Batch calibration device

The utility model discloses a batch calibration device, which comprises a calibration box, a plurality of calibration plates are arranged in the calibration box, at least two sensor modules are inserted on each calibration plate, and the calibration plates are externally connected with an upper computer and power supply voltage; the calibration board performs format conversion on a bus signal output by the upper computer, transmits the bus signal to each sensor module, and performs synchronous calibration on parameters of each sensor module; the calibration board also collects and stores parameter data of each sensor module, converts the format of the parameter data into a bus signal, and then uploads the bus signal to the upper computer for storage and display. A plurality of sensor modules can be connected at the same time, synchronous calibration is carried out on the plurality of sensor modules, and the problem that existing calibration equipment cannot calibrate sensors in batches at the same time is sol
