In the above, the light detector is composed of a main board, a photosensitive sensor and a logic gate, which are connected to each other. Wherein the photosensitive sensor employs a photoresistor.
The photoresistor is a special resistor made of semiconductor materials such as cadmium sulfide or cadmium selenide and the like, and the working principle of the photoresistor is based on the internal photoelectric effect. The stronger the illumination is, the lower the resistance value is, and the resistance value is rapidly reduced along with the increase of the illumination intensity, and the bright resistance value can be reduced to below 1K omega. The photoresistor is very sensitive to light, and is in a high-resistance state in the absence of illumination, and the dark resistance can generally reach 1.5M omega. The special performance of the photoresistor can be widely applied along with the development of science and technology.
The utility model discloses use cadmium sulfide photo resistance as the core, constitute the measuring circuit of first order, when the light struck, the expression is unmanned on the sick bed body, when not having the light struck or the light intensity is more weak, expresses someone on the sick bed body, and photo resistance is great, and its one section voltage of connecting the AND gate risees, and the AND gate outputs high level, drives follow-up temperature sensing circuit work.
The control module comprises a first controller and a second controller, the first controller is connected with the heating system, and the second controller is connected with the refrigerating system.
When the temperature of the sickbed body is higher than 22-28 ℃, the refrigerating system is turned on, and is turned off when the sickbed body is cooled to 22-28 ℃; when the sickbed body is lower than 12-18 ℃, the heating system is turned on and is turned off when the sickbed body is heated to 12-18 ℃. The upper temperature limit and the lower temperature limit of the sickbed body can be changed by changing the resistance value of the variable resistor (the temperature rise is variable and the temperature drop is variable).
Furthermore, the temperature raising system comprises a variable temperature raising resistor, a positive temperature coefficient sensor, a first voltage comparator, a temperature raising relay and a hot water valve which are connected with each other; the refrigerating system comprises a variable cooling resistor, a negative temperature coefficient sensor, a second voltage comparator, a cooling relay and a cold water valve which are connected.
Wherein, the positive temperature coefficient sensor and the negative temperature coefficient sensor both adopt thermistors; and the temperature rising relay and the temperature reducing relay both adopt direct current relays.
The circuit is detected on the basis of the photosensitive resistor and the thermistor, the automatic detection device for the full nodes of the direct current relay is used, automatic detection and control of illumination and temperature can be automatically achieved, self-definition can be achieved according to the use condition, detection of main parameters of the direct current relay below the 220V grade can be automatically achieved, and a measurement data information list is displayed. When the bed is used, the working efficiency is improved, the stability is enhanced, and a user can conveniently and freely adjust the temperature of the bed quickly to obtain the optimal resting state. The device is convenient to overhaul, job stabilization, multiple functional, low cost, removes the work of frequently tearing open the line from in detection achievement, both labour saving and time saving has also reduced the maloperation risk, has stronger popularization nature and novelty.
Thermistors are a class of sensitive elements, which are classified into positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC) according to their temperature coefficients. The thermistor is typically characterized by being sensitive to temperature, showing different resistance values at different temperatures, and having the characteristics of large temperature coefficient, high sensitivity, simple structure, small volume, high resistivity, small thermal inertia and the like. A positive temperature coefficient thermistor (PTC) has a higher resistance value at a higher temperature, and a negative temperature coefficient thermistor (NTC) has a lower resistance value at a higher temperature, which are both semiconductor devices.
The alloy thermistor material commonly used for positive temperature coefficient resistors is also called thermistor alloy. The alloy has higher resistivity, and the resistance value is sensitive to the change of temperature, so the alloy is a good material for manufacturing a temperature-sensitive sensor. The thermistor alloy used as the temperature-sensitive sensor has the following performance requirements: (1) a sufficiently large resistivity; (2) a relatively high temperature coefficient of resistance; (3) has a coefficient of linear expansion close to that of the experimental material; (4) a small strain sensitivity coefficient; (5) the resistance temperature curve should have good repeatability when heated and cooled in the operating temperature interval.
Materials commonly used for negative temperature coefficient resistance include single crystal semiconductors, polycrystalline semiconductors, glass semiconductors, organic semiconductors, metal oxides, and the like. They all have a very large temperature coefficient of resistance and high resistivity, and the sensitivity of the sensors made with them is also quite high. They can also be classified into negative temperature coefficient of resistance materials and positive temperature coefficient of resistance materials according to their temperature coefficients of resistance. Within a limited temperature range, the negative temperature coefficient of resistance material a can reach-6 x 10 < -2 >/DEG C, and the positive temperature coefficient of resistance material a can reach more than-60 x 10 < -2 >/DEG C. For example, barium acetosilicate ceramic is an ideal semiconductor material with positive temperature coefficient of resistance. The two materials are widely used in the aspects of temperature measurement, temperature control, temperature compensation, switching circuit, overload protection, time delay and the like, such as manufacturing a thermistor thermometer, a thermistor switch and a thermistor thermometer, and manufacturing the thermistor switch and the thermistor delay relay error and the like by using the materials respectively.

When the temperature is higher than the set upper limit, the refrigerating system of the temperature control circuit is triggered to work, the voltage comparator of the refrigerating system judges the voltage of the upper limit of the temperature adjusted by the resistance value of the user-defined resistor and the logic voltage, so that whether the temperature is reduced is realized, when the temperature is lower than the set lower limit, the heating system of the temperature control circuit is triggered to work, the voltage comparator of the heating system judges the voltage of the lower limit of the temperature adjusted by the resistance value of the user-defined resistor and the logic voltage, so that whether the temperature is increased is realized, and the bed temperature can be kept in a proper temperature range in the circulating reciprocating manner.
