Figure 11 is electrical equipment measurement and control bus and electrical equipment observing and controlling assembly embodiment 1.The electrical equipment measurement and control bus is by a power delivery bus, and a bi-directional data transfer bus and a grounding jumper are formed.The observing and controlling assembly by monolithic compile, decoding scheme, the state storage circuit, power electronic switching, state detection circuit is formed.State detection circuit is by the car light testing circuit, the brake facing testing circuit, and the meeting testing circuit, the load carrying ability testing circuit is formed.Articulated two electrical equipment observing and controlling of forward and backward car light assembly among the figure on the bus,, also can articulate the electrical equipment observing and controlling assembly of any amount on the bus as circuit operation.
Among the figure, IC9, IC10 is respectively volume, the decoding scheme of forward and backward car light electrical equipment observing and controlling assembly, IC11, IC12 are respectively the state storage circuits of forward and backward observing and controlling assembly, IC2～IC9 is respectively the power electronic switching of control front car light and loudspeaker, and IC14～IC21 is the power electronic switching of control back car light.R1～R6 constitutes the front car light testing circuit, and R11～R17 constitutes back car light testing circuit, and L1 is the brake facing testing circuit, and P1, P2, IC13, D3 constitute the meeting testing circuit, and P1 is the load carrying ability testing circuit.IC9, IC10 have eight bit address sign indicating number ends, and the monolithic of eight bit data sign indicating number end is compiled, decoding scheme, often are in the decoding state of received signal at ordinary times.A0～A7 is its geocoding end.As can be seen from the figure forward and backward car light electrical equipment observing and controlling assembly has different separately address codes.D0～D7 is its data output end, and data coding input end links with input of state storage circuit and state detection circuit output.Output Q0～the Q7 of state storage circuit links to each other with the control end of each power electronic switching.Taking front car light electrical equipment observing and controlling assembly is that example illustrates its principle of work.When receiving microcomputer, IC9 transmits from bi-directional data transfer bus, behind the control signal identical with this decoder address, and just with this signal latch, and by mouth D0～D7 output, DV end output one high level decoding received signal simultaneously; This signal one tunnel is through C5, the differential circuit that R24 forms forms on the storage control end LE that a positive pulse signal is added to state storage circuit IC11, IC9D0～D7 state output terminal is sent into the IC11 storage, this signal is through Q0～Q7 output, the power controlling electronic switch, make cooresponding car light or loudspeaker switching, finish concrete control.Another road of high level signal of DV end is via R10, and the integrating circuit that C1 forms is added on the TR end of IC9, and the TR end is that IC9 compiles, decoding mode control end.TR termination low level, IC9 is in the decoding state, otherwise then is in encoding state.Because be in low level state when DV holds level with both hands always, the TR end also is in low level state always, after the DV end becomes high level state, through R10, C1 is after time-delay a period of time, and the TR end is in high level state, and IC9 becomes coding and sends mode of operation, the state of detected each electrical equipment of state detection circuit is added in D0～D7 end, oppositely sends microcomputer by A0 output to by bi-directional data transfer bus behind the IC9 coding.After IC9 became encoding state, the DV end became low level, and C1 discharges through R10, and through after a while, the TR end becomes low level, and IC9 is in the decoding receiving condition again.Finish a reception, send the working cycle of signal.The working process of other road electrical equipment observing and controlling assembly also fully so.
The common feature of state detection circuit is, when the working condition of institute's detection electrical equipment changes or the driving parameter that detected when being higher or lower than certain critical value, height takes place its outgoing level changes.This variable signal is given microcomputer by the bi-directional data transfer bus reverse transfer after crossing encoded circuit code.With car light LA1, the working process of resistance R 1 for example explanation car light testing circuit detected on this road.When this road power electronic switching was in closed condition, power supply was through R1, and car light LA1 filament resistance constitutes a loop with ground.The filament resistance of LA1 is very little, the resistance of R1 be designed so that loop stream cross μ A level weak current and when car light LA1 filament intact, power supply is the low level voltage value of IC9 through the voltage that is added on the LA1 after the R1 dividing potential drop.Close so work as IC2, when LA1 was in serviceable condition again, the signal that this alignment detection circuit feeds back to microcomputer was a low level signal.If the wire break or the bad contact of LA1 filament open circuit or connection car light, when being in the state of cisco unity malfunction, state detection circuit feeds back to the high level signal that is of microcomputer.Utilize this low, High variation of outgoing level, microcomputer just can judge whether car light is intact.When system controlled by computer IC2 was in conducting state, power supply directly was added on the LA1 without R1, and feed back to the high level signal that should be of microcomputer this moment, if low level signal illustrates that then power electronic switching damages.Because microcomputer is the signal that fed back of acquisition testing circuit constantly at any time, thereby can judge the working condition of car light and power electronic switching.If et out of order can be distinguished the car light or the fault of electronic switch, adopt light and voice suggestion alarm.The working process of the car light testing circuit on other road is identical.
L1, R7 forms the brake facing testing circuit.L1 is that one section coil or lead embed in the brake facing.When brake facing not may wear to the limit of permission, L1 was intact, and by C7 output is high level signal, if brake facing may wear to limit, this moment, L1 was rubbed, by C7 output be low level signal, this signal is added in the numeric data code end coding of coder IC9 and exports to microcomputer.
Photosensitive tube P1, P2, Exclusive-OR gate (XOR gate) IC13, R23 forms the nighttime meeting testing circuit.P1 is installed in the car front portion, and P2 is installed in the car sidepiece.The P1 that drives a vehicle is subjected to the direct projection of the other side's car light when night, P2 is shone, at this moment, the P1 conducting, P2 still is in the blocking-up attitude, be added in IC131, the level state difference of 2 input ends is by C8 output high level signal, when driving a vehicle no meeting or day driving night, the state of IC13 input end is identical, C8 output low level signal.C8 output also is added in the data input pin of IC9.
P1 load carrying ability testing circuit is by pressure sensor, amplifier, and comparator circuit is formed.Be installed in can the position of sense vehicle load-carrying situation on.Load carrying ability is transformed into electric signal by pressure sensor, after amplifier amplifies, is added in the input end of comparator circuit.The other end then adds comparative voltage, and the size of comparative voltage is then represented the Maximum Loading Capacity of permission, and when the voltage of signal input part was higher than comparative voltage, by B8 output high level, the expression load carrying ability transfinited, on the contrary output low level then.
Figure 12 is electrical equipment measurement and control bus and electrical equipment observing and controlling assembly embodiment 2.Measurement and control bus by one by the power delivery bus, two bi-directional transfer of data lines and a grounding jumper are formed.The observing and controlling assembly is then by encode circuit, decoding scheme, and power electronic switching, state detection circuit is formed.This circuit compares with figure 11, just use encode circuit, decoding scheme replaces monolithic volume, decoding scheme IC9, IC10 and the state storage circuit IC11 of figure 11, IC12, bi-directional data transfer bus is increased to two by one, the composition of other parts circuit, the related circuit of symbol and effect and figure 11 is identical.
In figure 12, IC29, IC27, IC22, IC24 have five bit address coding sides, and four figures is served as the coding task of two electrical equipment observing and controlling of front and back car light assembly respectively according to the coding integrated circuit of coding side.IC28, IC26, IC23, IC25 have five bit address sign indicating number ends, and four figures is served as the decoding task of two electrical equipment observing and controlling of forward and backward car light assembly respectively according to the decoder ic of sign indicating number end.Each coding, decoding scheme all have geocoding inequality separately.IC2～IC9, IC14～IC21 are respectively the power electronic switchings of forward and backward car light electrical equipment observing and controlling assembly.R1～R6 constitutes the front car light testing circuit, and R11～R17 constitutes back car light testing circuit.L1, R7 constitutes the brake facing testing circuit, and P1, P2, IC13 constitute the meeting testing circuit.P1 is the load carrying ability testing circuit.Just the same described in the principle of work of each testing circuit and the figure 11.Because volume, decoding scheme among this figure have only four figures to hold according to sign indicating number, be a control group so eight car lights that front and back car light observing and controlling assembly is controlled or electrical equipment are divided into per four, be divided into into four groups.Every group of control, four electrical equipment of measurement and parameter.
With IC29, one group of the IC28 composition is that example illustrates its working process.IC28 is a decoding scheme, and own specific address is arranged, and is in the decoding receiving condition once powering on, and IC29 is an encode circuit, and the particular address of oneself is also arranged, and the overwhelming majority time is in the non-coding transmit status of little power consumption.IC28 is not when receiving with code signal that this address conforms to, and data output end D0～D3 keeps original state.This moment, the VT end was a low level, was added in after VT signal bits T1 is anti-phase on the coding control end TE of IC29, made IC29 be in the non-encoding state of little power consumption.When IC28 received the control signal that microcomputer is that transmit through bi-directional data transfer bus 2 with this address conforms to, control data was held output by D0～D3, and power controlling electronic switch IC2～IC5 makes corresponding electrical equipment switching.Simultaneously, VT end output one high level signal becomes the TE end that low level is added in IC29 after T1 is anti-phase, make it be in the coding transmit status, be added on coded data input end D0～D3, the signal of state detection circuit C1～C4 end output, after data output end DO exports, oppositely send microcomputer to through the IC29 coding through bi-directional data transfer bus 1.The working process of other group also is like this.IC29, IC27, IC22, the data output end D0 of IC24 links together, and is connected on the bi-directional data transfer bus 1.IC28, IC26, IC25, the data input pin DI of IC23 links together, be connected on the bi-directional data transfer bus 2, microcomputer transmits control signal to each group according to the order of stipulating one by one by bi-directional data transfer bus 2, is received by bi-directional data transfer bus 1 then and respectively organizes electrical equipment and other status signal that testing circuit is sent here.
