The upper part of the identification device 2 is fixedly connected to the suspension rod 1. The upper end of the load rod 3 is inserted from the bottom of the identification device 2 and connected with the identification device. The device 2 is elastically telescopically connected, so that the upper end of the load rod 3 can move up and down on the identification device 2; a conductive piece 7 is provided on the outer wall of the upper end of the load rod 3, and two cuts of an induction circuit of the induction chip 4 carried by the identification device 2 The point extends into the insertion cavity of the load rod 3, and the two cut-off points are aligned with the conductive member 7; when the upper end of the load rod 3 and the conductive member 7 are displaced downward, the conductive member 7 can connect with the two cut-off points. The contact is conducted, thereby conducting the sensing loop of the sensing chip 4 .

It should be clear that the upper part of the identification device 2 is fixedly connected to the lower end of the boom 1, and the upper end of the boom 1 can be provided with a mounting structure to be mounted on the production suspension line for operation; the upper end of the load bar 3 is connected to the identification device 2 There is an elastic telescopic connection between them, and the lower end of the load rod 3 is provided with a support structure for hanging garments. It can be understood that the mounting structure can be a hook, and the support structure can be a conventional triangular support structure. The identification device 2, the boom 1, and the load bar 3 can form a hanging vehicle and run on the production hanging line.

In this application, the induction chip 4 includes at least two induction loops, and one of the induction loops is cut off, and the two cutoff points formed are connected through the conductive member 7 . The position change of the load rod 3 is limited by the attachment structure of the conductive member 7, if and only if there is a load on the load rod 3, and the weight of the load pulls down the load rod 3 so that the conductive member 7 is in alignment contact with the two cut-off points. , the two cutoff points can be connected, thus forming a complete induction loop.

Further, when the truncated induction loop is turned on, the induction chip 4 can be excited to emit the second excitation data. The uninterrupted induction loop is always in a conductive state and can excite the induction chip 4 to emit the first excitation data.

In the embodiment of the present application, a load-bearing plate 23 is provided at the bottom of the identification device 2, and an insertion cavity is provided for inserting the load rod 3. The load-bearing plate 23 is aligned with a through hole connected to the insertion cavity, so that the load rod 3 can pass through the through hole. The hole is inserted into the insertion cavity to complete the elastic telescopic connection with the identification device 2; the load rod 3 inserted into the identification device 2 is provided with a conductive piece 7. When the load rod 3 is displaced downward, the two cutoff points pass through the load rod 3 The conductive member 7 performs conduction.

Specifically, the insertion cavity includes a telescopic cavity 21 and a conductive cavity 22. The telescopic cavity 21 is opened directly above the through hole, and the conductive cavity 22 is opened upward from the top center of the telescopic cavity 21 so that the upper end of the load rod 3 can pass through. The through hole directly passes through the telescopic cavity 21 and is inserted into the conductive cavity 22 .

The load rod 3 is located in the telescopic cavity 21 and is provided with a limit ring 32. The diameter of the limit ring 32 is larger than that of the conductive cavity 22. A spring 8 is set on the load rod 3 between the limit ring 32 and the load plate 23. The spring 8 is The diameter is larger than the through hole, thus forming an elastic telescopic connection. It can be understood that when the load rod 3 moves up and down along the axis, it is limited upward by the contact between the limit ring 32 and the top wall of the telescopic cavity 21 , and downward by the limit ring 32 to compress the spring 8 to the limit state. It contacts the bearing plate 23 to limit the position.

When the lower end of the load rod 3 is loaded with heavy objects, gravity support is provided by the load-bearing plate 23. Therefore, the structural stability of the load-bearing plate 23 can be optimized according to actual needs and its bearing capacity can be increased to meet the load weight requirements.

In a specific embodiment, a base column 31 can be coaxially disposed on the top of the load rod 3. The base column 31 is always located in the conduction cavity 22. The conduction member 7 is disposed on the outer wall of the base column 31 along the axial direction. The component 7 includes an upper contact 71, a lower contact 72, and a connecting portion 73 that connects the upper contact 71 and the lower contact 72. The upper contact 71 and the lower contact 72 are respectively provided at both ends of the connecting portion 73. .

Specifically, one end of the upper contact member 71 and the lower contact member 72 is fixedly connected to the connecting portion 73, and the other end elastically contacts the inner wall of the conductive cavity 22.

Correspondingly, the first contact ring 5 and the second contact ring 6 are embedded in the inner wall of the conduction cavity 22 along the axial direction. The first contact ring 5 and the second contact ring 6 are insulated and isolated, and the first contact ring 5 and the second contact ring 6 are insulated. The second contact ring 6 is axially aligned with the upper contact member 71 and the lower contact member 72, and the two cutoff points of the induction circuit are connected to the first contact ring 5 and the second contact ring 6 respectively. The upper contact 71 and the lower contact 72 are in elastic contact with the inner wall of the conduction cavity 22, so that the upper contact 71 and the lower contact 72 can be in contact with the first contact ring 5 and the second contact ring 6 respectively, so that The two cutoff points of the induction loop are connected to meet the basic conditions for generating the second excitation data.

It can be understood that the upper contact 71 and the lower contact 72 are elastic contacts with an annular structure, and the direction of elastic force between them and the circumferentially arranged first contact ring 5 and second contact ring 6 is as shown in Figure 5 shown; the connecting part 73 can be a fixed annular structure, and the upper contact 71 and the lower contact 72 can be provided with multiple elastic branches. The multiple elastic branches can be distributed in an annular shape so that they can match the elastic force of the contact ring in the circumferential direction. Basically consistent to avoid unstable contact and conduction.

Furthermore, the end of one end of the upper contact 71 and the lower contact 72 that are in elastic contact with the conductive cavity 22 can be extended to be suspended close to the outer surface of the base column 31, which is beneficial to maintaining/restoring the upper contact 71 and the lower contact. The elasticity of piece 72. The base pillar 31 and the conductive member 7 can be directly insulated, or the base pillar 31 can be made of insulating material.

In the embodiment of this application, the sensing chip 4 may be a passive electronic tag. The sensor is used to read the written data of the electronic tag. The written data includes first excitation data and second excitation data. It can be understood that the second excitation data can be a string with no substantial meaning, and it is only necessary to detect the presence or absence; if necessary, the second excitation data can be set to a fixed string to avoid external interference.

In a specific embodiment, please refer to Figure 6. The sensing chip 4 includes a chip 41, a first antenna 42, and a second antenna 43. The first antenna 42 can be cut off, and the two cutoff points can be extended to the conduction cavity. The inner wall of 22 is electrically connected to the first contact ring 5 and the second contact ring 6 respectively. The excitation signal of the first antenna 42 is used as the second excitation data, and the excitation signal of the second antenna 43 is used as the first excitation data.

In a specific embodiment, the sensing chip 4 may include two independent passive mat tags, one of which is cut off to form two cutoff points.

In the embodiment of the present application, an internal ring 33 is provided on the lower side of the limiting ring 32. The upper end of the spring 8 set is sleeved on the internal ring 33, and the lower end of the spring 8 abuts against the bearing plate 23. The length of the internal ring 33 is slightly shorter than the compression limit length of the spring 8, and the diameter of the internal ring 33 is slightly smaller than the inner diameter of the spring 8, so that the spring 8 is less likely to produce abnormal deformation when compressed.

Embodiment 2 This application also proposes a control method for an identification device of a suspended carrier, which is suitable for the identification device in Embodiment 1, specifically including:
Receive and detect the induction data excited by the identification device, and determine the load status of the vehicle corresponding to the identification device;
When it is detected that the sensing data includes first excitation data and second excitation data, load information is sent, and the carrier is in a load state;
When it is detected that the sensing data only includes the first excitation data, send no-load information, and the carrier is in an no-load state;
Record the sensing data of the identification device and associate it with the corresponding carrier.

The execution subject of this application can be a hanging vehicle, sensor and monitoring platform equipped with an induction chip. The hanging vehicle runs on the hanging production line and cooperates with the sensor at the corresponding position to stimulate the signal. Through the induction chip The transmitted data is used to determine the operating status of the vehicle.

The sensor is used to stimulate the sensing chip to emit signals, and the signals emitted by the sensing chip are received, which is defined as sensing data. Different from conventional sensor chips, the amount of sensing data emitted by the sensor chip of the present application is related to whether the carrier is carrying clothes. Therefore, the operating status of the carrier can be judged by detecting the sensing data.

Specifically, the sensing data includes first excitation data and second excitation data. The first excitation data is normal excitation, which is generated by the uninterrupted induction loop in the sensing chip; the second excitation data is load excitation, which is generated by the sensing chip. The truncated induction loop is excited.

When the vehicle is unloaded, the truncated induction loop is in an open circuit state and cannot generate second excitation data.

When the vehicle is loaded, the truncated induction loop is in a conductive state and can generate second excitation data.

Therefore, for a running vehicle, when the sensor detects that the sensing data includes the first excitation data and the second excitation data, it means that the vehicle is in a load state, and load information can be sent to the monitoring platform to reflect the current The state of the vehicle; when the sensor detects that the sensing data only includes the first excitation data, it means that the vehicle is in an unloaded state, and no-load information can be sent to the monitoring platform to reflect the current state of the vehicle.

It is understandable that by only detecting the real-time status of the current vehicle, it is impossible to know whether the clothes carried on the vehicle are decoupled. Therefore, the historical sensing data of the current vehicle should also be called to determine whether the operating status of the vehicle is changes, and then determine whether there is decoupling of clothing.

In the embodiment of the present application, the specific steps of monitoring the operating status of the vehicle include:
Query the historical sensing data of the vehicle and determine whether the second excitation data is resident:
If the second excitation data is resident and the current sensing data does not include the second excitation data, the items carried by the hanging vehicle will fall, the falling interval will be marked, and an alarm message will be sent;
If the second excitation data is resident and the current sensing data includes the second excitation data, the hanging vehicle is in a load state;
If the second excitation data does not exist in the historical sensing data, and the current sensing data does not include the second excitation data, then the hanging vehicle is in an unloaded state;
If the second excitation data does not exist in the historical sensing data and the current sensing data includes the second excitation data, then the hanging vehicle is in a load state and the upload interval is marked.

When judging whether the second excitation data is resident, a continuous value can be predefined. When there are multiple sensors that detect the second excitation data, and the number exceeds the continuous value, it is considered that the second excitation of the vehicle is present. The data is resident and its operating status is stable in load status. It can be understood that the setting position of the sensor is often in the node area, and the operation of the vehicle is relatively stable, and no large jitter is generated to make the circuit conduction of the sensor chip unstable, and there is no floating second excitation data. If this phenomenon occurs, an error can be reported to the monitoring platform; therefore, its resident judgment is valid when there is no fault in the sensing chip. If the sensor chip fails, effective judgment cannot be made.

In the same way, it can be seen that when there are multiple sensors detecting the second excitation data and all the results are that it does not exist, and the number exceeds the continuous value, it is considered that the second excitation data of the vehicle does not exist, and its operating status is stable as no-load state. .

In this application, when the second excitation data is resident, it means that the historical state of the vehicle is the load state. If the current sensing data does not include the second excitation data, it means that the current state of the vehicle is the unloaded state, and the state changes. , if the items loaded on it fall, the corresponding drop interval can be marked and an alarm message can be sent; if the current sensing data includes the second excitation data, it means that the current state of the vehicle is the load state and the operating state is normal. If necessary, the removal section can be marked and the removal of the vehicle can be detected through sensors in the removal section.

In this application, when the second excitation data does not exist, it means that the historical state of the vehicle is an unloaded state. If the current sensing data does not include the second excitation data, it means that the current state of the vehicle is an unloaded state, and the state is not. A change occurs; if the current sensing data includes the second excitation data, it means that the current state of the vehicle is the load state, the state has changed, and the corresponding items are loaded on the vehicle, and the corresponding upload interval can be marked.

It is understandable that marking the falling interval can quickly determine the falling location and carry out maintenance and recovery. Mark the upload interval to indicate the mounting starting point of the vehicle.
