Intelligent motor management unit of chest of drawers

Abstract

The invention relates to an intelligent motor management unit of a chest of drawers. The unit comprises a main body module (1) and a measurement module (2), wherein the main body module (1) comprises a CPU unit I (1.1), a button processing circuit (1.2), a switching value input processing circuit (1.3), a PTC / NTC (Positive Temperature Coefficient / Negative Temperature Coefficient) input processing circuit (1.4), a data storage circuit (1.5), a clock circuit (1.6), a communication circuit I (1.7), a 485 circuit (1.8), a relay output circuit (1.9), an LED control circuit (1.10), an extension module interface circuit (1.11) and a measurement module interface circuit (1.12), wherein the measurement module (2) is connected with the measurement module interface circuit (1.12) of the main body module (1). The intelligent motor management unit of the chest of drawers has the advantages of easy use, easy installation, easy replacement and easy upgrading, and the use cost is further reduced.

Description

(1) Technical field [0001] The invention relates to an intelligent motor protector / motor management unit, in particular to a 1 / 4 drawer cabinet intelligent motor management unit. (2) Background technology [0002] Where electric motors are used, electronic motor protectors have been widely used. The feedback from the market shows that many functions (such as transmission, measurement, display, communication, control, protection) are integrated into the motor protector, which can save a lot of installation space on site, reduce on-site product types, reduce construction workload, and shorten Project cycle and cost saving. [0003] At present, the conventional electronic motor protectors on the market more or less integrate the above functions. The integration method is: use a shell to integrate many functions. This causes many conventional electronic motor protectors to be incomplete in size. Applicable to 1 / 4 drawer cabinets (or other power distribution cabinets, motor management...

AI Technical Summary

Problems solved by technology

[0003] At present, conventional electronic motor protectors on the market more or less integrate the above-mentioned functions. Applicable to 1 / 4 drawer cabinets (or other power distribution cabinets, motor management centers); if the system / function needs to be upgraded on site, the original product can only be dismantled and then expanded or returned to the factory for replacement, and production will be interrupted; if a function The module is damaged, and the entire device needs to be dismantled, repaired or replaced; product applicability, reliability, and replaceability are not high, which increases user costs
