The invention discloses a method and a device for transmitting monitoring signal of a decomposer. The method comprises a group of decomposers in serial connection and a monitoring room arranged near the decomposers; the top part of each decomposer is provided with a data acquisition module with a data communication bus; all data of each decomposer is transmitted to the data acquisition module with the data communication bus; and the data acquisition modules with the data communication bus of the decomposers are connected in series and transmit the signal to the monitoring room near the decomposers by a bus communication cable. The method and the device for transmitting the monitoring signal of the decomposers, having the advantages of reliable operation and simple wiring, can solve the problems of big consumption of cable and serious signal attenuation and signal disturbance existing in the prior art, improve operational reliability of the decomposer, lower work load of maintainers, reduce construction amount in signal acquisition and signal transmission, and lower investment cost.
Description
technical field [0001] The invention relates to a method and device for transmitting monitoring signals of a decomposition tank, belonging to the field of electrical monitoring. Background technique [0002] In the alumina production workshop of the alumina factory, the decomposition tank is the main equipment for production. The height of the decomposition tank is generally more than 30 meters. Usually, 18 to 21 decomposition tanks are connected in series. The total length of the decomposition tank after series connection is about 300 ~ 400 meters, a stirring motor and other auxiliary equipment are installed on the top of each decomposition tank. In order to monitor the operation of each decomposition tank in real time, a data acquisition device is installed on the decomposition tank, which is responsible for collecting various signals during the operation of the electrolytic tank, such as whether the stirring motor is working normally, the flow rate, concentration, and Mo...
