[0074] The working process of the blind plate state detecting device will be described in detail below. Figure 1 -4, as Figure 6 -10, and the working process of the blind plate state detecting device will be described in detail below.

[0075] In one embodiment, when the blind plate 4 is in the in-place state, i.e., the blind plate 4 is clamped between the flanges 33, the first rotating part 26 of the detecting claw 23 is driven by the clamping of the flanges 33 to rotate towards the blind plate 4 until it closely abuts the blind plate 4, the rotation of the first rotating part 26 drives the rotation of the second rotating part 27, the second rotating part 27 generates a pushing force on the detecting shaft 142 of the transmission mechanism 14, pushing the detecting shaft 142 to move towards the detecting element 13 until it abuts the detecting element 13, triggering the detecting element 13, the detecting element 13 generates a trigger signal and transmits it to the main control module 12, the main control module 12 receives the trigger signal, judges that the blind plate 4 is in the in-place state, and then sends this state to the communication base station through the antenna 19.

[0076] When the blind plate 4 is not in the in-place state, i.e., the blind plate 4 is not clamped between the flanges 33, the first rotating part 26 is in a separated state from the blind plate 4, and the second rotating part 27 is also in a separated state from the detecting shaft 142, since the gasket 144 on the detecting shaft 142 generates a pressing force on the elastic member 143 when it moves towards the detecting element 13, the elastic member 143 generates an elastic force, and the detecting shaft 142 is reset due to the elastic force of the elastic member 143 when it is not pushed by the second rotating part 27, and is disconnected from the detecting element 13, the detecting element 13 does not receive the trigger signal, and the main control module 12 does not receive the trigger signal, and then judges that the blind plate 4 is not in the in-place state, and sends this state to the communication base station through the antenna 19.

[0077] In another embodiment, the second rotating part 27 of the detecting claw 23 is provided with a magnetic element, and the detecting element 13 is an inductive element.

[0078] When the blind plate 4 is in the in-place state, i.e. the blind plate 4 is clamped between the flanges 33, the first rotating part 26 of the detection claw 23 is driven by the clamping of the flanges 33 to rotate towards the blind plate 4 until it is tightly attached to the blind plate 4. The rotation of the first rotating part 26 drives the rotation of the second rotating part 27, which rotates towards the detection element 13. The detection element 13 senses the change of the magnetic field, generates an induction signal and transmits it to the main control module 12. The main control module 12 receives the induction signal and judges that the blind plate 4 is in the in-place state, and then sends the state to the communication base station through the antenna 19.

[0079] When the blind plate 4 is not in the in-place state, i.e. the blind plate 4 is not clamped between the flanges 33, the first rotating part 26 is separated from the blind plate 4, and the second rotating part 27 is away from the first rotating part 26 due to the rotation of the first rotating part 26. The detection element 13 senses a weak magnetic field or no magnetic field, and thus does not send an induction signal to the main control module 12. The main control module 12 does not receive the induction signal, judges that the blind plate 4 is not in the in-place state, and then sends the state to the communication base station through the antenna 19.

[0080] In an embodiment, a coil box with a coil 31 is arranged in the detection unit 1. The coil 31 is connected to the main control module 12 in the detection unit 1 and sends the flange identity to the main control module 12. The coil box can be arranged near the bottom of the shell 11 of the detection unit 1 and corresponds to the flange identification module 32.

[0081] The blind plate state detection device further comprises a flange identification module 32, which is fixedly connected to the flange 33 and comprises a code sheet 34 arranged at a position corresponding to the coil box. The code sheet 34 stores the flange identity and is wirelessly coupled to the coil 31. The main control module 12 can read the code through wireless matching of the coil 31 and the code sheet 34, and monitor and judge through the anti-misoperation system to confirm whether the blind plate 4 and the flange 33 match. The main control module 12 controls the indicator light 191 of the detection unit 1 to keep constant or flicker according to the flange identity sent by the coil 31 to provide information.

[0082] Specifically, when the blind plate 4 is installed between the flanges 33, the coil 31 of the detection unit 1 corresponds to the code sheet 34, the coil 31 and the code sheet 34 are wirelessly matched, the flange identity is sent to the main control module 12, and the main control module 12 judges whether the flange identity of the flange 33 matches the code of the blind plate 4 and controls the indicator light 191 to operate accordingly.

[0083] If they match, the indicator light 191 is kept constant to prompt the user; if they do not match, the indicator light 191 flickers to prompt the user.

[0084] The embodiment of the present application can monitor the position state of the blind plate 4 in real time by setting the anti-misoperation system and cooperating with the coil and the flange identification module, record data in the operation process of the blind plate state detection device, and quickly respond and timely prompt the user when problems occur, thereby improving the work efficiency, simplifying the program steps, and improving the user experience.

[0085] In an embodiment, the indicator 191 is further used to indicate whether the detection unit 1 is activated, when the detection element 13 is triggered and the detection unit 1 is activated, the indicator 191 is controlled to be turned on, and when the detection element 13 is not triggered and the detection unit 1 is still in a dormant state, the indicator 191 is controlled to remain off.
