Abstract

The invention provides a portable breaker contactor travel recorder and method based on a DSP and belongs to the technical field of electrical property monitoring. The portable breaker contactor travel recorder comprises a power supply module, a signal conditioning module, a gathering module, the DSP and a USB communication module. A contactor of a breaker is measured through an angle displacement sensor, and the defects that a straight line displacement sensor is large in size and limited by installation space and the installation position are overcome. The problems that the communication speed of an RS232 or the communication speed of an RS485 is limited, the transmission mode is simplex, and flexibility is poor are solved through the adoption of the USB communication module. According to a USB, the system has an intuitive port interface and good expandability and plug-and-play is supported, the DSP has capability of processing complex operation and can meet the requirement of a large amount of calculation required by a complex industrial environment. According to a brand new data transmission solution, a breaker contactor travel recording system is convenient to move and more flexible and more convenient to use.

Description

technical field [0001] The invention belongs to the technical field of electrical performance monitoring, and in particular relates to a DSP-based portable circuit breaker contact stroke recorder and a method. Background technique [0002] In the early traditional method of recording the contact travel of circuit breakers, maintenance testers used electric stopwatches, synchronous lights, light oscilloscopes, electromagnetic oscillators, and drum speedometers to conduct test records. These methods not only occupy a large area of ​​the site, the wiring and operation are complicated during the test, and the recorded data needs to be processed and calculated manually, but also the measurement error is large, the maintenance work takes a long time, and the equipment transportation is also difficult. On the other hand, because the original communication system mostly uses RS232 or RS485 communication, the maximum transmission distance of the serial port RS-232 is about 15m, the m...
