Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a group education system that utilizes a personal computer or a hand belt computer.

[Conventional technology]

Recently, group education systems using personal computers or hand belt combinators have been developed as a means of group education in schools and the like.

[Problem that the invention seeks to solve]

Such systems typically utilize a dedicated computer with wired network capabilities or must be equipped with an expensive network controller. Moreover, these systems require that an operating system be designed each time to suit the purpose, which poses problems such as being expensive both in terms of cost and technology. In addition, the equipment is complicated and permanent, and it becomes an inflexible dedicated system, making it difficult to change the equipment, such as moving it or increasing or decreasing it.

In view of these points, it is an object of the present invention to form a wireless communication network, to simplify the configuration, to enable the movement of equipment, and to improve the efficiency and reliability of data transmission to each station.

[Means for solving problems]

The present invention for achieving the above object will be explained using drawings corresponding to embodiments. The group education device 1 of the present invention includes 1
a master station 2 and a plurality of slave stations 3a.

3b... and so on. However, all slave stations have the same structure, and will be simply referred to as 3 hereinafter.

The main station 2 includes a microcomputer section 5, a transmitting section 6, and a display terminal 7. The master station 2 is also equipped with a station address setting layer switch group 16 that enables simultaneous wireless transmission to multiple slave stations and forms a star-shaped network with the master station as the base, and the micro combinator unit 5 stores data for transmission. An element 9 is provided. Similar to the main station 2, the slave station 3 has a microcomputer section 5a, a transmitter section 6a, and a display terminal 7a.
It becomes more. Further, the slave station 3 is equipped with means for selecting its own address signal from among the address signals issued from the master station, and accepts the data signal sent together with the own address signal, and the combinator section 5a has a memory for temporarily storing this data. It includes an element 9a.

[Effect]

The main station 2 can check the transmission of data (educational materials) in the storage element 9 by being equipped with a terminal 7. Next, when transmitting this data to a plurality of stations, for example, all slave stations, it is transmitted together with an address signal common to all slave stations. Each slave station 3 receives this, temporarily stores it in the storage element 9a, and displays and learns it on the terminal 7a. Also, when the master station 2 sends communication or data to a specific slave station 3, it emits an address signal unique to that slave station, so only the slave station receives this signal, but other slave stations do not receive it, and therefore there is an error. It is possible to communicate with a specific slave station without causing any activation.

〔Example〕

FIG. 1 shows a block circuit diagram of a group education device 1 according to the present invention. This group education device 1 includes a main station 2 and a plurality of slave stations 3at3.

The main station 2 includes a microcomputer section 5, a transmitter/receiver section 6, a display terminal 7, and a metal part. The micro combinator section 5 includes a micro processor 7 feeder 8, a memory element 9, and an input/output section 10, and the memory element 9 stores necessary data (teaching materials). The transmitter/receiver unit 6 includes a transmitter/receiver 12 and a modulator/demodulator 13 for adding a data signal to radio waves or separating the data signal from the received radio waves, and the modulator/demodulator 13 connects the high frequency analog circuit and the digital circuit of the combiator. The input/output unit 10 is connected to the input/output unit 10 via the interface 14e for the purpose of the input/output unit 10. As the terminal device 7, a device having a display function such as an EVA personal computer or a hand belt computer is used.
Connected to 0. The input/output unit 10 is provided with a group of switches 16 for setting slave station addresses for selecting each slave station 3 and sending data money. This switch group 16ti each slave station 3a
.

Unique address switch A for each of 3b...
S, group address switch GAS.

The group address switch GAS is designed to send data to all slave stations at the same time, or to divide the slave stations into multiple groups and selectively send data to each group.For example, it sends data to all slave stations at the same time. When the group address switch GASt is pressed, a common address signal is issued to all slave stations. The input/output unit 10 further includes a communication status display E. This display E is used to notify whether the communication is abnormal or normal, and this can also be checked using the terminal 7. Although not shown, it is preferable to provide a reset switch, which is operated to return to the initial state.

M is a mode setting switch provided as necessary.

This is because the partition hood between data may be different depending on the maple type of the terminal 417 to be connected, and simply connecting via the converter 15 as described above may be inappropriate. 'J! It's meant to be used for a long time.

The slave station 3 has the same structure as the main station 2, and the same parts are given the suffix a and their explanation will be omitted.

However, the memory element 9a is for storing input data from the transmitting/receiving section 6a. Further, the microcomputer section 5 is fully equipped with an identification means 17 for identifying its own address signal, and although it stores data sent with its own address signal in the acceptance storage element 9a, it prevents acceptance of data sent with other address signals. . Note that the slave station 3 is capable of contacting only the master station 2, and the input/output section 10a omit the group address switch GAS mentioned above and is connected to the master station 2.
It is equipped with an address switch ASa for communicating with.

In FIG. 2, A and B are the microcomputer units in the master station 2, slave stations 3a, 3b, etc., respectively,
This is a main circuit storage box that houses the transmitter and receiver.

The embodiment of the present invention has the above-described configuration, and as an example of group training, the same data (teaching materials) are sent to all slave stations, and each slave station learns how to do so.

First, the transmission frequency of the master station 2 and the reception frequency of each slave station 3 are made to match. Next, the main station 2 selects the required data from the storage element 9 and checks it using the terminal 7. After that, press the group address switch GAS and all slave stations 3a
