Provided is an ecological cycle pig breeding method. The ecological cycle pig breeding method comprises the step of making wine and vinasse, the step of making vinasse feed, the step of breeding maggots through excrement, the step of carrying out ecological organic breeding, the step of using excrement to generate biogas, the step of utilizing excrement maggot breeding by-products, the step of producing organic feed and the like. According to the ecological cycle pig breeding method, the cost is reduced by 15% due to the vinasse feed, the cost is reduced by 15% due to feed with adult maggots, and the breeding cost is comprehensively reduced by more than 30%; protein feed is added; pig breeding cycle is short, and the slaughtering rate is high; health of live pigs is improved, and immunity is improved; the purposes of cycle breeding, cleaning production and zero emission are achieved, and environmental friendliness is achieved; products are various, original-ecology products such as the wine, the vinasse, organic live pigs, organic fly maggots, biogas and biogas slurry are obtained, the risk resistance capacity is high, and the ecological cycle pig breeding method is particularly applicable to ecological or organic live pig breeding of a single household, or large-scale and industrial live pig breeding. The ecological cycle pig breeding method is also applicable to ecological breeding of livestock and poultry such as cattle, horses, donkeys, deer, chickens, ducks and gooses. The ecological cycle pig breeding method is particularly applicable to ecological or organic live pig breeding of a single household or large-scale and industrial live pig breeding, and is convenient to demonstrate and popularize.

The invention relates to a jet flow noise active control test platform based on a scaled model of an engine nozzle, including a scaled model of a turbofan engine nozzle, an air supply system, a noise reduction test chamber, a noise spectrum measuring device, an electric valve and a controller . The size of the jet noise radiation is adjusted by the change of the micro-jet flow rate and the configuration and angle of the guide vane in the outer duct. The test piece is a scale model of the engine nozzle, including the nozzle test piece with micro-jet flow and Nozzle test pieces with various shrouded guide vane configurations. The air supply system adopts a screw air compressor and a high-pressure air tank. By adjusting the electric valve, the air and micro-jet flow into the inner and outer ducts are changed. The noise spectrum measuring device includes a noise spectrum measuring instrument, a microphone array and signal processing software, and online acquisition of sound signal processing and analysis. The scaled model of the nozzle and the noise spectrum measurement device are placed in the test chamber installed with sound-absorbing materials. Advantages: high flexibility, convenient test and low cost.

The invention provides a temperature-adjustable biological enzymolysis reactor, which relates to the technical field of biological enzymolysis. The temperature-adjustable biological enzymolysis reactor includes a heating tank, a baffle plate is fixedly connected to the inner side of the lower part of the heating tank, a first motor is fixedly connected to the bottom end of the heating tank, and an expansion element is fixedly connected to the top end of the bolt. The inside of the top of the heating tank is fixedly connected with a sealing groove, the top of the electric telescopic rod is fixedly connected with a top cover, the bottom of the top cover is fixedly connected with a sealing ring, and the inside of the housing is slidably connected with a reaction tank. The bottom ends of the two rotating shafts are fixedly connected with gears, and the gears are engaged with the ring gear. The front end of the second motor is fixedly connected with a cam and the cam and the reaction tank are attached to each other. The left end of the three-way valve is fixedly connected with the first guide tube. The bio-enzyme hydrolysis reactor can fully contact the biological enzyme with the reactant, thereby increasing the reaction rate, and the reactor has high reliability and anti-risk ability.

The invention discloses a method and system for network risk perception of a power monitoring system, relating to the technical field of network security, which collects network threat information perceived by multi-type or multi-vendor network security equipment at the network boundary of the power monitoring system, and performs network threat information on the network threat information. Analyze and calculate the accuracy of network threat identification, and display the current network threat information to users when the accuracy of network threat identification exceeds the threshold. The ability to perceive network risks does not depend on a single device or manufacturer, but on the composition of multiple devices The system has higher overall stability and stronger anti-risk ability, which solves the problem that the current power monitoring system's identification of network threats depends on the network security protection equipment at the network border to perceive network threats independently, and it is easy to miss network threats Or a wrong judgment, resulting in a technical problem that the power monitoring system's network risk identification ability is not high.
