Detailed Description
Example one
Referring to fig. 1, the novel intelligent control system of the embodiment includes a monitoring system, a variable transformer, a control voltage module, a contactor, a motor, and a 380V power supply, wherein a first pressure sensor is arranged at the 380V power supply, and transmits an output voltage signal at the 380V power supply to the monitoring system (see fig. 1 for feedback signal at 1) for detecting whether the 380V power supply is stable; the contactor is provided with a third pressure sensor, and the third pressure sensor transmits a voltage signal at the contactor to a monitoring system (see a feedback signal at a feedback 3 position in fig. 1) for detecting whether the contactor is normally opened or closed; a second pressure sensor is arranged at the motor, and transmits a voltage signal at the motor to a monitoring system (see a feedback signal at a feedback 2 position in fig. 1) for detecting whether the motor operates normally; the control voltage module feeds back a voltage signal at the position of the variable transformer to the monitoring system (see a feedback signal at a position of feedback 4 in figure 1), and the monitoring system controls the on-off of the contactor through the variable transformer and the control voltage module so as to control the operation of the motor. The variable transformer can receive external information change and output a stable voltage source; the monitoring system can independently detect the changes of input voltage, output voltage, load voltage and current and output related information to the variable transformer; the variable transformer outputs a regulated voltage to the contactor and feeds back to the monitoring system.
The control method of the novel intelligent control system comprises the following steps:
(1) monitoring a preset voltage value of the system;
(2) the monitoring system monitors the voltage at the 380V power supply, the voltage at the motor and the voltage at the contactor in real time through a first pressure sensor, a second pressure sensor and a third pressure sensor respectively;
(3) comparing the 380V power supply voltage, the motor voltage and the contactor voltage in the step (2) with the preset voltage value by the monitoring system; when the comparison result is abnormal, the monitoring system controls the output of the variable transformer to be 0 through an algorithm so as to disconnect the contactor, thereby controlling the starting and stopping of the motor and protecting equipment.
