Abstract
The utility model discloses an electronic circuit fault setting device, and relates to a circuit fault setting teaching instrument. The device comprises a microprocessor, a keyboard input unit and driving circuit, a liquid crystal display screen and driving circuit, a communication interface and circuit, a memory, a fault point selection circuit and a fault box. The fault point selection circuit comprises at least one fault point driving circuit capable of setting connection and disconnection and a group of normally closed fault point relays driven by the fault point driving circuit correspondingly. Through a host machine, the microprocessor can be operated to drive the corresponding relay coil to be energized or deenergized, and the purposes of connecting and disconnecting the circuit is achieved. The whole circuit is placed in the fault box to only expose a wiring terminal, thus a student can not see the connection and disconnection states of the circuit in fault elimination and should test the circuit according to a fault phenomenon and find a fault after analysis, and the teaching effect and efficiency are raised. The electronic circuit fault setting device has the advantages of simple structure, low cost, convenient setting operation of the fault, and the elimination of hidden trouble.
Description
Technical field
The utility model relates to a kind of fault instruments used for education is set, and specifically is a kind of electronic circuit fault setting device, is particularly useful for universities and secondary specialized schools and training organization's fault eliminating teaching and training.
Background technology
In the teaching of big, special secondary school and some professional training mechanisms, often need the teacher that the circuit of instruments used for education is arranged fault, by the student fault is analyzed, tests, got rid of then, with the professional skill of this training of students.Present way generally all is to adopt the terminal screw on the connecting terminal block to be unclamped, to fill in spaghetti or with ways such as lead fracture, artificially lead to be disconnected.Though also can play the training effect, but because this method can not need to carry out the circuit test analysis according to phenomenon of the failure sometimes, as long as adopt simple approach such as checking the connection terminal screw can find weak point, fall flat, even had a strong impact on the effect of training.That failed operation is set is loaded down with trivial details, time-consuming for this method in addition, easily produces potential safety hazard, and operation can reduce the life-span of device greatly and increase the use amount of consumptive material frequently simultaneously.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the utility model provides a kind of electronic circuit fault that dress is set
Put, simple in structure, safe and reliable, detect effective.
The utility model is realized with the following technical scheme of saying: a kind of electronic circuit fault setting device, circuit and communication interface and circuit thereof are selected in the keyboard input block that comprise microprocessor, is connected respectively with microprocessor and driving circuit, LCDs and driving circuit thereof, storer, trouble spot, and communication interface and circuit thereof realize that by the network switch and host computer communication is connected; Select circuit to be installed in the fault box trouble spot.
Described trouble spot selects circuit to comprise trouble spot driving circuit 8 and the normally closed trouble spot relay group that at least one can establish break-make; The normally closed contact of normally closed trouble spot relay group is connected with the outlet connection terminal with corresponding trouble spot lambda line connection terminal respectively
What described communication interface and circuit thereof adopted is that the MODBUS agreement is connected with host computer.
Described fault box is made with iron sheet or opaque plastic.
The beneficial effects of the utility model are: by host computer fault is set, because entire circuit places in the fault box, only reserve connection terminal, make the student when fault is got rid of, can't see the on off operating mode of circuit, find out fault after must testing, analyze circuit according to phenomenon of the failure.Teaching efficiency and efficient have been improved.It is simple in structure, and is with low cost, and the setting operation of fault is easy, has also eliminated potential safety hazard simultaneously.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific implementation method.
Fig. 1 is the utility model control principle block diagram;
Fig. 2 is the circuit diagram of a kind of embodiment of fault point selection circuit;
Fig. 3 is that the fault point relay arranges circuit diagram;
Fig. 4 adopts instrument automation experimental teaching fault of the present utility model that system diagram is set.
Embodiment
As Figure 1-3, a kind of electronic circuit fault setting device has a microprocessor 1, the keyboard input block that is connected with microprocessor 1 respectively and driving circuit 2, LCDs and driving circuit 3 thereof, storer 5, trouble spot to select circuit 6 and communication interface and circuit 4 thereof, and communication interface and circuit 4 thereof realize that with host computer 10 communication is connected by the network switch; The trouble spot selects circuit 6 to be installed in the fault box 7.
As shown in Figure 2, the trouble spot driving circuit 8 that the trouble spot is selected circuit 6 to comprise can to establish break-make and with trouble spot normally closed trouble spot relay group 9(K1, K2, K3 one to one ...), but the fault set-point number of break-make is decided according to the actual requirements, and is example with 8 here.
As shown in Figure 3, the normally closed contact of normally closed trouble spot relay group 9 is connected with outlet connection terminal 12 with corresponding trouble spot lambda line connection terminal 11 respectively.Entire circuit places in the fault box, only reserves connection terminal outside.But drive the charged or outage of corresponding relay coil by the host computer operating microprocessor, reaching this circuit is the purpose that disconnects or connect.
As shown in Figure 4, at the instrument automation experimental teaching fault that adopts electronic circuit fault setting device of the present utility model management system is set, 13 is LCD display among the figure, 14 is button, and 15 is wire harness, and 16 is aviation plug, 17 is the netting twine interface socket, 18 is electronic circuit fault setting device, and 19 is the network switch, and 20 is the instrument automation experimental teaching equipment.Electronic circuit fault setting device 18 adopts wire harness 15 to be connected with instrument automation experimental teaching equipment 20, and the communication interface of electronic circuit fault setting device and circuit 4 thereof are connected with host computer 10 by the network switch 19.
When needs arrange fault, fault in host computer 10 as shown in Figure 4 arranges corresponding trouble spot switch is set in the management system is the state that disconnects or connect, this information is based on the MODBUS agreement, be transferred to microprocessor 1 in the electronic circuit fault setting device by netting twine, microprocessor 1 selects the coil of some relay in the corresponding trouble spot relay group 9 of circuit 6 drivings whether charged by the trouble spot then, reach the purpose that the Long-distance Control relay contact disconnects or connects, when the fault setting was finished, the setting of demonstration fault was finished in LCD display 13.Fault is got rid of personnel can't be by simple observation, unclamp way such as terminal finds fault, and must carry out test analysis according to phenomenon of the failure.If fault eliminating personnel think that certain bar circuit has open circuit fault or short trouble, can between top connection terminal and bottom connection terminal, connect a lead in addition with the open circuit fault reparation, or directly disconnect the top connection terminal with the short trouble reparation, when the fault eliminating is finished, by the relevant information of button 14 input faults eliminating, and confirm to finish, pass information back host computer 10 by network, thereby improved the authenticity of simulated training, the simultaneous faults setting operation is more convenient, safety also.
