WiFi hot spot name-based multi-point smoke data acquisition method

The invention relates to a WiFi hot spot name-based multi-point smoke data acquisition method. The method includes the following step that: each smoke sensor is provided with a WiFi module adopted as an AP, and the SSID of the AP contains smoke concentration information, and changes with actually-monitored smoke concentration; when a sampling value changes, the SSID value of the WiFi module is generated and modified according to the sampling value and the information of each smoke sensor such as the name and ID of each smoke sensor, and the AP is restarted, and SSID broadcasting is enabled after the AP is started; and an APP on an intelligent terminal calls an operating system interface, and searches a surrounding WiFi hot spot list through a wireless network card, and the hot spot information of each smoke sensor is parsed from the list, and the current smoke concentration of each sensor is parsed from the SSID value. With the method of the invention adopted, only one smart phone with a WiFi function is required, and the smoke concentration of each acquisition point in a space can be read directly by means of the APP operating on the smart phone, and the method can change in real time.
