Abstract
A plug-and-play sensor socket used in mine, which belongs to electronic technical field and comprises a socket body, a photoelectric coupler set, a CPU, and power source photoelectric coupler and a darlington circuit, the socket body is connected with the CPU through the photoelectric coupler set, the CPU is connected with the socket body through the power source photoelectric coupler and the darlington circuit, the CPU timely checks when a sensor is plug in from the outside when in work, a high voltage is output through the PD5 terminal of the CPU when sensor is detected to plug in to make the power source photoelectric coupler and the darlington circuit to conduct, the 6 foot of the socket body is delivered to the cathode of the power source of the external sensors to complete the power supply process of the sensor. A low voltage is output through the PD5 terminal of the CPU when no sensors plug in, the 6 foot of the socket body delivers no cathode of the power source, and the entire socket has no power source. The utility model is normally power-off and automatically supplies electricity when sensors plug in, thus can effectively avoid under mine blast led by spark caused by the plug-in of the sensors.
Description
Technical field:
The utility model belongs to electronic technology field, is a kind of sensor socket.
Background technology:
Generally all there are inflammable, explosion hazard gasess such as methane in the down-hole, mine, operational security requires very high, generally need monitor subsurface environment by multiple sensors, the existing sensors socket is the plain edition socket, and the essential socket power that turn-offs is connected socket power behind the insertion transducer again during operation, if charged insertion transducer, may produce spark, cause well shooting, cause a serious accident.
Summary of the invention:
The purpose of this utility model is that a kind of plug and play sensor socket that does not need power cutoff just can insert transducer will be provided.
The scheme of the utility model technical solution problem is to adopt socket, the photoelectrical coupler group, CPU, power supply photoelectrical coupler and Darlington circuit constitute the plug and play sensor socket, socket connects CPU by the photoelectrical coupler group, CPU is connected with socket by power supply photoelectrical coupler and Darlington circuit, wherein 1 of socket, 2,3 are connected the photoelectrical coupler S2 of photoelectrical coupler group respectively with 4 pin, S3, the input of S4 and S5,5 pin of socket connect the input of the photoelectrical coupler S1 of photoelectrical coupler group, photoelectrical coupler S2, S3, the output of S4 and S5 is connected the PB0 of CPU respectively, PB2, PB3 and four I/O mouths of PB4 line, the output of photoelectrical coupler S1 connects the PB1 I/O mouth line of CPU, the PD5 mouth line of CPU connects the input of power supply photoelectrical coupler S6, Darlington circuit is made of triode T1 and T2, the output of power supply photoelectrical coupler S6 connects Darlington circuit triode T2 base stage, 6 pin of the collector electrode gang socket body of triode T1 and T2,7 pin of socket connect the anode of power supply by diode D1.During work, when detecting the outside by the photoelectrical coupler group in good time, the PB of CPU mouth whether have transducer to insert, when the transducer insertion is detected, PD5 mouth output high level by CPU, make the conducting of power supply photoelectrical coupler, conducting Darlington circuit conducting again, the power supply negative terminal of transducer is delivered on the power cathode of external sensor by socket 6 pin via Darlington transistor like this, power positive end patches pedestal 7 pin through diode D1 simultaneously, finishes the power supply process of transducer.When not having transducer to insert; CPU recognizes and is void type; the PD5 mouth output low level of CPU; the power supply photoelectrical coupler is in cut-off state, thereby the triode T1 and the T2 of Darlington circuit end, though this moment, socket 7 pin connect power positive end; but because socket 6 pin do not have power supply negative terminal to send; be in off-position,, play a protective role so do not have power supply on the whole socket.
The utility model cuts off the power supply at ordinary times, and automatic power after inserting transducer can effectively be avoided producing the well shooting that gunpowder causes because of inserting transducer, and simple to operate, dependable performance is specially adapted to downhole safety production.
