Description

  The present invention relates to a positioning information providing apparatus and a control method thereof.

A GPS (Global Positioning System) is known as a positioning system using satellites. Further, IMES (Indoor MEssaging System) is known as a system that complements GPS on the ground. In IMES, it is difficult to capture positioning information from a GPS satellite (hereinafter abbreviated as “satellite”) (it is abbreviated as “transmitter”). .). The transmitter provides the positioning information of the transmitter to the GPS receiver (hereinafter abbreviated as “receiver”) instead of the positioning information of the satellite.
The positioning information transmitted by the transmitter includes coordinate information (latitude, longitude, altitude, floor number) of the position where the transmitter is arranged. The receiver uses the coordinate information of the transmitter that has captured the positioning information as its own coordinate information. For example, the transmitter is arranged on each floor of a building and provides positioning information such as the number of floors set in the transmitter to the receiver.

  As a conventional positioning information providing device, the transmission source of the received positioning signal is specified, and when the transmission source of the positioning signal is outdoors, the position is calculated based on the navigation message included in the positioning signal, and the positioning signal When the transmission source is indoors, there is one that obtains a coordinate value from message data obtained from a positioning signal (see, for example, Patent Document 1).

JP 2007-278756 A

In a moving apparatus having a space that is blocked by a door and moves at high speed, such as an elevator, it is easy to lose radio waves transmitted by transmitters arranged on each floor. Once the receiver has lost the radio wave transmitted by the transmitter, the receiver starts capturing the radio wave from the transmitter placed on the floor after moving by the moving means. A predetermined time (several seconds to several tens of seconds) is required from the start of acquisition by the receiver to the completion of positioning. Therefore, the user of the receiver cannot use services such as navigation using the positioning information from when the receiver loses the radio wave from the transmitter until the positioning is completed at the transmitter on the moved floor. .
On the other hand, when a moving device such as an elevator moves, the current position of the moving device changes with the movement. For this reason, even if a conventional transmitter in which coordinate information is fixed is installed inside the mobile device, correct coordinate information cannot be provided.

  An object of the present invention is to provide a positioning information providing apparatus and a control method therefor that facilitate use of positioning information when a receiver moves with a mobile device.

  In one embodiment of the present invention, the positioning information providing device includes a storage unit that stores, in a storage device, coordinate information of a position where the mobile device stops, and an acquisition unit that acquires information about a position where the mobile device is scheduled to stop And a reading unit that reads coordinate information corresponding to the position information acquired by the acquisition unit from the storage device, and a transmission unit that transmits positioning information including the coordinate information read by the reading unit.

  ADVANTAGE OF THE INVENTION According to this invention, the positioning information provision apparatus which smoothes the utilization of positioning information when a receiver moves with a moving apparatus, and its control method can be provided.

It is a functional block diagram which illustrates the hardware constitutions of a positioning information provision apparatus. It is a functional block diagram which illustrates the functional structure of a positioning information provision apparatus. (A) The figure which illustrates coordinate information memorize | stored in an IMES data storage part, (b) It is a figure which illustrates option information. It is a flowchart which illustrates operation | movement of a positioning information provision apparatus.

Hereinafter, the power supply apparatus according to the present embodiment will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected and demonstrated about the same location in each figure.
FIG. 1 is a diagram illustrating a configuration example of a system including a positioning information providing apparatus according to the present embodiment. In this embodiment, the case where a moving apparatus is an elevator (elevator) is illustrated.

In FIG. 1, a system including a positioning information providing device includes a positioning information providing device 1, a receiver 2, and an elevator control device 3. The car 4 is a structure that raises and lowers a user and has a door (not shown). The positioning information providing device 1 is arranged inside an elevator car 4. A destination button 31 is arranged on the car 4.
The positioning information providing device 1 and the elevator control device 3 are electrically connected to communicate with each other. The positioning information providing device 1 and the destination button 31 are electrically connected to a joint box 33a disposed on the car 4. The joint box 33 a and the fixed joint box 33 b are electrically connected by an elevator cable 34. The joint box 33b is electrically connected to the elevator control device 3 via the fixed cable 35.
A floor button 32 for calling an elevator is arranged on each floor and connected to the elevator control device 3. Further, FIG. 1 shows that a user having the receiver 2 can receive a radio wave output from the positioning information providing apparatus 1 on the car 4.

The elevator control device 3 moves the car 4 to the selected floor to be stopped next. The floor to be stopped is selected by, for example, pressing the destination button 31 pressed by the user or pressing the floor button 32. When there are a plurality of selected floors to be stopped, the elevator control device 3 sequentially moves the cars 4 to stop them.
The elevator control device 3 opens and closes the door of the car 4 according to an operation of a door opening / closing button pressed by a user or according to a predetermined condition. For example, the elevator control device 3 closes the door when a predetermined time elapses after the door is opened. The elevator control device 3 opens the door after moving the car 4 to stop at the floor scheduled to stop.
The elevator control device 3 can notify the positioning information providing device 1 of elevator operation information. The notification of the operation state of the elevator can be realized, for example, by using a specific wiring of the elevator cable 34 as a signal line.

  The elevator operation information includes information on the floor scheduled to be stopped next when the elevator car 4 stops. Floor information can be expressed arbitrarily. For example, numerical information such as “1”, “2”, and “3” is used. Also, the first floor (first floor, 1), the second floor (second floor, 2), the ground floor (GF), the first basement floor (first basement, first basement floor, B1), the middle second floor (mezzanine, M ) Or the like. The floor information acquired from the elevator control device 3 can be associated with the floor information included in IMES data described later.

  Further, the elevator operation information includes door opening / closing information of the car 4. The door opening / closing information includes, for example, four states: a state in which the door is completely opened, a state in which the door is completely closed, a door being opened, and a door being closed. Further, a state where the door is completely closed may be a closed state, and the other three states may be an open state. The door opening / closing information may be directly input to the positioning information providing apparatus 1 by a sensor provided on the door.

  The elevator operation information includes information on whether or not the car 4 is moving. The car 4 is moving when the destination button 31 is pressed and when the car 4 is moving (raising / lowering) and when the car 4 is actually moving. Since the destination button 31 is pressed while the car 4 is moving, it is estimated that the user is in the car 4.

  Further, the elevator operation information includes information on whether or not the elevator is in service. An elevator being in service means a state where a user can use the elevator. For example, when the destination button 31 is pressed during service, or when the floor button 32 is pressed, the elevator control device 3 moves the car 4 to a predetermined floor. On the other hand, “not in service” means a state in which the user cannot use the elevator, for example, due to maintenance.

Next, the hardware configuration of the positioning information providing apparatus 1 will be described with reference to FIG. FIG. 2 is a functional block diagram illustrating the hardware configuration of the positioning information providing apparatus 1.
In FIG. 2, a positioning information providing apparatus 1 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, an EEPROM (Electrically Erasable and Programmable Read Only Memory) 14, and a first communication. A control unit 15, a transmission antenna 151, and a second communication control unit 16 are provided.

The CPU 11 controls the operation of the positioning information providing device 1. For example, the CPU 11 reads a program stored in the ROM 12 into the RAM 13 and executes the RAM 13 as a work memory. The EEPROM 14 stores data used by the CPU 11 and processing results of the CPU 11. In the EEPROM 14, for example, IMES data for creating an IMES message described later can be stored.
The first communication control unit 15 performs transmission control of radio waves transmitted via the transmission antenna 151. The transmitted radio wave includes IMES positioning information. The radio wave transmitted via the transmission antenna 151 has the same radio wave characteristic (RF (Radio Frequency) characteristic) as the radio wave transmitted from the satellite, and the IMES positioning information includes a predetermined PRN (satellite in GPS). Number). Therefore, the receiver 2 that receives IMES positioning information can be used in common with a receiver that receives satellite positioning information. The first communication control unit 15 transmits positioning information at a predetermined data rate.
The second communication control unit 16 controls communication with the elevator control device 3. The 2nd communication control part 16 receives the information of the elevator which the elevator control part 3 transmits using the predetermined wiring of the elevator cable 34 demonstrated in FIG. The second communication control unit 16 may control communication by wiring using, for example, an optical cable or a coaxial cable.

Next, the functional configuration of the positioning information providing apparatus 1 will be described with reference to FIG. FIG. 3 is a functional block diagram illustrating the functional configuration of the positioning information providing apparatus 1.
3, the positioning information providing apparatus 1 includes a control unit 10 and the EEPROM 14 described with reference to FIG.
The control unit 10 includes functional units such as an elevator information acquisition unit 101, an IMES data reading unit 102, an IMES message creation unit 103, and an IMES message transmission unit 104. The EEPROM 14 includes an IMES data storage unit 141.

In the present embodiment, the control unit 10 is illustrated as being implemented by a program executed by the CPU 11. However, the method of realizing each function of the control unit 10 is not limited to this embodiment. For example, all or some of the functions of the control unit 10 may be realized by firmware implemented by an LSI such as an ASIC (Application Specific Integrated Circuit). Further, all or some of the functions of the control unit 10 may be realized by hardware.
Moreover, as long as each function of the control part 10 illustrated in FIG. 3 has the function demonstrated by each function block, for example, a plurality of function blocks may be combined into one function block. One functional block may be divided into a plurality of functional blocks.

  The elevator information acquisition unit 101 acquires the operation information of the elevator described in FIG. 1 from the elevator control device 3 via the second communication control unit. The elevator information acquisition unit 101 can acquire a driving command by receiving a predetermined command from the elevator control device 3. The elevator information acquisition unit 101 may store the acquired operation information in the EEPROM 14 or the like.

  The IMES data reading unit 102 reads, from the IMES data storage unit 141, coordinate information corresponding to the information on the floor scheduled to be stopped next when the car 4 acquired by the elevator information acquisition unit 101 stops. Here, details of the IMES data stored in the IMES data storage unit 141 will be described with reference to FIG. FIG. 4A is a diagram illustrating coordinate information stored in the IMES data storage unit 141. FIG. 4B is a diagram illustrating option information stored in the IMES data storage unit 141.

In FIG. 4A, IMES data has fields (items) indicating coordinate information of longitude, latitude, and floor number. For example, the top record illustrated in FIG. 4A indicates that the longitude is 35 degrees 40 minutes 35.2 seconds north, the latitude is 139 degrees 46 minutes 22.9 seconds east, and the rank is 1. Show. In the IMES data shown in FIG. 4A, records of coordinate information of all floors where the car 4 stops are recorded. In the present embodiment, the floor information acquired by the elevator information acquisition unit 101 has a one-to-one correspondence with the floor information stored in the IMES data storage unit 141. For example, if the floor information acquired by the elevator information acquisition unit 101 is “1”, the IMES data reading unit 102 reads the coordinate information of the above-mentioned record having the floor number 1 corresponding to the floor information of 1. However, the floor information and the floor information are not limited to one-to-one.
In addition, in this embodiment, since the elevator which moves perpendicularly was illustrated, the longitude and the latitude are the same on all floors. However, for example, in a moving device that moves horizontally or diagonally, the longitude and latitude are different.
In addition, the IMES data storage unit 141 may record, for example, coordinate information of the same longitude and latitude (with different floor numbers) inside the building.

In FIG. 4B, IMES data has a rank (field) and a field (item) indicating option information. The positioning information used in IMES can include a message type that can be freely defined by the installer of the positioning information providing apparatus 1. In this embodiment, option information is transmitted together with coordinate information. FIG. 4B illustrates a case where the building manager sets a security level for each floor. In FIG. 4B, the 12th floor is set as an open floor where entry is not restricted, the 13th floor is set as a security level a, the 14th floor is set as a security level b, and the 15th floor is set as a floor where entry is prohibited.
The manager of the building can arbitrarily determine an action in the receiver 2 in accordance with the received message type. For example, in the above security setting, when the user presses the destination button 31 on the 13th floor, an application corresponding to the security level a may be operated on the receiver 2. In addition, when the user presses the destination button 31 on the 15th floor, the receiver 2 may be notified that entry is prohibited.

  Returning again to FIG. 3, the IMES message creation unit 103 creates an IMES message based on the IMES data read by the IMES data reading unit 102. The IMES message has a predetermined number of words and bit arrangement determined for each message type. The IMES message creation unit 103 creates an IMES message using the coordinate information included in the IMES data according to the determined bit arrangement. When the IMES data reading unit 102 reads the option information described with reference to FIG. 4B, the IMES message creation unit 103 creates an IMES message according to the message type for transmitting the option information.

The IMES message transmission unit 104 transmits the IMES message created by the IMES message creation unit 103 as positioning information via the first communication control unit 15 described in FIG. The positioning information transmitted by the IMES message transmission unit 104 is received by the receiver 2.
The IMES message transmission unit 104 transmits positioning information according to a predetermined operation of the elevator based on the driving information acquired by the elevator information acquisition unit 101. The predetermined operation is a predetermined operation before the door is opened on the floor where the car 4 stops next. The IMES message transmission unit 104 can speed up the start of positioning by the receiver 2 by transmitting the positioning information of the floor scheduled to stop before the door opens on the next floor to stop. By speeding up the positioning start, it becomes possible to smoothly use the positioning information when the receiver 2 moves with the mobile device. In the present embodiment, as will be described later with reference to FIG. 5, a process illustrating an operation of closing a door as a predetermined operation will be described. However, the predetermined operation may be other than the operation of closing the door, and may be an operation that can accelerate the start of positioning by the receiver 2.

Next, operation | movement of the control part 10 of the positioning information provision apparatus 1 is demonstrated using FIG. FIG. 5 is a flowchart illustrating the operation of the positioning information providing apparatus. In the description of FIG. 5, FIG. 3 is referred to as appropriate.
In FIG. 5, the control unit 10 determines whether or not the elevator is in service based on the elevator operation information acquired by the elevator information acquisition unit 101 (S1). If not in service (S1-NO), the process is terminated. In this embodiment, it is assumed that the elevator information acquisition unit 101 constantly monitors the elevator control device 3 and acquires operation information.

  On the other hand, when the elevator is in service (S1-YES), the control unit 10 determines whether or not the door is closed based on the driving information acquired by the elevator information acquisition unit 101 (S2). ). When the door is closed (S2-YES), it is determined whether the elevator is moving based on the driving information acquired by the elevator information acquisition unit 101 (S3). When the elevator is moving (S3-YES), the control unit 10 acquires information on the floor scheduled to be stopped next when the elevator car 4 stops based on the operation information acquired by the elevator information acquisition unit 101. (S4). The floor to be stopped next is selected by the user in the car 4 pressing the destination button 31. The floor information acquired in step S4 is the coordinate information or option information described in FIG. When the information on the floor scheduled to be stopped next when the user presses the destination button while the car 4 is moving is changed, the information on the new stop floor is acquired (S4).

On the other hand, if the door is not closed, that is, if the door is open or is being opened and closed (S2-NO), information on the current stop floor is acquired. This is because the user may get off the car 4 at the current stop floor when the door is not closed. Therefore, even when there are a plurality of floors scheduled to be stopped, that is, when a plurality of floors are selected by the destination button 31, information on each floor can be transmitted to the user who gets off at each floor. It becomes possible.
Next, the control unit 10 creates an IMES message (S6), and starts transmission of positioning information based on the IMES message (S7). In the present embodiment, there is no possibility that the user in the car 4 gets off at the current stop floor, and the earliest timing before the door opens on the next floor where the car 4 stops. Transmission of positioning information starts when the door closes. Thereby, it becomes possible to advance the timing of the completion of positioning by the receiver 2 of the user who gets off at the next floor to stop. However, if there is a sufficiently long time until the car 4 moves to the next floor to be stopped, for example, the door is closed and the predetermined position is reached so that the positioning is completed at the timing when the car 4 stops at the next floor to be stopped. You may start transmission of positioning information after time passes. On the other hand, when the time until the car 4 moves to the next floor to stop is short, the operation before the door is closed (for example, when the destination button 31 is pressed or when the close button is pressed). You may start transmission of positioning information.
On the other hand, when it is determined in step S3 that the vehicle is not moving (S3-NO), the control unit 10 stops transmission of the IMES message (S8). When the user is not in the car 4, useless power consumption can be suppressed by stopping the transmission of positioning information.
This is the end of the description of FIG.

  In addition, in this embodiment, although the case where a moving apparatus was an elevator was illustrated, a moving apparatus is not limited to an elevator. For example, the present invention can be implemented in a vehicle, a ship, a cableway device, or the like in which a stop position is predetermined.

  As described above, the control unit 10 in the embodiment may be realized by a computer. In that case, a program for realizing this function may be recorded on a computer-readable recording medium, and the program recorded on this recording medium may be read into a computer system and executed. Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory inside a computer system serving as a server or a client in that case may be included and a program held for a certain period of time. Further, the program may be a program for realizing a part of the above-described functions, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system. You may implement | achieve using programmable logic devices, such as FPGA (Field Programmable Gate Array).

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes designs and the like that do not depart from the gist of the present invention.
