The invention discloses a railway special line vehicle safety monitoring device and method. In the device and method, a scanning camera, a light source, a laser sensor, a weighing and metering device,a vehicle number recognition device and a server are arranged. The server is respectively connected with the scanning camera, the laser sensor, the weighing and metering device, and the vehicle number recognition device so that it can record weight information, vehicle number information and top load status three-dimensional information of railway vehicles and vehicle stopping time information ofspecial line at the same time, and complete automatic collection and processing of status information of loading and unloading vehicles of special line through the server, thereby avoiding influenceof inconsistent time on the integration of different information, realizing effective integration of railway vehicle information, improving matching accuracy of a variety of information of the vehicles, and improving safety monitoring efficiency of railway freight.

The invention discloses a mass spectrometer based RH dynamic decarbonization method and device for real-time calculation of carbon content when in vacuum oxygen decarburization, and realization of automatic gun lifting and stopping of oxygen blowing when the carbon content of molten steel reaches target carbon content. The decarbonization method comprises the following steps: when a heat is started, the weight, initial component and target component data of the molten steel is collected, in the smelting process, waste gas real-time flow rate acquired by a waste gas flow meter and waste gas real-time component acquired by a mass spectrometer are collected; according to relevant information of the molten steel, and relevant data of the collection and analysis time delay of the waste gas and gun lifting and blowing-stop time delay of a top gun, the carbon content of the molten steel is calculated in real time, and when the current carbon content is smaller than or equal to the target carbon content, a PLC (programmable logic controller) is notified to stop oxygen blowing and lift the gun. The mass spectrometer based RH dynamic decarbonization device can realize the automatic control of mass spectrometer based RH dynamic decarbonization, is precise in control of process and high in production precision, can shorten the smelting cycle, and reduces the cost.

The invention relates to an automatic automobile warning sign placement trolley. A warning sign and the trolley are folded into a shutter ramp and placed at the bottom of an automobile. When the automatic automobile warning sign placement trolley is used, the shutter ramp is open under remote control, and the advancing direction of the trolley can be adjusted under remote control. If lane lines are continuous, a photoswitch, a logic circuit, a direction adjustment needle and a gear rack are used for adjusting on, off and steering angles of a steering gear according to reflection difference of a road surface and the lane lines so as to control the advancing direction of the trolley. A cam shifting gear is mounted on a trolley shaft to control warning sign open and trolley stopping time.

The invention discloses a wound protecting composition with bleeding-stopping and anti-bacterial functions and a preparation method of the wound protecting composition. The wound protecting composition comprises the following steps: (1) preparing an organic high molecular mixed solution; (2) adding one or two of chitosan and chitin into acetic acid, ethanol and water so as to prepare a bleeding-stopping and anti-bacterial material solution; (3) carrying out multi-spray-head electrostatic spinning so as to prepare a composite fiber material; and (4) drying the composite fiber material, removing residual solvents, and carrying out hot-press shaping, so as to prepare the wound protecting composition with the bleeding-stopping and anti-bacterial functions. The wound protecting composition disclosed by the invention has good bleeding-stopping and anti-bacterial effects, can be used for cleaning wounds and is good in biocompatibility; the water absorption rate is obviously increased, the bleeding-stopping time is greatly shortened, and the wounds are further protected.

The present invention promotes the use of contents distribution by multicast, and enables users to stop viewing without needing special processing in a terminal, and to restart viewing in the same terminal as that at stop time or a different terminal, thus increasing users' usability and use opportunities. In a distribution system including a service server, a multicast distribution server, and a unicast distribution server, the service server, in a first access from a PC, selects the multicast distribution server as a distribution server, and selects the unicast distribution server as a distribution server after stopping.

The present invention discloses a fan protection apparatus and related method thereof. The fan protection apparatus has a control circuit and a counter. According to the fan protection method, the user can set the acceptable restart number and the special time for auto restart. The fan protection apparatus and method can force to stop the fan when the fan encounters an abnormal situation. When the stop time has passed, the fan is automatically restarted. The present invention counts the number of restarts. If the number of restarts equals the set number and the abnormal situation also cannot be eliminated, the present invention cuts off power to the fan
