Description
Technical field
The utility model relates to a kind of automatic alarm circuit, and specifically a kind of dynamo bearing chilled water interrupts automatic alarm circuit.
Background technology
Cooling water recirculation system is the important step of whole dynamo bearing, and former way of supplying water adopts manual control always, and the water after using is without circulation, and directly outer row, waste is very large, also there is the problems such as water quality inferiority, water shortage, hydraulic pressure are low simultaneously.Therefore, generator each bearing cooling water water circulating pump station automatic control system is imperative, and the general cost of existing system is higher, and stability is not high, is not suitable for promoting the use of.
Utility model content
The purpose of this utility model be to provide a kind of energy-saving and cost-reducing, reliablely and stablely dynamo bearing chilled water interrupt automatic alarm circuit, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of dynamo bearing chilled water interrupts automatic alarm circuit, comprise single-chip microcomputer, PLC, testing circuit, water pump and power supply, described power supply connects water pump and PLC respectively, described PLC also connects single-chip microcomputer and water pump respectively, described water pump also connects single-chip microcomputer by testing circuit, described single-chip microcomputer also connects display, keyboard and hummer respectively, and described testing circuit comprises temperature sensor, pressure transducer, flow sensor and current sensor.
As further program of the utility model: described PLC type number is mitsubishi FX2N-32MR, described single-chip microcomputer model is PIC18F2480.
As the utility model further scheme: temperature, pressure, flow and current signal are converted to standard signal by temperature sensor, pressure transducer, flow sensor and current sensor and pass to single-chip microcomputer by described testing circuit, single-chip microcomputer is by after described standard signal is compared with the various signal higher limits of keyboard to set up, communicate with PLC again, thus control water pump, display, keyboard and hummer.
Compared with prior art, the beneficial effects of the utility model are: this use is novel by using PLC automatic control technology, by the appropriate design to software and hardware, make whole dynamo bearing chilled water interrupt the overall cost of automatic alarm circuit to decline to a great extent, energy-saving and cost-reducing and reliable and stable during system cloud gray model.
Accompanying drawing explanation
Fig. 1 is the structured flowchart that dynamo bearing chilled water interrupts automatic alarm circuit;
Fig. 2 is the I/0 distribution diagram that dynamo bearing chilled water interrupts PLC in automatic alarm circuit;
Fig. 3 is that dynamo bearing chilled water interrupts temperature detection part Single Chip Microcomputer (SCM) system structured flowchart in automatic alarm circuit.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 3, in the utility model embodiment, a kind of dynamo bearing chilled water interrupts automatic alarm circuit, comprise single-chip microcomputer, PLC, testing circuit, water pump and power supply, power supply connects water pump respectively and PLC, PLC also connect single-chip microcomputer and water pump respectively, and water pump also connects single-chip microcomputer by testing circuit, single-chip microcomputer also connects display, keyboard and hummer respectively, and testing circuit comprises temperature sensor, pressure transducer, flow sensor and current sensor.
Refer to Fig. 2, PLC type number is mitsubishi FX2N-32MR, and this PLC has each 16 of input and output I/O point, and wherein the utility model uses input 15, exports 13, leaves the redundancy of 12.5% altogether, for expanding needs later.
Single-chip microcomputer model is PIC18F2480, adopt single-chip microcomputer as conversion portion, disperse the controlling functions of whole control system, the number of the I/O point of the PLC used in whole system can be reduced, reduce the cost performance of whole system, and adopt single-chip microcomputer inherently high than employing PLC as conversion portion hardware, single-chip microcomputer PIC18F2480 is a single-chip microcomputer being integrated with a lot of module, function is quite powerful, and reliable.Adopt single-chip microcomputer as conversion portion time by the restriction of distance, can input become send after directly change.
Temperature, pressure, flow and current signal are converted to standard signal by temperature sensor, pressure transducer, flow sensor and current sensor and pass to single-chip microcomputer by testing circuit, single-chip microcomputer is by after standard signal is compared with the various signal higher limits of keyboard to set up, communicate with PLC again, thus control water pump, display, keyboard and hummer.
