Further, the optical transmission sensor device 60 includes a plug fixing sleeve 10, a limiting component 20, a magnetic unit 30 and an optical transmission member 40, both ends of the plug fixing sleeve 10 are open, and the plug fixing sleeve 10 is suitable for being fixedly connected with the mounting seat 80 of the to-be-detected member; the limiting assembly 20 is arranged in the plug fixing sleeve 10; the magnetic unit 30 is detachably arranged at one end of the plug fixing sleeve 10 and is abutted against the limiting component 20, the magnetic unit 30 is suitable for being magnetically connected with the to-be-detected piece 70, and a light reflecting piece 310 is fixedly arranged on one side of the magnetic unit 30, which faces the limiting component 20; the optical transmission member 40 is further included, and the optical transmission member 40 sequentially penetrates through the plug fixing sleeve 10 and the limiting assembly 20 and is arranged opposite to the optical reflection member 310 so as to transmit optical signal information related to the relative position of the to-be-detected member 70 and the to-be-detected member mounting seat 80. The bottom of the member 70 to be detected is provided with a magnet material capable of magnetically attracting the magnetic unit 30. Furthermore, the plug fixing sleeve 10 can be installed first, and then the magnetic unit 30 is sleeved in the plug fixing sleeve 10, so that when the piece to be detected 70 is matched with the piece to be detected mounting seat 80, the magnetic unit 30 can always keep the light reflection piece 310 corresponding to the light transmission piece 40, and therefore, the detection efficiency and accuracy can be improved. And a fixed mounting area does not need to be provided on the member to be detected 70, whereby the alignment correction time of the light reflecting member 310 and the light transmitting member 40 can be saved.

The position limiting assembly 20 includes a collar 210, a light transmission member plug 220 at least partially sleeved in the collar 210, and an elastic member 230 disposed on a side of the light transmission member plug 220 away from the collar 210; the magnetic unit 30 abuts against the collar 210, and the elastic member 230 abuts against the optical transmission member plug 220. That is, when the piece 70 to be detected and the piece mount pad 80 to be detected are installed in a matching manner, that is, the current piece 70 to be detected and the piece mount pad 80 to be detected are arranged at intervals and have a certain distance, and then the magnetic attraction unit 30 can slide along the plug fixing sleeve 10 for a certain distance, at this time, the magnetic attraction unit 30 and the optical transmission piece 40 are arranged at intervals and have a certain distance, and when the installation between the piece 70 to be detected and the piece mount pad 80 to be detected is completed, the magnetic attraction unit 30 can move towards the direction of the optical transmission piece plug 220, and therefore the magnetic attraction unit abuts against or approaches the optical transmission piece plug 220 to complete the installation. The elastic member 230 is disposed such that the collar 210 and the optical transmission plug 220 are in an elastic abutting state to improve the installation stability of the optical transmission plug 220, and the magnetic unit 30 can be elastically buffered during installation, so that the magnetic unit 30 is prevented from being damaged by pressure on the detection end of the optical transmission element 40. In one embodiment of the present invention, the magnetic unit 30 can be a magnet.

The ring 210 has a light transmitting member channel 2110 formed therein, and the light transmitting member 40 passes through the elastic member 230 and the light transmitting member channel 2110 and extends to an end of the light transmitting member plug 220 facing the light reflecting member 310. Further, at least one light transmission element limiting opening 2210 is formed on one side of the light transmission element plug 220 close to the magnetic unit 30, and the light transmission element 40 penetrates through the light transmission element limiting opening 2210. The light transmission member position limiting opening 2210 is configured to limit the position of the light transmission member 40. In one embodiment of the present invention, the number of the optical transmission members 40 is two, and two optical transmission member limiting openings 2210 are further formed on the collar 210. In other embodiments, the number of the optical transmission members 40 may also be one, for example, when a wire core simultaneously transmits and receives signals, the corresponding collar 210 is provided with one optical transmission member limiting opening 2210.

In an embodiment of the present invention, the optical transmission plug 220 is provided with a limiting step, and a circumferential dimension of the optical transmission plug 220 near the magnetic attraction unit 30 is smaller than a circumferential dimension of the optical transmission plug 220 far from the magnetic attraction unit 30. That is, a position-limiting surface is provided between the plugs 220 of the optical transmission element having a position-limiting step, and the position-limiting surface can abut against an end surface of the collar 210 far away from the magnetic unit 30. For example, when the magnetic unit 30 abuts against the collar 210, the bottom surface of the collar 210 abuts against the limiting surface, and further compresses the elastic member 230, so that under the action of the elastic member 230, the collar 210, the optical transmission member plug 220 and the magnetic unit 30 are in an elastic abutting state, and thus when the to-be-detected member 70 is separated from the to-be-detected member mounting seat 80, the collar 210 buffers the outward ejection force of the optical transmission member plug 220. In an embodiment of the invention, when the magnetic unit 30 is separated from the plug fixing sleeve 10, the elastic member 230 is restored from the compressed state, and when the friction force between the collar 210 and the plug fixing sleeve 10 is greater than the deformation force of the elastic member 230, the collar 210 acts as a limit function for the light transmission member plug 220, so as to prevent the collar 210 and the light transmission member plug 220 from being separated from the plug fixing sleeve 10.

One side of the plug fixing sleeve 10 is provided with an extending plate 110, the extending plate 110 is provided with at least one mounting hole 1110, and the extending plate 110 is fixedly connected with the mounting seat 80 of the to-be-detected piece through a bolt. It should be noted that, in an embodiment of the present invention, the protruding plate 110 and the to-be-detected object 70 are fixedly connected by bolts, and in other embodiments, welding or bonding may also be adopted, for example, the protruding plate 110 and the to-be-detected object mounting seat 80 may be welded or bonded for fixing, which is not limited herein.

Referring to fig. 7, fig. 7 is a flowchart illustrating a detection method using the sensing device shown in fig. 1. In an embodiment of the present invention, a detection method based on the above sensing monitoring system is further provided, including:

s110: transmitting a sequence of digital signals;

that is, the digital signal sequence is transmitted by the digital signal sequence generator, and the light emitting device converts the digital signal sequence into an optical signal and transmits the optical signal through the optical transmission member.

S120: receiving a digital signal sequence;

the light signal reflected by the light reflection piece is converted into a digital signal through the photosensitive device and the digital signal sequence detector, and the digital signal is compared with the emitted digital signal.

S130: and comparing the transmitting digital signal sequence with the receiving digital signal sequence to judge the optical signal information related to the relative position of the to-be-detected piece and the to-be-detected piece mounting seat.

If the detected received digital signal sequence is the same as the transmitted digital signal sequence, no displacement occurs between the piece to be detected and the mounting seat of the piece to be detected. And if the detected received digital signal sequence is different from the transmitted digital signal sequence, the piece to be detected is separated from the mounting frame of the piece to be detected.

In conclusion, the invention can determine the position information of the piece to be detected through the matching between the light transmission piece and the light reflection piece, so that the periphery of the piece to be detected is not provided with an electric connection piece, thereby improving the safety of the piece to be detected in the detection process. And through magnetism inhale the unit with wait to detect the piece and cooperate in order to guarantee to detect the piece and wait to detect a mount pad at the installation, the light reflection piece on the unit is inhaled all the time with light transmission piece and is in the alignment state, improves the accuracy that detects from this.
