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.

Example 1

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.

FIG. 2 shows a flowchart of a method for controlling a door system of a rail vehicle according to an embodiment of the present invention. As shown in FIG. 2, the method may include the following steps:

S201: The area controller generates door leaf control instructions of each door leaf controller according to the received general control instruction, and sends the door leaf control instructions to the corresponding door leaf controller. In the embodiment of the present invention, the door leaf controller controls the operation of the corresponding door leaf drive mechanism according to the door leaf control instruction.

In the embodiment of the present invention, as shown in Figure 1, one end of the regional controller is coupled with the general controller (such as the vehicle driver control side in the subway door system). Specifically, the regional controller can still be hard-wired Mode or network communication is coupled with the master controller. Of course, since the number of zone controllers is much smaller than the number of door leaf controllers, even if the zone controllers are coupled with the master controller through hard-wired methods, the entire door The volume of the system is still small.

In the embodiment of the present invention, the area controller is coupled with each door leaf controller through network communication. Specifically, the two can be communicated through RS485, CAN, Ethernet, Ethercat, MVB, 4G/5G, etc. Any network communication method is coupled. Therefore, the area controller needs to be based on the specific network communication method between the area controller and the door leaf controller according to the received total control instruction, and the MAC address of the door leaf controller that needs to send the door leaf control instruction Encode the total control instruction to generate the door leaf control instructions of each door leaf controller.

S202: The area controller adjusts the operating parameters of the door leaf controller according to the received environmental parameters of the rail vehicle. In the embodiment of the present invention, the initial operating parameters of the door leaf controller are preset parameters.

In the embodiment of the present invention, the received environmental parameters of the rail vehicle include external or internal environmental parameters of the rail vehicle. Specifically, the environmental parameters may include one or more of temperature condition parameters, air pressure condition parameters, and passenger load data. Among them, the temperature condition parameters can be obtained by the temperature detection device installed in the rail vehicle, and the air pressure condition parameters (generally including the air pressure data inside the door leaf and the air pressure data outside the door leaf) can be detected by the air pressure detection device installed on the rail vehicle Device (correspondingly, the air pressure detection device generally includes two air pressure detection devices installed in the rail vehicle and an air pressure detection device installed outside the rail vehicle). The passenger load data can be collected by the air pressure detection device installed on the rail vehicle. One or more camera devices for the video or image of passengers in the rail vehicle, and/or through one or more camera devices installed on the rail vehicle for collecting the video or image of passengers in the rail vehicle (This data is generally not directly available, and it is necessary to perform face or human body detection on the acquired video), specifically, whether only the camera device is installed in the rail vehicle, or only the camera device outside the rail vehicle, or in the rail vehicle and the rail Cameras installed outside the vehicle can be set according to the needs of specific application scenarios, and there are no restrictions here.

In the embodiment of the present invention, if the environmental parameters include temperature condition parameters, air pressure condition parameters, and passenger load data, the door leaf can be controlled by calculating the weights and values of the corresponding operating parameters under each environmental parameter. The operating parameters of the device are adjusted.

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 area controller generates the door leaf control instructions of each door leaf controller according to the received total control instructions , And send the door leaf control instructions to the corresponding door leaf controller, so that the door leaf controller does not need to be directly electrically connected with the main controller. Therefore, regardless of the rail vehicle door leaf control method of the rail vehicle door system, the rail vehicle has been set and cannot be changed Whether the electrical connection between the master controller and other devices includes hard-wiring, the door leaf controller of the execution 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, There is no need to directly connect with the main controller in a hard-wired manner, so that 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. Complexity, thereby further improving the electrical connection stability and reliability of the system implementing the door leaf control method of the rail vehicle door system.

In the embodiment of the present invention, the state parameters of the door leaf drive mechanism may include the door opening time and the door closing time. Specifically, the area controller may determine the corresponding door opening time when the difference between the received door opening time and the historical average door opening time reaches the first threshold. The evaluation result of the door leaf drive mechanism is that the door leaf drive mechanism does not meet the requirements of normal operating conditions; the zone controller can also determine the corresponding door leaf drive mechanism when the difference between the received closing time and the historical average closing time reaches the second threshold The evaluation result of is that the door leaf drive mechanism does not meet the requirements of normal operating conditions. Specifically, the first threshold and the second threshold may be the same threshold or different thresholds, and the magnitude of the first threshold and the second threshold may be based on In the specific application scenario, the historical data of the door opening time and closing time in the track door system, and the time accuracy requirements for opening and closing the door are set, and there is no restriction here.

In the embodiment of the present invention, if the area controller is coupled with multiple door leaf controllers, the area controller can receive the opening and closing time and the door closing time sent by the multiple door leaf controllers; specifically, the area controller can respond to multiple door leaf controllers. The door opening time sent by the zone control is compared, and it is determined that the door leaf drive mechanism corresponding to the maximum value of the door opening time sent by the multiple door leaf controllers does not meet the requirements of normal operating conditions, so that a warning message is sent to remind the management personnel to respond to the corresponding The door leaf drive mechanism is inspected; the area controller can also compare the door closing time sent by multiple area controls, and determine that the door leaf drive mechanism corresponding to the maximum value of the door closing time sent by the multiple door leaf controllers has not reached the normal operating condition In response to the requirements, a warning message is sent to prompt the management personnel to inspect the corresponding door drive mechanism.

In the embodiment of the present invention, when the temperature condition parameter is lower than the preset temperature, the operating parameter is adjusted to increase the driving force of the door leaf drive mechanism driven by the door leaf controller. Specifically, when the temperature condition parameter is lower than the preset temperature When the temperature is 10°C, the operating parameters are adjusted once. Of course, the operating parameters can also be adjusted once when the temperature condition parameters are lower than the preset temperature by 8°C or 12°C. The specific adjustment interval can be carried out according to the actual application scenario. Settings, there are no restrictions here.

If the current passenger load is less, the minimum passenger load is reached or exceeded. Part of the door leaf controller is excluded from the predetermined door leaf controller, that is, only a part of the left door leaf in the direction of subway operation is opened. For example, if the left side of a car includes 10 door leaves, only 7 of them are opened, of course The above specific numerical values are only examples for the convenience of those skilled in the art to understand the specific solutions of the embodiments of the present invention, and should not constitute any limitation to the present invention.
