Remote, automatic control system for oil field fracturing pumping

ActiveCN101414171BMonitor and control operationsOrderly and stable operationTotal factory controlProgramme total factory controlAutomatic controlHuman–machine interface
The invention discloses a remote automatic control system of a fracturing pump skid used in an oil field. The system is used for remote automatic control of a well service pump skid and a truck-mounted skid used in the oil field; the remote automatic control system consists of a field control system which consists of Siemens S7-315 series PLCs which are taken as a core, a Siemens MP370 which is taken as a remote control human-machine interface, and Ethernet which is taken as a transmission media; the system can achieve remote control functions such as start, stop and emergency stop of an engine, gear shifting, braking, turning back to a neutral position and idle speed of a gearbox and the like, and the system can modify field running parameters in a remote manner, thus realizing bidirectional transmission between the pump skid and the human-machine interface (HMI); the Ethernet is taken for communication so that the pump skid can transmit the field data to a remote controller or a server at the speed of 100MB / S; an industrial exchanger is taken to connect the devices such as the PLC, the HMI and the like to achieve more group controls; the exchanger can convert the field data intothe data formats such as a standard *.CSV format and the like, and directly transmit the data to the server for data processing.

System and control method for automatically compounding cement paste

The invention discloses an automatic grout mixing system and the control method thereof. The invention is characterized in that the system comprises a micro processor (1); the micro processor (1) is connected with a man-machine interface (2), a hydro cylinder magnetic valve for dust-discharging valve (5) and a densitometer (4) respectively over a wire. The hydro cylinder magnetic valve for dust-discharging valve (5) is connected with the dust-discharging valve (3). An angular displacement sensor for dust-discharging valve (6) is arranged on the dust-discharging valve (3). The density of the grout can be controlled in the following procedures of collecting data, setting density, normalizing set density and actual density, interrupting the timing, adopting the current valve location of the dust-discharging valve as the antecedent of PID integrate, calculating the PID based on the result of the normalization of the set and actual density; adopting the difference between PID output value and the valve location of the dust-discharging valve as valve location deviation, comparing the valve location deviation with a dead area and the action of flow control over the hydro cylinder magnetic valve of the dust-discharging valve performed by an output switch. Therefore, the density of the grout can be accurately controlled. The automatic grout mixing system is easy to operate and can automatically control the dynamic density.

Electroencephalogram feature extracting method based on brain function network adjacent matrix decomposition

InactiveCN102722727AIgnore the relationshipIgnore coordinationCharacter and pattern recognitionMatrix decompositionSingular value decomposition
The invention relates to an electroencephalogram feature extracting method based on brain function network adjacent matrix decomposition. The current motion image electroencephalogram signal feature extraction algorithm mostly focuses on partially activating the qualitative and quantitative analysis of brain areas, and ignores the interrelation of the bran areas and the overall coordination. In light of a brain function network, and on the basis of complex brain network theory based on atlas analysis, the method comprises the steps of: firstly, establishing the brain function network through a multi-channel motion image electroencephalogram signal, secondly, carrying out singular value decomposition on the network adjacent matrix, thirdly, identifying a group of feature parameters based on the singular value obtained by the decomposition for showing the feature vector of the electroencephalogram signal, and fourthly, inputting the feature vector into a classifier of a supporting vector machine to complete the classification and identification of various motion image tasks. The method has a wide application prospect in the identification of a motion image task in the field of brain-machine interfaces.
