Abstract: A method and a system for optimization to non-contact micro intelligent sensing in secondary DC loop potential are provided, including demodulating a weak AC current modulation signal through a demodulation circuit and amplifying the weak AC current modulation signal; amplifying the weak AC current modulation signal to output a stable and amplified measurable potential signal; processing the potential signal for noise to obtain a stable DC potential signal; inputting the DC potential signal to a comprehensive computing module for analysis and processing; using micro sensors to measure information. The measured potential results are input to the comprehensive computing module to analyze and correct, and the measurement results are output to the communication module for external output. The equipment is packaged to form a potential collection “probe” and a potential measurement “unit”. The potential measurement “unit” supports multiple potential collection “probes” for accessing.

Abstract: The invention discloses an intelligent operation and maintenance control platform and system for a secondary power system, belonging to field of power system operation and maintenance technology. The platform includes a interval layer, a transmission layer, a station control layer, a system layer, a platform layer, an application layer, and a disaster recovery backup centre. By collecting data from a security system and external information system, and sharing data with other application platforms of a secondary system, problems of omission, repetition, and isolation in current data collection are solved.

Abstract: A method for online monitoring of temperature in current terminal blocks based on thermal imaging are provided, including: obtaining real-time temperature distribution information of current terminals of a terminal box; using an external communication substation to upload the obtained real-time temperature distribution information to the secondary intelligent operation-and-maintenance control platform; determining whether there is an abnormality in temperature of the current terminals, if there is an abnormality, issuing an alarm message about potential danger for an open circuit of a current secondary circuit. The method provided by the present invention has a self-verification function of measurement data and can suppress the influence of ambient temperature.

Abstract: Examples techniques to communicate human field activities (HFA) requests to field operators are described. In an example, an HFA request corresponding to an operation to be performed by a field operator on an equipment in a facility is received. Based on the HFA request, an HFA command is generated using a pre-defined template. The HFA command specifies attributes of the equipment in a format compatible with a workflow management system that is implemented to manage standard operating procedures (SOPs) of the facility. The HFA command is transmitted to an application executing on a communication device of the field operator.

Abstract: Provided are a method for processing titanium extraction slag and a carbon extraction and dechlorination tailing. The method comprises the following steps that a titanium extraction slag raw material is ground to obtain a treated material with a particle size being 0.3˜120 ?m and d90?90 ?m; a first solvent and a treated material are mixed with a liquid-solid ratio of (3.5˜4.

Abstract: A full-tab cell production line includes a flattening unit (1), a gluing unit (2), a shell insertion unit (3), and a current collector welding unit (4) sequentially disposed in a processing direction. The flattening unit (1) includes an ultrasonic flattening sub-unit (11) and a mechanical flattening sub-unit (12). The ultrasonic flattening sub-unit (11) performs ultrasonic flattening pretreatment on an end surface of a core. The mechanical flattening sub-unit (12) is configured to mechanical flatten the end surface of the core that has undergone the flattening pre-treatment. The gluing unit (2) is configured to wrap an insulation tape around the flattened core. The shell insertion unit (3) presses the core wrapped with the insulation tape into a shell. The current collector welding unit (4) welds the current collector to two ends of a core, welds collector plates to two ends of a core that has been inserted in the shell, and bends a tab to a pre-determined angle.
