Description
The invention discloses an intelligent freezing and refrigerating box using a satellite time service temperature sensor, and relates to an intelligent freezing and refrigerating box which is high-grade, civil, large, multi-door and capable of accurately controlling temperature in a partition mode by using a quartz crystal temperature sensor with extremely high precision in satellite time service.
The international utility temperature scale is based on a temperature specification of reproducible equilibrium states (defining fixed points) and a standard interpolation instrument indexed at these fixed points of the international utility temperature scale. In 1968 the international practical temperature scale was divided into three temperature zones, and the temperature values in these temperature zones were defined by a standard platinum resistance thermometer, a standard platinum rhodium (10%) platinum thermocouple and the planck's law of radiation, respectively.
The core component of the quartz crystal thermometer in the prior art is a resonant quartz crystal oscillator, which operates differently from the conventional temperature sensors (platinum resistance thermometer, thermocouple thermometer, etc.), and operates in "resonance", not by "resistance" or "electromotive force" generated by the thermal motion of molecules.
The frequency-temperature characteristic of the quartz crystal oscillator in the prior art is a cubic polynomial curve rather close to a straight line; a. b and c are coefficients of first, second and third degree polynomials respectively, and are related to the cutting type and the vibration mode of the quartz wafer.
The quartz crystal thermometer in the prior art has at least 2 quartz crystal oscillators, one is a reference quartz crystal oscillator with the temperature of 0 ℃, the other is a sensor quartz crystal oscillator used for measuring the temperature, and the measured temperature is obtained by the frequency difference of the two oscillators; to reduce the frequency drift of the reference quartz crystal oscillator, the reference quartz crystal oscillator is usually placed in an oven with precisely controlled temperature; even then, there is still a non-negligible reference frequency drift, and the resolution of the quartz crystal thermometer in the prior art can be 0.001K to 0.0001K, but the accuracy can only be 0.1K to 0.05K.
The refrigerator in the prior art usually uses a temperature sensing resistor (temperature sensing semiconductor) as a temperature measuring element, the accuracy can reach +/-0.2K within one year after verification, but the zero drift can reach 4K or more after the refrigerator is used for years, which is that the evaporator is seriously frozen after the refrigerator in the prior art is used for years in a refrigeration subarea, the temperature sensing resistor is also frozen in the refrigerator, the refrigerator is a freezer, the stored insulin is frozen to seriously affect the drug effect, and the refrigerator also becomes an electric tiger.
Because the precision of the temperature-sensing resistance sensor of the refrigerator in the prior art is limited, the refrigerator in the prior art is not understood so far, and the temperature difference between the temperature-sensing resistance sensor and the preserved food and articles is K; what the cooling curves of the food materials and the articles which are just put into the refrigerator at different depths are; temperature distribution in the storage space of the refrigerator; the optimal arrangement position of the temperature sensing element; the evaporator works normally and the temperature curve and power consumption change condition of the evaporator after ice blockage occurs; the optimal sensor temperature for fresh-keeping and non-freezing is what degree;
the refrigerator in the prior art still uses bimetallic strip as temperature control element, and its temperature control precision is worse, and the temperature management and control is more extensive.
(III) the invention content:
the technical problem to be solved is as follows:
the problem that the temperature measuring element of the refrigerator in the prior art is low in measurement precision and large in zero drift, and an evaporator of a cold storage part is often large in ice lump after being used for years, and a temperature sensing resistor is also frozen in the evaporator; the cold storage part is a freezing box, and the curative effect of medicines such as insulin is damaged; the drawer can not be pulled open, and the refrigerator becomes an electric tiger; the temperature of the preservation box at 0 ℃ has large drift and large fluctuation range, and the use experience is not good, particularly the long-term use experience is not good; the freezing temperature of the freezing part is not accurately controlled and displayed, and the freezing temperature does not reach the standard, so that the quality guarantee period and the eating safety of food materials are influenced; there is a lack of convenient man-machine communication means.
