Description
Technical field
The present invention relates to a kind of intelligent control system of novel ac solid relay, it can be used for Mechatronic control system and programmable logic control system.
Background technology
Along with the high speed development of electronics, computer technology, increasing considerably of onboard electrical equipment, has had higher requirement to the control of electrical load.In order to adapt to new development need, studying novel electrical load control system becomes the task of top priority.
In current Mechatronic control system and distribution system, generally there are two kinds of formulas to the control of electrical load: isolating switch and solid-state relay.These two kinds traditional control modes have a lot of not enough place: as guard time is slow, the life-span is low, do not possess health control and initiatively implementing monitoring function.
Beneficial effect of the present invention
The object of the present invention is to provide a kind of intelligent control system of novel ac solid relay, solve prior art guard time long, the life-span is short, does not possess the problems such as health control.
To achieve these goals, technical scheme of the present invention is as follows: a kind of intelligent control system of ac solid relay, comprise digital-to-analog conversion control module and export and control control module, it is characterized in that: the electric current that analog-to-digital conversion module is changed by mutual inductor gathers, analog quantity is converted into digital quantity, issue and turn on and off electrical load order and status inquiry command, 3 LED indicate, and simultaneously outside programmable logic controller (PLC) will receive current instruction.Show current state by host computer simultaneously.
Accompanying drawing explanation
Fig. 1 is overall hardware system structure schematic diagram of the present invention.
Fig. 2 is overall software system structure schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
In FIG, work as system electrification, this time, by outside or by programmable logic controller (PLC) to central processing unit signal, carry out initial demarcation.If do not demarcated, when first time uses, amber light in status indicator lamp and green light can symmetrically glimmer, represent that present system is not in running order, use if not first time, system can read this data from the storage space of data, because data exist inside EEPROM, even if so power down also can retain data.
The method of demarcation can be found out in fig. 2, first a signal more than 3 seconds will be given, system will force output signal to solid-state relay in the meantime, solid-state relay is caused to force conducting, and by electric current now, changed by mutual inductor, process to central processing unit, status indicator lamp amber light and green light can glimmer fast in the meantime, after time of signal was more than 3 seconds, central processing unit, by this signal write EEPROM, is kept, when normally running, central processing unit from value inside EEPROM out.If the normal value preserved exceeds this scope of 2-50A, preserve numerical value invalid, need again preserve.Data are passed to host computer by wireless module and show by central processing unit.
When normally working, amber light and red light are in always bright state, if green light glimmers at a slow speed suddenly, illustrate that now, open circuit appears in circuit part, if now amber light extinguishes, green light fast blink, illustrates now circuit breaker.If green light fast blink, amber light or light yellow, illustrate now circuit overloads.
If programmable logic controller (PLC) does not send signal to central processing unit, system is not also in debugging mode, if now solid-state relay conducting, that illustrates that short circuit appears in solid-state relay, and this is that system will only have when red, carrys out indication mechanism fault with this.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
