JPH02271500A - Automatic communication managing system for running distance of automobile - Google Patents

Abstract

PURPOSE:To manage many automobiles in a real time by constituting this system so that the automobile measures a running distance from a start point and transmits it to the center every prescribed times, and the received running distance and the received time are stored in the center. CONSTITUTION:An automobile 11 sets a measured value of a running meter to an initial state at the time of start and starts its operation. An automatic transmitting equipment 15 stores in advance a telephone number of the center 16 and an identification number of the automobile 11, calls the center 16 every prescribed times and sends out automatically the identification number and a running distance. In the center 16, a processor 23 adjusts the received running distance and its received time every identification numbers and allows a storage device 24 to store them. Also, from the stored running distance and received time, the time when the automobile passes through the running distance on an operation schedule to the identification number is calculated, it is set as a real time and by deriving a difference to the schedule time, it is displayed on an indicator 26. In this state, in accordance with necessity, when the real time is delayed by a prescribed time or above against the schedule time, it is detected, and an alarm is raised.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a management system that confirms the current position of a vehicle traveling on a predetermined route Y and detects a deviation from a scheduled time.

"Prior Art" In this type of conventional management system, the driver manually reports the current location of the vehicle to a center via a wireless line. In this way, in the past, reporting was done manually, which made the operation complicated, and it was difficult to report at short intervals. Since the processing is done manually at the center, it is difficult to manage a large number of vehicles.

"Means for Solving the Problem" According to this invention, in a car, the distance traveled from the starting point is measured with an odometer, and the automatic calling device and car phone call the center at fixed distance or fixed time intervals. The driving distance is transmitted, and the center stores the received driving distance and the time at which it was received, and displays the current position of the car and the deviation from the scheduled time.

"Embodiment" FIG. 1 shows an embodiment of the present invention. A car 11 traveling along a predetermined route is equipped with a car phone 12 and a wireless fi 13.

The present invention is provided with a travel meter 14 that measures the travel distance of the automobile 11 from its starting point and outputs the measured value as a digital signal, and an automatic transmitter 15. The automatic calling device 15 stores the telephone number of the center 16 and the identification number of the vehicle 11, and also has a built-in timer.
The telephone number of the center 16 is transmitted every fixed period of time, for example, every 10 minutes, and when connected to the center 16, the identification number of the automobile 11 and the distance traveled by the mileage meter 14 at that time are transmitted to the center 16.

The signal transmitted from the car 11 is sent to the car phone base station 17
, the mobile telephone exchange 18 , the telephone office 19 , and the general subscriber telephone line 21 to be sent to the center 16 . That center 16
The signal sent to is supplied via the transmitting/receiving section 22 to a processing device 23 consisting of a personal computer. A storage device 24, a clock device 25, and a display 26 are connected to the processing device 23. The storage device 24 stores in advance a travel schedule consisting of the mileage and scheduled time for each vehicle. Each time the mileage is received, the center 16 organizes the mileage and the time at which it was received by vehicle identification number and stores it in the storage device 24.

At the time of departure, the automobile 11 is brought into an initial state, such as by pressing a zero return button to set the measured value of the travel meter 14 to zero, and starts operating. The center 16 is called at predetermined time intervals and the identification number and mileage are automatically sent. The center 16 organizes and stores the received mileage and time of reception by identification number. From the stored mileage and reception time, the time when the mileage on the operation schedule for that identification number has been passed is calculated, this is taken as the actual time, and the difference (shift) between this and the scheduled time is determined. Identification number and mileage (
The current position), scheduled time, actual time, and deviation are displayed in a table on the display 26. If necessary, if the actual time lags behind the scheduled time by a certain amount of time, for example 30 minutes or more, this will be detected and an alarm will be issued to call the attention of related parties.

In addition, each route is displayed with the name of the place it passes through and the line connecting them.
The current location of the car can also be displayed as a point on the line. Alternatively, the identification number, current location, actual time, and scheduled time are displayed for each route. It is also possible to display each passing point for one vehicle, the scheduled time for each passing point, the actual time, and the deviation.

Note that when managing one vehicle, there is no need to send the identification number. Instead of transmitting from the car at regular intervals, it may be transmitted at regular intervals.

"Effects of the Invention" As described above, according to the present invention, the current position on the route can be automatically determined at regular intervals. The delay from the scheduled time is automatically determined, and a display or warning 7 can be issued if the delay exceeds a predetermined value. A large number of vehicles can be managed simultaneously in real time. These operations can be performed automatically on both the vehicle side and the center side, with almost no human effort required.

Claims (1)

[Claims] (1) A system that manages the driving status of cars traveling on a predetermined route, in which the distance traveled from the starting point of the car is measured with an odometer, and the distance traveled for a certain distance or a certain period of time is measured by an automatic transmission device and a car phone. The vehicle mileage automatic system calls the center and sends the distance traveled up to that point, and the center stores the received mileage and the time it was received, and displays the current position of the vehicle and the deviation from the scheduled time. Report management system.
