Abstract
The utility model relates to a control system based on a field frequency-conversion starter on a frequency-conversion rolling bed. The field frequency-conversion starter is connected with a control terminal of a frequency-conversion rolling bed drive motor, as well as a main control PLC (programmable logic controller) through a fieldbus; and a frequency-conversion rolling bed position-occupying sensor, a frequency-conversion rolling bed speed-reducing sensor, and a frequency-conversion rolling bed halting sensor which are mounted on a frequency-conversion rolling bed, are connected on the fieldbus. The control system fully utilizes the PLC (programmable logic controller) to control the field frequency-conversion starter according to DevicenNet fieldbus protocol, and utilizes the field frequency-conversion starter to drive a filed motor through the field frequency-conversion starter without point-to-point wiring, thereby achieve low labor intensity, fast and convenient diagnoses faults, wires connection through a connector, and high wiring efficiency; the complicated selection of electric elements is not required, so that the time of engineering and design is reduced, and the space of a central control cabinet is reduced; the protection grade reaches IP67; and the modularization and standardization degree is high.

Background technology
Along with improving constantly of the on-the-spot frequency conversion starter consciousness of people, understood the equipment that how to design, make, use on-the-spot frequency converter, how to buy the equipment of the on-the-spot frequency conversion of check, how on-the-spot frequency converter equipment is managed.Add the develop rapidly of electronic technology, the fusion innovation of every profession and trade subject, also more and more higher to the standardization requirement of on-the-spot frequency conversion equipment.The theory of on-the-spot frequency converter all-in-one also is subjected to positive popularization.
Under above-mentioned environment, various on-the-spot frequency converters expose one after another, and on-the-spot frequency conversion starter is a kind of integrated, pre-on-the-spot frequency converter of installing, and on-the-spot frequency conversion starter is mounted in the solid-state on-the-spot frequency converter on motor next door.And integrated on-the-spot I/O, the DeviceNet field-bus interface.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of and roll a control system of last on-the-spot frequency conversion starter based on frequency conversion, be used for the vehicle body process and roll bed and the high fabrication line process of breakneck requirement of shelter, and can safely, effectively realize robotization control.
The technical scheme that provides according to the utility model, describedly roll a control system of last on-the-spot frequency conversion starter based on frequency conversion, the control end that rolls a drive motor in frequency conversion connects on-the-spot frequency conversion starter, and described on-the-spot frequency conversion starter connects main control PLC by fieldbus.
The degree of protection of on-the-spot frequency conversion starter is IP67.
Also be connected with on the described fieldbus and be installed in frequency conversion and roll that an occupancy sensor is rolled in frequency conversion on the bed, a deceleration sensor is rolled in frequency conversion and a stop sensor is rolled in frequency conversion.
The utility model makes full use of PLC and controls on-the-spot frequency conversion starter by the DeviceNet field bus protocol, and on-the-spot frequency conversion starter drives on-the-spot motor, and its advantage has:

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
This scheme is that to be used in combination with on-the-spot frequency conversion starter and on-the-spot motor be platform.As shown in Figure 1: the control end that rolls bed 3 drive motor in frequency conversion connects on-the-spot frequency conversion starter 2, and described on-the-spot frequency conversion starter 2 connects main control PLC 1 by fieldbus.On-the-spot frequency conversion starter 2 is installed on frequency conversion and rolls near bed 3 drive motor.Also be connected with on the fieldbus and be installed in frequency conversion and roll that an occupancy sensor 6 is rolled in the frequency conversion of bed on 3, a deceleration sensor 7 is rolled in frequency conversion and a stop sensor 8 is rolled in frequency conversion.
The control of the on-the-spot frequency conversion starter 2 of sequential testing in rolling bed operating according to Fig. 1～Fig. 4.
The first step: when sled 4 band vehicle bodies 5 were run into frequency conversion and rolled a bed occupancy sensor 6, frequency conversion was rolled bed 3 and is started at a high speed and just change, as shown in Figure 2.
Second step: sled 4 band vehicle bodies 5 just change at a high speed, run into frequency conversion until sled 4 and roll a deceleration sensor 7, and sled 4 band vehicle bodies 5 stop just to change at a high speed, and sled 4 band vehicle bodies 5 low speed just change, as shown in Figure 3.
The 3rd step: sled 4 band vehicle bodies 5 low speed just change, and run into frequency conversion until sled 4 and roll a deceleration sensor 8, and sled 4 band vehicle bodies 5 shut down, as shown in Figure 4.
The utilization of on-the-spot frequency conversion starter 2 in auto production line is extremely important.The degree of protection of described on-the-spot frequency conversion starter 2 is IP67, is used in the position abnormally dangerous, that requirement of shelter is high, can guarantee the safety of the person and machinery and equipment.The use that combines of on-the-spot frequency conversion starter, sensor, machine fortune equipment.Just constituted a complete production line control system.The safety signal of on-the-spot frequency conversion starter sends to programmable logic controller (PLC) (PLC).PLC received signal, and make instruction, and can automatic fault reporting to the police, the record trouble spot makes machinery and equipment be in state to the person and machinery and equipment safety.
