The invention discloses a method for automatically switching a communication channel, aiming at solving the problems that the transmission efficiency of the existing emergency rescue command system in the single communication channel is seriously limited by the working state of the communication channel, and a worker can not easily select the optimal communication channel mode from multiple communication channels. The method comprises the following steps of firstly evaluating the transmission quality of the plurality of available communication channels to generate an evaluation result; determining the optimal communication channel according to the evaluation result; if information data need to be received and transmitted, automatically switching the optimal communication channel by a working channel; and giving the network parameters of the working channel to computers of the receiving part and the transmitting part to establish the communication link between the information receiving part and the information transmitting part. A cache device is also added into the method, and is used for carrying out breakpoint recording on the information data when a network is temporarily disconnected and carrying out breakpoint resume on the information data when the network is connected again; and after the transceiving process is finished once, the information data of the this time in the cache device are deleted.

The invention relates to the field of block chains, and discloses a fire-fighting monitoring method based on a block chain, and the method comprises a fire-fighting accident confirmation process, andthe fire-fighting accident confirmation process comprises the following steps: A1) a sensor detecting an abnormality, initiating an alarm, transmitting the alarm to the block chain, enabling a block chain center to initiate broadcasting, and notifying the block chain of the change; A2) carrying out analysis and alarming after receiving the broadcast by related on-duty programs or on-duty personnel; A3) judging whether an alarm is given out or not according to the specific situation, and if so, executing the step A4); otherwise, executing the step A5); A4) starting a fire accident emergency rescue process, and executing the step A6); A5) setting an alarm as a false alarm, setting the alarm on the block chain, executing the step A6); and A6) ending the process. The fire-fighting monitoring method based on the block chain has the following beneficial effects that distributed storage is realized, data is safer, records cannot be changed, falsification is avoided, data is public, the massescan execute supervision rights, and the automation degree is high.

The invention belongs to the technical field of smart home and particularly relates to a household swimming pool intelligent rescue device and a using method. The device comprises a central control unit, the central control unit is electrically connected with a network receiving unit, the network receiving unit is electrically connected with a mobile device, the central control unit is electrically connected with an alarm help-seeking unit, and the central control unit is electrically connected with an emergency rescue unit. According to the household swimming pool intelligent rescue device and the using method thereof, a fixed frame is installed on the inner bottom wall of a swimming pool body, a pull rod grid is mounted on the inner side wall of the fixed frame to lift a drowning person;meanwhile, the drowning person wears a mobile device, the drowning person manually triggers the mobile device, and a rescue signal is sent to the central control unit through the mobile device such that a conical rotor motor drives the pull rod grid to rise through a winch, then the drowning person is lifted, and therefore, the household swimming pool has the characteristic of facilitating the rescue of a household swimming pool user.

The invention discloses a city railway long and large interval tunnel evacuation method. The method is characterized in that after the urban railway vehicle breaks down in the tunnel section and losespower, whether a non-power system operates normally or not, whether a line can still run or not, and whether an adjacent line can still run or not are judged; aiming at different fault working conditions of urban railways, various corresponding evacuation modes are provided, the evacuation modes are comprehensive, a systematic solution is provided for solving the evacuation problem of large tunnel intervals of urban railways, especially urban railways interconnected and intercommunicated with national railways, an important role is played in guiding emergency rescue evacuation of the whole line, and a guarantee is provided for safe operation of the line.

The invention discloses a coal mine emergency rescue command information management system and a coal mine emergency rescue command information management method. The system comprises a fixed box, a draught fan, an electric brake, a pressure sensor, an electric lifting rod, a filter mask, a central processing box, and a display, the outer side wall of the fixed box is fixedly connected with a water pipe, the outer side wall of the water pipe is fixedly connected with a plurality of spraying heads, a limiting groove is formed in the outer side wall of the water pipe, an opening mechanism is slidably connected to the inner side wall of the limiting groove, the tail end of the opening mechanism is abutted with the inner side wall of the water pipe, a fixing plate is fixedly connected to the inner side wall of the fixed box, a positioning box is fixedly connected to the outer side wall of the fixing plate, the draught fan rotates to suck external smoke to the interior of the fixed box through a filtering groove, a filtering net is installed on the inner side wall of the filtering groove, filtering can be carried out on impurities in smoke dust, the smoke is exhausted through an exhaust groove, and therefore circulation of air in a coal mine is achieved, and the situation that due to smoke accumulation, workers are difficult to move is avoided.

The invention discloses an accident rescue scheduling method for a ship management system. The method comprises the following steps: inputting ship information in the ship management system in advance, and obtaining the position information of all ships inputted into the system in real time; after the ship alarm rescue information is received, the ship management system establishes a record according to the ship alarm rescue information to establish a rescue group, and adds ships within a preset distance near the ship sending the ship alarm rescue information to the rescue group; and sending the ship alarm rescue information and the ship information sending the ship alarm rescue information to a rescue group. The ship emergency rescue method has the advantages that in the emergency rescueprocess, the time for searching for the ship meeting the rescue requirement is shortened, related ships are contacted in time, rescue details are informed, and ship rescue is coordinated.
