Description

Electronic seal structure improvement

technical field

The utility model relates to an improved structure of an electronic seal, especially a passive seal combined with a traditional bullet type container lock and a radio frequency identification function (Radio Frequency IDentification) technology.

Background technique

Generally, the traditional container seal is mainly to avoid the risk of container being dropped or stolen during transportation, but the traditional seal needs to be distinguished by human visual inspection, and it is inevitable that human error or forgery will lead to the failure of the expected function. According to the current method of manual escort, the customs must go to different customs areas for inspection by car, which not only increases administrative costs, but also delays the customs clearance time of manufacturers.

Therefore, some people in the industry have developed radio frequency identification system (RFID) electronic seals, which combine traditional container locks and new seals with RFID (Radio Frequency IDentification) technology, and use the uniqueness and difficult-to-forge characteristics of radio frequency identification systems to reduce the risk of containers being swapped. , and this electronic seal is equipped with a radio frequency chip. Once locked, the information on the radio frequency chip can be read by the reader and transmitted to the back-end system, and can be distinguished by the power supply of the radio frequency chip. Passive (passive) Or active (active), the RFID unit that actively transmits RF signals is called an active tag, which is rewritable and reusable. Due to its internal power supply, it can be used in a wider range of applications than passive tag chips, and can monitor If all containers with a radius of about 50 meters (or even farther) from the reader are improperly opened, the back-end system can immediately find that the containers have been damaged or invaded, but the price of this active radio frequency electronic seal is relatively high. It is tall and has a large appearance. Because it needs to use battery power to transmit signals, it must be replaced regularly, which makes recycling difficult.

The electronic seal of the passive label, because there is no power supply inside, can only perform RF signal reflection or backscatter transmission. It is read-only and cannot be reused, but it is cheap. It is mainly responsible for storing the relevant information of the identified object, such as the name of the product. , serial number, specifications, etc. If the electronic seal is broken and opened in any way, the special design will cause the radio frequency chip to be permanently damaged and unable to operate, so that the reader will not be able to identify it. For example, China Utility Model Patent Application No. 200620039634.9 "UHF Omnidirectional Passive Electronic Container Lock", although the bullet-shaped container lock has a built-in RFID wireless radio frequency device, which can achieve the basic RF signal reflection function, but the distance between the antenna and the RF chip The connection is the signal transmission made by cables covered with plastic materials. In today's society where raw materials are soaring and energy consumption is getting worse, there is a risk of waste of resources, and polyethylene and polyvinyl chloride are not environmentally friendly materials. Great impact on future generations.

In view of the rising awareness of environmental protection and the era of wireless communication, if an electronic seal with a simple structure can be produced and the consumption of raw materials can be saved, the following positive benefits can be obtained:

1. Effectively save material consumption and achieve energy saving and environmental protection.

Two, reduce the production process, thereby reducing the production cost.

3. Easy to use and increase market share.

Therefore, designing a dipole antenna that is simple in structure, easy to assemble, and meets market demand is the problem to be solved by the utility model.

In order to better understand the technical contents of the present utility model, the preferred specific embodiments are described as follows:

Fig. 1a, Fig. 1b are the structural schematic diagrams of a preferred specific embodiment of the present utility model, and refer to other figure shown together, can find out clearly from the figure, the present utility model is mainly by lock portion, and built-in lock The internal radio frequency chip 3 and the antenna 4 are formed. The lock part is composed of a bolt seat 1 and a bolt 2, which can be butted with each other to form a closed shape. The bolt seat 1 is composed of two hollow metal pipes 1a, 1b matched with an insulating block 16, and is covered with a The housing 17 constitutes its main body. One metal pipe body 1a has a closed end 11 at one end of the nozzle, and a feed-in point 111 is provided on the closed end 11. The other metal pipe body 1b has a built-in metal inner pipe 12 with a smaller diameter. One end of the metal inner tube 12 is connected and fixed on one end edge of the metal tube body 1b by a connecting piece 13, so that the metal inner tube 12 is suspended in the metal tube body 1b, and the metal inner tube 12 protrudes from the metal tube body 1b outside. An insulating block 121 is used to insulate and fix a metal conductor 14 inside the metal inner tube 12 , one end of which is connected to the feed-in point 111 , and the other protrudes out of the metal inner tube 12 . The outer side of the metal inner tube 12 is sleeved with a connector 15 for electrical connection, and an insulating block 121 is used to insulate and fix the metal tube body 1b and the metal inner tube 12, and a C-shaped buckle 171 is provided on the inner side of the edge of the shell 17 And water-stop O-ring 172.

The plug 2 is composed of a metal tube body 21 covered with a shell 22. A conical plug 211 with a groove 212 is formed at the front end of the metal tube body 21, and a radio frequency chip 3 and its components are embedded in the rear end. In the hollow tube of the metal tube body 21, a metal conductor 23 is insulated and fixed with an insulating block 24, and one end of the metal conductor 23 is electrically connected with the radio frequency chip 3.

The radio frequency identification system is composed of a radio frequency chip 3 and an antenna 4. The radio frequency chip 3 and the antenna 4 are respectively placed in the above-mentioned socket 1 and the socket 2, and the telecommunication transmission of the radio frequency chip 3 and the antenna 4 is arranged in the socket 1. The metal conductors 14 and 23 in the plug 2 are used to achieve the radio frequency function, wherein the antenna 4 is a dipole antenna, and the metal tubes 1a and 1b are two dipole components of the antenna 4 (as shown in FIG. 3 ).

When the plug 2 is inserted into the plug seat 1 (as shown in Figure 2), the plug 211 at the front end of the plug 2 is forced into the socket 15 on the plug seat 1, so that the metal conductors in the plug seat 1 and the plug 2 14 and 23 are electrically connected, and the connector 15 is electrically connected with the metal tube body of the pin 2. At this time, the C-shaped buckle on the pin seat 1 is simultaneously snapped into the groove 212 on the pin 2. , to achieve the blocking effect, and the water-stop O-shaped washer 172 is used to seal the gap between the bolt 2 and the pin socket 1 to prevent water from flowing into it.

Due to the reduction of the existing plastic insulation layer, its production cost and production process are naturally compared with the existing ones. The technology is cheap, simple, and has the effect of environmental protection and energy saving.

And when the pin 2 and the plug seat 1 are interlocked, the metal conductors 14, 23 in the plug seat 1 and the plug 2 are electrically connected, and the metal inner tube 12 and the metal pipe body 21 are electrically connected through the connector 15. Sexual connection, so the antenna 4 and the radio frequency chip 3 can form a coaxial feeding signal transmission, so as to prevent interference and suppress noise.

The utility model uses the above-mentioned technical means to complete the electronic seal, which has a simple structure and reduces the use of plastics, thereby achieving the effect of environmental protection and energy saving. It has positive benefits for today's society where raw materials are soaring and energy consumption is increasingly serious.
