Problems solved by technology
Although this kind of kitchen gas stove fire safety notification device is provided with a temperature relay, the sensitivity of this temperature relay is relatively poor. Since it is arranged near the gas stove hob support, it cannot accurately sense whether there is dry burning in the furnace body. Therefore, this The practicability of the kitchen gas stove fire safety notification device is greatly reduced
[0003] In addition, in the chemical laboratory, there are also hidden dangers of accidents caused by dry burning of containers such as beakers.

Embodiment 1
[0050] Embodiment 1: as Figures 1 to 5 , a safety monitoring method based on non-contact temperature detection, the control box 1 is connected with a connector, and the end of the connector is provided with an infrared temperature sensor 3;
[0051] Include the following steps:
[0052] Step 1: Align the end of the connector with the container being heated, and the infrared temperature sensor detects the temperature of the outer wall of the container 9;
[0053] Step 2: The control circuit in the control box compares the temperature value detected by the infrared temperature sensor with the preset temperature value. If the temperature value detected by the infrared temperature sensor is greater than the preset temperature value, an alarm is activated; the user is reminded Go to the scene in time for processing; the preset temperature value is set to 160°C.
[0054] The container is a beaker, pot or furnace placed on a heating device; the heating device is a microwave oven o...

The invention discloses a security monitoring method based on non-contact temperature detection, wherein a control box (1) is connected to a connecting part; and an infrared temperature sensor (3) is disposed on the tail end of the connecting part. The method comprises the steps that at the first step, the tail end of the connecting part is aligned at a container being heated, and the infrared temperature sensor detects the temperature of the outer wall of the container (9); and at the second step, a control circuit in the control box compares the temperature detected by the infrared temperature sensor with a preset temperature, wherein if the temperature detected by the infrared temperature sensor exceeds the preset temperature, alarming can be started, a user is reminded to deal with the problem on site in time. The container is a beaker, a pot or a furnace placed on a heating device. The security monitoring method based on the non-contact temperature detection has the advantages that the design is clever; implementation is easy; empty heating of containers such as pots or furnaces can be prevented effectively; sensitivity is high; and security is high.
Description
technical field [0001] The invention relates to a safety monitoring method based on non-contact temperature detection. Background technique [0002] Existing monitoring devices for kitchens mostly adopt temperature sensors to detect indoor temperature, and adopt infrared sensors to sense whether there are people in the kitchen. For example, Chinese patent No. 201269558 discloses a fire safety notification device for kitchen gas stoves (application No.: 200820014489.8), including temperature relay RJ1, human body induction pyroelectric infrared sensor, radio transmission system, multiple radio receiving notification devices and intelligent gas valve, temperature relay RJ1 is installed near the gas stove hob support; temperature relay RJ1 is connected with human body induction Pyro-infrared sensors, intelligent gas valves, radio transmission systems, and power supply electrical connections form a gas monitoring system; multiple radio receiving notification devices are fixedly ...
