Abstract
The utility model relates to a measuring and control device for hydraulic oil level of a brick machine. The measuring and control device comprises a thermistor liquid level collection module, a comparator module, a microprocessor control module, a solenoid valve drive module and an LED display module. Output signals of the thermistor liquid level collection module are controlled and output via the comparator module to the microprocessor control module, the solenoid valve drive module and the LED display module. Output signals of the microprocessor control module are sent to a PLC control module through an RS485 communication interface module. Two thermistors are employed to measure level conditions of non-conducting liquid. The measuring and control device is also provided with an apparatus with LED display and automatic control liquid injection equipment, and is networking with a brick machine control system for monitoring through an RS485 system bus after processing is conducted by a single-chip microcomputer. The measuring and control device has the characteristics of novel structure, simple principle, reliable performance, etc.
Description
Technical field
The utility model relates to a kind of pick-up unit, particularly be a kind of brick machine hydraulic pressure oil level measure and control device.
Background technology
The corollary apparatus oil pump station of brick machine is most important, and the height of its hydraulic oil liquid level is directly connected to the quality of brickmaking, so monitors oil pumping plant internal hydraulic pressure oil level in real time can be realized brick machine systematization monitoring.
The utility model content
The purpose of the utility model is to provide a kind of brick machine hydraulic pressure oil level measure and control device.
The utility model solves the technical scheme that its technical matters adopted: a kind of brick machine hydraulic pressure oil level measure and control device; Comprise thermistor liquid level acquisition module, comparator module, microprocessor control module, solenoid-driven module and LED display module; The output signal of said thermistor liquid level acquisition module is through comparator module control transmission to microprocessor control module, solenoid-driven module and LED display module, and the output signal of said microprocessor control module sends to the PLC control module through the RS485 communication interface modules.
Further, said thermistor liquid level acquisition module is fixed on two identical thermistors need surveying the upper limit place of liquid level and gathers liquid level signals by being close to.
Further, the COM input port of said RS485 communication interface modules is connected with the SN75176 communication interface modules.
Through adopting above-mentioned technical scheme; The beneficial effect of the utility model is: the utility model adopts the level condition of two non-conductive liquid of thermosensitive resistance measurement; And have after LED shows, controls automatically the device of liquid-injection equipment, handled by single-chip microcomputer; Realize and brick machine control system networking monitoring having characteristics such as novel structure, principle are simple, dependable performance through the RS485 system bus.
Description of drawings
Fig. 1 is the circuit theory diagrams of the utility model;
Fig. 2 is the circuit diagram of the utility model.
Embodiment
Like Fig. 1, shown in Figure 2; The brick machine hydraulic pressure oil level measure and control device of the utility model; Comprise thermistor liquid level acquisition module 1, comparator module 2, microprocessor control module 21, solenoid-driven module 22 and LED display module 23; Said thermistor liquid level acquisition module 1 is fixed on two the identical thermistor R1 and the Rt1 that need to survey the upper limit place of liquid level and gathers liquid level signal by being close to, and reduces the influence of environment temperature to both intrinsic standoff ratios like this.The output signal of thermistor liquid level acquisition module 1 is through comparator module 2 control transmission to microprocessor control module 21, solenoid-driven module 22 and LED display module 23; The output signal of said microprocessor control module 21 sends to PLC control module 212 through RS485 communication interface modules 211, and the COM input port of said RS485 communication interface modules 211 is connected with SN75176 communication interface modules IC3.
When hydraulic oil in brick machine oil pumping plant is annotated the tapping body, when also not reaching thermistor R1 and Rt1,, thermistor R1 heating rises because of making thermistor Rt1 temperature; And resistance reduces, and makes comparer IC2 the 2nd, 6 pin voltages be lower than 2V, and then comparer IC2 internal comparator is just overturn; The 3rd pin output high level of comparer IC2, light emitting diode LED is not luminous, the relay J adhesive; Normally opened contact JK1 is closed, makes the solenoid valve energized, continues to the inner liquid that injects of oil pump station; When liquid was filled it up with, thermistor R1, Rt1 temperature descended, and its resistance rises; Make comparer IC2 the 2nd, 6 pin voltages be raised to 4V, then the upset of comparer IC2 internal comparator resets its 3rd pin output low level; Be input to the 36th pin I/O end through resistance R 3 current limlitings, this signal, be low level state, by its 36th port status of microprocessor IC1 scanning into processor IC1; Form RS485 communication interface modules 211 by the 1st, 2,3,4 ends of resistance R 4, SN75176 communication interface modules IC3 and the 10th, 11,25 ends of microprocessor IC1; Send the warning message data through SN75176 communication interface modules IC3 to brick machine PLC control module 212, show current oil pump oil level state, realize and the PLC networking monitoring by PLC.Because the 3rd pin output low level of comparer IC2 makes the luminous warning of LED, normally opened contact JK1 breaks off simultaneously, and solenoid valve loses voltage and cuts out, and equipment no longer injects liquid in oil pump station.
An above-described preferred embodiment that is merely the utility model can not limit the scope that the utility model is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
