Embodiment 2

[0021] The circuit principle and debugging method of the second embodiment are the same as those of the first embodiment.

[0022] The debugging device of the two-way host radio frequency board of the vehicle remote control system of the present invention, embodiment three is applicable to the two-way host radio frequency board of SXTX-A type and SXTX-C type, as image 3 As shown, the difference between it and Embodiments 1 and 2 is only that the linked selection switch S3 is used, so that it can be respectively applied to SXTX-A type and SXTX-C type two-way host radio frequency boards. The circuit principle and debugging method of the third embodiment are the same as those of the first and second embodiments.

[0023] In the present invention, the CPU chip U1 continuously outputs the frequency deviation signal, and the two-way host radio frequency board of the vehicle remote control system does not need an interval time during debugging, and both the transmitting debugging an...

Abstract

The invention discloses a debugging device for a bidirectional host radio frequency board of a vehicle remote control system, which comprises a power supply part, a CPU (Central Processing Unit) chip, a peripheral circuit of the CPU chip, a selective switch, an output interface and a comprehensive test instrument, wherein the power supply part supplies a working power supply to the CPU chip; the comprehensive test instrument is connected to an antenna end of the bidirectional host radio frequency board; a frequency offset output end of the CPU chip is connected to a frequency offset output pin of the output interface; the output interface is provided with a transmitting and receiving control pin which is connected to a transmitting and receiving control end of the host radio frequency board; and the selective switch is connected with the transmitting and receiving control pin of the output interface and used for selecting a transmitting and receiving mode of the transmitting and receiving control pin. In the invention, compared with the prior art, the CPU chip constantly outputs frequency offset signals, and no interval time is needed when the bidirectional host radio frequency board of the vehicle remote control system is debugged, no matter transmission debugging or receiving debugging can be completed in one step, therefore, the working efficiency is greatly improved, and aworker can debug 250-300 boards per day.

Description

technical field [0001] The invention relates to a circuit debugging device, in particular to a debugging device for a bidirectional host radio frequency board of a vehicle remote control system. Background technique [0002] In the prior art, when debugging the radio frequency board of the two-way host of the vehicle remote control system, it can only be debugged by connecting to the alarm host, and the transmission and reception have to be debugged separately. When launching and debugging, first trigger the remote control button on the alarm host to make the radio frequency board of the two-way host start to transmit. The comprehensive tester connected to the antenna end of the radio frequency board of the two-way host displays the frequency and frequency deviation of the transmission, and adjusts the radio frequency of the two-way host with a pen. The emission control on the board can adjust the capacitor to the required frequency. The time for each emission of the two-way...
