DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work, any modifications, equivalent substitutions, improvements, etc., should be included in the protection scope of the present invention.

[0015] like Figure 1 , Figure 2 As shown, this embodiment discloses a filling support rear control emergency stop locking system, the system includes a business management module for overall business processing, a port management plug-in for implementing port connection tasks, an inter-rack link data processing module for implementing communication connection, a port data processing plug-in for analyzing the transmission signal of the port connection device, an emergency stop locking business processing plug-in for providing an emergency stop action instruction, an action executor plug-in for providing an execution action instruction, a parameter management module for managing various information parameters, a UI human-computer interaction module for performing human-computer interaction operations, and a storage module for storing various information parameters; The business management module is respectively connected to the port management plug-in, the inter-frame link data processing module, and the port data processing plug-in to realize signal transmission. The port management plug-in and the port data processing plug-in are both connected to several external emergency stop locking devices arranged in the rear working area of ​​the filling support to realize signal transmission; the port management plug-in and the port data processing plug-in are connected to each other to realize signal transmission; the inter-frame link data processing module is connected to several working face support equipment controllers arranged in the front working area of ​​the filling support to realize signal transmission; the several external emergency stop locking devices and several working face support equipment controllers are all arranged corresponding to the comprehensive mining working face support.

[0016] The emergency stop and lock service processing plug-in and the action actuator plug-in are both connected to the service management module to realize signal transmission.

[0017] The parameter management module is respectively connected to the business management module, the port management plug-in, the storage module, and the UI human-computer interaction module to realize signal transmission; the UI human-computer interaction module is connected to the business management module to realize signal transmission.

[0018] For port configuration management: the port management plug-in of the system supports differentiated configuration. The same port can be connected to different external devices. One of the ports can be configured as an external emergency stop locking device interface. The configuration is done using a json format file. The configuration is simple and convenient, and it can be used immediately after being uploaded.

[0019] For the operation management system: the rear external emergency stop locking technology can realize the locking of the bracket, the adjacent bracket or the emergency stop of the entire working surface, which depends on the controller installed on each bracket; the business management module uses the PhyCORE-i.MX 6ULL ​​module main processor, the STM32F427 chip is the auxiliary MCU, and is equipped with an HMI module, a main control module, and an interface module to realize sensor data collection, human-computer interaction, data processing and other functions. The internal power supply circuit uses a dual-power supply, and the main control and port power supplies are separated to ensure that the main control unit is not affected by abnormal conditions of external devices; Inter-rack link data processing module: It adopts a combination of Gigabit vehicle Ethernet and inter-rack CAN bus, using Gigabit vehicle Ethernet communication link to increase link transmission bandwidth and inter-rack CAN signal isolation coupling to improve the stability and real-time performance of data transmission between equipment and within the work surface electronic control system; In implementing the rear external emergency stop locking technology solution, each support is equipped with a rear emergency stop locking device. In an emergency, workers can directly operate it to control the locking of the support, adjacent support, or the emergency stop of the entire working surface, quickly stop the support movement, and ensure personnel safety.

[0020] At the same time, this embodiment also discloses a working method of a filling support rear control emergency stop locking system, which includes the following steps: S1. When the external emergency stop locking device is operated, it transmits the operation signal to the port data processing plug-in; S2, the port data processing plug-in analyzes the specific operation signal of the operation signal and transmits the specific operation signal to the business management module; Specific operation signals include the stop signal of a single corresponding comprehensive mining working face support, the action signal of a single corresponding comprehensive mining working face support, the stop signal of an adjacent comprehensive mining working face support, the action signal of an adjacent comprehensive mining working face support, the stop signal of all comprehensive mining working face supports, and the action signal of all comprehensive mining working face supports.

[0021] S3, the business management module maintains a signal connection state with the working face support equipment controller through the inter-frame link data processing module; S4. After receiving the specific operation signal, the business management module transmits the control instruction to the working face support equipment controller through the inter-frame link data processing module, so that the working face support equipment controller controls the working state of the comprehensive mining working face support.

[0022] The rear external emergency stop locking device is an external device, such as Figure 2As shown, the emergency stop and lock system of the rear control of the filling support will first initialize and manage the port connected to the device so that the port can communicate normally with the device. The device then reports the device status signal (including emergency stop status, lock status, and idle status) to the port data processing plug-in of the emergency stop and lock system of the rear control of the filling support at a certain frequency. After parsing the signal data, the plug-in forwards the status signal to the emergency stop and lock business processing plug-in. The emergency stop and lock business processing plug-in and the business management module transmit the emergency stop signal to the working face support equipment controller through the inter-frame link data processing module, thereby realizing regional locking and comprehensive emergency stop of the working face, stopping the support action, and ensuring personnel safety. Therefore, the operating stability of the external device and the normal communication link of the device are crucial. Based on these two considerations, we have added a communication link heartbeat detection function to monitor the communication status with the external device in real time.

[0023] like Figure 3 As shown, the communication link heartbeat detection function is summarized as follows: the filling bracket rear control emergency stop locking system turns on the power supply of the external device through the port management plug-in, initializes the management of the communication port, establishes communication between the controller and the external device, and the device will immediately report the device online signal. After receiving the signal, the controller will immediately take the initiative to establish a heartbeat detection connection with the device. After the establishment is successful, a heartbeat detection signal is sent every 1.5 seconds. The device immediately replies after receiving the signal, indicating that the communication between the controller and the device is normal. When the controller sends a heartbeat detection signal, if the signal reply is not received after a timeout of 3 seconds, the controller defaults to a communication timeout and immediately resends the connection establishment signal until a new heartbeat connection is established with the device. At this time, the state of the controller will remain in the current state to ensure safety. When the external device does not receive the heartbeat detection signal of the controller after a timeout of 3 seconds, it will also default to a communication timeout, stop reporting the status signal, and continue to send the device online signal until the connection with the controller is reestablished. The device will continue to detect its own state. After the communication is restored, the state of the external device can be immediately reported to the controller.

[0024] The parameters of the business management module are divided into local parameters and global parameters, and are password protected. Use the UI human-computer interaction interface to set the parameters, which are then received by the parameter management module and saved to the storage module.

[0025] The port management plug-in will retrieve the port configuration file, obtain all the configuration parameters of the device, and perform initialization management to achieve differentiated port configuration, which is easy to operate. The device type parameter is a local parameter, which ensures that the working surface can be configured differently. At the same time, the update method of the parameter (local update and global update) can be specified, which enables the local parameter to be updated globally. The advantage is that in the filling bracket working surface, the device type can be set to an external emergency stop locking device on any controller.

[0026] In order to ensure that the parameters are not changed at will, three levels of passwords are set when setting parameters in the UI human-computer interaction (6-digit random digital passwords can be customized), namely user-level passwords (used by on-site personnel), technician passwords (used by comprehensive mining technicians), and administrator passwords (used by manufacturers). Different levels of passwords are configured according to parameter types and importance. In addition, the parameter settings can be controlled. Only parameter values ​​within the allowable range can be saved successfully, otherwise the original parameter values ​​remain unchanged.

[0027] The present invention has the following beneficial effects: 1. Port differentiated configuration: Devices of different types can be configured into the port configuration file, and then the device type parameters can be modified through the human-machine interface. The port management plug-in retrieves the port configuration file based on the parameters to obtain all configuration parameters of the external device for initialization management, and can specify the parameter update method, supporting local update and global update methods to achieve differentiated configuration of the work surface.

[0028] 2. Diversified parameter types and password protection: Only when the external device type is selected correctly can it operate normally, so the reliability of parameter configuration is crucial. In order to prevent the parameters from being changed at will, different protection passwords are set according to the parameter type and importance. Parameters are divided into local and global, and the update method can specify local and global updates, which can be applied to different functional requirements.

[0029] 3. The present invention is developed and designed based on the original electro-hydraulic control system, and provides operators at the rear of the filling support with a solution that is easy to operate and can lock or stop the support action in a timely and effective manner, thereby reducing the safety risks of personnel operations; the operation is simple and quick for personnel, which reduces the input of personnel underground in the coal mine to a certain extent, improves the intelligence level and mining efficiency of the comprehensive mining working face, and reduces the safety risks of personnel.
