[0031] As can be seen from the above description, by arranging a gyroscope chip in the induction unit, the attitude change of the crane boom can be monitored through the gyroscope chip. When it is detected that the boom moves up and down, it indicates that the crane starts to operate.

[0033] As can be seen from the above description, the induction unit is powered by the solar panel, reducing the later maintenance of the power supply; at the same time, since the start of the induction unit is controlled by the gyroscope chip, the energy consumption of the induction unit is reduced. Therefore, based on the solar panel, the power supply demand of the induction unit can be met.

[0036] Further, the receiving unit includes a handheld type and a wearable type; the handheld receiving unit is provided with a handle; the wearable receiving unit includes a watch band.

[0037] As can be seen from the above description, using the handheld type and the wearable type as the receiving unit can meet the usage requirements of the receiving unit in different scenarios.

[0040] Further, a display screen and a button are also provided on one side of the receiving unit.

[0041] As can be seen from the above description, by providing a display screen and a button on the receiving unit, and through the cooperation of the button and the display screen, multi-voltage gear adjustable voltage detection can be realized, enabling the user to flexibly select the alarm gear. The higher the voltage gear, the farther the alarm distance, so as to meet the application of the user in a complex electric field environment.

[0042] Further, the handheld receiving unit is provided with a handle.

[0043] As can be seen from the above description, by providing a handle on the handheld receiving unit, the receiving unit is more convenient to operate.

[0044] Further, the wearable receiving unit includes a smart watch or a bracelet.

[0045] As can be seen from the above description, using a smart watch or bracelet as the wearable receiving unit enables the receiving unit to be directly worn on the hand, making it more convenient to use.

[0046] Further, the first induction antenna and the second induction antenna include Lora antennas.

[0047] As can be seen from the above description, adopting low-power Lora communication can reduce the energy consumption of the induction unit and the receiving unit, thereby effectively extending the standby duration of the induction end.

It judges whether the device is undergoing an attitude change by the direction or rotation state of the induction unit 1 in space. If the change exceeds the preset threshold, it is inferred that the boom is in displacement, and the recognition is enabled to reduce the power consumption of the induction end; the cooperation control and data transmission between each module are realized through a main control chip such as an MCU.

For example, users can flexibly select the alarm gear, and the higher the voltage gear, the farther the alarm distance, to meet the application of users in complex electric field environments.

[0055] At the same time, data such as alarm information and power information can be pushed to the remote end through 4G or Bluetooth.

The wearable receiving unit 2 can be implemented in the form of a smart watch, a bracelet, etc.
