This application discloses a hoisting winch for emergency recovery operations of manned submersibles, which includes a hoisting winch assembly and a hydraulic motor. The hoisting winch assembly includes: an annular boss is arranged on the drum, and a second A bearing cover plate, a blind hole is arranged above the first bearing cover plate; multiple thin-walled bearings are arranged side by side, the bearing inner ring of the thin-walled bearing is installed above the annular boss, and the bearing outer ring of the thin-walled bearing is installed on the pulley Below, the connection between the inner ring of the thin-walled bearing and the annular boss is a single-side shoulder positioning method; the left side of the pulley is provided with a threaded long hole, and a set screw pin is installed in the threaded long hole. After the fixed screw pin is screwed out of the blind hole, the pulley can rotate on the reel; the second bearing cover plate is installed on the right side of the pulley to limit the thin-walled bearing. Through the technical solution in this application, the pulleys used for emergency recovery are integrated on the reel of the existing hoisting winch, so as to improve the safety and efficiency of emergency recovery of the submersible.

The present application discloses a multifunctional lifting winch for manned submersible recovery operations, including a lifting winch assembly, a reducer, a hydraulic motor, and a hydraulic control system. The hydraulic motor is connected to the first pipeline and the second pipeline of the hydraulic control system. Pipeline, the hydraulic control system includes: winch control valve group and accumulator valve group; winch control valve group includes: the output ends of the solenoid valve are respectively connected to the first pipeline and the second pipeline, and the input ends of the solenoid valve are respectively connected to The balance valve is connected in series with the second pipeline, the pilot control valve of the balance valve is connected with the first pipeline, and the proportional relief valve is connected in parallel between the first pipeline and the second pipeline; The accumulator valve group includes a pressure reducing valve, a sequence valve and two accumulators arranged in parallel, and the accumulator valve group is used for supplementing oil to the first pipeline and the second pipeline. Through the technical solution in the application, the constant tension pretension of the cable in the hoisting winch is realized, and the impact impact when the submersible leaves the sea surface is reduced.

An underground working personnel emergency rescue guiding system and a guiding method are provided, so safety management personnel can timely learn about underground personnel distribution conditions, early warning can be timely send to underground people and an effectively escape route can be timely provided for underground personnel when danger happens, thus effectively reducing personnel casualty and economic losses, and improving mine enterprise safety production level; the guiding system comprises a host computer, a fiber communication device, a communication substation, an information miner light, an audible-visual annunciator, an escape guiding screen and a power supply; the guiding method comprises the following steps: the host computer receives people monitoring data from the communication substation through the fiber communication device, and sends short message data, alarm data and escape guiding data to the communication substation; the communication substation sends the short message data to the information miner light, and respectively transfers acousto-optic alarm data and escape guiding data to the audible-visual annunciator and escape guiding screen; the underground working personnel wear the information miner light, send communication codes identifying IDs to the communication substation, and receive the early warning information and the guiding route from the communication substation.

The invention discloses a method for setting emergency rescue parking points of urban rail transit stations, which quantifies the importance of transfer, location and level of the station based on the transfer passenger flow, location passenger flow and daily passenger flow respectively, and then quantifies the traffic of the station importance. Finally, according to the traffic importance value, the minimum number of parking points required to be covered by the target station is set, which is conducive to the site selection and setting of emergency rescue parking points, reduces emergency delays of rescue vehicles, and improves emergency rescue efficiency.

The invention discloses a method for planning an emergency rescue route for urban road traffic accidents, comprising the steps of: 1) generating a topological structure diagram of an urban road network, acquiring traffic flow data and rescue start and end point information; 2) analyzing the characteristics of emergency rescue for urban road traffic accidents , select the appropriate evaluation index for the rescue path planning method; 3) Construct the basic framework of timing co-evolution path planning, and systematically explain the optimization principle of timing co-evolution path planning; 4) Design a suitable solution algorithm in combination with the operating characteristics of urban road vehicles; 5 ) Clarify the calculation method of the uncertainty factors in the actual traffic environment of the urban road network; 6) Output the rescue path planning results through computer programming. The invention can solve the problem of urban road emergency rescue path planning.

The invention provides a beidou-satellite-communication-based emergency rescue method. The method comprises: a neighbor reference table including a plurality of beidou IDs associated with each other is established, wherein the neighbor reference table includes historical positioning rescue information corresponding to the plurality of beidou IDs and the positioning rescue information includes the beidou IDs, position information, help information, and positioning time; if a neighbor query request exists in the received help information, beidou IDs that are associated with the received beidou ID and historical positioning rescue information are obtained; according to historical positioning rescue information and the received position information and positioning time, a position offset and a positioning time offset are determined, and if the position offset and the time offset are less than a predetermine threshold value, historical positioning rescue information is determined as a neighbor positioning rescue information; and the neighbor positioning rescue information is fed back to a beidou terminal. in addition, the invention also provides a beidou-satellite-communication-based emergency rescue system, thereby realizing friendly neighborhood and mutual assistance in an area with no coverage of a communication network signal.
