Power supplier is used to each composition electric installation power supply of described metallic solution temperature measurement equipment;
This metallic solution temperature measurement equipment also comprises:
Figure and numeric display unit are used for the conversion of signals of described chromacoder output is become graphic presentation.
The described signal processing apparatus that the utility model has the metallic solution fast temperature measuring equipment at graphic presentation interface comprises:
Computer Processing parts are used for the signal that receives from described chromacoder is carried out various processing;
A digital signal output block that is connected to described Computer Processing parts is used for the result of described Computer Processing parts is exported with the form of digital signal;
A simulating signal output block that is connected to described Computer Processing parts is used for the result of described Computer Processing parts is exported with the form of simulating signal.

The described graphics device that the utility model has a metallic solution fast temperature measuring equipment at graphic presentation interface comprises the pattern display panel on the Computer Processing parts that are connected in the described signal processing apparatus.
The utility model has the metallic solution fast temperature measuring equipment at graphic presentation interface, owing on the basis of the metallic solution thermometric instruments of routine, added the graphic presentation interface, therefore the temperature sensor signal in the measuring process can graphics mode be shown on the display, and all measurement parameters are all set with menu-style.Like this, measuring equipment uses just very convenient, seeks best measurement parameter easily.Saved analysis, calculating like this, determined the loaded down with trivial details program of this measurement result at last, the more important thing is, when measuring failure, can analyze the reason of failure, thereby provide foundation for improving to measure.
Description of drawings:
Reach following detailed description in conjunction with the accompanying drawings, characteristics of the present utility model and benefit will be clearer.Accompanying drawing is:
The circuit block diagram of the metallic solution fast temperature measuring equipment that has the graphic presentation interface that Fig. 1 provides for the utility model;
The circuit diagram of the metallic solution fast temperature measuring equipment that the graphic presentation interface is arranged that Fig. 2 provides for the utility model.
Embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 shows the circuit block diagram that the utility model has the metallic solution fast temperature measuring equipment at graphic presentation interface.As shown in the figure, form by signal pickup assembly 100, chromacoder 200, signal processing apparatus 300 and power supplier 400 by measuring equipment.Temperature signal all is input to analog switch 4 via 1 output of over-voltage over-current protection circuit, the output of cold junction compensation circuit 2, the output of reference voltage generating circuit 3.This analog switch is selected to need the signal of conversion and be entered in the chromacoder 200.In this chromacoder, amplifier and low-pass filter 5 amplify the signal of input and the low-pass filtering shaping; Then, through amplifying and the signal of filtering is input in the A/D converter 6 and converts digital signal to; Then, the digital signal of output is imported 8031 single-chip microcomputers 7, and a road of the digital signal of handling through this single-chip microcomputer 7 outputs to the BCD card 8 that is connected with this single-chip microcomputer 7, thereby measurement result is exported with the form of binary-coded decimal; Another road of the digital signal of handling through this single-chip microcomputer 7 outputs to the D/A converter 9 that is connected with this single-chip microcomputer 7, thereby measurement result is exported with the form of simulating signal.This simulating signal is that size is the current signal of about 4-20 milliampere in the present embodiment.In addition, figure and the numeric display unit 10 that is connected to this single-chip microcomputer 7 can graphic model show measurement result on the display (not shown) of this measuring equipment.This figure and numeric display unit can be VGA graphics devices.So, owing to the graphic presentation that has increased measurement result, measuring process and result can be very clearly observed intuitively, and when measuring failure, failure cause can be sought out targetedly, measure so that improve.And the form that all measurement parameters, measurement result, computing formula all can menus is set and is changed, thereby this follow-on metallic solution temperature measurement equipment can be more efficient, measures more easily, and the control of measurement result is strengthened.In addition, provide operating voltage by power supplier 400 for each component devices in this metallic solution temperature measurement equipment.
