Need by CPU, acceleration signal only to be processed.Easy to use, greatly save
The man power and material consumed owing to repeatedly laying wired data acquisition equipment in test,
Fig. 1 is the structural representation of one embodiment of control system of dynamic compaction machinery automatic job of the present invention.
As it is shown in figure 1, this system includes:
Pressure transducer 101, is arranged on hoist motor, for promoting hammer ram at hoist motor
During, Real-time Collection hoist motor pressure, and it is transferred to controller.
Elevator encoder 102, is arranged on hoist motor, for by the real-time reading of elevator encoder
Number is transferred to controller.
It is for instance possible to use absolute value encoder is in real time by the position of hoist motor state in which point
Encoder count corresponding to information is transferred to controller.
Controller 103, for when hoist motor pressure is more than preset pressure, record elevator encodes
The initial reading of device；Real time readouts according to elevator encoder automatically controls with the relation of initial reading
Hoist motor stops promoting hammer ram, in order to controls hammer ram at the height that hammer ram promotes and falls；Wherein,
The height that the reacting condition hammer ram of the reading of elevator encoder promotes.
Specifically, once ramming in operation, after hammer ram firm landing hammer, hoist motor promotes hammer ram,
Hoist motor pressure F is gradually increased.When hoist motor pressure F is more than preset pressure f, permissible
Think that steel wire rope is strained, now record the initial reading N of encodern.It is pointed out that
Can be when promoting hammer ram every time, when hoist motor pressure F is more than preset pressure f, all records
The initial reading N of lower encodern.Such as, can be by the beginning of encoder during first time lifting hammer ram
Beginning reading N0, can be by the initial reading N of encoder during second time lifting hammer ram1, by that analogy.
Needs according to actual condition can choose the decision condition that hammer ram is automatically releasable.Due to elevator
The change of the reading of encoder can react the height that hammer ram promotes, therefore, according to elevator encoder
The relation of real time readouts and initial reading, it may be determined that whether hammer ram arrives specified level height
(surely ramming height mode), or may determine that whether the distance that hammer ram promotes arrives fixed vertical
Distance (surely ramming potential energy pattern), stops such that it is able to automatically controlling hoist motor by controller
Promote hammer ram.
The present embodiment can determine with the relation of the real time readouts according to elevator encoder with initial reading
The height that hammer ram promotes, and at this height, automatically control hoist motor stopping lifting hammer ram, in order to
Release hammer ram carries out ramming operation, and the automatic job accurately and quickly achieving dynamic compaction machinery controls, and carries
High working performance and homework precision.
Controller can determine fixed according to the relation of the real time readouts of elevator encoder Yu initial reading
Ram highly or surely ram and carry out under potential energy both of which ramming operation.
In one embodiment, surely ramming under height mode, controller is according to elevator encoder
When the relation of real time readouts and initial reading controls hoist motor stopping lifting hammer ram, specifically for:
Judge whether real time readouts is preset value with the difference of the initial reading of record when promoting hammer ram for the first time,
If preset value, control hoist motor and stop promoting hammer ram.
In another embodiment, surely ramming under potential energy pattern, controller is according to elevator encoder
The relation of real time readouts and initial reading control hoist motor when stopping promoting hammer ram, specifically for:
Judge when real time readouts and this promote hammer ram, whether the difference of the initial reading of record is preset value,
If preset value, control hoist motor and stop promoting hammer ram.
Determine above-mentioned two embodiment respectively below in conjunction with Fig. 2 and Fig. 3 ram height and surely ram
Two kinds of work patterns of potential energy illustrate.Assume that elevator encoder promotes hammer ram height H, corresponding volume
The reading raising encoder is changed to N, and above-mentioned preset value and preset value all could be arranged to H.
Fig. 2 is surely to ram height to act the schematic diagram rammed.Surely height is rammed certainly as in figure 2 it is shown, use
Dynamic release, when real time readouts and the initial reading promoting hammer ram record for the first time of elevator encoder
N0Difference when being N, represent that hammer ram rises to abswolute level height H at, now elevator encodes
The real time readouts of device is N+N0, controller controls elevator and stops promoting hammer ram, and carries out T time
Steady hammer.
Fig. 3 is surely to ram potential energy to play the schematic diagram of rammer.Surely potential energy is rammed certainly as it is shown on figure 3, use
Dynamic release, when real time readouts and this of elevator encoder promote the initial reading N of hammer ram recordn
Difference when being N, represent that the fixed vertical distance that hammer ram promotes is H, now elevator encoder
Reading is N+Nn, controller controls elevator and stops promoting hammer ram, and carries out T time and surely hammer into shape.
In actual applications, surely ram and be highly adaptable to ram ground hardness greatly, adjacent twice hammer ram
Fall the operating mode being more or less the same away from difference.Depending on potential energy to ram subject range wider, meet and ram and can require more
Precisely.Different work patterns can be chosen so that controller can be according to the reality of elevator encoder
Time reading control elevator stop promote hammer ram, then carry out the release of hammer ram.
In another embodiment of the control system of dynamic compaction machinery automatic job of the present invention, controller
103, it is additionally operable to after hammer ram lands, it is judged that whether compacting degree meets requirement；If compacting degree is not
Meet requirement, then control hoist motor and again promote hammer ram.

CPU carries out process to acceleration signal and obtains compacting degree.This process can be utilize compacting degree and
Ram the inverse relation formula of action time, calculate the rammer of the soil body action time according to ramming of hammer ram
Solidity.
Ram and can obtain according to the situation of change of acceleration action time, be set forth below two kinds and obtain
To the mode ramming action time.
Under a kind of mode, during single is rammed, when the acceleration of hammer ram is first equal to setting
During acceleration rate threshold, CPU trigger an intervalometer start timing, when hammer ram acceleration again
During equal to the acceleration rate threshold set, intervalometer stops timing, and timing time now is hammer ram
Ram action time.
Under another way, in order to obtain ramming more accurately action time, ram process at single
In, when the acceleration of hammer ram is first equal to the acceleration rate threshold set, CPU triggers one to be determined
Time device start timing, and trigger an enumerator simultaneously and start to measure number of samples, when adding of hammer ram
When speed is again equal to the acceleration rate threshold of this setting, intervalometer sum counter quits work simultaneously,
Now the timing time of intervalometer can be expressed as Δ T0, enumerator be counted as n, then hammer ram
Ram and can be expressed as Δ T=α Δ T action time0+ (1-α) n Δ t, wherein △ t is radio acceleration
In the sampling period of sensor, α can take 0.5.
As a preferred embodiment, controller 103, it is additionally operable to during hammer ram falls,
Judge whether the time that hammer ram falls reaches Preset Time and whether judge the reading of elevator encoder
Reach to preset reading；Preset Time and the reading of elevator encoder is reached in the time that hammer ram falls
When reaching to preset reading, control elevator braking.
Wherein, Preset Time (also expressing one's gratification the time of putting) can dispatch from the factory according to the vehicle of difference rammer energy
Before, in testing ground by the way of being gradually reduced t, determine the state reaching good not disorder cable
Time the time that puts soon t；It addition, in order to protect the reasonability put soon, set to elevator encoder
A fixed default reading n, presets reading n and such as can be arranged in the program of controller.
In the present embodiment, by double verification, i.e. when meeting preset time t and encoder simultaneously
When presetting reading n, controller just first cuts out brake by control electromagnetic valve group, closes after time delay
Clutch, to realize elevator braking, avoids hammer ram under the premise that security is guaranteed and lands disorder cable
Problem.
