Embodiment Construction

[0014] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. As shown in Figure 2, the components of the microcontroller 3, the EEP memory 6, the single-chip microcomputer 8, the shift memory 9, the latch 10, the driver 11, and the RS232 interface 7 are combined on a circuit board, and then formed according to Figure 1 system, connect the small master controller 1 to the input terminal of the micro-controller 3, connect the display 2, the computer 5 and the solid state relay group 4, install the fault indicator light and the alarm buzzer, after inputting the operation command, the After the microcontroller 3 program control, the driver 11 transmits it to the solid-state relay group 4 of fast disconnection to operate the crane to drive the motor to work. The components in the system are connected by standard sockets.

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

technical field [0001] The invention relates to a crane operation control device, in particular to a small tonnage non-contact crane control device. Background technique [0002] At present, the crane equipment in mining, metallurgy, storage and other industries is mainly under 30 tons, and its control system mostly uses a cam mechanism console or a control panel to realize the speed regulation of each mechanism of the crane, and there is no electric contact control mechanism. . There are following defects in this control mechanism: 1, console is a kind of manual mechanism. The opening and closing speed of the control contacts connected to the main circuit of the drive motor is slow, and the contacts pass through a large current, which may easily cause arc burnout, affect the normal operation of the control mechanism, and seriously affect the performance of the subsequent working electrical appliances; 2. Contacts It needs to be made of high-grade rare metals such as silve...
