Abstract
T-shaped with H type monitoring record plug-in detection apparatus in the locomotive that the utility model provides, it comprise respectively with T-shaped monitoring record plug-in unit or the locomotive CPU that is connected with H type monitoring record plug-in unit, locomotive CPU comprises three I/O interfaces, two I/O interfaces are connected in series a resistance respectively wherein, the other end of two resistance is connected with another one I/O interface together.The utility model by be connected to H type monitoring record plate and T-shaped monitoring record plate CPU I/O interface on the energising of resistance time corresponding situation judgement, easily can judge the type of the monitoring record plate of current replacing fast.
Description
Technical field
The utility model relates to locomotive monitor field, particularly relates in a kind of locomotive T-shaped with H type monitoring record plug-in detection apparatus.
Background technology
H type monitoring record plug-in unit is mainly in order to solve the problem and the Novel monitoring record plug-in unit researched and developed that stop production for the storage chip storing LKJ vehicle-mounted control program and LKJ vehicle-mounted basic data in LKJ2000 type train operation monitoring device (hereinafter referred to as LKJ).T-shaped monitoring record plug-in unit is mainly using the problem that transponder upgrades LKJ basic data and the plug-in unit researched and developed to solve.In actual use, need to change H type plug-in unit or T plug-in unit according to use, therefore need to judge which model the plug-in unit of current use is.
Utility model content
The technical problems to be solved in the utility model is to provide T-shaped with H type monitoring record plug-in detection apparatus in a kind of locomotive, cannot judge which kind of problem current plug-in unit belong to what solve that prior art exists.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: T-shaped with H type monitoring record plug-in detection apparatus in locomotive, it comprise respectively with T-shaped monitoring record plug-in unit or the locomotive CPU that is connected with H type monitoring record plug-in unit, locomotive CPU comprises three I/O interfaces, two I/O interfaces are connected in series a resistance respectively wherein, the other end of two resistance is connected with another one I/O interface together.
Described locomotive CPU refers to the CPU of LKJ equipment, and T-shaped monitoring record plug-in unit and H type monitoring record plug-in unit are all plugged on LKJ equipment.
The output circuit of locomotive CPU tri-I/O interfaces is all serially connected with LED indicating circuit.
The beneficial effects of the utility model: by be connected to H type monitoring record plate and T-shaped monitoring record plate CPU I/O interface on the energising of resistance time corresponding situation judgement, easily can judge the type of the monitoring record plate of current replacing fast.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the T-shaped monitoring record plate of the utility model.
Fig. 2 is plug-in detection apparatus figure in embodiment of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
T-shaped with H type monitoring record plug-in detection apparatus in the locomotive that the utility model provides, it selects three I/O interfaces of the CPU of T-shaped monitoring record plug-in unit and H type monitoring record plug-in unit respectively, two I/O interfaces connect a resistance respectively wherein, the other end of two resistance is connected with another one I/O interface together.Locomotive CPU refers to the CPU of LKJ equipment, and T-shaped and H type monitoring record plug-in unit is plugged on LKJ equipment.
Be illustrated in figure 2 the resistance connected mode on T-shaped monitoring record plate and H type monitoring record plate, wherein TP11, TP12, TP13 are I/O interface, first resistance R1 one end is connected on TP11 interface, the second resistance R2 other end is connected on TP13 interface, and the first resistance R1 is connected TP12 interface after being connected with the other end of the second resistance R2 jointly.In the present embodiment, we set when the first resistance R1 is all connected CPU with the second resistance R2, the plate connected is T-shaped monitoring record plate, when having any one not to be connected with CPU in the first resistance R1 with the second resistance R2, is then judged to be H type monitoring record plate.When after replacing monitoring record plate, in deterministic process, electric signal is launched to the first resistance R1 be connected and the second resistance R2 from the TP12 interface of CPU, then CPU receives answer signal, if complete response between CPU and two resistance, then can judge that this plate is T-shaped monitoring record plate, if only and between a resistance have response, then be judged as H type monitoring record plate.
