When the sensing device 120 detects that the real-time distance between the two markers 110 exceeds the set distance, it can be determined that the tensile deformation of the transmission belt between the two markers 110 has exceeded the critical point, i.e., a fracture or partial fracture is about to occur or has occurred.

The processor 130 can compare the sensed distance with the set distance to determine whether the sensed distance exceeds the set distance.
When the processor 130 determines that the sensing distance exceeds the set distance, it indicates that the joint between the two identification members 110 is abnormal, and at this time, the processor 130 may send a prompt message to prompt a person to perform exception handling.
Specifically, in some embodiments, the joint detection mechanism 100 further includes an alarm device 140, and the alarm device 140 may be coupled to the processor 130.

Referring to fig. 3, fig. 3 is a schematic view of the installation positions of the identifier and the sensing device in another embodiment of the joint detection mechanism shown in fig. 1.
In this embodiment, the identification member 110 may be a long strip, and the long side direction of the long strip of the identification member 110 may be parallel to the width direction of the transmission belt. The elongated identification member 110 may be made of a flexible material. When the joint of the transmission belt between the two identification members 110 is partially cracked, the elongated identification member 110 corresponding to the cracked position of the transmission belt may be bent along with the transmission belt, and at this time, the interval between the partial areas of the two elongated identification members 110 may also be changed.
In the above-described embodiments, the identification member 110 may be embedded in the conveying belt, or the identification member 110 may be a protrusion portion provided on the conveying belt.
In some embodiments, the identification member 110 is a magnetic member when the identification member 110 can be embedded in the transmission belt. The sensing device 120 may be a hall sensor.
The identification member 110 may be a magnetic card, each magnetic card may have individual identification information, and each magnetic card may maintain position information of the magnetic card mounted on the conveyor belt. In this embodiment, two magnetic cards (or two rows of magnetic cards) may also be respectively installed on two opposite sides of the connector, and the magnetic cards may be identified and detected by using a Radio Frequency IDentification (RFID) technology, so as to obtain identity information of each magnetic card and position information of each magnetic card on the transmission belt.

In another aspect of the present application, a method for detecting a splice is also provided. Referring to fig. 4, fig. 4 is a schematic flowchart illustrating an embodiment of a joint detection method according to the present application. In this embodiment, the joint detection method may specifically include the following steps:
s110: the actual spacing at the two ends of the joint is obtained.
In this step, the identifier may be respectively disposed on two opposite sides of the joint in the manner as described above, and the distance between the identifiers disposed on two opposite sides of the joint may be detected, so that the actual distance between two ends of the joint may be obtained, and the actual distance may be equal to the sensing distance as described above.
Wherein the markers on opposite sides of the joint may have a set spacing.
S120: and comparing the actual distance with the set distance.
After the actual spacing at the two ends of the joint is obtained in step S110, the actual spacing may be compared with the set spacing. Wherein the set pitch is the distance between the ends of the joint of the qualified conveyor belt in the normal state. It will be understood that the set pitch is the distance between any two points on the joint in the transport direction, i.e. the distance between the two markers. And, in theory, the distance between the two identification members should always be a set spacing as long as the conveyor belt is not torn.
S130: and if the actual distance exceeds the set distance, judging that the joint is abnormal.
In this step, when it is determined that the actual distance exceeds the set distance, it is determined that an abnormality occurs at the joint. Specifically, when the actual distance between the ends of the joint exceeds the set distance, it is possible to indicate that the joint is elongated and that a fracture or a partial fracture occurs in the joint.
In some embodiments, if the connector is judged to be abnormal, an alarm message can be sent out. For example, alarm information can be sent to a corresponding alarm device, such as an alarm display lamp or an alarm sounding device, so that the alarm device can give an alarm prompt, and personnel can be notified to perform troubleshooting or exception handling.
Or alarm information can be sent to a corresponding remote terminal.
In some embodiments, the step S130 may specifically include determining whether the actual distance is greater than the set distance, or determining whether the actual distance exceeds a range of the set distance. Specifically, in some embodiments, the set pitch may be a fixed value, and the actual pitch may be compared with the set pitch, and when the actual pitch is greater than the set pitch, it indicates that the actual pitch exceeds the set pitch. Generally, because there is an allowable error or because the transmission belt has a certain stretching elasticity, there is no tearing problem in a certain stretching range, therefore, in some other embodiments, the set pitch may also be a pitch range, and if the actual pitch is not within the pitch range, it indicates that the actual pitch exceeds the set pitch. When the actual distance is judged to exceed the set distance through any one of the two schemes, the abnormality at the joint can be judged.
Further, in some other embodiments, the method for detecting a linker further comprises: and displaying the judgment result. Specifically, when it is determined that the actual pitch exceeds the set pitch, the display device may display information on the joint in which the abnormality has occurred. For example, a number, position information, etc. corresponding to the joint may be displayed; or the color of the icon corresponding to the abnormal joint can be changed or the icon corresponding to the abnormal joint can be displayed by flashing. It is understood that when it is determined that the actual spacing does not exceed the set spacing, information that the joint is normal may also be displayed.

Wherein, two identification components 110 set up the relative both sides at the joint of transmission band respectively, when the joint on the transmission band passes through induction system 120 along with the motion of transmission band gradually, then induction system 120 can detect the interval between two identification components 110 of this joint relative both sides to acquire the sensing interval between two identification components 110. The processor 130 may compare and analyze the sensing distance and the set distance between the two identification members 110, and when the sensing distance between the two identification members 110 exceeds the set distance, it may indicate that the joint position is abnormal.
When the transmission belt has a plurality of joints, the positions of two opposite sides of each joint can be respectively provided with one identification member 110. And the sensing components formed by the two identifiers 110 corresponding to each joint can be numbered, and the joint corresponding to each sensing component can be positioned through the number of the sensing component by binding the position information of each group of sensing components on the transmission belt with the number.

When the sensing device 120 detects that the sensing distance between the two identifiers 110 in any group of sensing assemblies exceeds the set distance, the sensing device 120 can send out prompt information. Because the plurality of groups of sensing assemblies are respectively numbered and positioned, the number information of the group of sensing assemblies can be further included in the transmitted prompt information, the abnormal position of the transmission belt can be rapidly determined, so that personnel can rapidly position the abnormal position of the transmission belt, and the processing efficiency of the abnormity of the transmission belt can be further improved.

The display device 250 may be the same as the display device 150 described above. Alternatively, both are the same display device.
The display device 250 may display the operation condition of the transmission belt, for example, the operation speed, the operation time, and the like of the transmission belt.
When the sensing device 120 detects that the real-time distance between two identifiers 110 in any identifier 110 exceeds the set distance or detects that the real-time distance exceeds the sum of the set distance and the stretching threshold, the sensing device 120 may send a prompt message, and at this time, the control device 230 may control the display device 250 to display the number positioning information of the identifier 110 with the corresponding abnormality according to the prompt message.
