Description

The present invention relates to a device for preventing loss of a monitored body and a position search device.

5 and 6 show an example of a conventional object position search device. Reference numeral 5-1 is that of Patent Document 1.
The communication means includes a communication means (tag reader) for communicating with the first IC tag provided on the fixed object and a second IC tag provided on the moving object, and the communication means uses the first IC tag as a new first IC tag. By reading, the position of the new fixed object is updated, and further, when the communication means is reading the second IC tag and cannot be read, the update information of the fixed object position at that time is read by the second IC. It is the position (actually in the vicinity) of the moving object of the tag. The good point is that the position of the fixed object is the position of the moving object without the need for a position measuring means such as GPS. The disadvantage is that it is not the actual position of the moving object.

Reference numeral 2 denotes a patent document 2, which is a Bluetooth (registered trademark) standard transmitter (beacon) worn on a mobile device, receives a signal from the transmitter, reads the ID of the transmitter, and provides self-location information. It is also equipped with a beacon communication device (such as a smartphone with an application installed, possessing location information) that transmits to the main control computer. Beacon has a wide search range of ~ 100 m, so it is suitable for searching for self-sustaining mobile objects that possess a beacon. The range is too wide to search for objects away from something, especially self-supporting immovable bodies. The feature of Patent Document 3 is to search for a migrant who owns a beacon, and this is assisted by a smartphone owner equipped with an application capable of detecting a beacon signal (dependence on others). There is a limitation on the reader side that is essential. In addition, since it is unknown until the self-sustaining mobile body enters the next detection range after it becomes undetectable, a large number of cooperators acting as leaders are required. There is no need to search at all times, and when you need to know something unknown, you are searching. However, there are unsatisfactory situations as a means to deal with the case where the beacon and the migrant are separated from each other and as a means for searching for an independent immovable body that can no longer be detected. This is because when searching for a self-supporting immovable body, the position immediately before signals such as tags and beacons cannot be detected is important.

Reference numeral 6-1 is that of Patent Document 3, and the on-board unit mounted on the vehicle for transporting the article has a radio signal receiving unit for receiving the signal of the active radio tag attached to the article and a position for acquiring the position of the vehicle. It is provided with an information acquisition unit, an ID number and position information from both parties, and a transmission control unit that transmits this related information and vehicle state information including the traveling speed of the vehicle to a server via a wireless signal transmission unit. Then, the server detects that the signal from the wireless tag is interrupted while driving, and recognizes that the wireless tag or the article is lost.
Since there is a position information acquisition unit, it is easy to relate to the position, and the tag reception signal and the position are related even before transmission. An on-board unit that loads a large number of articles on a vehicle and receives, acquires, and transmits the corresponding wireless tag signal is indispensable, and in many cases, a position information means such as GPS and a tag reader are not always provided, and before transmission. There are many situations in which it is not possible to associate and send. It is suitable for managing a large number of objects such as transporting a large number of goods, but it is not always suitable for handling a single object.
Reference numeral 6-2 is that of Patent Document 4, in which the portable transceiver receives the signal emitted by the tag attached to the object and relays it to the base station. When the object is separated and the portable transceiver cannot receive the signal, the base station sets the position of the object as the last position in front of the portable transceiver.
In this example, since the position is given by a portable transceiver, a position measuring device such as GPS is provided. The portable transceiver has a heavy burden of being configured to play the three roles of a tag reader, GPS, and a transmitter. The position can be searched via the portable transceiver, but the base station makes a judgment and the current judgment function is weak. It is troublesome to control whether the portable transceiver is always on or off, and it consumes power. Has a big drawback.

It is a figure which shows one Embodiment of the reader and the reader accommodating apparatus of the loss prevention and position search apparatus of the monitored body which concerns on this invention. An example of a conventional object position search device is shown. An example of a conventional object position search device is shown.

FIG. 1 is a diagram showing an embodiment of a configuration of a position search device for preventing loss of a monitored body according to the present invention. When the handler takes out the monitored object, it is often desired to prevent the loss on the way and to search for the lost position. The device of the book includes a tag 130 having an ID (identification code) such as an RFID or a beacon attached to the monitored body 120, and a reader 140 that communicates with the tag 130 and reads the tag information, and the handler 110 can read the tag information. By separately mounting the monitored body 120 having the tag 130 and the reader 140 on the body of the handler 110, it is possible to avoid losing the tag 130 and the reader 140 at the same time, and in the reader 140, the reader 140 attaches the tag 130. By setting the readable distance that can be read to be larger than the mounting interval between the tag 130 and the reader 140 on the monitored body 120, any one of the monitored body 120 and the reader 140 having the tag 130 can handle it. The reader 140 notifies the handler 110 when the person 110 is lost from the body. In that case, the reader 140 can also store the time at the time of notification and the ID of the tag 130. It is preferable that the monitored body 120 and the reader 140 having the tag 130 are housed in separate storage devices as shown in the figure, and are independently gripped by the body (with a strap or the like).

The above is the case of taking out by the handler 110 (take-out external environment), but it is usually used in a certain housing (for example, a car, a building, etc.) without taking out (operating housing environment). ).
Here, it is convenient to have the monitored body accommodator 150 and the reader accommodator 160 for accommodating the monitored body 120 having the tag 130 and the reader 140, respectively. Details of the reader accommodator 160 will be described later in FIG. Loss information and setting information via the input device 180 can be exchanged between the reader 140 and the external base station server 170 via the reader storage device 160.
Further, if there is a position information acquirer 190 that can acquire position information such as GPS and navigation in the housing, the combined information of time and position can be sent to the server 170. Further, it is convenient to have a collaborative device 191 (for example, a card reader for a card) in the housing.

FIG. 2 is a diagram showing an embodiment of a state in which the monitored body is prevented from being lost and the position search device is used according to the present invention. In the carry-out external environment of FIG. 1, in 2-1 the monitored body 120 and the reader 140 having the tag 130 are carried by the body of the handler 100 and are not in a lost state, so that the tag 130 and the reader 140 can be read. Inside, reading of the reader 140 is enabled. In 2-2, since only the monitored body 120 having the tag 130 deviates from the body and is out of the readable distance, the reader 140 cannot be read, and the reader 140 stores the time and the ID of the tag 130. The reader 140 outputs a notification to the handler 100. Similarly, in 2-3, since only the reader 140 is out of the body and out of the readable distance, the reader 140 cannot be read, the reader 140 stores the time and the ID of the tag 130, and the reader 140 , A notification is output to the handler 100. Naturally, a notification output (buzzer, etc.) is output 2 m behind the handler 100, for example. Since the probability that the monitored body 120 having the tag 130 and the reader 140 leave the body of the handler 100 at exactly the same timing is extremely low, the loss can be effectively detected.

FIG. 3 is a diagram showing an embodiment of the operation flow of the monitored body loss prevention and position search device according to the present invention.
The operation is mainly the operation of the reader. In 3-1 in the operating housing environment, the reader 140 is inserted into the reader storage 160. Information such as the time when the reader 140 is lost, the ID of the tag 130, and in some cases (beacon sharing, etc.), and the information on the usage conditions of the reader set via the input device 180 are transmitted via the reader storage device 160. Data is exchanged between the reader 140 and the base station server 170. After that, preferably, the power of the reader 140 is turned off, the operation is stopped, and the charging operation is performed.
In 3-2 in the take-out external environment, the reader 140 is pulled out from the reader storage 160, the power of the reader 140 is turned on and the operation becomes possible, and the tag reading operation is performed. If you can read tag 130,
Since the monitored body 120 is not in the lost state, the notification is stopped (stored data is erased) in the notification state, and the tag reading operation is repeated if the notification state is not in the notification state. If the tag 130 cannot be read, if the reading time is less than the desired set time, notification 1 (for example, a small sound is output) is performed, the tag reading operation is repeated, and if the reading time is longer than the desired set time, notification 2 is performed. (For example, a loud sound is output), the ID and time data of the tag 130 (or the reader 140) are stored, and the tag reading operation is repeated. On the way, when the unreadable (lost) item is collected and can be read again, the notification is stopped (in some cases, the stored data is deleted) and the tag reading operation is repeated.

FIG. 4 is a diagram showing an embodiment of a reader and a reader storage device of the monitored body loss prevention and position search device according to the present invention.
The reader 140 is stored in 4-2, the reader storage 160 is stored in 4-3, the reader 140 is stored in the reader storage 160 in 4-1. Is shown.
First, 4-2 is an example of the configuration of the reader 140. When reading the RFID tag, the reader 140 emits a radio wave to the RFID tag and reads the ID (identification code) of the RFID tag included in the radio wave signal returned from the RFID tag. In this case, the RFID tag includes a passive type that does not have a power source and rectifies the received radio wave and returns a signal as a power source, and an active type that has a power source and emits a radio wave by itself. The passive communication distance is about several tens of centimeters to several meters, and varies depending on the frequency of radio waves. The active type is about 1 m to 100 m. In the case of RFID tags, it is a responsive type that responds to the response of the reader 140, but when a beacon is used instead of the RFID tag, this is a spontaneous source of information, which the reader 140 reads. In the case of a beacon, the communication distance can be selected from several cm, 1 m, 10 m, and the like. The reader 140 includes a reader circuit 410 that functions as a reader, a timer 420A that keeps time, a notification device 430 that notifies when the tag 130 cannot be read, and a reader controller 440 that controls these. It has a substrate 400 and a power supply 450.
The power source 450 is a secondary battery circuit 451 particularly in this figure, so that when the reader 140 is held in the reader storage 160, it is charged as described in the flow diagram of FIG. The configuration is convenient because there is no need to worry about battery replacement. The charging terminal 452 of the secondary battery circuit 451 is exposed to the outside.
Further, in this example, the power supply from the secondary battery circuit 451 to the reader board 400 is mediated by a switch 453. The switch 453 is in the off state when the knob 454 is pressed, and in the connected state when the knob 454 is not pressed. (Left and right terminals are connected or separated by a black bar)

4-3 shows an example of the reader accommodator 160. It has a charging circuit 460 that applies a DC voltage for charging the secondary battery circuit 451 of the reader 140, a charging side terminal 461, and an input side terminal 462. If the timer 420B is provided, it is convenient because the reader 140 can store the data at the time when it leaves the reader storage 160. A transmitter / receiver for communication with the base station server 170 shown in FIG. 1 or a communication means 470 such as an Internet environment is provided, and these are controlled by a reader accommodator controller 480. The operation is shown in the flow chart of 3-1 in FIG.

4-1 is a state in which the reader 140 is stored by inserting the reader storage device 160.
The knob 454 is pushed by the protrusion 490 on the reader storage 160 side, and the switch 453 is in the off state. The charging side terminal 461 of the charging circuit 460 and the charging terminal 452 on the reader 140 side are connected. Further, the data terminal 401 of the reader board 400 and the controller data terminal 481 which is a terminal of the reader storage controller 480 are connected, and data can be exchanged between the reader board 400 and the reader storage controller 480. Power is supplied during the data exchange. The method is to have a means for storing the electric power required for data exchange after the switch 453 is turned off in the reader board 400, or to connect the data terminal 401 and the controller data terminal 481 from the reader storage controller 480. Power can be supplied through the department.

In 4-4, it is an example of setting the reading distance and the notification switching time by the reader 140, and the selection button at the time of setting is shown. In this example, 1m, 2m, 3m, 5 seconds, 10 seconds, 20 seconds, A 30 second select button is shown. When 2 m is selected, either the reader 140 or the monitored body 120 having the tag 130 is dropped, and when the distance is 2 m, the reader 140 outputs a notification output and the tag ID and time data. To store. Of course, even if the reader 140 is dropped, the distance is only about 2 m, so that the operator can detect the notification output.
The time setting is the time for switching between notification 1 and notification 2 in 3-2 of FIG. Of course, it may be one notification from the beginning.

When the reader 140 is stored in the reader storage device 160, the hook A141 of the reader 140 and the hook B161 of the reader storage device 160 are fitted and fixed.
It is also possible to use the monitored body 120 as an information card such as an IC card or a magnetic card and the collaborative device 191 of FIG. 1 as a card reader. In this case, the unique symbol of the monitored body 120 itself (attached tag) (Different from the ID of) is associated with the unique symbol of the collaborative device 191 and unrelated monitored objects can be rejected by the collaborative device 191.

As described above, the device for preventing loss of the monitored object and the position search device according to the present invention is set so that the tag and the reader are not lost at the same time, and when the tag and the reader are lost while being taken out, the operator is notified on the spot and the time is set. It is extremely convenient for industrial use because it can realize the advantages such as the position can be specified and the power supply can be easily managed.
