After the power switch K is turned on, the temperature prompting circuit, the first timing circuit and the second timing circuit are all in a power-on working state. When a user works or learns, the body of the user can block infrared light beams emitted by an emitting head of the photoelectric detection switch A in a straight line, then, a high level (12V) output by a pin 3 of the photoelectric detection switch A controls a power supply input end and a normally closed contact end through a relay J2, and the voltage is reduced and the current is limited through an adjustable resistor RP1 to charge an electrolytic capacitor C; during the charging of the electrolytic capacitor C by the 12V power supply through the adjustable resistor RP1, when the electrolytic capacitor C is not fully charged in the initial 40-minute time period, the power supply after voltage reduction and current limitation is carried out through the adjustable resistor RP1 and the resistor R2, the base voltage of the NPN triode Q1 is lower than 0.7V, the NPN triode Q1 is in a cut-off state, the relay J1 cannot be electrified for attraction, the buzzer B cannot be electrified, and the user can temporarily do not need to move at the moment. After the electrolytic capacitor C is fully charged for 40 minutes, at the moment, a rear power supply which is subjected to voltage reduction and current limitation through the adjustable resistor RP1 and the resistor R2 enters an NPN triode Q1, the base voltage is higher than 0.7V, the NPN triode Q1 is conducted, the collector of the NPN triode Q1 outputs low level and enters the negative power supply input end of the relay J1, and then the relay J1 is electrified to attract the control power supply input end and the normally-open contact end of the relay to be closed. Because the normally open contact end of the relay J1 is connected with the positive power supply input end of the buzzer B, after 40 minutes, the buzzer B can be electrified to sound, and the user is prompted to sit on the chair for enough time and needs to move for a period of time (move outside the detection range of the detection head of the photoelectric detection switch A).
As shown in fig. 1, 2 and 3, when the relay J1 is electrified to attract the buzzer B to sound, the 12V power supply charges the electrolytic capacitor C1 through the adjustable resistor RP2, and when the electrolytic capacitor C1 is not fully charged in the initial 10-second period, the power supply after voltage reduction and current limitation is performed through the adjustable resistor RP2 and the resistor R1, the base voltage of the NPN triodes Q2 and Q3 is lower than 0.7V, the NPN triodes Q2 and Q3 are in a cut-off state, the relays J2 and J3 are not electrified to attract, and then the buzzer B continues to be electrified to sound. After the electrolytic capacitor C1 is fully charged after charging for 10 seconds, at the moment, the power supply after being subjected to voltage reduction and current limitation by the adjustable resistor RP2 and the resistor R1 enters the base voltage of the NPN triode Q2 to be higher than 0.7V, the NPN triode Q2 is conducted, the collector of the NPN triode Q2 outputs low level and enters the negative power supply input end of the relay J2, and then the relay J2 is electrified to pull in the control power supply input end and the normally closed contact end to be open; meanwhile, the voltage of the power supply after being reduced and limited by the adjustable resistor RP2 and the resistor R1 enters the base of the NPN triode Q3, the voltage is higher than 0.7V, the NPN triode Q3 is conducted, the collector of the NPN triode Q3 outputs low level and enters the negative power supply input end of the relay J3, and then the relay J3 is electrified to pull in the control power supply input end and the normally open contact end of the relay J3 to be closed. Because the 3 feet of the photoelectric detection switch A are connected with one end of the adjustable resistor RP1 through the control power input end and the normally closed contact end of the relay J2, after a user sits for more than 40 minutes for a long time, the buzzer B sounds, and the relay J2 is electrified at intervals of 10 seconds, the high level output by the 3 feet of the photoelectric detection switch A does not enter the other end of the adjustable resistor RP1 any more (even if the user still sits on a chair after hearing the buzzer B sounds, the 3 feet of the photoelectric detection switch A still output high level, but because the relay J2 is electrified, the power input end and the normally closed contact end are closed, the high level output by the 3 feet of the photoelectric detection switch A also temporarily does not enter the other end of the adjustable resistor RP 1); because no high level continues to charge the electrolytic capacitor C, after a period of time (2 seconds) the voltage charged on the electrolytic capacitor C is released through the NPN triode Q1 and the relay J1, the relay J1 loses power and does not pull the input end of the control power supply and the normally open contact end to open a circuit any more, the buzzer B is not electrified to sound any more, and the anode of the 12V power supply does not charge the electrolytic capacitor C1 any more through the adjustable resistor RP 2. After the relays J2 and J3 are powered on and attracted simultaneously, even if 3 feet of the photoelectric detection switch A have high level output (if a user hears that the buzzer B sounds to leave the chair to move, the 3 feet of the photoelectric detection switch A do not output high level any more), when the relay J2 cuts off the space between the 3 feet of the photoelectric detection switch A and the other end of the adjustable resistor RP1, because the relay J3 controls the input end of the power supply to be grounded, the normally-open contact end of the relay J3 is connected with the input end of the cathode power supply of the electric bead H, the input end of the anode power supply of the electric bead H is communicated with the anode of the electrolytic capacitor C, the electric bead H can be powered on for about 2 seconds at the moment, the voltage charged by the electrolytic capacitor C is rapidly released (after 2 seconds, the voltage charged by the electrolytic capacitor C is released completely, the NPN triode Q1 is cut off, the relay J1 is powered off to control the input end of the, The electrolytic capacitor C is ready for timed charging. After 10 seconds, the electrolytic capacitor C1 is fully charged and the electric relays J2 and J3 are powered on and pulled, because the electric relay J1 is powered off, about 2 seconds later, the output power supply is not charged for the electrolytic capacitor C1, the voltage charged on the electrolytic capacitor C1 can maintain the NPN triodes Q2 and Q3 to be continuously conducted for 3 seconds, and the electric relays J2 and J3 are continuously powered for 3 seconds; after 3 seconds, the voltage charged on the electrolytic capacitor C1 is released, the NPN triodes Q2 and Q3 are cut off, then the relays J2 and J3 lose power, so that the relay J2 controls the power supply input end to be closed with the normally closed contact end, the high level output by the 3 pin of the photoelectric detection switch A enters the other end of the adjustable resistor RP1 again (when a user does not sit on the chair and does not block infrared light emitted by a detecting head of the photoelectric detection switch A in a straight line, no high level enters the adjustable resistor RP 1), if the user hears the sounder B, even if the user does not leave the chair, the sounder B loses power after the sounder B sends out sound for 10 seconds in total. After the buzzer B is powered off and sounds, if a user sits on a chair, the 3 feet of the photoelectric detection switch A outputs high level again, the high level is reduced in voltage and limited in current through the adjustable resistor RP1, the electrolytic capacitor C is charged, after the electrolytic capacitor C is fully charged at intervals of 40 minutes, the buzzer B is powered on to give a prompt sound for 10 seconds, the process is continuously circulated, and when the buzzer B is used, the user sits on the chair for more than 40 minutes continuously as long as the user does not turn off the power switch K, the buzzer B is powered on to give a prompt sound for 10 seconds, and the user is prompted to move for a period of time (the user returns to the chair after moving, and the electrolytic capacitor C starts to be recharged for timing).
As shown in fig. 1, 2 and 3, the temperature of the case of the office computer can be detected simultaneously according to the requirement (the vacuum chuck is sucked at the side end of the case, and the temperature sensing surface of the thermistor RT is tightly attached to the case). In the temperature prompting circuit, when the temperature of the case is not high and is lower than a certain temperature (such as 42 ℃), the resistance value of the thermistor RT is relatively high, so that the voltage of a power supply which is subjected to voltage reduction and current limitation by the adjustable resistor RP3 and enters a control electrode of the silicon controlled rectifier VS is lower than 0.8V, the silicon controlled rectifier VS cannot be triggered and conducted, and the buzzer B does not sound. When the temperature of the case is too high and is higher than a certain value (for example, higher than 42 ℃), the resistance value of the thermistor RT is relatively small, so that the voltage of a power supply which is subjected to voltage reduction and current limitation through the adjustable resistor RP3 is higher than 0.8V, the voltage of a voltage entering the control electrode of the silicon controlled rectifier VS is triggered to conduct the cathode of the silicon controlled rectifier VS, a high level is directly output to enter the input end of the positive power supply of the buzzer B, and then the buzzer B is electrified to give a loud prompt sound (until the power switch K is turned off) to prompt a user that the temperature of the case is too high, and the use of a computer is temporarily stopped or cooling measures are taken (when the buzzer B continuously sounds for more than 10 seconds, the case temperature. Fig. 3 shows NPN transistors Q1, Q2, and Q3 model number 9013; relays J1, J2, J3 are mini relays of model DC 4100; the thermistor RT is a negative temperature coefficient thermistor of type NTC 103D; the buzzer B is an active continuous sound micro buzzer of the model HNB09A 12; the electric bead H is a 12V miniature small electric bead; the specification of the electrolytic capacitor C, C1 is 1000 mu F/25V and 10 mu F/25V respectively; the specifications of the adjustable resistors RP1, RP2 and RP3 are 5M (adjusted to 2.18M), 2M (adjusted to 0.9M) and 10M ((adjusted to 6.4M). the controllable silicon VS is a plastic-sealed unidirectional controllable silicon with the model of MCR100-6, and the resistances of the resistors R1 and R2 are 470K.
