Through long-term observation and research, the inventor finds that when the charging cover plate of the plate link chain runs below the pit, if the charging cover plate is opened, the charging cover plate is difficult to find timely and can collide with the steel structure, so that the charging cover plate is damaged. In view of this, the present utility model provides a detection device for a plate link chain apparatus that can detect a state in which a cover plate is not closed (has been opened or is being opened) by a sensor and determine a corresponding abnormal position. In the present utility model, the sensor may include one or more types of sensing modules, such as an infrared sensing module, a laser sensing module, an ultrasonic sensing module, and an image sensing module.

It should be noted that, in the following, the technical solution of the present utility model will be mainly described by taking a plate link chain and a cover plate as examples, however, it is understood that the technical solution of the present utility model may also be used in other situations where abnormality detection is required. In addition, although the detection is performed by taking the opening and closing state of the cover plate as an example, the technical scheme of the utility model can be used in other similar scenes.

Fig. 2 is a schematic diagram of a cover plate detecting device according to the present utility model.

The cover plate detection device comprises a transmission unit 101, a processing unit 102, an interaction unit 103 and a sensing unit 104, wherein the sensing unit 104 comprises a plurality of sensors S1 and S2 … … SN. In this embodiment, the plurality of sensors are distributed under the plate link chain and along the periphery of the plate link chain, and the sensing unit 104 generates alarm information when the sensors detect that the cover plate of the plate link chain is not closed or foreign matter is attached to the cover plate (affecting the operation of the plate link chain).

Specifically, at least a part of the plurality of sensors is in communication connection with the transmission unit 101, and the transmission unit 101 acquires alarm information from the sensor unit 104, from which it can be determined which sensor detected the abnormality. In other words, the alarm information may contain identification information of the relevant sensor. The processing unit 102 is coupled to the transmission unit 101 and is configured to generate cover plate status information based on the alarm information, wherein the cover plate status information characterizes at least the position of the cover plate in an abnormal state. The interaction unit 103 is configured to display the status of the cover in a text or image manner based on the cover status information, and is also configured to receive an input of a user. In an embodiment, the interaction unit 103 is configured to display corresponding text information and/or image information based on the alarm information, and a user can check the position of the failed cover plate through the interaction unit 103, locate errors more quickly, and control the operation of the link chain device. In an embodiment the interaction unit is a touch screen.

The processing unit 104 is further configured to stop the operation of the plate link chain in response to the alarm information, and when the corresponding malfunction is eliminated, the processing unit 104 may start the plate link chain by itself or based on an instruction input by the user through the interaction unit 103.

Fig. 3A to 3C show schematic views of sensors distributed according to an embodiment of the present utility model.

As shown in fig. 3A, a plurality of sensors S1 to S12 are distributed under the plate link chain 1, and the sensors are symmetrically distributed on both sides of the cover plate. It will be appreciated that, depending on the requirements of the application, the sensors and the transmission unit 101 may communicate wirelessly (e.g. Wi-Fi, bluetooth, zigBee or other wireless communication protocol), or may communicate by wire.

In the present embodiment, the sensors S1-S12 are configured as 6 sensor groups, and a signal transmission path is formed between each sensor group, for example, the sensors S3 and S4 construct a transmission path in the direction of a dotted line, and exchange data, for example, the sensors S3 and S4 send data to each other or one is used for sending data and the other is used for receiving data. When the cover is not closed, signal transmission within the sensor group (i.e. signal transmission between S3 and S4) will be disturbed, at which point the sensors S3 and/or S4 will issue an alarm message, and the alarm message contains at least the sensor identification in the sensor group.

It will be appreciated that the sensors may provide alarm information directly to the transmission unit 101, or that the sensing unit 104 may further comprise an interface module (not shown) for collecting alarm information from the respective sensors and providing the collected alarm information to the transmission unit 101.

Taking the sensors S3-S4 as an example, as shown in fig. 3B, when the signal transmission path between the sensors S3-S4 is interrupted by an obstacle (hatched portion), the sensing unit 104 will issue alarm information, and the alarm information includes at least identification information indicating the sensors S3, S4. Further, the alarm information may further include interference indication information indicating the degree of interference of the signal transmission path between the sensors S3, S4.

As shown in fig. 3C, the left side obstruction does not completely block the signal transmission path between the sensors S3-S4, as compared to the right side obstruction (equivalent to the cover not being closed). It is understood that although the signal transmission path is not completely blocked by an obstruction, the signal strength or signal integrity may be affected. In this way, it is possible to more accurately determine whether the operation of the link chain 1 needs to be stopped or not by the interference indication information. In an embodiment, the plate link chain 1 will continue to run when the obstacle is insufficient to affect the normal operation of the plate link chain 1.

The transmission unit 101 provides the alarm information to the processing unit 102, and generates cover plate state information based on the alarm information, wherein the cover plate state information at least characterizes the position of the cover plate in an abnormal state. As can be seen from the foregoing, the alarm information includes identification information indicating the sensors S3, S4. As shown in fig. 3D, in the provided graphical interface of the interaction unit 103, it can be directly observed that the sensors S3, S4 arranged at the plate link chain 1 generate alarm information. It will be appreciated that the interaction unit 103 may also present the working conditions of a plurality of plate links and may display corresponding text information and/or image information based on the alarm information. For example, the user can view on the graphical interface provided by the interaction unit 103 that there is a fault at the sensors S3-S4 that needs to be immediately removed, while the fault at the sensors S5-S6 does not need to be immediately removed, on the plate link chain 1. In addition, the user can select the plate link chain 2 or the plate link chain 3 on the graphical interface, so that the working conditions of the two plate links can be checked. When the sensor generates alarm information, the content contained in the alarm information is adaptively presented on the graphical interface, for example, the alarm information is presented graphically, the system reset information is presented in characters, and the like. From the above, the user can not only check the position of the cover plate with fault through the graphic interface and locate the error more quickly, but also control the operation of the plate link chain device.

FIG. 3E is a schematic diagram of a sensor distribution according to another embodiment of the present utility model.

Under the plate link chain 1, the sensors S1-S10 are distributed on both sides of the cover plate in a staggered manner, and adjacent sensors form a signal transmission path across the plate link chain. In comparison with the sensor distribution in fig. 3A, a signal transmission path is also formed between the sensors S2, S3 in fig. 3E. It will be appreciated that when the signal transmission path between the sensors S1, S2, or between the sensors S2, S3 is disturbed, the sensor unit 104 will issue an alarm message, and the alarm message contains at least the corresponding sensor identification.

Fig. 4A is a schematic diagram of sensor distribution according to another embodiment of the utility model, and fig. 4B is a schematic diagram of a detection principle of the sensor in fig. 4A.

In this embodiment, each sensor has a detection range. Referring to fig. 4B, the sensor S3 emits a detection signal JC, and when the detection signal JC propagates from the sensor S3 to an obstacle, a reflected signal FB is generated. In the present embodiment, the time T1 when the sensor S3 acquires the reflected signal FB can be expressed as: t1=t _JC +t _FB Wherein t is _JC To detect the time of propagation of the signal JC from the sensor S3 to the obstacle, t _FB To detect the time at which the signal JC is reflected from an obstacle to the sensor S3.

It will be appreciated that although the sensors are staggered on both sides of the plate link chain 1 in fig. 4A, in other embodiments, the sensors may be symmetrically distributed on both sides of the plate link chain 1 as shown in fig. 3A, or on one side of the plate link chain 1.

Referring again to fig. 4A, assume that the width of the plate link chain 1 is d. When there is an obstacle on the link chain 1, the sensor S3 emits and receives the reflected signal FB for a maximum period t2=2d/v, where v is the transmission speed of the detection signal JC. When the detection signal JC emitted by the sensor S3 is ultrasonic, v is 340m/S. Therefore, when the time T1 at which the sensor S3 acquires the reflected signal FB is equal to or less than T2, it can be determined that there is an obstacle on the plate link chain 1.

As described above, when there is an obstacle on the link chain 1, the user can view the position of the failed cover plate through the graphic interface provided by the interaction unit 103, locate the error more quickly, and control the operation of the link chain device.

In the present embodiment, the sensor S3 has an image capturing capability. The sensors S1-S5 monitor the space under the plate link chain 1 in real time or intermittently as the plate link chain 1 is operating normally. Taking the sensor S3 as an example, when it recognizes that there is an obstacle below the plate link chain 1 (the cover plate is not closed), the sensor S3 will send out alarm information, and the alarm information at least contains the identification of the sensor S3. It will be appreciated that in this embodiment, the sensors S1-S5 are distributed beneath the plate link chain, and that the field of view of the 5 sensors may cover the range of detection required.

The utility model also provides an embodiment, wherein the sensor is only responsible for capturing images, and judges whether an obstacle exists or not to be processed by a server (such as a processing unit). In other words, the sensor is used to generate operating condition information indicating the operating condition of the charging cover plate under the plate link chain, the transmission unit 101 supplies the operating condition information to the processing unit 104, and the processing unit 104 determines whether to generate cover plate abnormality information according to the operating condition information. Here, the cover plate abnormality information characterizes at least the position of the cover plate in an abnormal state.

Still taking fig. 5 as an example, the sensors S1-S5 continuously send the captured image signals to the processing unit, and when the image signal provided by the sensor S3 is determined by the processing unit 104 that an obstacle is present on the plate link chain 1, the processing unit 104 sends alarm information containing at least the identification of the sensor S3 to the interaction unit 103. By the identification of the sensor S3, the position of the cover plate in an abnormal state can be determined.

It will be appreciated by those skilled in the art that although the detection modes of the sensors in the above embodiments are different, in other embodiments, one sensor may have multiple detection modes, for example, the sensor may have both laser detection and ultrasonic detection functions. In another embodiment, multiple types of sensors may be used in combination.
