The wind vane electromagnet coil is connected with the rectifier bridge through the KM2 normally open switch of the wind vane electromagnet control contactor circuit.

[0022] A device for controlling the release circuit of the rotary wind vane of the tower crane by the SMS of the UPS power supply, as shown in Figure 1 The device includes a wind vane release circuit, a UPS power supply module, a SMS receiving module, a control circuit module and a state feedback module. The UPS power supply module is connected with the wind vane release circuit, the SMS receiving module and the control circuit module for power supply. The SMS receiving module is connected with the control circuit module. The collection end of the state feedback module is connected with the wind vane release circuit, and the output end of the state feedback module is connected with the control circuit module. The UPS power supply module is connected with the mains through the normally closed auxiliary switch of the AC contactor for control charging.

[0023] The UPS power supply module is used to provide uninterrupted power supply, to ensure that the system can still work continuously when the mains power is off, and to protect the wind vane release function. The SMS receiving module receives the SMS instructions sent by the remote user, analyzes the instruction content, and generates corresponding control signals. The control circuit module generates signals through the control relay to realize the wind vane release function. The state feedback module is used to receive the wind vane release state (such as released, unreleased, etc.), and feedback to the remote operator through SMS to ensure the closed-loop feedback of operation.

[0024] UPS power module: A UPS power supply device with a capacity of 1000VA or more is used to provide power support for the control system and SMS module. When the mains power is normally supplied, the UPS is charged. When the mains power is cut off, the UPS can maintain the normal operation of the entire system for a short time to ensure that the tower wind vane can be released in time. The UPS power supply can be customized according to the power supply requirements of the tower to ensure the long-term operation and reliability of the equipment. SMS receiving module: This module includes a GSM (or 4G / 5G) communication module for receiving SMS instructions from remote control personnel. SMS instructions can be sent in a specific format, such as "#01RELEASE#", which represents a wind vane release instruction. The system receives the information and converts it into a control signal through a parser. Control circuit module: This module is based on a single-chip microcomputer, which is the smallest system of the existing 52 series or the smallest system of STM32 according to the price. Through the received SMS control signal, the relay drives the wind vane release device. State feedback module: This module is connected to the SMS control module and monitors the state information of the wind vane release in real time, and sends it to the mobile phone of the remote operator through SMS, ensuring that the operator can master the real-time state. Feedback content includes the current state of the wind vane (locked / release), UPS power supply working state, etc. The state feedback module is an existing acquisition module that collects and feeds back data.

[0025] Working process:

[0026] (1) When meteorological monitoring or severe weather warnings are issued, remote operators send SMS instructions to the system's control module through their mobile phones. The SMS receiving module of the system parses the SMS and generates a control signal.

[0027] (2) The control circuit module receives the control signal and is powered by the UPS to drive the wind vane release device to perform the release action.

[0028] (3) After the wind vane is released, the state feedback module sends the execution result to the operator through SMS to confirm the operation is completed.

[0029] (4) If the mains power is interrupted during severe weather, the UPS power module will automatically switch to backup power to ensure that the SMS control and wind vane release device can continue to work until the operation is completed.

[0030] The above is only the preferred embodiment of the present application, and it should be noted that for ordinary skilled personnel in the technical field, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should be considered within the scope of protection of the present application.
