Abstract
The invention discloses a kind of intelligent sequence reader based on digital temperature sensor DS18B20.Device is made up of microprocessor, LCD liquid crystal display screen, N*N rank matrix form digital temperature sensor straight cuttings interface module, EEPROM storage chips, setting button, lithium electricity management of charging and discharging module.Sequence number batch reading program in microprocessor, unique 64 lasered ROM sequence numbers that more DS18B20 in array possess can be read out, as a result be shown on LCD liquid crystal displays or be stored in EEPROM storage chips.Because the present apparatus employs convenient array straight cutting interface, and support hot plug.Sequence number batch quick search can be carried out, greatly reduces the query time of sequence number, improves operating efficiency.
Description
Technical field
The present invention relates to the reading of the batch of digital temperature sensor DS18B20 sequence number, digital temperature can be widely applied to
Sensor consistency is tested and revised.
Background technology
The digital temperature sensor DS18B20 of DALLAS instrument companies of U.S. production is that a kind of unibus system digital temperature passes
Sensor.Its compact, simple in construction, strong antijamming capability, it is not required to the i.e. achievable single port communication of outward element.It is particularly every
ROM includes the unique sequence numbers of 64 photoetching in sensor chip, is widely used to Distributed Multi field of temperature measurement.
And current stage, the reading for 64 lasered ROM sequence numbers of digital temperature sensor DS18B20 itself have no specially
There is equipment, be the reading for coordinating single-chip microcomputer progress sequence number using three core sensor interface sockets of manual welding mostly.And this
Although kind of a simple reading manner has been widely used, it is only capable of reading a sensor sequence number every time with this method, and operate
The cumbersome acquisition for being only applicable to a small amount of sensor sequence number.In addition to time and efforts is expended, easily produce maloperation and cause mistake
The shortcomings of misreading.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, digital temperature sensor is based on the invention provides a kind of
DS18B20 intelligent sequence reader.Person works' amount can be effectively reduced, misreading for sequence number is reduced, increases substantially
Operating efficiency.
The technical solution adopted in the present invention is：Include microprocessor, LCD liquid crystal display screen, N*N ranks matrix form numeral temperature
Spend sensor straight cutting interface module, EEPROM storage chips, button, wherein lithium electricity management of charging and discharging module, microprocessor are set
Respectively with LCD liquid crystal display screen, N*N rank matrix form digital temperature sensor straight cuttings interface module, EEPROM storage chips, set
Button, lithium electricity management of charging and discharging module are connected.During system operation, the sequence number batch reading program in microprocessor can be right
More DS18B20 in array carry out sequence number reading, are as a result shown on LCD liquid crystal displays.The sequence number read can be by battle array
Row sequence is stored in EEPROM storage chips, or is sent by RS232 serial ports to computer and carried out display reading.
Compared with prior art, the intelligent sequence number provided by the invention based on digital temperature sensor DS18B20 is read
Device.Person works' amount can be effectively reduced, misreading for sequence number is reduced, increases substantially operating efficiency.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is structured flowchart of the present invention, and microprocessor uses 15F2K32S2, EEPROM storage chips during example is implemented
Using 24C512, N*N rank matrix form digital temperature sensor straight cutting interface modules use 9*9 specifications.During system operation, microprocessor
Sequence number batch reading program in device, sequence number reading can be carried out to 81 DS18B20 in array, as a result be shown in LCD
On liquid crystal display.The sequence number read can sort by array and be stored in EEPROM storage chips, or be sent by RS232 serial ports
Display reading is carried out to computer.
The technical principle for being the specific implementation example of the present invention and being used above.According to the disclosed invention
Content, all category are using N*N rank matrix form digital temperature sensor straight cutting Design of Interface Module based on digital temperature sensor
DS18B20 intelligent sequence reader belongs to abuse.
