FIELD OF THE INVENTION The present invention relates to a cordless telephone control channel measuring device for measuring the frequency of use of a control channel when performing control over a wireless line between a base unit and a handset and notifying the measurement result. Regarding

[0002]

2. Description of the Related Art Conventionally, in a cordless telephone with a low power transmission, which is frequently used, the transmission frequency of a base unit is 380 MHz.
The z band is used, the transmission frequency of the handset is 250 MHz, and 12.5 k is used for each frequency band.
89 channels spaced at Hz are used. In such a cordless telephone, the connection between the master unit and the slave unit via the wireless line confirms the availability of the control channel, and sends the ID code and other control signals through this control channel.
After confirming that the ID codes match, switch to a free communication channel. The call is made on the switched call channel.

As described above, since the control channel is always used first, in order to avoid interference when a large number of cordless telephones use a small number of control channels, the control channel is transmitted for 1 second or less. Has been defined. Furthermore, in a cordless telephone with low power transmission, the control channel is two of 89 channels,
For example, 46 channels and 89 channels are set. When making a call through a wireless line using these two control channels, a cordless telephone that constantly searches the two control channels and uses a control channel that is infrequently used is used. Also, a cordless telephone that uses two control channels for making and receiving calls is also used.

[0004]

However, in the conventional cordless telephone set, it is usually assumed that the control channel is used infrequently. In practice, however, a plurality of cordless telephone sets are installed close to each other and used. May be frequent. For example, in the case of a cordless telephone used for business purposes such as in an office as compared to a household cordless telephone, the number of calls is large and the control channel is used frequently. Facsimile devices and OA devices such as personal computers are frequently used around this cordless telephone, and control is performed by unnecessary radiation (spurious) from a timing generator that generates clock signals of various frequencies in these devices. The channel (frequency) may be disturbed and control may not be possible via the wireless line between the master and slave.

The present invention solves such a conventional problem by measuring the frequency of use of a control channel when performing control through a wireless line between a master unit and a slave unit and notifying the measurement result. However, it is an object of the present invention to provide an excellent cordless telephone control channel measuring device capable of accurately avoiding a failure in which the control channel cannot be used due to an unnecessary wave or the like in the wireless line between the master unit and the slave unit.

[0006]

In order to achieve the above object, the cordless telephone control channel measuring apparatus of the present invention is a control for discriminating a control channel from a plurality of channels when making a call with a cordless cordless handset through a wireless line. Channel identification means, usage frequency measurement means for measuring the usage frequency of the identified control channel, measurement item in the control channel to be measured, measurement item content storage means for storing setting contents for this measurement item, and measurement item content storage The input means for inputting the setting content for the measurement item stored in the means and the measurement result of the frequency of use of the control channel based on the setting content for the measurement item stored in the measurement item content storage means are set for the registered measurement item. An alarm notification means for issuing an alarm when the content exceeds the content is provided.

With this configuration, the measurement item in the measurement control channel registered and stored in the measurement item content storage means and the setting content for this measurement item are at least the channel number of the control channel to be measured and the time that is the measurement cycle. The interval, the measurement time, and the determination rate indicating the rate of use of the control channel are used.

Further, the alarm notifying means is configured to notify by any one or combination of lighting by a light emitting element, display on the screen display showing the ratio of use of the control channel, sound generation, and synthetic voice.

[0009]

With such a configuration, the cordless telephone control channel measuring device of the present invention has the channel number of the used control channel which is the setting content for the measurement item in the control channel to be measured, the time interval which is the measurement cycle, the measurement time, and the determination. If the result of measuring the frequency of use of the control channel by the ratio exceeds the judgment ratio in the setting contents for the registered measurement item, lighting by the light emitting element, numerical value display of the judgment ratio on the screen display, sound, synthetic voice Either or a combination is used for notification. Therefore, the failure of the control channel being unusable due to an unnecessary wave or the like in the wireless line between the master unit and the slave unit is accurately identified. In this case, it is easy to separate the unusable obstacle of the control channel at the place of use, and the device can be easily and appropriately installed in a place avoiding the unusable obstacle of the control channel.
