BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic skip channel selection setting device that can automatically select and set a skip channel.

0002

2. Description of the Related Art FIG. 3 is a block diagram of a conventional skip tuning setting device capable of skip tuning. In FIG. 3, 1 is a control panel that selects a channel or instructs skip tuning, and 2 is a microcomputer (hereinafter referred to as a microcomputer).Based on the input from control panel 1, Issues instructions to memory 3 and tuner 4. 3 is a memory for storing channel position and skip selection information, 4 is a control panel 1
This is a tuner that selects the specified channel.

Next, the operation will be explained. First, the operator uses the channel selection button in the control panel 1 to search for a channel position where he/she wishes to perform skip tuning. This tuning is performed by the tuner 4 under the control of the microcomputer 2 which receives instructions from the tuning button in the control panel 1. Next, the operator presses the skip channel selection setting button on the control panel 1. Due to this,
The channel position and skip selection information is written to the memory 3 under the control of the microcomputer 2, and the information about the channel position and skip selection is written into the memory 3, and the information about the 1
Settings for skip tuning are completed for the two channel positions. If there is another channel position that is desired to be skipped, the operator searches for and sets the channel position each time.

[Problems to be Solved by the Invention] Since the conventional skip tuning setting device is configured as described above, it is necessary to specify skip tuning for each channel position, and it is necessary to specify the skip tuning for each channel position. The problem is that the more there are, the more time and effort it takes.

[0005] This invention was made in order to solve the above-mentioned problems, and it automatically searches for an empty channel position and performs skip tuning. The purpose of the present invention is to obtain an automatic skip channel selection setting device.

[0006]

[Means for Solving the Problems] The automatic skip channel selection setting device of the present invention includes a setting start instruction means, a counter,
A tuner that selects a channel according to the number of channel positions of the counter, a means for measuring the selected electric field strength, a memory, and a memory that controls the counter and the tuner and instructs skip tuning according to the comparison result between the electric field strength and a predetermined level. and is provided with control means for writing the information into memory.

[0007]

[Operation] The automatic skip channel selection setting device according to the present invention has a counter that counts up one by one.
All channel positions can be referenced, the electric field strength is measured by the measuring means for each channel, and if the control means determines that the signal is weak, it is skipped and selected and written in the memory.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a flowchart showing an example of the operation of an automatic skip tuning setting device according to an embodiment of the present invention, and FIG. 2 is a block diagram of the automatic skip tuning setting device according to the above embodiment, which is the same or Corresponding parts are given the same reference numerals 1 to 4.

In FIG. 2, reference numeral 1 denotes a control panel serving as an instruction means for instructing the start of automatic setting of skip channel selection, and numeral 2 denotes a microcomputer that controls the automatic setting of skip channel selection. 3 is a memory that stores information on interleaved channel selection; 4 is a tuner that selects the channel of the channel position number CH of the counter 5; and 5 is a memory that stores information on skip channel selection.
” count up, the number of channel positions CH
A counter 6 is a signal measuring device serving as a measuring means for measuring the electric field strength of the channel selected by the tuner 4 and outputting the measured value.

The microcomputer 2 controls the counter 5 and the tuner 4, compares the electric field strength measured by the signal measuring device 6 with a predetermined level, and instructs skip tuning according to the comparison result. Information on skip tuning is written into the memory 3.

Next, the operation of this embodiment will be explained with reference to FIGS. 1 and 2. First, when the operator presses the skip channel selection setting button, that is, the setting start button on the control panel 1 (S1), the microcomputer 2 starts skip channel selection (S2), and sets the minimum value to the counter 5 as an initial setting. One number smaller than the number of channel positions
0” (S3).

At S4, the counter 5 calculates the number of channel positions CH as a count value under the control of the microcomputer 2.
is counted up by "1" and the channel position number CH is updated. Then, the microcomputer 2 reads the updated channel position number CH from the counter 5 (S5
) and the maximum channel position number, for example "60" (S6), and if it is larger, the process ends.

If the number of channel positions CH is less than "60", the tuner 4 selects a channel having the same channel position as the number of channel positions (S7). The electric field strength of this selected signal is measured by the signal measuring device 6 (S8), and the measured electric field strength is compared with a predetermined level, for example, 15 dB, by the microcomputer 2 (S9). It instructs not to tune into the station (S10), and if it is 15 dB or less, instructs skip tuning (S11), and writes information on the skip tuning to the memory 3 (S12). After processing S12,
Returning to S4, the above operation is repeated until the number of channel positions CH exceeds the maximum number of channel positions.

[0014]

[Effects of the Invention] As described above, according to the present invention, a channel is selected by sequentially instructing channel positions across all channels, and if the electric field strength of the selected channel is weak below a predetermined level, skipping is instructed. Since the system is configured to automatically set the skip channel selection information in the memory, it has the effect of simplifying the skip channel selection setting.
