Accompanying drawing explanation
Fig. 1 is the theory diagram of the concealed wire detector in the embodiment of the present invention;
Fig. 2-a is that in concealed wire testing process, array of temperature sensor vertical direction moves schematic diagram;
Fig. 2-b is that in concealed wire testing process, array of temperature sensor horizontal direction moves schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
As shown in Figure 1, the concealed wire detector that the present invention is based on temperature effect comprises single-chip microcomputer, array of temperature sensor, acoustic-optic alarm and supply module, the output terminal of array of temperature sensor is connected with the input end of single-chip microcomputer, to detect body of wall temperature variation, the output terminal control linkage acoustic-optic alarm of single-chip microcomputer, the power supply port of supply module is connected with the power port of single-chip microcomputer, for providing power supply for single-chip microcomputer.In order to know the size of temperature in real time in testing process, the output terminal of single-chip microcomputer is also connected with light-emitting diode display.
In the present embodiment, single-chip microcomputer can select the single-chip microcomputer of 51 series as 89C51, for collection, temperature sensor array signal, judge temperature variation, in the middle of array, the sensor temperature difference is greater than setting value, control acoustic-optic alarm is reported to the police, the temperature that sensor each in array of temperature sensor detects will be shown at light-emitting diode display, supply module provides power supply for whole detection system simultaneously.
In the present embodiment, array of temperature sensor selects 3 temperature sensors of high precision DS1624 compositions, and its measurement resolution is 0.03 DEG C, and measurement range is-55 ~+125 DEG C.The array of temperature sensor sketch of this patent is shown in that (3 "○" represent 3 temperature sensors 1 to Fig. 2-a and Fig. 2-b, the thick straight line of black 2 represents concealed wire to be detected), because concealed wire 2 to be detected produces low-grade fever in galvanization, utilize temperature sensors of high precision array detection to body of wall temperature variation, 3 temperature sensors are different from concealed wire distance, its temperature detection value is different, all can be presented on light-emitting diode display.
Because concealed wire mostly is smooth vertical and horizontal mode, when assumed temperature sensor array moves down along body of wall, as shown in Fig. 2-a, three temperature sensors detect that body of wall temperature is identical, then when moving down, three temperature sensing actuator temperatures raise simultaneously, when reach the highest after, temperature declines, and this illustrates that concealed wire is at temperature highest point, and concealed wire is horizontal direction; When assumed temperature sensor array is moved to the left along body of wall, as shown in Fig. 2-b, three temperature sensors detect that body of wall initial temperature is identical, when being moved to the left again, the temperature sensor of low order end detects that temperature is the highest, and take second place in centre, high order end is minimum, illustrate that concealed wire is vertical direction and at the right-hand member of pick-up unit, when continuing to be moved to the left, until intermediate sensor detected temperatures is the highest, the temperature that two side sensers detect is minimum, illustrate that concealed wire is below intermediate sensor, detect and terminate.
