Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a device that automatically collects and displays the dynamics of a large number of mobile stations (for example, wireless taxis) managed by a company on a CRT at a base station. The present invention relates to a vehicle dynamic display device in which a symbol indicating a direction from a specific point is displayed.

In the taxi business, it is necessary to know where and what dozens or more vehicles are currently doing over a long period of time from early morning until late at night. When a request for dispatch is received from a customer, it is desirable to quickly find an empty vehicle near the customer and quickly issue an appropriate dispatch order.

Conventionally, a vehicle dynamic display device for this type of taxi displays the vehicle numbers of all vehicles on a CRT, and the dynamic state is displayed by coloring the vehicle numbers. For example, an empty car is green, a paid car is red, a forwarded car is yellow, a closed station is on the back, an emergency is in a purple frame (punk color), and a premium is in purple.

However, with these dynamic displays, it is not possible to grasp the positional direction of the mobile station from a specific point (for example, the location of a base station, the center of a city, etc.).

The present invention was made to solve the above problems, and automatically (spontaneously) when a mobile station receives a polling signal from a base station or when the dynamics of the mobile station changes. , a vehicle dynamic display device that transmits dynamic data signals from mobile stations within a predetermined area to a base station, collects dynamic data of the mobile stations at the base station, and displays the collected dynamic data on a display means,

Next, the operation of the device according to the present invention will be explained.

At the mobile station (1), in order to inform the base station (2) of the current position, the driver presses the push button (3) of the position/direction data setting means (3).
a) Press any of (3h). Then, position/direction data indicating the direction of the current position is sent to the control CPU (81).Also, if the taxi meter (4) is operated,
Each time, dynamic signals such as vacant cars, rental runs, forwarding, etc. are sent to the control C.
It is sent to P U (8). Car number setting means (6) always outputs preset car number data. These data are sent to the base station (2) by polling from the base station (2), but in the event of an emergency such as an accident or robbery, the emergency signal generation circuit (7) can be operated to generate an emergency signal even without polling. A signal is sent to the base station (2).

Next, operate the keyboard of the base station (2) to control CPUCl! 1) The mobile station (1) emits a polling signal for data collection through the remote control unit, radio device α, and antenna αυ. This polling signal is transmitted to antenna 001 of mobile station (1). When received by radio (9),
From the mobile station (1), dynamic data is used for control cpUf8),
It is transferred to the base station (2) via the radio device (9) and antenna αQ.

The transferred signal is received by the antenna 01) and supplied to the remote controller α□□□ via the radio α. The remote controller (Lj separates the data signal and the audio signal and supplies the data signal to the signal processing device (one). The signal processing device (
At 19, the data signal is demodulated and supplied to the control CPUH, and the signal processed by the control CPUH is sent to the display means α0 via the display control circuit (2), and displays the dynamic state as shown in FIG. Specifically, Figure 2 shows a case where there are 50 taxis, and the numbers from 1 to 50 represent the car number of each taxi.This car number is the number of the mobile station (1). Displayed in different colors according to changes in dynamics.

For example, empty cars are displayed in green, paid cars in red, forwarded cars in yellow, closed stations in blue, emergencies in a purple frame (back color), and premiums in purple. At the same time, an arrow symbol indicating the direction of the current location is displayed next to the car number.

Therefore, empty cars in a certain area are colored by the car number (green).
Just use the arrow symbol @ to search for it.

Additionally, vehicle numbers in call status are displayed together in one place along with their dynamics. In this case, the car number that last entered the call status is displayed at the top. Vehicle numbers in emergency situations are also displayed in a separate location. Furthermore, the annual precept,
[3, Time etc. are also displayed.

Although the device shown in Figure 1 has a function in which the mobile station (1) responds when there is polling from the base station (2), even if there is no polling, the mobile station (1) responds spontaneously. It is also possible to transmit vehicle number, dynamic data, voice, position direction data, etc. to the base station (2) at the same time. Mutual communication is possible.

Next, Fig. 3 shows a case where dynamic data signals etc. are automatically (spontaneously) transmitted to the base station when the dynamic state of the mobile station changes, that is, a modified version of the device shown in Fig. 1 is used. This shows two examples. In this Figure 3, the mobile station (

In such a configuration, the mobile station (1) transmits the dynamic (
Whenever there is a change in the vehicle number (1) of the moving vehicle (1) in conjunction with the taxi meter,
Dynamic and positional data are transmitted to the base station (2) via a signal generator (8a), a radio (9) and an antenna. Similarly, when the mobile station (1) is powered on or when the arbitrary registration switch (e) is operated, the vehicle number, current movement, and position/direction data are transmitted.

Furthermore, the position/direction data setting means (3) and the audio microphone (
5) Every time you press, the press dynamics, car number signal and position direction data are transmitted. When an emergency situation (taxi robbery, etc.) occurs in the mobile station (11), when the emergency signal generation circuit (7) is operated, the emergency situation, car number signal, and position direction data are similarly transmitted.

Also, at the base station (2), the signal sent from the mobile station (1) is received by the radio device a via the antenna 0υ.
