Abstract

The invention discloses a motor fault monitoring and alarm device. The motor fault monitoring and alarm device includes a sensor module, a signal processing module, a main controller module, a sound alarm module and a wireless signal transmitting module; the sensor module is connected with the signal processing module; the signal processing module, thee sound alarm module and the wireless signal transmitting module are connected with the main controller module; the sensor module includes an electric energy sampling module, a temperature acquisition module and a humidity acquisition module; and the signal processing module comprises a filter circuit, a signal amplifying circuit and an A/D conversion circuit, wherein the filter circuit, the signal amplifying circuit and the A/D conversion circuit are connected with one another sequentially. The motor fault monitoring and alarm device has the advantages of simple structure and convenient use. With the motor fault monitoring and alarm device adopted, various parameters of a motor in operation can be well monitored, and when a fault occurs on the motor, workers can be prompted through the sound alarm module, and the wireless signal transmitting module can transmit wireless signals, so that warning can be performed.

Description

A kind of electrical fault monitoring and warning device

Technical field

The present invention relates to motor monitoring technical field, be specially electrical fault monitoring and warning device.

Background technology

Modern industry, agricultural or even commercial field, the use of motor is more and more frequent, but along with the development of chemical industry, oil and the every profession and trade such as electronics, auto industry automated control technology, product quality and production safety provide higher technical requirement to control procedure and opertaing device, reliable safety precautions to be implemented to production or equipment simultaneously, also must reach higher precision to the malfunction monitoring of equipment and the judgement of running status.Such as at field of central air-conditioning; to the state recognition of fan coil and industrial many grades of speed motors; for the safeguard protection of motor and equipment thereof; how to realize the accurate judgement of motor operating state and fault type thereof; how to take further action to play vital effect to electric motor protective device, this relates to the problems such as the serviceable life of safety in production and equipment.But existing motor status recognition device, adopt technical scheme relative complex, equipment cost is higher, and function is also few.
