The invention relates generally to a method and system for monitoring traffic events at a predetermined location, using a temporary video camera set up to record traffic movements through an intersection or other location along a road. The method preferably comprises taking a video recording of the location, and then sending the recording to a foreign country where the recording can be reviewed manually at a reduced cost. To facilitate an accurate and consistent review of the recording, the invention preferably uses “event lines” that can be superimposed on the video monitor, wherein the event lines help determine when a vehicle has passed through an intersection, i.e., when a recordable traffic event occurs. The system also preferably uses a computer-operated program adapted to assist the operator in reviewing, verifying and summarizing the recorded information, wherein a particular key or keys can be pressed depending on the type of event to be indicated. The system is also able to identify the exact frame number of a recordable event that corresponds to an exact moment in real time, i.e., when the event actually occurred. A tripod-like apparatus for temporarily setting up a video camera in locations where no existing pole or structure is available, as well as a tamper-proof housing in which the video recording device can be temporarily mounted, can also be provided.

The invention relates to a motor for oil field drilling, and the motor comprises a pedestal and a motor main body. One side of the motor main body is provided with a wiring box, and the top of the motor main body is provided with an explosion-proof fan, and the wiring box and the explosion-proof fan are connected to the motor main body through explosion-proof pipes. The motor main body comprises a main shaft, an armature, a stator and a brush carrier. The brush carrier is disposed at one side of the armature, and the motor main body at the top of the brush carrier is provided with a cover plate. The motor main body at one side is provided with an end cover and a pressure plate, and two ends of the main shaft are respectively provided with a first rolling bearing assembly and a second rolling bearing assembly. The first rolling bearing assembly is sealed through a labyrinth bearing sealing structure. The interior of the motor main body also comprises a heater device and a bearing temperature measuring device. After the above structure is employed, the motor is strong in overload capability, is high in reliability, is easy to maintain, and maintains the same size as the size of a motor of the same type in a foreign country. Moreover, the performance index reaches the foreign level, and the motor can completely be used for replacing the motors of the same type in the foreign country, and is worthy of popularization in the whole industry.
