12 determines 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] At the same time, the control signals forwarded by the two host units 1-1 in the station control host 1 are compared. When the control signals forwarded by the two host units 1-1 are both "second control signals", one of the host units 1-1 in the station control host 1 sends the "second control signal" to the second electronic control unit 3; if the control signals forwarded by the two host units 1-1 are inconsistent, the station control host 1 enters a safe state and stops forwarding any commands.

[0173] In a preferred embodiment, the platform door system uses two platform control hosts 1. When one platform control host 1 enters the security station, 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 the corresponding third control unit; the third control unit generates a first output signal and a 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 signals generated by the two second logic units 3-1 are consistent and the second output signals are also consistent, one of the second logic units 3-1 sends the first output signal and the second output signal to the terminal device 2 (gate lock) and the platform motor respectively; otherwise, the second electronic control unit 3 will be controlled to enter a safe state and will no longer send any signal to the terminal 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 through the second communication module 3-11, and then sends it to the terminal device 2 (gate lock); at the same time, the second output signal is sent to the drive module 3-14 through the second communication module 3-11, and then sent to the platform motor. The gate lock and the platform motor work together to realize the opening and closing of the platform door.

[0178] Step A4: the terminal device 2 and the platform motor feed back 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; and the second electronic control unit 3 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 feedback to the external system whether the platform door is successfully opened and closed automatically.

[0180] Embodiment 2

[0181] like Figure 2 As shown in the figure, when the train enters and leaves the platform, the platform door cannot be opened and closed automatically:

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

[0183] The signal system sends 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 signal system recognizes that the platform door fails to open or close according to the platform door status message, the signal system sends a "first control signal" to the platform control host 1 to control the opening or closing state of the platform door through the manual control panel.

[0184] Step B2: the station controls the host to forward the control signal.

[0185] Each host communication module 1 - 11 in the station control host 1 receives the “first control signal”, and forwards the “first control signal” to its corresponding host control module 1 - 12 , and further sends it to the first electronic control unit 2 .

[0186] At the same time, 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 door system uses two platform control hosts 1. When one platform control host 1 enters the security station, the other platform control host 1 repeats this step.

[0188] Step B3: the first electronic control unit updates the operation 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 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 first logic units are consistent, one of the first logic units 2-1 sends the non-safety output signal to the terminal device 1 (manual control panel); otherwise, the first electronic control unit 2 will be controlled to enter a safe state and no signal will be sent 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 sends it to the manual control panel, updates the monitoring status of the platform door of 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 door equipment feeds back the platform door status message to the signal system.

[0193] The terminal device 1 updates the monitoring status of the platform door, and the operator sends a safety collection signal reflecting the state of the manually operated platform door to the first electronic control unit 2 through the operation of the 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 the corresponding first control modules 2-12 respectively, and the first control module 2-12 generates an artificial control signal (ie, a safety command or a non-safety command) according to the safety acquisition signal.

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

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

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

[0198] Each host communication module 1-11 in the platform control host 1 receives the "manual control signal" and forwards the "manual control signal" to its corresponding host control module 1-12, and the host control module 1-12 controls the transmission of the manual control signal. At this time, when the "manual control signal" received by the host communication module 1-11 is a "safety command", it means that a manual instruction is issued to control the automatic opening and closing of the platform door, and the "second control signal" needs to be sent to the second electronic control unit 3; when the "manual control signal" received by the host communication module 1-11 is a "non-safety command", it means that the manual control panel has not been operated, and the "non-safety command" will be sent to the signal system to feedback the operating status of the manual operation panel to the signal system.

[0199] At the same time, the artificial control signals forwarded by the two host units 1-1 in the platform control host 1 are compared. When the "artificial control signals" forwarded by the two host units 1-1 are consistent (that is, both are "safety commands" or "non-safety commands"), it means that the "artificial control signal" generated by the platform control host 1 is correct; if the "artificial 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 in the platform control host 1 forwards the "safety command" to the second electronic control unit 3, and repeats steps A3-A4 in Example 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 signal system.

[0201] In summary, a platform door signal transmission system of the present invention utilizes a data transmission link to replace the existing hard-wired cable single-channel transmission, thereby avoiding mixed line and mixed power accidents caused by wiring errors during the installation process; and utilizes cross-check technology and BIT technology to realize hierarchical classification processing of safety functions related to platform door switches and non-safety functions unrelated to platform door switches, thereby improving the safety and availability of the platform door system.
