As shown in Fig. 2 for automation deviational survey controller of the present invention gathers deviational survey in the automation deviational survey collectorIts course of work during data：
First, during system starts, controller detects whether the deviational survey sensor of collector is being surveyed by door status switchAt inclined tube mouthful.If not in the mouth of pipe, controller motor draws the deviational survey sensor motion of collector, until controller detectionTo the stopping signal that door status switch sends, controller stopping motor movement.During traction, pressure detecting system, controlThe pulling force born on device real-time detection draught line, when threshold value of the pulling force more than setting, controller stops motor and operates upwards, andOne segment distance of decentralization is attempted, pull-up is then proceeded to.
Further, collector deviational survey sensor has been positioned at the deviational survey mouth of pipe.Controller and collector are built by wireless moduleVertical communication, carries out parameter configuration, and (if not having data in collector, controller can be skipped automatically to read the data in collectorRead operation), upload to data cloud platform.After digital independent terminates, controller generates the working time according to the parameter of configurationTable, reset distance-measuring equipment, and start epicycle collection.
Further, operating schedule is made up of stand-by time, collector working time, controller working time, such as Fig. 3 institutesShow.Stand-by time, refers to the time interval that first round collection terminates to start to the second wheel collector, in the interval, collectionDevice and controller are in holding state.The collector working time, refer to collector and stop at measurement point position postponing, collection is surveyedThe working time of amount point heeling condition.The controller working time, refer to controller controlled motor and transferred to from current collection pointThe working time of next collection point.
Further, wait stand-by time to terminate, and complete first data acquisition of measurement point, i.e. collector working time1 exhausts, now the controller working time arrive, controller start motor, collector is transferred into next measurement point.Until controlThe device working time 1 exhausts.Collector starts deviational survey sensor, completes to second data acquisition of measurement point, by that analogy, directlyThe data acquisition to last measurement point is completed to collector.
Further, the data acquisition when completion to last measurement point, controller motor, by the deviational survey of collectorSensor is drawn to the deviational survey mouth of pipe, and configuration collector, reading collector data upload the data to data, services cloud platform, andStart next round collection.
Further, during being transferred in the deviational survey sensor of collector, if be stuck, it is impossible to reach the survey specifiedAmount point, controller can be drawn to the deviational survey mouth of pipe collector, complete epicycle collection.
As shown in figure 4, automating the course of work of deviational survey collector described in inclination measurement system of the present invention：
First, during system starts, the peripheral hardware to using is initialized, and closes the power supply of deviation survey equipment, to dropLow system power dissipation.Collector systems are developed based on message mechanism, and at the beginning without message in message queue, system is in lowPower consumption mode.When there is external message event to trigger, system wakes up from low-power consumption mode, the message in treatment message queue, placeLow-power consumption mode is gone successively to after having managed.
Further, external message event includes, deviational survey data acquisition message that timer sends, deviational survey data calculation disappearBreath, deviation survey equipment data answering message, wireless module receives message.
Further, system sends deviational survey sensor acquisition, when receiving sensing when deviational survey data acquisition message is processedDuring the tilt data of device response, trigger deviation survey equipment data answering message, system in the processing procedure of the message, by deviational survey valueParsed from data protocol bag, and preserved.
Further, when reaching the sensor resolving time, deviational survey data calculation message, treatment of the system in the message are triggeredDuring, complete to be worth smoothing processing to deviational survey, and preserve.
Further, when wireless module receives controller data, triggering wireless module receives message.System is according to the number for receivingAccording to data content, corresponding treatment is done to message.
The preferred embodiments of the present invention are the foregoing is only, is not intended to limit the invention, for the skill of this areaFor art personnel, the present invention can have various modifications and variations.It is all within the spirit and principles in the present invention, made any repairChange, equivalent, improvement etc., should be included within the scope of the present invention.
