After the

pins

3 and 4 of the time control switch A3 stop outputting power, the

pins

3 and 4 of the time control switch A2 output power again and enter the two ends of the power input of the relay K, and the power input ends of the positive and negative poles of the motor reducing mechanism M, after the output of the power is stopped by the

pins

3 and 4 of the time control switch A2, when the relay K loses power again, the control power supply input end and the normally closed contact end are closed, the

pins

3 and 4 of the time control switch A3 output power for 8 seconds again and enter the negative and positive pole power supply input end … … of the motor speed reducing mechanism M to circulate continuously, as long as the power supply is not disconnected, under the action of the control circuit, the novel motor speed reducing mechanism capable of circularly controlling M respectively drives the display screen of the multimedia triage screen body 1 to rotate leftwards and rightwards, therefore, the patient in the clinic hall can see the information such as the number arrangement prompt displayed by the display screen at the left side end and the right side end in the hall as far as possible.

As shown in fig. 1, 2 and 3, after the display detection circuit is powered on, when the multimedia triage screen body works normally and the screen emits light, the light receiving surface of the photosensitive resistor RL is illuminated, and the resistance is small at about 100K, so that the positive electrode of the 12V power supply is subjected to voltage reduction and current limitation by the photosensitive resistor RL and then enters the base voltage of the NPN triode Q1 which is higher than 0.7V, the NPN triode Q1 is conducted with the collector to output a low level and enters the negative power input end of the relay K1, the relay K1 is powered on to pull in the control power input end and the normally closed contact end to be open, and thus, the wireless transmitting circuit module a4 cannot be powered on to. When the screen does not emit light when the multimedia triage screen body does not work normally, the light receiving surface of the photoresistor RL is not illuminated, the resistance is larger than about 10M, therefore, the voltage of the positive electrode of a 12V power supply is reduced by the photoresistor RL and limited, then the voltage enters the base of the NPN triode Q1 and is far lower than 0.7V, the voltage of the base of the NPN triode Q1 is cut off, the collector does not output low level any more, the low level enters the negative power supply input end of the relay K1, the relay K1 is not electrified any more, the control power supply input end and the normally closed contact end are closed, and therefore the wireless transmitting circuit module A4 can work electrically (the normally closed contact end of the relay K1. Since the two contacts of the first wireless transmission key S1 of the wireless transmission circuit module a4 are connected together in advance through the wires, the wireless transmission circuit module a4 will transmit the first path of wireless closed signals at this moment (the two contacts of the second, third and fourth wireless transmission keys S2, S3 and S4 of the wireless transmission circuit modules of the other three clinics are connected together in advance through the wires, so the second, third and fourth paths of wireless closed signals are transmitted respectively).

As shown in fig. 1, 2 and 3, the power switch S1 is turned on by the operator at ordinary times, and the wireless receiving circuit module a5 is powered on. When the wireless transmitting circuit module a4 of the four visiting halls respectively transmits a first path, a second path, a third path and a fourth path of wireless closing signals, and the wireless receiving circuit module a5 respectively receives the wireless closing signals, the

pins

4, 5, 6 and 7 respectively output high levels, the high levels are subjected to voltage reduction and current limitation through the resistors R1, R2, R3 and R4 and enter the positive power input ends of the light emitting diodes VL, VL1, VL2 and VL3, so that the light emitting diodes VL, VL1, VL2 and VL3 respectively emit light to prompt which visiting hall's multimedia triage screen body 1 has a problem. The manager can maintain the multimedia triage screen body 1 for the first time by watching the different light-emitting diodes (the shell 61 at the side end of each light-emitting diode can be printed with characters, such as 1 and 2 respectively represent a first and a second clinic).
