Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0041]A hand-held online relay tester for electrical equipment, mainly with a main control unit as the core of the tester, wherein the main control unit is respectively connected to a display unit, a power supply unit, a battery power detection unit, a data download unit and an isolation unit, The peripherals such as the acquisition unit, the power supply unit, the key unit and the buzzer are respectively connected through the isolation unit.

[0042] The main control unit is the brain of the relay online tester and the core of the entire test instrument. The main control unit uses the mainstream ARM STM32 processor as the main control component, and builds accurate measurement / test circuits through it, including 16bit AD analog acquisition circuit, digital-to-analog converter TLV5618 and analog-to-digital converter ADC conversion circuit, coil micro-resistan...

Abstract

The invention relates to a handheld power equipment relay online tester and a test method, the handheld power equipment relay online tester comprises a relay body, the relay body comprises a main control unit, and the main control unit is respectively connected with a display unit, a data downloading unit and a battery electric quantity detection unit; and the main control unit is respectively connected with the acquisition unit, the power supply unit, the key unit, the buzzer and other peripherals through the isolation unit. According to the invention, the ARM is used as a test core processor, a traditional measurement circuit built by a relay and a contactor is abandoned, the innovative test method can dynamically monitor and forecast the fault state of the relay in a working state, andonline display or offline analysis of a test curve can be realized. A lithium battery power supply handheld structure is adopted for device power supply, online analysis of fault conditions and reasons of the relay is achieved, and timely judgment of relay faults is facilitated.

Description

technical field [0001] The invention relates to the technical field of on-line testing, in particular to a hand-held on-line tester for electrical equipment relays and a testing method. Background technique [0002] As a basic component, electromagnetic relay is widely used in control fields such as automobile safety automatic control system, machine production equipment, household appliances, rail transit electrical equipment, etc. The role of toggles and switches. The quality of the electromagnetic relay directly affects the accuracy, reliability and safety of the control system, so it is of great significance to regularly detect its electrical characteristics. Especially for relays on aircraft and military equipment, relays play a vital role in the normal operation and safety of the entire electronic system. Therefore, these industries with high safety requirements have very high reliability requirements for electromagnetic relays, and the quality inspection before leav...
