The invention discloses a method for monitoring running states of vehicles in a tunnel. The method comprises the following steps: (1) monitoring vehicles entering in a tunnel, tracking running states of the vehicles, and converting monitoring signals into electrical signals; (2) receiving and processing the monitoring signals; and (3) displaying the processed running state signals of the vehicles in the tunnel at a conspicuous position of an entrance of the tunnel in order to warn drivers coming into the tunnel of selecting running lanes and adjusting running speeds. According to the method provided by the invention, the running states of the vehicles in the tunnel are monitored, the running states of the vehicles are converted into the electrical signals and the electrical signals are processed, and vehicle speed signals and signals of distance between vehicles and the entrance of the tunnel which influence the running safety are displayed at a conspicuous warning display screen of the entrance of the tunnel in order to warn the drivers coming into the tunnel of notifying the running states of the vehicles in the tunnel, thereby guaranteeing the running safety of the vehicles. The invention also provides a monitoring device of the method for monitoring running states of vehicles in the tunnel.

The invention provides an early warning system and an early warning method for abnormal vehicle driving. The early warning system comprises a vehicle-mounted early warning device, an information forwarding device and a server, wherein the vehicle-mounted early warning device transmits first vehicle information outwards according to a preset transmission frequency, and the information forwarding device receives and forwards the first vehicle information to the server; the server receives the first vehicle information, determine a first vehicle position, calculates a driving speed of a first vehicle, determines that the first vehicle drives abnormality according to the speed change of the first vehicle and the adjacent vehicles, and generates early warning information which is forwarded to the vehicle-mounted early warning device at the rear of the first vehicle by means of the information forwarding device; and the vehicle-mounted early warning device alerts the personnel in the vehicleaccording to the indication of the early warning information. In this way, whether the vehicle is in an abnormal state can be monitored in real time through the information interaction among the vehicle-mounted early warning device, the information forwarding device and the server in the early warning system, and the personnel in the vehicle can be timely alarmed, thereby being conductive to improving the timeliness of accident early warning.

The invention discloses a rollover support device for a liquid tank truck and a method for controlling elongation of a rack thereof. The rollover support device includes a first rack, a second rack, a rollover monitoring unit, a horizontal movement mechanism, a vertical movement Mechanism, alarm controller and rollover support device controller, the horizontal movement mechanism includes the first motor, the first pawl, the first ratchet, the first gear and the first auxiliary pulley, the vertical movement mechanism includes the second motor, the second ratchet pawl, second ratchet, second gear and second auxiliary pulley. The control method is as follows: when the monitored roll angle is less than the calibrated threshold K, the vehicle runs normally, and the rollover monitoring unit continues to collect data but does not output a control signal; when the monitored roll angle is greater than the calibrated threshold K , the rollover support controller outputs a control signal to control the extension of the first rack and the second rack, and at the same time controls the alarm control unit to give an alarm.

The invention discloses a wind-driven ship that can steer according to the wind direction, comprising a hull and a rectangular block fixedly connected to the upper end surface of the hull, a rectangular hole opening downward is arranged in the rectangular block, and a rectangular hole located on the lower side of the rectangular hole is fixed in the hull. And the rectangular cavity connected with the rectangular hole, the first cavity located on the lower side of the rectangular cavity and partially connected with the rectangular cavity is fixed in the hull. The present invention is a sea-going ship that can convert the wind energy of sea breeze into electric energy , the present invention can utilize wind energy to the greatest extent, the height of the working block can be adjusted through the present invention, so that the fan blade is at the maximum wind speed, and the angle of the working block can be adjusted so that the fan blade is always in the direction perpendicular to the wind direction, so that the fan blade The rotation speed is the largest, and the wind energy can be fully converted into electric energy to provide power for the navigation of the ship. When the wind is too strong, the alarm device of the present invention will send out a prompt sound to remind the crew to pay attention to driving safety.
