Description

Technical Field

[0001] The present invention relates to the field of data communication technology for coal mining machine equipment, and specifically to a method for displaying a human-computer interaction interface of a coal mining machine based on the Hongmeng system. Background Art

[0002] Traditional coal mining machine control systems have some limitations, such as lack of interconnection between devices, inconsistent data formats and standards, incompatible communication protocols, etc. These problems have led to the existence of information barriers and information islands, hindering the progress of intelligent coal mines. In order to solve these problems, the Hongmeng operating system is introduced into the coal mining machine control system, so that the coal mining machine control system can work more effectively and improve overall efficiency.

[0003] ArkTs is the Hongmeng ecosystem application development language provided by Huawei for R&D personnel. It provides corresponding capabilities such as declarative UI paradigm and state management support. Developers can develop applications in a simpler and more natural way when interacting with the host computer based on the Hongmeng system. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems in the related art to a certain extent. To this end, the present invention provides a method for displaying a human-machine interactive interface of a coal mining machine based on the Hongmeng system, which integrates the data of various parts of the coal mining machine during operation and uses an integrated human-machine interface to display the data of all devices, which is conducive to real-time monitoring of the health status of the equipment and related data, and is also useful for centralized control in the future.

[0005] To achieve the above-mentioned purpose, in the first aspect, the present application provides a method for displaying a human-machine interactive interface of a coal mining machine based on the Hongmeng system, wherein the human-machine interface is simultaneously connected to information collection sensors of multiple coal mining machines through a communication bus to obtain corresponding data information, and the display method includes:

[0006] According to the data parameters collected by the sensor, update the data that needs to be traversed in the traversal container;

[0007] Use the set data communication parameters to try to establish a data communication connection with the coal mining machine equipment;

[0008] Preferably, searching for the information collection sensor through Ethernet broadcast and traversal algorithm includes: searching and determining the data of the sensor device through the broadcast function of the TCP Ethernet protocol, and determining the port number of the sensor device.

[0009] Preferably, the current data of the sensor device is determined by searching through a broadcast function of the TCP Ethernet protocol.

[0010] Preferably, the current IP addresses of other devices in the Hongmeng ecosystem, such as scraper conveyors, tunneling machines, etc., are searched and determined through the broadcast function of the TCP Ethernet protocol.

[0011] Receive information through the human-machine interface, and the receiving port is the receiving port encapsulated under the project;

[0012] Monitor and receive data from the receiving port multiple times;

[0013] The human-machine interface receives data information at the receiving port, parses the data information through JSON.Parse and verifies whether it is the data information sent by the sensor device.

[0014] When the coal mining machine is started, the data information sent by the sensor equipment is received by the PLC controller, and the PLC transmits data to the Hongmeng module.

[0015] Preferably, when establishing a connection, the port number of the sensor device is determined, for example:

[0016] First, find the first-layer MDTP basic model, with the default value of the MDTP index number 0xB001 as the root node, where the 0xB001 root node has a child node instance ID of 0x0001, which is the second-layer MDTP instance model;

[0017] Select the child node of node 0x0001, and continue to query the child nodes of node 0x0001. The child nodes of node 0x0001 include the third-layer nodes 0x001-0x065, and the third layer is the MDTP method model / attribute model;

[0018] Select the child node 0x001 of node 0x0001, and continue to search for the child nodes of node 0x001. The child nodes of node 0x001 include nodes bit1-bit16, and the fourth layer is a bit-by-bit detailed description.

[0019] Select the child node bit1 of 0x001, and form a set of MDTP data parameters with 0xB001, 0x0001, 0x001, and bit1;

[0020] Use 0xB001, 0x0001, 0x001, bit1 to build a communication connection. If the data request sent by the human-machine interface gets a data response from the device, the communication connection is successfully built and the traversal ends. If the data request sent by the human-machine interface does not get a data response from the device, use 0xB001, 0x0001, 0x001, bit2 and 0xB001, 0x0001, 0x001, bit3 to build a communication connection in sequence. If the communication connection is not successfully built, return to the third layer;

[0021] Use 0xB001, 0x0001, 0x002, bit1, 0xB001, 0x0001, 0x002, bit2 in sequence to build a communication connection. If the communication connection is not successfully built, return to the second layer;

[0022] Use 0xB001, 0x0001, 0x001-0x065, bit1-bit16 in sequence to build a communication connection. If the communication connection is unsuccessful, return to the first layer;

[0023] Use 0xB001-0xB005, 0x0001, 0x001-0x065, bit1-bit16 in sequence to build a communication connection.

[0024] The display control method also includes that when the human-machine interface is successfully matched with the sensor device, the human-machine interface reads and displays data information of the sensor device from the matched sensor device.

[0025] The human-machine interface obtains data from the sensor device through the Hongmeng module in the manner specified by the MDTP communication protocol, and the sensor device continuously sends the latest data information to the human-machine interface through the MDTP communication protocol.

[0026] The human-machine interface receives data information and displays the data;

[0027] The human-machine interface can refresh the displayed data by switching pages as needed.

[0028] In the second aspect, the present invention provides a coal mining machine human-machine interaction interface display control method based on the Hongmeng operating system, the display control system includes a number of sensor parts along the coal mining machine motor current, traction direction, cutting speed, etc., each sensor part is provided with a corresponding sensor device, and also includes a human-machine interface, and several of the sensor devices are communicatively connected to the human-machine interface through a communication bus, the sensor device includes an information collection component for detecting the operating status of the sensor part, and the information collection component includes a temperature sensor, a flow sensor, a pressure sensor, a speed sensor, etc.

[0029] The communication protocol of the communication bus adopts the MDTP protocol.

If the search result fails, a failure is returned, and a prompt is given that no sensor device is matched. If the search for the sensor device is successful, a prompt is given for the matched sensor device, and the IP address information of the sensor device is displayed.

[0045] like Figure 3As shown, the display control method also includes when the human-machine interface and the sensor device are successfully matched, the human-machine interface reads and displays the data information of the sensor device from the matched sensor device; the human-machine interface sends a data request to the sensor device in the manner specified by the communication protocol, and the sensor device sends the data information to the human-machine interface in the manner specified by the communication protocol after receiving the data request.

[0046] The human-machine interface receives data information and filters out the data to be displayed:

[0047] The human-machine interface rearranges and displays the filtered data to be displayed;
