In another alternative embodiment, the warehouse may be further divided into a plurality of sub-areas by area division, for example, as shown in fig. 4, the area of the warehouse may be divided into 9 sub-areas. It should be noted that, in the present application, the number of sub-areas is not limited, and the area of the warehouse may be divided into 18 sub-areas and 36 sub-areas.
After the plurality of sub-areas are obtained through division, one or more temperature sensors are arranged for each sub-area, wherein one sub-area corresponds to one group of sensors. As shown in fig. 4, the warehouse corresponds to 9 sub-areas, each sub-area containing a set of sensors. At this time, the installation positions of at least one group of sensors are as follows: the top of the warehouse; walls of a warehouse; a designated location in the warehouse other than the roof and walls.

In addition, according to the special requirements of different areas in the warehouse, a corresponding preset temperature interval can be set for each sub-area, that is, different preset temperature intervals can be set in different sub-areas, for example, when the temperature in the sub-area A is higher than 50 ℃, an alarm is triggered to give an alarm; the temperature in the B sub-area triggers an alarm to alarm when the temperature is more than 53 degrees.
As shown in fig. 4, in the present application, the distance between any two adjacent temperature sensors may be a predetermined value. That is, in the present application, a distance between any two adjacent temperature sensors among the temperature sensors is less than or equal to a preset distance, wherein the preset distance may be set to be 5 meters.
Specifically, since the effective temperature measurement radius of a single DS18B20 temperature sensor is about 5 meters, the distance between any two adjacently mounted temperature sensors is set to a maximum of 5 meters. For a warehouse with a large area, the number of temperature sensors should be increased appropriately.
In the present application, the considerations of the manner of mounting the temperature sensor include the following: DS18B20 is a transistor temperature sensor, should give waterproof and dampproof treatment, the outside wraps up the water proof membrane to guarantee long-term stable operation; the position for installing the temperature sensor is required to avoid the strong magnetic field; the connecting cable of the temperature sensor needs to be firmly fixed.

When the number of the temperature sensors is large, the bus driving problem of the controller may be caused by arranging too many DS18B20 temperature sensors on a single signal line, so the present application chooses to arrange a plurality of signal lines (e.g., 3 signal lines), and each signal line is connected with a plurality of DS18B20 temperature sensors (e.g., 8 DS18B20 temperature sensors), so as to ensure the stability and the usability of the whole system.
Fig. 5 is a schematic circuit diagram of the temperature sensor. As can be seen from fig. 5, the number of DS18B20 temperature sensors is 24, wherein JP1 to JP8 are a first group of temperature sensors connected to a data input port of a controller through one signal transmission line. JP9 to JP16 are a second group of temperature sensors connected to a data input port of a controller through a signal transmission line; JP17 to JP24 are a third group of temperature sensors connected to a data input port of a controller through a signal transmission line.
In the present application, the temperature sensor connected to each signal transmission line may be determined according to the installation position of the temperature sensor in the warehouse, for example, the temperature sensors with a short installation position may be grouped into one group, and the temperature sensors in the group of temperature sensors may be connected to the controller through one signal transmission line, so as to obtain the circuit connection relationship shown in fig. 5.
In an alternative embodiment, the sound alarm device may be a buzzer, wherein the connection relationship between the buzzer and the controller is shown in fig. 6, and in fig. 6, U1 represents the controller.

And in the display interface, the temperature detection result of each sub-area of the warehouse is contained. Assuming that the number of sub-areas of the warehouse is 9, each of the 9 squares as shown in fig. 7 represents a temperature detection result of one sub-area. If the grid is displayed as green, it indicates that the temperature in the sub-area is lower than a set "safe temperature (i.e., a first preset temperature threshold)", that is, it indicates that the temperature in the sub-area is normal; if the grid is displayed in yellow, the temperature of the subarea is between the set safety temperature and the set alarm temperature (namely, a second preset temperature threshold), and the subarea is in danger; if the box is displayed in red, it indicates that the temperature of the sub-area is higher than the set "alarm temperature", i.e. that the sub-area has reached the fire alarm temperature.
