[0021] Figure 1 , 2As shown in Figure 3, the present invention is based on the vertical hanging basket equipment body 4. The staff in the vertical hanging basket equipment body 4 controls the working mode of the electric lifting mechanism 3, and then the reel of the electric lifting mechanism 3 drives the basket body 2 to rise or fall through the wire rope 31, so that the staff can work at the corresponding height. When the staff controls the basket 2 to move up or down, the outer side of the wheel 9 of the generator M rotates along the inner side of the guide rail 1 to generate AC power, and the AC power is rectified by the bridge pile W2 and filtered by the capacitor C1 to be converted into DC power. The 220V AC power enters the power input end of the power module W1, and the power output end of the power module W1 outputs a 12V DC power that enters the power input end of the control circuit; the 220V AC power enters the power input end of the power module AW5, and the power output end of the power module AW5 outputs a 12V DC power that enters the power input end of the receiving circuit. When the basket moves up or down at an appropriate speed and the voltage of the electric energy generated by the generator M is relatively low (for example, lower than 6V), the voltage is divided by resistors R1 and R2 and enters the 2nd pin of the three-terminal voltage detector W3. The voltage is lower than the 4.75V threshold voltage inside the three-terminal voltage detector W3, and the 1st pin of the three-terminal voltage detector W3 outputs a low level. The relay K1 will not be energized and closed, and the wireless transmitting circuit module W4 will not transmit a wireless closing signal, and the corresponding basket moves up and down normally. When the speed of the basket moving up or down is inappropriately high (for example, the wire rope is broken, the weight in the basket is too large, or the motor speed of the electric lifting mechanism 3 is too high), the voltage of the electric energy emitted by the generator M is relatively high (for example, higher than 6V), and the voltage is divided by resistors R1 and R2 and enters the 2nd pin of the three-terminal voltage detector W3. The voltage is higher than the 4.75V threshold voltage inside the three-terminal voltage detector W3, and the 1st pin of the three-terminal voltage detector W3 outputs a high level and enters the base of the transistor Q1 through the resistor R3 for voltage reduction and current limiting. The transistor Q1 is turned on and the collector outputs a low level and enters the negative power input terminal of the relay K1. The relay K1 is energized to close its control contact terminal and the normally open contact terminal. Since the two contacts under the first signal transmission button D1 of the wireless transmission circuit module W4 are connected together, the wireless transmission circuit module W4 will transmit the first wireless closing signal. After the wireless receiving circuit module W5 receives the first wireless closing signal, its 3rd pin outputs a high level and enters the power input end of the multiple sets of electromagnet DC. The multiple sets of electromagnet DC generate suction, and the steel armature plate 83 moves toward the inner end through the connecting rod 82 along the opening 84 of the electromagnet under the strong magnetic force, and the inner side of the limit plate 85 and the connecting rod move toward the inner side of the guide rail 1. The distance between the limit plates 85 and the connecting rod of each two laterally distributed electromagnetic fixing mechanisms 8 is smaller than the width of the guide wheels on both sides of the frame of the basket 2. In this way, due to the limiting effect of the limit plates 85 and the connecting rod, the basket will drop to a certain height, and the lower end will be stuck between the limit plates 85 and the connecting rod of each two laterally distributed electromagnetic fixing mechanisms 8, and will no longer drop in height.The subsequent staff eliminated the fault of the vertical hanging basket equipment body 4. After turning off the power switch S1, the wireless transmitting circuit module W4 no longer transmitted the wireless signal, and the 3rd pin of the wireless receiving circuit module W6 no longer outputted a high level. Then, the power input end of the multiple sets of electromagnets DC lost power, and the multiple sets of electromagnets DC no longer generated suction. Under the outward force of the spring 81, the armature plate 83 moved toward the outer end along the opening 84 of the electromagnet through the connecting rod 82, and the inner side of the limit plate 85 and the connecting rod moved toward the outside of the guide rail 1. The inner side of the limit plate 85 and the connecting rod no longer limited the downward movement of the basket. The present application can control the up or down movement of the basket.

[0022] Figure 1 , 2 As shown in Figure 3, through the above, in the application, the generator and the rectifier comparison circuit can monitor the speed of the basket in real time. When the speed is too fast, the control circuit can wirelessly transmit a wireless signal. After the receiving circuit receives the wireless control signal, it can timely control the outer sides of the connecting rods of the multiple electromagnetic fixing mechanisms to extend out of the guide rails to limit the basket, thereby preventing the basket from descending too fast or even falling to the ground, causing the possibility of personal injury accidents.
