Background

The steam turbine is used as a core component of a power plant generating set, the manufacturing cost is high, and the maintenance cost is high, so that safe and reliable operation must be ensured after the steam turbine is overhauled. And in the maintenance work of power plant, the steam turbine inner casing disintegrates, the rotor lifts by crane, the work such as lid jar repacking, as the important link in the work of a standard maintenance, if carelessly fall into the jar with multiplexer utensil in the operation and do not fish out, then can arouse the inside damage of steam turbine when the steam turbine starts, cause the incident, consequently need to keep alert constantly during the maintenance work, in cautious against multiplexer utensil falls into the jar.

In the existing maintenance work, when a worker enters the working site of the inner cylinder, the worker must transfer the coveralls and the nailless shoes, and all articles on the body must be taken out and cannot be brought into the working site. The range of the overhaul region is defined by a fence, an entrance and an exit are arranged, a special person is arranged to manage the entrance and the exit, and the person must register names, departments and entering and exiting time on site. Each tool entering the site must be recorded in a bill, and the type and the entering and exiting time of the tool are recorded in detail. After the cylinder is buckled, all tools must be checked to ensure that the tools are not left in the cylinder. If the number of the tools is not correct, the falling is required to be searched, and the outer cylinder can be buckled at the rear part.

The disadvantages are as follows: in the whole cylinder maintenance process, the management of the in-and-out maintenance area must be registered in a bill, so that the method is the link with the lowest efficiency. When workers enter and exit the overhaul area every time, the workers must sign respective names, departments, tool names, entry and exit time and other information on the account book, and time cost is greatly increased. If a large number of people rush in the morning, congestion at the entrance and exit can also occur. In addition, manual checking is needed for the in-and-out arrangement and checking of the tools, so that special management tool checking books must be arranged at the entrances and exits, the manual checking is subject to the manual checking speed, the handwriting definition of the tool checking books and other factors, and the efficiency is low. If the tool is left out and found out untimely, serious consequences can be caused.
