[0001]

[Industrial applications]

 The present invention relates to a wireless vehicle dispatching support system used to support the operation when an operator of a base station selectively instructs a plurality of mobile stations to dispatch a vehicle, such as a taxi wireless system.

[0002]

[Prior Art]

 In recent years, as one of the taxi radio systems, the mobile station returns a response signal to the dispatch call from the base station, and the base station displays the vehicle number of the mobile station that responded on the display. In addition, a system has been considered in which the operator instructs the mobile station to dispatch. For example, when a vehicle dispatch request arrives from the user to the vehicle dispatch center via a telephone line, the operator of the vehicle dispatch center makes a vehicle dispatch call from the base station to each mobile station, for example, by voice call. On the other hand, the driver of the mobile station pushes the response switch when he / she wants to dispatch the vehicle to the dispatch call. Then, a response signal including the vehicle number of the own station is generated by the mobile station and returned to the base station. When the base station receives the response signal, the vehicle number included in the response signal is displayed on the display. Based on the vehicle number of the mobile station displayed on this display, the operator instructs the responding mobile station to dispatch. With such a system, the mobile station driver can respond to a dispatch call from the base station by simply pressing the response switch, and there is no need to make a voice response with the microphone in each case. For this reason, the operability in response is improved, which can enhance driving safety.

[0003]

[Problems to be solved by the device]

 However, in this type of system, in general, when a plurality of mobile stations respond to a vehicle dispatching call from a base station, the vehicle numbers of these mobile stations are displayed on the display in the order of quick response at the base station. It is configured. For this reason, the operator of the vehicle dispatch center often issues a vehicle dispatch instruction to mobile stations that respond quickly, and as a result, the number of vehicle dispatches to each mobile station tends to be unfair. ..

The present invention has been made in view of the above circumstances, and an object thereof is to make it possible to average the vehicle allocation to each mobile station, thereby eliminating the unfairness of vehicle allocation among mobile stations. It is to provide a wireless vehicle dispatching support system capable of doing so.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the wireless vehicle dispatching support system of the present invention includes a response signal receiving means, a vehicle dispatching state detecting means, and a display control means in a base station. Then, the response signal receiving means receives each of the response signals returned from the plurality of mobile stations, and the past vehicle dispatch status for each mobile station corresponding to the received response signal is detected by the vehicle dispatch status detecting means. There is. Then, according to the detection result of the vehicle allocation situation, the display control means displays the display data representing the responding mobile station. Further, the present invention is characterized in that, when a plurality of mobile stations respond, the identification information of these mobile stations is rearranged and displayed in the ascending order of the number of vehicle allocations in the past.

[0006]

[Action]

 As a result, according to the present invention, in the base station, when responses are sent back from a plurality of mobile stations after making a vehicle dispatch call, the past vehicle dispatch status for each mobile station that responded is detected. For example, the vehicle numbers of the mobile stations are displayed in the ascending order of the number of dispatches according to the dispatch situation. For this reason, when an operator selects a mobile station, it is possible to preferentially select a mobile station with a small number of vehicle allocations in the past, which averages the number of vehicle allocations for each mobile station and The unfairness of dispatching to the station will be resolved.

【Example】

 The present invention will be described below based on embodiments.

FIG. 1 is a functional block diagram showing a configuration of a wireless dispatch support system according to an embodiment of the present invention. BS is a base station, and MS1 to MSn are a plurality of mobile stations, respectively. Shows.

Of these, each of the mobile stations MS1 to MSn is provided with a radio circuit 22 having an antenna 21, and the radio carrier signal transmitted from the base station BS is received by the antenna 21 and then demodulated by the radio circuit 22. To be done. Then, the demodulated audio signal is subjected to predetermined baseband processing such as amplification in the baseband circuit 23, and is then output from the speaker 24 in a loud voice. The mobile stations MS1 to MSn each include a response switch 25 and a response signal generation circuit 26. When the response switch 25 is pressed, the response signal generation circuit 26 generates a response signal including the identification number of its own station and supplies it to the wireless circuit 22. The radio circuit 22 modulates the carrier signal with the response signal and transmits the modulated carrier signal to the base station BS 1 by, for example, the press talk communication system.

On the other hand, the base station BS includes a radio circuit 12 having an antenna 11 and a control circuit (CONT) 13, and the control circuit 13 includes a microphone 14, a keyboard (KEY) 15, and a display (DISP) 16. A memory (MEM) 17 including a RAM and a RAM is connected to the bus. The radio circuit 12 performs a voice signal transmitting operation and a response signal receiving operation for calling a vehicle and instructing a vehicle between the mobile stations MS1 to MSn.

The control circuit 13 has, for example, a microcomputer as a main control unit, and has a transmission / reception control unit 31, a vehicle dispatch number counting unit 32, and a display control unit 33 as its control functions. The transmission / reception control means 31 connects the microphone 14 to the radio circuit 12 and puts the radio circuit 12 into the transmission state when a transmission request for a car dispatch call is input by the keyboard 15, whereby the base station BS is used for a car dispatch call. Set to a state where you can talk. Further, the transmission / reception control means 31 puts the radio circuit 12 into a reception operation state after the transmission operation of the vehicle allocation call is completed, and thereby makes it possible to receive a response signal from the mobile stations MS1 to MSn.

The display control unit 33 causes the display 16 to display the vehicle numbers of the responding mobile stations when the response signals are respectively returned from the plurality of mobile stations after the vehicle dispatching call is transmitted. This is for controlling.

When it is necessary to compare the number of vehicle allocations of the mobile station that responds during the display control by the display controller 33, the vehicle allocation number detection means 32 stores the past number of vehicle allocations for this mobile station from the memory 17. If the mobile station is read out for comparison, and the mobile station is instructed to dispatch the vehicle, the number of times the vehicle is dispatched to the mobile station is incremented, and the contents stored in the memory 17 are rewritten to the new number of vehicles. is there.

Next, the operation of the system configured as described above will be described. In the standby state, the operator of the base station BS monitors the occurrence of a vehicle allocation request using the telephone line. When a vehicle allocation request arrives in this state, the operator operates the keyboard 15 to input a vehicle allocation call transmission request. .. Then, in the base station BS, the control circuit 13 executes control for assisting vehicle allocation.

That is, as shown in FIG. 2, when the input operation of the dispatch request for vehicle dispatch is detected in step 2a, the control circuit 13 proceeds to step 2b and first performs the control for dispatch request. Run. Therefore, the microphone 14 is connected to the wireless circuit 12, and the wireless circuit 12 is set to the transmitting state. Therefore, in this state, when the operator transmits a call for calling a vehicle, the transmitted voice is collected by the microphone 14 and converted into a transmission signal by sound-electric conversion before being guided to the radio circuit 12. Then, in the radio circuit 12, a carrier signal is modulated by the transmission signal, and the modulated carrier signal is transmitted from the antenna 11 to the mobile stations MS1 to MSn.

On the other hand, in each of the mobile stations MS 1 to MSn, when a modulated carrier signal arrives from the base station BS, the modulated carrier signal is demodulated into a voice signal by the radio circuit 22 and the speaker is transmitted via the baseband circuit 23. A loud sound is output from 24. In other words, a voice message for calling a vehicle dispatch is output in a loud voice. In this state, when the driver of the mobile station presses the response switch 25 in order to respond to the dispatch call, the response signal generation circuit 26 generates a response signal including the identification number of the own station. It is transmitted from the circuit 22 to the base station BS.

On the other hand, in the base station BS, when the transmission of the transmitted voice for calling the vehicle allocation is completed and the operator performs a transmission end operation using the keyboard 15, the control circuit 13 brings the wireless circuit 12 into the reception state. The state is set (step 2c) in which the return of response signals from the mobile stations MS1 to MSn is monitored. When a response signal is returned from any mobile station in this state, the control circuit 13 determines in step 2d whether or not the response signal that has arrived is the first one, and if it is the first response. In step 2e, the display data relating to the responding mobile station is created and displayed on the display 16 here. For example, if a response signal arrives from the mobile station MS24, the past dispatch number "2" of the mobile station MS24 is read from the memory 17, and the past dispatch number "2" is included in the response signal. It is added to the identification number “024” and used as display data. Then, this display data is displayed on the display 16, and the process shifts to the monitoring of the vehicle dispatch completion operation in step 2i. FIG. 3 (a) shows an example of the display result.

Further, it is assumed that a response signal arrives from another mobile station MS39 in this state. Then, since this response signal is not the response that arrived first, the control circuit 13 shifts from step 2d to step 2f. Then, in step 2f, the number of past vehicle allocations of the mobile station MS39 is read from the memory 17, and in step 2g, this number of vehicle allocations is compared with the past number of vehicle allocations "2" of the mobile station MS24 which received the response signal first. To do. Now, suppose that the number of vehicle dispatches in the past by the mobile station MS39 was "1". Then, since the number of times of dispatch of the mobile station MS39 is smaller, the control circuit 13 shifts to step 2j. Then, in step 2j, the display position of the display data of the mobile station MS24 which is already displayed on the display 16 is shifted backward by one line, and the display data of the mobile station MS39 is displayed instead. FIG. 3B shows an example of the display result.

When the shift display is completed, the control circuit 13 determines in step 2k whether or not the display data of the other mobile station is displayed on the line preceding the display data of the mobile station that is currently displayed. .. Then, if nothing is displayed as in the case of FIG. 3B, that is, if the display data just displayed is displayed in the first line on the display 16, monitoring of the dispatch completion operation in step 2i is performed. Move to. On the other hand, when the display data of another mobile station is displayed on the previous line, the process returns to step 2f and the same control is repeated.

On the other hand, it is assumed that the display 16 displays the display data of a plurality of mobile stations as shown in FIG. 3B, for example, and a response signal further arrives from another mobile station MS5. Then, the control circuit 13 reads from the memory 17 the past number of vehicle allocations of the mobile station MS5 which has received the response signal at step 2f, and the read number of vehicle allocations at step 2g at the end of the display position on the display 16. It is compared with the past dispatch times of mobile station MS24 displayed in. If the past number of vehicle allocations of the mobile station MS5 is "5", the number of vehicle allocations of the mobile station MS5 is larger, so the control circuit 13 shifts from step 2g to step 2h. Then, in step 2h, the display data of the mobile station MS5 is displayed at the end of the display position on the display 16. FIG. 3 (c) shows an example of the display result. When the display control is finished, the control circuit 13 shifts to the monitoring of the vehicle dispatch completion operation in step 2i.

Similarly, every time a response signal arrives from another mobile station, the past number of vehicle dispatches of this mobile station is compared with the number of vehicle dispatches of the mobile station already displayed on the display 16, The display position of the display data of each mobile station on the display 16 is controlled according to the comparison result. Therefore, when response signals arrive from a plurality of mobile stations, the display data of these mobile stations will be displayed on the display 16 in the order of the smallest number of vehicle allocations in the past. Therefore, even if the operator mechanically selects the mobile station displayed in the top row of the display 16, the mobile station having the smallest number of vehicle allocations in the past is instructed to allocate the vehicle.

Then, when the vehicle allocation instruction is completed and the operator performs a vehicle allocation completion operation using the keyboard 15, the control circuit 13 shifts from step 2i to step 2l. Then, in step 2l, the number of vehicle dispatches of the mobile station that has issued the vehicle dispatch instruction, that is, the mobile station whose display data is displayed on the top row of the display 16 is incremented (+1), and the mobile station in the memory 17 Replace the old number of vehicle allocations in the above with the new number of vehicle allocations after the above increment. It should be noted that the display of the display data of each mobile station on the display 16 is erased after the rewriting of the number of dispatches is completed.

As described above, in the present embodiment, after the dispatching of the vehicle dispatching call, the base station BS receives the response signals returned from the mobile stations MS 1 to MSn, and the past dispatching to the mobile stations that responded is received. The number of times is read out from the memory 17 and compared, and the display data regarding the responding mobile station is sorted in the ascending order of the number of dispatches and displayed on the display 16 according to the comparison result. Therefore, regardless of the order of responses, the display data of mobile stations is always displayed on the display 16 in the order of the smallest number of dispatches in the past. Therefore, even if the operator mechanically selects the mobile station displayed in the first row of the display 16 as the vehicle allocation target, as a result, fair vehicle allocation can be performed.

The present invention is not limited to the above embodiment. For example, in the above embodiment, each time a response signal arrives, display control of display data relating to the mobile station is performed. However, a response acceptance period is set, the display order of display data for all corresponding mobile stations is determined according to each response signal that arrives within this period, and the results are displayed together. May be.

In the above embodiment, the display order is controlled based on the number of past vehicle allocations. However, the vehicle allocation frequency per unit time in the past is stored, and the display order is controlled based on this vehicle allocation frequency. It may be configured to do so.

In addition, regarding the configurations of the base station and each mobile station, the wireless communication method between the base station and each mobile station, the configurations and control procedures of the vehicle dispatch status detection means and the display control means, the contents of the display data, etc. The present invention can be variously modified and implemented without departing from the gist of the present invention.
