Embodiment 1

[0032] According to an embodiment of the present invention, a method embodiment of a fire monitoring method is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0033] figure 1 is a flow chart of an optional fire monitoring method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0034] Step S12, reading the thermal image of the target area monitored at the current moment and the collected monitoring data, wherein the monitoring data at least includes: the distance between the monitoring position and the target area and weather information.

[0035] In the above step S12, the monitoring equipme...

Embodiment 2

[0120] According to an embodiment of the present invention, an embodiment of a fire monitoring server is also provided, image 3 is a schematic diagram of an optional fire monitoring server according to an embodiment of the present invention, such as image 3 As shown, the server includes:

[0121] The first reading unit 40 is used to read the thermal image in the target area monitored at the current moment, and the monitoring data collected at the current moment, wherein the monitoring data includes at least: the distance between the monitoring position and the target area and the weather information.

[0122] Specifically, the monitoring equipment includes a thermal imager, a rangefinder, and a meteorological sensor. The thermal imager can monitor the thermal image of the target area in real time, and the thermal imager can scan the ground in all directions or at fixed points to obtain any Thermal image of the area. The range finder can measure the distance between the mo...

Embodiment 3

[0176] According to an embodiment of the present invention, an embodiment of a fire monitoring system is also provided. The system includes:

[0177] thermal imager for monitoring thermal images in the target area;

[0178] A rangefinder for measuring the distance between the monitoring location and the target area;

[0179] Meteorological sensors for collecting current weather information;

[0180] The monitoring server is used to calculate the suspicious fire source threshold based on the thermal image of the target area monitored by the thermal imager at the current moment, the distance between the detection position and the target area measured by the rangefinder, and the meteorological information collected by the meteorological sensor. When the gray value of any one or more pixels in the thermal image is greater than the threshold of the suspicious fire source, it is determined that there is a suspicious fire source area in the target area, and after reading the therma...

Abstract

The invention discloses a fire monitoring method, system and fire monitoring server. Among them, the method includes: reading the thermal image of the target area monitored at the current moment, and the collected monitoring data; calculating the threshold of suspicious fire sources according to the gray value of the thermal image and the monitoring data; when there is any When the gray value of one or more pixels is greater than the fire source threshold, it is determined that there is a suspicious fire source area in the target area; read the thermal image of the target area monitored after the current moment; extract the thermal image of the target area monitored at the current moment image, or the dynamic parameters of the suspicious fire source area in the thermal image of the target area monitored after the current moment, after judging whether the dynamic parameters meet the first preset condition, the fire information of the target area is obtained. The invention solves the technical problem of low fire monitoring accuracy due to the influence of external conditions in the prior art during the fire monitoring process.

Description

technical field [0001] The invention relates to the monitoring field, in particular to a fire monitoring method, system and fire monitoring server. Background technique [0002] At present, forest fires are triggered every year due to natural and man-made reasons, burning large tracts of forest. Most of the forest fires are caused by the failure of small fires to be detected and extinguished in time, and eventually lead to large-scale fires. Therefore, how to timely, accurately and effectively detect the early fire is of great significance. [0003] In the existing monitoring methods, mainly include the following several ways: 1. Utilize satellite to monitor forest fires, but, because satellite monitoring forest fires is subjected to the restriction of satellite transit times and its resolution, the false alarm rate of monitoring results is higher, not necessarily Suitable for real-time monitoring of forest fires. 2. Use a visible light camera to monitor the fire. Since t...
