Abstract

PROBLEM TO BE SOLVED: To solve problems in a conventional position monitor system that has caused mis-discrimination and a delay in a discrimination time because of bad precision when monitored only with cell information and position calculation information of mobile communication in the case that a mobile communication terminal is mounted on a loitering aged person or the like, the position of the person is always monitored on the basis of the position information and deviation from the safe area around a specific point is monitored and that has had an increased error when the safe area such as vicinity of its own home is small. SOLUTION: When deviation from an area in the vicinity of the specific point of a mobile body is detected by inter-direct wireless communication between a reference terminal installed to a specific reference body and a mobile terminal carried by a mobile body, an alarm is immediately raised to a caretaker or a leader, the calculation of the longitude and the latitude of the location of the person to be protected is requested to a position information system using a PHS and the GPS, whether or not the result of calculation is kept within a normal activity registered in the system of this invention is discriminated, and when the discrimination indicates the deviation, an alarm is raised or the succeeding deviation processing system is connected.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flow monitoring system for objects utilizing wireless technology, and more particularly to a constant monitoring of moving objects such as wandering elderly people and valuables. Specifically, the mobile unit is determined by the wireless communication status between the reference terminal installed at the home of the wandering elderly person or the leader of the group trip (specific reference body) and the mobile terminal carried by the moving object such as the wandering elderly person or travel group member. If a deviation from the home area (area near a specific point) is detected, a warning is issued immediately to a parent or guardian, and / or PHS or GPS
Request the latitude and longitude of the position of the protected object from the location information system using the, determine whether the result is within the normal activity area registered in advance in the system of the present invention, if a deviation, to issue an alarm It was made.

[0002]

2. Description of the Related Art Japanese Patent Application Laid-Open No. 9-331 discloses a similar technique.
In step 571, the present inventor previously registers a large number of public CSIDs belonging to a normal activity area in the mobile terminal (PHS slave), and determines a specific ratio of a plurality of stations of the CSID having a good communication state at the location point by the aforementioned number. If it is not included in the registered CSID group, it is determined that it deviates from the normal activity area and the standby mode is changed from public to transceiver or public transceiver dual standby. In this technology, a computer system built in a mobile body requires a large number of non-volatile memory areas for registering a large number of public CSIDs belonging to a normal activity area, and a large number of comparison operations are required for deviation determination. Processing is heavy. In addition, there is a possibility that a determination error may occur.

[0003] The position (latitude / longitude) of the CS on the map
In principle, the information about the CSID is kept secret and is frequently changed. To register a large number of public CSIDs belonging to the normal operation area, bring the mobile terminal to be registered to the actual site and repeat the registration operation. You have to go around the area of activity, which is difficult.

In particular, even when receiving a CS having a good communication condition at a location point of a mobile unit, the receiving intensity is constantly fluctuated due to the influence of multipath even when receiving a good communication condition. In some cases, the deviation determination error is several hundred meters or more, so that it is a serious problem that a determination error or a temporal or geographical delay (departure determination delay) occurs in the statistical averaging process.

[0005] A location information system provider using a cellular mobile communication network (for example, PHS) without using the area departure detection in the vicinity of a specific point, negotiates an area with the requester in advance, and enters and exits the mobile. Monitoring system (NTT
A request for calculation of the location (latitude / longitude) of a location information system provider (NTT Docomo or Toshiba) or a location information system provider (NTT DoCoMo's P / Where service), and the result is within the normal range of activity using a personal computer or the like. It is also performed to determine whether or not.

[0006] However, in these cases, the calculation of the location of the mobile unit in the public mode must be repeated and executed at all times, resulting in enormous economic burden on communication costs and fees for use of the location information system, and the above-mentioned location. In information systems,
Regardless of whether the position calculation method is the reception electric field strength method or the reception time difference method, the error of position calculation ranges from several tens of meters to several hundreds of meters due to the influence of multipath, so the deviation determination delay including the statistical average time is included. May occur. It also increases communication traffic and puts pressure on normal calls.

Further, as an extension of the technology of using the RFID tag for physical distribution management, it is possible to detect a deviation from the area near a specific point and to issue an alarm, and there may already be an embodiment. There is nothing to determine whether or not it is within the range. Generally speaking, the reach of radio waves of RFID tags is 2-3 cm to 30
When used for dogs and cats (pets), the warning is too frequent when applied to the determination of deviation from the normal range. Absent.

Further, the specific point is limited to a building such as a house, and
Japanese Patent Application Laid-Open No. H11-027734 discloses a method of switching between a home mode (cordless mode) and a public mode of HS and comparing the reception strengths of the two to determine whether the building is inside or outside the building. It is disclosed to report. This is advantageous in that both modes are in the standby state, thereby preventing the occurrence of communication costs. However, it is complicated to determine whether the building is inside or outside by alternately switching between the two modes and comparing the two reception intensities, and a PHS control device is separately provided. Not only does this increase the size of the device and speed up battery consumption, and increase the price, but also the transmission power of the public base station is 200 mW,
There are also 500 mW and 2 W, which are as powerful as 20 to 200 times the transmission power of the cordless base unit, which is 10 mW. In addition, since the antenna gain of the public base station is larger than that of the public base station, there is a problem that the determination of the inside and outside of the building is often reversed with the reception electric field strength of both.

[0009] The range of freedom and safe behavior of wandering elderly people and the like is not limited to buildings, and it is necessary to allow outdoor activities such as gardens in houses and premises in facilities. This is a requirement for the mental stability and physical health of wanderers (family associations with the elderly in dread). For monitoring outdoors in a garden or the like, G
Although it is said that a PS positioning device will be installed,
In addition to the high price, there is a problem that the cost of location communication increases frequently. Another problem is that it is necessary to create and store an outdoor safety range as a database.

[0010] Further, there is a commercially available device that carries a dedicated transmitter of a weak radio wave other than the radio wave of public mobile communication or a specific low power and detects going out from the reception status by a receiver provided in a building or the like. With this type of device alone, it is impossible to connect to positioning, tracking, monitoring and supplementing after going out, and if you dare to connect, carry both a mobile terminal compatible with public mobile communication and the dedicated transmitter separately There is a problem that you have to do it.

[0011]

[Problems to be Solved by the Invention] The occupation of the non-volatile memory area for registering the normal active area is reduced and the processing of the computer is lightened. 2. Simple and easy registration of normal activity areas. The accuracy of the range of the 2 'normal operation area is improved, and the range is appropriately wide for practical use. 2. Include not only the 2 "building but also the outdoors in the normal operation area. 3. Reduce the judgment error and the judgment delay based on the cell identification error or the position calculation error in the departure judgment of the normal operation area. 4. Communication cost and location information system 4. Reduce the financial burden of usage fees, etc. 5. Eliminate the frequent occurrence of departure warnings and the sense of suppression of human rights due to confinement in narrow places such as indoors.

Hereinafter, embodiments of the means 1 to 67 will be described. As shown in FIG. 1, the present invention provides a fixed specific reference body (such as a nursing home, a group home, a hospital, a business establishment, or a general home) or a moving specific reference body (e.g., a vehicle such as a bus or a group travel guide). If the mobile device that is located near the specific reference point and the mobile terminal that is active near the specific reference object (area near the specific point) detects a deviation from the area near the specific point, Immediately notify the specific reference body (administrator / guardian / leader, etc.) and / or the monitoring center, and use the PHS or GPS (in this case, the mobile body combines GPS) with a specific point in the location information system. A request is made to calculate the latitude and longitude of the location of the mobile terminal that has deviated from the neighboring area, and it is determined whether or not the result is within a normal activity area registered in advance in the monitoring system of the present invention, and notified to a specific reference body and / or In which was to issue a warning.

Aspect 1 (means 1): Communication by programmed direct communication specifying a destination identification code (a code for identifying a mobile terminal such as a PSID) from a reference terminal. 1. There is no response from the mobile terminal having the PSID or the like even after waiting for a predetermined time. Response of the response from the mobile terminal having the PSID or the like received by the reference terminal is desirably averaged signal strength reduction of about 100 frames or / and deterioration of BER (bit error rate) or / and continuation of the deterioration for a predetermined time. . The averaged signal strength of the reference terminal reported from the mobile terminal having the PSID or the like is preferably reduced by about 100 frames and / or the BER (bit error rate) is deteriorated and / or the deterioration is continued for a predetermined time. If one or more situations are recognized, the reference body terminal itself determines that the mobile terminal having the PSID or the like with which communication has been attempted is out of or in the area near the specific point, or the monitoring center and / or the location information system. The terminal monitors itself and is notified from the terminal itself or the reference terminal and / or the mobile terminal, and determines that the mobile terminal is out of the area near the specific point or has deviated.

It is needless to say that, when all of the above three items are not recognized, it is determined that the vehicle is in the area near the specific point or has returned.

Mode 2 (Means 2): The specific reference body, the monitoring center, or the position information system which has been judged or notified by itself as being out of the area near the specific point or deviating in the mode 1 is audible / visual / mechanical vibration. A warning is issued by means of (1), and positioning and tracking of the position of the moving object are started. The position of the moving object and the monitoring system of the present invention, the ASP (Application Se
The danger area registered in the service provider or the position information system or the like is collated, and a higher-level alarm is issued, a higher-frequency position calculation or a supplementary dispatch is requested according to the degree of danger.

Aspect 3 (means 3): The reference terminal is a PHS self-service CS (commonly known as a home unit for home use), and the mobile terminal is a PH.
S is a PS (commonly known as a handset for home use), and the PS is set to a self-employed standby (commonly known as a home standby) or a public / private dual-waiting mode. The self-service CS is for example a PS number (P
Specify "SID" and send "Wireless status inquiry" message to each P
S sequentially waits for a "radio status report" from the PS. At this time, the radio status report from the PS cannot be received within a predetermined time, or the signal strength of the radio wave of the PS received by the CS is lower than a predetermined value or / and BER. (Bit error rate) is deteriorated, or the signal strength of the CS radio wave received by the PS returned in the “radio status report” is lower than a predetermined value or / and the BER (bit error rate) is deteriorated. When it is determined to be out of the vicinity area, the wireless channel disconnection message or the PS release message is immediately transmitted. However, PS
If a response (lower layer response or “radio status report”) cannot be received by the CS, a retry is performed at a predetermined interval (for example, 30 ms).

On the other hand, if the signal strength of the CS radio wave received by the PS returned in the “radio status report” is equal to or higher than a predetermined value and / or the BER (bit error rate) is good, it is determined that the area is in the area near the specific point and the battery is determined. In order to avoid exhaustion, a wireless channel disconnection message or a PS release message is sent immediately.

The above processing is sequentially repeated for one or more PSs belonging to the same specific reference body as the CS or one or more PSs registered for monitoring. The time required for one round is, for example, about 1 minute in consideration of the moving speed of the moving body and the PS battery consumption. When the number of PSs to be monitored is large and the time required for one round becomes too long, a plurality of CSs are used and the PSs are shared by the CSs.

Also, the PS is actually called by the extension and "synchronous"
The determination may be made based on whether a message (ringback sound) can be received, or the determination may be made only in a lower-layer link channel establishment phase, which saves battery power.

In particular, in a nursing home or a hospital where a plurality of self-service CSs exist, the location registration information (CS
ID, received electric field strength, etc.) are updated periodically (for example, every one minute), and when the received signal strength of the CS radio wave included in the location registration information at the PS falls below a predetermined value, the PS autonomously becomes predetermined. The received signal strength may be reported to the CS at intervals of (2).

In this case, the received signal strength reported from the PS becomes equal to or less than a predetermined value, or the signal strength, preferably the average of the radio waves received from the PS received by the CS, is equal to or less than a predetermined value, and / or the BER (bit error) (Rate) is deteriorated, or when communication with the PS is interrupted for a predetermined time or longer, it is determined that the area is outside the area in the vicinity of the specific point, and desirably immediately transmits a “wireless channel disconnection message” to the PS. Needless to say, it can also be applied to.

When it is determined that the area deviates from the area near the specific point, the operation is the same as that of the second means.

Mode 4 (Means 4): Both the reference terminal and the mobile terminal are PHS PSs (slaves), the reference terminal is in the transceiver mode, and the mobile terminal is in the transceiver mode or the public / transceiver standby mode. It has been set. The reference terminal knows a usable radio channel (carrier frequency and time slot number) by carrier sense, designates a transceiver number of the mobile terminal using a downlink slot of the radio channel, and transmits a "call message" to, for example, 2 It is transmitted for a second (maximum 10 seconds).

During this time, the mobile terminal does not return an uplink "synchronization message" when waiting in the uplink slot of the same radio channel, or the reception signal strength of the uplink "synchronization message" radio wave at the reference terminal is desirably averaged. If the value is equal to or less than a predetermined value or / and the BER (bit error rate) is degraded, it is determined that the area is outside the area near the specific point.

On the other hand, if the average received signal strength of the uplink "synchronous message" radio wave at the reference terminal is desirably equal to or more than a predetermined value and / or the BER (bit error rate) is good, it is determined that the area is within the area near the specific point. Desirably, in either case, a “wireless channel disconnection message” is sent to the mobile terminal immediately after the determination. This process is sequentially repeated for all the mobile terminals belonging to the specific reference body and / or the mobile terminals registered to be monitored.

When it is determined that the area deviates from the area near the specific point, the operation is the same as that of the second means.

Aspect 5 (means 5): In means 1, means 2, means 3 and means 4, when the mobile terminal departs from the area near the specific point, does the mobile terminal itself stop receiving a signal from the reference terminal for a predetermined time? Signal strength reduction and / or BER
When the (bit error rate) has deteriorated and / or when the reference terminal has determined that the reference terminal has deviated and has been able to receive the unidirectional transmission of the command message, the mobile terminal: 1. In the self-employed standby mode. 2. When in transceiver standby mode In either case of the private / public dual standby mode, control is performed by a program of the built-in computer system so that the public / transceiver dual standby mode or the public standby mode is set. Alternatively, any of these modes may be fixedly set in advance. This is to prepare for position information calculation in the public mode and subsequent position search in the transceiver mode.

[0052] Embodiment 6 (unit 6): reference object monitoring server: monitoring center information such as and / or pre normal activity region in the reference body terminal internal computer system (Computer BS M in FIG. ₂₎ based on the request from the family By data communication from or from a display device (DIS _{M in} FIG. 2)
A plurality of points surrounding the normal activity area of the map displayed in (1) are registered (eg, pointed (plotted) with a mouse). (The values recorded as the normal activity area are mainly numerical values of latitude and longitude. For example, a circle Center and radius, polygon and rectangle vertices, combinations thereof, etc.)

The reason that the normal activity area registration can be performed by the above method is that the location relationship between the CSID and the map is usually maintained by the operator of the location information calculation system through a special contract from the mobile communication operator. In addition, the answer to the position information calculation request is provided in the form of "latitude / longitude and / or X-ward / X-town / X-chome vicinity".

The computer system with a built-in reference terminal downloads the normal activity area information registered in advance by the above method, or the computer system with a built-in reference terminal has a display device capable of displaying a map and an input device such as a pen touch panel. it may be registered in the normal activity area information in a manner similar to that registered in the BS _M.

If the mobile terminal deviating from the area near the specific point is detected in the means 1, means 2, means 3 and means 4, a computer system with a built-in reference terminal (FIG. 2)
The user himself / herself connects to the server of the position information calculation system or the position information calculation service provider by his / her own program, specifies the deviated PS number, and requests the calculation of the location (latitude / longitude).

Alternatively, a computer (BSS in FIG. 2) of a server system (BSS _{M in} FIG. 2) attached to a specific reference body
Reported the PSID of mobile terminals that depart to _M), BS _M, which has received the report by specifying the PS number that deviates connected to the server or location information calculation service provider of location information calculation system by the program with its own Request calculation of the location (latitude and longitude).

When the position calculation result is returned from the server of the position information calculation system or the position information calculation service provider, a computer system with a built-in reference terminal or / and a server system (BSS _{M in} FIG. 2) attached to the specific reference body is used. computer (BS M in FIG. ₂₎ or displays the current position and the trajectory of the mobile terminal that deviates using the program and map data to be built respectively, the degree of risk compared to normal active area information pre-registered Calculate and issue warnings. In this case, in order to save the memory of the computer system with the built-in reference terminal, a part of the program and the map data may be downloaded from the monitoring center as needed.

Aspect 7 (means 7): Although omitted in FIGS. 1 and 2, when the specific reference body moves, the specific reference body to be moved is determined by using a position information calculation system using a GPS and / or a cell structure. Knowing the dynamic self-position. Needless to say, with a fixed specific reference body, the self-position can be easily known on the map. The specific reference body self-position obtained by these means and the mobile terminal obtained by the position information calculation system The current position of the mobile terminal relative to the self-position of the specific reference body is known from the current position of the mobile terminal and monitored.

In the example of the means 4, the communicable distance of the PHS transceiver is 200 to 300 m in radius along the road. This is the radius of the area near the specific point. For a wide area larger than this, a plurality of areas near a specific point may be arranged adjacently so as to cover the desired wide area and avoid overlapping as much as possible. Some duplication or lack is not a problem. The missing part in the required wide area only needs to be surrounded by a specific point area group.

The reference terminals in a plurality of specific point vicinity areas constituting the wide area may be connected to the monitoring center via a communication line, or may be connected to a monitoring server for managing the wide area by wire or wirelessly. It is a matter of course that another area monitoring system in the vicinity of a specific point may be provided in each of the areas separated from each other.

Next, the means 8 to 11 will be described. First, the main terms used in the description of the means 8 to 11 are defined. However, those defined in the means 1 to 7 are omitted. The autonomous identification radio wave transmitter (active RFID tag) is, for example, the product name of E-Code is Spider.

There is an ID tag or the like, and is hereinafter abbreviated as PT.

The transceiver for a passive RFID tag is, for example, Unified Monitoring of E-Code.
A passive RF system transmits a RF signal of 2 to 13.56 MHz while sequentially controlling one to several antennas in a system (hereinafter referred to as UMS) or the like.
When a reply from the ID tag is received (identification code = tag ID detection), the bar code reader has a function similar to a bar code reader that outputs the tag ID to the RS-232C port or LAN. Note that the maximum radio wave reach by combining UMS and PT is 3 m.

If the width of the antenna and the UMS (passive RFID transceiver, shown but not named) is narrower than the radio wave reach, only two antennas (ie, N = 1) are sufficient. In this case, the value of n is increased. In the illustrated example, n = 2.

Embodiments of the following means 8 to 11 will be described.

May be built in the PS because it is extremely small.

The radio wave reach distance between the AT (active RFID tag) and the RX (active RFID tag receiver) is up to 30 in the combination of E-Code products described in the definition of terms.
m, it is possible to cover a range of a radius of 30 m with one receiver. However, considering the safety, if they are arranged in a 40 m grid, the number of grids in the X direction = X and the number of grids in the Y direction are Y (20 + 40X + 20) An area of (20 + 40Y + 20) square meters can be regarded as a specific point vicinity area. Alternatively, they may be arranged in a line along the periphery of the area in the vicinity of the specific point, and the area may be limited to a band-like area formed by the area.

The reference body server (BS _M ) has a combination of a PS identification code (PSID) or / and a PS telephone number and a tag ID (RFID tag identification code) installed in each mobile body in advance and the reference body. server _(BS M)
Tag ID or / and PS phone number to be monitored by P
A database such as SID is constructed in advance.

As described in the definition of terms, each RX can be apparently received at the same time as transmissions from a plurality of ATs, and the received tag ID is updated and stored each time it is received in the memory. all aT i.e. mobile BS _M is existing in the area Taking sequentially read logical oR tag ID unit at predetermined intervals all RX is stored in the memory of the respective area (PSID or /
And PS phone number).

The reference server (BS _M ) stores information such as tag IDs to be monitored in its own database and / or PS telephone numbers and PSIDs and all existing ATs.
That is, it is needless to say that comparing a moving object (PSID and / or PS telephone number) can detect a moving object (PSID and / or PS telephone number) inside / outside or deviating / returning from an area near a specific point.

If the area near the specific point is relatively small, the tag ID and the PSID or / and the PS telephone number to be monitored by each RX are stored in each RX. It is needless to say that the mobile body that has moved in / out of the area near the specific point or has deviated / returned can be specified by comparison and collation.

The RX itself and / or the reference body monitoring server notifies the monitoring center and / or the location information system via the router of the location status of the moving body detected in the above description.

Mode 9 (Means 9): In mode 8, when the moving body departs from the area near the specific point, the reference body monitoring server itself or the notified monitoring center or the position information system sets the departed PS standby mode to the public / private mode. The mode is changed to the transceiver double wait mode, an alarm is issued to the reference body by means of audible, visible, mechanical vibration, or the like, and positioning and tracking of the position of the moving body are started using the function of the position information system. The position of the moving object and the monitoring center of the present invention, ASP (Applic
The danger area registered in the ATION Service Provider or the position information system is collated, and a higher-level alarm is issued or supplementary dispatched according to the degree of danger.

It goes without saying that the items described in the mode 6 (means 6) can be implemented except for the description of the computer system with a built-in reference terminal.

Aspect 10 (Means 10): AT _{M1 to} ATM _Mn attached to each of the moving bodies M _{N1 to} M _Nn in FIG.
(Active RFID tag) to PT _M1 to PT _Mn (passive RFID tag) and receiver RX for active RFID tag

ID tag transceiver). The public mobile communication terminal (for example, PS for PHS) and PT _M1 to PT _Mn (passive RFID tag) are illustrated separately in FIGS. 4 and 5, but the PT (passive RFID tag) is small and sheet-shaped. Therefore, it may be built in or attached to the PS.

The range of the radius of 3 m because the combination of the product of E-Code described in the definition of the term is 3 m at the maximum in the radio wave arrival distance between the PT (passive RFID tag) and the UMS (transceiver for passive RFID tag). Can be covered by a single receiver, but considering safety, a 2m square is defined as the radio wave reach range.

Similarly to the means 8, a plurality of antennas (U

An area of 4X + 2) (2 + 4Y + 2) square meters can be regarded as a specific point vicinity area, and thereafter, it differs from the means 8 except that the individual tag IDs detected and reported by the UMS are processed by the reference server or the monitoring center. Never. Alternatively, they may be arranged in a line along the periphery of the area in the vicinity of the specific point, and the area may be limited to a band-like area formed by the area.

Next, FIG. 5 will be described. FIG. 5 shows a case where the area near the specific point is a building surrounded by one building or one gate wall. G _{M1 to} G _Mn are composed of two or 2n antennas and a UMS (passive RFID transceiver) as described above in terms of terms, and the minimum number of antennas is the inner and outer two. If the width of the entrance / exit passage is smaller than the radio wave reach, only two (ie, N = 1) is sufficient, and if it is wide, the value of n is increased (in FIG. 5, all n = 2).
Has become.)

When the moving body (any of M _{M1 to} M _Mn ) moves from the inside to the outside after passing through the door, the UMS determines that the first inner antenna of the pair of antennas is the PT of the PT provided with the moving body. since detecting the tag ID to report the tag ID and an antenna located in the BS M _(reference body server) or the monitoring center, followed by the tag ID and the antenna position so the outer Antea detects the tag ID BS M _(standard Body server) or a monitoring center.

[0093] BS M _(reference body server) or the monitoring center can be determined that the mobile object has deviated from the specific point near the area of the order of antenna detects this the tag ID.
Similarly, if the outer antenna detects the tag ID first, and then the inner antenna detects the tag ID, it can be determined that the moving object provided with the PT having the tag ID has returned to the area near the specific point. Needless to say. UM
The above-described deviation / return determination may be performed by a program incorporated in S, and there is an advantage that LAN traffic can be reduced.

When the deviation is detected, it is notified to the monitoring center and / or the position information system, and if necessary, to the specific reference body by means of audible, visible, mechanical vibration or the like. It also requests the monitoring center to calculate position information, or changes the standby mode of the deviated PS to the public / transceiver standby mode.

It goes without saying that the items described in the mode 6 (means 6) can be implemented except for the description regarding the computer system with a built-in reference terminal.

Aspect 11 (means 11): In the aspect 10, when the moving body departs from the area near the specific point, the reference body monitoring server itself or the monitoring center or the position information system notified of the moving object sets the departed PS standby mode to the public / private mode. The mode is changed to the transceiver double wait mode, an alarm is issued to the reference body by means of audible, visible, mechanical vibration, or the like, and positioning and tracking of the position of the moving object are started using the function of the position information system.

It is a control sequence reference example showing the outline of the exchange of the command / response and information among the S network, the reference terminal (home unit), the mobile terminal, and the search device.

[0098]

As described above, in the present invention, the concept of the area near the specific point is used, and the departure judgment is performed not only by the mobile terminal and / or the reference terminal but also by the RS.
Since it is performed even when the SI value is lowered and the bit error rate is lowered, the accuracy of the normal activity range can be improved and the range can be set to a practically appropriate range. (Issue 2 ')

The specific point of the present invention and its departure determination are limited to a specific point in a building such as a home as in JP-A-11-027734, and the departure determination is not performed by comparing RSSI values at the time of switching between public and home. Since the above procedure is used, not only the building but also the outdoors can be included in the normal activity area (Problem 2 ")

The normal activity area registration can be performed by pointing (plotting) the area on the map displayed on the monitor screen by the monitoring center or / and the reference body server. If necessary, the area is downloaded to the mobile terminal. It becomes easy to register the area (Issue 2).

Further, since it is not necessary to register a large number of CSIDs belonging to the normal operation area in the mobile terminal, the non-volatile memory area of the mobile terminal can be saved. Is unnecessary, which means that the processing of the computer with a built-in mobile terminal is lightened (Problem 1).

Next, the departure of the area near the specific point is determined by the public PH.
Since it does not depend on the S network, there are no problems or determination delays due to cell identification errors or position calculation errors of the public PHS network (Problem 3).

When the moving object is in the area near the specific point, the monitoring is performed in the PHS private mode, the transceiver mode or the RHS mode.
Since the process is performed using the FID tag, no communication cost or location information system usage fee is required during this period (Problem 4).

The area near the specific point is not limited to the house, but may include a garden or a premises. Even if the area near the specific point is narrow, if the area deviates from this area, it is connected to the position calculation of the position information system. Since the danger level and the warning can be output, the frequent occurrence of the departure warning and the feeling of suppression of human rights due to confinement in a narrow place can be dispelled (Problem 5).
