Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structured flowchart of the present utility model.
Embodiment
In order to make technological means of the present utility model, creation characteristic, to reach purpose and effect is easy to understand,, further set forth the utility model below in conjunction with concrete diagram.
As shown in Figure 1, digital measurement control Displaying Meter of the present utility model comprises control module, control module can adopt existing ripe single-chip microcomputer or DSP, it is the core of whole instrument, it is typically provided with storer, and store memory has programmed control and the various mathematical algorithm that will carry out, and control module is carried out calculation process by instruction to input signal, realize the function of whole instrument, and other assemblies of instrument are controlled.
The physical quantity that needs to measure is detected by sensor, according to the needs of measuring, but the sensor adopts pressure sensor in the utility model, temperature sensor, linear transducer etc., the physical quantity that sensor comes out internal measurement is sent to connected control module.Because sensor acquisition is analog quantity, is provided with the A/D modular converter between sensor and the control module, is digital signal input control module again with the analog signal conversion with sensor acquisition.
Existing Displaying Meter, generally be provided with single display module, physical quantity to sensor measurement shows in real time, and the utility model fundamental purpose is in order to solve the deficiency that existing Displaying Meter can only show the physical quantity of current sensor measurement, therefore, in the utility model, control module connects two display modules, and display module then can adopt LED commonly used.In two display modules, first display module is identical with existing Displaying Meter, and the physical quantity of sensor measurement is shown in real time; Second display module then shows current control signal, for example the peak value in control purpose process, setting value etc.Like this, current control signal be can learn in real time, the control and the operation of Displaying Meter helped.
Control signal is made amendment and is realized by the input equipment that is connected with control module, input equipment then can adopt equipment such as keyboard, the keyboard input can be carried out Any Digit to required setting value, peak-data in the test control procedure and set, can drive simultaneously the relay control output module that is connected with control module, finish control function to drive relay according to the actual needs, and the hummer that is connected with control module carries out alarm when meeting the alert if that presets.Simultaneously, instrument is carried out the linear digital verification by keyboard to input sensor signal, can also carry out communication by the RS485 that is connected with control module or RS232 communication interface and slave computer.
