Description

Coding method for preventing connector plugging errors

Technical field

The present invention relates to a kind of coding method, specifically, relate to a kind of coding method for preventing connector plugging errors.

Background technology

Microcomputer detecting system is in the process used, and the kind of the signal that monitored equipment produces or range are not quite similar, and need use different collection plates for different collection signals, and this just causes the various of collection plate kind.Because the signal that different acquisition plate gathers is different, on bus board, collection plate cisco unity malfunction can be caused in wrong plug position, even damages collection plate.

In order to solve above Problems existing, people are seeking a kind of desirable technical solution always.

Summary of the invention

The object of the invention is for the deficiencies in the prior art, thus provide a kind of coding method for preventing connector plugging errors, the method effectively can avoid collection plate wrong plug position in bus.

To achieve these goals, the technical solution adopted in the present invention is: a kind of coding method for preventing connector plugging errors, and it adopts segment encoding method, comprises the following steps:

Step 1, respectively a code bit for 11 on plug and socket coding is divided into three sections, wherein, first paragraph has 2N position to encode, be used for distinguishing the type of collection plate, second segment has 2N position to encode, and is used for distinguishing the classification number in same function, 3rd section is a remaining coding, as reservation process;

Step 2, respectively by the 2N position of first paragraph on plug coding and second segment 2N position coding by the arrangement that puts in order, wherein, N position coding in the 2N position coding of the first paragraph on plug to be encoded radix-minus-one complement each other with remaining N position, encodes radix-minus-one complement each other in the N position coding in the 2N position coding of second segment and remaining N position;

Is encoded by the arrangement that puts in order in the 2N position of the 2N position of first paragraph on socket coding and second segment respectively, wherein, N position coding in the 2N position coding of the first paragraph on socket to be encoded radix-minus-one complement each other with remaining N position, encodes radix-minus-one complement each other in the N position coding in the 2N position coding of second segment and remaining N position;

Step 3, when the coding on plug and socket each other radix-minus-one complement time, then plug and socket supporting, otherwise, then plug and socket non-supporting;

Wherein, N be not less than 1 natural number.

Hinge structure of the present invention has outstanding substantive distinguishing features and marked improvement, and specifically, the present invention adopts segment encoding method, and classification is clear and definite; Adopt the connector of the method, only have the coding when the terminal of collection plate to refer to and bus board one_to_one corresponding, can carry out grafting, reach the object of Anti-misplug, it has the simple and practical advantage of method.

Embodiment

Below by embodiment, technical scheme of the present invention is described in further detail.

In order to avoid the position of wrong plug collection plate, the connector that have employed band Anti-misplug coding between collection plate with bus board is connected, wherein, collection plate is plug, and bus board is socket, respectively with 11 notches on plug and socket, every notch can be installed a coding and refer to, in 11 notches of plug and socket, as long as there is 1 to have coding to refer to, then plug can not insert socket.

Connector has 11 bits of coded, if according to Unified coding scheme, it is huge that the quantity of coding will become very, but also effectively can not avoid dissimilar plug and socket interfix.With 0 representative, coding is not installed to refer to, refer to illustrate with 1 representative installation coding: if bus board socket is encoded to 00000111111, as long as then low 6 of collection plate plug is encoded to 0, just can be inserted in this bus board position, that is, if use Unified coding scheme, multiple collection plate will be had and can be inserted in this socket position, not meet the requirement of Anti-misplug.

In order to avoid there is the phenomenon of wrong plug, in the operational version of reality, have employed following encoding scheme: the code bit called after abcdefghijk in order of 11 codings of plug and socket; Respectively a code bit for 11 on plug and socket coding is divided into three sections, wherein, (a-f) is one section, and be used for distinguishing the type of collection plate, (h-k) is one section, is used for distinguishing the classification number in same function, and remaining g then makes reservation process; Respectively 4 of 6 of (a-f) section on plug and socket codings and (h-k) section are encoded by the arrangement that puts in order, wherein, 3 codings in 6 codings of (a-f) section on plug and socket and remaining 3 radix-minus-one complements each other of encoding, 2 codings in 4 codings of (h-k) section and remaining 2 radix-minus-one complements each other of encoding.According to this method, as shown in Table 1 and Table 2, wherein, (a-f) section has 20 kinds of coded systems, and (h-k) section has 6 kinds of coded systems for available plug coding, socket coding.
