The invention provides an LKJ equipment detection device. The LKJ equipment detection device comprises an industrial personal computer, a programmable power supply, a main control cabinet and an adapter cabinet, wherein the industrial personal computer is a man-machine interface and is used for setting a testing function and displaying and storing a detection result; the programmable power supply is used for providing a DC (Direct Current) 110V programmable adjustable power supply for LKJ complete machine and single board testing; the main control cabinet is used for receiving an operation instruction coming from the industrial personal computer through an RS485 bus; according to a selected testing project, controlling to output a related testing signal; when the adapter cabinet is used for carrying out the single board testing, an inserting position is provided for each single board to be tested and is used for testing; and an electronic load is provided in a process of testing a power supply board and speed and pulse signals are provided in a process of monitoring and recording board testing. When the LKJ equipment detection device is used, various locomotive condition signals can be relatively accurately simulated; meanwhile, a closed loop testing method is adopted and various types of signals, which are received by an LKJ2000 monitoring device and are generated by the LKJ equipment detection device, are acquired; and a processing condition of various types of the signals of the LKJ2000 monitoring device are monitored, and automatic testing and fault diagnosis functions of the LKJ2000 monitoring device are realized.
Description
technical field [0001] The invention relates to the technical control field of railway signals, in particular to a detection device for LKJ equipment. Background technique [0002] The LKJ train operation monitoring system is an important equipment to ensure the safety of train operation, and its repair and maintenance are crucial. The LKJ equipment detection device is a supporting test and diagnosis equipment for the LKJ2000 monitoring device. At present, the LKJ equipment detection device has the following deficiencies: [0003] (1) Automated testing cannot be performed; [0004] (2) The LKJ host and plug-in cannot be tested at the same time. Contents of the invention [0005] In order to solve the above problems, the present invention provides a LKJ equipment testing device, which can automatically test the LKJ2000 monitoring device and the single board, and can test the LKJ host and the single board at the same time. [0006] The purpose of the present invention is...
