Abstract
The utility model relates to the technical field of microcomputer control of export diesel locomotives, and especially relates to a novel microcomputer test bench. The novel microcomputer test bench comprises a microcomputer test platform. The microcomputer test platform is connected with a locomotive microcomputer A and a locomotive microcomputer B. The locomotive microcomputer A and the locomotive microcomputer B are respectively connected with a display screen A and a display screen B. The microcomputer test platform is further connected with a test platform display screen, a CPU and expansion module, an analog quantity voltage source and an analog quantity current source. The utility model is applicable to the locomotives for Argentina; after the locomotives are exported to Argentina, the performance of locomotive microcomputer systems can be detected comprehensively by means of the microcomputer test bench when microcomputer system failures occur, so that the fault points of the locomotive microcomputer systems can be conveniently determined, and more convenient conditions are created for the operation of the locomotives overseas.
Description
Technical field
The utility model relates to the Control Technique of Microcomputer field of exported diesel locomotives, especially a kind of novel computer test bed.
Background technology
Argentina's locomotive is that company's emphasis exports overseas locomotive project, locomotive adopts brand-new microcomputer to control, new locomotive microcomputer system is two micro-architectures and cold standby each other, each system comprises CPU, digital quantity I/O simultaneously, frequency quantity input, analog quantity detection etc., signal comes from all vent external sensors, comprises voltage, electric current, locomotive speed, every motor speed, oil temperature, oil pressure etc., signal is various, and the locomotive microcomputer display screen is Spanish/Chinese display.In company, existing computer test bed can not be detected the microsystem of Argentinian locomotive, therefore redesign, develop a set of testing table that can detect Argentinian locomotive microcomputer system.
The utility model content
In order to overcome the deficiency of existing technology, the utility model provides a kind of novel computer test bed.
The utility model solves the technical scheme that its technical matters adopts: a kind of novel computer test bed, comprise computer test bed, it is characterized in that, described computer test bed is connected with locomotive microcomputer A and locomotive microcomputer B, described locomotive microcomputer A is connected respectively display screen A and display screen B with locomotive microcomputer B, and described computer test bed is also distinguished joint test platform display screen, CPU and expansion module, analog quantity voltage source and analog quantity current source.
The beneficial effects of the utility model are, the utility model is applicable to Argentinian car, after locomotive exports to Argentina, during computer system failure, by this computer test bed, can comprehensively detect the performance of locomotive microcomputer system, judge easily the trouble spot of locomotive microcomputer system, for locomotive moves in overseas, create convenience preferably.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Embodiment
As Fig. 1 is structural representation of the present utility model, a kind of novel computer test bed, comprise computer test bed, described computer test bed is connected with locomotive microcomputer A and locomotive microcomputer B, described locomotive microcomputer A is connected respectively display screen A and display screen B with locomotive microcomputer B, and described computer test bed is also distinguished joint test platform display screen, CPU and expansion module, analog quantity voltage source and analog quantity current source.The preferred S7-200 CPU of CPU.Computer test bed and S7-200 CPU and expansion module carry out the Point-to-Point Data exchange by the PPI communications protocol.Computer test bed and analog quantity current source carry out exchanges data by the MODBUS-RTU communications protocol.
For the two micro-architectures of Argentinian locomotive, this novel computer test bed can carry out the test of A machine or the test of B machine in the inner selection of testing table, has solved the difficult problem of two microcomputer testings.And the configuration software inner language arranges and interface editing, is provided with the selection of the test interface of Chinese, Spanish, in convenience, square staff and Argentinian side staff participate in microcomputer testing.
The utility model preferably adopts S7-200 CPU, by the configuration to S7-200 PLC, can simulate switching value signals all on locomotive in testing software, the output of testing table is as the input of microsystem, the output of microsystem turns back to again testing table, the closed loop of stroke detection.
The utility model is controlled controllable electric power by the MODBUS-RTU agreement, simulates all analog signalses of locomotive, checks that the locomotive microcomputer system display judges that whether the board of locomotive microcomputer system is normal.In addition, be provided with special digital adjustable position device, by PLC, it carried out to gear control, can realize the simulation of various temperature signals on locomotive.
The utility model is applicable to Argentinian car, after locomotive exports to Argentina, during computer system failure, by this computer test bed, can comprehensively detect the performance of locomotive microcomputer system, judge easily the trouble spot of locomotive microcomputer system, for locomotive moves in overseas, created convenience preferably.
