Embodiment Construction

[0030]In the research, it is found that the high-precision positioning motherboard chip is cumbersome to operate in the early stage of commissioning. Generally speaking, the relative distance between the positioning information receiving device (such as the vehicle display screen) and the motherboard chip is relatively long, so the serial port is placed on the motherboard chip. The signal is converted to RS232 level for transmission; however, since the commissioning computer (a kind of commissioning equipment) does not have an RS232 interface, it is currently a USB interface; a feasible solution is to connect an external USB-to-serial board, which requires commissioning When disconnecting the serial transceiver line on the motherboard, the flying wire is connected to the external serial port board. However, in the above commissioning operation, not only the circuit on the motherboard chip needs to be disconnected, but also an external circuit needs to be connected. In the commi...

Abstract

The disclosure relates to a positioning circuit supporting commissioning, a commissioning control method, an electronic device and a vehicle, which can be applied to the field of unmanned / automatic driving vehicles. to output positioning information; the first conversion interface and the second conversion interface connected to the main control unit, the first conversion interface is used to connect the main control unit and the positioning information receiving device, and the second conversion interface is used to connect the main control unit and commissioning equipment; and a switching selection unit, which is arranged on the signal transmission path between the main control unit and the first conversion interface and the second conversion interface; wherein, the control terminal of the switching selection unit is used to receive the switching control signal from the main control unit, Based on the switching control signal, the switching selection unit switches between the input signal of the first conversion interface being connected to the main control unit and the input signal of the second conversion interface being connected to the main control unit. The above circuit is convenient for commissioning, simple and practical.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle positioning and commissioning, and in particular to a positioning circuit supporting commissioning, a commissioning control method, electronic devices, and a vehicle. Background technique [0002] In the field of vehicles, especially for unmanned / autonomous driving vehicles, it is very important to achieve accurate positioning of vehicle location information. [0003] At present, there are many high-precision positioning chips / systems applied to the field of automatic driving. The high-precision positioning motherboard chip receives the navigation signal of the global navigation satellite system (GNSS, global navigation satellite system) and demodulates the navigation signal based on the built-in algorithm. Output positioning coordinates and time information through Universal Asynchronous Receiver / Transmitter (UART, Universal Asynchronous Receiver / Transmitter). Generally speaking, the re...
