Automatic detection tool of micro-power wireless module

Abstract

The invention discloses an automatic detection tool of a micro-power wireless module. An MCU is separately connected with a power module, an RTC and battery module, an indication module, a control button and function selection switch module, a DUT power control and static current detection circuit, a tested module and a standard module; a 60dB radio frequency attenuator is separately connected with the tested module and the standard module; the standard module is used for setting a reference signal, transmitting the reference signal to the tested module and receiving a signal returned by the tested module; and the 60dB radio frequency attenuator is used for adjusting the reference signal to a signal intensity level required by the sensitivity of the tested module and attenuating the signal returned by the tested module. The automatic detection tool disclosed by the invention adopts the technology of detecting the tested module by using the standard module and bidirectionally adjusting the amplitude of the signal to the required intensity level by using the attenuator, and thus high-efficiency detection is realized; and moreover, the operation is simple, and an operator only needs to press a ''start test button'' and observe red and green light-emitting diodes more than ten seconds later to obtain a test result, thereby saving time and saving labor.

Description

technical field [0001] The invention belongs to the technical field of automatic detection, in particular to an automatic detection tool for a micro-power wireless module. Background technique [0002] The low-voltage meter reading system is divided into two types according to the meter reading communication method: wired and wireless. The main solutions are: RS485 meter reading system, low-voltage power line carrier meter reading system, wireless meter reading system, hybrid meter reading system, and plastic optical fiber meter reading system. These two types of meter reading systems have their own advantages and fields of application. [0003] In recent years, low-voltage power line carrier meter reading has occupied the mainstream position, and some achievements have been made in large-scale field application, read-through, stability and real-time performance, but there are deficiencies: the environment of low-voltage distribution network is complex, the interference is l...

Problems solved by technology

[0003] In recent years, low-voltage power line carrier meter reading has occupied the mainstream position, and some achievements have been made in large-scale field application, read-through, stability and real-time performance, but there are deficiencies: the environment of low-voltage distribution network is complex, the interference is large, and the low-voltage power line It is difficult for the carrier to guarantee the stability of its meter reading

[0007] (2) The meter may increase or decrease according to the demand, or the connection of nodes may be affected by the environment. In the application of meter reading, the micro-power wireless network must be a dynamic network, which requires dynamic system reconfigurability;

These instruments are bulky, expensive, expensive to maintain, complex to operate, and slow to detect
