Abstract

The utility model provides a remote strain measuring collector which comprises a strain gauge communication interface, a controller, a memory, an short massage (SM) transceiver module and a power supply, wherein the strain gauge communication interface, the memory and the SM transceiver module are electrically connected with the controller respectively, and the strain gauge communication interface, the controller, the memory and the SM transceiver module are electrically connected with the power supply respectively. Because the remote strain measuring collector is provided with the SM transceiver module, the working staff can control the collector by sending short messages through a cell phone or sending Fetion through a computer to collect stain data, and the collected data is also sent to the cell phone or the computer of the working staff through short messages or Fetion. The remote strain measuring collector can measure a plurality of strain points and all strain points of a plurality of bridges, ensures the monitoring quality, improves the efficiency and the precision of data collection and greatly saves human resources without attended monitoring.

Description

Long-range strain measurement collector

Technical field

The utility model relates to the strain monitoring technical field, is specifically related to a kind of long-range strain measurement collector.

Background technology

The strain monitoring technology is widely used in deflection of bridge span, land subsidence, monitorings such as massif moves, as strain monitoring to bridge, present method is that the vibratory string strain transducer is installed in the bridge structure, monitor staff every day is when temperature stabilization, carrying readout instrument climbs up bridge and removes to gather strain data, for bridge with a plurality of cross sections, also need to climb up and climb down by framing scaffold in a short period of time all cross sections, working strength is big, dangerous high, owing to be difficult to measure in the time at same temperature stabilization the strain measurement point in a plurality of cross sections, quality monitoring is difficult to guarantee simultaneously.In addition, next monitoring technique personnel of most cases only need remove bridge every day once, freely arrange At All Other Times.But can not leave bridge construction site.So the construction monitoring of a bridge will a technician be treated several years.Form serious waste of human resource.Some companies have planned to abandon the construction monitoring industry.

Existing strain monitoring system, its strain data harvester is in running order for a long time, and power consumption is big, the failure rate height, and the strain monitoring object is in the field usually the civil power part is not installed, power supply with safeguard all very constantly, had a strong impact on the strain monitoring The Application of Technology; Its strain data harvester and management devices also adopt wired connection usually, bring difficulty for the installation and the use of strain monitoring system.

As publication number is the Chinese utility application Publication Specification of CN1901418A, a kind of soil property side slope distributive fiber optic strain monitoring method and system are wherein disclosed, wherein distribution type fiber-optic links by local computer and internet and remote computer, the on-the-spot local computer of its monitoring promptly needs commercial power supply to work, and local computer is connected for the field monitoring object by the internet with remote computer and also is difficult to realize.

The utility model content

In view of this, in order to address the above problem, the utility model provides a kind of long-range strain measurement collector, can pass through note or Fetion to the collector Long-distance Control, gathers the strain detecting data of strainometer.

The purpose of this utility model is to realize like this, long-range strain measurement collector, it is characterized in that: comprise strainometer communication interface, control device, storer, short message transceiving module and power supply, described strainometer communication interface, storer, short message transceiving module are electrically connected with control device respectively, and described strainometer communication interface, control device, storer, short message transceiving module are electrically connected with power supply respectively.

Further, described short message transceiving module is a gsm module;

Further, described control device is a single-chip microcomputer;

Further, described power supply is a battery.

With respect to prior art, the utlity model has following advantage: long-range strain measurement collector is provided with short message transceiving module, the staff can send Fetion by sending short message by mobile phone or computing machine collector is controlled, carry out the strain data collection, the data that collect also send to staff's mobile phone or computing machine by note or Fetion; Can measure a plurality of points simultaneously, in addition all strain points of a plurality of bridges, guarantee monitoring quality, improve data acquisition efficiency and accuracy rate, the post monitoring that also need not to send someone is on-the-spot, can greatly save human resources.

Other advantages of the present utility model, target, to set forth in the following description to a certain extent with feature, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can be passed through following instructions, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.
