The hybrid food storage of the present invention made of the above-described configuration is equipped with a multi-purpose room for storing wine as well as kimchi and vegetable fruit, so that it can perform the function of the food storage together, separate wine for wine storage It is possible to reduce the economic burden by eliminating the need for storage, and the layout structure of each open or drawer storage container for kimchi, vegetables, fruits, and wines is convenient for the user. There is an advantage that can upgrade the merchantability.

As described above, the operation panels and the display apparatuses 101, 102, 121, and 131 are installed in the first to second storage bins and the left to right drawer bins, respectively, so that the operating states of the first to second bins and the left to right drawer bins are changed. In addition to the operation through the operation panel, in order to display through the display device, the microcomputer and I2C communication method are connected to each other. The operating status of the storage room will be displayed.

In this case, when the control panel receives a key input by a cap sensing method of a programmable system on chip (PSoC) device, the cap sensing value is changed due to the influence of the external environment, thereby changing the sensitivity of the key input.

That is, since the capsense method of the PSoC device made as shown in FIG. 3 has a short time for charging and discharging the capacitor C when there is no key input, the period of the sawtooth wave output from the comparator Comp is shortened. The set value of the timer of the PSoC device is expressed as a small value, and when there is a key input, the sawtooth wave is output from the comparator (Comp) because the inherent capacitance value of the capacitor (C) and the capacitance value by the finger are added to increase the time for charging and discharging. Since the period of is increased, the timer setting value of the PSoC device is represented by a large value.

Therefore, the key input is determined as the key input when a timer setting value having a predetermined difference from the timer setting value in the normal state is input.

However, in case of using PSoC device, in addition to key input, temperature sensor value or switch input value is connected through external input port through a number of external inputs. There is a problem in that the key input is not normally performed according to the influence on cap sensing for the key input by receiving the component.

The present invention has been made to solve the above problems, an object of the present invention is to set the operating state of each storage compartment of the food storage having a control panel by the capsensing method of the PSoC device respectively installed in a plurality of storage compartments In case of key input on the operation panel, all external input ports of the PSoC device are set as output, and then key input is accepted to prevent key input and external input at the same time. It is to provide a key input method of the food storage to be made.

The present invention for achieving the above object in the key input method of the food storage through the operation panel by the cap sensing method of each of the PSoC device installed in a plurality of storage rooms, after setting all the external input ports of the PSoC device as an output Set the input to any one of the external input ports to receive the external data, reset the output to the output, and perform a process of detecting key input for a predetermined time, and then the above processes are sequentially performed for the other external input port. Repeatedly proceeds for all external input ports.

In the present invention, the external data is a temperature sensor value or a plurality of switch input values.

According to the present invention, the external input port is set as an output so that key input and capacitive input of the PSoC device and external data through the external input port of the PSoC device are not simultaneously performed. In addition, by setting the external input ports as inputs one by one, the data input and output settings and the key input detection process are operated alternately so that stable data input can be achieved because no external data input occurs during key input detection. do.

The present invention relates to a key input method in the operation panel (101, 102, 121, 131) by the cap-sensing method of the PSoC device respectively installed in a plurality of storage chambers in the PSoC device, the temperature sensor value or multiple It receives the switch input value of and communicates with a microcomputer (not shown) to control the food storage.

At this time, in order to prevent external data input and key input detection by the external input port at the same time, first, all external input ports of the PSoC device are set as outputs so that external data is not continuously input through the external input port (S41). ).

By setting all external input ports as outputs as described above, key input detection is performed so that capturing errors due to the input of external data do not occur (S42).

When key input is detected for a predetermined time, the key value is accepted as an input.

Thereafter, after the key input detection is performed for a predetermined time, external data, that is, a temperature sensor value or a plurality of switch input values are sequentially input by setting one of the external input ports as an input sequentially (S43) (S44). ).

As described above, only one external input port is set as an input, and after receiving external data, the controller resets the output to output again and performs key input detection again (S45).

After the key input detection is performed for a certain time, another external input port is set as an input again, and the external data is input and reset again to the output. Then, the key input detection is repeatedly performed alternately. .

In this way, the process of setting any one external input port as an input, receiving external data and resetting it as an output, and performing a key input detection for a predetermined time alternately repeats the steps sequentially for all external input ports. It is operated so that input of data and detection of key input are not performed at the same time.
