Figure 3 is a block diagram showing a display device of the food storage according to the present invention.

As shown here, the first to fourth display units 210, 220, 230, and 240 are installed in each storage compartment of the hybrid food storage having four storage compartments (not shown) and display the state of each storage compartment. In addition to performing independent load control on a plurality of storage rooms, the microcomputer 200 outputting display information to the first to fourth display units 210, 220, 230, and 240 according to the state of each storage room, and the microcomputer. It is connected to the 200 and the I2C communication method to communicate with the microcomputer 200 in a polling manner at regular intervals to receive the display information to control the operation of the first to fourth display unit (210, 220. 230, 240) And a first to fourth display controller 215, 225. 235, and 245 for displaying.

Accordingly, the first to fourth display controllers 210 sequentially by the polling method at regular intervals between the first to fourth display controllers 215, 225. 235, and 245 connected to each other by the I2C communication method in the microcomputer 200. , 220. 230, 240 to display the display information, such as the operating state of each storage room by displaying the display unit 210, 220. 230, 240 installed in each storage room.

The control method of the display apparatus of the food storage room according to the present invention made as described above will be described in detail with reference to the flowchart shown in FIGS. 4 to 5.

4 is a flowchart illustrating the operation of the microcomputer and FIG. 5 is a flowchart of the operation of the display controller.

First, the microcomputer allocates an address to the first to fourth display controllers 210, 220, 230, and 240 connected by the I2C communication method, and makes the microcomputer 200 the master, and the first to the fourth display controllers 215 and 225. 235 and 245 are all set as slaves (S41).

Thereafter, the first to fourth display controllers 215, 225, 235, and 245 are set in order, and the communication is started by outputting the allocated addresses in the order determined together with the start code in the polling method at the microcomputer 200 at regular intervals. (S42).

When the address allocated to the microcomputer 200 with the start code is output at regular intervals (S42), when an address corresponding to itself is input from the first to fourth display controllers 215, 225. 235, and 245, S51) (52) A response signal is output while switching to the communication standby state (S53).

The predetermined period is 25 msec and performs communication while polling the first to fourth display controllers 215, 225. 235 and 245 sequentially at 100 msec intervals.

As described above, only one of the display controllers 210, 220, 230, and 240 in which the start code is input communicates with the microcomputer 200, and the microcomputer 200 outputs display information according to the state of each storage room (S45). The display controller receives the input display information data, outputs a response signal, and displays the received data (S57).

While displaying the data received while communicating with the microcomputer 200, the communication is completed when a stop code is input from the microcomputer 200 (S47) (S58).

Subsequently, the start code is sequentially transmitted while transmitting a start code for the assigned address of the next display controller.

On the other hand, the microcomputer 200 transmits the display information 100 times at 100 msec intervals and displays a communication error when there is no response signal (S44) (S48). The first to fourth display controllers 210, 220, 230, 240 If there is no received data even after 100 times at 100msec intervals after the response signal is transmitted in the () and a communication error is displayed (S55) (S56).

As described above, according to the present invention, as the operation panel for controlling each storage compartment of the food storage compartment having a plurality of storage compartments is installed in each storage compartment, a display unit for displaying an operation state of each storage compartment is independently provided in each storage compartment and displayed. There is an advantage that can be displayed while communicating with the display control unit of each storage room while circulating at regular intervals by being connected by I2C communication between the control unit and the microcomputer for load control.
