The invention relates to a pile engine, belonging to the technical field of pile engine structure. The pile engine is characterized in that the pile engine is composed of a pile pole (1), a hollow hammer (2), and an anvil pin (3), wherein the hollow hammer (2) coats on the periphery of the pile pole (1) and can slide vertically, the pile pole (1) at the lower part of the hollow hammer (2) is provided with through holes (4) arranged at an interval for passing through the anvil pin (3), and the anvil pin (3) passes through the through holes (4) and are fixed on the pile pole (1). The pile engineof the invention utilizes the pile pole as a central shaft, can cause the hollow hammer accurately strike on the anvil pin, can quickly tamp the pile pole into the soil without mechanical force, hassimple structure, rapid and convenient assembly and disassembly, and flexible and safe use, and is suitable for any abominable working environment.

The invention provides a discharging test device for a full online storage battery, mainly comprising a DC-DC host operating power supply, a control unit, a safeguard circuit, an automatic limited current charging and equipotential connection safety control circuit, a constant current discharge load intelligent control circuit and a discharge load circuit, wherein the safeguard circuit and the automatic limited current charging and equipotential connection safety control circuit are connected in parallel; and the constant current discharge load intelligent control circuit and the discharge load circuit are connected in series. The discharging test device for the full online storage battery of the invention has a safe energy saving discharge function of the full online batteries on load ofa communication device and a function of intelligently controlling and regulating discharge load current through an online constant current discharge load, is suitable for constant current discharge test of the online storage battery for the current in different communication device loads in the existing network and automatically auxiliary regulation of operating current in the discharge load, and has manual, automatic and remote control functions. By using the discharging test device, the full online constant current discharge capacity test for the storage battery can be achieved.

The invention discloses a shoring stabilization device which can be used through combination between a shoring post base and a warning ring. The shoring post base is of an integral structure formed by a non-metallic material, an internal flat metal base plate and main plate ribs through processes such as the injection molding process, the casting process and the pouring process, and can well combine strength, toughness, corrosion prevention, light weight and other features. The phenomenon that a metal structure shoring post base is heavy and not attractive in the transport and installation processes can be avoided; installation efficiency and safety of the shoring post base are improved, the phenomena that other devices are corroded due to long-term use of metal materials, and safety of the corroded devices is poor can be avoided, labor intensity is greatly reduced, and installation efficiency is improved; in addition, due to the fact that the shoring post base can be freely connected with the warning ring, safety and attraction are improved. The shoring stabilization device is convenient to combine, rapid, attractive and reliable, flexible to use and higher in standardization; the shoring post base and the warning ring of the shoring stabilization device can be respectively formed through machining at one time, and production efficiency is high.

The invention discloses a 360-degree panoramic stitching method. The method comprises four steps: step 1, setting the visual field of an outputting panoramic aerial view; step 2, turning on a panoramic four-way camera, and acquiring each frame of image and image pixels at the same time; step 3, determining a mapping region and a fusing region; and step 4, calculating a map between the original image and the top view. The 360-degree panoramic stitching method is used for 360-degree panoramic stitching.
