See figures 1-4 for a multi-functional electronic seal for a container. The electronic seal includes: the lock comprises a lock body 4, a lock rod 8 and a lock head 1.

Specifically, the lock body 4 includes a first housing 9, a first battery 5 mounted in the first housing 9, a first PCB 3, and a second PCB 6. One end of the lock rod 8 is fixedly connected with the lock body 4, and the other end can be clamped with the lock head 1. The end part of the lock rod 8, which is positioned at one side of the lock head 1, is internally provided with a Hall sensor 2 which is used for detecting whether the magnetic field exists in the lock head and the intensity of the magnetic field.

The first PCB 3 comprises an A/D sampling module for controlling the Hall sensor 2 to acquire signals; the second PCB 6 includes a positioning module and a communication module configured to send a signal detected by the hall sensor 2 to a control platform, where the control platform sends an alarm signal when the hall sensor 2 does not detect a magnetic field or the detected magnetic field strength is different from a preset magnetic field strength.

The battery 5 is used for powering the hall sensor 2, the first PCB (3) and the second PCB (6). The battery may be a disposable telephone or a recyclable battery.

A lock hole 15 is formed on the lock head, and the lock head 1 is used for clamping the lock rod 8 passing through the lock hole and generating a magnetic field for detection by the Hall sensor 2. Specifically, the lock cylinder 1 includes a second housing 10, and the second housing 10 includes a top surface, a bottom surface, and side walls. The lock hole 15 penetrates through the top surface and the bottom surface, and the hole wall of the lock hole, the top surface, the bottom surface and the side wall of the second shell jointly enclose a cavity of the second shell 10. An induction magnet 11 is arranged in the second shell 10 at one side of the lock hole 15 and is used for generating a magnetic field for detection by a Hall sensor; the second shell 10 at the other side of the lock hole 15 is internally provided with a clamping tongue 12 and a spring 14, one end of the spring 14 is fixedly connected with the inner wall of the second shell 10, and the other end is connected with the clamping tongue 12. A hole for extending the clamping tongue is formed on the wall of the lock hole; the other end of the tongue 12 extends from the lock hole 15 under the action of the spring 14. A groove for accommodating the clamping tongue is formed at the end part of the lock rod 8; the latch 12 is snapped into a recess in the lock lever 8 during the process of extending the lock lever 8 into the lock hole.

The electronic seal with the structure is suitable for goods needing to be closely monitored, namely, the electronic seal is disposable, and when unlocking is needed, the locking head is directly sheared by tools such as pliers and the like, and the spring is discarded, so that the opening door is opened in a unsealing way.

In case no tight monitoring of the goods is required or in case it is desired that the electronic seal can be reused, an iron block 13 can be added in the second housing 10 and a corresponding external magnet can be provided. An iron block 13 is connected between the clamping tongue 12 and the spring 14; when the lock needs to be opened, the iron block compresses the spring 14 under the action of the external magnet, the clamping tongue 12 is retracted, and the lock rod 8 is separated from the lock.

In order to facilitate the mounting of the components within the housing, it is preferred that the upper end of the first housing 9 is open and is detachably closed by an upper cover 7. In order to prevent malicious opening, a light sensor is further installed on the second PCB, and after the upper cover 7 is opened, a signal sensed by the light sensor is transmitted to the control platform through the a/D sampling module and the communication module, and the control platform sends an alarm signal. In this case, the first housing 9 may be a cylindrical housing having an open upper end, and the upper cover is screw-coupled with the first housing 9.

In the electronic seal, the communication module adopts a GPS module or a GSM module. The first housing 9 and the second housing 10 are both plastic housings, and the second housing 10 is flat.

The working process of the electronic seal is as follows:

the electronic lock locks the container, and the Hall sensor detects the existence of the magnetic field of the lock head and the intensity of the magnetic field. In the normal transportation process, the magnetic field strength detected by the Hall sensor is unchanged. When the lock head is damaged or replaced, the magnetic field intensity detected by the Hall sensor changes; or when the lock body is damaged, the signal detected by the optical sensor changes, and the control platform timely alarms after receiving the changed signal, so that emergency measures can be timely taken according to the time and place information of the alarm.

In addition, the battery also has a low-voltage alarm function. When the battery voltage is low or the equipment is powered off, the control platform sends out a corresponding alarm signal.

In the utility model, the lock head shell is flat, and the lock head is matched with the lock rod, so that the matching state of the lock rod can not be changed once the lock rod is clamped into the lock head.

For goods needing to be closely monitored, the lock head can be made into a disposable (the inside is a nonmetallic part, the iron block 13 is not added), and when the goods need to be unlocked, the lock head is directly sheared by tools such as pliers, and the spring is discarded, so that the unsealing and door opening are realized. For goods which are not monitored closely, the lock head can be made into a recycling type, the lock core clamping position is of a professional magnetic structure, the iron block 13 and the external magnet are added, and the unlocking is realized by sucking the compression spring.
