Abstract

The no-contact crane controller is one kind of crane controller with long service life of the motor, high reliability and capacity of lowering labor strength. The no-contact crane controller consists of a small master controller, a micro controller, a computer, a display and a solid state relay. The program compiling interface values are fed to the computer, downloaded to the micro controller, treated in the monolithic computer and saved in the EPROM. When the small master controller sends out command, the micro controller outputs essential program, the solid state relay is driven to act and the crane executing motor is controlled to operate to execute the command. The present invention is used in controlling small crane.

Description

No-contact crane controller
Technical field
The present invention relates to a kind of crane operation control setup, specifically is a kind of no-contact crane controller of little tonnage.
Background technology
At present the crane facility of industries such as mine, metallurgy, storage is based on the specification below 30 tons, and its control system is many all with the cam mechanism control desk or be equipped with the control panel realization speed governing of each mechanism of hoisting crane is not still had the electric contact control mechanism.There is following defective in this control mechanism: 1, control desk is a kind of hand gear.The control contact folding speed that inserts the drive motor major loop is slow, and the contact is very big by electric current, easily causes electrical arc erosion, influences the control mechanism normal operation, and has a strong impact on the performance performance of back level work electrical equipment; 2, contact need be used high-grade rare metal such as Agcdo manufacturing, and consumption is big, the cost height, and the manufacturing process environmental pollution is serious, the tenure of use that country has stipulated this material, bans use of to after date; 3, the easy scaling loss of contact causes frequent parking to change contact, and the frequency of maintenance height causes use cost big, and efficiency is low; 4, control mechanism adopts the cam pack of One's name is legion, will constantly overcome the spring force that guarantees the contact through-current capability in the operation, and operation labour intensity is big; 5, distance is generally 50 meters of 30 ∽ from the control desk to the resistance box, 40 of used copper core 20 ∽, and the wire rod consumption is big, equipment cost of installation height; 6, fault in-situ maintenance difficult, when the pass program of closing had fault, the scene can't be keeped in repair, and can only get rid of by making manufacturer, influenced normal operation.
Summary of the invention
Existing crane controller functional reliability is poor, labour intensity big in order to solve, manufacturing and the high problem of maintenance cost, the invention provides the no-contact crane controller that a kind of performance sensitive is reliable, easy and simple to handle, use cost is low.
Technical scheme of the present invention
No-contact crane controller comprises control system and actuating unit, control system of the present invention is by little master controller, microcontroller, computing machine, telltale is formed, sets of contacts is equipped with in the handle bottom of little master controller, by several some kinds of open and-shut modes are determined by operating habit in the contact, and send instruction to microcontroller, realize the control program of crane controller by microcontroller, microcontroller comprises programming control and solid-state relay actuating device two parts, wherein contain micro controller system, the electricity flash memory, shift register, latch, actuator and RS232 interface, interface links to each other with computing machine, after computing machine input " user closes required pass table output program editing interface " value, run application, and import little master controller pass and close state table, handle through micro controller system, with application storage in electric flash memory, after microcontroller receives instruction, by its instruction signal is passed to actuator, to drive the work of actuating unit solid-state relay group, the break-make of control solid-state relay, the action of manipulation crane executing mechanism, telltale shows the mode of operation of solid-state relay group.
Beneficial effect of the present invention is compared with prior art, the present invention has following advantage: 1, use the control contact of solid-state relay as drive motor, no longer, guaranteed the performance of motor performance effectively, improved the service life of motor with by the very big mechanical contact of electric current; 2, behind the little master controller of use, do not had cam pack, made crane operation light, flexible, reduced labour intensity; 3, little master controller, microcontroller and the connecting cable in the device is can general-duty in hoisting crane control category, and solid-state relay press only 4 kinds of 3 ∽ of current class branch, and this has just significantly reduced the tank farm stock of the former device of hoisting crane applying unit; 4, system works is reliable, and fault rate is low, and trouble tracing is convenient, and is easy to maintenance, thereby improved production efficiency; 5, when needs microcontroller and solid-state relay group and the installation of little master controller strange land, can save a large amount of connecting cables; 6, because this device reliable working performance, fault rate is very low, thus stopped because of user and the side of manufacturinging in earlier stage less in linking up, the problem that the user can't handle when making the product pass close program and operating needs not to be inconsistent.

The specific embodiment
Specify embodiment of the present invention below in conjunction with accompanying drawing.Be combined on the circuit card by each element electricity flash memory 6, micro controller system 8, shift memory 9, latch 10, actuator 11 and the RS232 interface 7 with microcontroller 3 shown in Figure 2, form system by Fig. 1 again, little master controller 1 is connected on the input end of microcontroller 3, connect telltale 2, computing machine 5 and solid-state relay group 4, load onto fault-indicating lamp and alarm buzzer, after the input operation instruction, behind microcontroller 3 programming controls, pass to the solid-state relay group 4 that fast quick-break is closed, handle the work of hoisting crane drive motor by actuator 11.Use the plug receptacle of standard to connect in the system between each assembly.
The table application program is closed in pass in the operation computing machine 5, ejection " user closes required pass table output program editing interface " is imported little master controller pass as required and is closed state table, operation procedure, signal passes down, send into microcontroller 3, its application program writes in the electric flash memory 6 after micro controller system 8 is handled, and control program as required can be erasable repeatedly, to realize operating needs.
The sets of contacts of little master controller 1 is made up of four pairs of contacts, chooses as shown in Figure 4 13 kinds of open and-shut modes by operating habit, is divided into left each 6 grades to the right.When microcontroller 3 receives the pass that does not belong to shown in Figure 4 when closing state, buzzer phone is promptly reported to the police.
Little master controller 1 and microcontroller 3 can be general in hoisting crane control is used, and are convenient to realize normalisation.
Telltale 2 is used for monitoring the service condition of solid-state relay group 4, when needs use touch-screen, then can touch-screen realizes the control to solid-state relay group 4.
Solid-state relay group 4 is general-duties, and its quantity can reach as high as 21 the tunnel by the output channel requirement.
Little master controller 1, microcontroller 3, solid-state relay group 4 can be combined in the control box, and microcontroller 3 and solid-state relay group 4 can be installed in the strange land in 200 meters scopes with respect to short metre for poems that contains relatively few syllables controller 1.
Adopt the mechanical contact in the existing control mechanism among the present invention, so be called no-contact crane controller by term in the industry.
