The Design Of Alarm With Identification Function

In recent years, Chinese economy develops rapidly; People’s living standards have beengreatly improved. People’s awareness of security is improving. With the rapid develop ofinformation technology; people put forward higher requirements for safety guard system. Thedetectors are developing in the direction of intelligence.After the analyze of the current detector, we found that most of the design is aboutsensors and software. Few researches have been done on the integration of Radio FrequencyIdentification technique, sensor technology and network technology. In this case, we usedRadio Frequency Identification technique, sensor technique and network technology in ouralarm system. It has resolved the problem that the alarm could not identify a person and notalarm. At the same time, it achieved network alarm. Thus, when the thieves break into yourhouse, we can inform the guard in good time and the guards could find the right locationseasily. The guard could deal with the accident in time. So we can minimize losses when theburglary has happened.This detector not only has the function of fire detection, but also has the function ofburglar alarm. The alarm system uses the STC89C52as the core, the sensors to collect alarminformation and the RFID reader to read the card number. When the alarm signal arrived, thealarm system identifies the card first.if it could not receive a valid card number at the sametime, it will send the alarm message to computer. The computer will find the address wherethe alarm happened. The article focuses on describing the design of hardware and software ofthe alarm system.In this paper, the principle schematics and the PCB have been designed. At the sametime,the driven programs has also been designed. The paper made a detail introduction of thenet work transport in the alarm system. The cost and the expansibility have been considered inthe design of the alarm system, so the alarm system will have higher marked value. At the endof paper, the function of the alarm system has been tested.This alarm could identify the people who come into the area with a RFID card. It alsohas the function of identifying people. The traditional alarms do not have this function. Itwould not alarm when the alarm could identify the card. This could avoid a lot of troubles. This alarm has great significant for the bank, because the bank defends against the intrudersthrough technological and the guard.
