Electrical system for intelligently detecting operation frequency of proximity switch

Abstract

The invention relates to an electrical system for intelligently detecting the operation frequency of a proximity switch. The electrical system comprises a target rotary table, an upper computer, a PLC, a frequency converter, an adjustable-speed motor, a rotating speed and frequency measuring device and a sample locating and clamping mechanism. The PLC is connected with the upper computer, the frequency converter and the sample locating and clamping mechanism. The frequency converter, the adjustable-speed motor and the target rotary table are sequentially connected. The proximity switch is connected with the target rotary table. The rotating speed and frequency measuring device is connected with the proximity switch. The proximity switch is fixed to the target rotary table. After receiving commands from the upper computer, the PLC converts the commands into corresponding time sequence signals to control the frequency converter, so that speed adjustment of the adjustable-speed motor is achieved. The adjustable-speed motor drives the target rotary table to rotate, so that the proximity switch continuously moves and makes responses, and the response frequency of output signals is measured through the rotating speed and frequency measuring device. Compared with the prior art, the electrical system has the advantages of being stable in operation, high in reliability, intelligent and the like.

Description

technical field [0001] The invention relates to a proximity switch detection system, in particular to an electrical system for intelligent detection of the proximity switch operating frequency. Background technique [0002] Low-voltage electrical appliances are an important part of the electrical industry. In the manufacturing process, they mainly play the roles of switching, control, protection, detection, indication and alarm. It directly reflects the advanced manufacturing industry and equipment automation level of a country. From 2006 to 2010, my country's annual power generation capacity increased by 66-77 billion kW·h, and the average annual installed capacity was about 21GW. For every 10,000 KW power generation equipment added, about 40,000 pieces of various low-voltage electrical components and According to the matching calculation, 84 million low-voltage electrical appliances need to be added every year. It can be seen from it that the next few years will be an oppo...

Problems solved by technology

[0004] At present, the detection system of low-voltage electrical appliances generally adopts manual operation, the type is single, and the detection results are difficult to control

This is indeed a good choice when there are not many types and quantities of voltage electrical appliances, but with the continuous increase in the types of low-voltage electrical appliances and the increasingly stringent
