Embodiment
The utility model will be further described by reference to the accompanying drawings for embodiment below.
As shown in Figure 1, the online early warning device of syntonic type electric locomotive main transformer high temperature, comprise single-chip microcomputer 1, display screen 2, clock 3, register 4, A/D module 5 and warning circuit 6, display screen 2, clock 3, register 4, A/D module 5 are connected with single-chip microcomputer 1 respectively with warning circuit 6, also comprise temperature sensor 7 and atmosphere temperature transducer 8, temperature sensor 7 is connected with A/D module 5 respectively with atmosphere temperature transducer 8.
Described temperature sensor 7 adopts the SMD temperature sensor of DLS.
Described temperature sensor 7 has one at least.
Described temperature sensor 7 is connected with cooling unit.
Described temperature sensor 7 is connected with main transformer radiator and/or composite cooler.
Determine sampled point
In locomotive cooling system, diesel locomotive is mainly diesel coolant cycle cooling system, and electric locomotive is mainly transformer oil and main convertor cooling water circulation cooling system; Diesel locomotive cooling system work efficiency quality finally show cooling unit outlet coolant temperature on, electric locomotive cooling system work efficiency quality finally show on the outlet coolant temperature of main-transformer or composite cooler; When equal thermal value, outlet coolant temperature is lower, cooling system work efficiency is better, but, the size of diesel engine of locomotive, main-transformer, main convertor thermal value determines according to locomotive output power, therefore, is not constant, all by monitoring heat sink inlet temperature, convert as thermal value.The heat interchange of locomotive cooling system is carried out between heat eliminating medium and air, and under different atmospheric temperature, atmospheric density is different, and the heat that the air of same volume carries away is also different, so need too to monitor to atmospheric temperature, converts as atmospheric density.
Therefore, choose the cooling unit in locomotive cooling system, main transformer radiator, composite cooler out temperature and atmospheric temperature and carry out temperature sampling as sampled point.
Technical essential
1, the key technical indexes of reflection locomotive cooling system work efficiency is coolant temperature situation of change, but coolant temperature is not constant, along with the change of locomotive output power, the temperature of heat eliminating medium is also in continuous change, therefore, simple orientates the absolute temperature of heat eliminating medium as alarming threshold value, can not accurately reflect the work efficiency of cooling system.
In order to react locomotive radiating efficiency accurately, the programmed algorithm special to the vehicle-mounted choice of software of locomotive cooling system monitoring device, the technical indicator situation of change of the highest absolute temperature of comprehensive heat eliminating medium, the highest relative temperature, temperature duration, atmospheric temperature, alarming threshold value is set, with 60 seconds for sense cycle carries out computing, by the warning of warning order, the early warning of warning, secondary early warning, one-level early warning, accurately to reflect locomotive cooling system work efficiency.
2, supporting PC software carries out trend analysis
While carrying out real time on-line monitoring to locomotive cooling system heat eliminating medium, to the statistical study of cooling system coolant temperature variation tendency, locomotive cooling system work efficiency also can be reflected.Therefore, can synchronously use PC software, carry out statistical study to the variation tendency of each sense channel data, the overall trend of reflection locomotive cooling system work efficiency, as the supplement Analysis of car-mounted device alarming result.
3, the type selecting of temperature sensor and installation
Locomotive cooling system efficiency on-Line Monitor Device, main detection coolant temperature situation of change, but heat eliminating medium is at pipeline Inner eycle, select plug in sensor, need emptying heat eliminating medium during installation, carry out perforate to cooling system pipeline, mounting process is complicated.Select the SMD temperature sensor of DLS, supporting special erecting frame and heat-insulation layer in this design, install at pipeline outer wall, mounting process is simple.
4, Single-chip Controlling is adopted to report to the police.
Adopt Single-chip Controlling, logical operation is carried out to sampled signal, control LCD screen chinese disply and audio alert, have good man-machine interface.
Result of performance test and real train test show, this unit state is good, dependable performance, steady quality; By the application of the technological means such as the logical operation to sampled signal, Single-chip Controlling, increase warning accuracy rate, there is good man-machine interface; Achieving online evaluation and the early warning of locomotive cooling system radiating efficiency, is the important technical that locomotive cooling system detects in prevention.
