To achieve the above object, the utility model provides a kind of NB_IoT humiture observation system for museum, Including control panel, temperature humidity sensor module, NB_IoT communication module circuitry, network server, mobile terminal, warning device, The control panel includes main control singlechip, display screen, NB_IoT communication module interface, standard I/O port and IIC interface, described warm and humid Spending sensor module with control panel is connected by standard I/O port, and the NB_IoT communication module and control panel are to pass through standard I/O port connection.By wired connection, the control panel and network server are logical for the temperature humidity sensor module and control panel Cross the connection of narrowband Internet of Things, the mobile terminal connect with network server by 2G/3G/4G signal, the warning device and Network server is connected by internet.

The control panel receives the alarm signal that temperature humidity sensor module is sent, and alarm signal is sent out through network server It is sent to warning device while extracting the parameter in database and judge that the position of field module and parameter are sent to as display data Mobile terminal.

The temperature humidity sensor module uses the module of model DHT11, can detecte the humidity and temperature of ambient enviroment Degree.

The NB_IoT communication module is designed based on the Development of Module of model BC95-B5, and 3.3V power supply, band resets electricity Road carries the mountable SIM card of eject sim card slot.

The network server obtains outside current data and historical data except through data-query interfaces, can also pass through The mode of message subscribing obtains real time data.

The mobile terminal receives the APP message that network server is sent or short message is reminded.

The warning device receives the alarm signal that network server is sent and issues sound-light alarm.

The beneficial effects of the utility model are: the utility model provides a kind of NB_IoT temperature and humidity prison for museum Examining system, temperature humidity sensor module acquire museum in or historical relic case in ambient temperature and humidity information, pass through NB-IoT wireless network Network is transmitted, and can observe data information live in museum or in historical relic case in real time in mobile terminal.Use NB_ IoT new technology narrowband Internet of Things promotes 100 times of covering power compared to GPRS, the more existing mobile cellular network of stability is higher by 50-100 times or more, operation power be lower than GPRS, the stand-by time of equipment is in existing battery without can be used in the case where charging 2-3, NB-IoT aim at Internet of Things preparation, more excellent relative to 2G/3G/4G network performance.Access Wide Area Network is not needed Realize network alarm, installation cost is low, convenient for laying.
