Description
Technical field
This utility model relates to field of electrical control, is specifically related to a kind of Novel industrial B code coding/decoding module.
Background technology
When B code can be used for industry pair, by B code is counted, control the course of action of equipment.And most industry
B code only can be encoded by level enumerator, it is impossible to decoding, in use, only can carry out the timing of single, when the counting of enumerator
When value reaches maximum, it is impossible to auto zero, it is achieved circulation timing, the most also need additionally to prepare decoder and individually solve
Code, adds equipment cost.It is thus desirable to a kind of Novel industrial B code coding/decoding module solves the problems referred to above.
Utility model content
The purpose of this utility model is that provides a kind of Novel industrial B code encoding and decoding mould to solve the problems referred to above
Block.
This utility model is achieved through the following technical solutions above-mentioned purpose:

Equipped with described decoder, described decoder side is provided with symbol counter, and described symbol counter side is provided with diode,
Described diode side is provided with resistance.
In said structure, described clock counter is the enumerator of 20, and technology cycle is (2^20)/50M=21ms, when
Detect when rising edge occurs in B code, counting value returns, when count value meter to maximum, keep this maximum, until again going out
Existing rising edge, when count value meter to maximum, produces LOS alarm, and described warner sends warning signal, can be by described inspection
Survey chip and search failure problems, when B code rising edge being detected, according to the count value of described symbol counter, by described decoding
The data that device is judged put into described depositor, complete decoding, when described clock counter detects that described depositor updates mark
When will is high, described clock counter makes zero, when described symbol counter detects that the renewal of described depositor is masked as high, and institute
State symbol counter also to make zero, start to recompile.
In order to improve the use function of B code coding/decoding module further, described power supply is bolted on described pcb board
Part.
All pass through to improve the use function of B code coding/decoding module, described detection chip and described warner further
Draw-in groove is fixed on described pcb board part, and is fixed on described pcb board part by scolding tin.
In order to improve the use function of B code coding/decoding module further, described clock counter, described decoder and described
Symbol counter is all fixed on described pcb board part by draw-in groove, and is fixed on described pcb board part by scolding tin.
Scolding tin is all passed through in order to improve the use function of B code coding/decoding module, described diode and described resistance further
It is fixed on described pcb board part.
Have the beneficial effects that: B code can be counted, encodes and decodes, can realize circulating timing, reduce equipment purchasing
