Description

Technical Field

[0001] This invention relates to the field of sensor data acquisition technology, and in particular to a universal sensor data acquisition device with self-locking clamping. Background Technology

[0002] After the sensors are manufactured, they need to be tested and data is collected. Sensor data collection refers to the acquisition of analog or digital signals collected by the sensor under test and sending them to the host computer for analysis and processing.

[0003] However, the wiring terminals of different sensors vary, making the connection to the data acquisition device cumbersome. The current method involves manually connecting each sensor terminal to the data acquisition device one by one using wire clamps, and then disconnecting the connection after testing. This method has the following drawbacks:

The wire clamps are also prone to contact with each other, which can cause short circuits and result in inaccurate data acquisition from the sensor. 2.
