Abstract

Provided is a temperature recording apparatus, comprising a master control module, a temperature collecting module, a clock module, a temperature display module, and a 485 bus module. The temperature recording apparatus is characterized in that: the master control module is connected with the temperature collecting module, the clock module, the temperature display module, and the 485 bus module respectively; the master control module collects temperature data via the temperature collecting module; the master control module adds time point data via the clock module; the local data is displayed upon the temperature display module; and the temperature and time data are transmitted to a host computer via the 485 bus module, thereby providing the host computer with grounds for further analysis and processing.

Description

Temperature recording unit
Technical field
The utility model relates to a kind of temperature measuring equipment, especially temperature recording unit .
Background technology
In Measurement and Control System, particularly unattended TT&C system often need write down some special temperature data and time of occurrence thereof.These data are significant to the performance evaluation and the normal operation of TT&C system.Traditional data record be at a distance from the time sampling or timing sampling, can only record data, the concrete time that can not record data occurs, this brings very big inconvenience to TT&C system.
Summary of the invention
In order to solve the shortcoming of above-mentioned conventional temperature surveying instrument, the utility model provides a kind of temperature recording unit, adopts clock chip record thermometric time point, carries out the transmission of data through remote bus mode.
The utility model solves the technical scheme that its technical matters adopted: temperature recording unit; Comprise main control module, temperature collect module, clock module, temperature display module, 485 bus modules; It is characterized in that main control module is connected with temperature collect module, clock module, temperature display module, 485 bus modules respectively.Main control module is through temperature collect module collecting temperature data; Through clock module joining day point data; On the temperature display module, carrying out local data shows; And through 485 bus modules with the temperature and time data transmission in host computer, the foundation of further analyzing and processing is provided for host computer.
The beneficial effect of the utility model is, added thermometric temporal information, is convenient to analyzing and processing and excavation to data, has higher utility .
Description of drawings
Fig. 1 is the theory diagram of the utility model; Fig. 2 is the electric structural drawing of the utility model.
Embodiment
In Fig. 1; Temperature recording unit; Comprise main control module 1, temperature collect module 2, clock module 3, temperature display module 4,485 bus modules 5, it is characterized in that main control module 1 is connected with temperature collect module 2, clock module 3, temperature display module 4,485 bus modules 5 respectively.Main control module 1 is through temperature collect module 2 collecting temperature data; Through 3 joining day of clock module point data; On temperature display module 4, carrying out local data shows; And through 485 bus modules 5 with the temperature and time data transmission in host computer, the foundation of further analyzing and processing is provided for host computer.
In Fig. 2; Clock module 3 adopts DS1302; Be a high-performance, the low-power consumption of American Dallas company, the real-time clock of band RAM, it can to year, the moon, day, week, the time, branch, second timing, operating voltage range is 2.5 V~5.5 V.Adopt 3 line interfaces and CPU synchronous communication, there is the RAM register that is used for interim store data of one 31 * 8 bit DS1302 inside.DS1302 is used for the timing of data recording, particularly writes down some special data point, simultaneously record data and the time that these data occur.This record is to long continuously TT&C system result's analysis and the abnormal data cause investigation to occur significant.DS1302 has two power supplies, and wherein, VCC2 is a standby power supply, and it is connect rechargeable battery, avoids having a power failure suddenly and causes the out-of-work problem of clock.DS1302 by VCC1 or in the two than the power supply of large power supply.AT24C16 is a kind of EEPROM that does not possess encryption function, is 16 K positions (2 * 8 Kbit), and the byte address space is 0~2 047.Storage organization is simple, has only two kinds of operating functions of read-write, mainly deposits the not high data of confidentiality.DS18B20 is the sensor of the 1-Wire digital intelligent integrated temperature of American Dallas company release.Compare with other temperature sensors, DS18B20 has following characteristic: unique 1-Wire interface mode; A plurality of DS18B20 can be connected in parallel on the signal line, realize multi-point temperature measurement; Need not any peripheral cell; Temperature-measuring range is-55 ℃~+ 125 ℃; The optional 12 bit digital quantity precision of measurement result, resolution is 0.625 ℃.Single chip computer AT 89S51 inquires about DS1302, after timing arrives, starts DS1820 and begins inversion temperature and read temperature, and the temperature data of gathering is sent into the AT24C16 storage.Consider from low-power consumption, close demonstration usually.When needing display message, activate, take turns demonstration time and Temperature numerical through 6 LED by button AN, time showing hour, divide, second; Temperature shows the temperature value with 2 decimals, and its temperature-measuring range is-55 ℃~+ 125 ℃, and most significant digit shows "+", "-".System communicates by letter with PC through RS-485 interfaces, realizes the storage and the processing of temperature data, and some writing time is set.The 7th of the control register of DS1302 is write-protect, thus before writing data, should it be closed, and after write data finishes, it is enabled.Can communicate by letter with TR the writing time of TR through the PC machine, changes time point.Writing time, point deposited among the RAM of DS1302.During system works, the current time of single-chip microcomputer inquiry DS1302 is if arrive the temperature survey time; Then begin to start DS18B20 and carry out temperature transition; Read temperature value, it is write among the AT24C16, accomplish the recorded and stored in " year, the moon, day, time, branch, temperature value "; Get into dormancy, wait for that timing wakes single-chip microcomputer again up.
