Embodiment 1

[0022] The invention firstly provides an intelligent fire warning system for an air conditioner. Such as figure 1 as shown, figure 1 It is a structural block diagram of the intelligent fire warning system of the air conditioner provided by the first embodiment of the present invention; for the convenience of description, only the parts related to this embodiment are shown, as shown in the figure:

[0023] An intelligent fire warning system for an air conditioner, comprising: an infrared temperature sensor 10, a rotating device 20 and a microprocessor MCU30. Wherein, the infrared temperature sensor 10 is arranged on the rotating device 20, and forms a rotating scanning device together with the rotating device 20, and the rotating device 20 can rotate back and forth under preset conditions; The surface of the object in the room where it is located performs temperature scanning back and forth, and feeds back the acquired temperature data to the microprocessor MCU30; generally s...

Embodiment 2

[0030] image 3 It is the flow chart of the realization of the fire early warning control method provided by the second embodiment of the present invention; for the convenience of description, only the parts related to this embodiment are shown, as shown in the figure:

[0031] Step S1, control the infrared temperature sensor to rotate with the rotating device according to the preset time-angle condition, scan the temperature of the object surface in the room where the air conditioner is located, and feed back the acquired temperature data.

[0032] After the fire warning function of the intelligent fire warning system is turned on, the infrared temperature sensor is controlled to rotate with the rotating device according to the preset time-angle condition, and the temperature of the object surface in the room where the air conditioner is located is scanned back and forth, and the temperature is sent to the microprocessor. The MCU feeds back the acquired temperature data. It ...

example 1

[0052] Example 1: In the scanning area where the angle is 60°, the results of 30 consecutive temperature scans are as follows:

[0053] Table I

[0054] times

[0055] 4

[0056] It can be seen from the above table 1 that although there are 16 consecutive times from the 5th to the 20th at 150°C, the calculated duration TIME1 is 8 minutes, and the cumulative time TIME2 is also 8 minutes, but none of the alarms are satisfied. conditions, so no alarm was reported. And after the 29th time, the acquired temperature data is 105°C, and at this time, it enters a safe state.

Abstract

The invention belongs to the field of air-conditioners, and particularly relates to an air-conditioner and an intelligent fire hazard early warning system and method thereof. According to the air-conditioner and the intelligent fire hazard early warning system and method thereof, a same infrared temperature sensor is used for both room temperature control and fire hazard early warning. Particularly, a rotation scanning device formed by the infrared temperature sensor and a rotation device rotates according to a preset time-angle condition so that temperature scanning is performed on the surface of objects in a room in which the air-conditioner is positioned and the acquired temperature data are fed back; integrated comparison and discrimination are performed on the received temperature data and a preset temperature-time relation; and fire hazard alarm processing is performed via the internet when the temperature data meet a preset abnormity condition via detection. With application of the air-conditioner and the intelligent fire hazard early warning system and method thereof, a user can be prompted to eliminate fire hazard hidden trouble before fire hazard so that life and property safety of the user is further guaranteed.

Description

technical field [0001] The invention belongs to the field of air conditioners, in particular to an air conditioner and its intelligent fire warning system and method. Background technique [0002] With the advancement of technology, infrared temperature sensors are more and more widely used in air conditioners. However, due to the low temperature range of the infrared temperature sensor itself, the infrared temperature sensor is often used to measure the temperature of the human body or pets in the use environment, while ignoring the application of the infrared temperature sensor in fire warning. [0003] The current fire alarms generally rely on smoke detection, gas detection or air temperature detection. This type of alarm is an alarm after a fire. When the fire alarm is heard, it has already caught fire and caused losses. In fact, fire fighting is not as good as fire prevention. It is better to prevent fire than unburned. It is the best way and method to deal with the al...
