Description of drawings
Fig. 1 is the feature operation interface schematic diagram of many cold-zones of the present invention refrigerator food method for supervising,
Fig. 2 is a refrigerator control block diagram of the present invention.
The specific embodiment
The present invention makes refrigerator increase the function of many cold-zones refrigerator food monitoring management on the basis of existing technology, by input food list and selection pot-life, make people can check the interior food record of case at any time and can be set in and remind the user when food storage life arrives.And refrigerator can be deposited the storage temperature of cold-zone according to the food information adjusting of input.Many cold-zones refrigerator comprises a plurality of cold-zones such as refrigeration, freezing, fruit and vegetable district, the temperature sensor detected temperatures is set in each cold-zone, the CPU processing unit of the temperature signal input master control borad of temperature sensor, CPU is according to the temperature of cold-zone and the set temperature value of cold-zone, and the output loading circuit control signal is controlled each cold-zone temperature.Convenient for the user is imported, on refrigerator door, embed the PDA(Personal Digital Assistant) terminal.The input block of refrigerator control system is arranged on the PDA, comprise parameter input module and instruction control module, touch the function menu that the PDA display screen starts the food management that is presented on the screen, the food policer operation of carrying out the parameter input or sending control instruction, PDA has the food memory, in order to the management information that hoards food.This memory can be by the CPU access data, and the PDA control panel is provided with the digital communication module, with refrigerator master board two-way data communication.A plurality of function choosing-items at the food management are set, as food list in food list, storage suggestion, trophic analysis, the refrigerator etc. on screen.Select different function choosing-items can enter into the next stage actions menu.
The present invention is based upon on the basis of the many cold-zones refrigerator that can independently control its temperature, and in addition, also the food monitoring form with reflection refrigerator food preservation state is the temperature that each cold-zone is realized controlling according to the food of depositing in the center; And according to depositing from date/time, whether store food is expired in the supervising refrigerator.Specifically comprise three links: 1) food is put into the cold-zone that refrigerator is fit to; 2) calculating of food storage time and date and monitoring; 3) food takes out from refrigerator.
Wherein, put into the suitable cold-zone of refrigerator at food and comprise following link: 1) input food produces current date/time, 2) search definite resting period and temperature in the food table commonly used according to input food; 3) in the food monitoring form, set up a data record.In the calculating and monitoring link of food storage time and date, comprising: 4) regularly detect the cold-zone temperature,, then start its refrigeration, freeze if be lower than best storage temperature certain limit then stop this cold-zone if be higher than best storage temperature certain limit; 5) regularly detect best holding time in current date/time and the food monitoring form, if the current time before the critical zone, then belong between safe period, as in the critical zone then for during the prompting; , then send during the expired warning through the critical zone as; Food takes out from refrigerator and comprises 6) from the food monitoring form deletion about the record of this food.
The invention will be further described below in conjunction with drawings and Examples.
Referring to Fig. 1, the various functions of carrying out the food management on the display interface of PDA, have been shown.Click respectively and can enter the next stage submenu.The title of various foods commonly used, corresponding fresh-keeping time limit suggestion and suitable storage temperature have been stored in the tabulation mode in the memory of PDA, the data that preset are listed in food list, the user can be input to the food of not listing in some tabulations in the memory, also can be by personal habits input or the fresh-keeping time limit suggestion of rewriting food.The memory of PDA has also preset the food monitoring form of a reflection refrigerator food preservation state, in order to the food preservation in input, the control refrigerator.Click 101 and enter the food list function, the food list that the PDA screen display is built-in.The user can directly choose the food title from food list, system will provide initial holding time of every kind of food and corresponding pot-life, suitable storage temperature automatically, wherein initial holding time system default is the same day, but the user also can manually rewrite, the user also can rewrite the data of storage life and storage temperature, the control temperature range that PDA presets according to each cold-zone in the storage temperature of refrigerator food and the refrigerator is judged the suitable storage cold-zone of food, above data write the food monitoring form, sort in proper order by the initial holding time of food of input.The user sets the order that whether need report to the police the newspaper phase and selects type of alarm, for example buzzing warning, the overdue food information of screen display, or, show undue food list with green with the overdue food list of red display.The data-storing of user's input starts the clocking capability piece, output alarm information when storage life expires in memory.The user also can at any time check the storage state of food by tabling look-up.
In refrigerator food list function, the user can check the food list of storage and the details of every food.Click 102 and enter refrigerator food list function, from memory, take out food monitoring form and demonstration.These function details comprise the storing temperature of the classification under institute's storage food, the time of purchase, the fate of guaranteeing the quality, suggestion etc.The user can select in the inventory of food monitoring form and delete and take out the food title that uses up.
Click 103 and enter storage suggestion function.In this function, system may regulate the design temperature of each cold-zone of refrigerator automatically according to the food species in the food monitoring form, so that food is deposited under the storage temperature of the best.Describe this functional module in detail in conjunction with Fig. 2.Referring to Fig. 2, this function relies on the refrigerator control system that comprises PDA control panel and refrigerator master board (MCU) composition to finish.Its course of work is: after PDA receives the food data of user's input, deposit in the food monitoring form, PDA judges the best storage cold-zone of food and writes monitoring form, system's supposition food is placed in storage in this cold-zone, the PDA control panel is established analog operating unit, analog operating unit carries out logical operation to the suitable storage temperature of these all foods of cold-zone, determine suitable real time temperature control parameter, when showing output this temperature control parameter is sent to MCU by the RS-232 serial line interface, MCU data in view of the above makes corresponding control to load such as magnetic valve etc., and by the physical parameter in devices such as the sensor collection refrigerator, the temperature maintenance that makes this cold-zone is in control range.Wherein, can be one of following two kinds of methods to the temperature controlled logical calculation method of cold-zone: the first, the suitable storage temperature addition of the food in the same cold-zone is averaged, as the real time temperature control parameter of this cold-zone.The second, with design temperature and the above-mentioned mean value weighted average that preset the cold-zone, this numerical value is controlled parameter as the real time temperature of this cold-zone.
The data information of people's desired nutritional of all age group that provides by the expert has been provided in the memory, has been entered the trophic analysis function and can read these information by clicking 104.Also can and be stored in the memory by PDA online download out of Memory.
