The invention discloses inner column type umbrella-shaped expanding equipment and an expanding method thereof. The inner column type umbrella-shaped expanding equipment comprises an umbrella-shaped expanding device and a plurality of longitudinally-distributed inner columns; and the inner columns are pressure-bearing columns I or telescopic pressure-bearing columns or telescopic pull rods; when the number of the inner column is one, the inner column is located on the central axis of the umbrella-shaped folding rod set; when the number of the inner columns is larger than or equal to two, the multiple inner columns are distributed around the central axis of the umbrella-shaped expanding body device; the inner columns are combined or independently arranged; the combined arrangement of the inner columns comprises combined arrangement of a tie bar disc and the front end of the inner column and / or combined arrangement of a tie bar penetrating disc and the rear end of the inner column; when the inner columns are the pressure-bearing columns I, one ends of the pressure-bearing columns I are hinged to the front ends or the rear ends of all the folding rods, and the other ends of the pressure-bearing columns I are located between the front end and the rear end of the umbrella-shaped folding rod set; and when the inner columns are the telescopic pressure-bearing columns or the telescopicpull rods, the two ends of the telescopic pressure-bearing columns or the telescopic pull rods are fixedly connected with the front end and the rear end of the umbrella-shaped folding rod set respectively. The inner column type umbrella-shaped expanding equipment and the expanding method thereof are used for achieving the purpose of optimizing the pre-collection type three-hinge pressure-bearing structure.

The invention relates to a energy-saving integrated window which can be pushed, drawn, horizontally opened and rotated in 360 degrees, belonging to construction door and window areas. Compared to present technique, it comprises a window frame and a window leaf. It is characterized in that: the sections of upper and lower frames have roller directional slide track (25) inside which a slide track integration is arranged; the upper and lower slide integration has a rotate axle (22); the window leaf (3) is mounted between upper and lower slide integrations via rotational axle (22). The invention can be pushed, drawn, horizontally opened, and rotated in 360 degrees, to apply the cleaning on the glass, with better lighting property and safe usage.

The present invention relates to a preparation method of a safe firing cable of firecrackers. In the method, yarn is used as a carrier to infuse the following medicines, which are used raw materials, according to the following steps. The medicines comprise potassium perchlorate, potassium terephthalic acid, ammonium dichromate, polyethylene alcohol, moisture resistant agent, charcoal and sulfur. The method has the following steps: the potassium perchlorate, the potassium terephthalic acid, the ammonium dichromate, the charcoal, the sulfur and the polyethylene alcohol are arranged in a container according to the weight ratio; water with a certain proportion is added into the container; the mixture is stirred so that the medicines can be dissolved in the water; then the moisture resistant agent is added; and the mixture is mixed well; the yarn is infused in the container, taken out and then sent to a drying device to be dried; thus the safe firing cable can be prepared. In the method, the yarn is used as the carrier to infuse the medicines of the firing cable; the production is simple; the amount of the medicines is reduced; the method is safe; and the cost is reduced. The application of the potassium perchlorate has the advantages of low oxygen content, low decomposition temperature, excellent stability and low sensitivity. Thus the application of the potassium perchlorate is superior to the application of potassium chlorate. The firing cable solves the problems of storage, transportation and insecurity in use.

The invention provides a communication method, a communication device and a communication system for a set top box. The method comprises the following steps of: sending a communication request connected to target equipment to a server, wherein the communication request comprises an equipment mark of the target equipment; receiving a random code returned from the server and target equipment address information corresponding to the equipment mark; and conducting encryption communication between the target equipment address information and the target equipment based on the random code encryption communication data. By the method, the device and the system, the communication security is greatly improved.
