asphalt plant system

asphalt plant(www.asphalt-plant.cn) system is distributed computer control system, which composed by motor operation and status monitoring unit, and controls the amount of overshoot ingredients automatic compensation unit, and the finished material accumulating unit and control unit CARS.Each unit composed by signal acquisition, computing, the implementation of the output and communications and other integral part. control system Interface software using 'MICROSOFT WINDOWS2000' work platform, monitoring screen including craft process display (each motor running status, fault status alarm indication, ingredients parameter display, real-time temperature curve and the trolleys running, etc.), parameter setting screen (the ratio of materials, mixing time parameters and the set of the total mixing), the ratio of access screen, tables (each batch), the cumulative table (daily) query and print screen. All equipment can be achieved in the central control room and remote centralized control, the picture is simple, intuitive, accurate, stable, simple and convenient.

asphalt plant characteristics as follow: 
1.operating system interface Clearly, animation workflow, measurement scales weighing, finished material temperature, the temperature of the heat aggregates, asphalt temperature and the bag inlet temperature and other parameters in real time.
2.Modify the operating parameters in real time online. In the normal course of their work, can be modified the proportion of ingredients, dry mixing, wet mixing and spraying asphalt, finished doors open time, lorry unloading time, bag pulse purge time and other parameters according to the actual needs. 
3.automatic control of aggregate, asphalt batching powder and Automatic compensation of ingredients errors. To ensure the accuracy and stability of gradation.
4.Weight feed sequence can be adjust. The operator can be adjusted weighing hot aggregate order according to actual working conditions. 
5.Recipe storage function. PC can be stored in thousands of matching program ready for use. 
6.Real-time hot aggregate temperature curve. The operator can intuitively grasp the development trends of temperature hot material, easy to control the heat in advance aggregate temperature.
7.Real-time recording data and sound statistics, query and print functions in production. 
8.Sound alarm function. Include motor failure, position detecting faults of stroke switches, silo position high alarm and working process abnormal fault alarm. On the IPC and intuitive touch screen can be demonstrated, and with sound and light alarm. 
9.Self-diagnostic processing. Some fault the system can self-diagnose and take appropriate measures. For example: When the hot aggregate material or put jam called silo door open, the system will automatically open the door buffer door several times, without having to operator manual intervention.
10.Measurement scale calibration can be done directly through the touch screen, simple calibration method, calibration coefficients can be directly EPROM memory. 
11.storage silo fitted on finished material metering device, the operator can keep track of the total amount of the finished material storage silo. 
12.stone and asphalt weighing scales weighing system uses the size of door control. That can guarantee quick fast weighing, but also can ensure the accuracy of the weighing. Can be set via the computer and touch screen doors weighing the amount in advance.
