Description

Title of the invention: Method for processing railway traffic fault data using a control box. Technical field

[0001] The present invention relates to a method for processing, by a control unit, data relating to faults occurring during the operation of railway vehicles, stored in a plurality of memory cards arranged in a monitoring unit. It also relates to a control unit implementing such a method.

[0002] The field of the invention is the railway field, and more particularly the field of memory card management in monitoring devices relating to faults occurring during train traffic. State of the art

[0003] Railway vehicles are often equipped with a monitoring unit, also called a dual-standard drawer, which stores faults occurring during vehicle operation. When there are too many faults, the memory that records them becomes saturated, hindering the proper functioning of the monitoring unit and sometimes rendering it unavailable. To prevent the monitoring units from becoming unavailable due to a large number of stored faults, it is necessary to regularly clear the faults recorded in their memory.

[0004] In addition, test trains and test benches are also equipped with these monitoring units. At the end of testing with these benches or trains, it is also useful to read the faults stored in the monitoring units before clearing them. The aim is to study these faults, particularly in order to resolve them.

[0005] Various methods and devices implementing these processes are known, enabling the reading and erasure of faults recorded in these monitoring devices. These methods and devices are functional but present several problems, including: - implementation challenges because they require removing a memory card from the monitoring device under study, or because they require connecting numerous cables specific to each memory card in the monitoring device. - speed of execution because they require the repetition of different steps for each memory card individually, and - clutter caused by heavy and bulky devices requiring numerous connections.

[0006] One object of the invention is to remedy at least one of the aforementioned drawbacks.

[0013] Another aim of the invention is to propose a method enabling memory management of a fault monitoring device that is more automated and therefore simpler to implement. Another aim of the invention is to offer a faster execution method. Description of the invention The invention makes it possible to achieve at least one of the aforementioned goals by a method of processing data relating to defects occurring during the movement of railway vehicles, stored in a plurality of memory cards arranged in a monitoring box, said method implementing a control box, characterized in that it comprises a connection of said control box to said monitoring box, and a data processing phase comprising the following operations: - triggering the initialization of multiple memory cards by powering on the monitoring unit, - a manual connection command for one or more memory cards to the control box, based on at least one connection data communicated by each of the memory cards to said control box following said triggering step, - a manual control of a processing state of at least one of the connected cards by control of a relay of said connected card. The method according to the invention thus provides a processing method in which all connected cards can be controlled following the manual connection command operation, and across the plurality of memory cards included in the monitoring unit. In this way, the method according to the invention can process and control several memory cards simultaneously or not. This avoids repeating the entire processing phase individually for each memory card in the monitoring unit. The method according to the invention is therefore more efficient and faster to implement, as it requires fewer repetitions of the various operations, resulting in time savings compared to the prior art method. Furthermore, the method according to the invention requires less manual handling. It is therefore also simpler to implement because it does not require, for example, the repetition of numerous connections between the control box and the monitoring box to operate and process several memory cards in the monitoring box. A data processing state of a memory card can be a state of reading the data stored in said card.

[0014] The method according to the invention thus makes it possible to control the reading of files contained on one or more connected memory cards located in the monitoring unit. The method according to the invention is therefore faster because it is not necessary to remove or connect each memory card from the monitoring device. The processing can be directly managed and controlled externally to the monitoring unit, in particular simply by connecting the control unit to the monitoring unit.

[0015] A data processing state of a memory card can be a data read and erase state triggering the deletion of data stored in said memory card.

[0016] The method according to the invention thus makes it possible to read and erase data contained in several connected memory cards by linking the control unit to the monitoring unit. The method according to the invention therefore offers a simple and inexpensive way to manage the memory cards of the monitoring device in order to prevent its saturation.

[0017] A data processing state of a memory card can be a state of reading the data stored in said memory card, said method may further include a selection and storage of at least a part of the data read in the control box.

[0018] The method according to the invention makes it possible to select data of interest from among the data read and to save this data of interest for subsequent analysis carried out, for example, by an operator. Thus, it is possible to achieve better management of the faults recorded by the monitoring device in order to quickly identify their causes and resolve them more rapidly.

[0019] The data processing phase may include an operation to select one or more memory cards before the initialization operation.

[0020] The selection operation can be manual or automatic.

[0021] The method may include an identification of the data processed during the data processing phase, by using an identification data arranged to identify said memory card, said identification data being previously recorded in said monitoring box, or in the memory card.

[0022] The manual connection command of at least two memory cards can be carried out at different times depending on the reception by the control box of the connection data emitted by each of the memory cards.

[0023] The method according to the invention can therefore process several memory cards at different times within the same processing phase iteration. In this way, the method according to the invention adapts to different types of memory cards that are not connected simultaneously. The method according to the invention can therefore process several memory cards at separate time intervals. The method according to the invention is therefore more flexible.

[0024] The data processing phase of the process according to the invention may include, for at least one memory card, a time window of at least 0.5 seconds, preferably between 1 and 5 seconds, starting from an emission, by said memory card, of the connection data, and during which the manual connection command of said memory card to the control box may be carried out.

[0025] The method according to the invention thus allows a short delay (during the time window) to connect the memory card(s) to the control box. This manual connection operation saves time because wired connections for each card are avoided.

[0026] When the time windows of at least one of two memory cards have an overlap period, then the manual connection command operation for each of these two memory cards can be performed simultaneously during said overlap period.

[0027] The method according to the invention thus makes it possible to connect and therefore simultaneously control several memory cards when their time windows overlap, at least partially. Such a method can therefore connect and control several memory cards simultaneously, even if they are initialized at different times, which avoids repeating the processing phase for each of the memory cards.

[0028] When the time windows of at least one of the two memory cards do not have an overlapping period, then the manual connection command operation of these two memory cards can be performed in turn.

[0029] Thus, if memory cards do not include an overlap of their time window, then the method according to the invention connects and controls the memory cards alternately.

[0030] The manual connection control operation and / or manual control of the process according to the invention can be engaged manually on the control box or via an electronic device connected to the control box by wire or wireless means.

[0031] In this way, the process according to the invention can, for example, be controlled remotely and automatically. It is therefore no longer necessary to have an operator on site, which increases efficiency and also reduces costs.

[0032] The manual connection control operation and / or manual control of the method according to the invention can be carried out by wireless or wired connections, which allows it to adapt to different types of monitoring devices. The method according to the invention is therefore more flexible to implement for different types of monitoring devices, without constraints related to the type of monitoring device being processed.

[0033] The manual connection control operation and / or manual control can This procedure can also be performed directly on the control unit, which can be useful in case of a malfunction in the monitoring unit requiring operator intervention. In this way, the process can be carried out directly on-site by an operator.

[0034] The data processing phase of the process according to the invention may include a display and / or visualization of the data stored in at least one of the memory cards on a display means integrated into said control box or connected to said control box.

[0035] In this way, the method according to the invention allows for the visualization of data stored in the connected memory cards. This visualization allows for a visual assessment of the data and facilitates, for example, the selection of data of interest from the multitude of data recorded in a particular memory card.

[0036] The method according to the invention may include an identification of the data read and / or stored via a configuration file of said control box.

[0037] The data processing phase of the process according to the invention may include a visualization of the progress of said process by an indicator so as to display the operations carried out and / or being carried out and / or those not carried out or to come and / or the defects occurring in said process.

[0038] Thus, it is possible to monitor the progress of the process in order to carry out checks in a simple, quick and inexpensive way.

[0039] This indicator can be visual or audible depending on the need.

[0040] This indicator can be viewed directly at the control box or remotely, adapting to different control boxes or different connections or wiring of the control box to the monitoring box and its integration into a railway control system.

[0041] For example, the indicator may include at least one indicator light positioned on the control box and / or at least one indicator light on a software interface of the control box and / or of an external electronic device such as a control computer.

[0042] This at least one indicator light can therefore provide information on malfunctions of said control box or of the process according to the invention by specifically targeting the operations within the process according to the invention that are malfunctioning. This simplifies troubleshooting because the operator can directly target the sources of the problems.

[0043] The step of connecting the control box to the monitoring box can be carried out when said monitoring box is off, and in particular only when the monitoring box is off.

[0044] The method according to the invention is safer and thus limits the risks damage to either the control box and / or the monitoring box, or to the memory cards located in the monitoring box.

[0045] The data stored in the plurality of memory cards may include log files.

[0046] The method according to the invention can therefore read or read and erase data contained in information files commonly used for data recording.

[0047] The method according to the invention may include a connection of the control box to an external device via a port provided on said control box.

[0048] Said external device may be arranged to power the control box, and / or communicate with said control box. The external device may include: - a display means, and / or - a storage medium for storing stored data, and / or - a means of control via a human-machine interface to control said control box.

[0049] The method according to the invention can therefore be adapted to be controlled remotely or on-site by an external device connected to the control box. It is then possible to use the human-machine interface of the external device in the implementation of the method according to the invention, which offers greater flexibility.

[0050] According to another aspect of the invention, a control unit is proposed, arranged to process data relating to faults occurring during the operation of railway vehicles, stored in a plurality of memory cards arranged in a monitoring unit, said control unit comprising: - a first connection port to connect said control box to said monitoring box, and - an electronic card; arranged to implement a process according to the invention.

[0051] The control box according to the invention can implement the method according to the invention in a simple way because it only requires physically connecting the control box according to the invention to the monitoring box.

[0052] Since the control box according to the invention requires fewer connections and therefore less wiring, the control box according to the invention is thus less bulky, more compact and lighter. It is, therefore, easier to transport.

[0053] The control box according to the invention is also made from standard components, making it easy to implement and inexpensive. Component replacement is also facilitated.

[0054] The control box according to the invention makes it possible to obtain advantages similar to those developed for the process according to the invention because it is arranged to put it in artwork.

[0055] The control box according to the invention may include: - indicator lights arranged to visualize the progress of the treatment phase, and / or - a second connection port arranged to allow for the removable insertion of a storage element into said control box, and / or - an external power supply arranged to provide power to said control box.

[0056] In this context, the control unit according to the invention does not require the use of a computer to operate. The control unit according to the invention can therefore operate autonomously. The control unit according to the invention is therefore also easily transportable.

[0057] The control box according to the invention may include: - a switch arranged to power on said control box, and / or, - at least one login button arranged to launch an operation of manual connection command for one or more memory cards to the control box, and / or - at least one actuation button arranged to initiate a manual control operation of a processing state of at least one memory card.

[0058] The control box according to the invention thus comprises means necessary for powering said box and means for controlling it. The control box according to the invention is therefore easy to use.

[0059] The control box may include: - a first activation button to initiate the manual control operation related to data reading, and - two buttons, the first button being to activate the manual operation related to reading and erasing, and the second button to confirm said processing operation to initiate the operation, and / or - a button to initiate the manual operation for deleting the data stored on said memory card, and / or - a lever arranged to engage the manual control operation relating to the selection and storage of at least part of the data read in said control box.

[0060] The control box according to the invention can therefore include all the elements enabling the various commands and / or operations of the process according to the invention to be initiated. The control box according to the invention is therefore directly controllable at starting from said control box. The use of the control box according to the invention is therefore simple.

[0061] The control box according to the invention may include a third connection port for connecting said control box with an electronic device arranged to power and / or communicate with said control box, said electronic device comprising: - display means to show the status or progress of said process, and / or - a control means via a human machine interface to control said control box.

[0062] The control unit according to the invention can therefore be adapted to be controlled remotely or on-site by a computer connected to said control unit. The control unit according to the invention is compatible and adaptable with a multitude of control tools. It is therefore easier to implement. Brief description of the drawings

[0063] Other advantages and features of the invention will become apparent from the detailed description of implementations and embodiments, which are by no means limiting, and the following attached drawings. [fig.l] Fig.l is a non-limiting schematic representation of an example of an embodiment of the process according to the invention; [fig.2] Fig.2 is a non-limiting schematic representation of a first example of the realization of a control box according to the invention, said control box implementing a method according to the invention; [Fig. 3] Figure 3 is a non-limiting schematic representation of a second embodiment of a control box according to the invention, said control box implementing a method according to the invention; and [fig.4] Fig.4 is a first non-limiting example of a first mode of operation of the treatment phase of the process according to the invention; [fig.5] Fig.5 is a second non-limiting example of a second mode of operation of the treatment phase of the process according to the invention; Detailed description of the figures

[0064] It is understood that the embodiments described below are in no way limiting. In particular, variants of the invention may be conceived comprising only a selection of the features described below, isolated from the other features described, if this selection of features is sufficient to confer a technical advantage or to differentiate the invention from the prior art. This selection includes at least one preferably functional feature without structural detail, or with only some of the details. structural if that part alone is sufficient to confer a technical advantage or to differentiate the invention from the prior art.

[0065] In particular, all the variants and all the embodiments described are combinable with each other if nothing prevents this combination from a technical point of view.

[0066] In the figures, the elements common to several figures retain the same reference.

[0067] Fig. 1 is a schematic representation of a non-limiting example of an embodiment of a method according to the invention.

[0068] Method 100 is a method for processing data relating to faults occurring during the operation of railway vehicles, stored in a plurality of memory cards arranged in a monitoring unit. Method 100 implements a control unit (the plurality of memory cards, the monitoring unit, and the control unit are illustrated in Figures 2 and 3).

[0069] The method 100 includes a connection 102 from the control box to the monitoring box.

[0070] The process 100 further includes a data processing phase 104.

[0071] The data processing phase 104 comprises at least three operations corresponding to: - triggering an initialization 106 of the plurality of memory cards by powering on the monitoring unit, - a manual connection command 108 of one or more memory cards based on at least one connection data communicated by each of the memory cards to said control unit following said initialization triggering step 106, - a manual control 110 of a processing state of at least one of the connected cards by control of a relay of said connected card.

[0072] The data processing state of a connected memory card includes, at choice: - a read state 112 of the data stored in said connected memory card. - a read and erase state 114 of data triggering a read and then a deletion of the data stored in said connected memory card. In this way, process 100 allows the memory of connected memory cards to be erased in a simple way.

[0073] Furthermore, the manual command operation 110 can be performed on several connected memory cards. This manual command operation 110 can also be performed simultaneously on the connected memory cards or at different times on the connected memory cards. In this way, the method 100 avoids repetition from the data processing phase 104 to each of the memory cards of the monitoring unit to be processed. Process 100 can therefore process all the memory cards of the monitoring device in a shorter time.

[0074] When the data processing state is a read state 112 of the data stored in said connected memory card, the method 100 may also include a selection and storage 116 of at least a portion of the data read in the control unit. The data contained in the connected memory cards is then erased to clear the memory of the monitoring unit. In this way, some of the read data is selected for saving for later analysis.

[0075] The selection operation alone (not illustrated) can also be combined with the data read and erase state 114. In this way, only selected data can be erased in order to retain the other read data. This unerased data can then be studied by an operator to understand the origin of stored defects and find solutions to correct them.

[0076] The connection step 102 of the control box to the monitoring box is carried out when said monitoring box is off.

[0077] The manual connection command operation 108 corresponds to an action by the operator on said control box or on a human machine interface linked to the control box after the emission, by one or more memory cards, of the connection data.

[0078] The method 100 includes an identification of the data processed during the data processing phase 104, by using an identification data arranged to identify said memory card, said identification data being previously recorded in said monitoring box, or in the memory card.

[0079] In an alternative embodiment of the method 100, not shown, the data processing phase 104 includes a selection operation of one or more memory cards before the initialization operation 106. In this way, an operator can select the memory cards of interest before the start of the data processing phase 104. This operation can be performed by the operator via a manual command on the control unit or via a human-machine interface linked to the control unit.

[0080] Fig. 2 is a non-limiting schematic representation of a first example of an embodiment of a control box 202 according to the invention, said control box 202 is arranged to implement the method 100 according to the invention.

[0081] The control unit 202 is arranged to process data relating to faults occurring during the operation of railway vehicles. These faults are stored in the plurality of memory cards 206 arranged in the monitoring unit 204.

[0082] The control box 202 includes: - a first connection port 212 to connect said control box 202 to said monitoring box 204, and - an electronic card 210.

[0083] The monitoring unit 204 is for example positioned in a railway vehicle or along a railway track (not illustrated).

[0084] The monitoring unit 204 includes at least one connection port 214.

[0085] The control box 202 is connected to the monitoring box 204 by a Wired connection 216 by connecting the connection port 212 of the control box 202 to the connection port 214 of the monitoring box 204. In this case, the connection of the control box 202 can be made by an operator in the railway vehicle in which the monitoring box 204 is positioned.

[0086] In an unillustrated variant, the monitoring unit 204 includes two connection ports 214. For example, the connection between the monitoring unit 204 and the control unit 202 is made by a Y-shaped cable 216 with the two branches of the Y connected to the two connection ports 214 of the monitoring unit 204. The data or signals exchanged between the monitoring unit 204 and the control unit 202 can be distributed across the two connection ports 214.

[0087] The monitoring unit 204 further comprises a plurality of memory cards 206. The monitoring unit 204 comprises at least one memory card 218, 220, 222, 224, 225 in which the data is recorded. In the case of [Fig. 1], the monitoring unit 204 comprises five memory cards 218, 220, 222, 224, 225. The data stored in the memory cards 218, 220, 222, 224, 225 are different, in particular indicating different information. For example, memory card 218 is a TIU card. Memory card 220 is a CORE card. Memory card 222 is a CPBI memory card. Card 224 is an RTM card, and card 225 is an ODO card. The difference between the 218, 220, 222, 224, and 225 memory cards lies in the source of the information. For example, the ODO 225 memory card stores speed information from the train vehicle's speed sensors.In addition, some memory cards initialize faster than others. In particular, their initialization speed may differ depending on the version of the 202 monitoring unit. Memory cards 218, 220, 222, 224, and 225, for example, can store IMO of data.

[0088] The data stored in the plurality of memory cards 206 include Log files.

[0089] Optionally, the control box 202 includes an ON / OFF switch 211 arranged to turn on said control box 202.

[0090] In the case shown in [fig.2], the control box 202 is not autonomous; it is connected to an electronic device 203 via a third port 205 of the control box. Control unit 202 and port 207 of electronic device 203. In an alternative configuration (not shown), the connection between control unit 202 and electronic device 203 can be wireless. This allows for remote control of the connection between control unit 202 and electronic device 203, thus reducing the number of connections required. Electronic device 203 is equipped with a processor or computing board (not shown) to initiate and / or command instructions to control unit 202 via the electronic board 210 of control unit 202. Electronic device 203 is therefore a computer 203 or a tablet 203 if the latter has a USB port. Electronic device 203 is configured to power the control unit (5-volt power supply).

[0091] The electronic device 203 comprises: - display means (not illustrated), such as a screen, to display the status or progress of process 100, - a storage medium (not shown), for storing memorized data, and - a means of control (not illustrated) via a human machine interface to control said control box 202 via the electronic card 210. The storage medium for electronic device 203 can be either the device's own memory card or an external hard drive connected to computer 203. This allows for easy transport of the data stored on the hard drive. In an alternative configuration (not shown), the control unit 202 may include a removable memory card for data storage. The display means is also arranged to display or visualize the data stored in the plurality of connected 206 memory cards, and also to display the selection and storage of data.

[0092] The manual connection command operation 108 and manual command operation 110 are triggered by an operator's action on the control box 202 and / or the human-machine interface. For example, the operator can press a separate or combined button arranged to perform these commands 108 and 110 directly on the control box 202 and / or the human-machine interface.

[0093] The human-machine interface is a software interface (not illustrated) installed on said electronic device 203.

[0094] In order to control the control box 202, the human-machine interface of the computer 203 may include: - an actuation button to initiate manual operation 110 related to data reading, and - a button to initiate manual operation 110 relating to reading and erasing, which may also include a second button to confirm said manual operation 110 to activate the operation, and / or - a button to activate manual operation 110 relating to the deletion of data stored in said memory card 218, 220, and / or - a button to activate the manual connection command operation 108 of one or more memory cards to said control box 202, and / or - a button to choose the destination for the data to be saved, and / or - a mouse and a button arranged to trigger the command operation manual 110 relating to the selection and storage of at least part of the data read in said control box 202.

[0095] Optionally, the human-machine interface includes at least one indicator light arranged to visualize the progress of the processing phase 104. This visualization allows the display of operations carried out and / or being carried out and / or those not carried out or to come and / or defects occurring in said process.

[0096] For example, the human-machine interface includes four indicator lights. These indicator lights include: - a green LED arranged to indicate that the control box 202 is receiving power correctly, - a red LED arranged to warn of a fault occurring in said process 100 or to highlight a malfunction of said control box 202, - a blue LED to indicate the ongoing processing of a manual control operation 110 of a processing status and / or the manual connection control operation 108 of one or more memory cards 206 in the control box 202, - an orange LED indicating successful completion of command operation 110 in one of the memory cards 206. In this case, the control unit includes five orange LEDs arranged to indicate the progress of processing phase 104 for each of the connected memory cards 218, 220, 222, 224, and 225. The human-machine interface can therefore display one indicator light per connected memory card.

[0097] Thus, in the case considered, only the red LED allows an error or malfunction to be reported in the data processing phase 104. For example, the management of errors or malfunctions with the indicator lights is as follows.

[0098] If the red LED is off, then processing step 100 is working correctly. However, if the red LED is on, then an error is present in processing step 100. In this case, the orange LED should be checked to determine at which step the error was detected. If no orange LED is on, then this means there is a fault in the connection between the control unit 202 and the monitoring unit 204, for example, at the wired connection 216 linking connection port 212 of control unit 202 to connection port 214 of monitoring unit 204. If several orange LEDs are lit, simply consider the orange LED following the last one lit to determine which card caused the fault. An orange LED only lights up when the data processing phase 104 has been successful. For example, the operator can initiate manual command operation 110 when the blue LED is off after sending the manual connection command 108 for one or more memory cards via control unit 202, particularly when an operator presses the button to initiate manual connection command operation 108 of control unit 202 and / or the human-machine interface.

[0099] The human-machine interface therefore allows control of the control box 202, in particular the electronic board 210 of the control box 202 in order to implement the process 100, in particular the treatment phase 104 of the process 100.

[0100] These indicator lights can provide information on malfunctions of the control unit 202 or of process 100 by individually targeting malfunctioning elements or steps of process 100. Troubleshooting is therefore simplified because the operator directly targets the source of the problem.

[0101] In an alternative, not shown, the control box 202 may include: - a first actuation button to initiate the manual control operation 110 relating to a data reading, and - two push buttons, the first push button being to initiate manual operation 110 relating to reading and erasing, and the second push button to confirm said manual operation to initiate the operation, and / or - a button to initiate manual operation 110 relating to the deletion of data stored in said memory card (218, 220), and / or - a button to activate the manual connection command operation 108 of one or more memory cards to said control box 202, and / or - a control lever arranged to activate the manual control operation 110 relating to the selection and storage of at least a portion of the data read from said control unit 202. The control lever is, for example, in the form of a lever and buttons arranged to navigate through the list of read data, to choose a starting and ending point allowing the selection of different data from a list of read data, and to confirm the data selection. The control lever is also arranged to choose the destination of the data to be saved. In this case, the user can initiate the manual control operation 110 of a data processing state directly from the previously mentioned buttons on the control box 202 or via the human-machine interface.

[0102] The method 100 includes, in a variant of the method, an operation of selecting, via the control box 202 or the human machine interface, one or more memory cards before the initialization operation 106.

[0103] By way of example, the control unit 202 includes a configuration file that specifies which memory card will transmit the connection data first, or whether it should monitor the memory cards 206, for example, those that have been selected, simultaneously. Thus, the control unit 202 is configured to distinguish a memory card by selecting its assigned physical connection. Routing is performed within the control unit 202 to address the correct memory card in the monitoring unit 204. The configuration file may include identification data arranged to individually identify each memory card. The configuration file is therefore structured to implement the identification of the data processed on each of the memory cards connected to said control unit 202.For example, the identification data corresponding to the CORE 220 memory card includes at least the string CORE in its identification data, whereas the TIU memory card includes at least the string TIU.

[0104] Fig. 3 is a non-limiting schematic representation of a second example of an embodiment of a control box 302 according to the invention, said control box 302 is arranged to implement the method 100 according to the invention.

[0105] The monitoring unit 204 and the control unit 302 of [Fig. 3] include all the elements of the monitoring unit 204 and the control unit 202 of [Fig. 2]. Thus, only the differences with the control unit 202 of [Fig. 2] will be described.

[0106] The control unit 302 includes display means 304, a screen 304, arranged to display and / or view the data stored in the plurality of connected memory cards 206. The display means 304 is positioned on said control unit 302. The display means is also arranged to display the selection and storage 116 of the data.

[0107] The control box 302 also includes means arranged for visualizing the progress of said process 100 implemented by the control box 302. These means include an indicator 306 arranged to display the operations performed and / or being performed and / or those not performed or to come and / or the faults occurring in said process 100. This indicator 306 may be a visual indicator or audible. In the case of [Fig. 3], the indicator is visual, it is a light indicator.

[0108] The control unit 202 further comprises: - a first activation button to initiate manual control operation 110 related to data reading, and - two pushbuttons, the first pushbutton being to initiate manual operation 110 relating to reading and erasing, and the second pushbutton to confirm said manual operation 110 to initiate the operation, and / or - a button to initiate manual operation 110 relating to the deletion of data stored in said memory card (218, 220), and / or - a control lever arranged to activate the manual control operation 110 relating to the selection and storage of at least a portion of the data read from said control unit 202. The control lever is, for example, in the form of a lever and buttons arranged to navigate through the list of read data, to choose a starting and ending point allowing the selection of different data from a list of read data, and to confirm the data selection. The control lever is also arranged to choose the destination of the data to be saved.

[0109] The control unit 302 thus includes at least one indicator light arranged to visualize the progress of the processing phase 104. In particular, the control unit 302 includes eight indicator lights. The indicator lights are LEDs positioned on the front face of the control unit 302. In the case of [Fig. 1], the control unit 302 includes, for example: - a green LED 308 arranged to light up to indicate that the control box 302 is properly powered, - a red LED 310 arranged to light up to indicate the presence of a fault occurring in said process 100 or to highlight a malfunction of said control box 302, - a blue LED 312 arranged to light up to indicate the ongoing processing of a manual control operation 110 of a processing state and / or the ongoing processing of the manual connection control operation 108 of one or more memory cards in said control box 302, - five orange LEDs 316 to display a progress status of the processing of a manual command operation 110 in one of the connected memory cards 218, 220, 222, 224, 225. In the case of [fig.3], the control box 302 includes, for example, five orange LEDs 316 (not all shown) arranged to indicate a progress status of the processing phase 104 for each of the memory cards 218, 220, 222, 224, 225.

[0110] In addition, the control box 302 illustrated in [fig.3] includes an external power supply 318 arranged to supply power to said control box 302. The external power supply 318 is an external battery 318. In this way, particularly when the control box 302 is operating on battery 318, it is self-contained, in the sense that it does not need to be connected to an additional electronic device to operate, for example to power itself.

[0111] The control box 302 in the context of standalone use (i.e. without PC) includes at least one button to perform the operations of said data processing phase 104. The control box 302 thus includes the ON / OFF switch 211 to power the said control box 302. The control box 302 also includes a first push button 320 arranged to trigger the initialization 106 of the plurality of memory cards 206 included in the control box 302, via the electronic card 210 to the monitoring box 204. This first push button 320 is also arranged to trigger the manual connection command operation 108 of one or more memory cards to said control box 302. The control box 302 also includes a second push button 322 arranged to implement the manual control 110 of a read-only state 112 of all the data stored in the memory cards 218, 220, 222, 224, 225 connected following the manual connection control operation 108.

[0112] The control box 302 also includes an actuation zone 324 arranged to implement the manual control 110 of a read and erase state 114 of the data triggering a read and then a deletion of the data stored in the memory cards 218, 220, 222, 224, 225 connected with the control box 302 following the manual connection control operation 108. The actuation zone 324 consists in particular of a third push button 326 to control the read and erase state 114 and a fourth push button 328 for the confirmation of the processing state. In this way, the control box 302 limits the operator's actions to connecting (i.e., plugging) the control box 302 to the monitoring unit 204, and pressing the various buttons to initiate the initialization operation 106, the manual connection command 108, and the manual command 110 of a processing state by choosing between a data read request 112 or a data read and erase request 114. The control box 302 is therefore easily operated. An operator can also control process 100 very simply. In a variant of the control box 302, it is not necessary for the control box 302 to include a button to trigger the initialization operation 106. Indeed, the latter can be triggered automatically by switching on the control box 302 after the connection step 102.

[0113] The control box 302 may include a joystick (not shown) arranged to trigger the selection and storage operation 116 of at least a portion of the data read in said control box 302. The joystick is for example in the form of a manual lever and buttons arranged to move through the list of data read, to choose a starting point and an end point allowing the selection of different data in a list of data read, and to confirm the data selection.

[0114] The control unit 302 includes a second connection port 330 arranged to removably accommodate a storage element (not shown) within said control unit 302. This storage element is arranged to store at least a portion of the data read from the control unit 302. The storage element may be a removable memory card, a USB flash drive, or an external hard drive arranged to connect removably via the second connection port. Thus, the portion of the data read but not erased (i.e., because it is saved in the removable storage element) can be examined by an operator to understand the origin of the stored defects and find solutions to correct them. It should be noted that the control unit according to the invention may also include a second connection port 330 to accommodate the storage element when operating with an electronic device 203 as illustrated in [Fig. 2].In this way, it is possible to have a single version of the 202 or 302 control box that can adapt to different needs, i.e., standalone or non-standalone use (e.g., when using an electronic device 203).

[0115] The electronic card 210 is arranged to implement the process 100, in particular to control all the operations of the treatment phase 104 of the process 100 and all the different components positioned in the control box 302.

[0116] Fig. 4 is a non-limiting example of an operating mode of the treatment phase 104 of the process 100 according to the invention.

[0117] In particular, [Fig. 4] illustrates the data processing phase 104 of two memory cards 218 and 220 of the monitoring unit 204. Memory card 220 is a CORE card and memory card 218 is a TIU card. For example, the selection operation was performed via the control unit 202, 302 to select the CORE memory card 220 and the TIU memory card 218.

[0118] Curve 401 illustrates an operating characteristic of the processing phase of the CORE 220 memory card. Curve 402 illustrates a characteristic of the operation of the processing phase of the TIU 218 memory card. Characteristics 401 and 402 are in the form of a square wave signal.

[0119] The control unit 202, 302 is always powered before the monitoring unit 204. The data processing phase 104 begins automatically with the triggering of the initialization 106 by powering up the monitoring unit 204 at time t = 0 seconds (s). This power-up is performed either manually using switch 211 or via a human-machine interface. The initialization 106 is indicated by the low state of characteristics 401, 402 of the CORE 220 and TIU 118 memory cards. After a certain time, specific to each of the CORE 220 and TIU 218 cards, characteristics 401, 402 of the 220 and 118 memory cards will transition to a high state 403.

[0120] Memory cards 218, 220 go to high state 403, which corresponds to a state where memory cards 218, 220 are waiting for a signal, i.e. waiting for a manual connection command 108, following the sending (or transmission) 409 of the connection data.

[0121] The connection data transmitted by each of the memory cards 220, 218 comprises at least one string of characters. For example, the string received when the card is ready to be connected is "Waiting for 5 seconds". The time indicated in the connection data is that of a time window 404 during which the connection operation 108 of the memory card 218 or 220 can be performed. This string of characters is associated with the memory card 218, 220 that transmits the connection data. The connection data associated with the memory card is displayed on the display means of the control unit 202, 302 and / or on the human-machine interface. In an alternative embodiment not shown, the connection data may be an audible signal, and / or a visual signal, and / or comprise a sequence of one or more strings of characters and / or symbols and / or numbers.

[0122] The high-state slot time 403 is the time window 404 of at least 0.5 seconds, preferably between 1 and 5 seconds, starting from the transmission of the connection data, and during which the manual connection command 108 of said memory card can be executed. In the case illustrated in [Fig. 4], the time window 404 is five seconds for the CORE 220 and TIU 218 memory cards. Thus, the manual connection command 108 of the memory cards 220 and 218 via the control box 202, 302 can be executed during the time when the characteristics 401, 402 of each card 220, 218 transition to the high state 403 following the transmission of connection data by each of the memory cards 220 and 218.

[0123] In the case of [Fig. 4], the CORE 220 memory card initializes faster because the connection data of the CORE 220 memory card is emitted before that of the TIU 218 memory card. The CORE 220 memory card's time window 404 occurs before that of the TIU 218 memory card. In particular, there is approximately a four-second difference between the 404 time window of the CORE 220 memory card and the TIU 218 memory card. However, both the CORE 220 and TIU 218 memory cards have an overlap 406 of their 404 time windows. During this 406 overlap (time range), the 404 time windows of both the CORE 220 and TIU 218 memory cards are open. The 406 overlap is, for example, one second. It can, of course, vary from 0.5 seconds to 5 seconds depending on the type of memory card: TIU, CORE, CPBI, RTM, ODO. The 406 overlap can, for example, occur throughout the entire 404 time windows of the TIU 218 and CORE 220 memory cards. In this latter case, it means that the 218 and 220 memory cards were initialized simultaneously. Of course, the 406 overlap can occur at any point within the 404 time window.

[0124] The overlap 406 of the time windows 404 of the CORE 220 and TIU 218 memory cards allows the two memory cards 218, 220 to be connected simultaneously with the control box 202, 302, which then allows the manual control operation 110 of the processing state of the two CORE 220 and TIU 218 memory cards to be engaged simultaneously, for example when the operator presses a button arranged to engage the manual control operation 110. If there is no overlap 406 (i.e. no superposition of high state), the method according to the invention can monitor the two memory cards at the same time to allow the connection signal to be sent to each memory card alternately (this variant of the method is illustrated in [fig.5]).

[0125] The overlap 406 lasts for 1 second in [Fig. 4] and represents the possibility of initiating a manual connection command 108 on both memory cards 218, 220 simultaneously. Thus, the overlap period 406 corresponds to a time delay during which the operator can simultaneously activate the manual connection command 108 on both memory cards 218, 220. The manual connection command 108 corresponds to an action by the user via the control unit 202, 302 or the human-machine interface to control the connection of the memory cards 218, 220 with the control unit 202, 302. In this example, this common window cannot be less than 0.5 seconds due to the relay switching time. In particular, the manual connection command 108 is effective when a signal is sent to the memory cards 218, 220 via the control box 202, 302.During the overlap period 406 of the time windows 404, the method 100 includes the emission of a first signal, for example a light, indicating to an operator that he can connect the control box 202, 302 to the two memory cards CORE 220 and TIU 218. For example, the operator can. Press the connection button on control unit 202, 302 after control unit 202, 302 emits this first signal. After this manual connection command 108, the operator can initiate manual control operation 110 when a second signal, for example, a light, is emitted by control unit 202, 302. Thus, manual connection command 108 and manual control operation 110 of both memory cards 218, 220 are performed simultaneously, avoiding the need to repeat these actions for each memory card 218, 220. The overlap 406 cannot be less than 0.5 seconds due to the relay switching time.

[0126] The simultaneous activation of the manual connection command operation 108 during the overlap period 406 is achieved by switching the input and output ports connecting the electronic board 210 to the connected memory cards CORE 220 and TIU 218. For example, the activation of the manual command 110 is achieved by the control unit 202, 302 setting to 0 Volts the signals connected to pins 1 to 6 of the CORE card connector located on the monitoring unit 204. This switching can only occur after the completion of the manual connection command operation 108 of the TIU 218 memory card during the overlap period 406; otherwise, the manual command operation 110 of the TIU 218 memory card would not be taken into account (because the TIU 218 memory card would not have connected). via the electronic card 210 of the control box 202, 302).The electronic board 210 of the control box 202, 302 can only control connected memory cards. Thus, in the case of [fig.4], the idea of ​​the method 100 is to monitor the reception of the connection data of the memory card which takes the longest to initialize and upon receipt of this connection data, to switch all the necessary wires, via the relay in a minimum time, for example in 0.5 seconds, to carry out the manual connection command 108 and then the manual command 110 of a read processing state 112 or a read and erase state 114.

[0127] The time window 404 ends when the signal passes into a low state 408. Two possibilities arise.

[0128] If the manual connection command 108 was sent to the control unit 202, 302 during the time window 404, then the manual control operation 110 of a processing state can be performed during the period in the low state 408. For example, the user can press the read or read and erase button located on the control unit 202, 302, which will initiate the reading or read and erase of the data stored in the memory cards 218, 220. Thus, in this case, this low state 408 corresponds to a mode where the memory card-control unit connection is operational to perform the manual control operation 110 of a read-only processing state 112 or in read and erase mode 114.

[0129] If no manual connection command 108 has been sent to the control box 202, 302 during the time window 404, particularly during the overlap period when it is desired to act on several memory cards at the same time, then the initialization operation 106 restarts during the low state period 408.

[0130] The processing state can thus be either reading only 112 of the data or reading and erasing 114 of the data contained in the two connected CORE 220 and TIU 218 memory cards. The selected processing state can also be accompanied by the selection and storage 116 of at least a portion of the data read from the control unit 202, 302. The signal indicating that the manual control operation 110 can be initiated is, for example, in the form of an indicator as described in Figures 3 and 4. The signal is emitted automatically without human intervention. The indicator informs the operator whether the control unit 202, 302 is connected to the memory card(s) 218, 220 or not. This indicator can be visual, in the form of an indicator light positioned on the control unit 302, or displayed on a human-machine interface.This indicator can also be in the form of a message displayed on the control box 302 display or on the human-machine interface. The indicator can also be audible.

[0131] The data read by the control box 202, 302 can be saved either on an electronic device 203 connected to the control box 202, 302 and / or on a removable memory card of the control box 202, 302. The recorded data is identified by an identifier, for example, a string of characters that associates the read and saved data with the memory card from which it is extracted. For example, data read and saved from a CORE 220 memory card includes at least the string "CORE" in its identifier, while a TIU 218 memory card includes at least the string "TIU" in its identifier. Thus, the data read and saved from each type of memory card is uniquely identified. The control unit 202 or 302, after reading the data, adds this information to the data backups to facilitate operator understanding. The identifier can also include other information, such as the card number.The identification data, including the character string, was previously recorded in the said control box 202, 302 via the configuration file.

[0132] Figure 5 is a non-limiting example of one operating mode of the treatment phase 104 of the process 100 according to the invention. Only the differences with Figure 4 will be described.

[0133] In this embodiment, two memory cards 220 and 218 of the monitoring unit 204 are shown. Memory card 218 is a TIU card and memory card 220 is a CORE card.

[0134] Curve 502 illustrates the operating characteristic of the processing phase 104 of the CORE 220 memory card.

[0135] Curve 501 illustrates the operating characteristic of the processing phase 104 of the TIU 118 memory card.

[0136] Curve 504 illustrates the operating characteristic of the relay during the processing phase 104.

[0137] Curve 506 illustrates the operating principle of a listening port (not shown in Figures 2 and 3) positioned in the control box 202, 302.

[0138] Fig. 5 illustrates a case where none of the memory cards 220, 218 of the monitoring unit 204 includes an overlap 406 of the time windows 404. In this case, the control unit 202, 302 is provided with at least one listening port arranged to alternately monitor the reception of at least one connection data communicated by each of the memory cards 220, 218 to said control unit 202, 302 following the triggering step 106.

[0139] In the case illustrated in [Fig. 5], the listening port is connected to the microcontroller 210. It is configured to alternately monitor the connection data of, for example, two predefined types of memory cards. In the illustrated case, the listening port alternately monitors the TIU 218 memory card and the CORE 220 memory card. The control unit 202, 302 can have as many listening ports as there are memory cards in the monitoring unit. In our case, the connection data monitored by the listening port is predefined. It can be modified by an operator at any time, particularly after the control unit 202, 302 is connected to the monitoring unit 204. In a variant not shown, the listening port may be configured to alternately monitor more than two memory cards.

[0140] The 506 curve operates alternately and includes a square wave signal, also called a listening window. Thus, when the 506 characteristic of the listening port is high, the listening port monitors the reception of at least one connection data signal from the TIU 118 memory card. When the 506 characteristic of the listening port is low, the listening port monitors the reception of at least one connection data signal from the CORE 220 memory card. The monitoring of the connection data from a memory card is at least 0.5 seconds, preferably between one and five seconds. The control unit 202, 302 must be powered on before the monitoring unit 204 in order not to miss the connection data transmitted by one of the cards during the listening window. Preferably, the monitoring of the data from The connection time is less than 5 seconds to verify whether the two memory cards 218 and 220 share a common slot (overlap period 406, illustrated in [Fig. 4]). The listening time must be long enough to receive the connection data, for example, the message "Waiting for 5 seconds," and short enough not to miss an overlap period (as illustrated in [Fig. 4]). Typically, the listening time is 0.5 seconds. On feature 506, the timing of the listening slots is fixed. If no connection data is detected and after a delay of 60 seconds, a connection error is declared and the connection operation is inhibited.

[0141] The data processing phase 104 starts automatically by triggering the initialization 106 by switching on the monitoring box 204 at time t = 0 second (s).

[0142] Initialization 106 is materialized by the low state of the characteristic of the CORE 220 and TIU 118 memory cards. After a certain time, specific to each card 220, 218, the characteristic of the memory cards 220 and 118 will switch to a first high state 403.

[0143] As long as no memory card 220 or 218 has been connected, the alternate listening of the listening port is maintained. However, at time t = A, the listening port receives a connection data signal from the TIU 218 memory card. At this instant A, the characteristic of the memory card 218 transitions to a first high state 403 following the transmission 409 of the connection data. The time window 404 of the TIU 218 memory card begins. A manual connection command 108 is sent via the control unit 202, 302 to the TIU 218 memory card. The microcontroller of the control unit 202, 302 commands the relay to close. Switching the relay initiates the connection operation 110. The manual connection command operation 108 can be initiated within the time frame of the time window 404. The time window 404 corresponds to a timing duration 404.In particular, the time delay 404 corresponds to the delay between the transmission of the connection data in the form of the message "Waiting for 5 seconds" and the detection of pins 1 to 6 of the CORE card at the 0 volt point of the control box 202, 302 following the manual connection command 108. At the end of the time window 404 (end of the time delay), the characteristic of the detected memory card 218 passes into a second high state 503, higher than the first high state 403. The memory card is therefore connected to the control box 202, 302. The control box 202 is therefore ready to initiate the read-only processing state 112 or the read and erase state 114.

[0144] The relay opens after the memory card 218 enters its second high state 503, that is, when the memory card 218 is connected to the control unit 202, 302. The control unit 202, 302 is therefore able to trigger the command of a TIU memory card processing status.

[0145] When a TIU 118 memory card has been identified by the listening port via the transmission of its connection data, the listening port subsequently monitors the connection data of the not yet identified memory card 220 via its connection data, here the CORE 220 card. For this reason, the characteristic of the listening port remains in its low state, i.e. on the listening port of the connection data of the not yet identified memory card 220.

[0146] In the same way as for the previously identified TIU 118 memory card, at time t = B, the connection data 409 is transmitted by the TIU 218 memory card. At this instant B, the characteristic of the memory card 220 transitions to a first high state 403. The listening port receives connection data from the CORE 220 memory card. As before, a manual connection command 108 is sent via the control unit 202, 302 to the CORE 220 memory card by the operator's action on the control unit 202, 302 or on the human-machine interface. The microcontroller of the control unit 202, 302 commands the closing of the relay. The second high state 503 corresponds to the connected state of the CORE 220 memory card. The manual command operation 110 can be launched in this second high state 503.

[0147] The execution of the manual control operation 110 can begin when the detected memory card characteristic 220 passes into a second high state 503, higher than the first high state 403, i.e. when the CORE memory card 220 is connected to the control box 202, 302.

[0148] The relay remains in its closed position throughout the operation of controlling the processing state of the last connected memory card 220. In an alternative embodiment not shown, the relay can return to its open position. Maintaining the relay in a high state after the memory cards are connected helps to limit the power consumption of the control unit 202, 303 in order to improve battery life. However, the relay must be open before any manual connection control operation (when the control unit 202, 302 is powered on).

[0149] Thus, [fig.5] illustrates the manual connection command 108 and the manual control 110 of two memory cards 218, 220 engaged at different times.

[0150] Of course, the invention is not limited to the examples just described. Many modifications can be made to these examples without departing from the scope of the present invention as described.
