The invention discloses a crowd behavior simulation method and a crowd behavior simulation system guided by a safety evacuation mark. The method comprises the following steps of: creating a three-dimensional building model of a scene to be simulated; determining the quantity and the position of the exit corresponding to the scene to be simulated in the three-dimensional building model; marking thelocation of safety evacuation signs corresponding to the scene to be simulated in the three-dimensional building model; according to the number of exits, the location of exits and the location of safety evacuation signs, the road markers in the three-dimensional building model being set in advance, and then PRM algorithm being used to generate all the available evacuation paths, and the paths inthe planning direction of safety exit being marked as one-way paths, paths beyond the planning direction of the safe exit being marked as one-way paths to the outbound exit; importing characteristic data of initializing evacuation crowd; a Dijkstra algorithm being used to find the shortest escape path from the one-way path for the evacuated individuals; in the process of crowd evacuation, an RVO obstacle avoidance strategy being used to simulate crowd evacuation.

The invention belongs to the technical field of touch control, and provides a handheld touch control device. At least one side face or the back face of the handheld touch control device is provided with a touch sensing assembly. The touch sensing assembly comprises a holding portion and an operating portion, wherein the holding portion is used for sensing handheld actions, and the operating portion is triggered by the holding portion to work. The operating portion is used for sensing clicking and sliding actions to achieve target operations of one or any two or three of movement of application programs on an operation interface, power on-off and volume adjustment. The touch sensing assembly is arranged on one side face or the back face of the handheld touch control device and can recognize sliding or clicking operations of a user, then the functions of power on-off, volume adjustment, application program movement and the like are achieved, and one-hand holding operation of the touch control device of the large size is facilitated; due to the fact that the touch sensing assemblies are arranged on the two sides of the touch control device, holding by the left hand and holding by the right hand can be effectively recognized, the handheld touch control device is suitable for using habits of different crowds, and the using flexibility of the touch control device is improved.

The invention discloses a quick estimation and three-dimensional display method for visual green land areas of city floors. The method comprises the following steps of 1) calling a building layered modeling algorithm to perform base contour extraction and automated three-dimensional modeling on building digital surface model data so as to generate corresponding Shp graphic layer and Multipatch model; 2) calling a floor visual green land estimation algorithm to perform ornamental green land area automatic estimation on extracted building floors; 3) updating attribute fields of a building three-dimensional model and a building base contour model, and performing layered color-setting display. According to the method, a vertical city visual green land analysis concept is innovatively proposed, automated estimation and quick modeling display functions are realized at the same time, and manpower cost of actual measurement is reduced; and the method meets partial demands of people such as city residents, city planners, decision makers, house dealers and the like in related aspects of green landscapes, and has a certain social benefit and economic value.

The embodiment of the invention discloses a processing method of an access request. The method comprises the following steps: receiving the access request from a terminal, and acquiring physical signinformation of a user of the terminal according to the access request; acquiring an access rule corresponding to the physical sign of special population when the physical sign information meets the preset physical sign of the special population, and determining the acquired access rule as the access rule of the user of the terminal; determining the access rule of the user of the terminal accordingto the physical sign information of the user of the terminal when the physical sign information runs counter to the physical sign of special population; responding to the access request of the user according to the determined access rule of the user of the terminal so as to obtain the response content of the user of the terminal, and sending the response content to the terminal. The embodiment ofthe invention further discloses a processing device of the access request, a home cloud server and a computer readable storage medium at the same time; the existing loss caused by unconscious misoperation on the terminal by the special population is eliminated, and the network operation security is improved.

The invention discloses a health food for recovering physical ability. The health food is characterized by comprising the following materials in parts by weight: 30-35 parts of laver, 11-16 parts of folium isatidis, 12-13 parts of broccoli, 2-6 parts of lemon, 1-2 parts of pear, 0.1-0.2 part of phenylalanine, 0.2-0.6 part of valine, 3-5 parts of camellia oleosa seed oil, 2-4 parts of palm oil, 3-6 parts of wheat flour, 15-20 parts of soybean meal, 0.5-0.9 part of a food preservative and 5-8 parts of American ginseng. The invention provides a formula for the health food for quickly recovering physical ability; the novel health food which is efficient, low in toxic effects, and free of side effects is prepared by using traditional Chinese medicines with homology of medicine and food as raw materials through traditional Chinese medicine modernized standard process flow. In the present time with super-high proportion of sub-health crowd, the compound food is super-high in market prospect and economic value.
