Intelligent logistics lock with adsorption detection function

Abstract

This utility model relates to an intelligent logistics lock with adsorption detection function, including a lock body, a magnetic attraction device, a magnetic attraction status detection device, a main control circuit board, and a communication device for communicating with a remote monitoring party. The magnetic attraction device generates magnetic force to attract the lock body to the container. The magnetic attraction status detection device detects the adsorption status signal generated when the lock body is attracted to the container. The main control circuit board receives the adsorption status signal sent by the magnetic attraction status detection device. The magnetic attraction status detection device sends the adsorption status signal generated when the lock body is attracted to the container to the main control circuit board. After receiving the adsorption status signal, the main control circuit board determines that the intelligent logistics lock has been attracted to the container. If the intelligent logistics lock is forcibly separated from the container, the main control circuit board determines that the intelligent logistics lock has not been attracted to the container because it has not received the adsorption status signal, thus avoiding the situation where the actual status of the lock cannot be accurately monitored due to the steel cable being cut.

Description

Technical Field

[0001] This utility model relates to the field of logistics locks, and in particular to an intelligent logistics lock with adsorption detection function. Background Technology

[0002] Intelligent logistics locks, as a type of smart monitoring terminal widely used in modern logistics in-transit monitoring systems, integrate multiple functions in addition to traditional mechanical locks, including 4G communication, GPS positioning, anti-tamper alarm, wire rope cut alarm, unlocking / unsealing, remote monitoring, and charging. In use, the intelligent logistics lock is secured to the container by passing a wire rope through its lock hole, thus achieving real-time monitoring of the container. Currently, intelligent logistics locks are widely used in logistics transportation and customs clearance inspection.

[0003] However, existing smart logistics locks have shortcomings: since the logistics locks are tied to the containers by steel wire ropes passing through the container lock holes, once someone cuts through the container lock holes and removes the logistics lock, the remote monitoring party can still monitor that the logistics lock is in the locked state, but cannot monitor that the logistics lock has actually been removed from the container. This is not conducive to the remote monitoring party monitoring the container status based on the obtained logistics lock status. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an intelligent logistics lock with adsorption detection function that can avoid the inability to accurately monitor the actual status of the lock after the container lock hole is sawn off and the logistics lock is removed, in order to avoid the above-mentioned existing technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: an intelligent logistics lock with adsorption detection function, including a lock body, characterized in that it further includes:

[0006] The magnetic attraction device is configured to generate a magnetic force to attract the lock body to the container.

[0007] The magnetic attraction status detection device detects the attraction status signal generated when the lock body is attracted to the container.

[0008] The main control circuit board receives the adsorption status signal sent by the magnetic adsorption status detection device.

[0009] The communication device, connected to the main control circuit board, is configured to establish a communication connection with a remote monitoring party.

[0010] Improvedly, in the smart logistics lock, the magnetic attraction status detection device includes:

[0011] The elastic element abuts against the magnetic attraction device to produce elastic compression deformation when the lock body is attached to the container.

[0012] The adsorption detection circuit board is equipped with a linear Hall sensor, which generates a voltage signal based on the polarity and magnetic field strength of the magnetic attraction device; the adsorption detection circuit board is communicatively connected to the main control circuit board, and the voltage signal is the adsorption state signal.

[0013] Furthermore, in the intelligent logistics lock with adsorption detection function, the magnetic attraction device is a magnet, the magnetic attraction device is located in the lock body, and the elastic element is located in the space formed between the magnetic attraction device and the side wall of the lock body; wherein, the side wall is configured to be attracted to the container.

[0014] Further improvements include, in the intelligent logistics lock with adsorption detection function, the lock body comprising:

[0015] The base has a first cavity.

[0016] The cover is assembled with the base;

[0017] The magnetic attraction device and the magnetic attraction status detection device are both located in the first cavity of the base, and the opening of the first cavity is closed by a cover plate.

[0018] Improved in this invention, the intelligent logistics lock with adsorption detection function further includes a wire rope breakage and overlap detection component for detecting the breakage state of the wire rope inserted into the lock body. The wire rope breakage and overlap detection component is communicatively connected to the main control circuit board.

[0019] Furthermore, in the intelligent logistics lock with adsorption detection function, the steel wire rope breakage and overlap detection component includes:

[0020] The first electrical contact end is located at one end of the inner core of the steel wire in the steel wire rope;

[0021] The second electrical contact end is located at the other end of the inner core of the steel wire rope;

[0022] A resistor is connected in series with the inner core of the steel wire rope and located between the first electrical contact end and the second electrical contact end.

[0023] The first contact detection circuit board is located inside the lock body and is provided with a first spring pin that cooperates with the first electrical contact end to achieve elastic contact with the first electrical contact end.

[0024] The second contact detection circuit board is located inside the lock body and is provided with a second spring pin that cooperates with the second electrical contact end to achieve elastic contact with the second electrical contact end.

[0025] The first contact detection circuit board and the second contact detection circuit board are both communicatively connected to the main control circuit board.

[0026] In a further improvement, the intelligent logistics lock with adsorption detection function also includes a back cover removal status detection component for detecting the removal status of the back cover of the lock body. This back cover removal status detection component is communicatively connected to the main control circuit board.

[0027] Furthermore, in the smart logistics lock with adsorption detection function, the back cover removal status detection component includes:

[0028] The first magnet is disposed on the rear cover of the lock body;

[0029] The Hall sensor, connected to the main control circuit board, detects changes in the magnetic field generated by the first magnet.

[0030] Compared with existing technologies, the advantages of this invention are as follows: In this intelligent logistics lock, after the lock body is magnetically attached to the container using a magnetic attraction device, the magnetic attraction status detection device detects the attraction status signal generated when the lock body is attached to the container. This signal is then sent to the main control circuit board, which determines that the intelligent logistics lock has been attached to the container upon receiving the signal. If the intelligent logistics lock is forcibly detached from the container, the main control circuit board will not receive the attraction status signal from the detection device, and thus determines that the intelligent logistics lock has not been attached to the container. This avoids the situation in traditional logistics locks where the actual status of the lock cannot be accurately monitored due to the cutting of the steel cable. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] This embodiment provides an intelligent logistics lock with adsorption detection function, configured to adsorb onto a container. Specifically, see [link to documentation]. Figures 1-5 As shown, the smart logistics lock of this embodiment includes a lock body 1, a magnetic attraction device 2, a magnetic attraction status detection device, a main control circuit board 4, and a communication device 5. The magnetic attraction device 2 is configured to generate a magnetic force to attract the lock body 1 to the container; for example, the magnetic attraction device 2 uses a magnet. The magnetic attraction status detection device is responsible for detecting the attraction status signal generated when the lock body 1 is attracted to the container. The main control circuit board 4 receives the attraction status signal sent by the magnetic attraction status detection device. The communication device 5 is connected to the main control circuit board 4 and is configured to achieve a communication connection with a remote monitoring party. For example, the communication device 5 here uses a wireless communication device, preferably a 4G communication device, to achieve a communication connection between the smart logistics lock and the remote monitoring party.

[0039] In this embodiment, after the smart logistics lock body is magnetically attached to the container, the magnetic state detection device detects the attachment status signal generated when the lock body is attached to the container. This signal is then sent to the main control circuit board, which determines that the smart logistics lock has been attached to the container upon receiving the signal. If the smart logistics lock is forcibly detached from the container, the main control circuit board will not receive the attachment status signal from the detection device, and thus determines that the smart logistics lock has not been attached to the container. This avoids the situation with traditional logistics locks where the actual status of the lock cannot be accurately monitored due to the cutting of the steel cable.

[0040] Specifically, in this embodiment, the magnetic attraction state detection device includes an elastic element 31 and an adsorption detection circuit board 32. The elastic element 31 abuts against the magnetic attraction device 2 to generate elastic compression deformation when the lock body 1 is adsorbed onto the container. The adsorption detection circuit board 32 is equipped with a linear Hall sensor, which generates a voltage signal based on the polarity and magnetic field strength of the magnetic attraction device 2. The adsorption detection circuit board 32 is communicatively connected to the main control circuit board 4, and the linear Hall sensor can detect the magnetic field strength of the magnetic attraction device 2 to generate a voltage signal. This voltage signal is the aforementioned adsorption state signal. For example, the elastic element 31 is a spring.

[0041] In this embodiment, the magnetic attraction device 2 is located inside the lock body 1, and the elastic element 31 is located in the space formed between the magnetic attraction device 2 and the side wall of the lock body 1; wherein, the side wall is configured to be attracted to the container. For example, the lock body 1 here includes a base 11 and a cover 12, the base 11 is provided with a first cavity 110; the cover 12 is assembled with the base 11; wherein, the magnetic attraction device 2 and the magnetic attraction status detection device are both located in the first cavity 110 of the base 11, and the cavity opening of the first cavity 110 is closed by the cover plate 13.

[0042] In order to detect the breakage and overlap of the steel wire rope inserted into the lock body, the smart logistics lock of this embodiment also includes a steel wire rope breakage and overlap detection component for detecting the breakage and overlap of the steel wire rope inserted into the lock body 1. The steel wire rope breakage and overlap detection component is communicatively connected to the main control circuit board 4.

[0043] As a specific implementation of the wire rope breakage state detection component, in this embodiment, the wire rope breakage lap joint state detection component includes:

[0044] The first electrical contact end (not shown in the figure) is located at one end of the inner core of the steel wire inside the steel wire rope 6;

[0045] The second electrical contact end (not shown in the figure) is located at the other end of the inner core of the steel wire rope 6;

[0046] A resistor (not shown in the figure) is connected in series with the inner core of the wire rope and is located between the first electrical contact end and the second electrical contact end.

[0047] The first contact detection circuit board 61 is located inside the lock body 1 and is provided with a first spring pin that cooperates with the first electrical contact end to achieve elastic contact with the first electrical contact end.

[0048] The second contact detection circuit board 62 is located inside the lock body 1 and is provided with a second spring pin that cooperates with the second electrical contact end to achieve elastic contact with the second electrical contact end.

[0049] The first contact detection circuit board 61 and the second contact detection circuit board 62 are both connected to the main control circuit board 4.

[0050] The steel wire rope breakage and overlap detection component is set up in the above manner. Both ends of the steel wire rope in the smart logistics lock are inserted into the lock body, so that the first electrical contact end makes electrical contact with the first spring pin on the first contact detection circuit board, and the second electrical contact end makes electrical contact with the second spring pin on the second contact detection circuit board, thus forming a circuit. The main control circuit board sends an electrical signal from one end and detects the voltage value of the electrical signal at the other end, thereby detecting whether the lock rod has been cut or overlapped. That is, if the main control circuit board does not detect a voltage value at the other end, it determines that the steel wire rope is broken; if the main control circuit board detects a voltage value at the other end, it determines that the steel wire rope is not broken.

[0051] To detect the removal status of the back cover of the lock body, the smart logistics lock of this embodiment also includes a back cover removal status detection component for detecting the removal status of the back cover of the lock body. This back cover removal status detection component is communicatively connected to the main control circuit board 4. Specifically, the back cover removal status detection component of this embodiment includes a first magnet (not shown in the figure) and a Hall sensor (not shown in the figure). The first magnet is disposed on the back cover of the lock body 1; the Hall sensor is connected to the main control circuit board 4 and detects the change in the magnetic field generated by the first magnet. If the back cover of the lock body is removed, the magnetic field generated by the first magnet will change. After the Hall sensor detects the magnetic field generated by the first magnet and sends the magnetic field status to the main control circuit board, the main control circuit board determines that the back cover of the lock body has been removed when the magnetic field strength changes according to the change in magnetic field strength sent by the Hall sensor. Of course, if the main control circuit board determines that the magnetic field strength has not changed according to the change in magnetic field strength sent by the Hall sensor, the main control circuit board determines that the back cover of the lock body has not been removed.

[0052] In addition, as needed, the smart logistics lock in this embodiment is also equipped with a positioning module and an environmental parameter sensor, which are respectively connected to the main control circuit board. For example, the positioning module here is a common positioning chip such as a Beidou positioning chip or a GPS positioning chip, and the environmental parameter sensor can be a commonly used environmental parameter sensor such as a temperature sensor or a humidity sensor. In the smart logistics lock of this embodiment, a buzzer and an indicator light are also provided on the lock body, both of which are connected to the main control circuit board.

[0053] Of course, the smart logistics lock also contains a rechargeable power supply unit, which is connected to the main control circuit board. The main control circuit board has a charging interface, allowing it to supply power to various power-consuming devices. Additionally, a SIM card that connects to the main control circuit board can be installed inside the lock.

[0054] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
