Accompanying drawing explanation
Fig. 1 is a kind of object moving direction identification circuit schematic diagram.
In figure: 1-baffle plate, J1-relay, J2-relay, A-output port, B-output port.
Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1, a kind of object moving direction identification circuit, comprise baffle plate 1, light source L1, light source L2, direct supply E0, battery power E1, battery power E2, resistance R1, resistance R2, resistance R3, photoresistance RS1, photoresistance RS1, potentiometer RW, diode D1, diode D2, diode D3, diode D4, triode T1, triode T2, triode T3, triode T4, relay J 1 and relay J 2, described baffle plate 1 there are two apertures, light source L1, light source L2 is irradiated to photoresistance RS1 respectively by two apertures, on photoresistance RS2, described photoresistance RS1, photoresistance RS2, resistance R1 and resistance R2 connects, the resistance R1 other end connects potentiometer RW side pin and is connected with output port A, the resistance R2 other end connects potentiometer RW opposite side pin and is connected with output port B, potentiometer RW middle pin is connected with 4V direct supply E0 positive pole, with photoresistance RS1 while of direct supply E0 negative pole, photoresistance RS2 connects, described diode D1 is in parallel with relay J 1, diode D1 positive pole is connected with 12V battery power E1 positive pole, with triode T1 collector while of diode D1 negative pole, triode T2 collector connects, triode T2 base stage is connected with triode T1 emitter, triode T2 emitter is connected with diode D2 negative pole, described resistance R3 is connected with input port A, with triode T1 base stage while of the resistance R3 other end, triode T3 base stage connects, with triode T4 collector while of triode T3 collector, diode D3 positive pole connects, triode T3 emitter is connected with triode T4 base stage, triode T4 emitter is connected with diode D4 positive pole, diode D3 is in parallel with relay J 2, diode D3 negative pole is connected with 12V battery power E2 positive pole, with diode D4 negative pole while of battery power E2 negative pole, diode D2 positive pole, battery power E1 negative pole, output port B connects and ground connection.
Principle of work of the present utility model is: photoresistance RS1, photoresistance RS2 that two characteristics are consistent are arranged on the same side in object of which movement path, spaced suitable distance.Opposite side relative position installs light source L1, light source L2 respectively, makes object rectilinear motion between light source and photoresistance.Adopt circuit as shown in the figure can judgment object direction of motion.Circuit is made up of electric bridge and polarity discriminating two parts.Photoresistance RS1, photoresistance RS2, resistance R1, resistance R2 and potentiometer RW form electric bridge, are powered by 4V direct supply E0, and output port A, output port B export.Make photoresistance RS1 and photoresistance RS2 shading simultaneously or illumination before measurement, regulator potentiometer RW, makes bridge balance.UAB=0V。During measurement, when object moves from bottom to top, first photoresistance RS2 is blocked, resistance increases, photoresistance RS1 is by illumination, and resistance is less, and electric bridge is unbalance, UA>UB, UAB>0V, then triode T1, triode T2 end, triode T3, triode T4 conducting, relay J 1 remains open state, relay J 2 adhesive.When object continues to move upward to photoresistance RSl position, situation is contrary, and relay J 1 adhesive, relay J 2 is opened.If object moves from top to bottom, then contrary with above-mentioned situation, the first adhesive of relay J 1, adhesive after relay J 2.Therefore, can the direction of motion of judgment object according to the sequencing of relay J 1 and relay J 2 adhesive, and give corresponding switch controlling signal and export.By in addition perfect for the switching signal exported, directly result can also be provided to object moving direction.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
