Description of drawings
In order to be illustrated more clearly in embodiments of the present invention, to do one to the accompanying drawing of required use in the embodiment below introduces simply, apparently, accompanying drawing in describing below is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structured flowchart of a kind of embodiment of contact relay control of electrical equipment start and stop control device of the present invention.
Fig. 2 is the structured flowchart of the another kind of embodiment of contact relay control of electrical equipment start and stop control device of the present invention.
Fig. 3 is the structured flowchart of existing contact relay control of electrical equipment start and stop control device.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and, this programme is set forth, but the invention is not restricted to following embodiment in conjunction with its accompanying drawing; And the electrical equipment described in the described embodiment is the contact relay control of electrical equipment of separate operaton.
Fig. 3 is the structured flowchart of existing contact relay control of electrical equipment start and stop control device, and it uses the single output of PLC set control mode, and as known in the figure, the PLC controller only links to each other the contactor control of electrical equipment by an auxiliary reclay with contactor.The PLC controller by an auxiliary reclay control of electrical equipment startup and stop, in case auxiliary reclay interrupts because of the PLC controller failure, electrical equipment then can't operate as normal, thereby influences normal production and supply.
Fig. 1 and Fig. 2 are two kinds of embodiments of contact relay control of electrical equipment start and stop control device of the present invention, and hence one can see that, electrical equipment start and stop control device of the present invention comprises PLC controller, contactor and is used for the scram button that electrical equipment promptly stops, and described contactor connects electrical equipment; This device also comprises the auxiliary reclay that stops that being used to receive the startup auxiliary reclay of electrical equipment enabling signal and being used to receive the electrical equipment stop signal, and the auxiliary normally opened contact that described startup auxiliary reclay connects the coil of described contactor, described contactor links to each other with described startup auxiliary reclay; Described PLC controller connects the PLC fault alarm.
