Energy Monitoring system


Energy Monitoring system


Energy monitoring system for heating process of the quenching machine tool through the comparative analysis of various parameters, schedule data or curve of standard, set up the qualified lower limit on workpiece, can store a lot of process and history data of process, to facilitate later call and processing quality of the product traceability, might be used for remote monitoring parameters, can implement parameters to print.

Basic function: it can compare the user’s stored curve with the actual curve for analysis, and display the instantaneous power, voltage, current value and heating time of the power supply through the curve and data; The upper and lower limits of power output can be set, with overlimit alarm function, such as “underburning” and “overburning”.

Workpiece management function: The workpiece library can store tens of thousands of workpiece processing parameters, used to record and save the workpiece model, induction heating power output voltage, current, power, heating time, etc., and can set the upper limit and lower limit.

Real-time display function of power output power: display the changing trend of voltage, current and power of induction heating power during heating process by curve.

Curve and data storage function: the user in the process of debugging, will be one of the workpieces records completely conform to the requirements of the energy curve, and the heating power output in the process of quenching parameters such as voltage, current, power and data saved to the corresponding files, for later review and analysis, or as a standard file.

This set of quality control system uses database system to store relevant data in quenching production. The database system records data stably and reliably, which can realize fast storage and query. The system provides the query function, according to the operator’s name, production date, workpiece model, workpiece number and other key items to query the relevant production data records, easy to use. The system also has data backup function to prevent data loss. The use of energy monitoring system can improve the quality of quenching products, ensure the reliable execution of quenching process, and the use of data recording and storage function is conducive to process analysis, improvement, is an indispensable helper of quenching production.

The quality control system includes energy acquisition system, temperature and flow monitoring system, RSS422 communication circuit and so on. Each signal acquisition system is the basis of the monitoring system, RSS422 communication circuit for energy acquisition system and interface monitoring connection, realize data transmission of energy, energy monitoring interface is the core of energy monitoring system, can realize energy data receiving, display, storage, and waveform mapping, etc., its control in the design of the alarm function, The problem of heat treatment of induction heating power supply in quenching process is indicated by alarm.

The principle of the energy acquisition system is to use sensors and detection circuits to detect voltage, current and frequency signals of the induction heating power supply, and then adjust the detected voltage and current signals. Through analog to digital conversion, the collected analog signals are converted into digital signals and provided to MCU for processing. After conditioning, the frequency signal is directly transmitted to MCU for counting. After signal processing, MCU transmits these data to industrial computer through RSS422 communication circuit.

The interface of the energy monitoring system can display the data collected by the data acquisition system on the industrial computer, which is convenient for users to monitor the heating state of the induction heating power supply in real time. The energy monitoring system interface includes the user login interface, main monitoring interface, historical data query interface, and parameter setting interface. The core of the interface is the main monitoring interface, which can complete data reception, data signal processing and display, voltage, current and frequency abnormal alarm, voltage, current and frequency history numerical call, voltage, current and frequency waveform drawing and program exit, etc
