3) single-chip microcomputer master routine
Single-chip microcomputer need receive the displacement signal of processing horizontal electric rotating machine and angular displacement motor as the core of whole measuring instrument, controls each motor operation; The control laser range sensor detects; Also want the received communication instruction, send and detect data etc.Its software main flow block diagram is seen Fig. 7.Software can be write by the common software personnel and form.
During single-chip microcomputer work, at first get into initialization, wait for then receiving parameter and order are set.The height that parameter is mainly the input support bar is set, when parameter is set when receiving; Directly do not get into the order operation as parameter is set after the start, the parameter that parameter adopts the front to be provided with then is set.During first the operation, it is 1m that parameter is set.
When action command, take out parameter is set, according to the different number of turns of different support bar high computational, and calculate the number of whenever punctuating.This is because highly not simultaneously, the laser ranging of same angle, and the radius at tested position is just different on the ground, and detecting the number of turns will change.In like manner, the girth of every circle is changing, and every circle detects to count and also will calculate variation.
After every some detection, recording detection data.Control motor again and forward next some detection to, finish, send data up to every whole detection of every circle.Then, wait for next work order.
4) physical construction
(1) spud pile
Spud pile is mainly used in the measuring center fixed-site, ensures data measured repeatability.Spud pile at ordinary times not the time spent stay undergroundly, cover above and protect, remove protective seam during use and can use.
Because it is underground that spud pile forever is embedded in for a long time, must have antirust ability to the spud pile tube material; The spud pile pipe also need support the measuring appliance operation of nearly 15kg weight, and material will have certain length and diameter, can not be too heavy, cause difficult.Therefore spud pile employing diameter 89mm, interior wall thickness 5mm, length are the hot dip galvanizing pipe processing of 500mm, can satisfy the requirement to the spud pile material basically.
Spud pile has the connector that connects support bar, needs to adopt rush-resisting material processing equally, selects to use No. 304 stainless steel materials to process.Connector embeds spud pile pipe top and is welded.
For spud pile is buried underground easily, fined away in spud pile pipe bottom, and design one with the supporting attachment cap 1-5 of connector screw thread.As long as will connect the head cap rotation set when burying underground on connector, hammering cap head gets final product.
Another function of attachment cap be spud pile be embedded in underground after, put attachment cap and can prevent that foreign material, mud, fine sand etc. from clinging the connector screw, cause the support bar difficulty be installed.
In addition, when spud pile is buried underground, keep perpendicular to the ground, in the connector screw, a spirit bubble 1-1 (with organic glass 1-3 protection) has been installed, it is perpendicular to the ground as far as possible when burying underground to estimate the control spud pile.
(2) support bar
Support bar is used for measuring head and spud pile are coupled together, and guarantees certain measuring height.
When preventing to measure, measuring head is owing to flowing of air caused slight swing, thereby influence measuring accuracy, and the while again can not be too heavy.Support bar recommends to select for use diameter 42mm, 304 stainless-steel tubes of wall thickness 3.5mm.
Consider convenient transportation, recommend the support bar that 2m is long to be divided into 3 joints.The 1m1 joint, the 0.5m2 joint.Precision when guaranteeing that two bars connect adopts 1.5 fine thread to connect between two bars, guarantee to connect fine and close.
