Property.Moreover, the present invention combines closely the advantage of ultrasonic distance-measuring sensor and pyroelectric infrared sensor, by a variety of biographies
Sensor effectively combines the characteristics of giving full play to them, improves the stability of alarm, while reduces rate of false alarm, for future
Cultural relics protection system is significant.
Brief description of the drawings
Fig. 1 is the block diagram of historical relic's protection device of the utility model based on wireless sensor network.
Fig. 2 is the arrangement schematic diagram of the utility model node unit.
Embodiment
As shown in figure 1, historical relic's protection device of the utility model based on wireless sensor network, the device includes upper
Machine, WiFi module, ZigBee telegons and at least one terminal node；
Wherein, the terminal node is connected with the ZigBee telegons by ZigBee wireless networks, the ZigBee
Telegon is connected by the WiFi module with the host computer.
The device also includes warning device, and the warning device is connected with the terminal node.
The warning device includes buzzer and LED.
The terminal node includes Temperature Humidity Sensor node, ultrasonic sensor node, Smoke Sensor node and people
Body infrared sensor node.
The Temperature Humidity Sensor node is DHT-11 Temperature Humidity Sensors, and the sensitive height of the sensor, cost are low, pin
Lack, only three pins, i.e. VCC, DATA, GND.
The ultrasonic sensor node is US-100 ultrasonic distance measuring modules, and the module can realize that the non-of 0~4.5m connects
