A farmland is then turned on irrigation sprinkler and realizes sprinkling irrigation operation.But due to the farmland under conditions of mechanized production often area compared with
Greatly, the PE pipes of irrigation sprinkler are longer, and during towing vehicle pipe laying, it is too fast often to will appear pipelaying rate, so as to cause gear
Case gear shaft rotates too fast so that reducing the situation that service life even fractures on the spot, this just affects the irrigation sprinkler later stage
Working effect and normal production operation.
Second, due to its working time ten more than hour easily, people can not monitor disk type spray in real time during this period
The working condition of filling machine.When reel sprinkling irrigation machine works, sprinkler car recycles automatically under the traction of plastics PE pipes, removal process
In, because will appear, power failure is cut off the water, hydroturbine blocks, gear-box extension shelves are unreliable leads to PE pipe capstan winches to out of supply etc. sometimes
The case where stalling, causes to delay respectively and pours and excessively pour, and often the sprinkling irrigation failure of irrigation sprinkler can't obtain clearly in time
Except so as to cause unnecessary loss.

Dynamic backhaul continues to twine next layer of pipe.It is corresponding to it, the characteristics of speed display system provisioned in domestic sprinkler with reel is to test the speed
Velocity measuring shaft selected by sensor is the 1st grade of axis, i.e. line shaft of reduction gear box, and operator is each time it is to be understood that current PE pipe
Speed is recycled, the number of plies of PE pipes on capstan winch at that time will be manually entered, then input the gear number that current gear case is mounted, in conjunction with
The two parameters rely on the pulse signal frequency that the sensor on velocity measuring shaft obtains, velocity indicator that can calculate automatically currently again
The recycling speed of PE pipes, and show, but there are one defects for this system, be exactly only reacting the speed of closed tube, can not embody
The speed of pipe laying, and the reduction gear box of specific transmission ratio must be matched, which has limited the subsequent designs of reduction gear box to change

This piece of Hall switch sends out 1 pulse to master controller, master controller according to system program setting, it is believed that the number of plies increases
（Actual conditions are also really such）, the closed tube number of plies is shown+1 automatically, and stablize display, executes the recycling linear velocity for calculating PE pipes
When, it also can be worth the trigger condition as a result, until receiving next number of plies+1, i.e. Hall switch II- according to the new number of plies
12 or Hall switch III-13 detects the close of magnet 16 and sends pulse signal again.
In Fig. 4, display screen is touch screen, and is connected with master controller, is placed in master controller encapsulated plastic box.
In Fig. 5, master controller is the core of system operation.
In Fig. 6, the display project of display screen includes：Battery capacity, display numerical value unit is %, and system charge is as straight
The electricity for flowing accumulator, monitors it and is realized by the monitoring cell electricity quantity module in Fig. 2, for assisting user's estimation to work as preceding article
The charge efficiency of system and its persistence of operation under part；Recycle the number of plies, layer of the display current PE pipe 2 wound on capstan winch 3 thereon
Number calculates the reference factor of recycling speed as master controller, and its initial value can be manually changed by user；Recycling speed
Degree, display numerical value unit is m/h；Warning function starting state, corresponding is manual palpation button, only " ON " and " OFF " two
A value, respectively represents whether warning function is in " awaiting orders " state；Subscriber phone, input value are GSM electricity when alarming to send out
The subscriber directory number of road module " remote alarms " calling, value are manually entered for user, can arbitrarily change at any time.
When in use, i.e., during pipe laying or closed tube, guiding leading screw axis 15, is oriented to what shift fork 10 was constituted at guiding leading screw set 9
PE pipes 2 are fitly arranged on capstan winch by comb guiding mechanism.As shown in Figure 5 and Figure 6, necessarily there is guiding in the ultimate position of closed tube
Screw set 9 is in position corresponding with PE pipes, and closed tube terminates every time, this position will not change.Using this principle, in guide wire
One piece of magnet 16 is installed in the top of thick stick set 9, and in leading screw cover 17 in the φ ' length of this position, installs Hall switch IV14,
Once during closed tube, guiding leading screw set 9 experiences the magnetic field of magnet 16, sensor meeting when by immediately below sensor
Pulse signal is sent out to master controller, if recovery layer numerical value at that time is exactly the outermost layer on capstan winch 3, according to system
The program of setting, master controller will be considered that " nearly machine alarm " condition is triggered, and to send out alarm, prompt operator's nozzle on duty
Vehicle 1 can take corresponding safety measures already close to host, in order to prevent failure of apparatus out of supply.And when alarming, sprinkler car 1
Space length apart from host is m=φ ' × n/ φ, wherein n represents the length of 3 outermost layer PE pipes 2 of capstan winch winding, 1 circle, φ generations
The diameter of table PE pipes 2.Detecting that it is outermost that capstan winch 3 has received PE pipes 2 according to acoustooptic alarm system described above, of the invention
When layer, the pulse signal that Hall switch IV14 is transmitted is collected, as close machine signal.This system is passed through in JP75/300 disk types
It installs and tries out on irrigation sprinkler, realize the function of this monitoring system, effect is ideal.
The capstan winch 3 of reel sprinkling irrigation machine acquires the rotating speed of velocity measuring shaft by sensor in real time in rotation process, further according to
The 2 place number of plies of PE pipes, system can calculate PE pipes 2 automatically according to built-in formula procedure and recycle linear velocity, and be given by display
With display, when laying PE pipes 2, operator on duty successively decreases number of plies registration manually according to 2 actual layer number of PE pipes, once system obtains
It is more than 2000m/h that PE pipes 2, which recycle speed, that is, is alarmed, and to prompt pipelay operation person's pipe laying to exceed the speed limit, should reduce pipe laying speed
Degree.Pipe laying is ended, and after power hangs shelves, irrigation sprinkler just starts closed tube, and the initial number of plies on capstan winch 3 where PE pipes 2 is by user
It sets, during subsequent closed tube, once the magnet 16 installed on conduit shift fork 10 touches the sensing on 3 bracket lip edge of capstan winch
Device, then be the beginning that capstan winch 3 winds next layer of PE pipe 2, and sensor can send out the increased pulse signal of the number of plies automatically so that control
Device calls the calculation formula of the corresponding number of plies when internal calculation PE pipes 2 recycle speed automatically.Conduit shift fork 10 and conduit screw set 9
It is integral piece, in closed tube, its motion mode is linear reciprocating motion.Since when closed tube ends, conduit screw set 9 is in conduit
Position in lead screw shaft 15 is fixed, so designing in upper and actual use, when conduit screw set 9 is in closed tube ultimate position
A preceding caliber apart from when, then it is assumed that it is unrecovered come 2 length of PE pipes be 3 outermost layer of capstan winch winding one circle when pipe range,
According to this rule, one piece of magnet 16 is mounted on conduit screw set 9, there are one the hanging top arrangements of guiding leading screw set 9
Sensor, once sensor detects guiding leading screw set 9 by that below, then can send out pulse and be transmitted to controller, and capstan winch 3
Closed tube state is in recycling outermost layer PE pipes 2, then controller will be considered that sprinkler car 1 already close to capstan winch 3, sends out alarm signal immediately
Number, operator on duty is called to carry out manually handle cut-out transmission, this function is known as " nearly machine alarm ".When PE pipes 2 recycled
