Described real-time clock generator is connected with standby power supply.
The utlity model has following technique effect:
Owing to use electronic label read-write head and this contactless automatic identification technology of electronic tag, can satisfy the needs of the real-time observing and controlling of various parameters in fruits and vegetables storage, the transportation environment, and, structure is flexible, be easy to configuration, applicability is strong, no matter is small-scale tentative introducing, and still large-scale system introduces and all can realize.And simple in structure, cost is low, can be widely used in the logistics field.
Description of drawings
Fig. 1 is the circuit diagram that is used to write down the electronic label device of preserving fruit and vegetable utilizing information.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
The circuit diagram of the electronic label device that is used to write down preserving fruit and vegetable utilizing information of the present utility model as shown in Figure 1, comprise sensor, A/D converter, calculation control unit, electronic label read-write head and electronic tag, sensor is connected with calculation control unit by A/D converter, and real-time clock generator RTC is by two-wire serial bus interface I
2C is connected with calculation control unit, and calculation control unit is connected with the electronic label read-write head by synchronous serial interface SPI, carries out radio communication between electronic label read-write head and the electronic tag.Calculation control unit is used for readout time, date data and supplemental characteristic, and by the electronic label read-write head time, date data and supplemental characteristic is write electronic tag.The real-time clock generator is connected with power supply respectively with calculation control unit.The real-time clock generator adopts DS1337, the data of sensor acquisition and transmission need the collection date and time of additional parameter simultaneously, DS1337 adopts the data of two-way two buses to transmit working method, be that chip is under the control of serial clock, receive command word or the address date that sends from calculation control unit by the serial data termination, also can give calculation control unit by data such as serial data end date of shipping, time, interrupt request singals.Sensor can be a kind of or combination in gas sensor, humidity sensor, the temperature sensor.Gas sensor can be a kind of or combination of sensor that detects the content of oxygen, carbon dioxide, ethene etc.
In actual use, can use the calculation control unit that calculation control unit and A/D converter, two-wire serial bus interface, synchronous serial interface are become one, as ATMEGA16 etc.
Power supply is chargeable secondary cell, for the power supply of whole preserving fruit and vegetable utilizing reference record system, comprising the power supply of RTC.Real-time clock generator RTC also is connected with standby power supply, and when power supply did not have electricity, standby power supply began the power supply for RTC, to prevent losing of time data.
