Multi-point remote monitoring system for settlement

Abstract

The invention belongs to the field of building settlement detection and relates to a multi-point remote monitoring system for settlement. The system comprises monitoring base point equipment, detecting point equipment, a communication pipe, a programmable logic controller, a power supply, general packet wireless service equipment and a data logging alarming device, wherein the power supply supplies power to the monitoring base point equipment, the detecting point equipment, the programmable logic controller, the general packet wireless service equipment and the data logging alarming device through cables; the monitoring base point equipment and the detecting point equipment are connected with each other through the communication pipe; monitoring data of the monitoring base point equipment and the detecting point equipment is transmitted to the programmable logic controller; the settlement amount of a monitoring point is analyzed and figured out; and the data is remotely transmitted through the general packet wireless service equipment. According to the invention, convenience for increasing and reducing the number of the monitoring points can be provided, the effectiveness and the intelligence of monitoring means are improved, secondary hazards caused by valve chamber settlements with different degrees can be found in time through real-time monitoring, safety accidents are prevented, and simple structural composition and simplicity in construction are achieved.

Description

technical field [0001] The invention belongs to the field of remote transmission system for real-time monitoring of building settlement, and in particular relates to a multi-point remote intelligent real-time monitoring system for settlement applied to valve chambers of long-distance oil and gas pipelines. Background technique [0002] The PetroChina Shaanxi-Beijing Line crosses the Loess Plateau in Shaanxi and Shanxi, and most of the natural gas valve chamber stations are located in relatively remote areas. The loess on the Loess Plateau has strong collapsibility, and the bearing capacity of the foundation itself is relatively weak. After heavy rain, the foundation is prone to large settlements, resulting in various degrees of settlement in the valve room station, and the on-site maintenance engineers are inconvenient to reach The subsidence problem was found in time in the valve room. Summarizing the settlement of the valve chambers of the first, second, and third lines i...

Problems solved by technology

The method is to drill a hole at the observation point, bury a fixed rod with a casing, insert the lower end of the rod into the hard layer, and lead out the ground (or seabed surface) at the upper end, set the settlement plate and the measuring device on the fixed rod, and set the settlement plate and The vertical displacement of the fixed rod is the settlement at the settlement plate. The vertical displacement can be observed by the measuring device. This method has relatively high measurement accuracy, but the equipment price is generally high, and it is not easy to monitor in real time.

[0007] The above-mentioned monitoring methods have been developed relatively maturely, but the monitoring methods are basically concentrated on the level of routine monitoring and manual data collection. The monitoring range is small, the workload is heavy, the efficiency is low, and the investment is high. There are disadvantages of missed detection, let alone real-time monitoring. Monitoring and data analysis and processing

Most of the current data are provided for the seismic design of buildings, and cannot be used for long-term monitoring and control in engineering practice.
