Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless communication device, and more particularly to a wireless telephone device having a function of storing incoming calls when the called party is absent.

[Conventional technology]

Conventionally, as a function for storing incoming calls when a called party is absent in a wireless telephone device, there is a method of continuously blinking an incoming call lamp, or a system in which an identification number of a calling side telephone device is sent to a called side as a telephone communication system. There is a method of storing the calling party identification number.

[Problems to be solved by the invention]

Such a conventional incoming call storage function when the called party is absent is merely a storage function. This storage function is convenient, but even if there is a desired incoming call when the called party is absent and no further incoming calls are desired, the wireless telephone device must be in standby state while the called party is absent, so it is useless. Power consumption. In particular, if it is suitable for the case where a battery having a finite capacity such as an in-vehicle type or a portable type wireless telephone device is used as a power source, there is a drawback that the finite capacity of the battery capacity is wasted.

An object of the present invention is to, for example, keep incoming information such as the number of incoming calls when the called party is absent and the identification number of the telephone device on the calling side within a preset desired range, and when the range is exceeded. An object of the present invention is to provide a wireless telephone device capable of preventing wasteful power consumption by turning off the main power source of the wireless telephone device.

[Means for solving problems]

A wireless communication device according to the present invention uses a first storage circuit that stores incoming call information when the called party is absent, a second storage circuit that stores presettable setting information, and comparison information from the comparison circuit. , A control circuit for controlling the main power supply,
Therefore, if the incoming call information including the number of incoming calls and the identification number of the calling communication device when the called party is absent is kept within the preset setting information range, if the range is exceeded, the wireless communication device Since the main power of can be turned off,
It is possible to prevent wasteful power consumption.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment according to the present invention.
As shown in FIG.
A storage circuit 2 for S1, a storage circuit 4 for setting information S2, and a comparison circuit 5 for comparing incoming information S1 of the storage circuit 2 and setting information S2 of the storage circuit 4 are connected. First memory circuit 2
In addition, the second storage circuit 4 is backed up even if the auxiliary telephone power source 3 is connected and the power supply to the wireless telephone device 10 which is a wireless communication device is cut off.

Further, the control unit 1 is connected to a terminal 9 to which incoming information S1 is input, and a main power source unit 6 controlled by the result of the comparison circuit 5, and the main power source unit 6 includes a terminal 7 for an external power source and an internal power source. It is connected between the terminal 8 for supply.

The operation of the wireless telephone device 10 of FIG. 1 will be described. The number of incoming calls for which the call was not established due to the absence of the called party or the identification number of the calling side telephone device for which the call was not established is used as the incoming call information S1 through the control unit 1 to the first storage circuit 2 Accumulated in. The storage circuit 2 is backed up even if the power supply to the wireless telephone device 10 is cut off by the auxiliary power supply 3, and the stored contents are not erased.

On the other hand, in the second storage circuit 4, the number of incoming calls expected by the user of the wireless telephone device 10 and the expected identification number of the other telephone device are stored as desired setting information S2. The storage circuit 4 is also backed up by the auxiliary power supply 3.

The comparison circuit 5 compares the setting information S2 with the incoming information S1.

Thus, when the user of the radiotelephone device 10 leaves the radiotelephone device 10 while expecting an incoming call, if the user wants to turn off the power of the radiotelephone device 10 if there are n incoming calls, the incoming call n times is preliminarily performed. It is set in the memory circuit 4. And during the absence, n
When the call has been received for n times and the call has not been established because the called party is absent for n times, the control unit 1 determines that the number of the incoming calls is n times preset by the comparison information S3 of the comparison circuit 5. When it is determined that they are the same, a control signal S4 for turning off the power is sent to the main power source section 6 so that the power from the external power source terminal 7 is not supplied to the inside of the wireless telephone device 10. That is, terminal 7
By cutting off between the internal power supply terminal 8 and the internal power supply terminal 8, useless power consumption can be prevented.

In other words, when the wireless communication device is a vehicle-mounted type or a portable type and uses a battery as a power source, even if the power is forgotten to be turned off, this function enables the battery capacity to be effectively used. In addition, even if the user forgets to turn off the power supply, even if the user is far away, the power of the wireless communication device can be turned off by calling n times.

Further, when the identification number of the other party's telephone device is sent at the time of incoming call, the identification number of the other party's telephone device expected by the called party is set in advance in the memory circuit 4, and the identification number and the called party are absent. The comparison circuit 5 compares the incoming call information S1 with the identification number of the calling side telephone device at the time. When these identification numbers match, the control unit 1 sends a power-off control signal S4 to the main power supply unit 6 to cut off the power supply of the wireless telephone device 10. That is, when the callee receives an incoming call from the place where he / she expects and the callee is absent, the power of the radiotelephone device 10 is turned off at that time, and power consumption can be prevented.

In other words, if the wireless communication device uses a battery as its power source, the battery capacity can be effectively used even if the power is forgotten to be turned off, and the power supply of the wireless communication device can be used even if it is far away if the power is forgotten to be turned off. Can be turned off.

In the above description, an example in which the power supply of the wireless telephone device is turned off by n number of incoming calls when the called party is absent or from the telephone apparatus of the specific identification number when the called party is absent has been described.
It goes without saying that information such as a combination of the number of incoming calls and an identification number, a plurality of identification numbers, etc. can be used as the power-off setting information. In other words, the method of turning off the power when there are either n incoming calls or calls from a specific identification number, or when both incoming calls are received, etc. You can choose freely.

Even when the power is turned off by a plurality of pieces of information in this way, since the incoming call information immediately before the power is turned off is stored, it is possible to determine which information caused the power to be turned off.

〔The invention's effect〕

As described above, according to the present invention, the incoming call information when the called party is absent is compared with the preset desired setting information, and when they match, the wireless communication device is powered off, thus wasting power. Without having to do so, there is an effect that the incoming call function when the called party is absent can be used. In addition, if a call is made using the same information as the preset setting information, the power of the wireless communication device can be intentionally turned off.
