Background technology
The lightning protection circuit of ARINC429 bus signals, from being not used, lacks correlation in circuit design before
Safeguard procedures.
The content of the invention
It is an object of the invention to provide a kind of lightning protection circuit of ARINC429 buses, the protective of circuit is improved
Energy.
The lightning protection circuit of ARINC429 buses of the invention, between bus and back-end circuit, bus A ends and
Bus B end is connected with the two poles of the earth of gas-discharge tube respectively, the common end grounding of the gas-discharge tube；Bus A ends and bus B end point
One end not with respective resistance or inductance is connected, the other end and the two-way Transient Suppression Diode I of two resistance or inductance
The two poles of the earth connect；Bus A ends and bus B end by after the respective resistance or inductance, respectively with two-way Transient Suppression Diode
II and the pole connection of two-way Transient Suppression Diode III, two-way Transient Suppression Diode II and two-way Transient Suppression Diode III
Another pole ground connection.
Further, under normal condition, at the gas-discharge tube and each Transient Suppression Diode in lightning protection circuit
In high impedance status；When thunder and lightning indirect effect is subjected to, the gas discharge that transient energy is passed through the first order by lightning protection circuit
The two-way Transient Suppression Diode I of pipe and the second level carries out releasing for transient energy, and by voltage clamp a magnitude of voltage from
And ensure the safety of late-class circuit.
Further, when transient high voltages occur in bus A ends or bus B end, the two-way transient state of the 3rd pole suppresses two poles
Pipe II or two-way Transient Suppression Diode III absorb high current, by voltage clamp at one numerically, it is ensured that circuit below is exempted from
Damaged by the impact of transient energy, played a protective role.
Primary protection is carried out using gas-discharge tube in two inputs of ARINC429 bus signals, in bus signals
Between each input and two inputs two grades of protection, each input primary protection are carried out using two-way Transient Suppression Diode
The less inductance of value or resistance are used between two grades of protection.
Lightning protection circuit of the invention is to ensure that ARINC429 bus signals can be used normally in normal state, and
The big energy of transient state is realized that transient energy is let out by gas-discharge tube and Transient Suppression Diode when thunder and lightning indirect effect is subjected to
Put and clamp in certain magnitude of voltage, can be used safely with the normal and late-class circuit for ensureing signal, play a protective role, must
The smaller gas-discharge tube of parasitic capacitance and Transient Suppression Diode must be chosen.
Beneficial effect：ARINC429 bus lightning protection circuits can be applied to the control with bus signals lightning protection requirement
In system processed, circuit is simple, good stability, economy are high.
Brief description of the drawings
Fig. 1 is the input discrete magnitude BIT circuit block diagrams of lightning protection circuit of the present invention.
Specific embodiment
As shown in figure 1, gas-discharge tube and Transient Suppression Diode are in high impedance status in circuit under normal condition, when
When being subjected to thunder and lightning indirect effect, transient energy is put by first order protection circuit gas in the case where normal signal is not influenceed
Fulgurite and second level protection circuit Transient Suppression Diode carry out the releasing and by voltage clamp in a magnitude of voltage of transient energy,
So as to ensure the safety of late-class circuit.
The lightning protection circuit of ARINC429 buses, between bus and back-end circuit, bus A ends and bus B end
It is connected with the two poles of the earth of gas-discharge tube respectively, the common end grounding of the gas-discharge tube；Bus A ends and bus B end respectively with respectively
From resistance or inductance one end connection, the other end of two resistance or inductance and the two poles of the earth of two-way Transient Suppression Diode I connect
Connect；Bus A ends and bus B end by after the respective resistance or inductance, respectively with two-way Transient Suppression Diode II and double
Connected to a pole of Transient Suppression Diode III, two-way Transient Suppression Diode II and two-way Transient Suppression Diode III it is another
Pole is grounded.
Under normal condition, gas-discharge tube and each Transient Suppression Diode in lightning protection circuit are in high impedance shape
State；When thunder and lightning indirect effect is subjected to, gas-discharge tube and the second level of the lightning protection circuit by transient energy by the first order
Two-way Transient Suppression Diode I carry out releasing for transient energy, and by voltage clamp in a magnitude of voltage so as to ensure rear class
The safety of circuit.
When there are transient high voltages in bus A ends or bus B end, the two-way Transient Suppression Diode II or two-way of the 3rd pole
Transient Suppression Diode III absorb high current, by voltage clamp at one numerically, it is ensured that circuit below is from transient energy
Impact and damage, play a protective role.
When the transient state high-energy that thunder and lightning indirect effect is produced senses the A ends and B ends of bus signals, at this moment first order protection
Circuit gas-discharge tube punctures its internal inert gas by transient high voltages signal, and low resistance state is converted to by transient state energy by high-impedance state
Amount is conducted to ground, and portion of energy is released, and by big voltage clamp in a relatively low state, at this moment voltage is more than transient state
Suppress the voltage that starts to control of diode, second level protection circuit Transient Suppression Diode is started working, and low resistance state is presented, while absorbing
High current, by voltage clamp at one numerically, it is ensured that circuit below is damaged from the impact of transient energy, plays protection
Effect.
