Description
Technical field
The present invention relates to temperature detection technical field, and in particular to a kind of multi-channel temperature measurement system of high-tension line single-chip microcomputer
System.
Background technology
In the living environment of the mankind, temperature plays extremely important role.No matter where you live, and what is engaged in
Work, be not turned on dealings with temperature all the time.Since the industrial revolution of 18th century, whether industrial development is to that can grasp temperature
There is absolute contact.In metallurgy, electric power, steel, petrochemical industry, cement, glass, medicine etc. industry, it may be said that almost 80% work
Industry department all has to take into account that the factor of temperature.Thus temperature advances the hair of temperature sensor for industrial so important
Exhibition.
Sensor main will substantially have passed through three developing stage：
Simulate integrated temperature sensor.The sensor be made of use silicon semiconductor integrated technique, therefore also known as silicon sensor or
Single slice integration temperature sensor.Such a sensor has function single (only measurement temperature), temperature measurement error is small, price is low, response
Speed is fast, long transmission distance, small volume, micro energy lose etc., is adapted to remote temperature measurement, temperature control, it is not necessary to carry out gamma correction, outside
Enclose circuit simple.It is at present at home and abroad using the most universal a kind of integrated sensor, typical products have AD590,
AD592, TMP17, LM135 etc.；A/D conversions are further comprises in some enhanced Integrated Temperature Contriver Circuits (such as TC652/653)
Device and the program being cured, this has some similarities with intelligent temperature sensor.But its self-organizing system, during work not by
The control of microprocessor, this is the main distinction of the two；Intelligent temperature sensor (also known as digital temperature sensor) is in 20 generation
Record what the mid-90 came out.It is the crystallization of microelectric technique, computer technology and automatic test technology (ATE).Intelligent temperature
Spend sensor internal and all include temperature sensor, A/D converter, signal processor, memory (or register) and interface circuit.
Some products also band MUX, central controller (CPU), random access memory (RAM) and read-only storage (ROM).
The characteristics of intelligent temperature sensor is can output temperature data and related temperature control amount, the various microcontrollers (MCU) of adaptation；
And it is to realize test function by software on the basis of hardware, and its intelligence degree also depends on the exploitation of software

Property, exploitation virtual-sensor and network sensor, develop the high-tech direction such as monolithic temp measuring system and develop rapidly.
With the progress and the development of industrial technology of society, people increasingly pay attention to temperature this factor, many products pair
Temperature requirement is strict.Existing market is primarily present two kinds of temperature measuring instruments of single-point and multiple spot.Instrument is surveyed for single-point temperature, mainly
Using traditional simulation integrated temperature sensor, wherein it is again high with the measurement accuracy of the sensors such as thermal resistance, thermocouple, measure model
Enclose big, and obtained universal application.Such a product temperature-measuring range is mostly between -200 DEG C -800 DEG C, resolution ratio 12, most
Small resolved temperature is between 0.001-0.01.LED display module is carried, 4 to 16 are shown.Some instrument also have
Store function, can store hundreds of to thousands of groups data.The need for such instrument can meet unique user spot measurement well.But
Spot measurement has temperature information transmission not in time, the characteristics of precision is inadequate, be unfavorable for Industry Control person timely according to temperature change
Make decision.Multipoint temperature measuring instrument, the relative measurement accuracy with single-point has a certain distance, although realize multi way temperature
Observing and controlling, it is but expensive.
Under such form, exploitation one kind can measure multiple spot simultaneously, and real-time is high, accuracy is high, can be comprehensive
The measuring system for closing processing multi-point temp information is just necessary.
