Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is applicable to AVM systems (Aut, omat, ic
VehicleMonit, oring 5yst, a
The present invention relates to a method for displaying empty vehicles in an automatic display system for vehicle position, etc.

[Prior art] AVM systems use radio waves to determine the location and activity status (actual vehicle,
This is a system that automatically keeps track of whether vehicles are empty or in use at all times within the operations management center. In such an AVM system, in order to grasp the activity status of a mobile station, a radio wave called a polling signal is transmitted, and the mobile station that receives this radio wave sends a response signal back to the base station, and the base receives the response from the mobile station. By receiving the signal, the activity status and the station number (vehicle number) of the mobile station are displayed on a display device such as a CRT display.

[Problems to be Solved by the Invention] When displaying empty cars collected based on such polling, the vehicle may be a small car, a Toyota car, a sightseeing car, an excluded car, or a specific car (such as a team leader). Conventionally, when displaying the characteristics of such a car number so that it can be easily identified, it was conventional to simply use a specific mark (such as 口J, rOJ,
rΔ”). However, in cases where such characteristics overlap, for example, when a small car is an excluded vehicle, only one of them is displayed in the past, making it difficult to easily identify vehicles with multiple characteristics. there were. Therefore, it has been difficult to allocate such vehicles.

[Means for Solving the Problems] However, in the present invention, when the vehicle number in the vacant vehicle data collected by polling is a vehicle with a specific characteristic, the vehicle number is assigned a specific mark based on the characteristic. To provide a method for displaying an empty vehicle, in which a different specific mark is attached to the same location and displayed in a case where specific characteristics overlap.

[Example] Hereinafter, the empty car display method according to the present invention will be explained with reference to the drawings.

Now, if polling is performed by operating the keyboard 2 of the base station 1 shown in FIG. 1, the polling signal is transmitted to the mobile station (not shown) via the transmitter 3 and the transmitting antenna 4. On the other hand, a response signal from the mobile station is received by the receiver 6 via the receiving antenna 5. This received output is demodulated into a digital signal by demodulation means 7, and data detection means 8 detects whether or not there is a predetermined data component in this digital signal. When a predetermined data component is detected, the vehicle number data is stored in the main storage means 9 together with dynamic data such as empty vehicles, district data where the vehicle is located, and the like. Incidentally, the vehicle character storage means 10 stores character data of all vehicles in advance. As mentioned above, this character data includes a small car, a Toyota 1wt light car, an excluded car, a specific car, etc., and can be arbitrarily defined in addition to these. Therefore, the data collation means 11 checks whether the car number of the empty car in the main storage means 9 is a vehicle with a specific character based on the character data in the vehicle storage means 1o. The vehicle number will be displayed on the display device 12 with a specific mark.

Here, 1. For example, the mark attached to a small car is "◇",
The mark attached to Toyota vehicles is "*", and the mark attached to new personnel is "mouth". Since such marks are stored in the vehicle storage means 10 so that they can be duplicated for each vehicle, the car number of an empty car obtained by polling is such that the marks are superimposed on the same location as shown in FIG. will be displayed. Therefore, in this case, a total of four cars are empty, of which the car number "123" is a small car, the car number r256J is a small car and a Toyota car, and the car number is a new employee, and the car number is a small car and a Toyota car.

[Effects of the Invention] As mentioned above, in this invention, when displaying a mark obtained by polling that makes it possible to identify the specific characteristics of, for example, the car number of an empty car, the same mark can be displayed. If a vehicle has multiple characteristics at a location, the corresponding marks are displayed in a superimposed manner, so vehicle numbers with multiple characteristics can be easily identified, and therefore the allocation of such vehicles is easier. If there is a request, it is very easy to dispatch a vehicle.

Claims (1)

[Claims] Based on the polling signal, if the vehicle has a specific character, a specific mark is attached to the station number (car number) of the mobile station (vehicle) to display it. 1. A method for displaying an empty vehicle, characterized in that, if there are such marks, all the marks are displayed in a superimposed manner at the same mark display position.
