[0002] For large-scale transportation of power equipment, the National Development and Reform Commission issued DL / T 1071-2007 "Specification for Large-scale Electric Power Transportation" in July 2007, and it began to be implemented on December 1 of that year. , pre-preparation, organization and implementation, and project summary have made procedural regulations on the transportation of large-scale electric power; large-scale electric equipment is the basic component of the smart grid, with the characteristics of ultra-long, ultra-wide, and over-weight, and its own value is high, The production cycle is long, once a safety and quality accident occurs in the transportation link, it will cause serious direct losses and inestimable indirect losses; the infrastructure construction of the smart grid is realized by the specific process of purchasing, transporting, installing, and operating power equipment one by one Yes, the transportation of power equipment is a test of extreme transportation conditions. The transportation shock will not only cause damage to the transformer, but more seriously will greatly endanger the transportation safety. Therefore, it is necessary to monitor the shock, vibration and acceleration during transportation in real time Monitoring to ensure transportation safety does not involve the use of technical means to control the description of the transportation quality of electric equipment. In the actual operation of large-scale electric power transportation, there is no research and application on the online management and control information system of electric equipment transportation quality.

[0003] At present, some of the most commonly used transportation monitoring equipment in China are mechanical equipment, mainly mechanical impact recorder, its internal structure is equivalent to a camera, and its working principle is to put the recording paper tape into the upper paper bag roll Insert the beginning end of the paper tape into the lower paper bag reel, and fix 3 recording pens on the metal beam on the paper bag. They are used to record the impact force on the x, y, and z axes respectively. There are grids on the paper tape, read The number of grids can reflect the degree of impact. There are times on both sides to record the time of impact. There is also a meter-type recorder, which cannot record time and can only display the maximum through the meter. Shock level, obviously, these devices all have some flaws:

[0004] 1. Due to different transportation methods, sometimes the recording paper may be used up due to the vibration amplitude is too large, the time is too long, etc., and the transportation status of the equipment cannot be fully recorded, resulting in data loss and a narrow measurement range;

[0005] 2. The structure is complex and not easy to carry, which is not conducive to long-distance transportation of equipment;

[0006] 3. The recording paper may be jammed due to moisture during transportation, resulting in data loss

[0008] 1. Due to the long transportation time during transportation, the storage space is insufficient, and the transportation status of the equipment cannot be fully recorded, resulting in data loss;

[0009] 2. During the long-distance transportation, the damage to the equipment, power failure, data loss and other phenomena are unpredictable, and the data is lost or incomplete when opened at the destination;

[0010] 3. The external protection level is low, dust, fog, rain and other factors may cause the equipment to fail to work normally, the records are wrong or the equipment is damaged
