Brick machine mixing plant control device

Technical field

The utility model relates to a kind of control device, particularly be a kind of brick machine mixing plant control device.

Background technology

Brick machine mixing plant is the raw-material main making apparatus of brick machine, is concerning the quality of brickmaking, if mixing plant will cause paddle to damage because of the raw material particle is excessive.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of brick machine mixing plant control device is provided.

The technical scheme that its technical problem that solves the utility model adopts is: brick machine mixing plant control device, comprise infrared correlation testing circuit, single chip machine controlling circuit, power driving circuit and wireless receiving and dispatching circuit, the output signal of described infrared correlation testing circuit sends to single chip machine controlling circuit, export power driving circuit and wireless receiving and dispatching circuit to by single chip machine controlling circuit control, described single chip machine controlling circuit also connects a watchdog circuit.

Described infrared correlation testing circuit by infrared light-emitting diode VD1 series resistance R1 after, the series circuit of the series circuit of parallel with infrared line reception diode VD2 and resistance R 2 and resistor W and capacitor C2 constitutes again.

Described infrared light-emitting diode VD1 and infrared receiver diode VD2 are installed on the agitator wire side upper and lower side of mixer respectively, and the infrared ray that infrared light-emitting diode VD1 is sent just in time is radiated in the hole of wire side.

The specific embodiment

As shown in Figure 1 and Figure 2, brick machine mixing plant control device of the present utility model, comprise infrared correlation testing circuit 1, single chip machine controlling circuit 2, power driving circuit 3 and wireless receiving and dispatching circuit 4, the output signal of described infrared correlation testing circuit 1 sends to single chip machine controlling circuit 2, export power driving circuit 3 and wireless receiving and dispatching circuit 4 to by single chip machine controlling circuit 2 controls, described single chip machine controlling circuit 2 also connects a watchdog circuit 5.

Described infrared correlation testing circuit 1 by infrared light-emitting diode VD1 series resistance R1 after, the series circuit of the series circuit of parallel with infrared line reception diode VD2 and resistance R 2 and resistor W and capacitor C 2 constitutes again, described infrared light-emitting diode VD1 and infrared receiver diode VD2 are installed on the agitator wire side upper and lower side of mixer respectively, the infrared ray that infrared light-emitting diode VD1 is sent just in time is radiated in the hole of wire side, thereby the infrared ray that makes infrared light-emitting diode VD1 send is not radiated on the infrared receiver diode VD2 all the time, like this, the M1 point voltage can be a low level state all the time just, illustrates that the raw material particle diameter is in normal value.

When the raw material particle diameter exceeds standard, infrared light is blocked by the particle object, infrared receiver diode VD2 receives the infrared ray of infrared light-emitting diode VD1, make the negative pole M1 point of infrared light-emitting diode VD1 produce a series of continuous negative pulses that do not produce, and be coupled to the positive pole of capacitor C2 by capacitor C1, thereby capacitor C2 is filled with, the M1 point voltage is approximately 3V, be in high level state, this signal is input to the 38th pin I/O port of single-chip microcomputer IC1, at this moment, divide two-way output through single-chip microcomputer IC1 internal processes control signal, first via output drives signal by the high level of the 7th pin output of single-chip microcomputer IC1, makes triode VT2 conducting, relay J adhesive through resistance R 5, its electric shock J-1 transfers normally closed point to by often opening, make motor contactor M dead electricity, turn-off the stirring motor power supply, thus the safety of protection equipment; The second tunnel output makes triode VT1 conducting by the high potential driving signal of the 26th pin I/O mouth output of single-chip microcomputer IC1 through resistance R 3, be input to the 2nd pin of FDD-5 transmitter module IC4, and deliver to its 3rd pin CP modulation signal input end, high-frequency signal to emission is modulated, antenna TX promptly launches modulated frequency electromagnetic waves to JDD-5 receiver module IC3, the 4th pin CPA audio signal output end of JDD-5 receiver module IC3 directly drives common electrical dynamic formula loudspeaker Y and sends chimes of doom, its the 2nd pin data output end output high level makes LED 1 get electroluminescence simultaneously, expression receives the alarm signal of extension set, and notice is controlled personnel to troubleshooting of faults.

The 1st, 7,8 pin that connect watchdog chip IC2 by the 9th, 17, the 16 pin outputs of single-chip microcomputer IC1, form reset circuit by resistance R 6, capacitor C5, the 9th pin of single-chip microcomputer IC1 and the 7th pin of watchdog chip IC2 are resetted, prevent that single-chip microcomputer IC1 internal processes is in the endless loop state.

Above-described only is a preferred embodiment of the present utility model, can not limit the scope that this practicality 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.
