Abstract
The utility model discloses a circuit used for automatic detection and alarm, which comprises a PLC (programmable logic controller) module, a relay, an indicator light and a switch power supply. The switch power supply provides electricity for the PLC module which is connected with devices required to be detected and monitored to receive device status signals, and the PLC module drives the relay to open or close so as to control the indicator light to flash according to the device status signals. The circuit is simple in principle, easy to realize, obvious in warning effect, capable of sending different alarms according to specific conditions, and more intelligentized and humanized.
Description
Technical field
The utility model relates in some main equipment systems of some high pressure or dangerous character.At having high pressure, be used for the circuit that detects and report to the police automatically in the system of radiative property especially.
Background technology
Have in the equipment of nature of danger at some, such as high-tension apparatus, radiating system etc., often noiseless, colourless, tasteless in the process of operation, be difficult for being discovered by the people, but itself can cause great bodily injury to close people's personal safety, thus must in the environment around alarming sign be set, so that near people is played warning function.
Way is in the past established a warning sign in the environment often around, perhaps fences up with railing, and some then sends special people to go to be in charge of.More or less there is drawback in these ways, and are not eye-catching such as warning sign, are difficult for drawing attention, and managerial personnel's grade off one's guard all might cause substantial risk and unnecessary loss.
The utility model content
The technical problems to be solved in the utility model be realize a kind of in equipment running process the state according to equipment detect automatically and warn.
To achieve these goals, the technical solution adopted in the utility model is: a kind of circuit that is used for detection automatically and reports to the police, this circuit comprises PLC control module, relay, pilot lamp, Switching Power Supply, described PLC control module is powered by Switching Power Supply, the equipment that detects monitoring with need is connected, receive its equipment state signal, and drive the flicker of relay closure or openness control pilot lamp according to this signal.
Described pilot lamp is divided into three groups, is respectively green light pilot lamp, amber light pilot lamp and red light pilot lamp, the pilot lamp flicker that described PLC control module is different according to the status signal control of watch-dog.
Described green light pilot lamp, amber light pilot lamp and red light pilot lamp respectively are provided with 6 groups respectively.
Described PLC control module is connected the keying of controlling outer tapper with the alarm bell supply module.
Advantage of the present utility model is that circuit theory is simple, is easy to realize, the caution effect is obvious, and can make different cautions as the case may be, and it is intellectuality and hommization more.
Description of drawings
Below the content of each width of cloth accompanying drawing expression of the utility model instructions and the mark among the figure are made brief description:
Fig. 1 is that the utility model detects and warning circuit figure automatically;
Mark among the above-mentioned figure is: 1, Switching Power Supply; 2, first relay; 3, second relay; 4, green light pilot lamp; 5, amber light pilot lamp; 6, red light pilot lamp; 7, alarm bell power supply.
Embodiment
Automatically detect and warning circuit figure referring to Fig. 1, this Circuits System mainly comprises PLC control module, relay, pilot lamp, Switching Power Supply 1, described PLC control module is powered by Switching Power Supply, the equipment that detects monitoring with need is connected, receive the status signal of its equipment, and drive the flicker of relay closure or openness control pilot lamp according to this signal.
These equipment that need detect monitoring are generally the main equipment with nature of danger, and it all can be divided into three phases from beginning to moving: beginning, and ready, operation.Therefore, we can be provided with three kinds of different states according to this three phases: pilot lamp is made as green light pilot lamp 4, amber light pilot lamp 5 and red light pilot lamp 6 respectively, by the pilot lamp flicker different according to the status signal control of equipment of PLC control module.Warn effect by force and effectively in order to reach, we have used 6 groups of pilot lamp groups to the pilot lamp of every kind of color, can increase according to actual needs or delete during use.
Also can add the alarm bell device simultaneously according to the size of danger in good time, be connected the keying of controlling outer tapper by PLC control module and alarm bell 7 modules of powering, so just can play warning function to people on every side from vision and the sense of hearing two aspects, and do not need the people for operating, directly the state according to equipment detects automatically.
Concrete controlled step is as follows:
In " beginning " state, after PLC detects the interlocking signal of " beginning ", first relay 2 and the 3 not adhesives of second relay, at this time the green indicating lamp 4 of the diverse location around the installation environment all begins flicker, and caution equipment is " beginning ".And then system equipment begins preliminary work (such as preheating, fault detect etc.), after being ready to complete " ready " interlocking signal is delivered to PLC, at this time PLC according to interlocking signal with 2 adhesives of first relay, green light pilot lamp 4 states transfer yellow indicator lamp 5 states to, and the yellow indicator lamp 5 that at this time is installed in environment all begins flicker, simultaneously alarm bell can be set and begin to sound, caution equipment is " ready ", please don't be close.Starting outfit after ready, the " RUN " interlocking signal is delivered to PLC, at this time PLC according to the " RUN " interlocking signal again with 3 adhesives of second relay, yellow indicator lamp 5 states transfer red led 6 states to, the red led 6 that at this time is installed in environment all begins flicker, simultaneously alarm bell can be set and sound, caution equipment is " RUN ", and danger please don't be close.
