Detailed description of the invention
The utility model is described in more detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of SCM Based Locomotive axle temperature displaying alarm of this utility model, information gathering fills
Put, be arranged on locomotive for gathering locomotive upper bearing (metal) temperature initial data；Single-chip microcomputer 1, is connected with information collecting device, uses
In receiving and processing the bearing temperature initial data from information collecting device, and export control signal；Thermal infrared imager 7, if
It is placed on locomotive the infrared image in order to gather at locomotive upper bearing (metal) and is sent to single-chip microcomputer 1；Data display alarm device, is arranged
Be connected with single-chip microcomputer 1 in driver's cabin, for receive from single-chip microcomputer 1 control signal and show bearing temperature parameter and
Infrared image, and when temperature parameter exceedes normal temperature alarm.
Information collecting device includes temperature sensor 6, temperature sensor 6 through multi-channel electronic switch 4 and cable interface 3 with
Single-chip microcomputer 1 is connected, and electrical switch 4 is controlled by Digiplex 5.In the present embodiment, typically there are eight wheels because of locomotive,
So arranging eight temperature sensors 6.DS18B20 is selected in temperature sensor 6, has ground terminal, digital signal output end and electricity
Source input, DS18B20 supply voltage is 3.0 to 5.5 volts, and temperature-measuring range is-55 to 125 Celsius temperatures, supports multiple spot networking
Function, multiple DS18B20 can be connected in parallel on unified bus, it is achieved multi-point temperature measurement.DS18B20 sensor a integrated digital temperature
Degree sensor, it is possible to directly read dut temperature, can in 93.75 ms and 750 ms, temperature value be converted into respectively 9 and
The digital quantity of 12, thus system structure is simpler, reliability is higher to use DS18B20 to make, the power consumption of chip is very simultaneously
Little, typically need not separately power up.The digital signal of temperature sensor 6 output, directly can be connected with single-chip processor i/o, make connection non-
Often convenient, be digital signal due to transmit on monobus, this makes, and the anti-interference of system is good, reliability is high, transmission away from
Away from from.
In the present embodiment, single-chip microcomputer uses the MCS-51 repeatable erasable AT89C55WD double mcu of series to control.Monolithic
Machine completes the selection of cable interface and controls, and according to the digital quantity of DS18B20 sensor input, shows each axle according to program command
Temperature parameter, in normal temperature range, display green, exceedes normal temperature and then shows redness.Use AT89C55WD double mcu work
Make mode, primarily to solve the required pin problem that controls, raising data-handling capacity and speed.
Data display alarm device 2 includes temperature display charactron and LED bi-colour light, temperature display numeral method axle
Temperature, LED bi-colour light display state, in normal temperature range, display green, exceedes and shows red alarm normal range.In this enforcement
In example, display includes two pieces of CH452 chips, and CH452 connects as shown in Figure 2, the display of charactron temperature and the state of LED
Display independently of one another, therefore uses the mode that two panels CH452 is in parallel with single-chip microcomputer.A piece of can be with 8 common cathode numbers of dynamic driving
Pipe, after same section pin (section A～section G and the arithmetic point) parallel connection of all charactrons by concatenation current-limiting resistance R1(or
R12) section connecting CH452 drives pin SEG0～SEG7, and the negative electrode of each charactron is respectively by DIG0～the DIG7 pin of CH452
It is driven.Concatenation current-limiting resistance the biggest then section of resistance drive electric current the least, the display brightness of charactron is the lowest, R1(or
R12) resistance, should the bigger resistance of prioritizing selection in the case of other condition is identical typically between 100 Ω to 1K Ω
To reduce the power consumption of CH452 chip itself；Another chip block is used for realizing the driving of LED bi-colour light.
In the present embodiment, single-chip microcomputer 1 connects has data storage cell, temperature parameter to store data storage cell to be easy to
Maintenance conditions in the future.
Above this utility model is described in detail, but this utility model is not limited to the above embodiments.All bases
The equivalence that spirit of the present utility model is made changes or modifies, and all should contain in protection domain of the present utility model.
