Description

  The present invention relates to a scanning function in a receiver.

The scan function of the receiver is a function for sequentially receiving a predetermined frequency range set in advance or a predetermined plurality of channels set in a memory in advance.
In such a scan function, when a signal is sensed, the scan is temporarily stopped or a sensed signal is detected each time depending on preset scan pause conditions and scan resume conditions. Temporarily stop scanning until it disappears.

  If you do not want to hear the signal of the frequency or channel that you feel, every time the scan operation temporarily stops at that frequency or channel with the scan function, dial operation etc. to move to the next frequency or channel There was a problem that it was annoying because it was necessary to perform.

As described above, there is a case where it is desired to operate such that a specific frequency or a specific channel is excluded from the scan target, and the scan is skipped to receive the next frequency or the next channel.
For this purpose, some have a scan skip function for skipping a specific frequency or a specific channel registered and specified in advance in a skip memory.
Such a scan skip function, for example, if a frequency or channel that does not need to be received is registered as a skip target in advance (skip registration), even if a signal of the frequency or channel is received during a scan operation, If registered, the scan operation is skipped to the next frequency or channel without stopping the scan operation and the scan operation is continued. (See Patent Document 1)

The scan function includes a scan skip function in each of the following modes.
In the scan (program scan) in the VFO mode, the frequency designated to be skipped is automatically excluded from the scan range.
In the memory mode scan (memory scan), the memory channel designated to be skipped is automatically excluded from the scan target.
In the scan in the digital repeater mode, the designated repeater is excluded from the scan target.

Japanese Patent Laid-Open No. 7-122975

By providing the scan skip function as described above, the conventional scan function can be used conveniently.
However, according to such a scan skip function, skip registered frequencies and channels are always skipped until a predetermined operation for canceling skip registration is performed. The problem of having to occur occurs. The operation of canceling the skip registration is troublesome, and if it is forgotten to cancel the skip registration, it is always skipped, so that it is misunderstood as if there is no signal that can be received at that frequency or channel.

  An object of the present invention is to realize a function of skipping a frequency or channel desired to be temporarily skipped for a predetermined period by a simple operation during a scan operation.

  According to the present invention, it is possible to skip a frequency or channel to be skipped temporarily during a scan operation by a simple operation for a certain period. Furthermore, after a certain period of time has elapsed, automatically canceling registration as a skip target and returning it to the scan target eliminates the need to be aware of canceling skip registration and prevents forgetting to cancel skip registration. The effect that it can be obtained.

It is a block diagram of the receiver which concerns on this invention. It is a flowchart explaining the scan skip function in the said receiver. It is a flowchart explaining the temporary skip registration process in the said receiver. It is a flowchart explaining the time measuring process in the said receiver.

  Hereinafter, a receiver according to the present invention will be described in detail with reference to FIG. 1 showing a block diagram of the first embodiment and FIGS. 2, 3, and 4 showing flowcharts.

In FIG. 1 showing the configuration of a receiver having a scanning function according to the present invention,
Reference numeral 1 denotes the receiver, which includes a receiving unit 2, a low frequency processing unit 3, a frequency generating unit 4, a control unit 5, and an operation unit 6.
The receiving unit 2 has a function of receiving, amplifying and demodulating a signal having a frequency specified by a frequency generating unit 4 described later.
The low frequency processing unit 3 includes an amplification circuit that amplifies the demodulated reception signal at low frequency, a speaker that outputs sound, and the like.
The frequency generation unit 4 is configured to generate a frequency of a signal to be received by the reception unit 2 by a control signal from the control unit 5 described later and to input the frequency to the reception unit 2.
The control unit 5 includes a storage unit such as a CPU and a memory 51, and is configured to systematically control each unit of the receiver 1.
The operation unit 6 includes an operation dial, an input switch, a display panel having a touch panel function, and the like, and inputs operation information for designating operations of each unit of the receiver 1 through the control unit 5. The operation status (status information such as frequency and signal intensity) of each part of the receiver 1 is displayed via the control unit 5.

The memory 51 includes various information memory areas such as a basic skip memory 511 and a temporary skip memory 512. As the memory 51, a nonvolatile memory such as a flash memory and a volatile memory such as a RAM are used.
In the basic skip memory 511, a frequency and a memory channel that are always skipped are written. It is stored in the non-volatile memory so that it is retained even when the receiver 1 is turned off.
In the temporary skip memory 512, a frequency and a memory channel to be temporarily skipped are written as needed, and are deleted after a predetermined holding time has elapsed after being written. It is not held when the receiver 1 is turned off.

The control unit 5 is provided with a time counter 52 capable of individually measuring a plurality of elapsed times.
The time counter 52 measures the elapsed time since it was written to the temporary skip memory 512 and deletes it from the temporary skip memory 512 when a predetermined holding time has elapsed.

The scanning function in the receiver 1 having the above configuration will be described with reference to the flowchart shown in FIG.
First, when a predetermined operation is performed in the operation unit 6 to activate the scan function,
In step S1, after initialization processing, reception starts from the first frequency or channel of the scan range. In the initialization process, the temporary skip memory 512 and the time counter 52 are all cleared (no storage state).
In step S2, the basic skip memory is referenced to check whether it is registered in the basic skip memory. If it is registered, the process skips to step S10 and proceeds to scan. If it is not registered, Proceed to step S3.
In step S3, the temporary skip memory is referenced to check whether or not it is registered in the temporary skip memory. If it is registered, the process skips to step S10 and proceeds to the scan and is registered. If so, the process proceeds to step S4.

In step S4, the intermediate frequency signal, status information, etc. of the receiving unit 2 are monitored to check whether any significant signal is received (with a feeling of presence) or not (without a feeling of feeling).
If there is no feeling of sensation, the process proceeds to step S10, the frequency generator 4 is controlled, and the frequency or channel to be received next in the scan range is set in the receiver 2, and the process proceeds to step S2. Return.
If there is an impression, the process proceeds to step S5.

In step S5, the scanning operation is temporarily stopped, and the demodulated low frequency signal is output from the speaker.
In step S6, it is checked whether or not a predetermined operation for registering the sensed frequency or channel in the temporary skip memory has been performed. If it has been performed, the process proceeds to step S7 to perform temporary skip registration processing. I do.
If the predetermined operation is not performed, the process proceeds to step S8.
In step S8, the process returns to step S6 until the fixed stop time elapses and is repeated, and after the fixed stop time elapses, the process proceeds to step S9.

In step S9, the scanning is temporarily stopped, the process proceeds to step S10, the next frequency or channel is shifted, and the operation from step S2 is repeated.
In step S10, when scanning to the end of the scanning range is performed, scanning is performed again from the first frequency or channel of the scanning range.

Registration Process to Temporary Skip Memory in FIG. 3 The step S7 will be described in more detail with reference to the flowchart in FIG.
As shown in FIG. 3, in step S71,
In addition to performing registration processing for writing to the temporary skip memory, in step S72, time measurement is started by a time counter corresponding to the information related to the registered frequency or channel, and the process proceeds to step S9 in the flowchart of FIG.

The timing process after the timing is started in step S72 will be described with reference to the flowchart of FIG.
In step S711, the time counting by the time counter corresponding to the information related to the registered frequency or channel is started,
In step S712, the time counting process is continued until a predetermined holding time has elapsed in the corresponding time counter,
In step S713, after a predetermined holding time has elapsed, the timing processing by the corresponding clock counter is terminated, and the information on the registered frequency or channel is deleted from the temporary skip memory, and the registration is performed. Exit without leaving.
The flowchart of FIG. 4 proceeds in parallel with the progress of the flowchart of FIG.

Table 1 shows an example of a temporary skip memory and a time counter.

The storage process to the temporary skip memory is as follows, for example.
If a predetermined operation is performed while the scan operation due to the signal input is paused, the sensed frequency during the pause is stored in the temporary skip memory in the case of a program scan by VFO. At the same time, the corresponding time counter is cleared and the scan is advanced to the next frequency.
If the memory mode scan is in progress, the sensed channel number being paused is stored in the temporary skip memory, and at the same time, the corresponding time counter is cleared, and the scan is transferred to the next memory channel. Proceed.
In the VFO mode, the write registration process to the temporary skip memory is performed as shown in No. 1 of Table 1. 1 to No. 2, No. 3. Write and register in order. In the example of Table 1, 433.200 is written 90 seconds ago and 433.260 is written and registered 10 seconds ago.
If all the temporary skip memories have already been written at the time of the write registration, the oldest No. 1 is deleted and No. 1 is deleted. 2-No. 5 information, the counter value of the time counter, 1-No. No. 4 was shifted to No.4. Write to 5 and register.

The timing process is performed as follows, for example.
The count value of the time counter of the temporary skip memory is incremented at regular time intervals (for example, every second).
Therefore, when 3 seconds elapse from the state of Table 1, for example, No. 1 is 93 seconds, no. 2 becomes 13 seconds.
When a predetermined holding time set in advance (for example, any of 5 minutes, 10 minutes, and 15 minutes can be selected), the information of the oldest memory (No. 1 in this case) whose time has passed is deleted. , No. No. 2 and later information. Shift to 1 or later.

Explanation of scan skip processing In scan skip processing in VFO mode,
In addition to the conventional operation of skipping the frequency corresponding to the frequency information registered in the basic skip memory, the frequency corresponding to the frequency information registered in the temporary skip memory is also skipped.
In scan skip processing in memory mode,
In addition to the conventional operation of skipping a channel corresponding to the channel information registered in the basic skip memory, a channel matching the channel number registered in the temporary skip memory is also skipped.
In scan skip processing in digital repeater mode,
In addition to the conventional operation of skipping repeater corresponding to the repeater information registered in the base skip memory, also skips repeater that matches the channel registered in the temporary skip memory.

As described above, according to the receiver, it is possible to skip a frequency or channel to be temporarily skipped during a scanning operation by a simple operation for a certain period. By automatically canceling skip registration after a certain period of time and returning it to the scan target, there is no need to be aware of canceling skip registration, and it is possible to prevent forgetting to cancel skip registration. It is done.
