demonstrating working altitude. Adopt bilingual display of middle English , the amicable man-machine interface , may make a consumer use appearance according to the upper hint of screen , fleetness operation and rightness.
? Have provided time display and fast display of hook , have provided to the driller besides demonstrating the altitude outside, to facilitate.
? Has the adopt stainless steel to touch a keyboard , artistic but unaffected , water-proof the strong point sealing off , handling a Q-percentile life, malfunction are few.
? Adopt good , artistic but unaffected to pull lines stainless steel as printing plate , overall effect.
? The sensor adopt peculiar circuit and machine work , the job is stable.
Technology index
? The altitude demonstrates range： -4～40.00m ? Simulate display range： -4～35.00m
? Defend against touch altitude range：0～35.00m ? Early warning distance sets up range：2～9m ? Defend against touch output： DC24V
? Import a power source： AC200V±15% 50～60HZ ? Power is consumed： ≤15W
? Use temperature range： -20℃ ～ 80℃
Operating principle
That the floating drilling machine vehicle altitude number displays defending against touching an instrument is that big petroleum drilling machine hooks run altitude instruct and defend against touch the automatic monitoring device controlling. The microcomputer controller can pass input initial parameter: Cylinder diameter , the effective length of cylinder , steel wire rope diameter , pulley block number, the each tier calculating out a cylinder winds the rope number of turns averagely. Pass the input operation parameter: The present calculating out cylinder revolution as well as the initial tier of numbers and initial tier of circles number, getting the cylinder angular displacement from
the sensor winds the down big rope diameter hooks operation route or distance of travel. The steel wire rope that initial state , the microcomputer controller demand to import big hooks on highly lower drill table top roller spindle composes in reply tier a number of turns , the sensor collects the cylinder angular displacement signal , the microcomputer chip , course importing central authority controller secretly scheme against the queen , get big hooks operation altitude, and shape liquid crystal and the character liquid crystal screen are hit by display in post immediately the simulation and digital big hook altitude , begin to give an alarm and comparing with already set up having gone ahead in advance defending against touching an altitude, while getting to the line giving an alarm, Get to the connection signal controlling the valve effluence to electricity- gas when going ahead defending against touching location, the gas control valve conducts an electricity- defending against under the control of touching organization action , come true defending against touching safe operation.
Handle explanation
1. Start up
Finish linking sensor cable and feed cable , open up , pursue as follows according to \ source\：
When seeing the tableau
above,having pushed down a
key or being burning the language that the key , choice need down.
2. Interface working regularly
Language
choice has completed the day afer tomorrow , will have entered the interface working regularly, has pursued as follows:
The regular job has figure altitude , speed , time and operation simulating altitude , the hook to point out display on the interface.

3. The parameter is set up
In the interface working regularly, need to think of set-up parameter , can enter a parameter if the menu interface, pursuing 1 according to \
