Fig. 2 is the structural representation of another embodiment of the monitoring device of train bearing temperature of the present utility model.
Embodiment
Be specifically described below in conjunction with the embodiment and the system architecture of Figure of description utility model.
As shown in Figure 1, the monitoring device of train bearing temperature comprises Acquisition Processor 10 and LonWorks line of electric force network interface card 20, wherein:
Acquisition Processor 10 is used to receive the temperature data of bearing in the single-row compartment that first kind digital temperature sensor transmits and the ambient temperature data that the second type digital temperature sensor transmits, temperature data and ambient temperature data according to described bearing are carried out the temperature over-range diagnosis, send bearing overtemperature alarm signal when being diagnosed as the bearing overtemperature;
LonWorks line of electric force network interface card 20 is used for bearing temperature data and/or bearing overtemperature alarm signal from Acquisition Processor 10 are mail to LonWorks line of electric force train communication network, and from bearing temperature data and/or the bearing overtemperature alarm signal of LonWorks line of electric force train communication network reception from other compartments.
In the utility model, Acquisition Processor 10 can adopt two kinds of overtemperature diagnostic methods:
A kind of is absolute temperature rise method, whether promptly judges bearing temperature greater than T (T is the value that definitely transfinites), and the bearing temperature that collects when digital temperature sensor then is diagnosed as the bearing overtemperature during greater than T;
Another kind is relative temperature rise method, promptly judges bearing temperature whether greater than C+ Δ t (C is an ambient temperature, and Δ t is a unique value between 41 ℃-49 ℃ of user's appointment), if when being diagnosed as greater than C+ Δ t, then is diagnosed as the bearing overtemperature.
As a kind of embodiment of the present utility model, as shown in Figure 2, the monitoring device of train bearing temperature can be to comprise: Acquisition Processor 10, LonWorks line of electric force network interface card 20, compartment display 30, digital filter processor 40, first kind digital temperature sensor 52 and the second type digital temperature sensor 54.
In this embodiment, 8 first kind digital temperature sensors 52 are installed on respectively by 8 bearings in described single-row compartment, and per 1 first kind digital temperature sensor is gathered the temperature data of 1 bearing.The second type digital temperature sensor is used to gather the ambient temperature data.
Then, the first kind digital temperature sensor and the second type digital temperature sensor are sent to Acquisition Processor 10 by transmission cable with the temperature data and the ambient temperature data of the bearing that collects.Acquisition Processor 10 is connected with digital filter 40, it at first sends the temperature data of the bearing that receives and ambient temperature data to digital filter processor 40 and carries out Filtering Processing, Acquisition Processor 10 carries out the temperature over-range diagnosis according to the temperature data and the ambient temperature data of the bearing after the Filtering Processing then, sends bearing overtemperature alarm signal when being diagnosed as the bearing overtemperature.
In one embodiment, Acquisition Processor 10 can adopt multiframe slope dynamic diagnosis mode to carry out the temperature over-range diagnosis according to absolute temperature rise and relative temperature rise method, and is specific as follows:
The temperature value that sets in advance bearing is spent greater than 90 degree or greater than ambient temperature 45, and is alarm set point smaller or equal to 125 degree.
The definition frequency acquisition is that 5 seconds/time temperature sequence is: k (1), k (2), k (3) ... k (n) ...
Diagnosis algorithm is as follows:
(1) remove k (1) ... the noise spot on k (n) sequence:
If k (x)-k (x-1)＞5 and k (x+1)-k (x)＜-5 then k (x) is a noise spot;
If k (x)-k (x-1)＜-5 and k (x+1)-k (x)＞5 then k (x) is a noise spot;
(2) calculate k (1) ... the slope on k (n) sequence:
Slope K=(k (x)-k (x-1))/(t (x)-t (x-1)), t (x) is the sampling time that x is ordered,
When reaching alarm set point, if 0＜k＜=1 is defined as general overtemperature alarm;
When reaching alarm set point, if 1＜k＜=2 are defined as urgent overtemperature alarm;
When reaching alarm set point, if 2＜k＜=3 are defined as false alarm.
This is because the train bearing temperature belongs to slow variable, and the rising of temperature and decline need the process of a time, particularly to the such rigid body of spindle nose axle box.Therefore on the basis of accumulative total multiframe data, the slope relation between the dynamic calculation consecutive frame can effectively be removed interfering data and improve alarm rate, simultaneously can also be according to the tendency of slope, and the urgency level of prediction overtemperature alarm.
In one embodiment, LonWorks line of electric force network interface card 20 is used for the ambient temperature data in this compartment are mail to LonWorks line of electric force train communication network, and/or from the ambient temperature data of LonWorks line of electric force train communication network reception from other each compartments.When whether Acquisition Processor 10 adopts the relative temperature rise method diagnosis bearing temperature of aforementioned introduction to transfinite, can adopt the intermediate value of the ambient temperature of full array carriage to replace the ambient temperature in this compartment.This is because in existing diagnostic method, carry out relative temperature rise diagnosis according to the ambient temperature in bicycle railway carriage or compartment, yet under the influence of the installation site of the existing second type temperature sensor and bear vibration, open circuit often takes place or opens circuit in the second type temperature sensor, in case the therefore ambient temperature sensor failure in this compartment, the diagnosis of temperature rise method will lose foundation relatively.Adopt the mode of present embodiment then can avoid this problem effectively.
LonWorks line of electric force network interface card 20 also is used for bearing temperature data and/or bearing overtemperature alarm signal from described Acquisition Processor are mail to LonWorks line of electric force train communication network, and from bearing temperature data and/or the bearing overtemperature alarm signal of LonWorks line of electric force train communication network reception from other compartments.
Alternatively, Acquisition Processor 10 can send to the bearing temperature data in compartment compartment display 30 to show.Acquisition Processor 10 can also send the axle temperature transfinite alerting signal and carry out temperature alarming to compartment display 30 when diagnosing out excessive bearing temperature.
Alternatively, LonWorks line of electric force network interface card 20 also is used for sending bearing temperature data and/or bearing overtemperature alarm signal from other compartments to Acquisition Processor 10; Acquisition Processor 10 also is used to receive the bearing temperature data in other compartments and sends to compartment display 30 and carries out temperature alarming to show and/or to receive the bearing overtemperature alarm signal in other compartments and send to compartment display 30.
It is simple in structure that monitoring device of the present utility model is connected into LonWorks line of electric force train communication network.The pick-up unit in each compartment can automatic network-building, and requires low to communication media.By LonWorks line of electric force train communication network pick-up unit is carried out networking, can realize that any compartment can both monitor the bearing temperature of full array carriage, warning accuracy rate height.
Protection domain of the present utility model is not limited to disclosed specific embodiment in the above-mentioned embodiment, as long as but the combination of satisfying technical characterictic in the utility model claim just fallen within the protection domain of the present utility model.
