The utility model content
A purpose of the present utility model is, provide a kind of monitoring and in guideway vehicle, be used for the device of bearing temperature of bearing of guided-moving parts, this device can be determined the high hot running state of bearing reliably, it is overheated to that is to say, it is wherein, this that the cost of satisfactory overheated means of identification should be cheap aspect functional reliability.Another purpose of the present utility model is to provide a kind of method of monitoring bearing temperature and method that a kind of manufacturing is used for the device of monitoring bearing temperature of being used for accordingly.
In addition, according to a basic imagination of the present utility model, even bearing temperature means that not yet will bearing to occur malfunctioning, also can know bearing temperature.For example, the chaufeur of guideway vehicle can be read bearing temperature or slightly have when rising just to obtain warning signal at bearing temperature by the indicating device in the operator platform.Like this, chaufeur is based on experience, just can for example allow the people to bearing or movable parts examinations or maintenance in subsequently the chance.
But the utility model is thought, reliable especially in function aspects, not only can know continuously and process bearing temperature and can also when reach given criterion (reaching predetermined critical temperature such as bearing temperature), carry out or trigger the analytical calculation device of the respective behavior (such as the braking orbit vehicle) of being scheduled to, its cost is high especially.Particularly it is like this when this analytical calculation device that is used for continuous probe and treatment temperature observed reading is also born other monitoring and control task (as previously mentioned TCMS) in guideway vehicle.These other tasks for example comprise that monitoring and governing speed, control driving and brake system and recorded information are with as the basis of safeguarding guideway vehicle (namely diagnosis function).

In the heat indicator at least one for example can be known thermally dependent resistor, such as Pt100 type thermally dependent resistor.
For coolant-temperature switch different schemes is arranged also.Coolant-temperature switch for example can be the fusing insurance in principle, but different from traditional current fusing insurance, therefore traditional fusing insurance fusing when the electric current of pre-sizing is flowed through also makes and electrically contacts disconnection, and in the utility model, must guarantee only because of temperature or because the compound action of temperature and electric current just fuses.Another program for example is bimetal release, and this switch is opened when predetermined temperature owing to the different qualities of two kinds of metals or be closed.Preferred a kind of like this coolant-temperature switch, in this switch, but the first conducting element be connected with the first electric connection line, but and the second conducting element is connected with the second electric connection line.At this, the first and second elements or mechanically mutually pretension (Vorspannung) but do not exist electrically contact, perhaps be electrical contact with each other but such pretension mechanically not: this machinery pretension may make these elements disconnected from each other, causes electrically contacting disconnection.For this machinery pretension, the device that all can for example use in both cases a metal spring or some metal springs to form is such as the spirality metal spring.In both of these case, on off state and mechanical pretension by with a kind of when temperature raises fusing or the material that loses at least intensity keep.Paraffin is particularly useful for this purpose.If this material when overheated deliquescing and thereby can not continue to keep pretension, this pretension causes setting up and electrically contacts in the first situation so, that is to say switch closure, electrically contacts and cause disconnecting in the second situation, that is to say that electronic switch opens.
Utilize a kind of like this device to guarantee reliably, switch is opened when predetermined temperature or in the range of temperatures of being scheduled to or is closed.Therefore be no longer necessary for the function that realizes switch and the addition thereto that must continue at the guideway vehicle run duration enforcement.Compare with bimetal release, this switch can guarantee to have more failure-free function in long-time, because the material aging that the metal that forms the switch electric contact own does not occur along with time lapse affects switching function.For the function of switch, only utilized fusible material or the material behavior of the material of deliquescing when the temperature of expectation or in the range of temperatures of expectation, thereby no longer kept mechanical pretension and change its shape because of mechanical pretension.A kind of corresponding switch is for example by EPHY MESS(Gesellschaft f ü r elektrophysikalische
MbH, Wiesbaden, Deutschland) supply with title " fusible:T=xy ℃ of 2-wire circuit ".

According to the first scheme, the electron temperature detect switch of a plurality of sensors is connected in series in electricity, like this, by one of two or more switches because bearing temperature raises just to open circuit is disconnected.The second analytical calculation device is connected with this circuit and is designed to implement or trigger predefined action when this circuit disconnects.Owing to be connected in series in electricity, as long as unique second an analytical calculation device just is enough to implement or trigger predefined action when the on off state of a unique switch changes.Therefore, this function of this device more the failure-free scheme cost than a plurality of devices that have respectively second an analytical calculation device are designed function more may be required cost low.The second analytical calculation device itself can as unique one with the situation of the sensor of the electron temperature detect switch that is designed to circuit breaker under the design.
According to the alternative plan of the device with a plurality of sensors, the electron temperature detect switch of different sensors is connected in parallel, so that circuit is just closed when one of two or more switches are closed owing to bearing temperature raises.The second analytical calculation device is connected with this circuit and is designed to implement or trigger predefined action when this closing of circuit.For example apply the electric current that voltage and the second analytical calculation measurement device flow through at dead circuit after one of these circuit closure.Equally, as long as second an analytical calculation device just is enough to implement or trigger predefined action when the on off state of a unique switch changes.The second analytical calculation device itself equally can design as in the situation of unique sensor of an electron temperature detect switch that is designed to short circuiting switch (seeing above).
This structural unit especially can have two heat indicators, and wherein, the first analytical calculation device is designed to therein malfunctioning rear temperature of determining bearing by the observed reading of processing another heat indicator of heat indicator.Improved the reliability of sensor and can avoid for expending of emat sensor more by redundant heat indicator is set.
For example each heat indicator respectively have one independently electric connection line and these independently the electric connection line guide to one with switch that the first analytical calculation device links to each other on, like this, different according to the on off state of this switch, wherein one or another joint line are connected with this first analytical calculation device.Therefore, when a heat indicator is malfunctioning, can switch simply.
Alternatively, independently joint line and these heat indicators can also have a common electric connection line can to make each heat indicator have respectively one, wherein, these independently joint line for good and all be connected with the first analytical calculation device, thereby these heat indicators are being connected on the electricity on the first analytical calculation device, so in parallel, if two heat indicators can both be working properly, then they form less resistance, and if only have one can work in two heat indicators, the larger resistance of formation then.Therefore, the first analytical calculation device all can be processed and definite temperature measured temperature in both cases.
The first analytical calculation device especially can design like this: whether it identifies this heat indicator by the resistance of measuring the heat indicator that connects malfunctioning.Therefore, the first analytical calculation device can be automatically, the observed reading of analysis temperature meter correctly.
The first analytical calculation device is preferably designed to for identifying the malfunctioning rear generation of one of them heat indicator and exporting an interfering signal.

Fig. 7 schematically shows bear box 31, and this bear box for example is bear box 31 shown in Figure 3.Extend through a through hole of bear box 31 with the sensor 30 of two heat indicator 62a, 62b and an electron temperature detect switch 65.In Fig. 8, also show heat indicator 62a, the 62b and electronic switch 65 and their electric connection that are placed in these sensor 30 inside.Two temperature sensor 62a, 62b can optionally move, and that is to say only permission in two heat indicators 62 of a given time.For this reason, each heat indicator 62 has respectively one independently electric connection 91 and 93 and two heat indicators 62 has a shared electric connection 92.This moment as shown in Figure 7, two independently joint 91,93 guide a switch 97 into, thereby according to the difference of the switch position, wherein joint line 91 or another joint line 93 connect with the wire 98 that is connected that shares, and this connection wire is guided to the first analytical calculation device 88.Like this, at a given time, only have a job in two independent joint line 91,93, thereby also only have an operation among heat indicator 62a, the 62b.If in operational process, show, be in the characteristic that operating heat indicator 62 no longer sends believable observed reading or itself and temperature correlation change has occured, then can another heat indicator 62 be put into operation by change-over switch 97.Replace change-over switch, also can by other mode set up shared connection lead 98 with corresponding independently joint line 91,93 be connected, for example by socket connection being inserted or by welding.
In another particularly favourable scheme, two independently joint line 91,93 be not to guide on the switch 97, but (for example on the position shown in Figure 7 of switch 97) for good and all be electrically connected to each other, therefore also for good and all is connected on the shared connection wire 98.88 in the first analytical calculation device is design like this: it can be by the ohmage of measuring this device identifies actual temperature from the resistance value of the heat indicator 62a that is electrically connected in parallel and 62b or the resistance value that changes from the great-jump-forward of the heat indicator 62a that also works independently or 62b when one of these two heat indicators are malfunctioning.When a heat indicator 62 is malfunctioning, preferred the first analytical calculation device 88 changes generation and for example sends an interfering signal by the great-jump-forward of the resistance value of heat indicator, thereby can be in being connected to the message unit of back especially the indicating thermometer fault and/or in a fault memorizer recording thermometer fault, this memory device is read when handling labor usually.
The observed reading of the first analytical calculation device 88 treatment temperature meters 62 is also exported to corresponding observed reading central monitoring and the control system 89 of guideway vehicle.For example storage is used for determining the corresponding coefficient of temperature in the first analytical calculation device 88, and these coefficients are essential for the resistance value of the heat indicator 62 that is configured to temperature resistance is carried out analytical calculation.
In addition according to the utility model, integrated electron temperature detect switch 65 in sensor 30, this switch is connected on the second analytical calculation device 81 by joint line 94,95.The electric connection 94,95 of switch 65 is connected on the circuit 84, and the second analytical calculation device 81 also is arranged in this circuit, is used for the variation of on off state of search switch 65.For example in switch circuit 84, be provided with a voltage source 82 for this reason.The second analytical calculation device 81 is being connected to aspect the signalling technique in another system 83.If the second analytical calculation device 81 is determined: change (for example switch circuit 84 is disconnected by switch 65) has occured in the on off state of switch 65, then the second analytical calculation device 81 triggers a predefined action, this predefined action is implemented by system 83, and for example the braking orbit vehicle is until its parking.Because on electricity, be that control system 89 separate with the first analytical calculation device 88 and monitoring with the switch circuit 84 of the second analytical calculation device 81, can construct to such an extent that function is reliable especially by the device that switch 65, switch circuit 84 and the second analytical calculation device 81 and additional electrical block learn in case of necessity and member form, wherein, because function is simple, required expense is also very little for this reason.Therefore it is overheated to monitor reliably.
As previously mentioned, if exist a plurality ofly be used to monitoring overheated sensor, can make amendment to the circuit shown in Fig. 7 so.Also can be, in a unique sensor or a heat indicator only arranged in one of sensor.In this case, for example compare in of having saved in the joint line independently and the temperature resistance one with Fig. 7.
