Finish the interface design, the definition of animation connection and the implementation of control algorithm in the screen development system of kingview. In this system, the upper configuration king contains the main interface system, boot screen window. We can click the control to close the circuit breaker and ac contactor, and at the same time increase or decrease the frequency of the converter to realize remote control. The configuration screen also provides real-time feedback on frequency, output voltage, circuit breaker and ac contactor.

    The structure of the experimental device, including frequency converter, industrial control machine, motor, circuit breaker, ac contactor, etc. At the same time, in the diagram can also clear in the indoor temperature, frequency converter, inverter voltage, ac contactor closing or opening state, power supply circuit breaker closing or opening state or state information such as real-time data.

    5 Conclusion

    Using a ADAM5000 series experimental device, a distributed monitoring system based on configuration king is designed and developed. Real-time data collection at room temperature is realized. The on-off state of the circuit breaker and contactor can be monitored in real time through the on-off control of the upper computer. When the control circuit breaker and contactor are closed, the frequency converter is energized, and the output frequency of the converter can be controlled by clicking the mouse, so as to control the motor speed. The distributed monitoring system has certain practicability and universality and can be extended to other monitoring systems in industrial production process.
