Detailed Description
The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments, and it is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present invention, based on the embodiments of the present invention.
Referring to fig. 1-5, the present embodiment provides a line fault simulation apparatus, which includes an MCU control module, a power module, at least two disconnection simulation modules, and at least one misconnection simulation module.
The power supply module is used for being connected with an external power supply through the control power supply interface, and is used for supplying power to the MCU control module, each circuit breaking simulation module and each misconnection simulation module.
The MCU control module is used for being connected with external interaction equipment or an upper computer through a communication interface, the communication interface can be a communication bus interface, and the MCU control module is used for carrying out breaking or switching-on setting on the broken circuit simulation module and carrying out line misconnection or normal line connection setting on the misconnection simulation module according to line fault simulation requirements sent by the external interaction equipment or the upper computer.
Each misconnection simulation module is used for simulating misconnection faults of each circuit group in a one-to-one correspondence manner, each circuit breaking simulation module is used for simulating circuit breaking faults of each circuit in a one-to-one correspondence manner, and two circuit breaking simulation modules and one misconnection simulation module are used for jointly completing fault simulation of one circuit group. The two circuit breaking simulation modules used for jointly completing the fault simulation of the same circuit group are a first circuit breaking simulation module and a second circuit breaking simulation module respectively. The first line outlet end of the staggered connection simulation module is connected with the second end of the first line. The wire inlet end of the second circuit breaking simulation module is connected with the first end of the second circuit of the circuit group, the wire outlet end of the second circuit breaking simulation module is connected with the second wire inlet end of the misconnection simulation module, and the second wire outlet end of the misconnection simulation module is connected with the second end of the second circuit.
When the first wire inlet end and the first wire outlet end of the misconnection simulation module are connected and the second wire inlet end and the second wire outlet end of the misconnection simulation module are connected, the misconnection simulation module is normally connected, namely: the circuit group corresponding to the misconnection simulation module is in a normal connection state. When the first wire inlet end and the second wire outlet end of the misconnection simulation module are connected and the second wire inlet end and the first wire outlet end of the misconnection simulation module are connected, the misconnection simulation module is indicated to be misconnected, namely: the circuit group corresponding to the misconnection simulation module is in a misconnection state.
Each open circuit control end of the MCU control module is connected with the instruction end of each open circuit simulation module in a one-to-one correspondence manner, and each misconnection control end of the MCU control module is connected with the instruction end of each misconnection simulation module in a one-to-one correspondence manner.
The process principle of the line fault simulation device for line fault simulation implemented by the embodiment is specifically as follows:
when line breaking fault simulation is carried out, the MCU control module generates a first instruction, the first instruction comprises line information to be broken, the first instruction reaches the broken circuit simulation module through the broken circuit control end and reaches the misconnection simulation module through the misconnection control end, the line to be broken is broken between the line inlet end and the line outlet end of the broken circuit simulation module corresponding to the line to be broken, and at least the misconnection simulation module corresponding to the line to be broken is normally connected. Preferably, all the misconnection simulation modules are connected normally at this time.
When line misconnection fault simulation is carried out, the MCU control module generates a second instruction, the second instruction comprises line group information needing misconnection, the second instruction reaches the circuit breaking simulation module through the circuit breaking control end and reaches the misconnection simulation module through the misconnection control end, so that the misconnection simulation modules corresponding to the line groups needing misconnection are misconnected, and the wire inlet ends and the wire outlet ends of the circuit breaking simulation modules corresponding to the line groups needing misconnection are connected. Preferably, all other misconnection analog modules are connected normally at the same time.
It can be known that the line fault simulation device implemented in this embodiment cannot perform line open fault simulation and line misconnection fault simulation on the same line group at the same time. When the line break fault simulation and the line misconnection fault simulation are simultaneously performed, the line break fault simulation is performed on the first part of the line group, and the line misconnection fault simulation is performed on the second part of the line group. Meanwhile, when the circuit breaking fault simulation is performed on the first part of circuit group, the breaking of the corresponding circuit should not affect the circuit misconnection fault simulation of the second part of circuit group, namely: the conduction between each wire inlet end (first wire inlet end and second wire inlet end) of the misconnection simulation module for carrying out the line misconnection fault simulation and the first end of each wire (first wire and second wire) of the line group corresponding to the misconnection simulation module is not influenced, and the conduction between each wire outlet end (first wire outlet end and second wire outlet end) of the misconnection simulation module for carrying out the line misconnection fault simulation and the second end of each wire (first wire and second wire) of the line group corresponding to the misconnection fault simulation module is not influenced. Correspondingly, when the second part of the line group is subjected to line fault connection fault simulation, the fault connection of the corresponding line does not affect the first part of the line group to perform line open circuit fault simulation, namely: the conduction between the respective outlet terminals of the circuit breaking simulation module performing the circuit breaking fault simulation and the second terminal of the circuit (first circuit or second circuit) to which the circuit breaking simulation module is connected is not affected. Based on the principle, when the circuit breaking fault simulation and the circuit misconnection fault simulation are simultaneously carried out, the MCU control module generates a third instruction, the third instruction comprises circuit information to be broken and circuit group information to be misconnected, and the third instruction reaches the circuit breaking simulation module through the circuit breaking control end and reaches the misconnection simulation module through the misconnection control end, so that the misconnection simulation module corresponding to the circuit group to be misconnected is misconnected, the circuit breaking simulation module corresponding to the circuit to be broken is disconnected, and meanwhile, the misconnection simulation module corresponding to the circuit group corresponding to the circuit breaking simulation module is normally connected.
After the line fault simulation device realized by the embodiment is connected to a line requiring fault simulation, the MCU control module generates a first instruction, a second instruction or a third instruction according to line fault simulation requirements sent by external interaction equipment or an upper computer, after each circuit breaking simulation module receives the first instruction, the corresponding circuit breaking simulation module executes a breaking action, after each circuit breaking simulation module receives the second instruction, the corresponding circuit breaking simulation module is in misconnection, after each circuit breaking simulation module and each misconnection simulation module receive the third instruction, the corresponding circuit breaking simulation module executes the breaking action and the corresponding misconnection simulation module is in misconnection, and finally the required fault simulation is completed.
