Description of drawings
Fig. 1 is frame assumption diagram of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of non-burning brick water tester of the present utility model, comprise moisture content signal amplification circuit 1 and single chip machine controlling circuit 2, the output signal of described moisture content signal amplification circuit 1 is transferred to A/D data converting circuit 11, the output signal of described A/D data converting circuit 11 is sent to single chip machine controlling circuit 2, and the output signal of described single chip machine controlling circuit 2 sends to RS485 communication interface circuit 21 and warning circuit 22.
Described moisture content signal amplification circuit 1 is made of sheet metal A, B end and operational amplification circuit IC2, described sheet metal A, B install and are inserted on the non-burning brick surface, the output terminal of sheet metal A connects power supply, connect resistance R 3 dividing potential drop over the ground by supply voltage, the output terminal of sheet metal B is connected to operational amplification circuit IC2, described operational amplification circuit IC2 connects resistance R 1 dividing potential drop over the ground, and being connected to A/D data converting circuit IC3 by the output terminal of operational amplification circuit IC2, A/D data converting circuit IC3 sends data to 2051 single-chip microcomputer IC1.
As sheet metal A, B installs and is inserted on the non-burning brick surface, by supply voltage through R3 dividing potential drop over the ground, by the on-insulated body of non-burning brick surperficial moisture content, when if moisture content is strong, sheet metal A, produce weak voltage between the B, output signal after the inner amplification of operational amplification circuit IC2, be input to A/D data converting circuit IC3 the 2nd pin, by the 5th of A/D data converting circuit IC3,6, the 11st of 7 pin and 2051 single-chip microcomputer IC1,18,19 pin are formed data A/D data converting circuit 11, read various data-signals by 2051 single-chip microcomputer IC1, after the identification of 2051 single-chip microcomputer IC1 internal processes is judged, connect to form RS485 communication interface circuit 21 by 75176 interfaces driving chip IC 4 and 2051 single-chip microcomputer IC1, drive chip IC 4 by 2051 single-chip microcomputer IC1 to 75176 interfaces and send the driving command signal, after 75176 interfaces drive the decoding of chip IC 4 internal circuits, reach computerized control system through the RS485 system bus, system software shows current moisture content data message; Another road output makes news Chinese percussion instrument BD send prompting sound by the 14th pin output low level of 2051 single-chip microcomputer IC1, illustrates that non-burning brick moisture content is relatively more sufficient, for maintenance technology provides scientific basis.
Above-described only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
