Method for remotely and dynamically monitoring electric energy metering load

ActiveCN101950008AAdminister and use accuratelyEnsure accuracy and fairnessError preventionElectrical measurementsModularityInternet transit
The invention discloses a method for remotely and dynamically monitoring electric energy metering load. The method comprises the following steps of: (1) modularly encapsulating data according to the difference of operation frequency and monitoring authority to build a header, a CRC and a split key which correspond to the data; (2) transmitting an encapsulated data packet to a background processor authorized by an allocation level through the internet, wherein the background processor splits the modular data packet according to the authority of an operation key, the verification of the data CRC and the verification of the split key, and performs the CRC verification and the fault tolerance processing on the split data; (3) building a matched data processing mode to correspond to the data packet one-to-one according to the operation frequency; and (4) processing, backing up and reporting abnormal data in a way of combining an arbitrating mechanism with self-healing capacity. By the method for remotely and dynamically monitoring the electric energy metering load, the management and the use of the electric energy metering load are more accurate, quicker and more effective, and the accuracy and the justification of electricity user checking are guaranteed.

Measuring method for displacement efficiency of simulated well cementation cementing

ActiveCN103556986AReal shootingReal recordSurveyFluid speed measurementWell cementingCcd camera
The invention relates to a measuring method for displacement efficiency of simulated well cementation cementing, which comprises the following steps: 1) taking a PIV (Particle Image Velocimetry) system as a measuring device; 2) respectively injecting a displaced solution and a displacing solution into a simulated shaft and distributing tracer particles in a displacing solution flow field; 3) causing the tracer particles to generate scattered light through a laser of the PIV system, and shooting and recording the positions of the tracer particles in the flow field in real time by using a CCD (Charge Coupled Device) camera of the PIV system; 4) obtaining a moving image of the tracer particles in the flow field, selecting a group at equal intervals from the moving image as analysis identifying information, and obtaining the areas occupied by the tracer particles in different time periods in an annular cross section of the simulated shaft; 5) obtaining the displacement efficiency of the displacing solution for the displaced solution in a certain time period according to the total area of the annular cross section of the simulated shaft and the data obtained through analysis identification; and 6) drawing a displacement efficiency graph through the obtained displacement efficiency in the simulated shaft in different time periods, thereby obtaining the whole displacement efficiency in the simulated shaft.
