As shown in fig. 1 and 2, the two power output ends of the solar panel G and the two power poles of the storage battery G1 are connected by wires respectively. The positive electrode of the storage battery G1 is connected with the control power input end of the relay K9 of the signal generator through a wire. The normally open contact end of the relay K9 at the control power output end of the signal generator, the negative electrode of the storage battery G1 and the power input end of the generator open circuit and short circuit detection mechanism are respectively connected with the control power input end of the relay K8 and the negative power input end of the relay K4 through wires. The two poles of the power supply of the storage battery G1 and the 1 and 2 pins of the power supply input two-end short message module A5 of the short message prompt circuit are respectively connected through wires. The normally closed contact ends of the relays K at the 1, 2 pins and the signal output end of the photoelectric switches A1 at the positive and negative electrode power input ends of the three photoelectric detection switches of the blade detection mechanism are respectively connected with the inner side ends of the three slip rings X1, X2 and X3 through wires. The third metal sheet T3, normally closed contact ends of relays K7, K6 and K5 at three paths of signal output ends of the generator open circuit and short circuit detection mechanism, a shell of the wind driven generator body M1 and the other ends of resistors R1, R2, R3, R4 and R5 at five paths of signal input ends of the short message prompt circuit are respectively connected through wires. The power output end of the wind power generation body M1 is connected with four control power input ends of a relay K of the generator open circuit and short circuit detection mechanism through wires. The four normally-closed contact ends of the relay K at the output end of the control power supply of the open circuit and short circuit detection mechanism of the generator and the electric equipment of the wind power generation body M1 are connected through wires.

As shown in fig. 1 and 2, the solar panel G is illuminated to generate electric energy to charge the storage battery G1, so as to ensure the working power supply requirement of the back-stage circuit. The wind driven generator body M1 is acted by wind power to generate electric energy at ordinary times, so that an alternating current power supply (such as 220V) output by a live wire and a zero wire of a three-phase four-wire (such as 380V) enters two ends of the power supply input of the relay K8 through the diode VD, and the relay K8 is electrically attracted to open the control power supply input end and the normally closed contact end. Because the positive electrode of the storage battery G1 is connected with the control power input end of the relay K8 (through the normally open contact end of the relay K9), and the normally closed contact end of the relay K8 is connected with the positive power input end of the open circuit and short circuit detection mechanism of the generator, the open circuit and short circuit detection mechanism of the generator cannot work when the generator body M1 normally generates electricity and fails. The two poles of the power supply output by the storage battery G1 enter the power supply input two ends of the blade detection mechanism through two metal sheets T1 and T2 and two slip rings X1 and X2 (when the generator body M1 is rotated by wind power to blow the blades, the three slip rings X1, X2 and X3 rotate, the three metal sheets T1, T2 and T3 do not rotate, the three slip rings X1, X2 and X3 are kept in electrical contact with each other, the normally closed contact ends of the three relays K, K and K2 are communicated with the 3 pin (the other end of the resistor R1) of the short message module A5 through the slip rings X3 and the third metal sheet T3), so that the blade detection mechanism is in an electric working state (meanwhile, the 12V power output by the storage battery G1 enters the power supply input two ends of the short message prompt circuit, and the short message prompt circuit is electrically operated). When three blades of the wind driven generator body M1 do not fall off, the detecting heads of the three photoelectric switches A, A and A2 are blocked by the detecting heads, the 3 feet of the detecting heads output high level to enter the positive power input ends of the three relays K10, K1 and K2 respectively, so that the three relays K10, K1 and K2 are powered on to attract the control power input ends and the normally closed contact ends of the three relays K10, K1 and K2 respectively to open, and then the 3 feet of the short message module A5 cannot be input with trigger signals. In practical situations, as long as one blade 101 falls off, the 3 pins of any one of the photoelectric switches A or A1 and A2 can stop outputting high level due to no shielding object before the detection head, and then the control power input end and the normally closed contact end of the relay K10 or K1 and K2 can lose electricity, so that the low level can be led to enter the 3 pins of the short message module A5 through the voltage reduction and current limiting of the resistor R1 after the control power input end (connected with the cathode of the storage battery G1) and the normally closed contact end of any one of the relay K10 or K1 and K2 lose electricity, and thus, the short message module A5 can send the pre-stored short message blade falling off under the action of an internal circuit thereof, and a manager mobile phone connected with the short message module A5 can intuitively know that the blade falling phenomenon of the generator body M1 occurs on site, and the manager can timely and pointedly remove the fault of the wind power generator body on site and recover the normal work of the generator body within the time as fast as possible.

As shown in fig. 1 and 2, when the wind driven generator body M1 fails and does not generate electricity, the relay K8 loses electricity, and the control power supply input end and the normally closed contact end of the relay are closed, so that the generator open circuit and short circuit detection mechanism is in an electricity-getting state. In practical situations, when the surrounding environment is windy, the wind power signal generator M generates electric energy to enter the two ends of the power input of the relay K9, so that the control power input end and the normally open contact end of the relay K9 are closed by the power suction of the relay K9, and when the surrounding environment is windy, the control power input end of the relay K8 is powered on only because the control power input end of the relay K8 is connected with the normally open contact end of the relay K9, and further, the open circuit and short circuit detection mechanism of the generator is powered on. When the surrounding environment is windless, the wind power signal generator M does not generate electricity and enters the two ends of the power input of the relay K9, so that the relay K9 is not powered off, the control power input end and the normally open contact end of the relay K9 are not attracted, and the control power input end of the relay K8 is connected with the normally open contact end of the relay K9, so that the control power input end of the relay K8 cannot be powered on when the surrounding environment is windless, and then the open circuit and short circuit detection mechanism of the generator cannot be powered on. Through the circuit function, when the generator body M1 fails and does not generate electricity and the surrounding environment has wind, the open circuit and short circuit detection mechanism of the generator can work electrically; unnecessary power-on operation of the on-site windless, open-circuit and short-circuit detection mechanism of the generator (no fault occurs in the generator body M1, no power generation is caused by the on-site windless) is prevented, and the performance of the generator body M1 is detected unnecessarily.

As shown in fig. 1 and 2, when the generator body M1 fails, after the generator open circuit and short circuit detection mechanism is powered, the relay K (actually may use a contactor) is in a power-off state, and then the power output by the generator body M1 enters the power supply line through four control power input ends and four normally closed contact ends of the relay K, so as to normally supply power to the electric equipment. When the generator body M1 breaks down, the positive power supply output by the normally closed contact end of the relay K8 can enter the positive power supply input end of the relay K and the time control switch A4, so that the relay K is electrified to attract the four control power supply input ends and the four normally closed contact ends to open a circuit respectively, and the situation that if a temporary standby power supply is adopted by an electric equipment end, the power supply returns to the four power supply output ends of the generator body M1 is prevented, and further the normal operation of the open circuit and short circuit detection mechanism of the generator is influenced. Under the action of the internal circuit and the 3 and 4-pin output power supply time set by a technician after the time control switch A4 is electrified, an output power supply enters two ends of the power supply input of the relay K4 at intervals of 3 seconds, so that the control power supply input end and the normally open contact end of the relay K4 are electrified and attracted, and the positive power supply of the storage battery G1 enters a zero line of the three-phase four-wire power supply of the generator body M1 through the control power supply input end and the normally open contact end of the relay K4. Under the actual condition, when a serious fault occurs in the wind driven generator body M1, internal coils burn out and the like and are directly grounded on the shell of the wind driven generator body M1, the positive power supply of the storage battery G1 can directly pass through the shell and is reduced in voltage and limited in current through the resistor R5 to enter the base electrode of the NPN triode Q1, the NPN triode Q1 is conducted with the collector electrode to output low level and enter the 7 feet of the short message module A5, and therefore the short message module A5 sends out a short message 'short circuit' stored in advance under the action of an internal circuit of the short message module A5, and after receiving the short message, a manager mobile phone connected with the short message module A5 can intuitively know that the short circuit phenomenon of the coil of the wind driven generator body M1 occurs on site, and the manager can timely and pertinently remove the fault of the wind driven generator body on site to recover the normal operation of the wind driven generator body within the time as fast as possible. After the relay K4 is electrified, the positive electrode of the power supply input by the zero line of the generator body M1 also enters the positive electrode power supply input ends of the three relays K5, K6 and K7 through three phase lines, and the control power supply input ends and the normally closed contact ends of the three relays K5, K6 and K7 are electrified to be attracted to be open. Because the control power supply input ends of the relays K5, K6 and K7 are connected with the negative electrode of the storage battery G1, the normally closed contact ends of the relays K5, K6 and K7 are respectively connected with the

pins

4, 5 and 6 of the short message module A5 (the resistors R2, R3 and R4 are used for reducing voltage and limiting current), so that the phenomenon that the relays K5 or K6 and K7 lose electricity and are not connected with the control power supply input ends of the relays and the normally closed contact ends is caused as long as any one phase line is opened, the

pins

4 or 5 and 6 of the short message module A5 are input with low-level signals, the short message module A5 can send a pre-stored short message of 'first phase line open circuit' or 'second phase line open circuit' or 'third phase line open circuit' under the action of an internal circuit, and a manager mobile phone which is connected with the short message module A5 can intuitively know that the phenomenon of the first phase line or the second phase line and the third phase line open circuit occurs on site, and the manager can timely and timely get rid of the body open circuit of the wind driven generator in the site and recover the normal operation within the time as soon as possible. In the invention, taking the wind driven generator body M1 as a three-phase four-wire 380V power generation and taking an example, only a single phase wire of a power supply output by three phase wires of normal power generation respectively enters the relay K5 or K6 and K7, so that the relay K5 or K6 and K7 can not be powered. In fig. 2, the resistances R1, R2, R3, R4, R5 are 10K; the relays K, K, K1, K2, K4, K5, K6, K7, K9 are DC12V relays; the relay K8 is an alternating current 110V relay; the model of the diode VD is 1N4001 (the diode VD mainly plays a role in unidirectional conduction, and prevents the positive pole of a 12V power supply from directly entering the positive pole power supply input end of the relay K7 through the control power supply input end of the relay K8 and the normally closed contact end, so that whether the third phase line of the generator body M1 is open or not cannot be detected); NPN triode Q1 model 9013.
