Embodiment
Below in conjunction with the accompanying drawings and embodiment the present invention is further illustrated.
Bus temperature rise online monitoring system of the present invention, including thermistor R5 epoxy resin is filling is fixed on cylinder copper shell
The inside of body 3 composition temperature probe, temperature probe upper end are arranged in temperature measurement module 2, and temperature probe lower end is exposed in temperature measurement module 2
Outside, cylinder copper shell 3 encapsulates thermistor R5 one end and is located at outside temperature measurement module 2, and the other end of cylinder copper shell 3 is located at thermometric
In module 2, temperature measurement module 2 and thermistor R5 are electrically connected, and temperature measurement module 2 is arranged on bus metal shell 4 by support 1
Side, make temperature probe tightly be fitted in the surface of bus metal shell 4, realize the measurement to shell surface temperature, temperature probe
The temperature of bus metal shell 4 is detected, temperature measurement module 2 is arranged on support 1, and support 1 is arranged on bus metal shell 4.
Also comprising series resistance R in temperature conditioning unit, relay K and module, temperature conditioning unit and heat inside the temperature measurement module 2
Quick resistance R5 is electrically connected, and thermistor R5 monitors overtemperature, then relay K node closes, and includes electricity inside collection display device
Source module, MCU controllers, relay J, optocoupler, sampling resistor R1, current-limiting resistance R2 and optocoupler pull-up resistor R3, power supply mould
Block provides required power supply for collection display device and temperature measurement module 2, and when optocoupler is from by the end of conducting, MCU can trigger interruption
Event, collection display device are provided with remote communication interface.
After the system is powered, gathers the J1 relay nodes inside display device and be located at B points, the optocoupler for connecting bottom returns
Road.When temperature conditioning unit inside temperature measurement module 23 does not monitor that temperature exceedes thermistor R5 predetermined temperatures, module
Internal relay K is off, and whole optocoupler loop is off, and optocoupler is sent without interrupt signal；If system
In any one temperature measurement module 23 when monitoring that temperature exceedes thermistor R5 predetermined temperatures, the relay of the inside modules
Device K is closed, and now optocoupler loop turns on, and MCU interrupt logic is triggered, now MCU control relays J1, relay J1 nodes
A points are switched to, voltage sample loop is switched on.
Each thermistor is by corresponding resistance temperature table, the resistance of thermistor when can obtain 60 DEG C by tabling look-up
It is worth, the resistor network and high-accuracy voltage comparator inside resistance cooperation temperature conditioning unit can produce relay K action signal,
So that relay node closure or disconnection.
The multiple temperature measurement modules 23 of the system are sequentially connected in series using plain conductor, and the R in Figure of description 2 represents thermistor
R5, R1 represent sampling resistor R1, and R2 represents current-limiting resistance R2, R3 and represents optocoupler pull-up resistor R3, and plain conductor is in each section of line
Resistance in road is RL, due to of length no more than 10 meters of every section lead, so resistance value is very small, in general less than 1 Europe
Nurse is approximately 0 ohm, and the thermistor R5 in each temperature measurement module 23 is at least 100 ohm, so both are not in a number
In magnitude, this monitoring system is exactly based on the ratio great disparity relation between R and RL, to position the module position that overtemperature occurs, together
When device in J2 relay nodes closure, output alarm signal outward.
Assuming that overtemperature occurs for x-th of temperature measurement module 23 in system, then R1, x RL and x R series connection in voltage sample loop,
And RL is approximately 0 ohm, it is possible to regard R1 and x R series connection as, after MCU voltage samples, relay J1 sections can be obtained
Voltage Ua at point A, according to following calculation formula：
(Vcc-Ua)/R1=Ua/ (x*R),
Vcc is the voltage for accessing circuit, and Vcc, R1, R and Ua are known, it is possible to calculates x=(R1*Ua)/R* (Vcc-
), Ua so that the position of the temperature measurement module 23 of overtemperature occur after judging.
