The terminal station address is added to each terminal station 8 connected to 19 and signal transmission processing intended for meter reading is performed (solid line arrow B).

Then, as shown by a dotted arrow C, the reply is made to the pole-top slave station 5. Then, when the substation master station 2 receives the reply signal (indicated by the dotted arrow D) from the pole-top slave station 5, the series of processes is completed.
第１図のタイムチャートを第２図に示す。The time chart of FIG. 1 is shown in FIG.
変電所親局２は、各柱上子局５の制御下にある端末局８
を、ポーリング方式で順に呼び出し、検針処理を行な
う。The substation master station 2 is a terminal station 8 under the control of each pole-top slave station 5.
Are sequentially called by the polling method to perform meter reading processing.

で、その伝送速度は５０〜６０ビット／秒と極めて遅い
という特質があり、多数の需要家または端末局を一つず
つ走査するのには莫大な時間を必要とする。In particular, in the information transmission system using distribution lines, it is said that it is preferable to synchronize the signal transmission speed with the commercial frequency, so that the transmission speed is extremely slow at 50 to 60 bits / second, so that there are many demands. It takes an enormous amount of time to scan a house or a terminal station one by one.
また、配電線を利用した配電総合自動化装置において

列に実行させることができないという問題点があった。
そのため、つぎのような欠点を生じていた。Further, in the total distribution automation device using the distribution line, there is a problem that the processing cannot be executed in parallel because the conveyance system using the same signal path is used.
Therefore, the following drawbacks have occurred.

る。The substation master station 2 is a terminal station 8 under the control of each pole-top slave station 5.
Since the number of each of the pole stations is calculated, each pole station 5 calculates the processing time required to complete the meter reading processing of all the terminal stations 8 under the control of the station by the polling method, and A command for collecting the meter reading results is issued to the slave station 5.

Since the meter readings can be performed simultaneously in parallel, the processing time for meter reading can be greatly shortened, and the substation master station generates a transmission signal for the meter reading command and collection of individual meter reading results for each pole station. Therefore, there is a great effect that the time required for transmission can be shortened.

不要となる。In such a case, even if the contract time zone is changed for a specific customer, the substation master station 2 edits the address of the terminal station for the pillar-up slave station 5 that needs to be changed. By transmitting the functions and turning on the water heater control, changing the trip time, etc., and rewriting the rewritable non-volatile memory, it is possible to respond easily and quickly. However, no hardware support is required.

早期に検出することが可能となる。(C) Inspection of terminal station If the inspection of the terminal station 8 is performed from the substation master station 2 in a polling manner as in the conventional case, as described above, it is the same as the meter reading of the power consumption of the customer. However, there is a drawback that not only a great amount of time is required, but also a defect or abnormality of the terminal station cannot be detected early, but according to the present invention,
By installing a non-volatile rewritable memory in each post-slave station 5, it becomes possible to detect a defect in the terminal station at an early stage, as described below.

局の不良・異常点検を行なう。That is, when the pole station slave station 5 first receives the transmission signal from the substation master station 2 and analyzes the content of the reception, it determines that the station itself is not the target of operation (for a specific pole station slave station). DM
For switch control commands, etc.), check the terminal station under its own control for defects / abnormalities.
つまり、変電所親局２が操作の対象としている柱上子局
５は、その指示された処理を実行するが、当該柱上子局

８の不良・異常点検を実行する。That is, the pole station slave station 5, which is the target of operation of the substation master station 5, executes the instructed process, but all pole task slave stations other than the pole task slave station control the own station 8. Execute the defect / abnormality inspection of the terminal station 8 below.
前記の点検により不良・異常を検出した場合には、該点
検指令を発生した柱上子局５は、当該端末局のアドレス
と不良・異常内容を、不揮発性のメモリに書き込む。When a defect / abnormality is detected by the above inspection, the pole-side slave station 5 which has issued the inspection command writes the address of the terminal station and the defect / abnormality content in a non-volatile memory.
そして、当該柱上子局５が、例えば、変電所親局２から

て返信する。Then, when the pole station slave station 5 is designated as an operation target by the substation master station 2, for example, the pole station slave station 5 receives the operation result and the defective terminal station address (and, if necessary, Returns the contents of the defect / abnormality) to the substation master station 2.
なお、前記柱上子局５は、該端末局８の不具合現象が解
除されたことを確認したときは、メモリに書き込んだ点
検不良内容を消去する。When the pillar-top slave station 5 confirms that the trouble phenomenon of the terminal station 8 has been canceled, the pillar-top slave station 5 erases the inspection defect content written in the memory.

これによる伝送時間の短縮、ならびにこれらによる伝送
信頼度の向上を達成できるという、大きな効果がある。According to the present invention, as is apparent from the above description, regarding the meter reading of the power consumption of the consumer, the processing time is significantly shortened, the transmission signal transmitted from the substation master station is reduced, and the transmission by this is reduced. There is a great effect that the time can be shortened and the transmission reliability can be improved.

出することが可能となる。Further, according to the present invention, each pole-top slave station 5 checks the terminal station 8 under the control of its own station when the operation command is executed in parallel without affecting the operation command of the substation master station 2. Therefore, it becomes possible to positively detect the defect / abnormality of the terminal station 8 at an early stage.

な貢献をすることになる。Furthermore, systematic changes such as moving in and out of customers can be dealt with only by a command from the substation master station 2. In other words, it is possible to deal with the problem by simply rewriting the non-volatile memory provided in the pole-top slave station 5 without changing the hardware, which greatly contributes to cost saving. .
