Description
Technical field
The utility model belongs to aircraft distribution technique, particularly relates to the two remaining control circuit of a kind of solid state distribution rating of set passage.
Background technology
Solid state distribution device is a kind of power distribution equipment based on solid state distribution technology and computer generalization control technology, realizes the intelligent management of distribution system by detecting more power distribution system information.Solid state distribution device forms primarily of CPU module, Signal-regulated kinase and multiple power channels.
In order to alleviate aircraft distribution system cable weight, usually by bus, the multiple power channels in solid state distribution device are controlled.This is a kind of single remaining control mode, and reliability is lower.When the CPU module in solid state distribution device or bus malfunctions, the power channels in solid state distribution device can be caused uncontrollable, cause the load that aircraft electric system is corresponding uncontrollable, serious threat may be caused safely to aircraft.
Utility model content
The purpose of this utility model is: provide one not need to change internal circuit design, arbitrary for solid state distribution device power channels can be configured to two remaining control circuits that user needs.
The technical solution of the utility model is: the two remaining control circuit of a kind of solid state distribution rating of set passage, is characterized in that: solid state distribution device each power channels inner arranges two-way rigid line control signal; Solid state distribution device each power channels inner arranges a logical device; Described logical device is connected with microcontroller by the wire on printed circuit board; Microcontroller is connected with CPU module by internal bus; CPU module is connected with external bus by bus interface; Logical device is connected with hard signal conditioning module by the wire on printed circuit board; Logical device is connected with current detection module by the wire on printed circuit board; Logical device is connected with the driving circuit of power switch by the wire on printed circuit board; Driving circuit is connected with power switch by the wire on printed circuit board.
Compared with prior art, the utility model has the advantages that: (1) solid state distribution device, according to the two remaining control circuit of this Model Design power channels, can avoid user's request to change causing equipment to do over again the human and material resources that cause and time waste; (2) solid state distribution rating of set channel control can be configured to the one in three kinds of common pair of remaining control modes as required by user, and the reliability of plant capacity passage and versatility strengthen.
Accompanying drawing explanation
Fig. 1 is the two remaining control circuit principle schematic of solid state distribution rating of set passage of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
See Fig. 1.The two remaining control circuit of a kind of solid state distribution rating of set passage, solid state distribution device each power channels inner arranges two-way rigid line control signal, one road rigid line control signal is used for power channels and opens control, and a road rigid line control signal is used for rigid line and turns off control; Solid state distribution device each power channels inner arranges a logical device; Device described in logic is connected with microcontroller by the wire on printed circuit board; Microcontroller is connected with CPU module by internal bus; CPU module is connected with external bus by bus interface; Logical device is connected with hard signal conditioning module by the wire on printed circuit board; Logical device is connected with current detection module by the wire on printed circuit board; Logical device is connected with the driving circuit of power switch by the wire on printed circuit board; Driving circuit is connected with power switch by the wire on printed circuit board.The input signal of logical device comprises to be opened control signal B, the road rigid line after Signal-regulated kinase process turn off control signal C and the short-circuit protection signal D of a road after current detection module process from the bus control signal A of external bus after microcontroller process, the rigid line of a road after Signal-regulated kinase process; The output signal of logical device is as the input signal Y of power switch drive module; The output signal of logical device and the pass of input signal are:
the constraint condition of this expression formula is: BC=0.Namely rigid line open control signal and rigid line turn off control signal different time effective.
Power channels control command is delivered to the CPU module of solid state distribution device by external bus, and the power channels control command received is passed to the microcontroller of power channels by CPU module by internal bus.The power channels bus control commands A processed is passed to logical device by microcontroller.
The current signal flowing through power switch is converted to the short-circuit protection signal D of programmable logic device (PLD) needs by current detection module according to arranging.
Signal-regulated kinase conditioned rigid line is opened control signal B and rigid line shutoff control signal C is delivered to logical device.
Logical device is according to formula
to bus control commands A, control signal B opened by rigid line, rigid line turns off control signal C and short-circuit protection signal D process, and the on/off signal of output power switch is to driver module.Driver module processes this signal and controls the on/off of power switch.
Now, each power channels of solid state distribution device all can be configured to following four kinds of patterns:
(1) when passage is as when only using bus to control, in solid state distribution device outside, rigid line is opened control signal B and rigid line shutoff control signal C ground connection, steering logic is become
.
(2) when passage as bus add rigid line open pattern use time, solid state distribution device outside rigid line is turned off control signal C ground connection, steering logic is become
.
(3) when passage adds the use of rigid line shutdown mode as bus, in solid state distribution device outside, rigid line is opened control signal B ground connection, steering logic is become
.
(4) when passage add that rigid line is opened as bus, rigid line shutdown mode use time, do not need to carry out any outer setting.
