Embodiment Construction

[0031] A device for vehicle-mounted ATC system testing, including a platform, functional modules and external interface equipment,

[0032] 1. The platform is composed of three types of boards: main board, function board and IO board;

[0033] The main board is the core of the interface platform, and all function boards and IO boards are based on the expansion of this board and are allocated by this board.

[0034] Function board: The function board is fixed on the main board through the connector, which expands the external and internal communication functions of the main board, including RS232, CAN, RS422, RS485, etc. The current function board includes:

[0035] Function board-1: the board provides external CAN bus interface and external RS232 interface;

[0036] Function board-2: the single board provides external RS422 / RS485 serial bus;

[0037] Function board-MF: the board provides voltage / current loop acquisition interface, pulse acquisition interface, differential si...

Abstract

The invention belongs to the field of vehicle-mounted ATC systems and relates to a device for testing a vehicle-mounted ATC system. The device comprises a platform, a functional module and an externalinterface device. A flexible and convenient testing device environment is provided for testing of a vehicle-mounted device, a scene of real vehicle running can be simulated, multiple interface testscan be provided, a pre-emitting function of a transponder can simulate the function of beginning to transmitting signals of a transponder antenna in a real environment when it is monitored that a vehicle is located in a specific range, and analog simulation of vehicle-mounted communication mechanisms of front edges such as pulse signals and radar signals can be achieved. The vehicle-mounted devicecan complete debugging work before the device is online on the premise that a laboratory has no other real environment and has no device. In addition, the device has universality and can debug otherboards cards and interfaces similar to vehicle-mounted device and the like.

Description

technical field [0001] The invention belongs to the field of vehicle-mounted ATC systems, and relates to a device for testing the vehicle-mounted ATC system. Background technique [0002] The vehicle-mounted ATC system communicates with other external devices through signal pulse, CAN port communication, 422 / 485 serial port communication, 232 serial port communication, MVB communication, Ethernet communication, etc. Different communication methods correspond to different device functions. Therefore, in order to test the various functions of the on-board ATC system, multiple equipments are required to cooperate. For example: 1: Install the CAN communication software on the industrial computer through the CAN card. CAN communication is tested by sending CAN communication to the object under test from the industrial computer. 2: Install the MVB transceiver program on the industrial computer through the MVB box. MVB communication is tested by sending MVB information from the...
