The polarization curve at the junction point is prepared by the intelligent data collector, and the polarization intensity and interference status near the junction point can be clearly analyzed. Sample frequency can reach millisecond level. After matching with the long-acting polarization reference electrode, the potential change of the polarization test piece can be collected at the moment of power-on and power-off. The collected data can be uploaded to the network server through the built-in communication module (wired network or wireless network). The intelligent data collector at the junction point through the software management platform is mainly used for the collection of the pipeline potential value at the connection loop between the potentiostat and the pipeline (i.e. the energized junction point).

Function description: Intelligent networking function When the aggregation point intelligent data collector needs to upload data, the built-in central control unit will automatically open the GPRS remote communication channel; When the data is sent successfully, the control unit will automatically cut off the GPRS remote communication channel to reduce the network occupancy. The device also provides a standard RS485 port to facilitate data exchange with third-party intelligent devices. Multi-functional human-computer interaction confluence point Intelligent data collector has Bluetooth communication function, which can realize the human-computer interaction function of the device through intelligent mobile terminal (mobile phone or tablet computer), including parameter modification, data reading and storage, etc. Waveform recording function The sampling frequency of the intelligent data collector at the junction point can reach the millisecond level, which can be used to collect the potential change process of polarized test pieces at the moment of power-up and poweroff, and draw the depolarization curve at the junction point, which can be used to analyze the polarization process and interference status near the junction point. Multi-time sending function Through the mobile client or system management software (PC version), you can modify the online cycle of data communication, so that different devices send data according to the set time interval, to prevent network congestion; If you need to send data immediately, just press the "send" test button, and the data will be sent immediately.
