The single-chip microcomputer STC15F104W carries out address input on three address input ports A, B, C of a 3-8 decoder 7 with the model 74LS138, information represented on the 3 data lines is converted into 8 possible conditions to be output by the decoder 774LS138, output voltage is adjusted through resistor strings connected with the decoder 774LS138, namely different address input data cause different output ports of the decoder 7, and different voltage values are output through different resistors connected with each output port.

The timing method based on the photovoltaic timing label for the medical reagent and the food comprises the following steps:

first, the light-shielding tape 13 covering the dye-sensitized solar cells 14(DSSCs) is removed, and the dye-sensitized solar cells 14 absorb low-intensity indoor light and convert the light into electric energy, and provide +5V voltage to supply power to five parts of the timing device, including: the display driver comprises an STC15F104W singlechip, a decoder 774LS138, resistor strings R1-R7 connected with the decoder and a display driver integrated circuit 8LM 3914.

the selection of the timing mode is carried out through the adjustment of the tact switches 11S0, S1 and S2;

it should be noted that no matter what timing mode is selected, when the address input of the decoder 774LS138 is 111 at the beginning of operation, the output voltage of the corresponding Y7 port is 1V at the pin 5 of the display driver ic 8 through the resistor R17, and at this time, the 8 leds D0-D7 are in full bright state.

When the timing mode is selected, the single-chip microcomputer STC15F104W stops for three seconds after the timing mode is selected and outputs data address information, so that the completion of the selection process is ensured, and the error judgment of the timing mode by a circuit is prevented; the selection and timing of the tact switch 11 are shown in table 1:

TABLE 1 relationship between selection of tact switch 11 and timing mode

As can be seen from Table 1, when the timing mode of 8 days needs to be selected for timing, the switch S0 is closed, the switch S1 and the switch S2 are opened, the STC15F104W single chip microcomputer executes a clock program for timing according to the day, namely, the output of the ports P3.3, P3.2 and P3.1 of the STC15F104W singlechip or the data address information input by the A, B, C port of the decoder 774LS138 are changed once every day, the change of the address information follows the sequence of 111-, because different data output ports are connected with different resistors, the voltage at the 5 pins of the display driving integrated circuit 8LM3914 controlled by the data output ports is reduced by 0.125V at a time according to the changing sequence of the data output ports; when the voltage at the pin 5 of the display driving circuit LM3914 is reduced by 0.125V, correspondingly extinguishing one light emitting diode in the protective shell 9 according to the sequence of D7-D6-D5-D4-D3-D2-D1-D0; according to a certain extinguishing sequence, one light emitting diode is extinguished every other day, so that the function of time prompt is achieved.

Example 2: the structure of the label in embodiment 2 is basically the same as that of the label in embodiment 1, and the description of the same parts is omitted, except that the thickness of the label is 5 mm.

Example 3: the structure of the label in embodiment 4 is basically the same as that of the label in embodiment 1, and the description of the same parts is omitted, except that the thickness of the label is 8 mm.

Example 4: application example 1

Application of photovoltaic timing labels in the medical field:

in the medical field, for example, during surgery, medical staff can inject anesthetic agents into patients needing surgery to make the whole or part of the patients lose consciousness temporarily due to the treatment requirement, so that the surgery can be performed smoothly. However, depending on the requirements of the operation, the medical staff may inject the anesthetic into different parts of the patient in several times, and the time for using the anesthetic is strictly required. If a doctor observes the body surface characteristics of a patient and observes the time of a watch or a mobile phone to determine the anesthetic using time interval, the precise control of the injection time interval is difficult to realize, and therefore, the photovoltaic timing label with a plurality of time prompt functions is effectively attached to medical supplies such as anesthetic and the like.

As shown in fig. 5, before the anesthetic is used, a label is adhered to the needle tube wall through an adhesive layer 5; when the shading adhesive tape 13 covered on the surface of the dye-sensitized solar cell 14 is taken down, the power supply 12 starts to work to provide +5V voltage for the whole circuit, and the light-emitting diodes D0-D7 are all bright; then, the timing mode is selected through the three tact switches 11, when the timing mode is determined, the circuit system starts to time according to the set time, and the light-emitting diodes are also extinguished one at every set time correspondingly; for example: and simultaneously closing the switches S0 and S1 and opening S2, wherein the timing time of the timing label is 80 minutes, the timing unit is 10 minutes, namely, one light-emitting diode is turned off every 10 minutes in the timing mode, and when the light-emitting diodes are completely turned off, the timing of 80 minutes is finished, so that the effect of gradual change and multiple time prompt is achieved, and the anesthetic degraded by the medicine is prevented from being generated due to the fact that the usage time exceeds the effective usage time and even changes in the aspects of the structure, the composition, the clinical titer and the like of the medicine and the reagent are prevented from being used.

Example 5: application example 2

Application of photovoltaic timing labels in the field of food:

in the food field, in order to find out the deliciousness of food, the enjoyment period is very short, and particularly, the dairy products with short enjoyment period need to be eaten or used within a strict time range to ensure the taste and nutrition; in addition, the shelf life of some fresh foods is short, and after the shelf life exceeds the specified shelf life, components which cannot be desorbed and absorbed by a human body can be generated or decomposition and denaturation of protein can be generated to generate harmful substances, nitrite and other substances which are harmful and carcinogenic to the human body, so that the application of the photovoltaic timing label in the aspects of food safety and health is very important.

As shown in fig. 6, before the milk is unsealed, a label is adhered on the milk box, and after the light-shielding adhesive tape 13 covered on the surface of the dye-sensitized solar cell 14 is removed, the power supply 12 starts to work to provide +5V voltage for the whole circuit, and the light-emitting diodes D0-D7 are all bright; then, the timing mode is selected by three tact switches 11, when the timing mode is determined, the circuit system starts to time according to the set time, and the light-emitting diodes D0-D7 are all on, and are also turned off one by one at the set time, for example: and simultaneously closing the switches S0 and S2 and opening the switch S1, wherein the timing time of the timing label is 8 hours, the timing unit is 1 hour, namely, one light-emitting diode is turned off every 1 hour in the timing mode, and when the light-emitting diodes are completely turned off, the timing of 8 hours is finished, so that the effect of gradual change and multiple time prompt is achieved, and the condition that the human body is injured by using the milk which exceeds the shelf life is prevented.
