Description
Technical Field
The invention relates to the field of physiological parameter detection, in particular to a temperature measurement control system applying hair recognition.
Background
As the thermal load increases, the human body will produce a series of thermo-physiological reactions: increased heart rate, increased core temperature, increased skin temperature, and increased sweat metabolism. The degree of the thermo-physiological reaction varies with the intensity of the thermal environment. The extent of these thermophysiological reactions reveals the magnitude of the thermal load of the thermal environment in which the human body is exposed. Therefore, it is an effective method to control the thermal stress applied to the human body according to the physiological response of the human body. During the working process, one or more physiological response values of the human body are measured, and the thermal stress on the human body is controlled below a certain level, so that the working efficiency and the working safety of workers are ensured.
For example, body temperature is one of the most important parameters of the human body. The human body maintains a relatively constant body temperature by taking food, while also taking or losing heat from the environment by convection, radiation, and evaporation of perspiration. The physiological function of the human body determines that the body temperature needs to be kept approximately constant to ensure that all functions of the human body are normal. The physiological response of the human body always strives to maintain the temperature of the vital organs of the human body relatively stable. The so-called body temperature includes the core temperature, the skin temperature and the average temperature of the whole body.
The core temperature of the human body characterizes the temperature inside the human body and is therefore also called the internal temperature, the so-called body temperature in daily life. Both human and higher animals have constant body temperature, which varies significantly due to changes in the external environment or different activities of the human body.
The temperature of the peripheral tissue, i.e., the surface layer, including the skin, subcutaneous tissue, muscle, etc., of the human body is called the surface layer temperature. The temperature of the outermost layer of the human body surface is called the skin temperature, also called the body surface temperature. Because the skin is on the body surface, the heat sink conditions are good, and thus the skin temperature is generally less than the core temperature compared to the core temperature.

In the temperature measurement control system applying the hair identification, the method further comprises the following steps:
and the GPS positioning device is arranged at one side of the quantity analysis device and is used for providing the current GPS position of the quantity analysis device.
In addition, the precursor of the GPS is a meridian satellite positioning system (Transit) developed by the U.S. military, which was developed in 1958 and put into use formally in 1964. The system works with a star network of 5 to 6 satellites, bypasses the earth at most 13 times a day, cannot give altitude information, and is not satisfactory in terms of positioning accuracy. However, the meridian system enables research and development departments to obtain preliminary experience on satellite positioning, verifies the feasibility of positioning by the satellite system and lays a cushion for the development of the GPS. The satellite positioning shows great superiority in navigation and the meridian system has great defects in navigation of submarines and ships. The American sea, land, air and military and civil departments feel urgent need for a new satellite navigation system.
For this reason, the united states Naval Research Laboratory (NRL) proposed a global positioning network project named Tinmation with an altitude of 10000km composed of 12 to 18 satellites, and launched a test satellite each in 1967, 1969 and 1974, on which an atomic clock timing system was preliminarily tested, which is the basis of accurate positioning of GPS. The united states air force proposed 621-B plans with 3 to 4 constellation groups of 4 to 5 satellites per constellation group, all but 1 of these satellites using a slant orbit with a period of 24h, which broadcasts satellite ranging signals based on pseudo random codes (PRN), which are powerful and can be detected even when the signal density is lower than 1% of the ambient noise. The successful use of pseudorandom codes is an important basis on which GPS has been successful. The naval plan is mainly used for providing low-dynamic 2-dimensional positioning for ships, and the air force plan can provide high-dynamic service, but the system is too complex. Since the development of both systems at the same time incurs significant costs and both plans are designed to provide global positioning, in 1973 the united states department of defense united states 2 as one, led by the joint satellite navigation and positioning planning office (JPO) held by the department of defense, and the office was also set up at los angeles' air force space. The organization members are numerous, including representatives of the united states army, navy army, department of transportation, the national defense mapping office, the north convention, and australia.
The initial GPS program was born under the leadership of the united states program, which places 24 satellites in three orbits at 120 degrees to each other. There are 8 satellites in each orbit, and 6 to 9 satellites can be observed at any point on the earth. Thus, the coarse code precision can reach 100m, and the fine code precision is 10 m. Due to budget compression, GPS planning has to reduce the number of satellite transmissions and instead distribute 18 satellites in 6 orbits at 60 degrees from each other, however this solution does not guarantee satellite reliability. The last modification was made in 1988: the 21 working stars and the 3 spare stars work on 6 orbits at 60 degrees to each other. This is also the mode of operation used by GPS satellites.
The GPS navigation system is a radio navigation positioning system which is based on 24 global positioning artificial satellites and provides information such as three-dimensional position, three-dimensional speed and the like to all parts of the world all the time. The ground control part consists of a main control station, a ground antenna, a monitoring station and a communication auxiliary system. The second is a space part which is composed of 24 satellites and distributed on 6 orbit planes. And the third is a user device part which consists of a GPS receiver and a satellite antenna. The civil positioning precision can reach within 10 meters.
It is to be understood that while the present invention has been described in conjunction with the preferred embodiments thereof, it is not intended to limit the invention to those embodiments. It will be apparent to those skilled in the art from this disclosure that many changes and modifications can be made, or equivalents modified, in the embodiments of the invention without departing from the scope of the invention. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention are still within the scope of the protection of the technical solution of the present invention, unless the contents of the technical solution of the present invention are departed.
