Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of reasonable in design, utilization ratio height and be convenient to system connect the supply unit based on electro-hydraulic control system.
The present invention solves existing technical problem and takes following technical scheme to realize:
A kind of supply unit based on electro-hydraulic control system, comprise power supply transfer unit, power step-up unit, Power convert unit, signal isolation unit, state indication unit and two groups of power output interfaces, power supply transfer unit, power step-up unit, Power convert unit is connected successively, the power output end of this electric power switching device is connected with next supply unit, described Power convert unit exports two groups of power supplys and is connected to two groups of power output interfaces respectively, this Power convert unit is also isolated unit by two-way power supply output line and signal respectively and is connected, this signal isolation unit is connected with two groups of power output interfaces respectively by system communications line, it is its power supply that two groups of power output interfaces are connected on two pack support controllers respectively.
And, the described signal isolation unit working order for supply unit that is also connected with state indicating device shows.
Advantage and the positively effect of the present invention be:
1, this supply unit adopts single group two-way intrinsic safety electric source to export, and promotes the quantity often organizing powered stent controller, decreases the usage quantity of supply unit.
2, this supply unit employing signal isolation unit, decreases the usage quantity of isolating coupler in system, solves the signal electrical isolation between different support controller group, simplifies assembling technique, only needs two cables, can complete to power between two pack supports and communicate.

Power step-up unit provides specified input voltage for promoting input voltage for Power convert unit, improve due to electrical network voltage and voltage drop problem along the line, solve long distance problem of pressure drop when electrical network voltage along the line is in lower limit, make whole bar go up each Power convert unit along the line and obtain specified input voltage, make supply unit efficiency of conversion be in optimum regime.
Power convert unit adopts single group to supply power with double circuit mode; often group output A/B two-way intrinsic safety electric source is powered to bracket controller; the relative single channel of load capacity is powered and is promoted one times; achieve the conversion of power of alterating and direct current and single group two-way intrinsically safe power supply output function, there are two level power supply output protections.
Signal isolation unit only needs two cables (system communications line) the communication signal between two pack supports can be carried out electrical isolation, it is achieved the electrical isolation function of system communication.
State indication unit adopts photodiode to carry out state display, it is achieved that the lamplight pointing function of each road power work state and isolation unit communications status.
It is emphasized that; embodiment of the present invention is explanation property; instead of it is limited; therefore the present invention comprises the embodiment being not limited to described in embodiment; every other enforcement modes drawn according to the technical scheme of the present invention by those skilled in the art, belong to the scope of protection of the invention equally.
