Device for detecting matching relationship of radio remote control device and method thereof

Abstract

The invention provides a matching relation detection device and method for detecting the matching relation between a transmitting end and a receiving end of a radio remote control device, and the detection device comprises a signal receiving unit which is configured to receive a wireless signal transmitted by the transmitting end of the remote control device; the interface unit is configured to provide an interface connected with the chip to be detected extracted from the receiving end of the detection remote control device; and a processor configured to perform control so as to provide power for the chip to be tested through the interface unit and detect signal changes of the chip pins from the chip to be tested, and when it is determined that the signal changes of the chip pins to be tested meet preset conditions corresponding to input of the transmitting end of the remote control device, the chip pins to be tested are transmitted to the remote control device. And determining that the transmitting end and the receiving end of the remote control device have a corresponding matching relationship.

Description

technical field [0001] The invention relates to the field of radio matching relationship detection, in particular to a device and method for detecting the matching relationship between a transmitter and a receiver in a radio remote control. Background technique [0002] For a long time, according to practice, the scope of inspection for electronic remote control explosive devices (electronic remote control arson devices) includes electronic remote control device inspection, charge (fire, explosive) inspection and other criminal technical explosion experiments. [0003] However, if the matching relationship between the signal receiving end of the electronic remote control device and the signal transmitting end (remote control) of the electronic remote control device is not checked, it cannot be confirmed that the receiving end of the electronic remote control device involved and the transmitting end of the electronic remote control device cannot be verified. This will make th...

AI Technical Summary

Problems solved by technology

However, if the receiving end of the remote control device cannot work normally, it is impossible to verify whether there is a matching relationship between the receiving end and the transmitting end.

[0005] However, in practice, because the receiving end of the electronic remote control device has exploded, or the electronic remote control explosive device that has not exploded is treated with water cannon to destroy the key parts (signal receiving end and power supply of the electronic remote control device), resulting in remote control The receiving end of the device cannot work under normal conditions, making it impossible to verify whether the receiving end and the transmitting end are compatible

[0006] In addition, since the receiving end of the electronic remote control device has been destroyed, the chip model in the receiving end may not be known

In this case, it is difficult to determine the specific access pin of the wireless signal on the chip

In addition, there may be other enabling signals in the chip under test. It is difficult to detect whether there is a matching relationship between the transmitting end and the receiving end when the related signals cannot determine their functions.
