Description

Detailed Description of the Invention 10 Technical Field of the Invention The present invention relates to a vehicle operation management system for each vehicle that transports raw materials such as ready-mixed concrete and asphalt concrete (hereinafter referred to as "asphalt concrete") to a site, and in particular, -Relates to a vehicle management device that uses a channel access system (hereinafter referred to as ``MCA system'') and allows you to check the dynamic display of a vehicle on a screen.

b. Prior Art In order to supply raw materials such as ready-mixed concrete and asphalt concrete to consumers at the best possible quality and at a reasonable price, it is necessary to improve the efficiency of transportation as a future issue. Up until now, factors that have lowered the quality of raw materials such as ready-mixed concrete include the transportation time required from the factory to the site. Exceeding the transportation time or the original schedule will lead to a decline in the quality of ready-mixed concrete. Therefore, it has been confirmed from experience that the more accurate the scheduled time, the better the quality of ready-mixed concrete will be. In addition, deterioration in the quality of chemical feces also occurs on-site. In other words, the quality of ready-mixed concrete deteriorates due to the waiting time caused by the next vehicle arriving while the preceding vehicle is unloading.

In this case, the waiting time will have the same effect on other vehicles,
They also have disadvantages, such as lowering the quality of each other and requiring extra vehicles.

Therefore, transportation time and waiting time affect the number of vehicles allocated, and if the operation management of vehicle allocation is appropriate, there will be fewer idle vehicles, and it will be possible to reduce the number of vehicles owned.

Conventionally, the ability to report status by telephone has been adopted as a means of managing the operation of vehicles at factories, each vehicle allocation, and between sites.

However, there were concerns that managing vehicle operations using telephones could annoy drivers and lead to accidents due to carelessness. In addition to the problem of radio frequency limitations with conventional commercial radio stations and simple radio stations, there was also the problem that they could not be used for real-time digital communication or data. .

C9 Purpose of the Present Invention The purpose of the present invention is to solve the above-mentioned conventional problems.In particular, by utilizing the newly appeared MCA system, the dynamic display confirmation of the vehicle (the related operation processing is performed by the MCA system). This vehicle operation is realized by using radio equipment and computers, and enables better management of factories and sites, supplies raw materials such as high-quality and reasonably priced ready-mixed concrete and ascon, etc. to consumers, and increases the efficiency of transportation. The purpose is to provide a management device.

d. Embodiment First, before going into the explanation of the drawings, an overview of the vehicle operation management system according to the present invention will be explained.

This system uses the MCA system to wirelessly link the plant factory, a vehicle @ (for example, a mixer truck), and the field, and based on wireless digital data transmission, makes full use of radio equipment and computers to control the vehicle. Dynamic display (for example, vehicle number, current position of the vehicle, distinction between actual vehicle, empty vehicle, working and waiting, factory and on-site departure and arrival times, etc.) can be confirmed on the CRT display screen at the factory. It is. An example will be explained below with reference to the drawings.

FIG. 1 is a block configuration diagram of an example of a vehicle operation management system according to the present invention. A high-precision microprocessor is employed, and all communications with mobile radios on the mixer truck side are carried out via the base station 10. Mobile radio based on MCA is used as the transmission/reception method, and the service area is usually a zone within the range of 30 Kr'rL'. A frequency band of 800 MHz is used. Reference numeral 2 is an interface for connecting a small computer and the radio device 1, and 3 is a small computer that stores digital data wirelessly transmitted from each mixer truck and performs arithmetic processing based on this digital data. Mainly, this small computer executes various calculations related to the vehicle operation status based on vehicle data and field data, such as round trip or return calculation, distance calculation on the screen, and situation representation. The small computer 3 is, for example, a central processing unit (CP).
U), contains memory (eg ROM1RAM) and acts as a data processor. Vehicle data is transmitted digitally and wirelessly from the mixer truck side as a signal based on a specific key operation by an operator (usually the vehicle driver) or a detection signal from a mixer drum rotation sensor, travel sensor, etc. The small computer 3 is equipped with a display 4 for displaying the vehicle operation status on the screen in real time based on data from each mixer truck, for example, a CRT.
It's a disphray. The layout of the screen is detailed in FIG. A floppy disk 5 stores various data such as a communication file 1 and a performance file as files. Further, this device is provided with a built-in modem (not shown) and a keyboard 6. The keyboard 6 consists of two types of standard keyboard and intelligent keyboard.
The standard keyboard is equipped with JIS keyboard layout data keys (alphanumeric keys, etc.), a numeric keypad for numeric data input, and a function key.Key functions include shifting between alphanumeric characters, symbols, and kanji and kanji.
Screen control such as cursor and scrolling, print function,
Various control key functions, e.g. stop key, BAS I
It has an interrupt key that serves as a command input wait signal for C. Furthermore, the intelligent keyboard has a mat key that allows one-touch input of item data specified by the key mat by attaching the key mat, and has a numeric keypad and function keys similar to a standard keyboard. In addition, the MCA system can be used to check the dynamic display of the axle, and it can also be realized by a processing computer related to operation that performs data management and record management of various forms. That is, - Reports such as daily transportation reports can be created by batch processing using data and files from each mixer truck. On the other hand, the mixer truck 7 is equipped with a mobile radio device 8 based on the MCA system, and the radio device is connected to a control section 9 and a data processing section 10, and outputs processed data from various sensors. Furthermore, the mixer truck has a built-in clock that keeps track of the time, and the distance traveled is detected by a travel sensor, a so-called rotation sensor. That is, all vehicle data is wirelessly transmitted as digital data from operator operations or sensor detection signals from the mixer truck. An example of vehicle data content is as follows.
