The traditional wired smoke alarm system can not achieve the remote transmission of alarm information.Alarm information can not be obtained in time, and it is easy to miss the best time to control the fire.In order to solve this problem, the wireless smoke alarm system based on 4G cellular modem module can be used in the intelligent era.The system takes STM32 high-performance 32-bit microcontroller as the core, and uses the network communication function of 4G cellular modem module.After the smoke alarm signal is monitored, the alarm information is transmitted to the mobile phone terminal of the user at the first time.
The 4G cellular modem plays a key role in the smoke alarm system.The smoke alarm system usually consists of a smoke detector, a control panel and an alarm device.The 4G cellular modem is responsible for transmitting the monitored smoke data to the remote monitoring center or the user's mobile phone.Its application mainly includes the following aspects:
The 4G cellular modem communicates with the smoke detector and control panel via a wireless or wired connection.The collected smoke data will be transmitted to the remote monitoring center in time, so as to give an alarm and take appropriate measures in time.
4G cellular modem can realize remote monitoring and operation.The state of the smoke detector is monitored and the alarm information is obtained in real time, and remote setting and control can be carried out at the same time.Make sure the system is working properly.
4G cellular modem can monitor the operation status of the smoke alarm system, find the fault in time and give an alarm.It is convenient for engineers to carry out remote diagnosis and maintenance.
The 4G cellular modem is used as the data transmission and remote monitoring equipment in the smoke alarm system, which improves the stability and reliability of the system.At the same time, it also provides users with a more convenient way of remote monitoring and management.
