〔産業上の利用分野〕
この発明は、携帯用データ収集機を携帯してデータを収
集し、そのデータを中央処理装置に転送して、データの
処理、蓄積全行うデータ収集システムに関する。[Detailed description of the invention] [Industrial application field] This invention collects data by carrying a portable data collection device, transfers the data to a central processing unit, and processes and stores the data. Regarding data collection systems.

信速度も？ ６００ ｂｐｓ が限界であった。However, in the conventional data collection system, the portable data collection machines H1/~Hm' have an interface circuit for connecting to the central processing unit 1, and the interfaces for connecting to various central processing units are EIA
There was a drawback that it was not possible to achieve sufficient size and weight reduction and drip-proofness, which are required for interface circuits and connectors conforming to standards such as R8232C and R8422. In addition, the data collectors H1' to Hm' are assumed to be fully powered by batteries so that they can be used at all times, and in order to reduce the current consumption of the circuits, high-speed locking can be used, and the communication speed of the interface is also limited. The limit was 600 bps.
また、コネクターの着脱のくり返しによる信頼性の低下
も問題があった。There is also a problem of reduced reliability due to repeated attachment and detachment of the connector.
そこで、この発明は、従来のこのような欠点を解決する

ようにした。In order to solve all of the above problems, a stand-alone data relay device is placed between the portable data collector and the central processing unit, and the portable data collector and the central processing unit do not communicate directly, but each relays data. After all communication with the machine and the data was stored in the data repeater, the data was sent from the repeater to the other party. Communication between the portable data collector and the data repeater is carried out using an electromagnetic induction method using a coil.
The connector has been eliminated and the interface circuit has been completely simplified. Communication between the data relay machine and the central processing unit will be performed using a general-purpose E-engineer R8232C or R8422, and the data relay machine will be powered by AC power. use. By installing this data relay machine, the entire portable data collection machine was made smaller, lighter, and drip-proof, and the communication speed with the central processing unit was increased.

のデータの送受信が待たされるという問題が解決する。The data flow in the above system is that when all data is transmitted from a portable data collector to the central processing unit, the data collector and data relay machine have coils connected to each other, and due to their electromagnetic induction, the data is transmitted at a low speed such as 2400 bps. Transferring data from the collector to the data repeater The data is temporarily stored in the RAM in the data repeater, and then is transferred from the data repeater to the central processing unit at a high speed of 9600 bp8 or higher through a communication line. At this time, it is also possible to perform data formatting (FF) conversion. When all data is transferred from the central processing unit to the portable data collection device, the flow is reversed. The interface between the portable data collector and data repeater is on the coil inside the case.
There are no connectors, so it has excellent drip-proof properties, and there is no reduction in reliability due to twisting when connecting or disconnecting the connector. Since the communication speed is as low as 2400 bps, the clock frequency can be kept low throughout Europe, the current consumption is low, button-type adhesive batteries, etc. can be used, and the device can be made small and lightweight. 1. Because the communication between the central processing unit and the data repeater is high-speed, there are 4 lines to communicate with one portable data collector, and data cannot be sent and received from other portable data collectors. This solves the problem of having to wait.

The central processing unit 1 repeatedly checks whether or not there is data in the data relay machines 81 to Sn through the communication line, and transfers the data between the central processing unit 1 and the data relay machine S1 only when there is data. Transmission and reception are performed, and data from the portable data collector H1 is sent to the central processing unit f1. During this time, the other data machines $2 to Sn are prevented from communicating with the central processing unit 1.
