Abstract

PURPOSE: To effectively search for the staying place of a desired person by storing the order of areas to be searched for every individual and performing successively the due operations based on the stored order. CONSTITUTION: When a searching request is given from a terminal equipment 3-1 for a person carrying a transmitter 1-1, the frequency information on the signal transmitted from the transmitter 1-1 and the searching order information are read out of a storage part 4 through a network 6. These information are sent to a receiver controller 5 through the network 6. The controller 5 actuates a receiver 2-4 based on the searching order information and also sends the frequency information on the received signal. The receiver 2-4 sends the information showing whether the signal of the corresponding frequency is received or not. If the signal is received, the searching operation is finished and a fact that the person to be searched is staying on the 4th floor is reported to the equipment 3-1. If the signal is not received, the controller 5 actuates a receiver 2-3 and also sends the frequency information on the received signal to the receiver 2-3. The receiver 2-3 sends the information showing that the signal of the corresponding frequency is received or not to the controller 5. Thus the controller 5 repeats the preceding operations based on the searching order information and in resonse to the reception or non-reception of the corresponding signal.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an individual whereabouts search system in a premises, an office or the like.

[0002]

2. Description of the Related Art A prior art related to the present invention is disclosed in
50-34567, JP-A-52-116187, JP-A-60-143794
No. 3, JP-A-3-138594, JP-A-5-62089, JP-A-6-
As disclosed in each publication of the 53890 publication, to search for a single person, the entire premises, office, etc. were searched.

[0003]

However, the conventional system for searching the entire building for one person is very inefficient. For example, when a number of search requests are made at the same time, it takes a long time to search the last person in order to search for each person in turn, and there is a problem that responsiveness deteriorates.

An object of the present invention is to provide a system capable of efficiently searching for whereabouts.

[0005]

The whereabouts search system of the present invention has means for storing the order of areas to be searched different for each individual in the storage means, and causing the receiving means to operate sequentially based on the order.

[0006]

According to the present invention, the receiving means is sequentially operated in the order of search areas which are different for each individual and are stored in the storage means. For example, if the area is divided by floor,
If the storage device stores the fact that the search is performed in the order of the third floor, the first floor, and the second floor, the receiving means is operated in the order of the third floor, the first floor, and the second floor. However, if the presence of the person to be searched is confirmed on the way, the search is terminated at that point. Like above-mentioned,
The area to be searched can be limited and the whereabouts can be searched efficiently.

[0007]

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

FIG. 1 is a system diagram showing the configuration of an embodiment of the present invention. In the present embodiment, a portable transmitter 1 that transmits an identification signal having a different frequency for each individual, a receiver 2 that is installed on each floor and that can select the frequency of the signal to be received from the information transmitted from the receiver control device 2, A terminal device having an input device for inputting a search request, an output device for outputting a search result, and a read / write function for the storage device 3, a storage device 4 for storing the order of a search area different for each individual, and a storage device 4 installed on each floor The receiver control device 5 is capable of individually controlling the frequency selection of the receiver 2, and the network 6 connecting the devices.
In addition, the area shall be divided for each floor.

With this configuration, the operation will be described for the case where the storage device 4 stores information as shown in FIG. First, when a search request for a person having the transmitter 1-1 is issued from the terminal device 3-1, the frequency information and the search order information of the signal transmitted from the transmitter 1-1 are read from the storage device 4 through the network 6, and the network is read. The frequency information and the search order information are transmitted to the receiver control device 5 via 6. The receiver control device 5 operates the receiver 2-4 and sends the frequency information of the received signal to the receiver 2-4 according to the search order information. The receiver 2-4 informs the receiver control device 5 whether or not a frequency signal is received. If there is reception, the search is ended, and the fact that the searched person is on the fourth floor is notified to the terminal device 3-1 through the network 6. When there is no reception, the receiver control device operates the receiver 2-3 and sends the frequency information of the received signal to the receiver 2-3. The receiver 2-3 informs the receiver control device 5 whether or not a frequency signal is received. If there is reception, the search is terminated, and the fact that the searched person is on the third floor is notified to the terminal device 3-1 via the network 6. When there is no reception, the result of existence is transmitted to the terminal device 3-1 through the network 6. The operation flow is shown in FIG.

Next, the internal operation of the receiver control device 5 will be described. The receiver controller 5 includes a communication controller 5a,
It comprises a storage unit 5b, a central processing unit 5c, and an interface unit 5d with the receiver 2. The frequency information and the search order information are sent from the network 6 to the communication control unit 5a in the receiver control device 5.
And is stored in the storage unit 5b. The central processing unit 5c
The floor to be searched first is read from the storage unit 5b, and the state of the receiver installed on the floor to be searched is checked through the interface unit 5d with the receiver 2. If the search is being performed by another person, the process waits until the search is completed or moves to the search for the second floor to be searched. If it is not in operation, the receiver 2 is operated and the frequency information of the signal to be received is sent through the interface section 5d with the receiver 2. The central processing unit 5c reads the presence / absence of reception from the interface unit 5d with the receiver 2. If there is reception, the communication controller 5a informs the terminal device 3 of whereabouts. If there is no reception, the floor to be searched second is searched for as in the procedure. The process is repeated until the location of the person searching for the motion can be confirmed or all floors in the search order information are searched.

[0011]

According to the present invention, an individual's whereabouts can be searched efficiently.
