As shown in fig. 1, a CPR feedback pad calibration system comprises a CPR feedback pad calibration instrument and an industrial personal computer, wherein the industrial personal computer comprises test software for sending a test instruction and judging data, the calibration instrument is used for receiving the test instruction and acquiring data inside the CPR feedback pad, the calibration instrument comprises a USB seat and a connector, the calibration instrument is connected with the industrial personal computer through the USB seat and a USB cable, the calibration instrument is connected with the CPR feedback pad through the connector and the test cable, and the calibration instrument further comprises a microcontroller for calibrating system errors of a CPR feedback pad acceleration sensor and a conditioning circuit.
Specifically, when a test is needed, a tester connects a CPR feedback pad to a calibrator through a test cable, the calibrator is connected to an industrial personal computer through a USB cable, the tester clicks a screen of the industrial personal computer to inform the calibrator to prepare calibration, the tester inputs an ID number of a product to be tested, a calibration system starts calibration work, the industrial personal computer sends a test instruction to the calibrator, the calibrator sends a test signal to the CPR feedback pad after receiving the test instruction and is connected with a nonvolatile memory inside the CPR feedback pad through the test cable, a microcontroller of the calibrator writes a standard datum into each memory cell of the nonvolatile memory, reads a datum from the nonvolatile memory, and compares whether the written datum and the read datum are consistent to obtain a test result. If the written data and the read data are not consistent, the test result is that the CPR feedback pad nonvolatile memory is unqualified, the test is stopped, and a tester is informed, if the test result is consistent, the CPR feedback pad nonvolatile memory is qualified, and the CPR feedback pad acceleration sensor is further tested by the calibration system. The written standard data can be set by a tester according to actual conditions.
The acceleration sensor inside the CPR feedback pad is influenced by gravity with a fixed gravitational acceleration when placed statically horizontally, the value is about equal to 1g, after the calibration system obtains the result that the CPR feedback pad nonvolatile memory test is qualified, informing a tester to horizontally place the front side and the back side of the CPR feedback pad respectively, outputting voltage signals with the z-axis acceleration respectively corresponding to +1g and-1 g by the CPR feedback pad, amplifying the voltage signals by a conditioning circuit in the CPR feedback pad, connecting the CPR feedback pad to a calibrator by a test cable, collecting acceleration data when the CPR feedback pad is placed on the front side and acceleration data when the CPR feedback pad is placed on the back side, and transmitting the acceleration data to an industrial personal computer, and judging whether the acceleration data when the front side is placed and the acceleration data when the back side is placed are both within a standard error range by the industrial personal computer to obtain a test result.

Wherein the standard error can be set by a tester according to specific conditions.
When the acceleration sensor inside the CPR feedback pad is placed in a static horizontal state, the output signal is theoretically equal to +1g or-1 g, but due to factors such as manufacturing errors of the acceleration sensor, installation errors on a PCB (printed circuit board), zero errors of a conditioning circuit and the like, the output signal is often deviated, and the correct judgment of a CPR host computer is influenced, so that the system error of the CPR feedback pad needs to be calibrated.
