Abstract. This paper introduces a temperature of copper electrolyzer and voltage acquisition system
which is divided into three layers, lower computer collects cell temperature and voltage using
MCIMX287CVM4B, then sent to the gateway basing on the MCIMX287CVM4B through wireless
network, in the end the gateway transfers data to the host computer via CAN bus. The paper also
introduces the method to solve the general design scheme of the system and key technology. The
system has high accuracy, good stability, a higher value and promotional value.
Introduction
In copper electrolysis production, electrolyte temperature and voltage on the cell has close
relationship with production quality, technology personnel need to adjust process parameter
according to the temperature of electrolyte and voltage of electrolyzer. The traditional production, in
order to grasp the temperature of electrolyte and voltage of electrolyzes, production personnel to the
scene with the instrument need timing manual measurement the temperature and voltage, Electrolytic
cell number as many as hundreds of thousands of workshop, and the groove surface of high
temperature, acidic liquid corrosion resistance, poor working conditions, Each electrolytic cell
measurements again is a time-consuming and laborious work, and this measurement is difficult to
reflect the parameters of electrolyzes cell in time.
The voltage at both ends of the cell referred to as ‘cell voltage’, cell voltage is another parameter
that relevant to electrolytical copper quality, change of cell voltage reflects the electrolytic conditions
of electrolytic cell. According to the change of cell voltage, can determine whether the existence of
the cathode plate and the anode plate short circuit condition, whether the presence of copper electrode
poor contact conditions. Electrolytic copper production process, in order to discover short plate,
production personnel need regular drag on the groove face Gauss meter, which is also a difficult and
tedious work, spend a lot of labor costs.
The voltage and temperature acquisition system of electrolytic cell , is proposed in this paper can
be real-time and efficient acquisition of production process the data needed, greatly reduce the labor
intensity of workers, improves the production efficiency.
This system consists of three parts: data acquisition node, communication gateway, host computer.
The system structure is shown in figure 1. By the 64 detection device (data acquisition), the
8 gateway, a CAN bus communication card and a host component. Each detector means for
measuring the parameters of eight electrolytic cell , each gateway is responsible for eight detection
device, the host and the gateway through the CAN bus connection.
