Abstract

The invention discloses a measurement and control integrated motor, which comprises a motor and a measurement and control device, wherein the measurement and control device comprises a shell, a frequency converter, a power supply wiring terminal, a data processing unit and a signal wiring terminal. The invention also discloses a measurement and control integrated motor cluster measurement and control system, which comprises a plurality of measurement and control integrated motors, a signal acquisition subsystem, a signal and power transmission subsystem, a signal processing subsystem and a control and maintenance subsystem. The invention also discloses a measurement and control integrated motor cluster measurement and control method, which comprises steps: a sensor detects motor operationinformation and the information is transmitted to the data processing unit; the data processing unit transmits information acquired by the sensor to the signal processing subsystem; the signal processing subsystem processes the received information; the control and maintenance subsystem controls the motor according to the processing result of the signal processing subsystem and judges whether alarm is needed or not, if yes, a state alarm module is controlled to give an alarm, and if not, no alarm is given.

Description

technical field [0001] The invention relates to the field of motors, in particular to a measurement-control integrated motor, a cluster measurement and control system and a cluster control method. Background technique [0002] Motors are widely used in various work scenarios such as warehousing and logistics, port machinery, and automated production lines. Such work scenarios require multiple motors to be distributed in clusters at the work site, and the system-level transmission function is realized by controlling the linkage of multiple motors. During the operation of the motor cluster, each motor faces different working conditions and health states, and motion control for starting, stopping, accelerating or decelerating is required, and maintenance is performed according to the health states of different motors. [0003] At present, for the control problem of geared motor clusters, the scheme of distributed control unit is generally adopted at the geared motor work site. ...

AI Technical Summary

Problems solved by technology

At present, there are the following problems in the distributed control and monitoring of geared motor equipment clusters: (1) The existing control system and state monitoring system belong to two systems, which causes redundancy of hardware devices with similar functions in terms of hardware, and multi-type signals It is easy to form mutual interference in the industrial site; (2) The power cables, control signal cables and status monitoring signal cables used in the cluster-distributed geared motor equipment form loops respectively, resulting in problems such as excessive cables and heavy wiring workload. It is easy to cause operational errors of on-site installation and commissioning personnel, and there are many hidden trouble points; (3) The separation of the control system and the monitoring system results in the cost of power cables, control signal cables and status monitoring signal wireless transmission devices used in geared motor equipment clusters and wiring man-hour cost waste
