On 1 until 3 is referred to. 1 Fig. 12 shows a flow chart of the safety check method for the box-shaped hoist system of a wind turbine of the embodiment of the invention. As in 1 shown, the invention includes the following steps:

• Step 1: Before each operation of the elevator system, a decision is made based on the comparison of the current raising and lowering rate of the elevator system with the specified threshold value as to whether the elevator system needs to be checked. If the current raising and lowering count exceeds the threshold, the safety check circuitry of the elevator system is shut down. After the security check circuit is manually turned on, the rise and fall count returns to zero;

In step 1, the number of times the elevator installation can be raised and lowered is determined by a threshold value. Based on the count threshold, the security check circuit limits the working count of the elevator system. After the safety check circuit has been switched off, the elevator system cannot be started. Several switches on the security check circuit must be manually operated to continue operation.

Step 2: Obtaining the image information outside the elevator system, extracting the characteristic image information parameters of wearing the protective equipment correctly, performing part feature recognition on the image information by the trained parts monitoring model, to judge whether the user is wearing the protective equipment correctly.

In step 2, the training process of the parts monitoring model includes: A plurality of first sample portrait images with a properly worn helmet, second sample portrait images with an improperly worn helmet, third sample portrait images with properly worn climbing protection equipment, and fourth sample portrait images with incorrectly worn climbing protection equipment are obtained. Using Mosaic's data enhancement method in YOLOv4, a specific Number of sample images combined into one training image. The synthesized first sample portrait training image and second sample portrait training image are respectively input to the first training data set and the first test data set with the ratio of 5:1, thereby obtaining the first recognition model. The synthesized third sample portrait training image and the fourth sample portrait training image are input to the second training data set and the second test data set with the ratio of 5:1, thereby obtaining a second recognition model.

It should be noted that in order to avoid misjudgment, the system uses the binding and matching method. "Head with helmet" and "head without helmet", "body with protective equipment" and "body without protective equipment" can be used as two different monitoring targets, which can effectively prevent the occurrence of misjudgment.

Step 3: Output alarm information; Advance warning on the one hand via the external terminal for the failure of the elevator system and reproduction of the voice information on the other hand via the voice information module for the reason for the failure of the elevator system.

In step 3, the information output from the voice prompt module is the detection result of the safety verification circuit and the parts monitoring model, such as: helmet worn incorrectly, helmet not worn, anti-climbing equipment incorrectly worn, anti-climbing equipment not worn, please check the elevator equipment, please check a component, etc.

In the above structure, the controller may be a controller having a data processing function, such as a prior art one-chip microcomputer. However, the present invention is not limited to this and other suitable types of controllers are also possible. The controller receives the lifting and lowering number of the elevator system via the counting module. When the hoisting and lowering rate of the elevator system reaches the threshold range of the hoisting and lowering rate, it means that inspection of several parts of the elevator system is required. In this case, several contact switches are opened by the control switch module so that the elevator system can no longer be used.

The two work together to output the on-off signal of the contact switch to the control switch module through the capacitance change by sensing the finger touching the surface of the switch and the pressure applied to the switch. The control switch module receives the signals of each contact switch, including the signals of the capacitive flexible contact circuit film and the pressure sensor, and performs logical judgment processing. The outer surface of the contact switch is further provided with an LED indicator lamp to indicate the status of the contact switch by the light signal.

In the above structure, the image information of the person outside the elevator system is captured by the camera, and the image information is uploaded to the system controller. The controller uses existing artificial intelligence technology to detect whether the user is wearing protective gear. When the protective equipment is worn correctly, a command is sent to open the elevator system door. If the user does not wear protective equipment, the elevator system cannot be used.

Furthermore, the image recording device has a voice instruction module. The voice hint module is used to output voice information of the recognition results of the first recognition model and the second recognition model.

In the above structure, the voice hint module pre-uses an existing voice reproduction device. The voice playback device is used to read the recognition results of the first recognition model and the second recognition model and play them back.
