With the development of business and information technology, the existing inspection system of pipeline enterprises has become more and more prominent in mobile navigation and office. In particular, there are many drawbacks in the way of traditional relying on personnel to arrive by road . To this end, Sinopec sales in South China Branch and the relevant units to develop a navigation based on mobile navigation hidden point inspection intelligent management system.
1 long-distance pipeline inspection management technology development process
Long-distance pipeline inspection management technology generally experienced five stages of development, as shown in Figure 1.

Figure 1 long-distance pipeline inspection management technology development process
The new inspection and management technology, using GPS, base stations and IP hybrid positioning mode, to achieve the construction point, station number, inspectors and within the city public resources POI retrieval and positioning, based on Android system to establish a mobile end of the pipeline hidden point intelligent Inspection navigation system, call the map SDK interface, with the pipeline, construction points, stations and other professional data, the pipeline routing on the map, station, valve room display and operation functions, for map access. With the help of navigation system, strange people in the pipeline site environment without the relevant staff and without network conditions, inspectors can still set the destination by default, the default search for the nearest path to determine the real-time traffic, voice broadcast and other functions to achieve the path planning and GPS Navigate, arriving at the checkpoint promptly and efficiently. At the same time, but also with the pipeline inspection system integration, so that the oil management department outsiders can use event reporting capabilities, the first time the construction site photo upload, update the relevant data simultaneously and truly intelligent mobile office.
2 research content and key technologies
2.1 establish an intelligent management system
The system management system aims at pipeline safety and intelligence. Based on the intelligent identification and evaluation of the risk factors in the pipeline operation, the Bank has formulated corresponding risk control strategies to control the safety level of pipeline operations to a reasonable extent and reach the intellectual risk Pre-control, the purpose of accident control.
2.2 to enhance the standard management tools
In accordance with the wisdom pipeline management database specification, the hidden trouble point inspection management business standardization, such as: the incident classification and management; standardization of the hidden point inspection business content, so that the existing inspection management system can be transmitted without loss and Realize the data sharing; Through the integrated mobile navigation technology, the technology of things, to achieve standardized and real-time transmission of information; the formation of PDCA closed-loop management process model, so that the hidden pipe point inspection intelligent management more scientific and reasonable.
2.3 to achieve data security management
Encrypt the key data such as offline map data, basic data of pipelines and personnel usage rights, and limit the rights and other technical means, and prevent data leakage and outflow from the management system and management system. At the same time, the use of quad-channel data indexing technology to effectively manage the 4D data and hidden data points, greatly improving the mobile terminal's display, zoom, refresh rate.
2.4 comprehensive use of advanced technology
Based on the positioning technology such as BeiDou positioning, GPS system and RFID electronic tag, it realizes the real-time display of location information, patrol line information and event information by using network data transmission means such as GPRS, 3G, 4G and so on. On the move, to help managers.
3 system architecture and main functions
3.1 system architecture
As shown in FIG. 2, the system integrates with the pipeline inspection system through the server to achieve user rights authentication, data synchronization, data sharing, data encryption, and automatic software update.

A limiter for a Tower Crane is a safety device that is installed to prevent the crane from operating beyond its maximum load capacity or from moving beyond its designated working area. It typically consists of sensors, control systems, and alarms to ensure safe operation.
The load limiter is designed to monitor the load being lifted by the crane and automatically stop the crane's movement if the load exceeds the specified limit. It helps prevent overloading, which can lead to structural failure or accidents.
The radius limiter is used to restrict the crane's movement within a specific working area. It ensures that the crane does not extend beyond its designated radius, preventing it from colliding with nearby structures or obstacles.
Both types of limiters are essential safety features in tower cranes to protect workers, equipment, and the surrounding environment. They help ensure that the tower crane operates within its safe working limits and minimize the risk of accidents or damage.
