Description

 User terminal device based on LoRa and RFID, remote control system and method  

The technical content of the present invention relates to LoRa (Long Range Wide Area Network) and RFID (Radio Frequency Identification), which can be widely used in remote intelligence monitoring such as logistics, traffic flow or personnel. And management.

As we all know, RFID is a non-contact short-distance automatic Transponder system. The principle of operation is basically to set up an RFID reader (RFID Reader) to actively emit radio waves on the control side, and touch the RFID tag (RFID Tag) placed on the user end (goods or wafer card) within a limited sensing distance. , responded by an RFID tag. After receiving the response from the RFID tag, the RFID reader on the control side transmits the status of the RFID tag to the back-end management platform through the signal line or the network for management.

Wherein, since the RFID tags on each user end have a unique tag identification code conforming to their system code, the RFID reader can identify, add or modify RFID in any manner in the system. The function of the tag's wafer data enables efficient automatic sensing and management.

The sensing distance of the above RFID system is related to the form of the RFID tag, and can be roughly classified into a passive RFID tag and an Active RFID Tag RFID tag, wherein the passive RFID tag has a cost less than the built-in power source. It has a low advantage and is therefore often used extensively and extensively on users such as personnel access systems, logistics systems, and vehicle toll collection systems. However, the disadvantage is that the sensing distance is up to 10 meters, that is, when the RFID tag of the user terminal exceeds the sensing distance of the RFID reader of the control terminal, the control terminal and the user terminal cannot perform the inquiry.

For a well-established control system, this situation of inability to answer beyond the sensing distance creates management inconvenience and security loopholes. For example, when a large warehouse is counting goods, it can only use a patrolling handheld RFID reader to approach each RFID tag one by one to perform a sensory inquiry, and the background control software must be patrolled one by one after the RFID reader is patrolled. Statistics and confirmation of the completeness of the goods not only take a considerable amount of time, but also inefficient.

In theory, if the user end uses an active RFID tag that has a built-in power module and an antenna and can actively emit radio waves, the sensing distance between the control terminal and the user terminal can be increased, but the active RFID tag consumes Power and expensive, not suitable for heavy use on the user side, and more importantly, even with active RFID tags, the farthest distance can only reach about 300 meters, for some large-scale large logistics or warehousing In the case of settlement areas, such as seaports, airports, land transfer stations or large warehouses, such sensing distances cannot meet the demand.

In order to solve the above problems, the inventors have tried to use RFID with other wireless transmission systems or communication systems to achieve remote control functions, for example, with a WIFI wireless transmission system, but the WIFI consumes a large amount of power and has a short transmission distance, wherein the transmission distance is short. It is far worse than the active RFID tag, and obviously cannot solve the problem of insufficient RFID sensing distance. Another example is the GSM communication system (Global System for Mobile Communications). Although it is far away, it can be actively transmitted from the user terminal to the base station (control side). However, the system is costly to build and consumes a large amount of power. Used on every client of the control system.

On the other hand, although the LoRa system has a low data rate in terms of data transmission capability, it has low bandwidth (running in the public frequency band), low power consumption, low cost, user-side transmittable signals, and long-distance transmission (currently achievable At least 20 km) and other advantages, and its data transmission capacity is still sufficient to meet the regulatory requirements of data systems, it is very suitable for applications that require a large number of connections; therefore, if you can integrate LoRa with RFID, you will be able to The RFID recognition capability can be effectively extended to achieve long-distance wisdom monitoring and management.
