Belt force control and monitoring interface design

1 power control features
Power control is currently the more popular generic configuration software, it has a better graphical interface features, you can easily construct their own data acquisition system. Its database point easily with data acquisition card PCL-818L data link channel with receive data, send data

Function, but also has to generate real-time curve, historical curve, statements and report printing, alarm and other functions, in addition, the configuration screen can truly reflect real-time status.
2 Monitoring Interface Design
After monitoring hardware design interface design, power control database point PCL-818L data channel link. The detection device provides the brightest voltage and current signals from the PCL-818L data acquisition card is converted to binary integer registers stored on the card, the power control  Belt conveyor

Read from the data, subject to scale conversion, to restore the real value of each signal.
(1) Deviation Status: Each bit numbers deviation switch state is divided into normal, an alarm and two alarm three states. Each deviation switch is divided into left and right deviation alarm deviation alarm. When the belt is normal, the lights are green; when an alarm occurs, the alarm light is yellow

Color; when two alarms, the alarm indicator is red.
(2) Belt speed: the speed of the current value with a real-time display and over-under speed indicator composed of two parts. Over under the light from the high speed limit, high limit, low limit and low limit four indicator lights. When the belt speed is normal, all lights are green; when the tape speed exceeds the high limit setpoint and less than high

Limit setting, high limit indicator is red, others are green; when the tape speed exceeds the high limit setting, high limit indicator is red, others are green; when the belt slip, belt speed low the value set at the lower limit set above the low limit value, the lower limit light is red, the

Which are green; when the belt breaks while tape speed is lower than low limit set value, the low-low limit indicator is red, others are green. belt conveyor design
(3) Temperature: including real time display of the current value of the temperature and lights in two parts. Light from the high and high limit two indicator lights. When the temperature is normal, the two lights are green; when the temperature exceeds the high limit setpoint high limit but below the set value, high limit light is red

, High limit indicator is green; when the temperature exceeds the high limit setting, high limit indicator is red, high limit indicator is green.
(4) Throughput: Includes throughput real-time display and the current value of the indicator in two parts. Light from the high and high limit two indicator lights. When throughput is normal, two lights are green; when throughput exceeds the high limit setpoint high limit but below the set value, high limit indication

Light is red, high limit indicator is green; when throughput exceeds the high limit setting, high limit indicator is red, high limit indicator is green.
(5) cumulative weight: real-time display of the cumulative weight of the current material.
(6) Parameter settings: on the belt conveyor operating limit parameters.
(7) Real-time curve: Real-time curve is a belt speed, throughput, temperature and time values ??were plotted versus time and the variables - time profile. View real-time curve conveyor speed, throughput and temperature state at the present time, but also real-time curve

Data can be stored for a short time trend, so it can be used to understand the current operational status of equipment. Real-time curve can automatically scroll, you can quickly reflect the variables change over time. Including real-time curve trend curve conveyor speed, throughput, trend curves and temperature

The trend curves.
(8) historical curve: the curve of history is preserved in the historical data in real-time database changes over historical time, a two-dimensional graph plotted. History curve can also auto-scroll to the X-axis is the time axis, Y-axis is variable axes. Through history curves can view past a certain time period conveyor

Speed, throughput and temperature trend curves. History curve includes conveyor speed curve of history, throughput, and the temperature history of the historical curve curve.
(9) History Report: historical reports provide a viewing and printing historical data and statistics tool. For historical reports can be manual and automatic printing. Historical reports from the database according to a certain sampling methods to obtain one or more points of historical data in tabular form display

Displayed. Historical statements can query a certain time period conveyor belt running speed, throughput, temperature, total weight, etc. running parameters.
(10) Alarm Record: When an exception occurs belt running through the alarm to notify the operator control process and system situation. When the belt speed, throughput, temperature gauge, or too fast, slippery, deviation or other abnormal condition occurs, the alarm window display and record the more limited

Time, variable names, the alarm level, the current value and the limit value. When a new alarm occurs, the alarm automatically scrolls the window, the window always shows the last occurrence of the alarm.
