If monitoring, the control signal of main control chip U1 output violates preset operation rule, be carried out corresponding processing movement (under
Text illustrates).
This intelligent digital power supply can be by network implementations to the online liter of the computer program of control main control chip U1
Grade, and control the operation rule of signal by controlled circuit power conversion circuit W1 bridge arm power switch S1, S2, S3, S4 and
The operation logic of output relay group W2 determines.After the hardware configuration of intelligent digital power supply completes, controlled circuit is just
Often it there is certain operation logic when work, how the computer program for no matter how controlling main control chip U1 upgrades optimization, master control
Chip U1, which is exported, to be required to abide by specific operation rule to the control signal of controlled circuit, so that controlled circuit is normally being transported
It works under row logic, and has these specific operation rules with regard to burning in monitoring devices U2.Main control chip U1 and monitoring devices U2
Between there are direct communication link, therefore monitoring devices U2 uses One Time Programmable chip, to avoid in monitoring devices U2
The operation rule of burning is forced to change.
In intelligent digital power supply, the control signal for controlling different controlled circuits has different operation rules, and is controlling
When signal violates operation rule, the processing that monitoring devices U2 is needed to be implemented under the different circuit states of controlled circuit is acted also not
Together.Below with power switch S1, S2, S3, S4 and output relay in intelligent digital power supply in power conversion circuit W1 bridge arm
For group two controlled circuits of W2, processing of the monitoring devices U2 when monitoring that control signal violates default operation rule is acted
It explains.
One, power conversion circuit W1 as shown in Figure 2, power conversion circuit W1 are the lists using unipolarity modulation system
Phase inverter circuit, including connecing two groups of bridge arms between power input positive terminal and power input negative pole end, controlled circuit is
Power switch S1, S2 and power switch S3, S4 on another group of bridge arm, main control chip U1 on one group of bridge arm pass through
Four signal output port PWM 1, PWM 2, PWM 3, PWM 4 export control signal control respectively power switch S1, S2,
S3, S4 ON/OFF.Monitoring devices U2 is logical by receiver port PA2, PA3, PA4, PA5 real-time monitoring main control chip U1
Cross the control signal that signal output port PWM 1, PWM 2, PWM 3, PWM 4 are exported.Main control chip U1 and controlled circuit it
Between be connected with the switching circuit D1 controlled by monitoring devices U2, monitoring devices U2 can block master by disconnecting switching circuit D1
Control chip U1 is exported to the control signal of power switch S1, S2, S3, S4.
Power switch S1, S2 are power frequency wave switching tubes, and rated operation frequency f1 is 50 Hz, and power switch S3, S4 are high frequencies
Wave switching tube, rated operation frequency f2 are 20KHz, and the excessively high conduction loss that can cause power switch of working frequency increases, work
Underfrequency will lead to the saturation of the magnetic element in circuit；In normal operating conditions, upper two power of same group of bridge arm
Switch does not allow to simultaneously turn on, otherwise the bridgc arm short of power conversion circuit W1, will lead to the damage of intelligent digital power supply or draws
Send out safety accident.Therefore, main control chip U1 is exported according to the operation logic of power conversion circuit W1 and gives power conversion circuit W1
Control signal following operation rule is set:
Operation rule 1: the ratio n1 of the actual switch frequency sf1 and rated operation frequency f1 of power switch S1, S2=
Sf1/ f1 meets: 0.5≤n1≤2, i.e. 25Hz≤sf1≤100Hz；
Operation rule 2: the ratio n2 of the actual switch frequency sf2 and rated operation frequency f2 of power switch S3, S4=
Sf2/ f2 meets: 0.5≤n2≤2, i.e. 10KHz≤sf2≤40KHz；
Operation rule 3: when power switch S1 is connected, power switch S2 necessarily is in off-state, and needs to be spaced one
Dead time t；When power switch S2 is opened, power switch S1 necessarily is in off-state, and needs to be spaced one dead zone
Time t；
Operation rule 4: when power switch S3 is connected, power switch S4 necessarily is in off-state, and needs to be spaced one
Dead time t；When power switch S4 is connected, power switch S3 necessarily is in off-state, and needs to be spaced one dead zone
Time t.
When main control chip U1 virus infection make control main control chip U1 output control signal computer program be tampered,
Or when other exceptions occurs in the computer program of intelligent digital power supply, main control chip U1 generates logic error, so that master control
Chip U1, which is exported, violates above-mentioned operation rule 1,2,3 or 4 to the control signal of power conversion circuit W1, causes: power switch S1,
The switching frequency of S2 exceeds the range of 25Hz ~ 100Hz；Or the switching frequency of power switch S3, S4 exceed 10KHz ~ 40KHz
Range；Perhaps power switch S1, S2 simultaneously turn on or power switch S1, S2 conducting time be less than dead time t=
250ns；Perhaps power switch S3, S4 simultaneously turn on or power switch S3, S4 conducting time be less than dead time t=
250ns.At this point, if monitoring devices U2 monitors the behavior of the violation operation rule to will lead to controlled circuit, there are bridgc arm shorts
Danger is just disconnected immediately by signal output port OE control switch circuit D1, is exported to block main control chip U1 to power
The control signal of translation circuit W1, so that four power switch S1, S2, S3, S4 of power conversion circuit W1 are completely in disconnection
State avoids power conversion circuit W1 or other power devices from damaging.After monitoring devices U2 block control signal, the control is recorded
Signal processed violates the number and duration of operation rule.When the behavior of the violation in 1 prespecified minutes is super
When crossing 10 times, monitoring devices U2 restarts letter to the receiver port B1 of main control chip U1 transmitting by signal output port B2
Number, enable the computer program in main control chip U1 restart.If the main control chip U1 of intelligent digital power supply is in operation computer journey
The control signal exported when 1.0 version of sequence is normal, and after being upgraded to 2.0 versions, program is leaky or unstable, causes to lead
It controls chip U1 and generates logic error, export and violate above-mentioned operation rule 1,2,3 or 4 to the control signal of power conversion circuit W1,
Then monitoring devices U2 transmits reset signal to the reseting port RST of main control chip U1 by signal issuing side mouth PA1, enables master control core
The computer program of piece U1 returns to 1.0 versions in the early time.Meanwhile monitoring devices U2 transmits alarm by signal output port A2
Receiver port A1 of the signal to main control chip U1, acceptable external signal an alert, to make intelligent digital power supply report
Fault message reminds the user to have an abnormal conditions, user can the failure in time to intelligent digital power supply handle, keep away
Exempt from the damage of intelligent digital power supply or causes safety accident.
For power switch S1, S2, S3, S4 of power conversion circuit W1, deviate rated operation frequency in its working frequency
It, also can be to the workability of power conversion circuit W1 when the degree that a certain range still deviates also is unlikely to violate operation rule 1,2
It can have an impact, therefore for operation rule 1 and operation rule 2, and have the operation rule of refinement:
Operation rule 1.1: the actual switch frequency sf1 of power switch S1 and S2 meet: 40Hz≤sf1≤60Hz；
Operation rule 2.1: the actual switch frequency sf2 of power switch S3 and S4 meet: 18KHz≤sf2≤
22KHz。
Monitoring devices U2 monitors that main control chip U1 is exported and violates above-mentioned fortune to the control signal of power conversion circuit W1
Line discipline 5 or 6, power conversion circuit W1 can also be worked normally at this time, therefore not need to block control signal immediately.Monitor
Part U2 record the control signal violate operation rule number and duration, when in 1 prespecified minutes should
When the behavior of violation is more than 10 times, monitoring devices U2 transmits alarm signal to the letter of main control chip U1 by signal output port A2
Number receiving port A1, can also external signal an alert, to make intelligent digital power supply report fault message to remind user
There are abnormal conditions.
Two, controlled circuit output relay group W2 as shown in Figure 1, by AND gate circuit D2 extend controlled end, one by
It controls end and receives the control signal from main control chip U1 signal issuing side mouth CON1, another controlled end, which receives, comes from monitoring devices
The control signal of U2 signal issuing side mouth CON2.When the two control signals are all high level, the high electricity of AND gate circuit D2 output
It is flat, to connect output relay group W2；When to have one be low level in the two control signals, AND gate circuit D2 exports low electricity
It is flat, to disconnect output relay group W2.Monitoring devices U2 passes through the port receiver port PA6 real-time monitoring main control chip U1
The control signal exported by the signal issuing side port mouth CON1.
The circuit of the intelligent digital power supply further includes that the voltage sampled to the input voltage of power conversion circuit W1 is adopted
Sample circuit V1, the voltage that the input voltage of output voltage and output relay group W2 to power conversion circuit W1 is sampled are adopted
Sample circuit V2, the voltage sampling circuit V3 that the output voltage of output relay group W2 is sampled.Voltage sampling circuit V1,
V2, V3 can be realized using difference channel or Hall voltage sensor etc..
Voltage sampling circuit V1, V2, V3 receive the signal that the voltage signal sampled is respectively outputted to main control chip U1
Receiver port AD21, AD22, AD23 of port AD11, AD12, AD13 and monitoring devices U2, main control chip U1 and monitor
Part U2 judged according to the sampled voltage of voltage sampling circuit V1, V2, V3 intelligent digital power supply power conversion circuit W1, output after
The operating status of the circuits such as electric appliance group W2.If power conversion circuit W1 normal operation, AND gate circuit D2 should export high level, make
Output relay group W2 is in an ON state；If power conversion circuit W1 exception or intelligent digital power supply are due to other abnormal feelings
Condition is in malfunction as input voltage is low, then AND gate circuit D2 should export low level, and output relay group W2 is made to be in disconnected
Open state.Therefore, main control chip U1 is exported to the control of output relay group W2 according to the operation logic of output relay group W2
Following operation rule is arranged in signal processed:
Operation rule 1: if power conversion circuit W1 works well, signal issuing side mouth CON1 should export high level to
AND gate circuit D2 connects output relay group W2；
Operation rule 2: if power conversion circuit W1 operating is abnormal, signal issuing side mouth CON1 should export low level to
AND gate circuit D2 disconnects output relay group W2；
Operation rule 3: if intelligent digital power supply is in malfunction, signal issuing side mouth CON1 should export low level
AND gate circuit D2 is given, output relay group W2 is disconnected.
When power conversion circuit W1 works well, main control chip U1 should export this high by signal issuing side mouth CON1
Level but without output signal or outputs low level at this time, that is, violates operation rule 1, lead to output relay group W2
It can not work normally, whether monitoring devices U2 just enables the computer program in main control chip U1 restart, then monitor control signal and can
Restore normal, if still can not work normally, transmits alarm signal to main control chip U1 or external signal an alert, from
And make intelligent digital power supply report fault message to remind user there are abnormal conditions.
It is in malfunction when power conversion circuit W1 operates abnormal or intelligent digital power supply, main body circuit occurs different
Often, main control chip U1 should export low level by signal issuing side mouth CON1 to this, at this time but without output signal or defeated
High level is gone out, that is, has violated operation rule 2 or 3, has caused there is external electric energy to carry out instead by output relay group W2
The danger of filling, monitoring devices U2 just replace main control chip U1 to provide low level to AND gate circuit D2, so that AND gate circuit D2 is exported
Low level avoids intelligent digital power supply from damaging or cause safety accident to control output relay group W2 disconnection.
