Detailed ways

In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "first", "second", and "third" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance.

Fig. 1 shows a schematic diagram of a specific application scenario of an embodiment of the present invention, in which a rail vehicle door system is shown. The rail vehicle door system includes a plurality of zone controllers and a plurality of door leaf controllers, wherein the plurality of zone controls The device forms a regional cloud, and each door leaf controller is connected to a regional controller in the regional cloud (the regional controller can be any regional controller in the regional cloud). Each regional controller is connected to a number of regional controllers. Each door leaf controller is connected with a network communication, and each door leaf controller is connected with a door leaf drive mechanism, such as a door leaf drive motor, a door leaf drive cylinder, etc. The door leaf controller controls the door leaf according to the door leaf control instructions sent by the received area controller The operation of the driving mechanism drives the opening or closing of the door leaf of the rail vehicle. Here, it should be noted that each door leaf controller is connected to an area controller network. The door leaf controller refers to the area controller that can operate normally, and each door leaf controller is connected to an area controller network. Communication connection means that if an area controller fails, the area controller with the failure will be based on the predetermined predetermined failure rules (for example, which predetermined area controller to re-couple to, and how to select the area to reconnect to the network. The controller, or rules such as isolating the faulty regional controller from the regional cloud, etc.) is coupled to other regional controllers in the regional cloud, so as to ensure that each door leaf controller is connected to a normal operating regional controller network. In addition, as shown in Fig. 1, the regional cloud can also be connected to the cloud server and the platform controller of the rail vehicle platform corresponding to the rail vehicle door system.

In the embodiment of the present invention, in order to reduce the connection difficulty and connection restriction between the area controller and the door leaf controller, the area controller and the door leaf controller are connected by a network communication method. Specifically, the two can be connected through a network communication. RS485 communication, CAN communication, Ethernet, Ethercat communication, MVB communication and 4G/5G communication and other network communication methods are coupled, and there is no restriction here.

In addition, it should be noted that the number of area controllers and door leaf controllers in the embodiment of the present invention can be set according to the needs of actual application scenarios. Specifically, the number of door leaf controllers and the actual application scenarios of the door system The number of rail vehicle door leaves that need to be controlled, that is, the number of door leaf drive mechanisms that need to be controlled is the same, and the number of area controllers can be set according to the number of door leaf controllers. Specifically, due to subway or high-speed rail, etc. Generally, there are many door leaves in the door system of rail vehicles. Therefore, each car or every several cars can be equipped with an area controller to control the door controller in the corresponding car or several cars.

Example 1

Fig. 2 shows a flowchart of a door leaf control method of a rail vehicle door system provided by an embodiment of the present invention. As shown in Fig. 2, the method may include the following steps:

S201: Control the operation of the door leaf of the rail vehicle according to the door leaf control instruction sent by the area controller, and obtain the first operating state data of the door leaf of the rail vehicle during operation.

In the embodiment of the present invention, the door leaf control instruction is generated by the area controller according to the received general control instruction. Specifically, as shown in FIG. 1, one end of the area controller is connected to the door leaf controller in network communication, and the other end is connected to the general control instruction. The controller (such as the vehicle driver control side in the subway car door system) is connected (although in Figure 1 the regional cloud is connected to the master controller as a whole, it should be understood by those skilled in the art that each of the regional clouds is The area controllers are all connected to the main controller), specifically, the area controllers can still be connected to the main controller through hard-wired methods. Of course, since one area controller is generally connected to multiple door leaf controllers in network communication (One zone controller controls the operation of multiple zone controllers). The number of zone controllers is much smaller than the number of door leaf controllers. Therefore, even if the zone controllers are hard-wired with the overall controller, the entire door system The volume is still small.

In the embodiment of the present invention, since one area controller can be connected to multiple door leaf controllers in network communication, in order to enable door leaf control commands to be sent to each corresponding door leaf controller, it is necessary to determine the relationship between the area controller and the door leaf controller. The specific network communication mode of the controller and the MAC address of the door leaf controller that needs to send the door leaf control instructions encode the total control instruction, thereby generating the door leaf control instructions of each door leaf controller.

In the embodiment of the present invention, the first operating state data may include one or more of the door leaf state data and the door leaf driving mechanism operation data. Specifically, the door leaf state data may be based on the state data on the door leaf during the operation of the door leaf. The state data of a variety of mechanical switches (such as close position switch, lock position switch, isolating switch and emergency unlock switch, etc.) can be obtained, and it can also be detected by sensors near the door leaf to detect the operating state of the door leaf (such as image sensors and position sensors, etc.) ) Data is obtained. Therefore, the door leaf state data can include mechanical switch state data and sensor data; the door leaf drive mechanism (in this embodiment of the invention, the door leaf drive mechanism is taken as an example of the drive motor for illustration) operating data can be passed through the door leaf drive mechanism during operation The operating time, operating current, temperature, etc. of the door leaf drive mechanism may include one or more of operating time data, operating current data, and temperature data of the drive mechanism.

S202: Judging whether the rail vehicle door leaf is abnormal according to the first operating state data, obtaining a first judgment result, and sending the first judgment result to the area controller.

Following the above example, the first operating state data includes the mechanical switch state data of the door leaf, and the mechanical switch includes the closed end switch as an example to illustrate the embodiment of the present invention. Then, when the door leaf of the railway vehicle is controlled to close, the end switch is closed within the first predetermined time. When the state is not switched, the first judgment result is that the rail vehicle door leaf is abnormal. Specifically, if the rail vehicle door leaf is normal, when the door leaf is not closed, the above closed position switch is in the first state. When the door leaf is closed, The above-mentioned open end switch is in the second state, and if the first predetermined time has passed after the door leaf controller starts to control the closing of the vehicle door leaf, and the closed end switch has not switched from the first state to the second state, the first judgment result is the track The door leaf of the vehicle is abnormal.

Taking the first operating state data including the mechanical switch state data of the door leaf, and the mechanical switch including the lock-in switch as an example, the embodiment of the present invention will be described. Then, the state of the lock-in switch is not switched within the second predetermined time after the door leaf of the control rail vehicle is closed. When the first judgment result is that the rail vehicle door leaf is abnormal, the specific judgment situation can be understood by referring to the above-mentioned specific judgment method for judging whether the rail vehicle door leaf is abnormal based on the closed position switch, and will not be repeated here; take the first operating state data Including the state data of the mechanical switch of the door leaf, and the mechanical switch includes an isolating switch as an example to illustrate the embodiment of the present invention, when the isolating switch is from the normal state (the normal state is the untriggered state, the signal of the isolating switch can be high Level signal, can also be low level information) to switch to the unconventional state (the unconventional state is the trigger state, when the signal when the isolating switch is in the regular state is a high level signal, the information of the unconventional state is low Level signal, when the signal when the isolating switch is in the normal state is a low-level signal, the information of its unconventional state is a high-level signal), the first judgment result is that the rail vehicle door leaf is abnormal; in the first operating state The data includes the state data of the mechanical switch of the door leaf, and the mechanical switch includes the emergency unlocking switch as an example to illustrate the embodiment of the present invention, when the emergency unlocking switch is switched from the normal state to the unconventional state (refer to the specific content of the above isolation switch for understanding ), the first judgment result is that the rail vehicle door leaf is abnormal.

According to the first operating status data, the operating status data includes the operating status data of the door leaf, when the operating status data of the door leaf drive mechanism does not meet the requirements of the door leaf control instruction, for example, if the door leaf control instruction is a door opening instruction, and the drive direction of the door leaf drive mechanism To drive the closing direction of the door leaf, the operating state data of the door leaf drive mechanism does not meet the requirements of the door leaf control instruction, and the first judgment result is that the rail vehicle door is abnormal; or the operating state data of the door leaf drive mechanism contradicts the mechanical switch state data, for example, if The end-close switch in the mechanical switch is triggered, that is, when the state of the rail vehicle door leaf fed back by the end-close switch is in the closed position, and the operating speed (or operating current) of the door leaf drive mechanism is still large, the operating state data of the door leaf drive mechanism Contrary to the mechanical switch state data, the first judgment result is that the rail vehicle door is abnormal.

S203: When the first judgment result is that the rail vehicle door leaf is abnormal, control the rail door leaf to maintain a closed state.

In the embodiment of the present invention, when the door leaf of the rail vehicle is judged to be abnormal, the door leaf controller will send the judgment result to the area controller. When the area controller receives the judgment result, it will no longer send the judgment result to the rail vehicle. The door leaf sends a door leaf control instruction (door opening instruction), so that the door leaf controller can control the track door leaf to remain closed until the track vehicle door leaf returns to the normal state.

In the embodiment of the present invention, when the rail vehicle door leaf is judged to be abnormal and the door leaf control instruction (door opening instruction) sent by the area controller is received, the track door leaf may be controlled to remain closed, and then the judgment result may be sent to the area When the controller and the zone controller receive the judgment result, it will no longer send door leaf control instructions (door opening instructions) to the rail vehicle door leaf, so that the door leaf controller can control the track door leaf to remain closed.

In the embodiment of the present invention, the door leaf controller that realizes the door leaf control method of the rail vehicle door system is connected to the area controller network to realize the door leaf controller and its control mechanism (in the present invention, the area controller, the prior art The middle is the vehicle driver's side, that is, the transmission side of the master control instruction, that is, the transmission of control instructions and feedback information of the master controller, which can reduce the complexity of the electrical connection structure of the system that implements the door leaf control method of the rail vehicle door system Therefore, the electrical connection stability and reliability of the system that implements the door leaf control method of the rail vehicle door system can be improved; in addition, the operation of the rail vehicle door leaf is controlled according to the door leaf control instruction sent by the regional controller, and the door leaf control instruction It is generated by the regional controller according to the received general control instruction, and sends the first judgment result of whether the rail vehicle door leaf is abnormal according to the acquired operating state data of the rail vehicle door leaf during operation to the regional controller, The door leaf controller does not need to be directly electrically connected to the main controller. Therefore, regardless of whether the fixed and unchangeable electrical connection mode of the main controller and other devices of the rail vehicle in the door leaf control method of the rail vehicle door system includes hardware Connected, the door leaf controller of the implementation system of the door leaf control method of the rail vehicle door system (because the door leaf controller corresponds to each door leaf of the rail vehicle one-to-one, therefore, the number of door leaf controllers is large) does not need to be directly connected with the master control The device is electrically connected in a hard-wired manner, so that the complexity of the hard-wired connection mechanism existing in the execution system of the door leaf control method of the rail vehicle door system can be reduced, so as to further implement the door leaf control of the rail vehicle door system The stability and reliability of the electrical connection of the system of the method.

As an optional implementation of this embodiment, in order to realize the self-check of the door leaf controller, as shown in FIG. 3, the door leaf control method of the rail vehicle door system in the embodiment of the present invention further includes the following steps:

S204: Acquire the second operating state data of the internal device of the door leaf controller.

In the embodiment of the present invention, the second operating state data may include at least one of operating voltage data, operating current data, and operating temperature data. Specifically, taking the second operating state data including operating voltage data, operating current data, and operating temperature data as an example, a voltage sensor, a current sensor for detecting the door leaf controller, and a current sensor for detecting the internal components of the door leaf controller can be set. Temperature sensor, and send the voltage detection signal, current detection signal and temperature detection signal to the control unit in the door leaf controller through the ADC conversion module, so as to obtain the second operating state data of the internal device of the door leaf controller.

S205: Determine whether the door leaf controller is abnormal according to the second operating state data, obtain a second judgment result, and send the second judgment result to the area controller.

In the embodiment of the present invention, following the above example, when the difference between the operating voltage of the door leaf controller and the standard voltage is greater than the preset voltage threshold, the second judgment result that the door leaf controller is abnormal is obtained; when the door leaf controller operates When the current is greater than the preset current threshold, the second judgment result of the door leaf controller being abnormal is obtained; when the operating temperature of the door leaf controller is higher than the preset temperature, the second judgment result of the door leaf controller being abnormal is obtained.

As an optional implementation of this embodiment, as shown in FIG. 3, after the above steps S201-S205, the door leaf control method of the rail vehicle door system further includes the following steps:

S206: Receive and store door controller update data and update verification data sent by the area controller.

In the embodiment of the present invention, the update data is software update data or control parameter update data. Specifically, the software update data is used to update the door leaf controller to implement the door leaf control of the rail vehicle door system in the embodiment of the present invention. The program instructions of the method, the parameter update data is used to update the control parameter data used to control the operation of the door leaf drive mechanism in the door leaf controller (for example, the maximum operating current of the door leaf drive mechanism, the door opening time of the door leaf of rail vehicles, and the door leaf drive mechanism drive track The current change curve of the vehicle door leaf opening and the current change curve of the door leaf drive mechanism driving the rail vehicle door leaf to open the door, etc.).

Here, it should be noted that the difference between the control parameter update data in this step and the mode selection data in the following steps S401 and S402 is that the operation mode corresponding to the mode selection data in step S401-step S402 is In the operating mode, all control parameter data will be limited, that is, the mode selection data is used to update all control parameter data, and the control parameter update data in step S206 is only used to update all control parameters One or more of the data, in actual use, when the rail vehicle changes, for example, from a sliding door type rail vehicle to an external closed door type rail vehicle, it is generally necessary to change all the control parameter data, It is updated by the mode selection data in step S401-step S402; and when the rail vehicle has not substantially changed, but only the environmental parameters or details of the rail vehicle, for example, the operating environment temperature of the rail vehicle When a major change occurs, the smoothness of the running path changes greatly, or the running time of the rail vehicle is longer, the internal mechanical structure is more severely worn, etc., generally only certain specific operating parameters need to be changed. The control parameter data is updated through the control parameter update data in step S206.

In the embodiment of the present invention, the received door leaf controller update data and update check data can be stored in a random access storage area (RAM) in the door leaf controller.

S207: Verify the integrity of the update data of the door leaf controller according to the update verification data.

In the embodiment of the present invention, verifying the integrity of the update data of the door leaf controller according to the update verification data can be achieved by using any existing data integrity verification algorithm, which will not be repeated here.

S208: When the verification result is that the door leaf controller update data is complete, use the door leaf controller update data to update the door leaf controller.

In the embodiment of the present invention, when the verification result is that the update data of the door leaf controller is complete, the update data of the door leaf controller can be rewritten or copied to the read-only memory area (ROM) of the door leaf controller, and the door leaf control is used. The controller update data updates the door leaf controller.

In the embodiment of the present invention, when the door leaf controller update data and update verification data sent to the area controller, and when the door leaf controller update data is verified as completed data, the door leaf controller update data pair is used The update of the door leaf controller can realize the automatic update of the door leaf controller and improve the update efficiency of the door leaf controller.

As an optional implementation of this embodiment, as shown in FIG. 3, after step S208, the door leaf control method of the rail vehicle door system further includes the following steps:

Step S209: Obtain the external environment data of the door leaf of the rail vehicle.

In the embodiment of the present invention, the external environment data includes pressure data applied to the door leaf of the rail vehicle. Specifically, the pressure data can be obtained by setting a pressure sensor on the door leaf of the rail vehicle.

Step S210: Adjust the control parameter data according to the external environment.

In the embodiment of the present invention, when the pressure applied to the door leaf of the rail vehicle increases by a first predetermined value, the operating current when the door leaf drive mechanism drives the door leaf of the rail vehicle to open and close the door is increased by the second predetermined value accordingly. Of course, The increased operating current cannot be higher than the predetermined maximum operating current. In practical applications, if the pressure applied to the rail vehicle door leaf is greater than the pressure corresponding to the predetermined maximum operating current, a warning message will be issued to remind the management personnel to conduct manual review .

It should be noted that those skilled in the art should understand that the above-mentioned step S209-step S210 can also be performed after any one of step S201-step S207, or at the same time as any one of the above-mentioned step S202-step S208. I won't repeat them here.
