Embodiment Construction
[0010] The present invention will be further described below in conjunction with the accompanying drawings.
[0011] Such as figure 1 Shown is a test device for simulating a real sensor, including a PC host, a controller, and an analog sensor. The PC host is connected to the controller through an RS-232 interface, and the controller is connected to the analog sensor. The controller is a single-chip microcomputer. It also includes a parking radar ECU (Electronic Control Unit), which is connected to an analog sensor. Simulate real sensors through single-chip control, and can simulate 1-4 at the same time.
[0012] The test device for simulating a real sensor provided by the present invention, the reversing radar sensor simulation system mainly simulates the sensor by the host computer software through the RS-232 interface and the test device communication, and the corresponding waveform generated by the simulation of the measuring tool device is sent to the reversing radar hos...

The invention discloses a testing device of simulating a real sensor. The testing device of simulating the real sensor comprises a personal computer (PC) host machine, a controller and an analog sensor, wherein the PC host machine is connected with the controller through a RS-232 connector, and the controller is connected with the analog sensor. The controller is a single chip microcomputer and further comprises a reverse sensor electronic control unit (ECU), and the reverse sensor ECU is connected with the analog sensor. The testing device of simulating the real sensor achieves residual vibration division of the analog sensor through the single chip microcomputer, and has the advantages that residual vibration split points can be flexibly chosen in the residual vibration range of the sensor, an arbitrary split point can be adjusted with a needed split width in the residual vibration range of the sensor, an echo with arbitrary width can be given in an arbitrary distance, states of a reverse sensor in different severe environments can be simulated, help and convenience are provided for achieving the reliability and stability of the system, and the testing device of simulating the real sensor can be used in each stage such as development, test, and analysis for bad of products.
