The present invention relates to a method for displaying an operation state in a composite remote control, and more particularly, to a method for displaying an operation state of a composite remote controller for controlling an operation state when receiving and recording information or outputting recorded information of an existing remote controller.

In general, if you want to control household appliances or a certain system by using a remote controller, put a remote controller according to the product and use a dedicated infrared transmitter circuit in the transmitter of the remote controller to generate and send a special code according to the type and function of the product. In the system, the receiving code of the system was recognized to perform the desired operation by the receiving part of the system. Recently, the function of the remote controller is gradually complicated by the system construction that is complicated with the diversification of the functions of home appliances, and by the selection switch on the remote controller. It is possible to control 2-3 models from one model. However, since the various types of remote controllers generate and transmit only codes for special companies, there is a limitation element that cannot be used if the transmitter and receiver do not match, and the system to be controlled by the remote controller is not a single company product. If manufactured by two manufacturers, there was a problem of using a complicated remote control for each product to control each product.

In order to solve this problem, a composite remote controller can input a code of a remote controller used in each product to a single remote controller and control a plurality of products by a single remote controller during system control.

The combined remote controller receives an infrared input unit 5 which receives codes generated by the other remote controllers from the outside as input signals, detects and amplifies them, and stores a program and inputs each of the codes inputted through the infrared input unit 5 as shown in FIG. Memory 6 for storing the code information for all products of the company according to a series of structures, and when outputting the stored code to control the system when the input signal is stored in the appropriate location of the memory (6) The key matrix 3 selects a position, selects a function, and indicates whether the signal detection fails or succeeds by distinguishing the input mode and the output mode, and each time the signal is output in the output mode, the data to be output is stored in the memory ( 6) receiving the code data outputted from the display unit 2 and the infrared input unit 5 indicating whether or not there is a signal; The microcomputer stores the memory 6 at the location, reads the corresponding control code data of the memory 6 and outputs the data, and outputs the corresponding data to the indicator lamp so that the user can check the status according to each control signal generation and data input / output. (1), a mode switch 8 for mode selection, and an infrared ray emitting unit 4 generated by converting an electrical signal for controlling each product of each company generated by the microcomputer 1 into an optical signal. do.

The memory 6 includes a ROM in which a program is embedded and a RAM in which random data is stored.

The display of the conventional display unit 2 of FIG. 1 is composed of a plurality of light emitting diodes so that only the corresponding light emitting diodes emit light for the corresponding function so as to know the state. However, since the composite remote control has a plurality of functions, there are limitations in installing all the light emitting diodes in order to select all the functions and display the status according to the functions.

Accordingly, an object of the present invention is to display when the ROM or an external signal for each key outputs the data of the memory stored in each of the keys using a minimum display device having a different color in displaying the operation state of the composite remote controller. In order to display the command status when recording the signal of the remote controller and the LED, it has a plurality of functions with ON / OFF or Blinking status, so all LEDs should be installed to select all functions and display the status according to the functions. There is a limitation and the way to present it.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 shows the mode switch 8 and the display unit 2 of FIG. 1 according to the present invention in detail. In FIG. 2a, (a) is a use mode for outputting data, and (b) is external. It is a learn mode that can receive a signal, and (c) is a company mode that outputs the compressed remote controller data of the main product as the original signal inside the microcomputer. 2B shows an example of the installation of the light emitting diodes of three colors of yellow (Y), green (g), and red (r), which informs the operation state of the three-stage mode switch and key metrics.

3 is a flow chart according to the present invention, the first process of initializing the system, the second process of setting the standby mode, the third process of checking the mode switching state, and the user and the device in the third process And a fourth step of displaying a processing state of the basic functions of the user and the company product in the product mode, and a fifth step of displaying a processing state of the run function in the run mode in the third process.

4 is a detailed flowchart of the fourth process of FIG. 3 according to the present invention, the first step of calculating points, the second step of checking whether valid data is available from the point calculation data in the first step, and the second step. When the data is not valid data in the step is displayed as a red light and the data is valid in the second step is output to the third step of displaying a green light.

5 is a detailed flowchart of a third process of FIG. 5 according to the present invention, and a signal input standby display process of displaying a yellow light and receiving a key input to drive a green light for a signal input standby state, and the signal input standby display When the signal input of the process is completed, the red signal input standby display process of driving the green light to the standby state of the re-signal input according to the key input by driving yellow and green lights, and the first time The display of the second signal is performed by comparing the second signal and distinguishing colors according to the state of the input to blink twice.

Therefore, a specific embodiment of the present invention will be described in detail with reference to FIGS. 1-5, the present invention is realized by the program control of the microcomputer (1) in accordance with the state of the mode switch 8 as shown in FIG. The operation states of the processing lamps in (a) and company mode (c) and in the run mode (b) in accordance with the third to fourth flowcharts will be described in detail.

In FIG. 3, the initial state of the initial power is applied, and the initial state of the microcomputer 1 is designated (3a), and the standby state is set for low current consumption (3b). When interrupt occurs due to switching (3cl), the state of mode switch 8 in the present state is checked (3c2) and each process is performed. (3d, de)

This is handled by the use of the process (3d) of FIG. 3 above and the data output flow chart (FIG. 4) in own mode. If there is no stored data, an error is displayed (4d). If there is stored data, the green light of the display unit 2 is displayed together with the data output 4C (4e). In the run mode (3c2), it is a mode for receiving an external signal and storing it as compressed data, and displays a key input or a signal input request as an operation state.

First, the display unit 2 displays yellow (Y) or the like to indicate the run mode (5a) and waits until (5b1) when a key for storing a signal from the outside is pressed. When the key is pressed, the status of the signal input function is notified (5b2), and the display unit 2 displays the green light until the signal is completed (5c1). When the signal is completed, the yellow and green light of the display unit 2 is displayed as a display (5c2) and waits until the same key is pressed again (5d1).

Similarly, the process (5d2, 5e) performs the same operation as the process of (5b2, 5c1), and correct information (5h), inability to input (5g), different information on the signal input twice in the process (5f). Each operation state is displayed by dividing into three states (5j).

When the display function is shown as a table, it is shown in Table 1.

TABLE 1

In Table 1 above, 0 remains on or off and "0" is marked as blinking. In other words, when the input information is not available in step (5F), the yellow and red lights of the display unit 2 are blinked twice with 2HZ in step (5g), and when the correct information is displayed, the yellow, green, etc. of the display unit 2 are turned off. Blinking twice with 2HZ and if the microcomputer 1 checks whether the memory is full when the information is different in step 5f, the yellow, green, and blue light emitting diodes of the display unit 2 are twice with 2HZ in step 5i. Blink and blink red twice with 2HZ when not over memory.

As described above, the data output state of the stored memory of the external signal can be displayed in various colors, and when the signals of the remote controller are input to the composite remote controller, the different colors can be differently blocked to clearly distinguish the functional state of the composite remote controller. There is an advantage.
