Method for rapidly testing crimping state of network cable crystal head based on capacitance measurement

Abstract

The invention belongs to the technical field of network cable crystal head crimping test, and particularly relates to a network cable crystal head crimping state rapid test method based on capacitance measurement, and the method comprises the following operation steps: S1, when the test starts, a microprocessor is continuously in a low power consumption mode, and when a watchdog module of the microprocessor reaches a set time, the microprocessor starts to be awakened; s2, enabling the U3 and the U12 by the microprocessor, setting the U12Z to be in a high level, controlling a capacitor of a to-be-measured channel to start charging at the moment, supplying the U3EN / U12EN to be in a low level so as to enable the U3 / U12, setting a port of the microprocessor connected with the U3Z to be an input interruption trigger source, and setting the U30-U3M to be matched with a port to be measured. The connection state of one end of the network cable can be obtained at a speed which is not perceived by a tester, the test can be carried out without waiting for the two ends to be well done, the module is low in power consumption and miniaturized, and can be embedded into a network cable clamp, so that a user can immediately know whether the network cable is successfully crimped or not.

Description

Technical field [0001] The invention relates to the technical field of network cable crystal head crimping testing, and is specifically a rapid testing method for the network cable crystal head crimping state based on capacitance measurement. Background technique [0002] The crystal head is an important interface device in network connections. It is a plastic connector that can be inserted in a fixed direction and automatically prevents it from falling off. It is used for network communications. The crystal head is a plastic connector that can be inserted in a fixed direction and automatically prevents it from falling off. Its appearance is crystal clear. The crystal head is suitable for on-site termination of equipment rooms or horizontal subsystems. The shell material is made of high-density polyethylene. Both ends of each twisted pair are connected to the network card and hub through the installation of crystal heads. There are two types of network cable crystal heads. T...

Problems solved by technology

[0003] In the existing home improvement market, the main method to test whether the crystal head of the network cable is crimped is to use a cable tester to test after the two ends of the cable are crimped. The reed and the reed are not well crimped, or the position of the inner core of the reed is not well adjusted, resulting in no connection between the core and the reed
