method of measurement and registration of temperature as a function of time and system for measuring and recording temperatures as a function of time

摘要

In a method of temperature measurement and recording as a function of time, the total measured temperatures range, within at least -10°C to 25°C bracket, is divided into measurement segments, and each segment is paired with an individual resistor-transistor logic RTL. All individual resistor- transistor logics RTL are connected to thermistor T circuit which is connected with a microprocessor M. Microprocessor M connects with external RAM. Thermistor T together with the hardware/SoC is placed at the measurement location; the signal representing the instantaneous value of voltage drop on thermistor T is directed to microprocessor M where the instantaneous value of voltage drop on thermistor T is converted to a corresponding instantaneous value of temperature; next, probing is performed by means of microprocessor M where, based on comparison, previously recorded instantaneous value of temperature is paired with an individual resistor-transistor logic RTL; next, during the measurement proper, by means of microprocessor M all resistor-transistor logic RTL are disconnected and connected again into resistor-transistor logic RTL, which were earlier paired with the measurement segment responsible for the currently measured instantaneous value of temperature, and using the total converter resolution of microprocessor M the instantaneous value of temperature in a given measurement segment is measured.
