Controller area network (CAN) bus-based settlement deformation monitoring system

Abstract

The invention discloses a controller area network (CAN) bus-based settlement deformation monitoring system which comprises a power module, a remote transmission module, at least one monitoring subsystem, and a remote monitoring server and a monitoring mobile phone that are used for carrying out data processing, wherein the monitoring subsystem comprises a data acquisition unit and a plurality of inductive transducers used for acquiring the foundation settlement deformation; the plurality of inductive transducers are arranged on the foundation and are respectively connected with the corresponding data acquisition unit so as to realize data exchange; every two adjacent data acquisition units are connected with each other in series by a CAN bus; the remote transmission module is connected with the CAN bus, so that data transmission can be realized; and the remote transmission module is also respectively connected with the monitoring mobile phone and the remote monitoring server by a wireless network, so that data exchange can be realized. The CAN bus-based settlement deformation monitoring system can be used for monitoring the foundation settlement deformation in real time effectively and rapidly, and is high in reliability, thus not only reducing the work load of operators, but also being long in communication distance and realizing real-time data transmission and data resource sharing; and the monitoring system integrates multiple monitoring ways.

Description

technical field [0001] The invention relates to a CAN bus-based settlement deformation monitoring system, which belongs to the technical field of monitoring and control. Background technique [0002] At present, during the operation of the subway, due to factors such as climate, oxidation, corrosion or aging, and long-term damage under the action of dead load or live load, the foundation of the subway elevated will suffer from settlement and deformation, which not only affects safe driving, It will also shorten the service life of the subway elevated, so it is necessary to establish a settlement deformation monitoring system that integrates foundation settlement deformation analysis, computer communication and network, modern sensor detection, and monitoring technology on the basis of the existing technical level. To monitor and evaluate the operation status of the subway elevated, to provide a basis for maintenance management. [0003] In order to implement health and safe...

Problems solved by technology

In addition to the most traditional manual data measurement, recording and processing, the monitoring methods adopted by the existing monitoring system mainly include the monitoring method of establishing a connection using the Rs485 bus. The working process is: the sensor is connected to the acquisition instrument through a cable, The acquisition instrument is connected to the control terminal using the on-site RS485 bus, and the control terminal is connected to the photoelectric converter to access the remote optical cable network, and then establishes a remote connection with the monitoring center computer through the photoelectric converter of the monitoring center to realize the monitoring of foundation settlement deformation. The communication speed is slow, the equipment cost is high, the maintenance is difficult, the monitoring center is relatively fixed, and it is difficult to build a large-scale monitoring network

It requires a lot of manpower and material resources, and it is also very difficult in maintenance and management. It is also very unfavorable for statistical analysis and experience exchange of monitoring conditions.
