Overall design block diagram of the present utility model is as Fig. 1; the overall circuit of YAG laser bonding entity power supply is as Fig. 2; in figure, 4 is the input of 220V electric main; through D1; D2 and C1; the bus DC voltage Vbus produced after C2 voltage multiplying rectifier is approximately 620V; L1 is the big current hollow power inductor of 180uH; LP1 is xenon lamp; Q1 is the IGBT module of 400A/1200V, and D3 is loop fly-wheel diode, and 1 is IGBT Drive Protecting Circuit; 2 is main control module, 3 for rated current be the Hall current mutual inductor module of 400A.Circuit working control principle is: set given reference current, measures main circuit current feed back to primary controller by Hall current mutual inductor, and master controller, by PWM control IGBT, makes the current stabilization flowing through xenon lamp in loop in the reference current of setting.
Because YAG laser bonding entity power bus voltage Vbus reaches 620V, main circuit current is maximum reaches 400A, so large electric current and voltage is not suitable for being applied to teaching experiment, so add one in this solution to be enclosed within low-voltage small area analysis experimental circuit under safe voltage, its circuit theory is identical with the circuit theory of entity power supply, and simulated experiment circuit module and entity power circuit block are undertaken communicating by CAN and realize operating control synchronization; Simultaneously in order to can online automatic detection student build the electronic circuit of connection, the two ends of each connecting line are respectively connected in series a controllable switch in circuit, this controllable switch can use but be not limited to MOSFET, relay etc., this solution employs a two contact relay, relay contact is respectively connected on the two ends of connecting line, just other connecting line in this connecting line and circuit can be kept apart when detecting connecting line like this, this connecting line of measurement that just can be independent whether exact connect ion.For student carry out starting experimental implementation circuit as shown in Figure 3; in figure, 5 is 9V AC power; the bus DC voltage Vbus that it produces after voltage multiplying rectifier is approximately 25V; L2 is the small area analysis power inductance of 180uH; the great power LED of LP2 is a rated current to be 1A forward voltage drop be 6V is used for replacing xenon lamp; Q2 is the miniwatt IGBT of 10A/600V; D4 is loop fly-wheel diode; 6 for rated current be the Hall current mutual inductor of 1A; 7 is IGBT Drive Protecting Circuit; 8 is experimental circuit main control module, and S is relay normally closed interlock.Its job control principle is identical with the control principle of entity power supply.In order to allow experimental simulation circuit and entity power circuit synchronous operation work, student is felt, and control simulation circuit is just as controlled entity power supply, by CAN experimental simulation circuit linked together with entity power circuit and communicate, parameter on operation setting entity power supply, master controller on entity power supply will be sent to same parameter the master controller of experimental simulation circuit by CAN communication, each action that operation performs entity power supply can notify experimental simulation circuit by CAN, so just reaches general synchronization.
In order to can the electronic connecting line road of on-line real-time measuremen experimental simulation circuit, also need to increase testing circuit, as shown in Figure 4, intersection point between connecting line and connecting line is called end points, line socket on experiment porch is connected with end points, in experimental circuit, each end points has several connecting lines to be attached thereto, and this end points is just provided with several terminals of connecting wire socket, or have more at most a terminals of connecting wire socket (as terminal block over the ground, have more one as other detection terminal), detecting each connecting line is detect unit with end points, each end points has 17 such testing circuits, in figure, S is relay normally closed interlock, 10, 11 is experiment porch end points line socket, 12, 13 for needing correct connecting line, in 23 9 are detect voltage by the outlet line of experimental simulation circuit master control module controls, magnitude of voltage is 5V, in another end points 21 of line 14 is detect level signal by the output enable of experimental simulation circuit master control module controls, U1 is a comparer, Vref is comparator reference voltage--2.5V, 15 is comparator output signal.Connecting line Cleaning Principle for convenience of description, agree as follows term: 1. at inspection end points: whether detecting this end points has the end points of connecting line for examine end points with other end points, such as, be about in Fig. 4 detecting end points 10 with other end points (as end points 11,, 19,22) whether have connecting line to connect, then end points 10 be inspection end points.2. scan end points: whether non-other end points at inspection end points of Scanning Detction has connecting line to be connected to be called scanning end points with examining end points.3. end-point detection voltage signal: experimental simulation circuit master control module controls outputs to the voltage of in inspection end points 23 9, when end-point detection voltage signal is 5V effectively, invalid during 0V; Any time has and only has an end-point detection voltage signal effective, or void in whole.4. end points scan enable signals: experimental simulation circuit master control module controls output enable signal detects level signal to 14 in scanning end points 21, whether allow to detect this scanning end points has connecting line to be connected with examining end points, being that enable signal is effective when level signal is high level, is that enable signal is invalid during low level; Any time has and only has a connecting line sense enable signal effective, or void in whole; During Scanning Detction scanning end points, 9 end-point detection voltages in inspection end points 23 are remained valid.Any time same end points end-point detection voltage and end points scan enable signals can not simultaneously effectively.
Connection detection circuit principle of work is as follows: after student connects the circuit that will test, press start button by circuit working, after main control module detects enabling signal, now main control module does not also allow experimental circuit work, it first outputs signal and allows all actuating of relay, all normally closed contacts are disconnected, then end-point detection one by one, such as, in Fig. 4, between end points 10 and end points 11,12 lines are exact connect ion, the connection status of present detection end points 10, now end points 10 is at inspection end points, master controller exit point detectable voltage signals is effectively on end points 10, exit point scan enable signals is effectively on end points 11 simultaneously, if 12 have correct connecting line, now because 14 is high level, PNP triode Q3E-C pole is communicated with, such end-point detection voltage signal 9 is through D5, R1 (=1K), connecting line 12, R2 (=1K), PNP triode Q3, R3 (=100K), (R4=30K, R5=30K, R6=10K) ground is finally connected to, the voltage produced 16 like this will higher than reference voltage Vref, comparer U1 exports 15 will export a high level, if 12 do not have connecting line to connect, the output of 15 is exactly low level.So when main control module exit point detectable voltage signals to 9 effectively, end points scan enable signals to 14 effectively after, detect that high level then 12 just has correct connecting line to connect, if just do not have connecting line to connect for low level 15.The enable signal of experimental simulation main circuit controller output end spot scan afterwards successively Scanning Detction other remain the end points that do not detect, if 15 have high level output in 17 of other end points, this end points has connecting line to be connected with this examine end points, if be low level, does not connect.
Fig. 5, Fig. 6, Fig. 7 are the schematic diagram of electronic circuit incorrect link.
If just as student experimenting application, then experimental simulation circuit just can complete the simulation of various line fault, because each connecting line in circuit has a relay to be connected with it, these relays can control separately again.But when carrying out level examination, if the circuit that student connects is incorrect, then circuit was with regard to cisco unity malfunction, so circuit just can not simulated failure allow student carry out the exercise question examination of malfunction elimination.In order to address this problem, this complete equipment turn increases circuit kit and experimental simulation circuit is the same, be referred to as fault simulation circuit, the end points that the end points of each connecting line in fault simulation circuit is corresponding with experimental simulation circuit is connected, and such fault simulation circuit just looks like that the shadow of experimental simulation circuit is the same.Under normal circumstances, all relay contacts in fault simulation circuit disconnect, and fault simulation circuit is not worked, and would not have influence on the operation of experimental simulation circuit like this, and only when malfunction elimination exercise question is taken an examination, it just participates in work.When fault simulation circuit working, all relays of experimental simulation circuit all disconnect, and make experimental simulation circuit not affect the normal operation of fault simulation circuit.In fault simulation circuit there is fault with regard to simulating the circuit be associated in certain relay break contact of master control module controls, when student have found the tram of trouble spot, just illustrates that it correctly can eliminate fault.
