Title: Method for controlling injection of chlorine in water purification plant
Inventor: KOBAYASHI TOSHIAKI
IPC: G05B11/32
Filed: 1984-02-24
Abstract: PURPOSE:To keep the concn. of residual chlorine constant by measuring the concn. of the chlorine in the treated water after chlorine injection, obtaining the deviation from the set value of a specified residual chlorine concn., and correcting the injection rate of chlorine with a PID operation. CONSTITUTION:The residual chlorine concn. PV of the treated water sampled after chlorine injection 6 is measured with a residual chlorine concn. meter 7, and the measured value is inputted to an arithmetic unit 8. The correction of the chlorine injection rate is carried out by FB control in the arithmetic unit 8 by using the deviation EV (EV=SV-PV) from the set value SV of the residual chlorine concn. After said calculation is carried out with a calculator 15, the final value of the chlorine injection rate is converted into the amt. of chlorine to be injected in accordance with the amt. of treated water measured with a flowmeter 10 which is inputted to an arithmetic unit 11. An appropriate amt. of chlorine to be injected can be maintained by controlling the opening degree of the valve of a chlorine injecting machine 12.

IPC: G06F3/00
Filed: 1988-02-17
Abstract: PURPOSE:To surely detect the abnormality by transferring the check data to the extension unit of the final stage via all extension bus signal lines to adversely transfer the check data again via said signal lines and comparing the transferred data and the adversely transferred data. CONSTITUTION:A selector 32 and a reception side control circuit 42 of an extension unit 9 of the final stage are set in a check processing state respectively by a check mode signal 37 of a control signal generating circuit 36 of a basic unit 1. The extension bus check data is written into a storage device 39 and at the same time sent onto an extension bus address signal line 34. The circuit 42 stores the bus check data into a reception data storage device 40. Then the data stored in the storage device 40 is sent again onto the line 34 and stored in a reread signal storage device 48. This data is compared with the check data stored in the storage device 39 by a comparator 49. If no coincidence is obtained from said comparison, a noncoincidence output signal 50 is activated. In such a way, the short circuit or the release of an extension bus signal line can be surely detected.
