The invention discloses a dynamic monitoring and management system for mine safety, which relates to the technical field of mine safety and includes a ground monitoring module, a wireless transmission module and an underground monitoring module. The ground monitoring module includes a central processing unit, a man-machine operation module, and a data storage module , a liquid crystal display, a ground alarm and an emergency rescue module, the central processing unit is electrically connected to the man-machine operation module, the data storage module, the liquid crystal display, the ground alarm and the emergency rescue module. The invention not only monitors various environmental data information inside the coal mine roadway in real time, so that the ground safety production personnel can know the specific situation inside the coal mine roadway in time, but also performs timely alarm according to the environmental change information inside the coal mine roadway, reminding the coal miners to evacuate as soon as possible or After an emergency occurs, a rescue signal is sent to the rescue center in time, so that the rescue center can arrange rescue as soon as possible and improve rescue efficiency. It is very suitable for dynamic monitoring and management of mine safety.

The invention relates to a natural circulation split shell-and-tube waste heat boiler with optimized flow field layout, which includes a drum and a steam drum. The drum is divided into a flue gas inlet, a heat exchange chamber and a flue gas outlet; The water pipe is connected to the water collection pipe; the heat exchange chamber is arranged with a heat exchange tube bundle; the heat exchange chamber is divided into several heat exchange units by arranging vertical support baffles, and each heat exchange unit is connected to the steam drum through a riser pipe. The upper ends of the ascending tubes extend into the steam drum and are always above the liquid level in the steam drum; there are tube holes on the support baffle for the passage of the heat exchange tube bundle, and there are holes between the tube holes on the lower part of the support baffle. The baffle hole; the steam drum is provided with a steam drum water supply port and several steam outlets; the steam drum is connected with the water collection pipe through the downpipe. The invention can solve the problem that the vapor-liquid two-phase flow in the middle and lower drum of the split-tube shell type waste heat boiler is disordered and the vapor-liquid two-phase flow in the rising pipe is stagnant or even reversed.

The invention provides a blowout gas flow velocity measurement method based on image feature recognition, comprising the following steps: Step 1. Collect a large number of on-site blowout gas high-speed images; Step 2. Perform feature recognition processing on the high-speed images in Step 1; Step 3. Select Obtain two adjacent frames of images with relatively excellent feature points; Step 4. Perform image processing on the two frames of images in Step 3; Step 5. Calculate the blowout gas flow rate through displacement and time. By adopting the method of the invention, the blowout gas flow rate can be obtained under the condition of ensuring the safety of field operators, and economic losses and casualties can be reduced.

The present invention relates to vehicle safety technology, in particular to a vehicle with an escape system. The present invention is achieved through the following technical solutions: a vehicle with an escape system, comprising a body, a closure member for closing the side wall of the body, and the closure member is rotatably connected to the body; the vehicle also has a vehicle body capable of enabling The closure is relaxed from the body or a control assembly that maintains a closed state of the body sidewall. The present invention facilitates the timely activation of the escape system when an accident occurs, and facilitates the evacuation of passengers in the vehicle in a relatively short period of time.

A multifunctional emergency lamp control system comprises an upper computer and a plurality of emergency lamps. Each emergency lamp comprises a wireless communication module, a light operated module, a fire alarm module, a second pyroelectric infrared sensor module and a first pyroelectric infrared sensor module. The control method of the multifunctional emergency lamp control system includes steps of firstly, acquiring level signals in real time and sending the level signals to the upper computer by a lower computer, continuously acquiring the level signals and sending the level signals to the upper computer by the lower computer if finding no abnormal level signals, and otherwise, executing the next step; secondly, sending numbers of the emergency lamps which send out the abnormal level signals and types of the abnormal level signals to the upper computer by the lower computer, and simultaneously, enabling the light operated module, the fire alarm module and the second pyroelectric infrared sensor module to make response under control of the lower computer; and thirdly, displaying relevant information through the upper computer. The emergency lamp control system has multiple functions of power-off illumination, burglary prevention and fire alarm, and has the advantages of high practicability and the like.
