Accompanying drawing explanation
Fig. 1 is the circuit structure block diagram of the utility model embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
As shown in Figure 1: a kind of interactive PLC training platform, comprises PLC, touch-screen, analog quantity spread module, pushbutton unit, switch element, indicator unit, temperature sensor, carbon dioxide sensor, pressure transducer, current sensor, frequency converter and motor.The input end of PLC is electrically connected with analog quantity spread module, pushbutton unit, switch element, and the output terminal of PLC is electrically connected with touch-screen, indicator unit; The input end of analog quantity spread module is electrically connected with temperature sensor, carbon dioxide sensor, pressure transducer, current sensor, and the output terminal of analog quantity spread module is electrically connected with frequency converter, and frequency converter is connected with motor.
In the present embodiment, PLC is used for obtaining from the interface of temperature sensor, carbon dioxide sensor, pressure transducer, current sensor, pushbutton unit and switch element and storing data and control frequency converter and indicator unit action;
Touch-screen is used for carrying out optimum configurations and display teaching teaching, monitoring of tools and simulative debugging function; Pushbutton unit, switches for action control, function, by User Defined, as controlled motor start and stop by pressing or press out button, within several seconds, realizes the function switching etc. of practical training project by long touching the button; Switch element, switch for action control, function, by User Defined, its functional equivalent, in pushbutton unit, is just switched by the different gears of switch; Indicator unit, for state instruction, by User Defined, represent as pilot lamp is bright in motor operation, pilot lamp flicker represents operating mistake; Button, switch and pilot lamp can be multiple.
Analog quantity spread module, delivers to PLC comprehensive improvement for the simulating signal collected being concentrated after treatment.Analog quantity spread module in the present embodiment is EM235 module, EM235 module has 4 road analog inputs and 1 road analog output, the collection of temperature sensor, carbon dioxide sensor, pressure transducer, current sensor 4 kinds of analog signalses can be completed, and export the operation of 1 road Analog control frequency converter and motor, regulate the rotating speed of motor.Wherein, temperature sensor is used for measuring indoor temperature in real time; Carbon dioxide sensor is used for the gas concentration lwevel in sensing chamber; Pressure transducer is for measuring the finger pressure of student; Current sensor is used for the electric current of electric power plug socket in sensing chamber, and PLC will obtain and the current value of the temperature value stored, gas concentration lwevel, finger pressure value and electric power plug socket shows on touch-screen.In the present embodiment, the model of temperature sensor is DS18B20, and the model of carbon dioxide sensor is MH-Z12.(module provides by EM235 module data instructions with the concrete pin that is connected of each device, belongs to existing scheme, does not repeat them here.）
The present embodiment measures indoor temperature, air quality and power load by adopting multiple sensor, and utilize touch-screen to carry out experimental project management and supervision, also interesting practical training project can be carried out, as carried out the match of student's finger pressure, thus reach the interactive real training object gathered multi-function in integral whole, help Students ' Learning to grasp PLC control system dramatically.
