Abstract
The invention relates to a rectification device of a trolley line power supply gantry crane cart, comprising a PLC controller, a laser distance meter and a subsidiary PLC controller, wherein, the subsidiary PLC controller is used for collecting data and calculating rectification. The subsidiary PLC controller is composed of a rectification calculating module, collects a data signal which is sent back by the laser distance meter and outputs the signal to the PLC controller as a switching value after rectification calculating; and the PLC controller controls the output and realizes rectification protection. The rectification device of the gantry crane has the main PLC controller and the subsidiary PLC controller, thereby solving the problems that the prior single PLC rectification device has heavy PLC burden and can not carry out complex calculation.
Description
Technical field
The present invention relates to a kind of correcting device of sliding contact line power supply gantry crane.
Background technology
Change electric improved gauntry crane through oil at present, increased the laser-bounce plate, adopt laser rangefinder that the walking deviation of cart is detected, to realize deviation rectification defencive function cart.The present this correcting device that utilizes the gantry crane of laser rangefinder, its data acquisition, correction computing and control output services all return a PLC by electric room independently to bear, cause the PLC burden in electric room heavier, can not carry out complex calculations, and change in the transformation process of electricity at gauntry crane oil, need the program changed many among the PLC.
Summary of the invention
The invention discloses a kind of correcting device of sliding contact line power supply gantry crane, this correcting device has major and minor two PLC controllers, and it is heavy to have solved the existing PLC burden of present single PLC correcting device, can not carry out the problem of complex calculation.
The technical solution used in the present invention is: a kind of correcting device of sliding contact line power supply gantry crane, have PLC controller and laser rangefinder, the secondary PLC that also has responsible data acquisition and correction computing, be composed of the correction computing module among the secondary PLC, secondary PLC controller is gathered the data-signal that laser rangefinder is passed back, exports to the PLC controller with switching value after the computing of rectifying a deviation.
Monitoring for convenience, described secondary PLC controller has touch-screen display.
The gantry crane driver monitors the operation conditions of cart for convenience, raises the efficiency and safety, and described PLC controller has touch display screen, sets up on the touch display screen in order to the voice prompting device of voice alarm and prompting to be provided.
The invention has the beneficial effects as follows: the correcting device of this sliding contact line power supply gantry crane has major and minor two PLC controllers, and it is heavy to have solved the existing PLC burden of present single PLC correcting device, can not carry out the problem of complex calculation.Secondary PLC controller is responsible for data acquisition and correction computing in this correcting device, control output after main PLC controller is responsible for rectifying a deviation, the running burden of main PLC is low, make correcting device can carry out complex calculations, running is stable, efficient improves, and change in the transformation process of electricity at gauntry crane oil, the program of the needs change among the main PLC reduces.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.

The specific embodiment
A kind of correcting device of sliding contact line power supply gantry crane, have PLC controller 1 and laser rangefinder 3, the secondary PLC controller 2 that also has responsible data acquisition and correction computing, be composed of the correction computing module in the secondary PLC controller 2, secondary PLC controller 2 is gathered the data-signal that laser rangefinder 3 is passed back, exports to PLC controller 1 with switching value after the computing of rectifying a deviation.Described secondary PLC controller 2 has touch-screen display.Described PLC controller 1 has touch display screen 11, and touch display screen 11 is provided with in order to the voice prompting device of voice alarm and prompting to be provided.
The correcting device of this sliding contact line power supply gantry crane has major and minor two PLC controllers; secondary PLC controller is gathered analog quantity, the switching value data signal that all laser rangefinders are passed back; according to the correction computing module of working out in it data of collecting are calculated; be transferred to main PLC controller with the switching value signal again; main PLC controller is responsible for control output, realizes the correction protection.Correction computing module in the secondary PLC controller has automatic deviation correction and manually rectifies a deviation two kinds, selects to use according to situation for the driver.
Increase secondary PLC controller be responsible for data acquisition with the correction computing after, the running burden of main PLC reduces, and makes correcting device can carry out complex calculations, and running is stable, efficient improves, and change in the transformation process of electricity at gauntry crane oil, the program of the needs change among the main PLC significantly reduces.
Secondary PLC controller is as data acquisition and display centre, for having realized that oil changes the gauntry crane that electricity is transformed, it can directly read data such as voltage that the parameters of electric power monitor records, electric current, power, electric energy, power, and as history data store in the storage card that it carries, make things convenient for the engineer to read analysis.The critical data that gauntry crane moves is in time understood, controlled to touch-screen display for the driver, the distance of voice prompting device prompting driver correction, or other operational promptings are provided, as fault or operation mistake etc.The driver can select automatic deviation correction or the mode of manually rectifying a deviation by touch display screen in driver's cab.
Secondary PLC controller is as data acquisition and display centre, can also gather parameters such as diesel engine power supply, slide wire power supply, freight container switching lock signal, realize the statistical analysis of related data, particularly, help maintainer and operating personal in time to grasp the real time data that gauntry crane moves at the gauntry crane data of productive output, energy consumption contrast statistical analysis under diesel engine power supply and slide wire power supply state respectively.
This correcting device also has computer supervisory control system, computer supervisory control system comprises local monitor station and remote service control station, the local monitor station is used to obtain and analyzes big wheel paths history, and analyzes data such as the voltage of gauntry crane under the diesel oil power supply or under slide wire power supply, electric current, energy consumption; The remote service control station is responsible for the various operating datas at Central Control Room remote monitor and control gauntry crane.
