Abstract
Description
Electronic braking indication system for at least one vehicle, particularly at least one railway vehicle. Technical field The present invention relates, in general, to the field of vehicles, for example, railway vehicles; in particular, the invention relates to an electronic braking indication system for at least one vehicle and to a vehicle comprising said electronic braking indication system. State of the art The state of the art will be described below with particular reference to the field of railway vehicles. However, what is described below may also be applied, where possible, to vehicles in other fields. Railway vehicles, whether intended for the transport of passengers or goods, usually have a pneumatic or electro-pneumatic braking system. This braking system comprises a brake pipe designed to carry a pressurized fluid and auxiliary tanks to store the compressed air. Various pneumatic or electro-pneumatic actuators installed along the vehicle are arranged to receive this fluid, through the respective pipes, and convert (in some cases even regulate) said pressure into a braking force that is applied to one or more disc pad and / or wheel shoe couplings. For multiple safety reasons and / or to support the monitoring of rolling stock, it is necessary to provide the vehicle with a system that allows the brake application status to be checked, as required, for example, by the European standard EN 15220. For example, for safety reasons, it is necessary to verify that if the driver has ordered the brakes to be released, the brakes have actually been released by all pneumatic or electro-pneumatic actuators. Failure to release the brakes by a pneumatic or electro-pneumatic actuator could lead to the dragging of the wheel or wheels associated with that actuator, resulting in damage to the rolling stock and infrastructure, and a risk of derailment. To carry out this type of check, known vehicles include brake indicators installed on the vehicle so that they are visible from the outside. Figure 1 illustrates an example of a 100 braking indicator according to the prior technique. In particular, the left side of Figure 1 shows the brake indicator in a released brake condition and the right side of Figure 1 shows the brake indicator in an applied brake condition. Each brake indicator is associated with one or more pneumatic or electro-pneumatic actuators and comprises a substantially box-shaped structure 102. Within structure 102, there is a plate 104 that is divided into two colors, C1 and C2, for example, green and red. The box-shaped structure includes an opening 106 through which a portion of plate 104 can be seen. If we look at the left side of Figure 1, when the braking force is released, i.e., when the pressure of the braking fluid 103 falls below a predetermined threshold, a predetermined elastic element 108 associated with plate 104 will hold the plate in a position such that the opening 106 of the box-shaped structure 102 reveals the portion of the plate that is color C1, i.e., green. Looking at the right side of Figure 1, when the braking force is applied, i.e., the brake fluid pressure is greater than a predetermined threshold, the predetermined elastic element 108 associated with plate 104 will be compressed so that plate 104 is in a position such that the opening 106 of the box-shaped structure shows the portion of the plate that has the color C2, i.e., red. When the vehicle is, for example, in a station or a sorting yard, before departure, the driver may release the brakes. Once the brake release command has been given, an operator outside the vehicle will check all brake indicators 100 and verify that the color C1, i.e., green, indicating brake release by the respective pneumatic or electro-pneumatic actuator(s), can be seen from the corresponding openings 106. If a brake indicator 100 displays the color C2, i.e., red, from opening 106, the operator will signal that a pneumatic or electro-pneumatic actuator has remained locked in a braking condition or, in any case, will indicate the presence of an anomaly. Today, the rail vehicle industry is undergoing a transition from pneumatic / electro-pneumatic braking systems to electromechanical braking systems. Unfortunately, the 100 brake indicators used for pneumatic / electro-pneumatic braking systems cannot be used for electromechanical braking systems. This is because the operation of the 101 brake indicators in pneumatic or electro-pneumatic braking systems was based on monitoring a brake fluid pressure value, which is no longer present in electromechanical braking systems. Examples of braking indication systems are provided in documents US 2016 / 076956 A1, DE 1951 104 A1, DE 7129540 U or DE 1282052 B. Summary of the invention Therefore, an object of the present invention is to provide a solution for electromechanical braking systems that produces visual information on the brake application status. The above and other objectives and advantages are achieved, according to one aspect of the invention, by means of an electronic braking indication system for at least one vehicle, particularly at least one railway vehicle, having the features defined in the respective independent claims 1 or 2, and by means of a vehicle having the features defined in claim 15. Preferred embodiments of the invention are defined in the dependent claims, the content of which is to be understood as an integral part of the present description. Brief description of the drawings The functional and structural characteristics of some preferred embodiments of an electronic braking indication system for at least one vehicle, particularly at least one railway vehicle, and of a vehicle according to the invention, will now be described. Reference is made to the accompanying drawings, in which: Fig. 1 illustrates a braking indicator according to the prior art; Fig. 2 illustrates an embodiment of an electronic braking indication system for at least one vehicle, particularly a railway vehicle, according to this invention; Fig. 3 illustrates an explanatory graphic as an example of the system operation showing an electronic braking indication system for at least one vehicle when only a first threshold is present; Fig. 4 illustrates an explanatory diagram as an example of the operation of the system showing an electronic braking indication system for at least one vehicle when a first threshold and a second threshold are present; Fig. 5 illustrates a further embodiment of an electronic braking indication system for at least one vehicle, particularly a railway vehicle, according to this invention; Fig. 6 illustrates a further embodiment of an electronic braking indication system for at least one vehicle, particularly a railway vehicle, according to this invention; Fig. 7 illustrates an electromechanical actuator according to the prior art. Detailed description Before describing in detail a plurality of embodiments of the invention, it should be clarified that the invention is not limited in its application to the design details and configuration of the components presented in the following description or illustrated in the drawings. The invention may assume other embodiments and be implemented or carried out in practice in different ways. It should also be understood that the phraseology and terminology are for descriptive purposes and should not be interpreted as restrictive. The use of "include" and "comprising" and variations thereof is intended to cover the elements presented below and their equivalents, as well as additional elements and their equivalents. With initial reference to Fig. 2, an embodiment of an electronic braking indication system for at least one vehicle, particularly a railway vehicle, is shown. The vehicle comprises at least one electromechanical actuator 202 arranged to apply a braking force F to at least one wheel W of the vehicle or to at least one braking element associated with at least one wheel W of the vehicle or an axle on which at least one wheel W of the vehicle is mounted. For example, the braking element, when associated with at least one wheel W of the vehicle, can be a wheel-mounted disc brake. For example, the at least one braking element, when associated with the axle on which the at least one wheel W is mounted, can be an axle-mounted disc brake. For example, the at least one electromechanical actuator 202, for applying the braking force F, may comprise braking force application means 203, such as, for example, a brake shoe, disc brake calipers, etc. The electronic braking indication system comprises at least one force sensor means 204 arranged to measure a value of said braking force F applied by said at least one electromechanical actuator 202. The value of said braking force may be, for example, the instantaneous value of the applied braking force F. The electronic braking indication system further comprises at least one electronic visual signaling device 206, comprising at least a first electronic light source 208 and at least a second electronic light source 210. Furthermore, the electronic braking indication system comprises at least 212 control means arranged to receive the measured value of said braking force F. For example, the at least one control means 212 may be or comprise at least one of a microprocessor, processor, microcontroller, controller, PLC, field-programmable gate array, or the like. In a first embodiment, the at least one control means are arranged to: a) switch on said first light source 208 when said measured value of the braking force F is less than a first threshold (indicated in Fig.3 as THRESHOLD 1); b) turn on said second light source 210 when said measured value of the braking force F is greater than said first threshold (THRESHOLD 1). Figure 3 illustrates an explanatory diagram as an example of the system operation showing an electronic braking indication system for at least one vehicle when only a first threshold is present, i.e., THRESHOLD 1. When the measured value of the braking force F is equal to the first threshold, the following control strategies can be applied interchangeably: The control means 212 are arranged to switch on said first light source 208; or The control means 212 are arranged to turn on said second light source 210. Or, when the measured value of the braking force F is equal to the first threshold, the control means 212 may be arranged to keep on the light source 208, 210 that was switched on before the first threshold THRESHOLD 1 was reached. In a second embodiment, as in the previous embodiment, the electronic braking indication system for at least one vehicle, particularly at least one railway vehicle, comprises at least one force-sensing means 204 arranged to measure a value of said braking force F applied by said at least one electromechanical actuator 202, at least one electronic visual signaling device 206 comprising at least one first electronic light source 208 and at least one second electronic light source 210. Unlike the first mode, at least one control means 212 are arranged to receive the measured value of said braking force F and: a) switch on said first electronic light source 208 when said measured value of the braking force F is less than or equal to a first threshold (indicated in Fig.4 as THRESHOLD 1); b) switching on said second electronic light source 210 when said measured value of the braking force F is greater than or equal to a second threshold (indicated in Figure 4 as THRESHOLD 2) different from said first threshold. Preferably, when both the first and second thresholds are present, the second threshold may be greater than said first threshold. Figure 4 illustrates an explanatory diagram as an example of the system's operation, showing an electronic brake indication system for at least one vehicle when a first and second threshold are present. With reference to Figure 4, a hysteresis range of I values can be created between the first threshold (THRESHOLD 1) and the second threshold (THRESHOLD 2). In the hysteresis band, the light source 208, 210 that was switched on before entering the hysteresis range I can remain switched on. In other words, if the measured braking force F is decreasing but has exceeded the second threshold (THRESHOLD 2) that triggered the activation of the second electronic light source 210, the at least one control means 212 can keep the second electronic light source 210 switched on until the measured braking force F has reached or fallen below the first threshold (THRESHOLD 1). Conversely, if the measured braking force F is increasing but has fallen below the first threshold (THRESHOLD 1) that triggered the activation of the first electronic light source 208, the at least one control means 212 can keep the first electronic light source 208 switched on until the measured braking force F reaches or exceeds the first threshold (THRESHOLD 1). For all the embodiments described, the at least one control means 212 could preferably be comprised in the at least one electromechanical actuator. In such a case, the control means 212 may be the control means usually installed in an electromechanical actuator to control its operation. Or, the at least one control means 212 may be additional suitable control means included in the electromechanical actuator. When a plurality of electromechanical actuators is present, each of them may comprise respective control means. In this case, there may be a plurality of control means 212, and a plurality of first electronic light sources 208 and second electronic light sources 210. Each control means may control the switching on of at least one respective first electronic light source 208 and at least one respective second electronic light source 210. Alternatively, and preferably, at least one control means 212 may be included in or associated with the electronic visual signaling device 206. For example, in this case, a single control means may be sufficient even in the case of a plurality of electromechanical actuators. The single control means of the electronic brake indication system may receive a plurality of brake force values F applied by the plurality of electromechanical actuators and control the switching on of all the first electronic light sources and all the second electronic light sources. When a plurality of electromechanical actuators is present, a plurality of force-sensing means 204 may also be present. Each of these may be arranged to measure a respective value of the braking force F applied by a respective electromechanical actuator. Each force-sensing means may comprise, for example, a force transducer or a force sensor. When a plurality of first electronic light sources 208 and second electronic light sources 210 are present, they may be installed in a single electronic visual signaling device 206, or they may be divided among several electronic visual signaling devices. Preferably, at least one electronic visual signaling device 206 may be installed on the vehicle so that at least one first electronic light source 208 and at least one second electronic light source 210 are visible from outside the vehicle. In this way, when the vehicle is, for example, at a station, before departure, the driver can release the brakes. Once the brake release command has been given, an operator positioned outside the vehicle will be responsible for observing all the first and second electronic light sources 208 and 210 and verifying that all the first electronic light sources 208 are illuminated and all the second electronic light sources 210 are de-energized (this condition being indicative of the brake release by all electromechanical actuators).If a second electronic light source 210 is on, even when the brake release command has been given by the driver, the operator may signal that an electromechanical actuator has remained locked in a braking condition or, in any case, he / she may signal the presence of an anomaly. Preferably, the measured value of the braking force F can be provided by at least one force sensor means 204 to at least one control means 212 via a communication channel 214. For example, as can be seen in Fig. 5, the communication channel 214 can be a wireless communication channel. In further embodiments, the communication channel 214 can be a permanently wired channel. Communication channel 214 can be based on the "black channel" protocol. Communication channel 214 can be implemented according to a Security Integrity Level (SIL) higher than a predetermined minimum Security Integrity Level. Preferably, as shown in Fig. 5, the electronic braking indication system for at least one vehicle may comprise first communication means 502 associated with said at least one force-sensing means 204. The first communication means may be arranged to allow the transmission / reception of signals on / from said communication channel 214. Furthermore, the electronic braking indication system for at least one vehicle may comprise second communication means 504 associated with said at least one control means 212 and arranged to allow the transmission / reception of signals on / from said communication channel 214. For example, the first 502 means of communication and the second 504 means of communication may each comprise at least one antenna. Preferably, the first communication means 502 associated with said at least one force sensor means 204 may be arranged to transmit a first signal indicative of the measured value of the braking force F continuously over time or according to a predetermined transmission period T. Preferably, when the vehicle is traveling at a speed less than or equal to a predetermined speed, the first communication means 502 associated with said at least one force sensor means 204 may be arranged to transmit to the second communication means 504, via said communication channel 214, a first signal indicative of the value of the braking force F continuously over time or according to a predetermined transmission period T. Preferably, at least one control means 212, via the second communication means 504, may send one or more signals indicating the on / off status of the first electrical light sources 208 and the second electronic light sources 210 to a remote control station or to an operator's user device. In this way, any maintenance required to repair any locked or malfunctioning electromechanical actuator can be more easily planned by the remote station personnel or by the operator equipped with a user device. Preferably, at least one control means 212 may be arranged to switch off at least one first electronic light source 208 and / or at least one second electronic light source 210 when the vehicle has reached or exceeded a predetermined speed. Alternatively, at least one control means 212 may be arranged to prevent the activation of said at least one first electronic light source 208 and / or said at least one second electronic light source 210 when the vehicle has reached or exceeded a predetermined speed. In other words, when the vehicle is traveling along a section at a speed exceeding a predetermined threshold, it is not necessary for at least one signaling device 206 to provide visual information regarding the release of the brakes, as there would be no operator able to see it.To save energy, at least one first electronic light source 208 and / or at least one second electronic light source 210 can be kept switched off. Preferably, as can be seen in Fig. 6, the at least one visual signaling device 206 may comprise first electronic light sources 208, 208', 208'' and second electronic light sources 210, 210', 210'' respectively for each electromechanical vehicle actuator 202, 202', 202''. For example, the various electronic light sources can be arranged in a checkerboard, matrix, or vector configuration. Preferably, each first electronic light source 208 may comprise at least one LED and / or each second electronic light source 210 may comprise at least one LED. In further embodiments, each first electronic light source 208 and / or each second electronic light source 210 may be implemented using additional technologies, for example, incandescent bulbs, neon lamps, or the like. Preferably, the at least one electronic visual signaling device 206 may comprise a circuit board on which the first electronic light source 208 and / or the second electronic light source 210 may be installed (also, all first electronic light sources 208 and / or all second electronic light sources, when present, may be installed on said circuit board). Preferably, the at least one electronic visual signaling device 206 may further comprise a logic circuit arranged to implement a predetermined control logic. In one example of control logic, the vehicle may comprise a plurality of electromechanical actuators 202, for example, four electromechanical actuators arranged to apply respective braking forces F to four different wheels W of the vehicle or to four braking elements, each associated with at least one wheel W of the vehicle or with four axles on which wheels are mounted. The four wheels, or the four braking elements, or the four axles, may be included, for example, in the same bogie of the vehicle. For each electromechanical actuator present, the at least one electronic visual signaling device 206 may comprise a respective first electronic light source 208 and a respective second electronic light source 210. In the present example, since there are four electromechanical actuators, the at least one electronic visual signaling device may comprise four first electronic light sources and four second electronic light sources. By means of the logic circuit, it is possible, for example, to enable the switching on of all the second electronic light sources when at least one control means commands the switching on of a second electronic light source because the electromechanical actuator (associated with this second electronic light source) has applied a braking force greater than the first threshold THRESHOLD 1 (or the second threshold THRESHOLD 2, when present).This control logic allows, for example, better identification of the bogie that is having a brake release problem due to its own electromechanical actuator. Clearly, different control logics can also be implemented compared to the one just described. For example, the logic circuit can include one or more logic gates. Alternatively, when control means 212 are included in an electronic visual signaling device 206, it can take charge of implementing control logic itself. Preferably, the electronic braking indication system may comprise a suitable battery arranged to supply electrical power to at least one electronic visual signaling device 206, to at least one first electronic light source 208 (e.g., to each first electronic light source present) and to at least one second electronic light source (e.g., to each second electronic light source present). Or, the at least one electronic visual signaling device, the at least one first electronic light source (e.g., each first electronic light source present) and the at least one second electronic light source (e.g., each second electronic light source present) may be arranged to receive electrical power directly from a vehicle battery. An example of a possible electromechanical actuator is provided below. With reference to Fig. 7, an illustrative embodiment of a prior art electromechanical braking actuator 700 is shown. The electromechanical actuator may comprise a first electromechanical module 701 which may comprise at least one electric motor and possibly a speed reducer, i.e., torque multiplier, which can extend or retract an arm 706 connected to an emergency braking module 707. The emergency braking module 707 may comprise emergency braking energy storage means 708, for example, mechanical means for storing potential mechanical energy. The mechanical means for storing potential mechanical energy include, but are not limited to, a helical spring. The emergency braking module 707 may further comprise emergency braking energy release means 709, for example, an electromechanical holding mechanism controlled by an emergency braking request signal 710. The emergency braking energy release means 709 may be arranged to have a first state in which they retain the potential mechanical energy previously stored in the emergency braking energy storage means 708 when the emergency braking request signal 710 does not indicate an emergency braking request.Emergency braking energy release means 709 are arranged to have a second state in which they release the potential mechanical energy previously stored in emergency braking energy storage means 708 when emergency braking request signal 710 indicates an emergency braking request. Other forms of mechanical energy storage can be used, such as, but not limited to, a flat coil spring when the force transfer is rotational rather than translational. Furthermore, the stored energy can be kinetic energy stored in a flywheel kept in proper rotation by a second motor, not shown in the figure. The force sensor 204 of the electronic brake indication system for at least one vehicle, which is the subject of the present invention, may be restricted, for example, to an arm 711 (the force sensor is indicated by reference number 712 in Fig. 7). The force sensor may generate an electrical signal 713 indicative of the braking force. This signal may be indicative of the mechanical force applied between arms 711 and 714. The electrical signal 713, in addition to being supplied to the control means of the electronic brake indication system for at least one vehicle, which is the subject of the present invention, may be fed into a service brake control unit 702. An arm 714 may be connected between the force-sensing means 712 and a slack recuperator 715 that transmits the force to a final arm 716 connected to the brake pad support assembly 717 plus brake pad. The slack recuperator 715 is intended to continuously recover wear on the brake pad. Brake pad wear may also be recovered by means of software procedures performed by the control unit, such procedures not being covered by this invention. The 702 service brake control unit, which is electronic in nature, can receive at its input a 705 power supply voltage that does not originate exclusively from the vehicle's battery. The service brake control unit 702 may be arranged to modulate the supply voltage 705 to control the electric motor included in the electromechanical module 701 via at least one electrical control signal 704. The service brake control unit 702 may receive an input signal indicating a service brake force request 703 and may be arranged to apply a service brake force corresponding to that service brake force request 703 by controlling the electromechanical module 701 to extend the arm 706 until the electrical signal 713 indicating brake force shows that the brake force corresponding to the service brake force request 703 has been reached. It is known that the connection sequence in which modules 701, 707, 712, 715 are connected can change according to design and manufacturing convenience. The electromechanical actuator 700 described above is provided only as an example and is just one of the possible electromechanical actuators that can be associated with the electronic brake indication system for at least one vehicle, which is the subject of the present invention. The present invention is, in fact, applicable to any type of electromechanical actuator. The following are example descriptions of respective braking indication methods for at least one vehicle. In the first example, the method comprises the following steps: measure a braking force value F applied by at least one electromechanical actuator of the vehicle 202 to at least one wheel W of the vehicle or to at least one braking element associated with at least one wheel W of the vehicle or to an axle on which at least one wheel W is mounted; to switch on a first electronic light source 208, e.g., of an electronic visual signaling device 206, when said measured value of the braking force F is less than a first threshold (THRESHOLD 1); switch on a second electronic light source 210, e.g., from the electronic visual signaling device 206, when the measured value of the braking force F is greater than said first threshold (THRESHOLD 1). In a second example, the method comprises the following steps: measure a braking force value F applied by at least one electromechanical actuator of the vehicle 202 to at least one wheel W of the vehicle or to at least one braking element associated with at least one wheel W of the vehicle or to an axle on which at least one wheel W is mounted; to switch on a first electronic light source 208, e.g., of an electronic visual signaling device 206, when said measured value of the braking force F is less than or equal to a first threshold (THRESHOLD 1); switch on a second electronic light source 210, e.g., from the electronic visual signaling device 206, when said measured value of the braking force F is greater than or equal to a second threshold (THRESHOLD 2) different from said first threshold (THRESHOLD 1). The methods mentioned above can be implemented using at least one control device or computer. The embodiments described above for the electronic brake indication system for at least one vehicle, where possible, are also applicable to the methods described above by way of example. Furthermore, in a further aspect, the present invention relates to a vehicle. The vehicle comprises at least one electromechanical actuator 202 arranged to apply a braking force F to at least one wheel W of the vehicle or to at least one braking element associated with at least one wheel W of the vehicle or to an axle on which at least one wheel W of the vehicle is mounted. The vehicle further comprises an electronic braking indication system according to any of the embodiments described above. The present invention is applicable to at least one vehicle. Therefore, the present invention also applies to a plurality of vehicles; for example, it may be applicable to a plurality of vehicles connected together to form a convoy, for example, a railway vehicle convoy. As described above, the present invention is particularly applicable to the field of railway vehicles / trains traveling on railway tracks. For example, a vehicle referred to herein may be a locomotive or a railcar, and a route / section may include rails on which the locomotive's wheels roll. The embodiments described herein are not intended to be limited to rail vehicles. For example, the vehicle may be a car, a truck (e.g., a semi-trailer truck, a mining truck, a timber truck, or the like), and the route may be a road or a track. For example, a train may comprise a plurality of such vehicles connected or associated with one another. Various aspects and embodiments of an electronic braking indication system for at least one vehicle, particularly at least one railway vehicle, and of a vehicle according to the invention, have been described. It is understood that each embodiment can be combined with any other embodiment. Furthermore, the invention is not limited to the described embodiments but can be varied within the scope defined by the appended claims.
