[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] like figure 1 As shown, the platform door self-awakening detection system in this embodiment includes a host computer 1 , a platform door central control panel 2 , and a self-awakening detection unit 3 .
[0026] The upper computer 1 is set in the control center, and the control center usually arranges staff to supervise various operating conditions in the entire station.
[0027] The platform door central control panel 2 is arranged in the equipment room. The platform door central control panel 2 in this embodiment can adopt the PSC system in the prior art. The platform door central control panel 2 communicates with the platform door through the platform door system internal bus. Each component of the platform door is electrically connected, so that the condition of the components of the platform door can be detected, and at the same time, the movement of the platform door can be controlled, so that the static detection and dynamic detection of each component of the platform door can be realized.
[0028] The self-wake-up detection unit 3 includes a control device 31 , a communication device 32 electrically connected to the control device 31 , a trigger device 33 capable of generating a self-wake-up trigger signal, and a video monitoring device 34 electrically connected to the control device 31 .
[0029] The control device 31 communicates with the upper computer 1 and the central control panel 2 of the platform door respectively through the communication device 32 . The triggering device 33 is electrically connected to the triggering signal terminal of the central control panel 2 of the platform door. The triggering device 33 in this embodiment includes a timing triggering device 331 electrically connected to the control device 31, a simulator triggering device 332, and a remote wireless communication triggering device 333, and the remote wireless communication triggering device 333 is also communicatively connected with the upper computer 1 . The timing trigger device 331 can automatically time the timing and send the trigger signal at the set time. The simulator can send a trigger signal through a hard-wired connection according to the control command. The simulator usually uses a relay. According to the control command, the relay sends high and low level signals to form a trigger signal. The remote wireless communication triggering device 333 can form a trigger signal according to the received wireless signal, and the remote wireless communication triggering device 333 can also directly receive the control command of the upper computer 1, when the upper computer 1 sends a platform to the remote wireless communication triggering device 333 When the door self-awakening detection command is issued, the remote wireless communication trigger device 333 can receive the signal sent by the host computer 1 and send a trigger signal to the platform door central control panel 2, and then trigger the platform door central control panel 2 to perform platform door self-awakening detection.
[0030] The video monitoring device 34 includes a video acquisition device arranged in the platform area and a video acquisition device arranged in the track area, that is, cameras are respectively installed in the platform area and the track area. In this way, it is convenient to collect images in the platform area and the track area, and it is convenient to check whether there are people inside and outside the platform before dynamic detection, so as to ensure the safety during the detection process.
[0031] The self-awakening detection method of the platform door in the present invention is: according to the operation schedule, before the set time period before the main line operation, the control device 31 controls the trigger device 33 to send a self-awakening trigger signal to the central control panel 2 of the platform door, and the platform The door central control panel 2 starts the self-awakening detection work according to the self-awakening trigger signal, and then realizes the static detection and dynamic detection of the platform door.
[0032]There are three trigger devices 33 in this embodiment. In order to ensure the accuracy of the self-awakening detection results, each trigger device 33 is controlled to trigger the platform door central control panel 2 to perform a self-awakening of the platform door each time the platform door self-awakening detection is performed. detection. In order to better realize the sequential self-wake-up triggers of the three trigger devices 33, in this embodiment, the control device 31 sets the work priorities of the timing trigger device 331, the simulator trigger device 332, and the remote wireless communication trigger device 333, and the timing trigger device 331. The simulator trigger device 332 and the remote wireless communication trigger device 333 sequentially trigger the platform door central control panel 2 to start the self-awakening detection work of the platform door according to the corresponding priority, wherein the trigger device 33 of the current priority triggers the self-awakening detection work of the platform door. The wake-up detection work end signal or the failure signal of the trigger device 33 is used as the trigger signal for the control device 31 to control the next priority trigger device 33 to work.
[0033] In order to ensure that the platform door has no faults and ensure the safety of rail transit, the platform door is usually tested multiple times to ensure the accuracy of the test results and ensure the safe operation of the platform door. In this way, when the platform door central control panel 2 controls the platform door to perform self-awakening detection work, the number of times the platform door central control panel 2 normally completes the self-awakening detection work of the platform door is cumulatively counted, and each trigger device 33 triggers the platform door in turn. Under the condition that the self-awakening detection work of the platform door is completed at least once after the control panel 2, if the number of self-awakening detection work of the platform door does not reach the set number of times, the control device 31 can trigger the central control panel 2 of the platform door to complete normally The trigger device 33 with the lowest priority for the self-awakening detection work of the platform door continues to trigger the central control panel 2 of the platform door to perform the self-awakening detection work of the platform door until the central control panel 2 of the platform door normally completes the self-awakening detection work of the platform door. When the set number of times is reached, then the number of times the platform door central control panel 2 normally completes the self-awakening detection work of the platform door is cleared.
[0034] If the timing trigger device 331 fails, then send a fault signal to the control device 31, and the control device 31 controls the simulator trigger device 332 to send a trigger signal for the self-awakening detection of the platform door to the central control panel, if the simulator trigger device 332 can normally send the trigger signal , then the central control panel controls the platform door to perform self-awakening detection according to the trigger signal. After the central control panel normally completes the current self-awakening detection work of the platform door, the count is 1, and the end signal is sent to the control device 31 at the same time. The control device 31 further controls the remote wireless communication trigger device 333 to send a trigger signal for the self-awakening detection of the platform door. If the simulator trigger device 332 can normally send the trigger signal, the central control panel controls the platform door to perform self-awakening detection according to the trigger signal. After the control panel normally completes the current self-awakening detection work of the platform door, the count is 2, and the end signal is sent to the control device 31 at the same time. In this embodiment, the number of times is set to 3, so that the control device 31 continues to control the remote wireless communication trigger device 333 to send the trigger signal for the self-awakening detection of the platform door. If the simulator trigger device 332 can normally send the trigger signal, the central control panel will trigger The signal controls the platform door to perform self-awakening detection. After the central control panel normally completes the current self-awakening detection of the platform door, the count is 3, so the set number of times has reached 3, and then the central control panel 2 of the platform door is normally completed. The number of self-awakening detection work of the platform door is cleared.
[0035] Among them, the platform door central control panel 2 mainly checks and confirms the signals of interface components such as electromagnetic locks, motors, travel switches, and indicator lights one by one in the door machine system, and confirms whether the peripheral control components are faulty. ; At the same time, the storage circuit, clock circuit, and power circuit inside the controller of the door machine control system are checked for status, and the working status of the internal logic control board and safety relay of the door machine control system is checked to determine whether they are in a normal working state; Check and confirm the status of external power supply voltage, system output voltage and current, whether they are within the normal working range; each door control unit sends communication link test information to the monitoring system, and when the communication status is confirmed to be normal, it sends each door unit to the monitoring system self-test information.
[0036] The self-inspection fault information processing method in the static detection process of the platform door is as follows: the self-inspection fault information is classified into key fault information and non-critical fault information. For non-critical failure information, such as sporadic communication interruption, the failure storage will not affect the entry into the dynamic test. For key failure information, such as abnormal power supply voltage, motor failure, relay failure, etc., the system restarts and recovers first. If the failure cannot be recovered, an alarm message is sent to the upper computer 1 immediately, and maintenance personnel are requested to troubleshoot. After the fault is repaired, proceed to the next step of testing.
[0037] In order to ensure safety during the dynamic detection process, after the platform door central control panel 2 has completed the static detection of the platform door, the self-awakening dynamic detection of the platform door can be performed by the following three methods.
[0038] 1) Send the current static detection completion signal to the control device 31 of the self-awakening detection unit 3, and the self-awakening detection unit 3 obtains the image information inside and outside the platform collected by the video monitoring device 34, and then judges whether the train is moving in the yellow line after the withdrawal on the platform Whether there are people in the track area of the platform, when it is judged that there are no people in the yellow line on the platform and in the track area where the train travels, a dynamic detection command is sent to the central control panel 2 of the platform door directly according to the judgment result, The platform door central control panel 2 controls the dynamic detection of the platform door according to the dynamic detection command. This method can effectively improve the detection efficiency.
[0039] 2) When the control device 31 of the wake-up detection unit judges that there is no personnel in the retreat yellow line on the platform and in the track area where the train travels, the control device 31 sends a platform door dynamic detection authorization request signal to the upper computer 1, and the upper computer 1 After machine 1 receives the platform door dynamic detection authorization request signal, it notifies the staff of the control center to perform the authorization operation.
[0040] The staff of the control center checks the image information inside and outside the platform transmitted by the control device 31 in real time, and after confirming that there is no human activity in the retreat yellow line on the platform or in the track area where the train runs, they control it through the upper computer in one direction. The device 31 sends a dynamic platform door dynamic detection authorization signal, and the control device 31 sends a dynamic detection command to the platform door central control panel 2 after receiving the platform door dynamic detection authorization signal, and the platform door central control panel 2 controls the platform door according to the dynamic detection command. Dynamic detection. This method can better ensure the security of dynamic detection.
[0041] 3) After the platform door central control panel 2 completes the static detection of the platform door, it sends the current static detection completion signal to the control device 31 of the self-awakening detection unit 3, and after the control device 31 receives the current static detection completion signal, Send the platform door dynamic detection authorization request signal to the upper computer 1, and the upper computer 1 will notify the staff of the control center to perform the authorization operation after receiving the platform door dynamic detection authorization request signal.
[0042] The staff of the control center checks the image information inside and outside the platform transmitted by the control device 31 in real time, and after confirming that there is no human activity in the retreat yellow line on the platform or in the track area where the train runs, they control it through the upper computer in one direction. The device 31 sends a dynamic platform door dynamic detection authorization signal, and the control device 31 sends a dynamic detection command to the platform door central control panel 2 after receiving the platform door dynamic detection authorization signal, and the platform door central control panel 2 controls the platform door according to the dynamic detection command. Dynamic detection. This method can take into account the detection efficiency and the security of dynamic detection.
[0043] In the aforementioned method, the existing image detection method can be used to detect whether there are people in the retreating yellow line on the platform or in the track area where the train travels.
[0044] For the fault information detected during the self-awakening dynamic detection process of the platform door, the fault information is classified into critical fault information and non-critical fault information. For non-critical fault information, such as sporadic communication interruption, fault storage is performed. For key fault information, such as abnormal door opening and closing speed, abnormal door opening and closing time, etc., an alarm message is sent to the upper computer 1 immediately, and maintenance personnel are requested to handle the fault. After the fault repair is completed, the door opening and closing test will be performed for a set number of times until all door units open and close normally to ensure normal operation. If there are structural reasons such as the door body, when the door cannot be opened and closed, it is necessary to notify the station staff in time to isolate the door unit, and take temporary measures to remind passengers to wait for the other door unit, and then resume processing after the night is out of service.
[0045] After completing the self-awakening detection work of the platform door, the detection result information of the platform door will be stored in the control device 31 of the self-awakening detection unit 3. The control device 31 of the detection unit 3 sends an inquiry request, and then the control device 31 of the self-awakening detection unit 3 transmits the self-awakening detection result of the platform door to the upper computer 1, and the upper computer 1 controls the operation of the entire platform according to the detection result information.
[0046] In the platform door self-awakening detection system of the present invention, the platform door self-awakening detection method can be used to realize the self-awakening detection of the platform door detection before the main line operation, which reduces the risk of manual intervention and human misoperation, reduces the configuration of station staff, and reduces the operating cost. cost and improve operational efficiency. Compared with the traditional manual operation of PSL to detect the time platform door, it improves the safety and linkage test equality.
