Abstract
The utility model relates to a monitoring circuit for hydraulic oil of a building block machine and the monitoring circuit comprises a temperature-sensitive circuit and a single-chip microcomputer control circuit. Output signals of the temperature-sensitive circuit are transmitted to the single-chip microcomputer control circuit by a comparator circuit. Output signal control of the single-chip microcomputer control circuit is transmitted to an RS485 communication interface circuit. When an abnormal hydraulic oil temperature is determined by the single-chip microcomputer control circuit, the abnormal hydraulic oil temperature is transmitted to a PLC operation controller by an alarm bus, thereby realizing networking monitoring, protecting the building block machine device and raising qualified rate of brick-manufactured finished products.

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 block building machine hydraulic oil observation circuit of the present utility model, comprise temperature-sensitive circuit 1 and single chip machine controlling circuit 2, the output signal of described temperature-sensitive circuit 1 transfers to single chip machine controlling circuit 2 through comparator circuit 11, and the output signal control of described single chip machine controlling circuit 2 is sent to RS485 communication interface circuit 21.
Described temperature-sensitive circuit 1 adopts the temperature-sensitive diode QL collecting temperature signal that is installed in the hydraulic reservoir, described temperature-sensitive diode QL is in parallel with resistance R 1, resistance R 1 and adjustable potentiometer W1 dividing potential drop, described comparator circuit 11 is made of the capacitor C 2 that 555 time base circuit IC1 and output terminal thereof connect, the fuel tank hydraulic oil temperature is when normal value, resistance R 1 and potentiometer W1 dividing potential drop, so that the 6th pin current potential of 555 time base circuit IC1 is lower than 1/3VDD, the 3rd pin output high level signal of 555 time base circuit IC1, this signal is input to the 35th end of single-chip microcomputer IC2 through resistance R 2, after single-chip microcomputer IC2 internal program is judged, do not send control signal.
When the fuel tank hydraulic oil temperature is higher than the set temperature value, the resistance of temperature-sensitive diode QL diminishes, thereby so that the current potential of the 6th pin of 555 time base circuit IC1 is higher than 2/3VDD, the 3rd pin of 555 time base circuit IC1 changes low level into, this signal is input to the 35th end of single-chip microcomputer IC2 through resistance R 2, after single-chip microcomputer IC2 internal program is judged, by the 25th of single-chip microcomputer IC2,10, the 1st of 11 ends and SN75176 communication interface chip IC3,2,3,4 ends connect to form RS485 communication interface circuit 21, IC2 sends data-signal by single-chip microcomputer, after SN75176 communication interface chip IC3 decoding conversion, pass to the PLC controller, after PLC decoding, send the driving instruction, hydraulic control system is stopped, avoiding because of the too high damage equipment of hydraulic oil.
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.
