FIG.

Description

  The present invention relates to a radio communication system, and more particularly to a radio communication system in an AVM (Automatic Vehicle Monitoring) system for taxi dispatch using a polling method.

  With the development of wireless communication technology, positioning technology using radio waves has greatly developed. Today, GPS (Global Positioning System) positioning systems using artificial satellites are used to position GPS receivers with an accuracy of around 10m around the world. Information can be obtained. This GPS positioning system is mainly used for car navigation, marine navigation, surveying, etc. In addition, with recent development of mobile communication systems, mobile data communication for a wide area can be easily performed. Such a GPS positioning system and a mobile communication system are fused, and a mobile location management system and a character transmission system are put into practical use. It is used for the purpose.

  FIG. 5 shows a block diagram of an AVM system for taxi dispatch using GPS. In FIG. 5, 501-1, 501-2,... 501-M are base stations. In addition, when representing a base station, it is referred to as a base station 501. Reference numeral 502 denotes a management center, which is connected to a plurality of base stations 501 by transmission lines 503. Reference numerals 504-1, 504-2,... 504-N denote mobile stations (taxi). In addition, when representing a mobile station, it is referred to as a mobile station 504. Reference numeral 505 denotes a communication area in which the base station 501-1 can communicate, that is, a so-called communication zone. The mobile station 504 located in the communication area 505 and the base station 501-1 can communicate with each other. Reference numeral 506 denotes a GPS satellite. Each mobile station 504 can receive position information 507 from the GPS satellite 506 and obtain position information (longitude and latitude) of the own vehicle. In response to an instruction from the management center 502, each base station 501 transmits a polling signal PO1 to each mobile station 504, and each mobile station responds to this polling signal PO1 with polling response signals SR1, SR2,. Send SRn to the base station. That is, in this system, the management center 502 collects vehicle dynamics information in the order of the vehicle numbers of the mobile stations 504 in the communication area 505 by specifying the mobile station vehicle number from each base station 501. The management center 502 can also be configured integrally with the base station 501.

  Next, a polling method of the AVM system for taxi dispatch shown in FIG. 5 will be described with reference to FIG. The polling method shown in FIG. 3 shows a case where the dynamic information of the mobile station 504 is efficiently collected in a radio communication system of a taxi dispatch AVM system composed of 300 mobile stations, for example. For example, if a digital SCPC (Single Channel Per Carrier) wireless device is used and the data transmission rate is 9,600 bps, for example, in FIG. When the polling is performed, the polling cycle T is 12.4 seconds including the pause period (0.4 seconds). Since there are 300 mobile stations, vehicle search can be performed once every 12.4 seconds. In this example, the method of polling 300 mobile stations with the polling signal PO1 is described, but it goes without saying that the mobile stations can be divided into several groups and polled for each group. Furthermore, it is needless to say that a two-channel system in which a polling signal from the base station and a polling response signal from the mobile station are transmitted on different channels has been put into practical use, and this system can also be used.

  The polling response signals from the mobile stations 504-1, 504-2,... 504-N (N = 300 in FIG. 3) for this polling signal PO1 are shown in FIG. ), Polling response signals SR1, SR2,... SR300 are transmitted from each mobile station to the base station 501 at a predetermined timing.

  Thus, in the above-described conventional AVM system for taxi dispatch, the mobile station itself detects and stores the current position of the mobile station using a GPS satellite. Then, based on the periodic polling signal from the base station, each mobile station transmits a dedicated transmission slot (polling response signal) assigned to each mobile station number of the dynamic position information of each mobile station with the base station. To return. In the base station, polling is sequentially performed for all the mobile stations, and the dynamic position information of all the mobile stations is grasped. In addition, at least one base station is connected to the management center, and the management center is closest to the mobile station, for example, the customer, which is most suitable for dispatch based on the dynamic position information of the mobile station according to the dispatch request from the customer. Search for mobile stations and dispatch taxi vehicles. The mobile station designated for dispatch moves to the customer and places the customer, but at this time, the customer tells the crew the designated place, and the crew usually drives the mobile station and heads to the destination. is there.

  In such a taxi dispatch AVM system, the customer informs the management center of his / her current position and requests a mobile station to dispatch. The management center searches for a mobile station by wireless operation, and performs an operation of dispatching the mobile station to the current position of the customer. In this case, for customers who have registered as members, there is the trouble of making inquiries to the dispatch management center by voice, using the customer's address, etc. wirelessly. There is a problem that it stops temporarily. In addition, although it is possible to respond to vehicle allocation with member information, if a registered member gets on the vehicle from a place other than the location registered by the member, confirmation of the destination is made to the member, or an inquiry is made to the vehicle allocation management center. There was a problem that it took time to do.

  In addition, in this type of conventional system, dispatch information, such as member information, is transmitted at the same time as dispatch, so the crew (taxi driver) chooses a member that is advantageous, so it is not unequal to the crew, There are also problems such as poor vehicle allocation efficiency. Therefore, there is a demand for a wireless communication system using an AVM system that does not require a crew member, and that is capable of equality and efficient dispatch.

JP 2003-217092 A

  As described above, in the conventional technology, since the member who registered the member number is inquired to the dispatch management center wirelessly by voice about the member's address and the like, the data transmission is temporarily stopped. Further, in the conventional system, since member information is transmitted at the same time as the vehicle is dispatched, the crew member selects an advantageous member, which is unequal to the crew member, and the vehicle dispatch efficiency is deteriorated. Accordingly, there is a demand for a wireless communication system using an AVM system that enables equal and efficient vehicle allocation.

  An object of the present invention is to provide a wireless communication system with high vehicle allocation efficiency.

  Another object of the present invention is to provide a wireless communication system capable of transmitting member information to a mobile station for registered members.

  Another object of the present invention is to provide a wireless communication system that transmits member information to a mobile station that has agreed to dispatch.

  Still another object of the present invention is to provide a wireless communication system that improves the operational efficiency of crew members.

  The present invention relates to a base station and a wireless communication system that collects information on each of a plurality of mobile stations in the base station by polling. The base station includes a central processing unit and a member registration database coupled to the central processing unit The central processing unit has a function of searching for member information in the member registration database based on a customer number transmitted from the mobile station and a function of transmitting the searched member information to the mobile station. Each mobile station has a display unit, and the central processing unit is configured to transmit the searched member information to the mobile station after confirming a customer number transmitted from the base station. .

  In the wireless communication system of the present invention, the mobile station further includes a car navigation device having a map database, and displays a destination route of the member on the display unit of the mobile station based on the member information and the map database. Configured to do.

  In addition, the present invention provides a base station and a wireless communication system that collects information of each mobile station by polling in the base station, wherein the base station is a central processing unit and a member coupled to the central processing unit The central processing unit has a registration database, and the central processing unit searches for member information in the member registration database based on a vehicle allocation request from a member, and the mobile station is located within a predetermined range based on a vehicle allocation request from the member A function of transmitting a vehicle allocation request to a predetermined number of mobile stations searched by the mobile station search, and a function of transmitting the member information to the mobile station, and receiving a vehicle allocation request from the base station. Of the mobile stations, the member information is transmitted to one of the mobile stations that has pressed the dispatching approval button.

  In the wireless communication system of the present invention, the member information is transmitted to the mobile station that has been pressed the earliest among the mobile stations that have pressed the OK button.

  Further, in the wireless communication system of the present invention, the central processing unit of the base station has a storage unit, the storage unit has a result data table of a crew member of the mobile station, and the result data table has at least the above-mentioned While registering the number of times the crew member of the mobile station presses the dispatch approval button, the result data table is appropriately updated.

  As described above, according to the present invention, member information is transmitted from the dispatch management center to customers who have registered as members, which is extremely convenient for crew members, and data transmission and the like are temporarily stopped. Therefore, a radio communication system with high vehicle allocation efficiency can be realized. In addition, since member information is transmitted to the crew member who has agreed to dispatch, there is no need for the crew member to select an advantageous member. In addition, there is a feature that can realize a wireless communication system that improves the operational efficiency of crew members.

  Embodiments according to the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of an embodiment of the present invention. The configuration of a radio communication system used in the present invention, for example, an AVM system for taxi dispatch, is the same as that of the system shown in FIG. In FIG. 1, first, the transmitting radio of the base station 501 will be described with reference to FIG. Reference numeral 101 denotes a central processing unit, 102 denotes a storage unit, 103 denotes a polling signal generation unit, 104 denotes a data transmission request signal generation unit, 105 denotes a radio, and 106 denotes an antenna. In addition, a present Example demonstrates the case where the base station 501-1 and the management center 502 are comprised integrally. The configuration of the mobile station 504 will be described with reference to FIG. In FIG. 1B, 107 is an antenna, 108 is a radio, 109 is a polling signal receiving unit, 110 is a data transmission request signal receiving unit, 111 is a slot setting unit, 112 is a storage unit, 113. Is a charge meter, 114 is a data generation unit, 115 is a car navigation device, 116 is an operation display unit, and 117 is a GPS antenna. The car navigation device 115 includes a position detection unit 118 that detects position information from the GPS antenna 117 and a map database 119.

  Next, this operation will be described. First, the transmission radio of the base station 501 executes an operation for obtaining various information from the mobile station 504, for example. Therefore, the storage unit 102 of the central processing unit 101 stores a mobile station number and generates a polling signal including information specifying the mobile station number to be transmitted in response to the first slot generated by the polling signal generation unit 103, and a data transmission request signal generation. The data transmission request signal to the mobile station generated by the unit 104 is transmitted from the wireless device 105 to each mobile station 504 via the antenna 106.

  The radio wave transmitted from the transmitting radio is received by the radio 108 via the antenna 107 on the mobile station 504 side. Among these, the polling signal is received by the polling signal receiving unit 109, and the vehicle number at the head of the slot is received. From the vehicle number of each mobile station.

  On the other hand, the data transmission request signal receiving unit 110 detects a data transmission request signal from the base station 501. Signals detected by the polling signal receiving unit 109 and the data transmission request receiving unit 110 are sent to the slot setting unit 111. The slot setting unit 111 sets the transmission slot timing of the data transmission slot of the local station. Further, the slot setting unit 111 continuously monitors the signal from the data transmission request signal receiving unit 110, and when the data transmission request signal is detected when the data transmission slot of the local station is reached, The generation unit 114 is activated to transmit data to be transmitted to the base station 501 via the radio 108 and the antenna 107.

  Note that the data generation unit 114 generates data by detecting, for example, an empty vehicle / actual vehicle based on a signal from the charge meter 113. The slot setting unit 111 is reset when the detection signal from the data transmission request signal receiving unit 110 is exhausted. The position detection unit 118 of the car navigation device 115 detects the position of the vehicle, for example, longitude and latitude, for example, using a GPS system. The map database 119 stores map data. For example, the map database 119 displays the current location of the host vehicle on the map from the position of the host vehicle detected by the position detector 118, that is, longitude and latitude information. In addition, the destination of the mobile station can be searched from the map database and displayed on the map as well. In addition, since the car navigation apparatus 115 is already well known, the detailed description about the structure and operation | movement is abbreviate | omitted. The operation display unit 116 has functions for performing operations of the mobile station, necessary data input, information display from the base station, car navigation display, and the like. The operation display unit 116 can also be configured integrally with the car navigation device 115.

  Next, the polling method used in the above-described embodiment of the present invention is the same as the polling method shown in FIG. 3, for example. That is, the polling method shown in FIG. 3 is a radio communication system such as an AVM system for taxi dispatch that includes a large number of, for example, several hundred mobile stations, such as a radio communication system that includes 300 mobile stations. FIG. 4 shows a case where the dynamic information of the mobile station 504 is efficiently collected. For example, if a digital SCPC (Single Channel Per Carrier) wireless device is used and the data transmission rate is 9,600 bps, for example, in FIG. When the polling is performed, the polling cycle T is 12.4 seconds including the pause period (0.4 seconds). Since there are 300 mobile stations, vehicle search can be performed once every 12.4 seconds. In this example, the method of polling 300 mobile stations with the polling signal PO1 is described. However, the mobile station is divided into several groups and polling is performed for each group. A two-channel system in which a polling signal and a polling response signal from a mobile station are transmitted through different channels has been put into practical use, and either method can be used.

  FIG. 4A shows the contents of the polling signal PO1. The polling signal PO1 is a signal from the base station 501 to the mobile station 504, and includes a signal type transmission area 401, a polling vehicle number designation transmission area 402, and an area 403 for transmitting transmission request, dispatch information, and customer information. The length (polling signal length) is 40 ms.

  Next, the polling response signal from each mobile station 504 in response to this polling signal PO1, as shown in FIG. 4 (B), polling response signals SR1, SR2,... SR300 (polling response signal from each mobile station). 40 ms) is transmitted to the base station 501 at a predetermined timing. This polling response signal SR is composed of a signal type transmission area 404, a car number information transmission area 405, a member ID, a boarding (alighting) time, a position, etc. (collectively referred to as dynamic information) and a data length 406. (Polling response signal length) is 40 ms.

  Next, the operation of the present invention will be described with reference to FIGS. According to the present invention, a wireless communication system is realized in which member information is registered in advance to notify a crew member of destination information based on a vehicle dispatch request from the member. That is, in this embodiment, the member information is notified to the crew after confirming the member number. This will be described in detail below. FIG. 2 is a block diagram showing an embodiment of a base station used in the present invention. In FIG. 2, 201 is a map database, 202 is a member registration database, 203 is a display unit, and 204 is an operation unit. In addition, the same code | symbol is attached | subjected to the same thing as FIG. In FIG. 2, the member registration database 202 is, for example, a customer registered as a member in a taxi dispatch AVM system, for example, a home position, a place where a member frequently visits (a store, a company, etc.) or a golf course position ( The location of the customer's location, etc.) is stored as a table. For example, Table 1 shows a database of customers registered as members as a table.

  In Table 1, A, B,... N are member numbers (or IDs), (X1, Y2),... (Xn, Yn) are the longitude and latitude information of the customer's home location, and the destination name is This is your home address. In addition, (M2, N2),... (Mn, Nn) are the longitude and latitude information of the customer's location, etc., and the destination name is the company name, department store name, etc., which can be displayed on the map database. (Latitude, longitude) is stored as information. In addition, the location of customers can be changed or added according to needs from the purpose of customer service at a taxi company or the like. Needless to say, such member information is managed so as to be permitted only in the wireless communication system used from the viewpoint of security.

  In this state, first, assuming that a member gets on the mobile station 504, for example, the mobile station 504-1, the crew member of the mobile station 504-1 hears the member number from the member and operates the mobile station 504-1. The display unit 116 is operated to transmit a member number search request to the base station 501-1 (step 601). The membership number can be converted into a card and read from the membership card with a card reader. The central processing unit 101 of the base station 501-1 (functioning as a management center) that has received the member number search request receives the member number, confirms the member number, and confirms the vehicle position of the mobile station 504-1. Then, a response signal is transmitted to the confirmed mobile station 504-1 (step 602). At this time, the central processing unit 101 can also display the member information and the position on the display unit 203 on the display unit 203, but at this time, the member information is not yet transmitted to the mobile station 504-1.

  Receiving the response signal from the base station 501-1, the mobile station 504-1 displays a member number search acceptance screen on the operation display unit 116 and returns it to the base station 501-1 (step 603). Receiving this reply, the base station 501-1 transmits member information (step 604). The mobile station 504-1 that has received the member information displays the member information on the member number search acceptance screen of the operation display unit 116 based on the member information sent from the base station 501-1 (step 605). With this configuration, each mobile station 504 can save time and effort to ask for member information from the member, and the member does not need to inform the crew member of his / her information, and the crew member can quickly know the destination. It is especially convenient for moving customers to unfamiliar places.

  As described above, since the mobile station 504-1 includes the map database 119 in the car navigation system, the mobile station 504-1 is based on the member information sent from the base station 501-1 and the map information from the map database 119. For example, the target location can be displayed as a map from the current location (step 606). FIG. 7 shows an example of the display screen of the operation display unit 116. In FIG. 7, P1 indicates the current location where the mobile station 504-1 has placed a member, and P2 is on the map based on member information (for example, latitude and longitude information) sent from the base station 501-1. , And R represents the optimum travel route R. As a result, the crew of the mobile station 504-1 can easily send the customer to the destination P2. The member information sent from the base station 501-1 is valid at the base station 501-1 while the member is on the mobile station 504-1. However, when the member gets off, for example, a taxi fee is paid. In the event that the member information is deleted, the security of the member information can be taken into consideration.

  In the above-described embodiment, the case where the mobile station 504 includes the car navigation device 115 including the map database 119 has been described. However, the mobile station 504 without the map database 119 may be used. In this case, map information is transmitted to the mobile station 504 from the map database 201 of the base station 501 to the mobile station 504, and a map display may be performed on the operation display unit 116 of the mobile station 504 based on this information. it can. In this way, it is not necessary to provide the map database 119 in the mobile station 504, and the mobile station 504 is characterized by low cost. Of course, in this case as well, it goes without saying that the position detection unit 118 is provided in the mobile station 504, receives the position information 507 from the GPS satellite 506, and detects the position of the own station.

  Next, another embodiment of the present invention will be described with reference to FIG. The embodiment shown here is an embodiment in which the member information is transmitted after the taxi driver understands the dispatch. In FIG. 8, first, when a vehicle allocation request is received from a member via a public line to the base station 501-1 (functioning as a management center), for example, the base station 501-1 displays the vehicle allocation position of the member. (For example, the current position) is confirmed, a taxi (mobile station) near the dispatch position is selected, and a dispatch request is made to the selected taxi (step 801). That is, as described in FIG. 3, the position of all taxis (mobile stations) is grasped by the base station 501-1 by the polling method, and includes the dispatched member's dispatch position, for example, within a radius of 5KM. Since the base station 501-1 grasps a plurality of mobile stations 504, for example, two mobile stations 504-1 and 504-2, the operator of the base station 501-1 has two mobile stations 504. -1, 504-2, a dispatch request is transmitted. Of course, these two mobile stations are known to be empty vehicles by collecting dynamic information by polling in advance.

  Of the two mobile stations 504-1 and 504-2 that have received the vehicle allocation request from the base station 501-1, the mobile station 504-1 receives the vehicle allocation request, operates the operation display unit 116, and presses the OK button. Press (step 802). The base station 501-1 receives a response signal from the mobile station 504-1 that has pressed the OK button, and the operator of the base station 501-1 determines the allocation to the mobile station 504-1, and determines the allocation position and member information. Transmit to the mobile station 504-1 (step 803). In this case, as the vehicle allocation position and member information, the member information shown in Table 1 is read from the member registration database 202 of the base station 501-1 and transmitted. The reason why the member information is transmitted to the mobile station 504-1 that has pressed the OK button in this way after the OK button is pressed is that if the member information is transmitted before the OK button is pressed, the taxi crew is advantageous or profitable. However, there is a problem that not only the vehicle allocation request from the member who does not profit is received but the vehicle allocation efficiency is not good and the inequality is caused. Therefore, there is a feature that it is possible to realize a vehicle allocation system in which the crew members themselves cannot select members by transmitting member information after pressing the OK button. In addition, by assigning a dispatch to the crew member who presses the OK button earliest, the working attitude of the crew member is also improved. This will be described later.

  The mobile station 504-1 that has received the member information acquires the vehicle allocation information, and searches for the member number in the operation display unit 116 based on the member information sent from the base station 501-1 in the same manner as in step 605 described in FIG. Member information is displayed on the reception screen (step 804). In step 805, information on actual vehicles and getting off by polling is transmitted to the base station 501-1 by a polling response signal.

  In step 806, information on the actual vehicle, getting off the vehicle, etc. is registered. In the present invention, the performance data of the crew can be created based on the above-mentioned data, and the performance of the crew can be improved. For example, a crew performance data table as shown in Table 2 is stored in the storage unit 102 of the base station 501-1.

  In Table 2, items such as the crew ID (or crew number), the number of times the OK button is pressed at the time of dispatch, the number of times the OK button is not pressed, or the priority of the next time described in the embodiment shown in FIG. 8 are provided. It is updated sequentially according to. For example, when looking at the crew member A, the number of times that the OK button is pressed indicates, for example, 10 times as the cumulative total of the day, and the number of times that the OK button is not pressed indicates, for example, 0 as the cumulative total of the day. Thus, crew member A knows that the work is very enthusiastic and aggressive. Therefore, for example, if there is a request for dispatch next time, the next priority such as prioritizing dispatch is marked. On the other hand, the crew member B indicates that the number of times that the approval button is pressed is, for example, 1 time as the cumulative total of the day, and the number of times that the approval button is not pressed is, for example, 12 times, as the cumulative total of the day. Therefore, it can be seen that the crew member B is not eager to work and is not active. Therefore, for example, even if there is a request for dispatch next time, priority is not given to dispatch, that is, the next priority is marked with x.

  In this way, the crew result data table is provided in the storage unit 102 of the base station 501-1, and is always updated with data obtained by polling. Therefore, if the manager periodically displays the result data table on the display unit 203, the work performance and work attitude of each crew member can be grasped, and a wireless communication system useful for crew member management can be constructed. Needless to say, each item in the result data table can be changed or modified as appropriate according to the way each crew member manages and the way of thinking.

  Although the present invention has been described in detail above, the present invention is not limited to the embodiments of the radio communication system described herein, and can be widely applied to radio communication systems other than those described above. Needless to say.
