Description
Technical field
The utility model relates to a kind of robotization protection system that is used on the power supply of geological data work of treatment station.
Background technology
Geological data work of treatment station is a kind of computer equipment of important costliness, and along with after computing machine is widely used in the earthquake data processing system, the abnormal conditions of this system power supply are detected has just become a crucial job.Existing power detector is for geological data work of treatment station; It is too careless to detect; Generally all be that just can detect when unusual on a large scale appears in power supply; Like this, just be very easy to cause the corrupted data in the geological data work of treatment station, thereby cause huge direct economic loss and immeasurable indirect loss.
Summary of the invention
In order to solve the prior art problem that background technology proposes; The utility model provides a kind of novel abnormity of power supply warning circuit that is used on the power supply of geological data work of treatment station; This kind warning circuit; Can effectively protect geological data work of treatment station power supply, be convenient to the technician and when power fail is very slight, find also on-call maintenance, thereby avoid lossing of geological data.
The technical scheme of the utility model is: this kind is used for the abnormity of power supply warning circuit on the power supply of geological data work of treatment station; Comprise positive-negative power acquired signal input end and the alarm signal output ends of 2 12V, its unique distinction is: between said positive-negative power acquired signal input end and alarm signal output ends, being connected with reference voltage in turn according to the circuit concatenate rule provides circuit, voltage ratio than testing circuit and 2 groups of optocouplers; Wherein, said reference voltage provides circuit to adopt the U100/LM317 chip, and said voltage ratio adopts the U300/LM393N chip than testing circuit; Said reference voltage forms 2 links after providing the output terminal of circuit to pass through the divider resistance dividing potential drop, is connected to said voltage ratio No. 2 pins and No. 5 pins than testing circuit respectively; Voltage ratio is connected to the coupled signal input end of 2 groups of optocouplers respectively than No. 1 pin of testing circuit and No. 7 pins; The coupled signal output terminal of said 2 groups of optocouplers is as alarm signal output ends.
The utlity model has following beneficial effect: this kind is used for the abnormity of power supply warning circuit on the power supply of geological data work of treatment station, is operated in the Low-voltage Low-power state, so working stability is safe and reliable.Though solved the power supply of each quasi-instrument thus multiple safety practice is arranged, because of it is operated in the high-voltage great-current state, in case damage; The problem that other safety practice all lost efficacy; Therefore this kind circuit is installed on after geological data work of treatment station goes up, and can monitor multiclass direct supply voltage as required, and solving geological data work of treatment station supply voltage transfinites and damage other circuit elements device and the supply voltage power supply problem of damage fast that transfinites; And then the protection significant data, in order to avoid lose.In addition, utilize this kind abnormity of power supply warning circuit after, do not need to set up power supply in addition, but adopt the power supply of machine to be checked, very convenient.In addition, for the reliability of intensifier circuit, this abnormal alarm circuit employing+12V-1 and+12V-2 supply power simultaneously; As long as+12V-1 and+12V-2 have one normal, but this abnormal alarm circuit operate as normal just can be monitored the duty of power supply at any time; And power supply beyond circuit whether transship, prevent trouble before it happens, can effectively protect power supply; Be convenient to the technician and when power fail is very slight, find, and on-call maintenance.
Description of drawings:
Fig. 1 is the electrical schematic diagram of the utility model.
The U1-reference voltage provides circuit among the figure, and the U2-voltage ratio is than testing circuit, the 1st group of optocoupler of U3-, the 2nd group of optocoupler of U4-.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1; This kind of composition that is used for the abnormity of power supply warning circuit on the power supply of geological data work of treatment station is as shown in Figure 1; The positive-negative power acquired signal input end and the alarm signal output ends that comprise 2 12V, between said positive-negative power acquired signal input end and alarm signal output ends, being connected with reference voltage in turn according to the circuit concatenate rule provides circuit U 1, voltage ratio than testing circuit U2 and 2 groups of optocoupler U3, U4; Wherein, said reference voltage provides circuit to adopt the U100/LM317 chip, and said voltage ratio adopts the U300/LM393N chip than testing circuit; Said reference voltage forms 2 links after providing the output terminal of circuit U 1 to pass through the divider resistance dividing potential drop, is connected to said voltage ratio No. 2 pins and No. 5 pins than testing circuit U2 respectively; Voltage ratio is connected to the coupled signal input end of 2 groups of optocoupler U3, U4 respectively than No. 1 pin of testing circuit U2 and No. 7 pins; The coupled signal output terminal of said 2 groups of optocoupler U3, U4 is as alarm signal output ends.
Through its power port, deliver to 3 pin and 6 pin of U300/LM393 by the voltage to be measured of+12V-1 end input, U300 is a voltage comparator; When the voltage of 3,6 pin is between 2 pin voltages and 5 pin voltages, this circuit is made as ± and 3%; Be between the 11.64V to 12.36V the time, luminous 2 utmost point pipe conductings among optocoupler U3 and the U4, photosensitive 3 utmost point pipe conductings among U3 and the U4; Photosensitive 3 utmost point pipe C among U3 and the U4 are low level very; The external IN40001 diode of the coupled signal output terminal of optocoupler U3, U4 ends, thus sound light alarming circuit and relay K do not work, at this moment just show+voltage of 12V-1 input is in allowed band.Otherwise, if the voltage of 3,6 pin is not between 2 pin voltages and 5 pin voltages; Promptly+and 12V-1 voltage deviation standard value transfinites, optocoupler U3 then, and U4 must have one of them to end; As long as U3, U4 has any one to end, and 3 utmost point pipe C of the optocoupler that then ends are high level very; Make the diode 1N4001 conducting that links to each other with the optocoupler that ends, thereby make sound light alarming circuit and relay work after the warning circuit conducting, at this moment show+voltage of 12V-1V end input transfinites.
