Abstract

The invention discloses a modularized microcomputer motor protective monitoring device. The device comprises a basic module, a communication module, a display module, a power module, an analog quantity input / output module, a state quantity input / output module and internal CAN bus. The device is characterized in that: the basic module comprises a minimum requirement system, is provided with a protection function, a measurement function and a management function, and can be independently operated to meet the requirement of low-end users; and the communication module, the display module, the power module, the analog quantity input / output module and the state quantity input / output module can be selected to meet the requirement of different users on different working conditions. The five modules except for the basic module can be increased or reduced at any time according to the user requirement; each module can perform independent test and is communicated with the basic module by adopting the CAN bus; and after being combined, the whole device can be used once the device is powered on, so that the aim of updating the system fast and safely or increasing functions for the device is fulfilled.

Description

1. Technical field [0001] The invention relates to the technical field of microcomputer motor protection and monitoring, in particular to the technical field of microcomputer low-voltage motor protection and monitoring modularization. 2. Background technology [0002] At present, the general microcomputer motor protector monitoring device is integrated or the display is separated from the main body. It is required to determine the detailed model and functional technical requirements in the system design stage. After the device has been installed and debugged, or the system is upgraded after a period of use , If you want to increase equipment functions, especially hardware functions, you often need to dismantle and replace the entire device. The installation and re-commissioning cycle is too long, which affects normal production and brings many unpredictable insecurities to the system. 3. Contents of the invention [0003] The purpose of the present invention is to design a...
