Description

Technical Field

[0001] This invention belongs to the technical field, and specifically relates to an intelligent vehicle-mounted combined device for underground mining. Background Technology

[0002] Underground transport vehicles include mine cars, flatbed cars, material cars, and other specialized vehicles. In underground coal mine production, vehicles used for supporting personnel and transporting coal generally operate along long routes. In the complex and confined environment of the tunnels, if the transport process is not smooth and there is a lack of necessary and effective auxiliary vehicle equipment, many tasks may be unable to be carried out normally.

[0003] With the continuous development of science and technology, improving the auxiliary on-board equipment of underground vehicles and enhancing their automation and intelligence levels plays a vital role in ensuring normal and safe production in mines.

[0004] Currently, the common approach is to fix an in-vehicle tablet computer (PAD) on the vehicle's dashboard. However, the PAD is a fixed-form in-vehicle device that cannot be removed for independent use, and its expansion capabilities are quite limited. Summary of the Invention

[0005] To address the aforementioned problems, the purpose of this invention is to provide an intelligent vehicle-mounted combined device for underground mining, which can meet the switching requirements between PAD vehicle environments and general applications. The base has communication and charging functions with the PAD, which can meet certain special application scenarios, such as mine personnel transportation, vehicle parameter reading, transportation positioning, etc. It can effectively serve as a data acquisition device, connecting the collected data to the PAD via a bus and displaying it centrally, avoiding wiring problems caused by repeated disassembly.

[0006] The technical solution of the present invention is: an intelligent vehicle-mounted combined device for downhole applications, comprising a vehicle-mounted base fixed to a vehicle and a PAD connected to the vehicle-mounted base via a USB Type-C connector, wherein the USB Type-C connector comprises:

[0007] The charging cable includes a connecting wire connected to the car's 12V power supply module, a DC-DC voltage regulator chip connected to the connecting wire, and a USB cable connected to the DC-DC voltage regulator chip. The USB cable is connected to the PAD charging interface. The DC-DC voltage regulator chip can convert the 12V voltage of the car's 12V power supply module to 5V voltage.

[0008] The USB signal cable is extended into four USB interfaces through a USB hub. Two of them use USB to network card chips to realize external Ethernet function; one uses USB to UART chip, and then performs level conversion through TTL to RS-232 to expand into a standard serial port; the last one retains solder points as test points or to connect a USB flash drive interface.

[0009] The serial port signal line includes a UART to CAN bus capable of acquiring the TTL UART serial port signal output by the PAD, and a connector connected to the UART to CAN bus via a CAN bus protection and matching circuit. The connector is connected to the device to be detected or communicated with, enabling the PAD to acquire data from the device to be detected or communicated with in real time.

[0010] The IIC signal line includes a button I / O interface that is extended from the IIC bus through an expansion chip. The button I / O interface is connected to multiple buttons, which are mounted on the base.

[0011] The MIC audio input signal line includes a MIC voice signal line connected to the PAD and a hand microphone interface connected to the MIC voice signal line through a voice matching circuit, wherein the hand microphone interface is plugged into a hand microphone.

[0012] The vehicle base is provided with a guide groove, and the PAD is movably inserted into the guide groove. The back of the vehicle base is provided with screw holes, and the vehicle base is fixed to the vehicle with screws.

[0013] The charging cable conforms to the BC1.2 charging specification, can meet the charging requirements of different platforms / protocols, and supports 15W fast charging.

[0014] The USB-to-network adapter chip is used to connect Ethernet interface devices, such as network cameras, routers, and switches.

[0015] The USB to UART chip can serve as the debugging information printing interface for the entire system, facilitating the handling of problems during development; it can also connect to MODBUS bus devices to enable data reading from external devices.

[0016] Furthermore, the PAD terminal includes a reading module, an algorithm generation module, and a parsing module. The reading module can open the serial port according to the baud rate of the corresponding manufacturer's protocol, read the serial port input stream data in a loop, convert the byte array into hexadecimal data, and pass it to the parsing module for parsing. The algorithm generation module can generate the corresponding parsing algorithm for the currently configured vehicle manufacturer based on the configured vehicle manufacturer's protocol parameters, which include the manufacturer name, baud rate, message format (2.0B standard frame and extended frame), message identification code MESSAGEID, parameter name, and parameter byte size. The parsing module can parse and obtain various ECU parameters, including vehicle speed, engine speed, mileage, water temperature, gauge temperature, and methane concentration data, based on the parsing algorithm class generated by the algorithm module, and update them to the required page in real time.

[0017] The PAD can solve the problem of data parsing and adaptation under different vehicle manufacturers and different ECU protocols. It can dynamically configure and generate the required protocol parsing algorithm on the PAD according to the format of the manufacturer's protocol. Thus, it can perfectly adapt to the protocols of all vehicle manufacturers that support CAN bus without making any changes to the PAD, and read the ECU data of any vehicle that supports CAN communication.

[0018] The vehicle-mounted base is also equipped with a UWB positioning module, which, in conjunction with the UWB coverage scenario in underground coal mines, can accurately obtain the location of the equipment.

[0019] The working principle of this invention is as follows: Through a combination of various circuits and interface protocols, it achieves BC1.215W charging, UWB positioning, and connections with the vehicle via UART, CAN bus, ECU, and Ethernet. Simultaneously, it connects the tablet to the vehicle dock through a Type-C interface and a USB Type-C connector, transmitting vehicle signals to the tablet via USB, UART, and IIC protocols, enabling the tablet to analyze vehicle data and control the vehicle.

[0020] Compared with existing technologies, the advantages of this invention are: it can meet the switching needs between PAD in-vehicle environments and general applications. The base has communication and charging functions with the PAD, which can meet certain special application scenarios, such as mine personnel transportation, vehicle parameter reading, transportation positioning, etc. It can also serve as a data acquisition device to connect the collected data to the PAD via a bus and display it centrally, avoiding wiring problems caused by repeated disassembly.

[0034] The PAD can solve the problem of data parsing and adaptation under different vehicle manufacturers and different ECU protocols. It can dynamically configure and generate the required protocol parsing algorithm on the PAD according to the format of the manufacturer's protocol.
