Technical Field

The application relates to the technical field of automatic acquisition of vibrating wire sensors, in particular to an automatic acquisition device and system of a vibrating wire sensor.

Background

Modern construction is informatization construction, various rock and soil parameters and the like need to be measured in the construction process, and the measurement and calculation results provide data support for field safety risk management and control, but the traditional manual monitoring means has high cost, low efficiency and poor consistency and cannot meet the requirements of the new era; in the aspect of modern city construction, along with the aggravation of urbanization process, the scale of the urban construction is larger and larger, the construction of large underground infrastructures such as subways and municipal buildings is greatly increased, and secondary disasters caused by soil disturbance, water and soil loss and the like due to underground space construction are promoted year by year; with the increasing amount of basic facilities and buildings such as urban overpasses, rail transit, tunnel bridges and the like, a large number of buildings (structures) lack effective monitoring throughout the year, and special systemic risks of large cities are accumulated; the method is influenced by various natural factors (such as earthquakes, typhoons, rainfall and the like) and human factors, frequent geological disasters such as landslide, land settlement and the like occur, and accidents such as reservoir leakage, mine collapse and the like are accompanied to cause casualties and property loss, so that the social attention to the events is high, and the accommodation degree is low.

In order to solve the problems, various monitoring technologies are used at present, and the monitoring contents comprise rock-soil displacement, axial force, stress, settlement, deep soil displacement and layered settlement, soil pressure, anchor rod stress, osmotic pressure, water level and the like.

By adopting a high-precision photoelectric measurement system, a high-precision photoelectric measurement device and GNSS monitoring equipment, all requirements of ground monitoring can be well met in the technical aspect; however, for means for monitoring internal elements of rock mass, wall body or soil body, such as measuring methods of soil pressure, stress, water level, osmotic pressure and the like, the traditional vibrating wire sensor is mainly used, and parameters are still obtained by adopting a manual reading method, so that an automatic acquisition mode is required to improve the working efficiency; the latest fiber grating sensor can be used for measuring the internal elements of the rock-soil body, but has the problems of difficult installation, high use cost, difficult maintenance and the like.

In view of the increasing demand for monitoring information and the increasing labor costs, much effort has been devoted to developing automated monitoring; in the current stage, for monitoring key point information, various scattered intelligent instruments, equipment and sensors are arranged in a monitoring area, and measurement of a plurality of parameters is completed by adopting various means.

The pain points of the monitoring application of the existing vibrating wire sensor are summarized as follows:

(1) the vibrating wire sensors are distributed dispersedly, the field environment of the installation position is severe, personnel are not easy to reach, the detection is time-consuming and labor-consuming, the requirement on the personnel is high, and the monitoring data management is troublesome;

(2) in order to reduce the operation risk of monitoring personnel, a sensor cable is often required to be laid in an operation convenient area during manual detection, so that the cable laying workload, the cost and the field cable protection are difficult problems which cannot be avoided;

(3) the existing method of the developed automatic acquisition system of the vibrating wire sensors can be called as centralized automatic monitoring, and is characterized in that all vibrating wire sensor signal cables are added to be long enough and then are led into a centralized wiring cabinet along a rock (wall) body and the ground; a vibrating wire signal acquisition host, an interface expansion unit, a communication unit, a power supply unit, a lightning protection unit and the like are arranged in the cabinet; according to the automatic scheme, the cable laying distance is long, the construction difficulty is high, the line protection is difficult, the system is fragile (caused by complete centralization), the automation cost is high, and a monitoring unit feels that the system is "afraid of using" (difficult to unfold), "not using" (the field line is often damaged by construction influence), and "using" is impossible "(the cost of cable laying maintenance is possibly more expensive than that of automatic equipment).

(4) Another disadvantage of the centralized automatic monitoring system is that the adaptability to the accessed vibrating wire sensors is not good for sensors of recommended manufacturers of compatible systems, but the compatibility to other non-recommended vibrating wire sensors is not good.

(5) The position of the vibrating wire sensor equipment cannot be sensed by the centralized automatic monitoring system, so that GIS management cannot be realized;

in the face of the problems, how to realize the automatic acquisition of the vibrating wire sensor through a scientific and technological means which is convenient, practical and high in cost performance and acquire real-time and accurate monitoring data is a problem to be solved.
