The main computer 14 is connected to 3, and the wireless device 13 is connected to the interface 34. Amplifier 35
Is connected to a speaker 36 for sound generation.

On the other hand, since the mobile stations 2-1 to 2-n have the same configuration, only the mobile station 2-1 will be described. The mobile station 2-1 is provided with a communication control device 21 which receives GPS positional information and controls communication with the base station 1. That is, the car navigation device 22 and the wireless device 23 are connected to the communication control device 21. Further, the communication control device 21 has a taxi meter 24 provided with a switch for inputting the distinction between an actual vehicle and an empty vehicle, an information input device 25 for AVM,
An external input unit 26 for notifying an emergency or the like and a microphone 27 for voice input are connected. A GPS antenna 28 for communicating with GPS satellites is connected to the car navigation device 22, and an AVM (Auto Vehicle Monitor) antenna 29 for communicating with the base station 1 is connected to the wireless device 23. ing.

In the above configuration, the car navigation device 22 is connected to the mobile station 2-1 via the antenna 28.
(The same applies to the other 2-2 to 2-n), and the position data is converted into predetermined format data together with the vehicle number information, the actual vehicle and empty vehicle state information, and the like in the communication control device 21. It is transmitted from the wireless device 23 to the base station 1 via the AVM antenna 29.

In the base station 1, the wireless device 13 receives the data via the antenna equipment 15 and sends it to the operation control device 11. The operation control device 11 separates the data and transmits the vehicle number information and the position data to the interface 33.
Via the main computer 14. The main computer 14 displays, for example, a map of an area covered by the taxi office on the display device 16 in which an image of the vehicle based on the position data is overlapped. At this time, the image of the vehicle is additionally displayed with a distinction between an actual vehicle and an empty vehicle, a vehicle number, and the like.

In this state, the dispatcher designates a vehicle traveling in a desired area using the keyboard / mouse 17 and requests wireless communication. Then, a process as shown in FIG. 3 is performed by the operation control device 11. That is, for the vehicle specified above, for example, the vehicle number is received from the main computer 14,
The state of the vehicle is detected (S1).

Prior to the above detection, the operation control device 11
Causes the wireless device 13 to make a call based on the vehicle number, and performs the processing of the sequence shown in FIG. That is, the operation control device 11 transmits a signal of a call request (link request) (S11), and the mobile station having received the signal returns a call response (link response) signal (S12). The call response (link response) signal includes a vehicle number, status information indicating the distinction between an empty vehicle and an actual vehicle, and position data. The operation control device 11 having received the information includes a status indicating the distinction between the empty vehicle and the actual vehicle. The determination in step S1 is performed based on the information. Here, when it is detected that the vehicle is empty, the signal of the normal connection sound is output to the amplifier 35.
To generate a normal connection sound from the speaker 36 (S
2).

On the other hand, when it is detected that the vehicle is a real vehicle, a signal of the connection sound for the real vehicle is sent to the amplifier 35 to be generated from the speaker 36 (S3). The normal connection sound is, for example, a signal having a continuous pulse with a period t1 like the signal f1 in FIG. 5, and the actual vehicle connection sound is a logical product of the signal f2 having a pulse with a period t2 and the signal f1. This can be signal f3. The signal f3 is a signal obtained by repeatedly passing and not passing the signal f1 at a period of t2 / 2.

As a result, a connection sound corresponding to one of the above two types of signals is generated before reaching S13 during a call in the sequence of FIG. Can be determined by hearing.

Accordingly, during the call S in the sequence of FIG.
In 13, since the user is in a call after knowing that the vehicle is actually in use, the user is notified of an incorrect call without giving the details of the vehicle allocation, and proceeds to the vehicle allocation instruction work for the vehicle of the next candidate. Can be restored quickly.

FIG. 6 is a flowchart showing the operation of the second embodiment. In this embodiment, there are three types of connection sounds indicating the status of the mobile station, and in addition to an actual vehicle or an empty vehicle, a sound expressing a state such as an emergency or a break during a meal is generated. A state such as a break during a meal can be input, for example, by operating a key (not shown) provided on the taxi meter 24.

Therefore, the call response (link response) signal shown in FIG. 4 includes a vehicle number, status information indicating the status of an empty vehicle, an actual vehicle, and a rest, etc., and position data. 11 judges whether the vehicle is an actual vehicle based on the state information (S4). Here, when it is detected that the vehicle is a real vehicle, a signal of a normal connection sound is sent to the amplifier 35, and a connection sound for a real vehicle is generated from the speaker 36 (S
5).

On the other hand, if it is detected that the vehicle is not an actual vehicle, it is determined whether the vehicle is empty based on the state information (S6). Here, when it is detected that the vehicle is empty, a signal of a normal connection sound is sent to the amplifier 35, and the speaker 3
6 is generated (S7). Step S6
, When it is detected that the vehicle is not empty, it is in a state such as resting, and a signal of the other connection sound corresponding to this is sent to the amplifier 35 to be generated from the speaker 36 (S
8).

In this embodiment, other states besides the actual vehicle and the empty vehicle can be recognized at the time of wireless connection, and appropriate measures can be taken. It should be noted that four or more types of sounds may be generated to generate sounds that express the others in detail. Further, a short voice message may be used as the sound.
