Description
Technical field
The present invention relates to automation field, particularly relate to a kind of paver level control method and system.
Background technology
The level sensor configuration that paver level control system exists at present is single, and system is to other types sensor not
Compatible problem.Specific as follows:
One, the automatic control system level sensor to being equipped with in material position requires strict, and type selecting is single:
Either manufacturer or terminal use user, be limited in and can only use a certain regulation model or shape
The level sensor of formula, the material position automatic control system of paver in addition other forms or the level sensor of type,
Can not be compatible.
Two, the material position automatic control system level sensor to being configured, it is impossible to carry out adjustment and the amendment of relevant parameter:
The material position automatic control system of paver at present, even if being mounted with the level sensor of regulation model or form, skill
Art personnel, manufacturer or terminal use user, this level sensor can not be carried out parameter configuration, and this is necessarily
The maximum performance of level sensor performance is limited in degree.
The two above problem existed for the material position automatic control system of current paver, illustrates:
Such as, the material position automatic control system of certain XG151201 type paver, use current common control system, just need
Being equipped with 4 the level sensors of output " special A type electric currents ", this sensor must have a following opering characteristic of electric apparatus: 1, specified work
Make voltage 24 volts；2: range of current output: 150～650 milliamperes.And practical situation is, substantial amounts of sensor, the output electricity of standard
Stream is 0～20 milliampere or 4～20 milliamperes, exports the sensor of 150～650 milliamperes, can only be customization, this mesh the most just
Front system needs to configure the reason of " sensor special ".But work as plant maintenance, transformation, upgrading, need to use other forms to sense
Device, such as the Type B sensor of voltage output, the c-type sensor of switch output, the D type sensor of electric current 0～20 milli output, then
The most all can not use.
Such as, the level control system of current paver either technological development personnel or terminal use client, it is possible to
Control, control this sensor simply by the power supply controlling " level sensor of special A type electric current output " and be in " work
Make state " it is in " quit work state ", " level sensor of special A type electric current output " adds power source, by output about
The electric current of 150 milliamperes, then, along with the change in location of this sensor detection faces, the output electric current of sensor can be gradually increased, directly
Reaching about 650 milliamperes to electric current.Really, when level sensor is output as 150 MAHs, it is can not drive hydraulic system principle
Loaded work piece, say, that equipment is really in " quit work state ", equipment is in the electricity of " duty "
Stream, it is generally required at about 250 milliamperes, then, between 150～250 milliamperes, equipment is to be driven, idle.Work as biography
When sensor output reaches about 550 milliamperes, generally, equipment is already at maximum rating, at this moment, is further added by
Electric current, is substantially null(NUL), say, that in the case of actually used, and the output current scope of level sensor is preferably
Between 250～550 milliamperes.If this biosensor output parameter can be adjusted so that it is output changes into 250～550 milliamperes, and not
It is 150～650, the most substantially, the response time of equipment can be shortened, improve actuating speed, improve efficiency.
More than having problems, limit the automaticity of equipment, suitability to a certain extent, system is to other shapes
Formula, type sensor incompatible, can not configure, result also in maintenance, change the problem that new sensor is inconvenient.
