Embodiment 1
[0042] This embodiment provides a high temperature early warning method, figure 1 It is a flowchart of a high temperature early warning method according to an embodiment of the present invention, such as figure 1 As shown, the method includes:
[0043] S101, monitor the temperature value of each heat source unit in the working space of the sensor; wherein, the monitored surface of each heat source is divided into multiple heat source units, and the projection surface of the working space of the sensor is divided into multiple projection units, the The heat source unit has a one-to-one correspondence with the projection unit.
[0044] In this embodiment, the monitored surface of each heat source can be divided into multiple heat source units on average according to the area, the projection surface of the working space of the sensor is divided into multiple projection units on average according to the area, and the projection surface of the working space of the sensor is divide...
Embodiment 2
[0050] This embodiment provides another high temperature early warning method, figure 2 is the projection map of the heat source on the projection surface. In the specific implementation process of the high temperature early warning method of the above-mentioned embodiment, the detected surface of the heat source may be relatively large, and the temperature values are different in different regions of the same heat source. Therefore, as figure 2 As shown, on the basis of the above-mentioned embodiments, the detected surface b of each heat source can be divided into one or more area units b1 according to the average area, that is, the heat source unit, and the detected surface b of each heat source is within the sensor a There is a projection area c corresponding to the projection surface of the workspace, and the projection area c includes a plurality of projection units c1, and each area unit b1 on the detected surface of the same heat source b corresponds to each projecti...
Embodiment 3
[0057] This embodiment provides another high temperature early warning method. In this embodiment, an intelligent sensor is installed in the air conditioner, and the ambient temperature is identified through the sensor, and the monitoring result of the intelligent sensor is sent to the building security system. Specifically, if the environment In areas where the temperature is too high (for example ≥ 57°C) exceeds the normal range, the smart sensor can immediately identify the abnormal temperature information, and send the abnormal temperature information to the background data management system of the air conditioning unit, and through the mobile smart terminal or networked terminal Transmit to the user or building manager, and at the same time send the abnormal temperature information to the building security system, and display it through the management terminal of the building security system. If the temperature continues to rise to 62°C, the building security system can als...
