The element of system, is defined as common components.
Further, each segmentation includes the common components being connected thereto and at least one block switch element.
Further, the bus protection of the identical complete set of each segmented configuration, and by independent logic CPU Lai real
It is existing.
Further, each logic CPU outputs channel there are one signal, for being driven after this section of bus protection acts
It is connected to the failure tripping of the block switch element on this section of busbar.
Further, each logic CPU has several signals to open to access the letter that the signal outputs channel into channel
Number, the block switch for being drivingly connected to by this section of bus protection after other sections of bus protections act on other sections of busbares
Unsuccessful reason；It is equal with the block switch number of elements that this section of busbar is connected that signal opens the quantity into channel.
The direct information interaction approach of logic CPU includes：One, the signal of all logic CPU is opened to be outputed into channel and signal
Channel is all connected on public data/address bus, to realize the information exchange between Different Logic CPU.Two, each two logic
Establish point-to-point data pipe between CPU, receive that other side CPU sends opens signal into channel transfer via signal, and
The signal transmission that signal is outputed to channel gives other side CPU.
The purpose of the present invention is to propose to a kind of complicated wiring median generatrix guard method suitable for micro-capacitance sensor, core is female
The structure of line protection, by bus section, each segmentation is using the Preservation tactics set, to reduce micro-capacitance sensor bus protection version
This, simplifies the complexity of bus protection design, reliable bus protection can be further provided for micro-capacitance sensor, ensures micro- electricity
The safe and stable operation of net.
Description of the drawings
Fig. 1 be the method for the present invention one embodiment in certain micro-capacitance sensor complicated wiring busbar wiring patterns schematic diagram.
Fig. 2 is the schematic diagram that more logic CPU carry out that data are mutually passed by data/address bus.
Fig. 3 is the schematic diagram that more logic CPU carry out that data are mutually passed by Point-to-Point Data pipeline.
Specific implementation mode
The present invention will be further described in detail below in conjunction with the accompanying drawings.
In Fig. 1, K1~K12 elements connect into a micro-grid system, and bus rod is the pass that energy collects and exchanges
Button apparatus.First distinguish usual connection members and block switch element.K1, K2, K3, K5, K6, K9, K10, K11 and K12 element
It is connected respectively to micro battery, load or energy-storage system, is considered as usual connection members；K4 has bridged two sections of I and II sections of bus rods,
K7 has bridged two sections of I and III sections of bus rods, and K8 has bridged two sections of II and III sections of bus rods, therefore K4, K7 and K8 are considered as
Block switch element.
Using K4, K7 and K8 as boundary, the bus rod of micro-capacitance sensor is divided into three parts.By K1, K2, K3, K4 and K7 element
Constitute the protection of I sections of bus rod；The protection of II sections of bus rod is made of K4, K5, K6 and K8 element；By K7, K8, K9,
K10, K11 and K12 element constitute the protection of III sections of bus rod.
The defencive function that I sections of bus rod is completed by logic CPU1, and the defencive function that II sections of bus rod is by logic CPU2
It completes, the defencive function that III sections of bus rod is completed by logic CPU3.The defencive function complete one that these three logics CPU is realized
It causes, is only that the element number of access differs.As block switch element, K4 elements have accessed bus rod I and II by K4, K7 and K8
The protection of section, K7 elements have accessed the protection of I and III sections of bus rod, and K8 elements have accessed the guarantor of II and III sections of bus rod
Shield.
Logic CPU1 has accessed block switch K4 and K7, therefore logic CPU1 is opened there are two signal into channel, respectively " phase
Adjacent busbar trip starts the block switch failure of label K4 " and " adjacent busbar trip, the block switch for starting label K7 lose
Spirit ".Similar with this, there are two signals to open into channel by logic CPU2, the block switch failure of corresponding K4 and K8；Logic CPU3 has two
A signal is opened into channel, the block switch failure of corresponding K7 and K8.Three logic CPU have 1 signal to output channel, for driving
Move the failure tripping for the block switch that this section of bus rod is connected.
Above listed signal opens channel and signal is outputed channel and is all connected on data/address bus, as shown in Figure 2.Or
Using following 6) described modes.
Data pipe is established between logic CPU1, logic CPU2 and logic CPU3.Data pipe transmission content and mutually
