[0002]

2. Description of the Related Art Conventionally, as a home monitoring system, a system is generally used in which a contract is made with a specific security company, various sensors are attached to the house, and the security company is automatically notified when an abnormality occurs. Further, as a technique related to a security system using a wireless terminal, for example, Japanese Patent Laid-Open No. 2000-2000
According to the "portable security system" described in Japanese Patent Publication No. 36088, a technique is disclosed in which an abnormality detection sensor detects an abnormal state, and when an abnormality occurs, a surveillance camera notifies the portable information device of the situation. In addition, JP-A-10
According to the "door locking / unlocking method" described in Japanese Patent No. 292688-, there is a technology that enables locking / unlocking of a home lock using a wireless terminal and eliminates the need to worry about depositing a key with a third party such as a security company. It is disclosed.

[0003]

By the way, there are cases where the locked state of the house becomes a concern when going out. It would be good if it was near my house, but I couldn't even go home to check the lock at a remote place, and the fact is that I could end up doing my work without worry. Also, if you are worried about locking, you can contact a security company etc. and ask for confirmation of locking,
It would also be possible to construct a system for forcibly locking using a telephone.

However, I did not notice that it was not locked,
There are also cases where you go out as it is, in which case the above measures do not work effectively. In order to deal with such a case, it is most desirable to contact the person near his / her home and lock the person with his / her own key when he / she goes out in a state where the person is not locked.

Further, automatic locking is not a very desirable means considering that there is a possibility that there will be no means for opening the lock such as when the key is left at home. The conventional technique is effective when an abnormal situation such as the intrusion of a thief occurs, but it is not effective in the sense of preventive maintenance and cannot be forgotten to lock.

BEST MODE FOR CARRYING OUT THE INVENTION (Embodiment 1) A first embodiment according to the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a system configuration diagram of a wireless remote monitoring system. The present embodiment is a security system in a mobile wireless communication system having a function of contacting a wireless terminal which will be brought out near the home when the user goes out in an unlocked state. A home station (hereinafter simply referred to as “home station”) 3 for a wireless terminal installed in a house is a wired line control unit 3 a which is an interface between a fixed telephone 7 and a wired line 9 and an electronic lock monitoring unit which is an interface with an electronic lock 6. 3b, an overall control unit 3c that performs overall control of the home station 3, a wireless control unit 3d that performs wireless data transmission / reception, and a range in which the wireless terminal 4 manages the home station 3 (communication between the home station 3 and the wireless terminal 4) A location registration management unit 3e that stores whether or not

The wireless terminal 4 is specifically a standard of a second-generation cordless telephone system defined by the Association of Radio Industries and Businesses, RCR-STD-28 (revised 3.3 edition on March 2, 2000). A wireless terminal that has two operation modes: a public mode used in the mobile phone and a self-employed mode (operates as a child device or a wireless terminal in the home, and is automatically public when it is outside the home and out of the control of the home station). Wireless terminal that operates as a public wireless terminal of a wireless communication system). Further, the electronic lock 6 has a lock status notification function.

From the radio control section 3d, the radio terminal 4 is periodically
Send a message to know where you are. Wireless terminal 4
Returns a response when it receives a message, and notifies that its own terminal uses the wireless terminal home station 3. In this state, the wireless terminal 4 functions as a slave unit of the wireless terminal home station 3. When the wireless terminal 4 returns a response to the message from the home station 3, the location registration management unit 3e indicates that the wireless terminal 4 is under the control of the home station 3 (the home station 3 and the wireless terminal 4 are wireless. Information indicating that there is a positional relationship in which communication is possible is stored. Wireless terminal 4
When the person moves from home 8 to the outside and cannot receive the message from the wireless terminal home station 3, the wireless terminal 4 starts operating as a public wireless terminal 5. This presupposes that the wireless terminal has joined the public wireless communication system.

When the wireless terminal 4 does not receive a response to the periodically transmitted message, the overall control unit 3c of the wireless terminal home station 3 sends the wireless terminal 4 to the location registration management unit 3e. Information indicating that the station 3 is in an incommunicable position deviating from the communicable position is stored. When a plurality of wireless terminals 4 are present under one home station 3, each wireless terminal 4 is registered as to whether or not it is in a position where it can communicate with the home station 3. Then, for example, the location registration management unit 3e indicates that all the wireless terminals 4 are in positions where communication with the home station 3 is impossible, and thus it is determined that the person in the house has gone out. At this time, it is assumed that a person wears a wireless terminal and moves.

When it is determined that the wireless terminal 4 has moved outdoors and has gone out, the overall controller 3c monitors the electronic lock 6 via the electronic lock monitor 3b. The electronic lock 6 has a lock status notification function, and notifies the lock status of either lock or unlock in response to an inquiry from the electronic lock monitoring unit 3b. When the electronic lock 6 is not locked, the wired line control unit 3a uses the stored telephone number of the fixed telephone 7 to use the wired line 9 to access the public network 1 and the public base station 2 via the public network. A message indicating that the lock is not made is automatically transmitted to the public wireless terminal 5 by calling.

FIG. 2 is a flowchart of the control of the wireless terminal home station for monitoring the electronic lock and notifying the wireless terminal when the user goes out without locking the key in the wireless remote monitoring system.

The processing of the flowchart of FIG. 2 is performed by software, and operates periodically when the CPU timer times out or the like. First, the position registration status of the wireless terminal home station is determined (21), and if there is a wireless terminal whose position is registered, the electronic lock determination flag and the timer are initialized (22). When there is no wireless terminal whose position is registered, the electronic lock determination flag is determined (23), and if the determination flag is set, the process ends without performing any processing. This is the process when the wireless terminal has moved outdoors and the state determination of the electronic lock has been completed. If the electronic lock determination flag is cleared, the timer is determined (24), and if the timer has not expired, the timer value is subtracted (25) to end the process. Judgment (26). This has the meaning of preventing erroneous notification when the wireless terminal 4 is on the borderline of whether or not to register the location in the home station 3. Next, the state of the electronic lock is determined, a message is transmitted to the wireless terminal only in the unlocked state (27), and the electronic lock determination flag is set (28). By implementing the above flow chart, it is possible to check the electronic lock every time when the user goes out without being aware of it.

(Second Embodiment) A second embodiment according to the present invention will be described below with reference to FIG. FIG. 3 is a system configuration diagram of the wireless remote monitoring system. The difference from the first embodiment is that the fixed telephone and the wired line do not exist, and the telephone number management unit 13a exists in the functional block in the home station 13, and the home station 13 itself also has the function of a public wireless terminal. That is the point.

The telephone number management unit 13a stores a telephone number as a public wireless terminal of its own home station and a telephone number when the wireless terminal 14 becomes the public wireless terminal 15. Similar to the first embodiment, the home station 13 can communicate with the wireless terminal 14 only within the range of the home. Before the public wireless terminal 15 is notified of the unlocking of the electronic lock 6, the same processing as in the first embodiment is performed.

When informing of the unlocking of the electronic lock 6, the home station 13 uses the telephone number uniquely held by the telephone number management unit 13a, and makes a public call using the public base station 12 via the wireless control unit 13d. Then, a message indicating unlocking to the public wireless terminal 15 is automatically transmitted.

According to the above-described embodiments, it is possible to remotely monitor the state of the lock and notify the resident himself. For example, in the case where he / she is absent from home, he / she often forgets to lock the key. Helps prevent going out.

The monitoring of the lock state of the lock and the notification thereof have been described above as an example, but the object to be monitored is not limited to the lock and may be another device in which the owner of the wireless terminal should perform a predetermined operation.

[0019]

According to the present invention, the condition of the device is monitored and
The monitoring result can be notified to the operator of the device at a time when the device is not far away.
