Abstract

A multi-functional sensor socket, which belongs to electronic technological field and comprises a socket body, a photoelectric coupler set and a CPU, the socket body is connected with the CUP through photoelectric coupler set, the CPU makes encoding according to 8421 encoding principle and makes out corresponding encoding according to the type of the sensor. The encoding of the sensor conducts the photoelectric coupler when sensors are plug in the socket, the CPU generates corresponding encoding of the sensor to make the CPU know what kind the sensor is, and then read out data collected by the corresponding sensor from the T1 output terminal of the photoelectric coupler according to the type of the sensor. The utility model can automatically differentiate the type of the plug-in sensor and realizes the uniformity of the interface of under mine inspection devices, the installation is convenient, and can realize one-port-multi-use.

Description

A kind of Multifunction Sensor socket

Technical field:

The utility model belongs to electronic technology field, is a kind of sensor socket.

Background technology:

Mine underground work security requirement is very high, generally need monitor subsurface environment by multiple sensors, the existing sensors socket is single corresponding, specifically be that every kind of transducer will insert the socket ability operate as normal that is mated specially, as the essential methane gas sensor socket that inserts of methane gas sensor, insert normally image data of carbon dioxide gas sensor socket, therefore need install a lot of sockets in the underground work place, it is big to take up room, and need make an accurate selection of socket during operation and use inconvenience.

Summary of the invention:

The purpose of this utility model is that a kind of multi-function jack that can cooperate multiple sensors to use will be provided.

The scheme of the utility model technical solution problem is to adopt socket, photoelectrical coupler group and CPU constitute the Multifunction Sensor socket, socket connects CPU by the photoelectrical coupler group, wherein 1 of socket, 2,3 are connected the photoelectrical coupler T2 of photoelectrical coupler group respectively with 4 pin, T3, the input of T4 and T5,5 pin of socket connect the input of the photoelectrical coupler T1 of photoelectrical coupler group, photoelectrical coupler T2, T3, the output of T4 and T5 is connected the PB0 of CPU respectively, PB2, PB3 and four I/O mouths of PB4 line, the output of photoelectrical coupler T1 connects the PB1 I/O mouth line of CPU.CPU makes coding by 8421 coding principles, can make 14 kinds of corresponding encoded by the kind of transducer, and reserves a void type and a type of error coding.When transducer inserts socket, the coding conducting photoelectrical coupler of this kind transducer, because the output of photoelectrical coupler connects the I/O mouth line of CPU respectively, produce the coding of corresponding this transducer, it is the transducer of what type that CPU is known, reads the data of respective sensor collection then from the output of photoelectrical coupler T1 according to the kind of transducer.

The utility model can be differentiated the sensor type that is inserted automatically, realizes the uniformity of downhole monitoring equipment interface, and the convenience of installation realizes the many usefulness of a bite, and simple to operate, dependable performance is specially adapted to downhole safety production.

Description of drawings:

Accompanying drawing is the utility model electronic-circuit diagram.

Embodiment:
