Embodiment 1

[0119] Embodiment 1: as figure 1 , the whole system design consists of the following six parts:

[0120] (1) The controller part, the system has the ability to display and input data.

[0121] (2) Environmental monitoring subsystem. Arrange appropriate sensors at each required position on the site to form an environmental perception network to obtain real-time data of various environmental information on the site, such as temperature, humidity, air quality, etc. The system also uses these data as the basis for judging and realizing the intelligent linkage system .

[0122] (3) Intelligent access control subsystem. Using RFID technology, the access control card is read through the card reader to obtain authorization information. Every time the card is swiped, the system will intelligently identify the user's information. If it is judged to be a member of the site, the access control system will be automatically opened to allow entry. If it is judged that the user's swiping ...

Embodiment 2

[0195] like Figure 17 , the spraying device is a rotary spraying device set on the ceiling above the site or on the bracket above;

[0196] At this time, (1) there are multiple fire sensors, which are distributed in an array; at this time, if a certain sensor or sensor detects that there is a fire in a certain area, the rotary sprinkler will control the rotation of the spray gun on the rotary sprinkler. Aim at the area to implement sprinkler fire;

[0197] Or, (2) the fire sensor uses an infrared camera to obtain the position of the fire point through image processing, and then the rotary sprinkler device controls the rotation of the spray gun on the rotary sprinkler device to aim at the area where the fire point is located to implement spray fire extinguishing.

[0198] The rotary spraying device includes a support base, a rotary platform 118 and a rotary platform drive motor 121; the spray gun 108 is arranged on the rotary platform;

[0199]The rotary platform drive motor...

Embodiment 3

[0202] Embodiment 3: adopt water jet truck to implement water spraying

[0203] like Figure 18 , a sub-camera 114 and an auxiliary spray gun 115 are provided on the crawler water spray vehicle.

[0204] The crawler water spray vehicle is connected with the main water tank through a water pipe; and the crawler water spray vehicle is provided with an auxiliary water tank 113. The sub-camera is used to monitor the water spray action and the fire scene status, the auxiliary spray gun is used to spray water, and the tracked water spray vehicle has a wireless communication module, which is controlled by a remote terminal (such as a mobile phone).

[0205] Fire extinguishing control method: Step 1: Monitor the location of the fire point; Step 2: MCU controls the sprinkler device to extinguish the fire;

[0206] In step 1, there are two methods for monitoring the location of the fire point: (1) detecting the location of the fire point through multiple fire sensors arranged in an ar...

Abstract

The present invention discloses a field monitoring and safe-protection control method based on the internet of things. The method comprises the steps of: the step 1: monitoring a position of a fire point; and the step 2: allowing an MCU to control a spraying device to enforce fire extinguishing. In the step 1, there are two methods for monitoring the position of the fire point, wherein the two methods comprise detection the position of the fire point by employing a plurality of fire sensors arranged in an array mode and monitoring of the position of the fire point by employing an infrared camera and based on image processing; and in the step 2, there are two methods for fire extinguishing, wherein the two methods comprise (1) controlling of a nozzle of a firing area (subarea) for enforcement of water spray and (2) controlling of a spray gun for rotationally aligning the fire point to enforce water spray fire extinguishing. The field monitoring and safe-protection control method based on the internet of things is abundant in functions, easy to control and high in safety reliability and has a fire prevention and control function.

Description

technical field [0001] The invention relates to an on-site monitoring and security control method based on the Internet of Things. Background technique [0002] The monitoring site generally refers to the home site or storage site, and the biggest hidden danger in this type of site comes from fire; [0003] In the prior art, although there is a fire prevention and control system, such as a building automation intelligent system based on smoke detectors and nozzles, there are defects of single control and imperfect functions. If the effect of intelligent spraying cannot be realized, intelligent spraying is Refers to the function of controlling the spraying area and controlling the spraying angle. Moreover, existing sprinklers are connected to the Internet of Things, and there are blind spots in monitoring. [0004] Therefore, it is necessary to design a new on-site monitoring and security control method based on the Internet of Things. Contents of the invention [0005] ...
