After the 220V alternating current power supply enters the power supply input end of the stabilized power supply U1, the stabilized power supply U1 outputs stable direct current 12V power supply under the action of an internal circuit of the stabilized power supply U1, the stable direct current 12V power supply enters the power supply input ends of the password mechanism, the wireless receiving mechanism and the prompting circuit, and the circuits and the mechanisms are in a power-on working state. In the utility model, the relay K9 is in a power-off state in an initial state, the control power supply input end and the normally open contact end are in open circuit, so that the main power supply input end of the computer body is powered off, other irrelevant personnel press the power-on key of the computer body, and the computer body cannot be started because the computer body is not powered on, namely, a reinstallation system is not installed or a hard disk is damaged in a formatting mode. Before the wireless remote control device is used, a machine owner can set a starting password in a dynamic wireless non-contact mode through the wireless remote control boards U5 and U6 (for example, one starting password is set every other week), after the machine owner presses a first wireless signal transmission key D1 of the wireless remote control board U5 or U6 (or a second wireless signal transmission key D2, a third wireless signal transmission key D3 and a fourth wireless signal transmission key D4 of the wireless remote control board U5 or U6) respectively (or one transmission key is pressed once in password setting), the wireless remote control board U5 or U6 can transmit a first path of wireless closing signals (or a second path, a third path and a fourth path of wireless closing signals). After the wireless receiving circuit module U2 or U3 receives the first path of wireless closing signal (or the second path, the third path, and the fourth path of wireless closing signal), the 4-pin (or the 5, 6, and 7-pins) of the wireless receiving circuit module U2 or U3 outputs a high level, and the high level is subjected to voltage reduction and current limitation by the resistor R2 (or the R3, the R4, the R5, the R6, the R7, the R8, and the R9) to enter the base of the NPN triode Q9 (or the Q9, and the Q9), so that the NPN triode Q9 (or the Q9, the K9, the negative pole of the power supply, the normally-closed or open-switch-contact, the power supply control terminal, the normally-closed control terminal, the power-open-switch terminal, the power-switch terminal and the power-switch control terminal 9. When the computer host presses the first wireless signal emitting key D1 of the wireless remote control board U5 or U6 again (or the second wireless signal emitting key D2, the third wireless signal emitting key D3, and the fourth wireless signal emitting key D4 of the wireless remote control board U5 or U6), the wireless remote control board U5 or U6 emits the first wireless open circuit signal (or the second wireless open circuit signal, the third wireless open circuit signal, and the fourth wireless open circuit signal). After the wireless receiving circuit module U2 or U3 receives the first path of wireless open-circuit signal (or the second path, the third path, and the fourth path of wireless open-circuit signal), the pin 4 (or

pins

5, 6, and 7) of the wireless receiving circuit module U2 or U3 stops outputting high level through the resistor R2 (or pins R3, R4, R5, R6, R7, R8, and R9) to the base of the NPN transistor Q1 (or the transistor Q2, Q3, Q4, Q5, Q6, Q7, and Q8), so that the NPN transistor Q1 (or the transistor Q2, Q3, Q4, Q5, Q6, Q7, and Q8) is turned off, and further the K1 (or the input terminals K2, K3, K4, K5, K6, K7, and K8) is no longer powered on, and the normally-open-closed input terminals and the normally-open-closed contacts are controlled.

As shown in the figures 1 and 2, when a user controls a relay K (or K, K) to be powered on through a wireless remote control panel U and U, if the relay K (or K, K) is powered on and attracted, the owner knows a password formed by the relay K (or K, K) and needs to open a computer body to start up, presses down a first power switch S (or S, S) and enters the input end of a control power supply and the normally open contact end of the relay K (or K, K) at the moment, the positive pole of a 12V power supply enters the input end of the positive power supply of the relay K through the input end of the control power supply and the normally open contact end of the relay K (or K, K) at the moment, then the relay K9 gets the electricity to attract the control power input end and the normally open contact end to be closed, thus the 220V power can enter the power input end CZ of the computer body through the relay K9 control power input end and the normally open contact end, the main power input end CZ of the computer body gets the electricity, after the computer owner presses the power-on key of the computer body, the computer body 1 can be started, and the follow-up computer owner can normally use the computer body. In practical situations, when the owner of the computer is powered by the wireless remote control panel U5, U6 to control the relay K1 (or K2, K3, K4, K5, K6, K7, K8) to form a password, other non-permitted persons press any other power switch except the first power switch S1 (or S2, S3, S4, S5, S6, S7, S8) without knowing the password, which will cause the positive pole of the 12V power supply to control the power input end and the normally closed contact end through the relay K1 (or K2, K3, K4, K5, K6, K7, K8), trigger the conduction through the resistor R1, electrically pull the control power input end and the normally closed contact end of the relay K, so that the 220V power supply enters the K9 control power supply relay, that is not to enter the K9 control the power supply input end, that is not pressed, that is, even if the non-permitted persons press any other power switches (S72, S9) or any other current limiting switch S9, after the relay K1 (or K2, K3, K4, K5, K6, K7 and K8) is electrified to attract the control power supply input end and the normally open contact end of the relay K1 to be closed, because the 220V alternating current power supply does not enter the control power supply input end of the relay K9 at the moment, the main power supply input end of the computer body cannot be electrified, other non-permitted personnel cannot start the computer body by pressing a switch key of the computer body, and the good confidentiality purpose is achieved. Through the above, the user can conveniently set the starting password at intervals in a wireless non-contact mode dynamically according to needs, and the situation that the starting cannot play a secret role when other people know the fixed password is avoided (the password switch is set at intervals to prevent the user from always using one password, and other people can open the computer body 1 after knowing the password switch). In the utility model, if any power switch except the power switch (such as power switches S1 or S2, S3, S4, S5, S6, S7 and S8) is pressed down because other unrelated persons do not know the power-on password, the trigger sub-circuit can be triggered to disconnect the input 220V power supply, and the computer body can not be powered on.

As shown in fig. 1 and 2, after the power supply of the prompting circuit works, as long as other non-permitted persons press the power switch by mistake, after the thyristor VS is turned on (when the power switch is pressed correctly, the thyristor VS cannot be turned on), the high level can be reduced by the resistor R10 to limit the current and enter the base of the NPN triode Q9, the NPN triode Q9 turns on the collector to output the low level and enter the first trigger signal input end 3 of the short message module U4, so that the short message module U4 sends out a pre-stored short message under the action of its internal circuit, and after receiving the short message, the mobile phone of the owner connected with the short message module can know that someone is not permitted to start up at the first time, and the owner can timely master the field condition and take corresponding measures (for example, timely arrive at the field or inform the nearby person on duty to view the situation). The utility model prevents the defects that the prior computer can only prevent other people from illegally tampering or stealing related data and information from the aspect of software due to the structural limitation, can not prevent the power-on of a computer mainboard, a power supply module and the like, and has the probability that other people damage the computer by reinstalling a system or formatting a hard disk. It should be noted that the number of sets of wireless transmitting circuit modules adopted in the present invention is not two fixed sets, the number of wireless receiving circuit modules is not two fixed sets, the number of resistors, NPN triodes, and relays of the wireless receiving mechanism is also not eight fixed sets, more sets of wireless transmitting circuits and wireless receiving circuits are adopted, and more sets of resistors, NPN triodes, and relays are adopted to form more cipher numbers (for example, four sets of wireless transmitting circuit modules and wireless receiving circuit modules are adopted, and sixteen resistors, NPN triodes, and relays are respectively adopted to form 16 ciphers, so as to achieve better confidentiality effect). In the circuit, the resistances of the resistors R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 are 1K; the model of the NPN triode Q1, Q2, Q3, Q4, Q5, Q6, Q7, Q8 and Q9 is 9013; relays K1, K2, K3, K4, K5, K6, K7, K8, K9, the K model is DC 12V; the power switches S1, S2, S3, S4, S5, S6, S7 and S8 are normally open contact self-locking power switches; the VS model of the controlled silicon is MCR 100-1; the short message module U4 is a short message alarm module of type GSM 800, the finished short message alarm module U4 has two
