Description

Technical Field

[0001] The utility model relates to the technical field of unmanned mining trucks, and in particular to a combined navigation group management system applied to unmanned mining trucks. Background Art

[0002] The combined navigation system of unmanned mine vehicles directly affects the driving safety and production efficiency of the mine vehicles. During the production and operation of the unmanned transportation system in open-pit mines, due to the large mining area, complex operating environment and collaborative operation of multiple vehicles, the positioning information of all unmanned mine vehicles needs to be remotely monitored and managed in the background.

[0003] Traditional technology provides differential signals to the combined navigation equipment of unmanned mining vehicles through the built-in radio by logging into the Qianxun account. However, this can only achieve high-precision positioning of a single vehicle, and cannot monitor the real-time positioning information of all vehicles when multiple vehicles are working together. It is difficult to achieve unmanned detection and management of different combined navigation equipment of multiple vehicles at the same time.

[0004] It can be seen that it is very important to study a system for unmanned mining vehicles that can realize unmanned detection and management of different combined navigation devices of multiple vehicles at the same time. Utility Model Content

[0006] There are a plurality of mining trucks, each of which is equipped with a combined navigation device and a vehicle-mounted CPE, and the combined navigation device is communicatively connected with the vehicle-mounted CPE to report GPGGA data to the vehicle-mounted CPE; and

[0007] The RTK base station receives the GPGGA data reported by the vehicle-mounted CPE and outputs a differential signal, and is communicatively connected with the vehicle-mounted CPE. The vehicle-mounted CPE is communicatively connected with the combined navigation device to transmit the differential signal to the combined navigation device. The combined navigation device is communicatively connected with the mining card to input the positioning information of the combined navigation device to the mining card.

[0008] Furthermore, the integrated navigation device and the vehicle-mounted CPE are connected to each other through RS232 communication protocol.

[0009] Furthermore, the vehicle-mounted CPE and the RTK base station are connected to each other in a wireless communication manner.

[0010] Furthermore, the combined navigation device and the mining card are connected via a CAN communication protocol.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model realizes high-precision positioning of unmanned mining trucks through the combination mode of RTK base station-vehicle-mounted CPE-combined navigation equipment, and can also manage the combined navigation group of multiple vehicles working together in open-pit mines in the background of RTK base station.

[0015] In order to make the technical scheme and technical effect of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments.

[0016] Example

[0017] like Figure 1 As shown, the utility model provides a combined navigation group management system for unmanned mining vehicles, including multiple unmanned mining vehicles 1 and RTK base stations 2, wherein each mining vehicle 1 is equipped with a combined navigation device and a vehicle-mounted CPE. The combined navigation device and the mining vehicle 1 communicate with each other through the RTK base station 2 and the vehicle-mounted CPE, and the status of the combined navigation device during the collaborative operation of multiple vehicles can be monitored and managed from the background of the RTK base station 2.

[0018] Specifically, the combined navigation device on the mining truck 1 is connected to the vehicle-mounted CPE through the RS232 communication protocol to report GPGGA data to the vehicle-mounted CPE. When multiple vehicles work together, different vehicle-mounted CPEs report their received GPGGA data to the RTK base station 2 through wireless communication.

[0019] RTK base station 2 receives and processes the GPGGA data reported by the vehicle-mounted CPE and outputs a differential signal, and RTK base station 2 sends the differential signal to the vehicle-mounted CPE by wireless communication; the vehicle-mounted CPE then sends the differential signal to the integrated navigation device through the RS232 communication protocol; the integrated navigation device outputs positioning information based on the differential signal and uploads it to the mining card 1 via the CAN communication protocol.

[0020] The utility model adopts the combination mode of RTK base station 2-vehicle-mounted CPE-combined navigation device, which can not only utilize the vehicle-mounted CPE to provide differential signals to the combined navigation device through an external radio station to achieve high-precision positioning of the mining truck 1, but also can monitor the positioning status of all vehicles in multi-vehicle collaboration in real time through the background of RTK base station 2, thereby realizing combined navigation group management of multi-vehicle collaborative operations in open-pit mines.
