Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the block diagram of the utility model refrigerator temperature registering instrument first embodiment;
Fig. 2 is another frame diagram performance of Fig. 1.
Embodiment
Shown in Fig. 1 to 2, in refrigerator temperature registering instrument first embodiment of the present utility model, the refrigerator temperature registering instrument comprises that the temperature sensor of surveying refrigerator temperature, the storage device of storage detection refrigerator temperature data, the display device of display refrigerator temperature reach the back-up source that the reserve electric energy is provided for described storage device, described refrigerator temperature registering instrument also comprises the control device of controlling the freezer compressor rotating speed according to the refrigerator design temperature automatically, is provided with connecting circuit between described control device and described temperature sensor, storage device, display device, the back-up source.
Wherein, display device comprises digital display tube and LED light.Display device can the present temperature of display refrigerator.In order to set date and temperature and writing time in use at interval, be provided with the input media of input setting data at the refrigerator temperature registering instrument.Input media can select to import button.
In order to write down refrigerator, in storage device and control device, be provided with level converter in the temperature of each time.By control device the temperature data of temperature sensor is passed to storage device then and store.Storage device can be selected SD card or portable hard drive or mini SD card or portable hard drive or other memory device.The data of described storage device record are the data of Windows system energy direct reading.
When the external power down circuitry, for the data of reservation record, in the refrigerator temperature registering instrument, be provided with back-up source, back-up source can be selected farad capacitor or lithium battery or accumulator.
For the ease of the use of each device of control, control device can be selected MCU.
This novel being described below:
In present embodiment, this registering instrument synthesizes one with temperature control, real time temperature record, the 12V/24VDC input, and adopting the SD card is storage medium, deposit real-time temperature data in the SD card, and can read the temperature data in the SD by the board software of Windows operating system.Thereby do not need other install software.Can carry out temperature control to refrigerator simultaneously,, regulate the rotating speed of compressor automatically, make its temperature inside the box keep constant, and reduced power consumption, improve the efficient of complete machine according to current refrigerator temperature.
By pressing key assignments, the temperature inside the box can be set, show ℃/°F, the state of cell voltage protection point, current date, time, SD card, display device is a charactron.
This registering instrument also has the error diagnostics function, can be which kind of fault by the number of times announcement user of panel leds flicker.
If refrigerator is in work, power down suddenly can not destroy the data in the SD card, and when switching on once more, the state when automatically restoring to task (power-failure memory).Annotate: when outage, date, time are still in operation.
This novel use is as follows:
If system has detected the SD card and has inserted, with the temperature inside the box of every 10S collection, current time, when collecting 32 groups of data, deposit in the SD card, the file (filename is generated automatically by system) of a newly-built 16KB of while, when being filled with 16KB, system can rebulid the file of a 16KB again, file of circulation storage has 1021 row, the just temperature datas of 1021 points at most so always.If sudden power or shutdown in work, system will stop to gather, and carry out power down protection immediately and will handle (by the back-up source power supply), in order to avoid damage the data of SD card.
In the time of need taking off the SD card, should pull out power supply earlier, take out the SD card, need to insert the SD card, should insert the SD card earlier, in energized.
The expression of filename: the form of filename is current date+sequence number, as 090525a, 090525b, represents first file and second file on May 25th, 2009 respectively, supports 26 files at most in one day, and just sequence number is from a ~ z.
Native system will produce 9 files in one day under continuous working, maximum can be held 62080 files, just supports the data storage in 18 years.Calculate by 26 files of maximum generation in a day, also can store the data in 6 years.
Data in the SD card can be opened by the board software of Windows, and the data layout in the file is seen Appendix.
An annex that produces during below for this novel use:
The form that the data of each file are deposited in the SD card
