Description

Technical Field

[0001] This invention relates to the field of data monitoring technology, specifically to a data monitoring device and method for mining lithium battery locomotives. Background Technology

[0002] As a core piece of equipment for underground auxiliary transportation, mining lithium battery locomotives typically require frequent starts, stops, accelerations, and braking during operation in underground mine roadways. Their complex and variable operating conditions mean that the battery packs of lithium battery locomotives generally operate under conditions of intermittent start-stop vibration with high current. Therefore, battery safety is directly related to coal mine production efficiency and the safety of underground personnel.

[0003] In the traditional monitoring mode, when the mining lithium battery locomotive moves along the roadway underground, the communication link between the ground and underground fluctuates continuously as the locomotive's position changes. It is easily affected by the complex electromagnetic environment and roadway structure, which makes it easy for the monitoring and transmission data of the battery pack to be lost or delayed. Therefore, it is easy to fail to provide timely warnings for core parameters such as the voltage, temperature and remaining power of the lithium battery pack.

[0004] In addition, traditional monitoring systems are mostly one-way data upload architectures, lacking the ability of ground-based host computers to reverse control the downhole data, making it difficult to dynamically adjust the frequency and parameter types of the collected data according to the actual working conditions, resulting in excessive redundant data and large errors in the uploaded monitoring data. Summary of the Invention

[0005] I. Technical problems to be solved Therefore, the present invention provides a data monitoring device and method for mining lithium battery locomotives, which can reduce redundant data and enhance the communication adaptability of the monitoring device to the mining environment.

[0006] II. Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a data monitoring device for a mining lithium battery locomotive, the device comprising the following modules: The gateway acquisition module is used to collect multi-source locomotive data from mining lithium battery locomotives. The gateway acquisition module includes an RS485 interface, a CAN interface, and a switch interface, and is configured with an acquisition and parsing protocol algorithm. According to the communication protocol of the access device, the acquired multi-source locomotive data is parsed, verified, and preprocessed, and then a standard multi-source locomotive signal is output. The data transmission module is used to receive the standard multi-source locomotive signals, integrate and encapsulate the locomotive signals from different acquisition sources according to the preset data encapsulation rules, and send the encapsulated multi-source locomotive signals to the monitoring and display module through a wired communication link based on the communication protocol. The monitoring and display module includes a tablet terminal and a monitoring application running on it. Each monitoring application in the monitoring and display module receives the encapsulated multi-source locomotive signals through the communication port, and performs application-layer decoding on the multi-source locomotive signals according to the data frame header and data type. The decoded locomotive signals are then visualized, displayed, and stored. The decoded locomotive signals include the total battery voltage, total current, remaining power, individual cell voltage and individual cell temperature, as well as abnormal warning information. The host computer module generates corresponding acquisition control commands based on the decoded locomotive signals and the operating conditions of the mine locomotive. The host computer module then sends each acquisition control command back to the gateway acquisition module through the data transmission module to control the acquisition parameters of the gateway acquisition module. The acquisition parameters include data acquisition frequency, acquisition channel start / stop, and acquisition data type.

[0007] Furthermore, the mining lithium battery locomotive includes an underground lithium battery electric locomotive and a lithium battery monorail crane. The multi-source locomotive data initially collected by the gateway acquisition module includes the voltage parameters of the underground lithium battery electric locomotive, as well as the battery pack voltage parameters, locomotive power parameters, and acquisition environment parameters of the lithium battery monorail crane.

[0008] Furthermore, the gateway acquisition module is configured with an acquisition and parsing protocol algorithm to parse the multi-source locomotive data. The acquisition and parsing protocol algorithm uses a multi-protocol parsing library to match the communication baud rates and data frame formats of RS485, CAN, and switch signals of the multi-source locomotives, thereby parsing the multi-source locomotive data.

[0009] Furthermore, the gateway acquisition module preprocesses the multi-source locomotive data and outputs a standard multi-source locomotive signal; the gateway acquisition module sets a preset filtering threshold for the multi-source locomotive signal to filter out misaligned, abrupt, and invalid data in the multi-source locomotive signal, and filters out multi-source locomotive data that is not greater than the preset filtering threshold, and outputs a standard multi-source locomotive signal.

[0010] Furthermore, the data transmission module receives the standard multi-source locomotive signals. The data transmission module is equipped with RS485 and CAN communication protocols. The data transmission module divides the multi-source locomotive signals according to the attributes of locomotive parameters through the communication protocols, splices locomotive data with the same attributes, and merges and encapsulates locomotive signals from different acquisition sources.

[0011] Furthermore, the monitoring and display module acquires the locomotive signal merged and encapsulated by the data transmission module, receives the locomotive signal through the listening port in the tablet computer, and the listening port parses the frame header of the multi-source locomotive signal according to the data type of the multi-source locomotive signal, and displays the parsed locomotive signal on the display screen of the tablet computer.

[0012] Furthermore, the host computer module receives the parsed locomotive signal and transmits it in reverse to the data transmission module to control the logic of the gateway acquisition module to collect multi-source locomotive signals. The processed multi-source locomotive signals are then uploaded to the monitoring and display module via wireless signal. The host computer module controls the monitoring and display module to display the processed multi-source locomotive signals, thereby monitoring the data of the mining lithium battery locomotive in real time.

[0013] Furthermore, the monitoring device also includes a power supply module, which includes a power conversion and isolation unit for drawing power from the mining lithium battery locomotive power supply and providing a stable operating power supply to the gateway acquisition module and the data transmission module.

[0014] A method for monitoring data in mining lithium battery locomotives includes the following steps: The system collects multi-source locomotive data from mining lithium battery locomotives, parses the multi-source locomotive data by setting a collection and parsing protocol algorithm, and then performs data verification and preprocessing in sequence to output standardized multi-source locomotive signals. According to the preset data encapsulation rules, locomotive signals from different sources are integrated and encapsulated, and the encapsulated multi-source locomotive signals are transmitted through a wired communication link based on the communication protocol. The multi-source locomotive signals received by the communication port are encapsulated and decoded at the application layer according to the data frame header and data type. The decoded locomotive signals are then visualized and stored. The decoded locomotive signals include total battery voltage, total current, remaining power, individual cell voltage and temperature, and abnormal warning information. Based on the decoded locomotive signal, corresponding acquisition and control commands are generated according to the operating conditions of the mine locomotive.

[0015] III.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] This invention discloses a data monitoring device for mining lithium battery locomotives. The device utilizes a gateway acquisition module 3 to collect data from the locomotive via multiple protocols and interfaces, and a data transmission module 4 to enable bidirectional communication between the underground and surface environments. Based on the technical approach of various monitoring apps within the monitoring and display module 5, multiple sets of battery data input from the gateway can be integrated. The gateway acquisition module 3 transmits multi-source, multi-type native data via a wired network. The apps acquire data through listening ports, parse it according to data type and data frame headers, and then display and upload the parsed data. The host computer module 6 dynamically adjusts the acquisition strategy based on the locomotive's operating conditions, reducing redundant data, enhancing the system's environmental adaptability, and improving the real-time performance and accuracy of the monitoring data.

[0019] like Figure 1As shown, this invention discloses a mining lithium battery locomotive data monitoring device, which includes: a gateway acquisition module 3, a data transmission module 4, a monitoring and display module 5, a host computer module 6, and a power supply module 7. The gateway acquisition module 3 is used to collect multi-source locomotive data from the underground lithium battery locomotive 1 and the lithium battery monorail crane 2. The gateway acquisition module 3 includes an RS485 interface, a CAN interface, and a switch interface, and is configured with a data acquisition and parsing protocol algorithm. According to the communication protocol of the access device, the acquired multi-source locomotive data is parsed, verified, and preprocessed, and then a standard multi-source locomotive signal is output.

[0020] The data transmission module 4 is used to receive standard multi-source locomotive signals, integrate and encapsulate locomotive signals from different sources according to preset data encapsulation rules, and send the encapsulated multi-source locomotive signals to the monitoring and display module 5 through a wired communication link based on the communication protocol.

[0021] The monitoring and display module 5 includes a tablet terminal and a monitoring application running on it. Each monitoring application in the monitoring and display module 5 listens to the encapsulated multi-source locomotive signals received through the communication port, and performs application-layer decoding on the multi-source locomotive signals according to the data frame header and data type. The decoded locomotive signals are then visualized, displayed, and stored. The decoded locomotive signals include the total battery voltage, total current, remaining power, individual cell voltage and individual cell temperature, as well as abnormal warning information.

[0022] Based on the decoded locomotive signal, the host computer module 6 generates corresponding acquisition control commands according to the operating conditions of the mine locomotive. The host computer module 6 then sends each acquisition control command back to the gateway acquisition module 3 through the data transmission module 4 to control the acquisition parameters of the gateway acquisition module 3. The acquisition parameters include the data acquisition frequency, acquisition channel start / stop, and acquisition data type.

[0023] The power supply module 7 includes a power conversion and isolation unit, which is used to draw power from the power supply of the mining lithium battery locomotive and provide a stable working power to the gateway acquisition module 3 and the data transmission module 4.

[0024] Specifically, the gateway acquisition module 3 collects multi-source locomotive data for mining lithium battery locomotives, including the underground lithium battery electric locomotive 1 and the lithium battery monorail crane 2. The multi-source locomotive data collected by the gateway acquisition module 3 includes the voltage parameters of the battery pack, the locomotive power parameters, and the acquisition environment parameters of the underground lithium battery electric locomotive 1 and the lithium battery monorail crane 2.

[0025] Furthermore, the gateway acquisition module 3 is configured with an acquisition and parsing protocol algorithm to parse multi-source locomotive data. The acquisition and parsing protocol algorithm uses a multi-protocol parsing library to match the communication baud rate and data frame format of RS485, CAN and switch signals of multi-source locomotives, thereby parsing the multi-source locomotive data.

[0026] like Figure 2 and Figure 3 As shown, in this embodiment, the battery data of the lithium battery electric locomotive 1 and the lithium battery monorail crane 2 are accessed to the gateway acquisition module 3 via CAN TX, CAN RX, or RS485 A6, RS485 B7. The gateway acquisition module 3 supports not only typical serial communication standards but also the serial communication network of a distributed control system. Through a custom built-in software protocol, and based on the stability of standard hardware interfaces, it achieves the acquisition of locomotive battery data from various types of locomotives. The gateway acquisition module 3 parses the multi-source locomotive data using an acquisition and parsing protocol algorithm. This algorithm matches the communication baud rate and data frame format of RS485, CAN, and switch signals using a multi-protocol parsing library, thereby parsing the multi-source locomotive data.

[0027] Furthermore, the gateway acquisition module 3 preprocesses the multi-source locomotive data and outputs standard multi-source locomotive signals; the gateway acquisition module 3 sets a preset filtering threshold for the multi-source locomotive signals to filter out misaligned, jump-related, and invalid data in the multi-source locomotive signals, and filters out multi-source locomotive data that is not greater than the preset filtering threshold, and outputs standard multi-source locomotive signals.

[0028] like Figure 3 As shown in this embodiment, the acquisition gateway module is equipped with RS485, CAN, and digital input interfaces, covering the current mainstream technology routes. The acquisition gateway module is equipped with a protocol parsing algorithm, which can flexibly adapt to the protocol parsing algorithm and be compatible with and adapt to parsing different acquired data. The gateway acquisition module 3 transmits data through RS485 or CAN communication protocols and transmits the status of the mining lithium battery locomotive through digital inputs. Then, the gateway acquisition module 3 preprocesses the acquired multi-source locomotive signals and outputs standard multi-source locomotive signals.

[0029] Furthermore, the data transmission module 4 receives standard multi-source locomotive signals. The data transmission module 4 is equipped with RS485 and CAN communication protocols. The data transmission module 4 divides the multi-source locomotive signals according to the attributes of locomotive parameters through the communication protocols, splices locomotive data with the same attributes, and merges and encapsulates locomotive signals from different acquisition sources.

[0030] In this embodiment, the data transmission module 4 receives multi-type lithium battery data preprocessed by the acquisition gateway module, divides the multi-source locomotive signals into three categories according to parameter attributes: status data, fault alarm data, and identification data, and stores them in the corresponding data buffer queues to prevent confusion in the division of multi-source locomotive signals.

[0031] The multi-source locomotive signals are calibrated according to the time sequence of acquisition. The status parameters, fault codes, and equipment identifiers at the same time point are associated and spliced ​​to form a complete data record containing locomotive identifiers, locomotive status, and locomotive faults. The merged multi-source locomotive signals are sorted and encapsulated according to the time sequence, and then the merged and encapsulated multi-source locomotive signals are transmitted.

[0032] Furthermore, the monitoring and display module 5 acquires the locomotive signals merged and encapsulated by the data transmission module 4, receives the locomotive signals through the listening port in the tablet computer, and parses the frame headers of the multi-source locomotive signals according to the data type of the multi-source locomotive signals, and displays the parsed locomotive signals on the display screen in the tablet computer.

[0033] like Figure 4 As shown, in this embodiment, the monitoring and display module 5 receives parameters such as locomotive identification, locomotive status, and locomotive faults from multi-source locomotive signals via the USB port of the tablet computer. The USB port parses the frame headers of the multi-source locomotive signals according to their data types and displays the locomotive identification, locomotive status, and abnormal warning information of the mining lithium battery locomotive of the coal mine locomotive battery monitoring system on the display screen of the tablet computer. The locomotive identification in the decoded locomotive signals of the mining lithium battery locomotive includes the vehicle number; the locomotive status includes the total battery voltage, total current, remaining charge, single cell voltage, and single cell temperature; and the locomotive abnormal warning information includes total voltage too high, total voltage too low, communication disconnection, temperature too high, and charging overcurrent.

[0034] Furthermore, the host computer module 6 receives the parsed locomotive signal and transmits it in reverse to the data transmission module 4 to control the logic of the gateway acquisition module 3 to collect multi-source locomotive signals. The processed multi-source locomotive signals are then uploaded to the monitoring and display module 5 via wireless signal. The host computer module 6 controls the monitoring and display module 5 to display the processed multi-source locomotive signals, thereby monitoring the data of the mining lithium battery locomotive in real time.

[0035] like Figure 5 As shown, in this embodiment, the host computer module 6 receives the decoded locomotive signal and transmits it in reverse to the data transmission module 4 to control the gateway acquisition module 3 to acquire multi-source locomotive signals. This enables the data transmission module 4 to acquire data bidirectionally, thereby more accurately monitoring the multi-source locomotive data of the mining lithium battery locomotive. The processed multi-source locomotive signals are then uploaded to the monitoring and display module 5 via 4G, 5G, or Wi-Fi 6 wireless signals in the mine. The host computer module 6 controls the monitoring and display module 5 to display the processed multi-source locomotive signals, thereby monitoring the data of the mining lithium battery locomotive in real time. The monitored data includes individual cell voltage, individual cell temperature, and alarm information.

[0036] Meanwhile, the host computer module 6 controls and monitors the display module 5 to display information about malfunctions in the mining lithium battery locomotive. When the locomotive experiences excessively high total voltage, the host computer module 6 controls and monitors the display module 5 to display an alarm indicating excessively high total voltage; when the locomotive experiences excessively low total voltage, the host computer module 6 controls and monitors the display module 5 to display an alarm indicating excessively low total voltage; when the locomotive experiences a communication disconnection, the host computer module 6 controls and monitors the display module 5 to display an alarm indicating a communication disconnection; when the locomotive experiences excessively high temperature, the host computer module 6 controls and monitors the display module 5 to display an alarm indicating excessively high temperature; when the locomotive experiences charging overcurrent, the host computer module 6 controls and monitors the display module 5 to display an alarm indicating excessively high charging current. By displaying the information of the mining lithium battery locomotive through the monitoring and display module 5, the host computer module 6 monitors the data of the mining lithium battery locomotive in real time, thereby realizing real-time monitoring and precise control of the mining lithium battery locomotive data.

[0037] This invention discloses a data monitoring method for mining lithium battery locomotives. The method involves collecting multi-source locomotive signals from the mining lithium battery locomotives, parsing the multi-source locomotive data by setting a collection and parsing protocol algorithm, performing data verification and preprocessing sequentially, and outputting standardized multi-source locomotive signals. The locomotive signals from different collection sources are integrated and encapsulated according to preset data encapsulation rules, and the encapsulated multi-source locomotive signals are transmitted through a wired communication link based on a communication protocol.

[0038] By listening to the encapsulated multi-source locomotive signals received through the communication port, and performing application-layer decoding on the multi-source locomotive signals according to the data frame header and data type, the decoded locomotive signals are visualized and stored. The decoded locomotive signals include total battery voltage, total current, remaining power, individual cell voltage and individual cell temperature, as well as abnormal warning information. Based on the decoded locomotive signals, corresponding acquisition and control commands are generated according to the operating conditions of the underground locomotive.

[0039] This invention's gateway acquisition module 3 collects multi-source locomotive data from mining lithium battery locomotives. After parsing, data verification, and preprocessing using a parsing protocol algorithm, it generates standardized multi-source locomotive signals. The data transmission module 4 merges and encapsulates these multi-source locomotive signals. The monitoring and display module 5 parses the encapsulated multi-source locomotive signals and displays the decoded signals. The host computer module 6 transmits the decoded locomotive signals back to the data transmission module 4 to control the acquisition strategy of the gateway acquisition module 3 and monitor the mining lithium battery locomotive data in real time. This invention achieves bidirectional communication between underground and surface environments, dynamically adjusts the acquisition strategy based on locomotive operating conditions, reduces redundant data, enhances communication adaptability in the underground mining environment, and improves the real-time performance and accuracy of monitoring data.
