Description
Technical field
The present invention relates to a kind of food hygiene control-management system, the food hygiene control-management system of particularly a kind of utilization radio frequency identification (RFID).
Background technology
Along with the step of industry and commerce is accelerated, ready-made, delicatessen and favor exquisite, that diversified frozen food has been subjected to large quantities of consumers fast; Yet, because it is improper that freezing, chilled food transports the temperature control of process, cause food defrosting to destroy original pattern, mouthfeel, quality modified tone phenomenon also arranged what is more, such as prepared food food Escherichia coli content too much do not conform to the rules, food indicates not clear ... or the like problem occur one by one.
Food from produce to peddle need through factory process, vehicle transport, process such as sell stores, puts on the shelf, whether food can continue to be kept at often makes the consumer query in the safe temperature range, and the retail path can't provide the concrete data of associated temperature keyholed back plate also, when the news that goes wrong when the food hygiene quality is appeared in one's mind, also the sale to the retail path produces great impact, especially when relevant issues take place, be difficult to determine which section of production and marketing chain is out of joint.
As shown in Figure 1, after a food 10 is produced by kitchen 11, need be transported to retailer 15 via sea-freight 12, land transportation 13 and/or air transport 14, in a single day there is arbitrary process temperature keyholed back plate to make mistakes in the middle of this, promptly may cause the bad problem of above-mentioned food hygiene, therefore to how to grasp the omnidistance keyholed back plate of food hygiene, be the problem of solution that each tame dealer needs badly.
Recently, the scientific and technological evolution in radio frequency identification (RFID) field is rapid, more existing inventions are applied in radio frequency identification (RFID) device on the field of food hygiene keyholed back plate, these patents are for example: No. 490640, TaiWan, China " utilizing radio frequency to differentiate method and the electric label and the system thereof of component technology record product dynamic property ", U.S. Pat 6294997 " radio frequency identification (RFID) label " with timing and environment module, US2004/0100380 " is used to follow the trail of radio frequency identification (RFID) System and method for of food freshness ", and US2004/0041714 " radio frequency identification (RFID) temperature device and method ".
The principal character of TaiWan, China 490640 is to utilize radio frequency to differentiate the method and apparatus of component technology record product dynamic property, it includes the electric label of being furnished with sensor and the dynamic property that can determine product after label activates, this dynamic perfromance can further be processed into other dynamic perfromance, and this dynamic perfromance is the temperature of product or regularly product is made the term of life that measuring temp is derived.
The principal character of US6294997 is to utilize radio frequency identification (RFID) electric label at the dynamic property every one section specific time keeping environment, and electric label is furnished with time and environmental sensor and internal memory.
The principal character of US2004/0100380 is to use radio frequency identification (RFID) electric label record merchandise news with the freshness that predicts food in storeroom or the refrigerator or do not arrived term of life.
The principal character of US2004/0041714 is to utilize affiliated external container of radio frequency identification (RFID) electric label passback or internal temperature, can set high temperature or low temperature range.Radio frequency identification (RFID) electric label when entering radio frequency identification (RFID) reading machine read range, the wireless remote automatic charge device.
As from the foregoing, mostly these known techniques are that using wireless radio frequency identification (RFID) device removes to assist to monitor the object that it will be used, its action principle is will contain after the electric label of battery and temperature-sensing device sets through control device, each section period voluntarily or be triggered and write down each interval environment temperature or time situation.The function of this type of design is to rely on the battery module supply capability in the active electronics label to give environment sensing temperature and recording module, when in case the battery module power shortage fails again in time to find, tend to have influence on the normal record of environment sensing temperature module and recording module, what is more the data of the preceding record that can lose; In addition, the unit price of present active wireless radio frequency identification (RFID) label is still quite expensive, also greatly reduces the wish that it uses radio frequency identification (RFID) label for the dealer; In addition, owing to can't omnidistancely note down the storage temperature of food and the consumer can be inquired about easily, be to lack the guarantee of feeling at ease concerning the consumer.
