Abstract

PURPOSE:To divide a data according to whether it is urgently required or not and to send the data by transmitting the data through the use of radio equipment and adopting the transmission system of the contention system or the polling system depending on the content of the data. CONSTITUTION:A cargo collection request from a shipper is received by a phone call, a cargo collection reception terminal equipment 1 receives a required data, stored in a host computer 2, to which truck the data is to be sent is discriminated, the data is edited in a data transmission format and the transmission processing is applied to a base station radio equipment 4 by the contention system. The transmission information from a driver to a center manager is acknowledge information to the cargo collection request and truck status information, the data is sent from an on-vehicle terminal equipment input/output device 7 and a mobile station radio equipment 6 discriminates whether the system is the contention system or the polling system and the data is sent in a route of base station radio equipment 4 host computer 2. Thus, the data is shared into the required data and unrequired data immediately and the resulting data is sent.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a collection instruction system for collecting cargo by truck.

[Conventional technology]

Conventional collection instruction systems have introduced in-vehicle terminals, but they only transmit using the contention method.
Either only the minimum amount of data required is sent and received, or the number of in-vehicle terminals that can send and receive data to and from the host system is limited.

[Problem to be solved by the invention]

In the case of the contention method of the conventional collection instruction system described above, in order to transmit data from one host computer to hundreds of in-vehicle terminals, at a minimum, only the collection instruction data from the host computer can be transmitted. There is a drawback.

[Means to solve the problem]

The collection instruction system of the present invention includes a host computer that centrally manages collection instruction data creation and transmission and truck status, a wireless device that actually transmits and receives data between the host computer and an on-vehicle terminal, and a display that displays the collection instruction data. It consists of an in-vehicle terminal device with a keyboard that transmits the current status of the pickup from the host computer to the in-vehicle terminal, and the in-vehicle terminal also transmits understanding information for the pickup instruction data and current truck conditions to the host computer. It is characterized by being transmitted to.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, and FIG. 2 is a block diagram showing an in-vehicle terminal in FIG. 1.

In this collection instruction system, a collection request from a shipper is received by phone, the necessary data is inputted from a collection reception terminal 1, the data is stored in a host computer 2, it is determined which truck to send to, and the data is converted into a data transmission format. After editing, the contention method (by adding a contention method transmission code to the data on the host computer 2, the code is judged on the base station radio 4 and data transmission is performed in real time), Base station radio 4
Performs transmission processing for. The base station radio 4 determines the data received from the host computer 2 and transmits the data to the corresponding mobile station radio 6. The mobile station radio 6 transmits the received pickup instruction to the on-vehicle terminal input/output device 7, and immediately displays the data on the display 71 and sounds the buzzer, so that the driver can be notified of the request from the shipper in a short time.

The information transmitted from the driver to the center manager is information regarding the acceptance of the pickup request and information on the truck's movement status (such as "Departure", "Complete", "Inside", and "End"), and the data transmission is carried out using the onboard terminal. Output device [sent from 7,
On the mobile station radio 6, the contention method or the polling method (until there is a data reception request from the base station radio 4,
If the data is not transmitted to the base station radio 4 and the data is stored, then the data is transmitted from the base station radio 4 to the host computer 2. If the data is sent by polling method, the data is stored from the base station radio 4. The number of data reception requests to the mobile station radio 6 can be freely controlled by instructions from the host computer 2. The host computer 2 (which can receive the information whenever necessary) displays the truck movement status and collection status on the status display terminal 3 at any time, making it easy to manage the center and grasp the truck movement status and collection status.

〔Effect of the invention〕

As explained above, the present invention transmits data using a wireless device and employs two transmission methods, contention method and polling method, depending on the data content, so that data that is immediately necessary and data that is not immediately It can be sent by sorting, improving the accuracy of pickup instructions, and
This has the effect that the track status on the host computer can be centrally managed.

Claims (1)

[Claims] Using dedicated radio waves, data is sent and received between the host system, which stores collection request data from shippers over the phone, and distributes and edits the collection request data on a truck-by-truck basis, using dedicated radio waves. Considering the real-time nature of the data to be transmitted within the in-vehicle terminal system, data that is urgently needed is transmitted using the contention method, and other data is transmitted using the polling method. A collection instruction system, characterized in that the load on the dedicated radio waves is reduced by switching between a polling method and a polling method.
