The invention refers to a kind of heat perceptual system of the internet fridge. It comprises temperature perception part, signal transformation part, and control unit. The temperature perception part is used to apperceive the change of the temperature caused by the heat liberation of the microprocessor chipset. The microprocessor chipset is carried on the main board in the internet fridge. The signal transformation part transforms the temperature information apperceived from the temperature perception part to digital signal. The control unit is used to export the notification signal and command signal. If the temperature information transformed to digital signal by the signal transformation part exceeds the reference value, the overheat state of the microprocessor chipset will be informed to the outside, the notification signal will be exported, and the command signal of the work minimum of the microprocessor chipset. So the invention can preliminarily avoid the damage of the hardware and the mistake of the system operation caused by the overheat state of the microprocessor chipset, improve the inner structure and security of the hardware system.

The invention discloses a line-type temperature-sensitive fire detector with an electronic switch component, and the detector comprises a line-type temperature sensing element, a converting box connected with one end of the line-type temperature sensing element and used for real-time detecting temperature of the line-type temperature sensing element or the alarm electric parameters (or sampling values) and an electronic switch component connected with the other end of the line-type temperature sensing element. The line-type temperature-sensitive fire detector with the electronic switch component can detect whether open circuit occurs in the line-type temperature sensing element through using the electronic switch component, and determines whether to give out a fire alarm signal through identifying whether the electric parameter (or sampling value) detected by the converting box exceeds the alarm threshold when the electric switch component is open. Such design not only enables detecting and determining status of the line-type temperature sensing element at any time, but also eliminates the problems of low alarm reliability and low sensitivity in case of open circuit.

The invention relates to an online monitoring device and method for laser cleaning based on temperature perception. The device includes a laser cleaning device and an online monitoring device; according to the parameters of the laser, it is judged whether the object to be cleaned is suitable for the monitoring method; the surface of the object to be cleaned is placed on the Within the beam waist range of the focused laser beam, turn on the laser cleaning device and on-line monitoring device for laser cleaning; perform laser cleaning several times until the voltage change curve tends to be stable, then stop laser cleaning; observe whether there is burning on the surface of the object to be cleaned. If there are burn marks, perform laser cleaning again; if there are no burn marks, the laser cleaning ends. The laser cleaning on-line monitoring device and method can accurately judge whether the object to be cleaned is clean by utilizing the difference in thermophysical parameters of different substances, and solves the problem that the surface of the object to be cleaned cannot be accurately judged whether the surface of the object to be cleaned is clean through manual naked eye observation.

The invention discloses a high-sensitivity composite linear heat fire detector. The high-sensitivity composite linear heat fire detector comprises a temperature-sensitive component, a signal processing unit and a terminal resistor, wherein the temperature-sensitive component comprises an analog quantity cable type linear temperature-sensitive cable and a plurality of temperature sensing modules; the temperature sensing modules are adjacent to one another and are connected to one another in parallel; the distance between each two temperature sensing modules is not greater than 1 meter; and the stability and the reliability of the detector are improved. Compared with a single multi-point cable type linear heat fire detector, the high-sensitivity composite linear heat fire detector has the characteristic that the sensitivity is improved greatly. Moreover, the invention provides an alarming method for the high-sensitivity composite linear heat fire detector.
