Detailed description of the invention
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The bogie truck lock shaft fault monitoring method diagram of circuit that Fig. 1 provides for the embodiment of the present invention one.As shown in Figure 1, the bogie truck lock shaft fault monitoring method that the embodiment of the present invention provides, comprising:
S101: the mode of operation of bogie truck on monitoring train.
Concrete, along with the operation of train, the continuous friction of bogie truck and wheel, bogie truck and wheel there will be damage, make bogie truck can there is axle non rotating fault, also i.e. bogie truck lock shaft fault, bogie truck when making train operation non rotating, train normally cannot travel along train rail, causes harmful effect to the safe in operation of train.Therefore, the mode of operation of monitoring bogie truck is needed, to guarantee train traffic safety.By the mode of operation of bogie truck on the monitoring module monitors train in bogie truck lock shaft fault monitoring device in the embodiment of the present invention, wherein, the mode of operation of monitoring bogie truck comprises: monitoring bogie truck is in normal operating condition, is still in lock shaft faulty condition.
(WheelSlideProtection can be protected by wheel skid in the embodiment of the present invention; be called for short WSP) mode of operation of device monitoring bogie truck; also can by non rotating axle detection (NonRotatingAxisDetection; be called for short DNRA) mode of operation of device monitoring bogie truck; can adopt the mode of operation of WSP device and DNRA device monitoring bogie truck, the embodiment of the present invention does not carry out limiting and repeating at this simultaneously yet.Concrete, WSP device and DNRA device monitoring bogie truck mode of operation realize principle and WSP device in prior art and DNRA device monitoring bogie truck mode of operation to realize principle identical, the embodiment of the present invention does not repeat at this.
It should be noted that, bogie truck is positioned at the foot of train, is between train body and track, in order to traction with move and lead train and travel along train rail, is the critical component of safe train operation.
S102: judge whether bogie truck exists lock shaft fault.If bogie truck exists lock shaft fault, then perform S103; Otherwise, perform S101.
Concrete, the mode of operation of the bogie truck that the judge module in bogie truck lock shaft fault monitoring device arrives according to monitoring module monitors, judges whether bogie truck exists lock shaft fault.For example, when monitoring modular passes through the mode of operation of WSP device monitoring bogie truck, if bogie truck exists lock shaft fault, WSP device monitors the lock shaft fault of bogie truck by the speed sensor of WSP device, and reporting control unit, judge module monitors bogie truck and there is lock shaft fault.When monitoring modular passes through the mode of operation of DNRA device monitoring bogie truck, if there is lock shaft fault in bogie truck, DNRA device monitors the lock shaft fault of bogie truck by the speed sensor of DNRA device, and reports control unit, and judge module monitors bogie truck and there is lock shaft fault.When monitoring modular monitors the mode of operation of bogie truck by WSP device and DNRA device simultaneously, if there is lock shaft fault in bogie truck, WSP device and DNRA device monitor the lock shaft fault of bogie truck simultaneously, and report control unit, and judge module monitors bogie truck and there is lock shaft fault.
S103: rolling test is carried out to bogie truck.If monitor bogie truck rolling test to pass through, then perform S104; Otherwise, perform S105.
Concrete, when judging that bogie truck exists lock shaft fault, the control module in bogie truck lock shaft fault monitoring device carries out rolling test to bogie truck.
Wherein, test is rolled for monitor the rate of change of bogie truck at train moving process medium velocity in Preset Time; If bogie truck is less than or equal to the first predetermined threshold value at the rate of change of train moving process medium velocity, then rolling test is passed through, otherwise test of rolling is not passed through.
It should be noted that, test of rolling is by being that larger change can not occur the percentage speed variation of bogie truck in train moving process.For example, bogie truck may accelerated movement before this in train moving process, and then uniform movement, as long as bogie truck, at accelerated movement medium velocity, larger change does not occur, just can think that bogie truck is in stabilized conditions in train moving process, bogie truck rolling test is passed through.Or, bogie truck also may accelerated movement before this in train moving process, and then decelerated movement, as long as there is not larger change at accelerator medium velocity in bogie truck, there is not larger change at moderating process medium velocity, can think that bogie truck is in stabilized conditions in train moving process yet yet.It should be noted that, the Preset Time that the embodiment of the present invention provides specifically can be determined according to the distance of the speed of bogie truck in train moving process and train movement, such as, if the speed of bogie truck in train moving process, the distance of train movement is shorter, then can arrange less Preset Time; If the speed of bogie truck in train moving process is comparatively slow, train miles of relative movement is longer, then can arrange larger Preset Time.The first predetermined threshold value that the embodiment of the present invention provides specifically can be determined according to the distance of train movement on bogie truck, and such as, train miles of relative movement is longer, then can arrange the first larger predetermined threshold value.Also can determining according to the environment on train road surface in moving process, such as, if road surface has certain gradient, then by arranging the first larger predetermined threshold value, if road surface is more smooth, then the first less predetermined threshold value can be set.Concrete arranging of first predetermined threshold value is determined according to actual environment, and the embodiment of the present invention does not limit at this.

Concrete, if control module monitors bogie truck rolling, test is passed through, then determine that bogie truck does not exist lock shaft fault, and may be that the speed sensor of WSP device or DNRA device breaks down, now, ignore the lock shaft fault of bogie truck, control train and continue normal operation.
S105: determine that bogie truck exists lock shaft fault, controls Train Stopping.
Concrete, if control module monitors bogie truck rolling, test is not passed through, then determine that bogie truck exists lock shaft fault, control Train Stopping.
The bogie truck lock shaft fault monitoring method that the embodiment of the present invention provides, by the mode of operation of bogie truck on monitoring train, judge whether bogie truck exists lock shaft fault, if there is lock shaft fault in bogie truck, then rolling test is carried out to bogie truck, if monitor bogie truck rolling test to pass through, then ignore the lock shaft fault of bogie truck, control train and continue normal operation; If monitor bogie truck rolling test not pass through, then determine that bogie truck exists lock shaft fault, control Train Stopping.Monitoring after bogie truck exists lock shaft fault, rolling test is carried out to the bogie truck that there is lock shaft fault, further bogie truck is tested, again judge to determine whether bogie truck normally works, improve the accuracy that bogie truck exists lock shaft malfunction monitoring, ensure the safety of train travel.
