Description

An ancient building monitoring and protection system and method based on RFID technology

technical field

The invention belongs to the field of wireless communication, and in particular relates to an ancient building monitoring and protection system and method based on RFID technology.

Background technique

Radio Frequency Identification (RFID) technology, also known as electronic tags, is a communication technology that emerged in the 1990s. It can identify specific targets and read and write related data through radio signals without the need for identification between the system and specific targets. Establish mechanical or optical contact. The integrated circuit inside the RFID tag can be driven by receiving electromagnetic waves of a specific frequency. When the tag receives a signal of sufficient strength, it is woken up so that it can send data to the reader. These data include not only ID numbers (globally unique codes), but also data pre-existing in EEPROM (electrically erasable programmable read-only memory) inside the tag. The tag can be passive, relying only on the resonance generated by electromagnetic waves on the resonant circuit to provide the working voltage for the circuit; it can also be active, after being awakened, the internal power supply of the tag is used to supply the voltage required by the internal circuit to Generate external signals. Both types of tags have their own advantages and disadvantages: Generally speaking, passive tags are cheap and small in size, but have a shorter transmission distance and smaller memory capacity; while active tags have a longer transmission distance and larger memory capacity , but the volume is large and the price is high.

RFID is considered to be one of the top ten technologies that will affect the future. Its application prospects are very extensive, and it has been used in many fields, such as banknotes and product anti-counterfeiting, ID cards and electronic tickets, electronic toll collection systems, livestock or wild animal identification, patient Identification and electronic medical records, logistics management, luggage sorting, access control systems, etc.

Detailed ways

Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

Fig. 1 is a schematic diagram of an ancient building monitoring and protection system based on RFID technology provided by a preferred embodiment of the present invention. As shown in Figure 1, the ancient building monitoring and protection system based on RFID technology provided by the preferred embodiment of the present invention includes a collection device 1, a reader 2, a server 3 and a client 4, and the collection device 1 and the reader 2 are short-range wireless connection, the reader 2 and the client 4 are connected to the server 3 respectively. Wherein, the acquisition device 1 is installed on an ancient building, which includes a sensor module 11 and an RFID tag 12 , and the sensor module 11 is connected to the RFID tag 12 .

Specifically, the sensor module includes a temperature sensor, a humidity sensor, a pressure sensor and a level sensor. Among them, a temperature sensor refers to a sensor that can sense temperature and convert it into an available output signal, which is divided into two categories: contact type and non-contact type. The temperature sensor described in this embodiment is a contact type temperature sensor, which is used to sense the temperature of ancient buildings. The change. The humidity sensor covers a specific part with a film made of moisture-sensitive material. When the water vapor in the air is adsorbed on the moisture-sensitive film, the resistivity and resistance value of the element will change, that is, the output of the sensor will change. Changes occur, and this feature can be used to measure the humidity of ancient buildings. In this embodiment, both the pressure sensor and the level sensor are existing products, and their working principle is a mature technology in the industry, so it will not be described in detail here.

In this embodiment, the RFID tag is a passive RFID tag, which has the advantages of small size, will not destroy the coordination and unity of the ancient architectural style, and has a metal coil, which generates electric energy through electromagnetic induction to supply its own electric energy consumption. In ancient buildings, an RFID tag is installed at a certain distance, and it is used as a node to monitor the condition of ancient buildings within a certain range. The RFID tag can receive the physical information collected by the sensor, has a certain local storage capacity, and sends the tag ID number and ancient building information to the reader at regular intervals. In addition, in order to protect architectural relics, the reader will be deployed outside the ancient building (within 300m to 600m from the ancient building), with a built-in 3G communication interface, which can be connected upward to the mobile communication network.

Fig. 2 is a flowchart of an ancient building monitoring and protection method based on RFID technology provided by a preferred embodiment of the present invention. As shown in FIG. 2 , the RFID-based ancient building monitoring and protection method provided by the preferred embodiment of the present invention includes steps S1-S3.

Step S1: The RFID tag stores the physical data of ancient buildings collected by the sensor module, and sends the information to the reader.

Specifically, in this step, the information sent by the RFID tag includes the ID of the RFID tag and the physical data of ancient buildings collected by the sensor module. The physical data includes the temperature, humidity, pressure data and inclination angle of the ancient building.

Step S2: the reader forwards the information to the server, and the server analyzes the information to determine whether the state of the ancient building is abnormal.

Specifically, the client logs in to the server to set the thresholds of various indicators of ancient buildings, and when the server judges that the indicators in the received information exceed the thresholds, it sends an alarm to the client. Here, the various index thresholds include corresponding temperature, humidity, pressure and tilt angle thresholds. If the server judges that the state of the ancient building is normal, the server continues to wait for the next message sent by the reader.

Step S3: If yes, the server sends an alarm to the client.

Specifically, the client can realize 24-hour uninterrupted monitoring of ancient buildings according to the real-time alarm from the server. This avoids a series of serious problems caused by maintenance personnel ignoring the poor drainage of ancient buildings, realizes the need for no manual intervention, and greatly reduces the cost of monitoring and maintenance of ancient buildings.
