Can handheld barcode terminals use in fire safety accident

1.the application background of RFID technology
Today, with the rapid development of information technology, the new generation of information technology marked by the Internet of Things has become the hottest research object in the 21st century. However, in the Internet of Things industry, RFID radio frequency identification technology has become one of the fastest growing technologies. With its unique advantages, radio frequency identification technology is widely used in logistics warehousing, clothing retail, medical, transportation, anti-counterfeiting, asset management, aviation manufacturing, intelligent building and other fields. RFID technology is a non-contact automatic identification technology. RFID technology can recognize objects in high-speed motion and can read multiple labels at the same time, which is quick and convenient. Handheld terminal products that are read shortly are not affected by harsh environments such as oil and dust, and can be better used in buildings.
2.the working principle of RFID handheld barcode terminalhandheld barcode terminal
The principle of RFID handheld barcode terminal: When the read/write device is ready to send relevant information, the main form is to transmit the encoded information through the carrier signal sent by one of the frequencies and finally transmit it through the antenna. The pulse signal is received in time, the relevant components in the tag decrypt and modulate the signal, are transmitted to the reading and writing by the card antenna through the steps of encryption and modulation, and then the reading and writing device performs decoding. The signal is finally sent to the information system for processing. At this time, the signal is displayed as a write command, and the content included in the EEPROM is modified at this time, but the error information is returned when the password and the authority are determined to be incorrect.
3. the application of RFID handheld barcode terminal in intelligent building fire detection system
Nowadays, with the rapid development of the economy and society, there are more and more high-rise buildings, and fire accidents often occur. According to the official WeChat news report of the Fire Department of the Ministry of Public Security; in 2016, a total of 312,000 fires were reported nationwide, 1,582 people were killed, 1,065 people were injured, and direct property losses amounted to 3.72 billion yuan. Behind this creepy number, the hidden fire safety issue. Therefore, the fire safety of high-rise buildings has become a hot topic of public concern. How to better solve, control, and reduce the occurrence of such accidents has become a common problem faced by everyone.
In the early days of the fire, it is difficult for firefighters to get the specific location of the fire, thus delaying the fire time. Nowadays, RFID technology develops rapidly in China. In order to protect the safety of people and property, RFID technology can be cited in fire alarm detectors to give full play to its advantages and build a fire alarm with strong adaptability, high safety and faster and more accurate data information. Management system. The system deploys a position monitoring and monitoring reader in the fire alarm detector in the building to identify the position information of the tag in the building, and monitor the monitoring situation of the fire alarm detector and whether it is faulty in real time, if a fire or When a fault occurs, it can be promptly fed back to the fire monitoring center management system. Therefore, it is possible to better discover the fire and save the firefighters time to find the fire source. Reduce casualties and property damage.fire accident
