Description

  The present invention relates to a wireless communication apparatus having a scanning reception function, and more particularly to a wireless communication apparatus that can freely set a reception channel to be scanned and an order.

In a communication system in which a plurality of wireless communication channels are set, a scanning reception function is often used for reception while sequentially switching each wireless communication channel. The scanning reception function is frequently used not only in commercial radio communication systems used for disaster prevention, police, security, transportation, but also in leisure radio communication systems such as amateur radio and personal radio.
In the initial scanning reception of the wireless communication device, for example, as shown in FIG. 6, taking a system including CH1 to CH100 as wireless communication channels as an example, the entire 100 channels are grouped into one group (hereinafter referred to as “bank”). Therefore, it was impossible to selectively receive only a specific bank.

  Therefore, the same applicant proposed Japanese Utility Model Publication No. 7-37385 (Patent Document 1) as an improved device. This is because the communication channel 100 shown in FIG. 6 is subdivided into five banks A, B, C, D, and E, as shown in FIG. 7, for example, as shown in FIG. -It can be separated freely. In this way, if any related wireless communication channels are grouped and only a desired bank is selected for scanning reception as shown in FIG. 8A, for example, unnecessary wireless communication channels are obtained. No need to scan. Further, it is more convenient if a plurality of banks are combined or separated into a new bank (or group) and scanned as shown in FIG. Note that group A (GRA), group B (GRB), and group C (GRC) in FIG. 8B are configured by editing a plurality of banks by combining or separating them as shown in FIGS. 9 and 10, for example. Is.

That is, FIG. 9 and FIG. 10 are shown in the above-mentioned patent document 1 (Japanese Utility Model Publication No. 7-37385). Of these, FIG. 9 is a combination of bank 1 and bank 2 shown in FIG. In this example, only the channels to which some data is added among the reception channels (CH1, CH2,..., CH40) associated with each memory address are collected and a new bank ( Group) and group A (GRA). FIG. 10 shows a new group B (GRB) by selecting a wireless communication channel to which data is attached from CH 81 to CH 100 of the bank 5 alone. If comprised in this way, it will become possible to select only a desired one from many radio | wireless communication channels, and to perform scanning reception.
No. 7-37385

As mentioned above, the wireless communication device with the scanning reception function proposed by the same applicant has subdivided the entire wireless communication channel into a plurality of groups and can freely separate and combine them, greatly improving usability. It became possible to do.
However, in recent years, the number of usable communication channels has increased remarkably with the increase of the frequency of use and the advancement of digital technology, and therefore, an even more efficient scanning processing means is required.
That is, in the conventional wireless communication device scanning means, scanning is performed in the order of the set groups (banks), so that the bank of interest and the channel of interest receive scanning under the same conditions as other banks and channels. Therefore, if there is no incoming call on the target channel and it passes, the reception order will not come until after the end of one scanning cycle, and there is a high possibility that the signal detection timing of the target channel with few incoming calls will be lost. Met. Such a defect tends to become more prominent as one scanning period becomes longer.

In addition, the object to be scanned and received is often different depending on the situation at that time. Especially in amateur radio communications, etc., the ionospheric propagation situation changes depending on the time zone and season, such as HF band, VHF band, UHF band, etc. Therefore, if the target channel to be scanned can be freely edited according to the situation, a more effective operation is possible.
The present invention has been made in view of such conventional circumstances, and is provided with a scanning reception function capable of performing scanning reception by freely combining desired wireless communication channels depending on the situation. The purpose is to provide a communication device.

In the present invention, in order to achieve the above object, in the wireless communication device having the scanning reception function according to claim 1, a plurality of memory channels stored in association with respective memory addresses are divided into a plurality of banks. a memory bank processing means for optionally coupling or separating bank, a function for sequentially scanning receive memory channels belonging to the selected memory bank, in a wireless communication device having a single scanning-scanning the bank for scanning alone Bank attribute registration means for registering each of the bank and the combined scanning bank for scanning by combining with another bank, and one or both of the single scanning bank and the combined scanning bank during one scanning period Scanning with any number and order And scanning sequence setting means for setting the scanning sequence to the scan pattern having a region capable of setting input a desired bank advance plural kinds memory, and displays calling the scanning pattern, the Scanning pattern setting means for inputting and setting a desired bank in the bank setting input area of the scanning pattern, and means for sequentially receiving and receiving memory channels belonging to each bank in accordance with the set scanning sequence And
The invention according to claim 2 is characterized in that, in the wireless communication apparatus having the scanning reception function according to claim 1, the scanning sequence setting means further comprises means for arbitrarily setting the bank scanning order. To do.

According to a third aspect of the present invention, in the wireless communication device having the scanning reception function according to the first or second aspect, the memory channel corresponding to the memory channel belonging to each bank is checked to store the memory channel memory correction processing means collecting only, or memory sorting means permuting the frequency data stored in Memorichiyaneru in order of frequency, you characterized by comprising either or both.

Since the present invention is configured as described above, in the wireless communication apparatus having the scanning reception function according to claim 1, a plurality of memory channels stored in association with memory addresses are divided into a plurality of banks, and In a wireless communication device equipped with a memory bank processing means that executes separation freely and a function that sequentially scans and receives the memory channels of the selected memory bank, each is registered separately as a single scanning bank and a combined scanning bank It is possible to register a bank of interest that is desired to be scanned with priority over other banks by registering the bank attribute, and to register a single scanning bank and a combined scanning bank during one scanning period. One or both of these can be combined with any number of times and order Scanning sequence setting means for setting and registering so that the target bank is called multiple times during one scanning cycle, so that only the target bank is continuously scanned during one scanning cycle It is possible to call and receive more banks than other banks. In addition, the number of calls to the bank of interest can be set arbitrarily according to the circumstances of the situation, and other banks can be preferentially called, so even a wireless communication device with a large number of channels can quickly set the channel of interest. Scanning reception is possible.
Also, prepare multiple types of scanning patterns that have an area where you can set and input the desired bank, and call and display these as required, and input and set the desired bank in the bank setting input area of this scanning pattern. Thus, it is possible to quickly and easily construct a scanning sequence and immediately start scanning reception based on this, or store it in a memory.

In the wireless communication device having the scanning reception function according to claim 2, since the wireless communication device according to claim 1 is further provided with a scanning sequence setting means for arbitrarily registering the scanning order of the bank, the single scanning is performed. It becomes possible to preferentially monitor the bank as a channel of interest, and if there is an incoming call on these channels of interest, it can be preferentially received.
According to a third aspect of the present invention, in the wireless communication device having the scanning reception function according to the first or second aspect, a wireless communication device combining the useful means described in Patent Document 1 proposed by the same applicant is configured. Is possible. That is, in the case of having a memory collection processing means that checks memory data corresponding to the memory channels belonging to each bank and collects only the memory channels in which the data is stored, only the necessary channels are selectively edited and scanned. Can be added to reception. If various data are set as the data to be added, various usage methods can be considered. Furthermore, in the case of having a memory sort processing means for rearranging the frequency data stored in the memory channel in order of frequency, when the channel frequency is sequentially switched, the frequency is switched in the order of low frequency or high frequency. , Ru effect mower to increase the switching speed of the frequency.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. However, the technical terms, components, types, combinations, shapes, relative arrangements, and the like described in this embodiment are not intended to limit the scope of the present invention only to specific examples unless otherwise specified. Only.
FIG. 1 is a schematic block diagram of a wireless communication apparatus having a scanning reception function according to the present invention. The wireless communication apparatus shown in this example includes an operation key 1 for inputting various channel settings, bank settings, processing designations, and the like described below, an encoder 2 for setting memory channel addresses, and the like, and at least the present invention. A signal processing unit 3 that performs scanning reception processing according to the above, a display element 4 such as an LCD (liquid crystal display), a display drive circuit 5 that drives the display element 4, a radio reception circuit (RX) 6, and an antenna 7. Is. The signal processing unit 3 further supplies a CPU 31 for executing processing operations, an input port 32 for supplying signals from the operation keys 1 and the encoder 2 to the CPU 31, and a display signal from the CPU 31 to the display drive circuit 5. An output port 33, a ROM 34 for storing a program executed by the CPU and necessary data, and a RAM 35 for storing data necessary for calculation, newly generated data, and the like.

  With the above configuration, various functions described in detail below are executed. That is, a memory bank processing function that divides a plurality of memory channels into a plurality of banks and arbitrarily joins or separates the banks, a function that sequentially scans memory channels of a selected memory bank, and a bank is combined with a single scanning bank A function that registers each of the scanning banks separately, and a function that sets and stores a scanning sequence by arbitrarily combining the number and order of one or both of a single scanning bank and a combined scanning bank during one scanning period. A function that recalls and receives a stored scanning sequence, or a function that arbitrarily sets the bank scanning order, a memory collection processing function, a memory sort processing function, a scanning pattern setting function, and the above functions. Combination It realizes the allowed processing or the like.

  In this example, only the wireless reception circuit (RX) 6 is provided as a wireless communication device, but at the same time, a wireless transmission circuit (TX) is provided, and a transceiver function for controlling the transmission circuit and the reception circuit in association with each other is added. Also good. For example, the transive function stops scanning on the channel where the incoming signal is detected, operates the press switch of the added wireless transmission circuit while monitoring the reception channel, and sets the frequency corresponding to the wireless communication channel being received. It is a function that can be transmitted.

FIG. 2 is a channel scanning sequence diagram illustrating an example of scanning of the wireless communication device according to the present invention.
First, in the present invention, a bank attribute registration function (means) for registering each of a bank to be scanned separately into a single scanning bank for scanning alone and a combined scanning bank for scanning by combining with another bank, A function of scanning one or both of a single scanning bank and a combined scanning bank in any number of times and in any order during one scanning period is provided.

  In this example, it is assumed that a group (bank) GR0 displayed in a double frame is a single scanning bank (hereinafter referred to as “target bank”), and is called and received n times during one scanning period. , GRx, GR6, GR7, GR9,..., GRx (total n) are called one by one in order as a combined scanning bank (hereinafter referred to as “other bank”). It is intended to receive. In other words, in this example, each time n of the other banks GR2, GR6, GR7, GR9,. In this way, while the other bank is called once during one scanning cycle, the bank of interest is called n times, and the bank to be monitored is always set as the bank of interest. For example, monitor reception can be performed at more timing than other banks. The internal channel configuration of the banks GR0, GR2,..., GRx is described in detail in the method already described with reference to FIGS. 6 to 10 and Patent Document 1 (Japanese Utility Model Publication No. 7-37385). The method can be edited as appropriate using the above method. In addition, when grouping (banking), it is possible to divide banks into relatively small parts such as by region, by communication partner, by priority, by attention, etc., and to combine and separate desired banks according to the present invention. , More convenient operation becomes possible. The set channel scanning sequence is stored in a memory such as the RAM 35 in FIG. 1, and is configured so that it can be recalled and received as necessary.

  In the above description, an example of a scanning sequence in which each bank is arranged without distinguishing between a single scanning bank and a combined scanning bank has been shown. Banks GR2, GR6, GR7, GR9,..., GRx are configured as a combined scanning bank that is set in advance (with an identification code and a flag) when setting the bank. Good (bank attribute registration function). In that case, when storing as a scanning sequence, information specifying a single scanning bank (GR0), a combined scanning bank (GR2, GR6, GR7, GR9,..., GRx), and those Information for designating an array and information for designating the number of single scanning banks to be called in one scanning cycle are stored in memory, and each of these pieces of information is used as a parameter (setting variable) to store a scanning reception program in advance. Execute. Then, it is possible to easily and easily set a complicated scanning sequence in which a single scanning bank is continuously received for a designated number of times and then a combined scanning bank is called. For example, if the number of single scanning banks GR0 in FIG. 2 is set to 3, the first, second, third,..., N scanning scans of communication channels belonging to the respective banks of GR0 are 3 Scanning is performed continuously, and scanning reception is performed with a combined scanning bank interposed therebetween.

For such setting, a menu screen for designating a single scanning bank and a combined scanning bank may be displayed on the display screen, and guidance display may be performed so as to input the bank corresponding to the empty space. The number of continuous designations can be arbitrarily changed and set for a scanning sequence set and registered in advance.
It is also possible to set multiple independent scanning banks in the scanning sequence, individually set the number of consecutive single scanning banks in one scanning cycle, and set multiple combined scanning banks. Including them, a complicated scanning sequence can be set.

  FIG. 3 is a channel scanning sequence diagram showing another embodiment of the present invention. In this example, scanning reception is performed in the order of banks GR8, GR7, GR9, and GR1. That is, conventionally, the order of GR1, GR7, GR8, GR9 in the ascending order from the smaller group number to the larger one, or conversely GR9, GR8, GR7, in the descending direction of the smaller group number. Normally, scanning is performed in the order of GR1, but in this example, a function for arbitrarily setting in a desired order is provided regardless of the bank number. Then, the function of arbitrarily setting the bank (group) order is used in combination with the embodiment shown in FIG. 2, and the order of other banks is set to GR2, GR7, GR9, GR6,. It may be arranged as follows. Further, as known in a music playback apparatus such as a CD player, the bank arrangement order may be called at random.

  In this way, if the bank scanning order can also be set, if there is an incoming call on the channel in the bank to be scanned first, scanning will be stopped on that channel and reception monitoring will be performed first. Banks (channels) can be preferentially received. There are various scanning control modes. For example, when an incoming signal is detected, the function of continuing reception until the incoming signal ceases to remain on the channel, or after receiving for a certain period of time, the incoming signal continues. Even if it is a function to shift to the next channel, or a function to continuously receive incoming channel reception by the operator's operation in both of them, conversely, even if the incoming call is in progress, it is forcibly shifted to the next channel It is possible to set functions to be performed. Therefore, if these functions are used in combination and the channel of interest is set to be scanned first, efficient operation becomes possible. Note that the processing as described above can be executed by the signal processing unit 3 shown in FIG. 1, and processing programs and data for the processing are stored in the ROM 34 and the RAM 35 of the signal processing unit 3.

  FIG. 4 is a diagram showing another embodiment of the present invention. A plurality of types of scanning patterns are stored in memory, and these are recalled to quickly set a desired bank for each scanning pattern. Moreover, it is a diagram showing an example of a memory bank setting screen when a scanning sequence is easily constructed and scanning reception is immediately started based on this, or stored in a memory. FIG. 4A is a diagram showing an example of a scanning pattern display having an area in which a desired bank can be set and inputted. In this example, two banks are “notable bank 1” and “notable bank 2”. ”And one“ other bank ”as a combined scanning bank, and prompts the operator to enter the desired bank in each empty area, prompting execution, and if entered, Is stored in the memory, or scanning reception is executed in accordance with a scanning sequence based on the set scanning pattern.

  For example, as shown in FIG. 2, an example of a display screen in the case where the same bank is called n times and another bank is arranged between them and scanned is simply set and registered and stored. If such a display is performed by the display element 4 and a necessary bank number is input using the operation keys 1, it is possible to automatically arrange desired banks in a desired sequence. Instead of displaying the scanning pattern of FIG. 4 (a), a scanning pattern that has already been set and registered is called up and displayed, and the necessary part of the bank is changed and modified to another one, thereby creating a new one. A process of creating and storing a simple scanning sequence is also useful.

FIG. 4B shows an example of a display screen for setting the order of banks to be scanned. By inputting a desired bank number at the GR cursor position in each frame, the setting can be automatically registered. Is possible. This bank order setting is also used to set the order of the target bank (single scanning bank) 1 and 2 shown in FIG. 4A and the bank order in other banks (joint scanning bank). If configured to do so, it is possible to easily change the order of the banks as appropriate according to the situation at that time and execute scanning reception.
Similarly, FIG. 4C shows a display example when the memory construction is automatically performed when a group of friends is designated. If a display screen for memory setting is prepared as described above, a desired memory setting can be easily performed, and a memory can be appropriately called up as necessary.

  The present invention need not be limited to the examples described above, and various modifications are possible. For example, since a GPS system (Global Positioning System) device that has been miniaturized in recent years has been developed, such a position detecting means is mounted, and the position is determined based on the obtained position information of the local wireless communication device. It can also be configured to invoke a channel scanning sequence that includes an associated communication channel. At that time, region (position) information may be added to the channel scanning sequence to be stored. Further, for efficient operation, it is also possible to add time information as a parameter to the channel scanning sequence to be stored and automatically call a specific channel scanning sequence at a predetermined time. Would be useful.

  Further, if each means proposed in Patent Document 1 (Act No. 7-37385) is used in combination, a more efficient scanning function can be constructed. For example, the three functions of the memory bank function, the memory collection function, and the memory sort function described in the same document can be used as they are or after being modified. The memory bank function is a function that has already been described with reference to FIG. 7 and that divides a plurality of memory channels into a plurality of groups (banks) and combines or separates the banks. Although illustration of the separation of the memory banks is omitted, for example, it may be considered that the processing shown in FIG. 9 is performed in the reverse direction. That is, GRA in FIG. 9 is regarded as one bank, and some of them may be separated and separated into bank 1 and bank 2 at the top of the drawing.

  The memory collection function is a function for collecting only memory channels in which data is stored by checking the contents of the memory channels. As shown in FIG. 9, for example, when bank 1 and bank 2 are combined, CH1, CH3, CH5 , CH20, CH39, when data is stored and no data is stored in other CHs, the memory collection function is used to edit only the channels in which data is stored as memory channels. . FIG. 10 shows a case where the bank 5 is not connected to another bank, and data is stored in the CH 82, CH 83, and CH 100, but no data is stored in other channels. In this example, the channel in which data is stored by the memory correction function is re-registered in CH81, CH82, and CH83, which are new memory channel numbers. In this example, “channel number” is slightly different from the concept of “wireless communication channel” that is normally used, and is displayed as a memory channel that indicates an address as an arrangement order in each bank.

The memory sort function is a function for rearranging data indicating the actual frequencies stored in the memory channel in the order of frequency, and as shown in FIG. In the state where the frequency data is stored in the memory channel, the sort function is used to rearrange the memory channels for each frequency, and the memory channel in which no data is stored is the final channel CH20.
Since these processes are described with reference to the drawings in the same document, illustration and description are omitted here, but they can also be used in the present invention.

  FIG. 5 is a channel scanning sequence diagram showing a modified embodiment of the present invention. In this example, the first bank of interest is set to GR0, the second bank of attention is set to GR2, the other banks are set to GR7, GR9, and GR6. Priority bank. That is, as shown in FIG. 5, if GR0 → GR2 → GR0 → RG7 → RG0 → RG2 → RG0 → GR9 → GR0 → GR2 → GR0 → RG6 →... The priority bank GR0 is called six times, the next priority bank GR2 is called three times, and the other banks GR7, GR9, and GR6 are called once each. In this way, it is also useful for efficient scanning reception to configure a scanning sequence by setting priorities for a plurality of banks of interest for a plurality of banks of interest.

  Furthermore, various modifications are possible in the present invention. For example, a function of setting a bank of interest at that time may be provided based on past received data or the like. That is, in amateur radio and the like, since the ionospheric state changes depending on the time zone and season of the day, it is often experienced that the receivable radio communication channel frequency band fluctuates accordingly. These fluctuations are various, such as those with a short period and those with a relatively long period, but a certain degree of regularity has also been observed. Therefore, if you accumulate these past received data, select the channel of interest and the number of calls according to the situation at that time, edit them into the bank of interest, and receive scanning preferentially, Efficient reception is possible. In addition, various types of data are not limited to being stored on their own, but after various studies and editing, they are stored in portable recording media, supplied to the general market, and imported by the reading means provided in the wireless communication device. It is possible to construct an intelligent scanning sequence using data. Alternatively, if such information can be supplied in real time via an information distribution means such as the Internet, further interesting communication will be possible. At this time, learning information or information supplied from the outside is added as data of each memory channel described above, and can be used when selecting a bank of interest.

  Still further, if the above-described processing is grasped as a procedure and a program is created so as to realize them, the present invention can be achieved by simply installing these programs and necessary data by a computer function device installed in the wireless communication device. It can be implemented.
