[0021] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] Please refer to Figure 1 , Figure 1 A schematic flow chart of a method for identifying abnormal door opening of a rail vehicle provided by the present invention.

[0023] The present invention provides a method for identifying abnormal door opening of a rail vehicle, comprising: 101: Obtain door data; the door data includes a door opening button signal, a train speed, a zero speed signal, a door opening signal, a door opening authorization signal, a door opening enabling signal and a door lock status signal; 102: According to the door opening button signal, the train speed, the door opening enabling signal, the door opening authorization signal and the door opening signal, a preset door opening condition back-calculation algorithm is used to identify the door opening abnormality condition to obtain a condition identification result; 103: When the condition recognition result is that the preset door opening condition is met, the number of doors that are not opened normally is counted according to the door lock state signal to obtain an abnormal statistical result; 104: Determine the final door opening abnormality recognition result according to the condition recognition result, the abnormality statistical result and the zero speed signal.

[0024] In this embodiment, the data acquisition module is responsible for the communication with the vehicle network, and realizes the acquisition of door data from the door-related data in the network; the door data may specifically include the door opening button signal, train speed, zero speed signal, door opening signal, door opening authorization signal, door opening activation signal and door lock status signal. After the driver operates the door opening button, the condition recognition module sorts out the situation where the door does not move, combines the door opening button action, door opening authorization, vehicle zero speed and other necessary conditions that must be met for the door opening action of the entire train, adopts the preset door opening condition reverse algorithm, constructs the door opening abnormal condition recognition logic, directly analyzes and locates the cause of the abnormality, and obtains the condition recognition result. When the condition recognition result is to meet the preset door opening condition, there are some doors that are not moved due to the door itself. The abnormal statistics module sorts out the door status according to the door lock status signal, and counts the car number-door number and the number of doors for the doors that have not moved (not opened normally), and obtains the abnormal statistical results. Finally, the result determination module will combine the condition recognition result, the abnormal statistical result and the zero speed signal to determine the final door opening abnormal recognition result.

[0025] It should be noted that: The door opening button signal is a signal that indicates whether the driver in the driver's cab operates the door opening button, for example, including 01A side door opening button 1 signal, 01A side door opening button 2 signal, 01B side door opening button 1 signal, 01B side door opening button 2 signal, 08A side door opening button 1 signal, 08A side door opening button 2 signal, 08B side door opening button 1 signal and 08B side door opening button 2 signal.

[0026] The zero speed signal is a vehicle stop signal and is given when the vehicle speed is lower than a certain speed.

[0027] The door opening signal is a signal indicating whether the door is open, for example including 01A side door opening 1 signal, 01A side door opening 2 signal, 01B side door opening 1 signal, 01B side door opening 2 signal, 08A side door opening 1 signal, 08A side door opening 2 signal, 08B side door opening 1 signal and 08B side door opening 2 signal.

[0028] The zero speed signal and the door opening signal are transmitted to the door controller for door opening drive control.

[0029] The door opening authorization signal is a signal indicating whether the door opening is authorized.

[0030] The door opening enable signal is a signal indicating whether the door opening enable relay is turned on, for example, including the 01A side door opening enable signal, the 01B side door opening enable signal, the 08A side door opening enable signal and the 08B side door opening enable signal.

[0031] The door lock state signal is a signal indicating whether the door is in a locked state.

[0032] Of course, the door data may also include column number, vehicle number, door number and time, and the present invention does not make any special limitation here.

[0033] The present invention does not require additional equipment, that is, it is implemented on the basis of the existing collected data of the door controller. The invention has low implementation cost and is easy to apply in engineering. By identifying abnormal door opening conditions, the abnormal conditions that cause abnormal door opening can be directly located, thereby improving the efficiency of fault analysis of abnormal door opening. It can directly realize statistics on doors that do not open normally, and can replace the existing method of manually searching and counting the location of faulty doors through the MON screen, thereby reducing the workload of maintenance personnel and improving the efficiency of repair and maintenance.

[0034] As a preferred embodiment, it also includes: storing and managing the door data, condition recognition results, abnormal statistical results and final door opening abnormality recognition results.

[0035] In this embodiment, the data management module stores and manages the door data, condition recognition results, abnormal statistical results and the final door opening abnormal recognition results, which not only helps to monitor the door status in real time, but also can be used for subsequent data analysis and fault diagnosis. At the same time, if there is an abnormal door opening situation, the located abnormal condition or the statistical abnormal door result data will be pushed to the vehicle network.

[0036] Please refer to Figure 2 , Figure 2 A schematic diagram of a specific flow chart of a method for identifying abnormal door opening of a rail vehicle provided by the present invention.

[0037] As a preferred embodiment, according to the door opening button signal, train speed, door opening enable signal, door opening authorization signal and door opening signal, a preset door opening condition reverse algorithm is used to identify the door opening abnormal condition to obtain a condition identification result, including: when the basic conditions are met and the door opening enable signal is invalid, the door opening authorization identification is performed according to the door opening authorization signal; the basic condition is that the door opening button signal is valid and the train speed is zero speed; when the door opening authorization signal is valid, the condition identification result is that the door opening enable relay is abnormal or the connection line of the relay is abnormal; when the door opening authorization signal is invalid, the door opening identification is performed according to the door opening signal to obtain a condition identification result.

[0038] In this embodiment, after receiving the door data, it is first determined whether the basic conditions for opening the door are met. The basic conditions are that the door opening button signal is valid and the train speed is zero.

[0039] In the door opening button signal judgment step, if the door opening button is pressed, the door opening button signal is valid and the train speed judgment step is executed; if the door opening button is not pressed, the door opening button signal is invalid and the door data receiving step is executed.

[0040] In the train speed judgment step, if the train speed is 0km / h, the basic conditions for opening the door are met, and the door opening activation signal judgment step is executed; if the train speed is not 0km / h, the basic conditions for opening the door are not met, and the door data receiving step is executed.

[0041] In the door opening enable signal judgment step, if the door opening enable relay is activated, the door opening enable signal is valid, and the abnormality statistics step is executed; if the door opening enable relay is not activated, the door opening enable signal is invalid, and the door opening authorization signal judgment step is executed.

[0042] In the door opening authorization signal judgment step, when the door opening authorization signal is valid, the conditional recognition result is that the door opening enabling relay is abnormal or the connection line of the relay is abnormal; when the door opening authorization signal is invalid, the door opening signal judgment step is executed, and the door opening recognition is performed according to the door opening signal to obtain the conditional recognition result.

[0043] As a preferred embodiment, the door opening button signal includes a first button signal and a second button signal; when both the first button signal and the second button signal are valid, the door opening button signal is valid.

[0044] In this embodiment, the received 01A side door open button 1 signal (first button signal) and 01A side door open button 2 signal (second button signal), 01B side door open button 1 signal and 01B side door open button 2 signal, 08A side door open button 1 signal and 08A side door open button 2 signal, 08B side door open button 1 signal and 08B side door open button 2 signal are respectively calculated "AND" to obtain the status signal of whether the 01A side door open button, 01B side door open button, 08A side door open button, and 08B side door open button are actuated; when the first button signal and the second button signal are both valid, the door open button signal is valid.

[0045] As a preferred embodiment, the door opening signal includes a first opening signal and a second opening signal; when both the first opening signal and the second opening signal are valid, the door opening authorization signal is valid; when the door opening authorization signal is invalid, the door opening is identified according to the door opening signal to obtain a conditional identification result, including: when the door opening authorization signal is invalid, the door opening is identified according to the first opening signal; when the first opening signal is valid, the conditional identification result is that the second opening signal is transmitted abnormally; when the first opening signal is invalid, the conditional identification result is that the first opening signal is transmitted abnormally.

[0046] In this embodiment, four groups of door opening authorization signals are obtained by "ANDing" the 01A side door opening 1 signal (the first opening signal) and the 01A side door opening 2 signal (the second opening signal), the 01B side door opening 1 signal and the 01B side door opening 2 signal, the 08A side door opening 1 signal and the 08A side door opening 2 signal, and the 08B side door opening 1 signal and the 08B side door opening 2 signal; when both the first opening signal and the second opening signal are valid, the door opening authorization signal is valid.

[0047] When the door opening authorization signal is invalid, the door opening signal determination step is performed. If the first opening signal is valid, the second opening signal is invalid, and the conditional identification result is that the second opening signal is abnormally transmitted; if the first opening signal is invalid, the conditional identification result is that the first opening signal is abnormally transmitted.

[0048] As a preferred embodiment, the preset door opening condition is that the basic conditions are met and the door opening enable signal, the door opening authorization signal and the door opening signal are all valid.

[0049] Considering that the train doors meet the basic conditions for opening the doors and the door opening activation signal, door opening authorization signal and door opening signal are all valid, but it is still possible that the doors cannot be opened normally due to their own reasons, in this embodiment, the number of doors that are not opened normally is counted according to the door lock status signal. Specifically, the number of doors whose door lock status signals are invalid (opened) is counted; if the number of doors that have been opened is the total number of doors (for example, the total number of doors on one side of the vehicle is 40), the step of receiving door data is executed. If the number of doors that have been opened is not zero and is not the total number of doors, the vehicle number-door number summary table corresponding to the valid door lock status signal (not opened normally) is pushed to the train network. If the number of doors that have been opened is zero, it means that all doors have not been opened normally, and the zero speed signal judgment step is executed.

[0050] Of course, in order to ensure that the door control-related systems have enough time to process requests and return status, an appropriate system response and buffer time can be set, such as a 6-second delay. By considering the signal transmission delay and the differences in the actions of each door, a certain delay time is given to avoid misjudgment. The signal delay rows of specific projects can be combined for statistics and updates, and the present invention is not particularly limited here.

[0051] As a preferred embodiment, the final door opening abnormality identification result is determined according to the condition identification result, the abnormality statistical result and the zero-speed signal, including: when the condition identification result is that the preset door opening condition is met and the abnormality statistical result is that the number of doors that are not opened normally is greater than zero, zero speed identification is performed according to the zero-speed signal; when the zero-speed signal is valid, the final door opening abnormality identification result is that the connecting line that transmits the door opening enable signal is abnormal; when the zero-speed signal is invalid, the final door opening abnormality identification result is that the zero-speed signal relay is abnormal or the signal line that transmits the zero-speed signal is abnormal.

[0052] Considering that the train doors meet the basic conditions for opening the doors and the door opening enable signal, door opening authorization signal and door opening signal are all valid, but all the doors still cannot be opened normally, in this embodiment, zero speed identification is performed according to the zero speed signal. If the zero speed signal is valid, the final door opening abnormality identification result is that the connection line transmitting the door opening enable signal is abnormal; if the zero speed signal is invalid, the final door opening abnormality identification result is that the zero speed signal relay is abnormal or the signal line transmitting the zero speed signal is abnormal.
