The embodiment of the invention provides a method and device for switching main equipment and standby equipment in a hot standby environment. The method comprises the following steps of determining toreceive the flow statistics information sent by the standby equipment; judging the current state of the main equipment; and determining whether to switch from the master device to a standby device based on the determined result and the current state of the master device.

The invention discloses a text typesetting method for a web page, comprising: in response to a switching operation of the language type of the web page, extracting text content, image objects and position information of the image objects in the web page pictures of the web page; according to the current language to be switched to Type, convert the text content to the language type to obtain the converted text content; determine the converted text content corresponding to the image object; determine the typesetting area of ​​the converted text content according to the image object and its location information; The text content is typeset in the corresponding typesetting area. The invention also discloses a webpage text typesetting device, equipment and storage medium, which can rearrange the text content of the webpage image by confirming the image object and position information of the image, so that the language type of the text content in the webpage image can be changed. Can be converted and typeset in a reasonable position.

The invention discloses a butterfly valve pneumatic redundant system used for rocket launching water spraying and a control method thereof. A gas tank, a first electromagnetic valve set, a first one-way valve and a pneumatic device in the system are sequentially connected, and a normal-state air supply passage is formed; the gas tank, a second electromagnetic valve set, a second one-way valve and the pneumatic device are sequentially connected, and a fault-state air supply passage is formed; the pneumatic device is connected with a butterfly valve; the method comprises the steps that S1, three-position four-way electromagnetic valves A and C are kept closed, and a three-position four-way electromagnetic valve B is kept opened; S2, whether a three-position four-way electromagnetic valve A is normal or not is detected, if the valve A is normal, the step S3 is executed, and if the valve A is not normal, the step S4 is executed; S3, through the normal-state air supply passage, air is supplied to the pneumatic device; S4, through the fault-state air supply passage, the air is supplied to the pneumatic device. the effective combination and redundant control scheme of the electromagnetic valves can be creatively developed, in-time response of the butterfly valve can be ensured, and reliability of the action of the butterfly valve used for rocket launching water spraying is greatly improved.

The invention relates to a method for switching independent operation micro-grid master control power sources and belongs to the field of micro-grid control technologies. Under the condition that at least two power generators exist in a micro-grid system and can serve as the master control power sources, the method can achieve rapid and reasonable switching of the master control power sources during the independent operation of a micro-grid according to distributed type generated output conditions, load conditions, master control power source conditions and energy storage conditions. In addition, while the micro-grid supplies power stably and safely, distributed type power generation is utilized to the maximum, fuel cost is saved, and environment pollution is reduced.
