JP4210393B2 - Mobile phone misplacement prevention device - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a preventing device misplaced mobile telephone and, more particularly, to a prevention device misplaced mobile phone to prevent misplacement of the mobile phone at the time of leaving out.
[0002]
[Prior art]
In recent years, mobile phones have become increasingly smaller and lighter so that they can be easily carried, and even if they are placed in bags, they do not feel their presence. Therefore, it is often misplaced.
[0003]
As a similar technique for preventing misplacement, there is a misplacement prevention device such as a bag. This uses weak radio waves, put the transmitter in a bag and wear the receiver. When the distance between the transmitter and the receiver increases, the received radio wave weakens, so this is detected and an alarm sounds with a buzzer.
[0004]
[Problems to be solved by the invention]
However, according to this, a transmitter and a receiver are necessary, and a receiver must be worn. That is, if the receiver is misplaced, it is not useful.
[0005]
In addition, since it is necessary to always turn on the transmitter to transmit weak radio waves when carrying, various inconveniences occur when applied to a mobile phone. For this reason, a device for preventing misplacement for mobile phones has not yet been put into practical use.
[0006]
By the way, in the home, since the mobile phone is usually placed in the charger holder, it is often left behind when going out. As described above, recent mobile phones have become increasingly smaller and lighter, and their physical presence has become thinner, making it difficult to determine whether they are carried by their weight, etc. When you feel you need to do it, you often realize that you forgot it. As a result, for example, an important business opportunity may be missed or a contact may not be made, which may lead to a credit problem.
[0007]
The present invention has been made to solve the above problems, and an object, as it is the configuration of a mobile phone, to be able to inform reliably misplaced mobile phone at the outer digital to the user An object of the present invention is to provide a device for preventing misplacement of a mobile phone.
[0008]
[Means for Solving the Problems]
To achieve the above object, the present invention includes a charger holder for a portable telephone for use in a building, a motion sensor for detecting a reception unit and a human body doorway disposed in the vicinity of the building, the charger Including a sensor for detecting the presence or absence of the mobile phone with respect to the holder, and operating a notification unit such as a buzzer based on information from the transmission unit that transmits the detection signal to the reception unit and information from the reception unit and the human sensor Control means, and when the human body is detected by the human sensor and the detection signal transmitted from the transmission unit to the reception unit is “telephone present”, the notification unit Is operated, and a warning meaning that the mobile phone is left behind is issued.
[0009]
According to this, a person passing through the doorway is detected by the human sensor. At that time, if the mobile phone is placed in the charger holder, the control means determines that the mobile phone is left behind and issues a warning by the notification means. This prevents misplacement of the mobile phone when going out.
[0010]
Transmission from the transmission unit to the reception unit may be wireless, wired (dedicated line), or AC power line, but it does not require a transmission antenna and reception antenna, and does not require any new wiring work. For example, an AC power line is preferably used. A pyroelectric sensor is suitable for the human sensor.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described with reference to the schematic diagram shown in FIG. The present invention provides a portable telephone in such households and offices, if when not in use many has been made on the assumption that it is placed in the charger holder.
[0012]
Therefore, in the actual施例this, a detector 40 and a transmitter 41 for detecting the presence or absence of the mobile phone TP in the charger holder 30. Detector 40 has a sensor 40a which is attached to the charger holder 30, "with the phone" to the transmitter 41 based on the output signals from the sensors 40a or sends a detection signal of "no phone".
[0013]
Incidentally, the sensor 40a is or microswitch switches, non-contact type, for example optical sensors, ultrasonic sensors, there may in a magnetic sensor.
[0014]
Moreover, the actual施例this (here, the entrance door) building doorway human sensor 42 disposed near the reception section 43 for receiving a transmission signal from the transmitter 41, the control unit 44 Contact and a buzzer 45 serving as notifying means driven by good beauty control section 44.
[0015]
The human sensor 42 detects a person passing through the entrance door, and various sensors used for opening / closing control of the automatic door, such as an ultrasonic sensor, a reflective infrared sensor, a pyroelectric sensor, a human weight. A tread pressure mat type sensor or the like for detecting the pressure is applicable, but among them, a pyroelectric sensor is preferable from the viewpoint of workability and maintenance during installation.
[0016]
The method of connecting the transmission unit 41 and the reception unit 43 can be a wireless communication method including a wireless transmitter 41a and a wireless receiver 43a, a wired communication method using a dedicated line 41b, or via an AC power supply line via the respective AC power supply lines 41c and 43c. Any method may be used, but the AC power supply line method is preferable in terms of simplicity.
[0017]
Control unit 44 may be microcomputers. Further, the microcomputer naturally includes a control element called CPU (central processing unit) or MPU (micro processing unit).
[0018]
Next, the operation of the real施例of this. A detection signal indicating whether or not the mobile phone TP is in the charger holder 30 is sent from the detector 40 to the transmitter 41. Upon receiving this detection signal, the transmission unit 41 sends a signal “with telephone” or “without telephone” to the reception unit 43.
[0019]
When the control unit 44 monitors the human sensor 42 and the receiving unit 43 and detects that a person has passed through a signal from the human sensor 42, the control unit 44 checks the received content of the receiving unit 43. If the received content of the receiving unit 43 is “with telephone”, it is determined that the cellular phone TP is left behind and the buzzer 45 is sounded to call attention to the person passing through the entrance door. When the received content of the receiving unit 43 is “no telephone”, the buzzer 45 is not sounded assuming that the mobile phone TP is carried.
[0020]
Note that a person who reports that the mobile phone TP has been left in the room is a person who leaves the building. Therefore, if there is a need to distinguish between people leaving the building and people entering the building, for example, human sensors are installed on both the indoor side and the outdoor side, and one of them detects the person first. You just have to judge whether
[0021]
That is, when the person is detected on and the person not detected is turned off, if the indoor human sensor is turned on first, it is determined that the person will leave the building, and the receiving unit The received contents of 43 are checked and a misplacement prevention operation is performed. In contrast, if the outdoor sensor is turned on first, it is determined that the person has entered the building and the misplacement prevention operation is not performed.
[0022]
Although the present invention has been described with reference to specific embodiments, modifications, alterations, and equivalent techniques that would be easily conceived by those skilled in the art are also included in the present invention. For example, in the above embodiment, a buzzer is used as the notification means, but it can be easily replaced with sound, a display lamp, or the like. Even in the microcomputer, since which port is used varies depending on the model, it can be arbitrarily selected.
[0023]
【The invention's effect】
As described above, according to the present invention, when exiting from the buildings at the time of De Soto, for the mobile phone left behind in is checked, it is not necessary to inconvenience thoughts aware of the forgotten have on the go.
