Description

Technical Field

[0001] The invention relates to a decoder for a match timing system. The invention further relates to a match timing system for detecting a passing sports timing transponder during a sport event. Background Art

[0002] In the field of timing of sports events, such as running, marathon, cycling, ski races, car races, horse races or other events, timing the start, finish and split timing points of the participants plays an important role. In the popular timing systems, the person, vehicle or animal whose time is to be measured carries a radio element (sports timing transponder, in particular an active or passive RFID tag) for contactless automatic timing. For example, runners can carry radio elements that are attached to shoelaces or to a bib number to be pinned on the participant's shirt or pants.

[0003] At the start, finish and split timing locations along the track, measuring points are installed to detect the presence of a radio element and determine the elapsed time, i.e. the moment when the radio element passes the measuring point. To this end, the measuring point usually comprises corresponding antennas and data processing means to process the received data. Usually, the determined participant elapsed times are then transmitted to a central evaluation point for access by the event organizers and participants.

[0004] In this case, a transponder specifically designates a radio element that is able to transmit and receive radio signals. A transponder can refer to a passive RFID tag without an integrated energy source or to an active RFID tag with a built-in battery. In the case of a passive RFID tag, the transponder is usually activated, i.e. read out, when passing a measuring point by a corresponding RFID reader, which can determine the elapsed time based on one or more readings. In the case of an active RFID tag, an induction loop is usually detected by the tag and the elapsed time is calculated in the tag based on multiple detections in order to transmit the elapsed time to a corresponding device for further processing and / or evaluation.

[0005] Current sports timing systems for passive RFID tags usually consist of a suitcase-sized device, often called a decoder, which includes an RFID reader. The decoder is connected to a corresponding RFID antenna. The antenna is usually a ground antenna integrated in a cable channel or a side antenna located on a tripod on the side of the track. In addition to the RFID reader, which is usually an RFID reader originally used for logistics applications, current decoders include at least a battery, a processing module and different options for communication.

[0006] In this context, EP 3 832 520 A1 relates to a device for determining the elapsed time of a passive RFID sports timing transponder, comprising: a housing for protecting the device from environmental influences; an RFID reader unit connected to the RFID antenna for remotely determining the identification and elapsed time of the sports timing transponder when the sports timing transponder passes the device; a location unit for determining the location of the device; a mobile communication unit connected to the mobile communication antenna for transmitting the identification and elapsed time of the sports timing transponder and the location of the device to a remote processing unit; and a neighbor communication unit for communicating with another similar device in the immediate spatial vicinity to synchronize the operation of the RFID reader unit and the RFID reader unit of the other similar device to avoid interference, wherein the RFID reader unit, the RFID antenna, the location unit, the mobile communication unit and the neighbor communication unit are integrated in a common printed circuit board mounted in the housing. The invention also relates to a system for timing sports events.

[0007] A related drawback of current solutions is that they are generally limited in flexibility with respect to the different requirements of different events. Typically, timekeepers, i.e., those who provide timing services, require hardware that can be used in different application scenarios. Specifically, some events utilize active RFID tags, while other events utilize passive RFID tags. In addition, the start, end, and split timing locations are usually not known in advance, so flexible installation is required. The width of the track may be different and may not be known in advance. In addition, quick and easy installation is required at the venue of the sporting event. Therefore, the system is usually installed by unskilled workers who have no or little specific experience, so simple installation is essential. In addition, since the usual application scenario is outdoors, it is important that weather conditions such as high or low temperatures, rain or sunshine do not hinder the application of the timing system. Summary of the invention

[0008] In view of the above, the present invention solves the problem of providing a solution for timing matches that is robust, flexible in use and simple to install. In particular, it is desirable to provide a decoder that can operate in outdoor conditions and that provides a high degree of flexibility with respect to the different requirements of different sports events. Furthermore, it is desirable to provide a simple and comfortable match timing system.

[0009] In order to solve this problem, a first aspect of the present invention relates to a decoder for a game timing system, comprising:

[0010] - a reader interface for receiving detection of a sports timing transponder passing by an antenna;

[0011] - Cable connection interface, used to connect network cables and / or computer interface cables;

[0012] - A user interface for providing configuration feedback to the user;

[0013] - a processing unit for determining the elapsed time of a participant in a sporting event based on the detection; and

[0014] - a housing for protecting the processing unit from environmental influences, wherein

[0015] - The user interface is arranged on the outside of the housing for providing user access, and the cable connection interface is arranged under the protective cover, which is configured to provide user access to the cable connection interface in an open state and protect the cable connection from environmental influences in a closed state.

[0016] In another aspect, the present invention relates to a game timing system, comprising:

[0017] - a decoder as described above, and

[0018] a detection assembly comprising an antenna and a computing unit connected to the antenna, said antenna and computing unit being positioned in the channel element, wherein

[0019] - The computing unit comprises an RFID reader circuit.

[0020] Preferred embodiments of the invention are defined in the dependent claims. It shall be understood that the claimed match timing system has similar and / or identical preferred embodiments as the claimed decoder, in particular as defined in the dependent claims and disclosed herein.

[0021] The invention is based on the idea of ​​combining an externally arranged and permanently accessible user interface with a cable connection interface, which is arranged under a protective cover to be protected from environmental influences. Thus, a network cable and / or a computer interface cable can be connected to the decoder via a conventional plug. It is not necessary to use a connector suitable for outdoor operation and resistant to water and other impacts. Typically, users at a sports event want to use their conventional equipment to connect to the decoder and further process the detection.

[0022] A reader interface allows the decoder to be connected to a device for detecting sports timing transponders. A cable connection interface allows the decoder to be connected to a computer network or a computer to establish a connection for further processing of the detection. A user interface is provided to provide configuration feedback to the user. For example, the user may be provided with information related to the current detection, or information related to configuration parameters of the decoder or a device connected to the decoder. The processing unit of the decoder is housed in a housing so as to be protected from environmental influences such as rain, splashing water, sunlight, dust, etc.

[0023] Compared with the previous method in which both the cable connection interface and the user interface are arranged under the protective cover, the decoder of the present invention provides better usability. In particular, under adverse environmental conditions such as rain or snow or other situations, malfunctions caused by water entering the decoder housing through one of the connecting cables are prevented. The reliability of the match timing system is improved. It is ensured that the decoder and the match timing system can be used in all weather conditions. In addition, the decoder in the match timing system can be operated simply and safely, which also enables unskilled workers to provide timing services.

[0024] In an embodiment, the reader interface includes a passive RFID connector for connecting to an RFID reader circuit connected to an antenna and for receiving detection of a passive transponder from the RFID reader circuit. The antenna does not constitute part of the decoder. The passive RFID connector preferably corresponds to a cable connector arranged outside the housing. Additionally or optionally, the reader interface includes a loop antenna connector for connecting to an inductive loop to communicate with an active transponder. For example, an electric field detected by an active transponder can be sensed, and the reader interface further includes a wireless communication antenna for communicating with the active transponder. The loop antenna connector preferably corresponds to a cable connector arranged outside the housing. In other words, the decoder can be connected to an RFID reader arranged outside, or the decoder can be directly connected to the inductive loop to utilize the active RFID transponder. Typically, the corresponding cable is arranged outside the housing for easy access. Typically, such a cable connector is waterproof or moisture-proof.

[0025] In another embodiment, the protective cover is configured to cover the upper part of the housing front side and is pivotably hinged about a pivot axis substantially parallel to the housing top side and the housing front side, the pivot axis preferably being located in the plane of the housing top side. Additionally or alternatively, the protective cover has a curved shape, in particular spanning an angle of about 90°. By using a protective cover hinged about an axis in the plane of the housing top side and having a curved shape, a larger size of the cable connection interface can be used. This allows for simple access and convenient operation.

[0026] In another embodiment, the user interface includes a waterproof display, preferably a monochrome LCD display and / or a display with a multicolor screen backlight. Additionally or optionally, the user interface is arranged on the top side of the housing. The use of a waterproof display enables a series of different information to be displayed to the user independently of weather conditions. The monochrome LCD display can provide good readability even in sunlight conditions. The multicolor screen backlight enables additional information to be provided to the user, such as the current position of the corresponding decoder. For example, the decoder can be indicated to be located at a specific segment timing position by assigning a color to the segment timing position. This enables effective communication between operators. The arrangement of the user interface on the top side of the housing provides convenient accessibility and good readability.

[0027] In an embodiment, the housing and / or the cover includes a locking mechanism having a magnet for magnetically holding the cover in a closed state. Such a magnet-based locking mechanism enables simple access while securely locking the cover in a closed state. Connecting a cable to the cable connection interface becomes easy and efficient.

[0028] In an embodiment, the lower portion of the protective cover is configured to cover a portion of the housing below the cable connection interface in the closed state. Additionally or alternatively, the housing includes a brush extension for reaching the lower portion of the protective cover in the closed state to allow the network cable and / or computer interface cable to pass through the brush extension to connect to the cable connection interface, while maintaining a barrier to environmental influences, in particular to splashing water. The protective cover reaches a position lower than the cable connection interface, thereby providing a physical barrier to water. In the closed state, water will drip along the protective cover and will not be able to reach the cable connection interface. Additionally or alternatively, the brush extension ensures that no water can flow along the cable and enter the cable connection interface due to capillary effect. The robustness against rain, splashing water and / or dust is further improved.

[0029] In an embodiment, the housing includes a top connection portion in the area of ​​the top side of the housing and a matching bottom connection portion in the area of ​​the top side of the housing, and a matching bottom connection portion in the area of ​​the bottom side of the housing, for realizing the stackability of multiple decoders. Preferably, the housing includes a groove in the area of ​​the bottom side of the housing, which matches the space for opening and closing the protective cover of another decoder stacked below. Stacking the decoders provides an effective storage capacity for multiple decoders. If in this stacked state, the cable connection interface can still be accessed by opening the protective cover, effective charging, reprogramming, software updates, etc. can be achieved. For this reason, the protective cover of one decoder is opened into the groove of the decoder stacked above. Therefore, all protective covers of multiple decoders in the decoder stack can be opened.

[0030] In an embodiment, the housing includes two battery compartments for accommodating two batteries and a battery fixing mechanism configured to fix the battery in the first battery compartment while allowing the battery in the second battery compartment to be replaced. The battery fixing mechanism includes two additional protective covers for closing the two battery compartments and a closing element for fixing the additional protective covers in a closed state.

[0031] The closing element is configured to close both of the other covers at the same time in the first position to fix the two batteries in the two battery boxes, and in the second and third positions, selectively close one of the other covers while opening the other of the other covers to fix one battery while allowing the other battery to be replaced. The closing element is preferably pivotable between the first, second and third positions. The use of two batteries enables one battery to be replaced during operation. When one battery is replaced, the other battery can power the decoder. In addition, redundancy can also be provided. By using the covers to close the two battery boxes, the robustness against environmental influences is improved. The batteries are protected from water, dust, etc. The closing element ensures that only one cover can be opened at each time point, thereby ensuring continuous power supply to the decoder. If only one battery box can be opened at a time, it is ensured that there is always a battery in the battery box to power the decoder. This function can preferably be implemented in the form of a pivotable closing element. This enables efficient implementation and good usability.

[0032] In an embodiment, the two further covers are transparent to allow a user to visually assess the presence and / or charging status indication of the batteries in the two battery compartments. Additionally or optionally, the two further covers are arranged on the same side of the decoder as the cover. The transparent further cover allows assessing whether one or two batteries are inserted into the battery compartment. For example, a battery providing a charging status indication can be used. This can be read by the user through the transparent further cover, enabling an effective assessment of the battery charging status. If the further cover is arranged on the same side of the decoder as the cover, in addition to being able to replace or access the batteries at the same time, the decoders can also be stored in a decoder stack and the cables can be connected to the cable connection interface. This arrangement thus improves usability and efficiency when handling multiple decoders.

[0033] In an embodiment, the decoder includes a ventilation unit for ventilating the interior of the housing with outside air. The ventilation intensity is controlled based on the readings of the temperature sensor and the humidity sensor included in the decoder. By using the readings of both the temperature sensor and the humidity sensor, the weather adaptability control of the ventilation unit can be performed. For example, if the decoder is used in a skiing competition and is stored in a relatively warm storage space before being placed outdoors in the snow, it may be meaningful to ventilate the interior to remove moisture from the condensed water from the interior of the housing despite the low temperature. This improves the robustness to changing weather conditions and increases the life of the decoder.

[0034] In an embodiment, the decoder includes a ventilation outlet connecting the interior of the housing with the exterior and a ventilation inlet connecting the exterior with the interior. The ventilation outlet and the ventilation inlet are arranged below the protective cover. The protective cover preferably includes a barrier protrusion for forming an airflow barrier between the ventilation outlet and the ventilation inlet below the protective cover in a closed state. In particular, the barrier protrusion may include an opening for a power cable plug so that the plug closes the barrier protrusion when inserted. The outlet and the inlet are protected from environmental influences by being placed under the protective cover. The robustness of the decoder is improved. The barrier protrusion ensures that there is no or only very little direct airflow between the inlet and the outlet under the protective cover, otherwise the ventilation efficiency will be reduced. When the power cable is inserted, the opening for the power plug is closed. In other words, when the power plug is plugged in, the airflow between the inlet and the outlet is particularly reduced, and ventilation is necessary because the battery may be charged, etc.

[0035] In an embodiment, the decoder comprises an RFID chip for carrying information about the decoder, in particular identification information for identifying the decoder. Preferably, the RFID chip is programmable via the processing unit. Using an additional RFID chip can provide the advantage of contactless detection of the decoder. For example, if a plurality of decoders are stored in the storage space, an inventory can be easily performed. By programming the RFID chip, additional information can thereby be provided. For example, the charge state of the battery or the software version in stock can be evaluated without the decoder being powered on. Energy can be saved and availability can be improved.

[0036] In an embodiment, the decoder comprises a buffer element for placing the decoder on the underlying surface, the buffer element having a protrusion on a side of the housing opposite to a side of the protective cover, so that placing the decoder in a position with the cable connection interface facing upwards will cause the decoder to tip over. The buffer element improves the robustness of the decoder. The protrusion has the effect that it is not possible to place the decoder in a position where the cable connection interface may be exposed to rain. The possibility of error can be reduced and it can be ensured that incorrect use or abnormal handling does not necessarily lead to defects.

[0037] In an embodiment, the processing unit is configured to synchronize the operation of multiple RFID reader circuits connected in a daisy chain via the reader interface. The term synchronization therefore refers to avoiding interference between directly adjacent passive RFID readers. Adjacent readers may interfere with each other, which may result in a lower detection rate of passing sports timing transponders. By synchronizing the operation, in particular the time synchronization, this situation can be avoided and the detection rate can be improved. Daisy chain refers specifically to a series connection.

[0038] In an embodiment, the decoder includes an active RFID reader processing circuit for determining the elapsed time of the active sports timing transponder. Additionally or alternatively, the decoder includes a heating unit for heating the battery in the battery compartment. The heating unit preferably includes an aluminum plate. Additionally or alternatively, the decoder includes a communication unit for communicating via a mobile communication network, the communication unit having a first SIM module for accommodating a first physical or virtual SIM card and a second SIM module for accommodating a second physical or virtual SIM card. Preferably, the first SIM module is accessible to the user and the second SIM module is inaccessible to the user. The use of an active RFID reader processing circuit makes it possible to use a decoder connected to an induction loop for communicating with an active RFID sports timing transponder and / or for detecting an active RFID sports timing transponder. The heating unit allows optimizing the battery life and the operation of the decoder under cold conditions (particularly charging the battery in a cold environment). Although the connection is also guaranteed when the user does not insert a SIM card or inserts a SIM card that is not connected, the use of two different SIM modules enables the user to use his own mobile communication network. Therefore, reliability is improved.

[0039] In this article, the term "circuit" may refer to hardware implemented by means of different single electronic components such as resistors, transistors, capacitors, inductors and dials. However, the term "circuit" may also refer to a function implemented in a microcontroller. Therefore, this embodiment can be based on software and / or hardware. All combinations are possible, for example, a part of the circuit is implemented in hardware, and another part is implemented in the form of software running on a microcontroller. In particular, the computing unit can be implemented in the form of a microcontroller, which also performs other functions at least in part. External forces or environmental influences can be mechanical shocks, such as mechanical shocks from a runner stepping on a channel element or a boat passing through a channel element. External forces or environmental influences can also be weather conditions such as rain, cold / hot temperatures, dust, etc.

[0040] In this article, sports timing transponder refers in particular to a passive RFID tag, which has no integrated energy source, but is activated by an RFID reader to send the identification of the passive RFID tag. However, in some embodiments, the sports timing transponder may also correspond to an active RFID tag. Sports events refer in particular to running events such as marathons. However, sports events may also be bicycle races, car races, ski races, horse races, swimming races, etc. The identification of the sports timing transponder may in particular be an alphanumeric number of the RFID tag. The alphanumeric identifier is programmed into the transponder at the time of manufacture. The determination of the elapsed time may include multiple activations and readings of the identification of the sports timing transponder. Then, for example, the time of the strongest reading may be considered to represent the elapsed time (based on the elapsed time detection of the received signal strength). As used herein, the term decoder refers to a piece of hardware used in sports events to determine the elapsed time of a passing sports timing transponder. The decoder does not necessarily decode any signal. In particular, the decoder does not necessarily include an RFID reader. The term central protection area does not mean that the corresponding area must be arranged at the geometric center. Offset is possible. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] exist Figure 1 In the figure, a plurality of participants participating in a sports event are schematically shown. Participant 10 can be a runner in a running event such as a marathon in particular. Participant 10 is identified by a bib 12 corresponding to the participant ID. For example, bib 12 can be attached to the participant's shirt, the handlebars of a bicycle, or the chassis of a racing car. In the example shown, a passive RFID sports timing transponder 14 has been attached to bib 12. The sports timing transponder 14 is used to perform the measurement of the elapsed time and to determine the identification via RFID when participant 10 crosses the starting line or the finish line or passes through a segment timing measurement point.

[0068] In order to perform the measurement of the elapsed time, the present invention proposes to utilize a game timing system 16, which comprises a decoder 18 and a ground cable channel 20 comprising a plurality of channel elements 22. In at least some of the channel elements 22, antennas are arranged for reading the passing sports timing transponders 14 in order to determine their elapsed time. In this context, the channel elements 22 in which the antennas and the computing antennas are arranged are referred to as detection components.

[0069] Figures 2 to 7 Different views of an embodiment of a decoder 18 according to an aspect of the present invention are shown. Figures 2 to 7 In all other drawings, corresponding reference numerals represent the same components. However, for the sake of clarity, not all reference numerals are inserted in all drawings. For the same reason, sometimes it is avoided to insert the same reference numeral multiple times in a single figure to represent several similar components.

[0070] Figures 2 to 7 The decoder 18 in FIG. 1 includes a reader interface 24 , a cable connection interface 26 , a user interface 28 , a housing 30 , and a processing unit disposed within the housing 30 .

[0071] According to the invention, a user interface 28 is arranged on the outside of the housing 30. In the example shown, the user interface 28 comprises a display 32, via which configuration feedback is provided to the user, in addition to a plurality of buttons 34 allowing the user to interact with the decoder 18 and, for example, providing configuration information. In particular, the user can obtain information about the status and current readings of the decoder 18 via the user interface 28. For example, the elapsed time of a sports timing transponder can be displayed or the ID of a passing sports timing transponder can also be displayed.

[0072] In the exemplary embodiment shown, when the decoder 18 is placed on the ground, the user interface 28 is arranged on the top side of the housing 30 facing upward. The user interface 28 can be rainproof or splashproof and / or resist further environmental influences such as direct sunlight or mechanical stress, thereby allowing operation in outdoor applications. Preferably, the display 32 can be implemented in the form of a monochrome LCD display, which can be read out during the day when illuminated by the sun. The display 32 can be additionally equipped with a multicolor screen backlight, and can therefore be displayed with different color lighting. Through this additional information, the user configuration parameters can be effectively notified, such as information related to the timing position currently assigned to the decoder 18.

[0073] The cable connection interface 26 includes in particular a network cable connector and / or a computer interface cable. In the example shown, the cable connection interface 26 includes three different network cable connectors 36 (network sockets), a conventional USB connector 38, and a USB-C connector 40. The USB connector 38 and the USB-C connector 40 are configured to connect a computer interface cable corresponding to a USB cable. The cable connection interface 26 may include additional interfaces, such as a power interface 41 for connecting a power cable and other devices.

[0074] In order to protect the connector from environmental influences, especially splashing water, the cable connection interface 26 is arranged under the protective cover 42. Figure 2 , Figure 4 , Figure 6 and Figure 7 The closed state of the protective cover 42 is shown, and Figure 3 and Figure 5 The protective cover 42 is shown in an open state, in which the cable connection interface 26 is accessible.

[0075] The protective cover 42 is preferably arranged to cover the upper part of the front side of the housing 30. Therefore, the front side corresponds to the side of the housing 30 that is substantially at a 90° angle to the top side of the housing and that faces the direction of the user when the user reads the display 32. Figure 3 and Figure 5As shown, the cover 42 can be opened to allow access to the cable connection interface 26. When the cover 42 is open, cables can be connected and disconnected.

[0076] In the illustrated embodiment, the cover 42 is pivotally hinged about a pivot axis 44 that is substantially parallel to the top side of the housing and the front side of the housing. As shown, the pivot axis 44 is located in the plane of the top side of the housing 30.

[0077] from Figure 2 and Figure 3 As can be seen in the figure, the cover 42 can in particular have a curved shape, which in the embodiment shown spans an angle of 90°. In order to lock the cover 42 in place, the illustrated embodiment of the decoder 18 comprises a housing 30 having a locking mechanism 46. The locking mechanism 46 comprises at least one magnet 48 for magnetically holding the cover 42 in the closed state. In the embodiment shown, two magnets 48 are positioned in a portion of the housing 30 that is covered by the cover 42 in the closed state. The magnets 48 interact with corresponding counterparts 50, in particular magnets or metal plates integrated in the cover 42. When the cover 42 is closed, it is held in place by the interaction of the magnets 48 with the counterpart 50. It should be understood that the positions of the magnets and the counterparts can also be exchanged accordingly.

[0078] In the illustrated embodiment, the protective cover 42 includes a lower portion 52 which, in the closed state, covers a portion of the housing 30 below the cable connection interface 26. This prevents rain or splashing water that strikes the decoder 18 from reaching the cable connection interface 26 and the connector disposed therein despite the capillary effect.

[0079] Furthermore, in the embodiment shown, the housing 30 comprises a brush extension 54 which, in the closed state, reaches the lower portion 52 of the protective cover 42. Thus, the brush extension 54 corresponds in particular to a brush which allows the cable to pass through the bristles, but prevents splashing water and water flowing along the cable from entering the cable connection interface 26. The bristles of the brush extension 54 further increase the resilience against environmental influences by providing an additional barrier.

[0080] In the illustrated embodiment, the reader interface 24 is disposed on the rear side of the housing 30 and includes a passive RFID connector 58 and a loop antenna connector 60 .

[0081] The passive RFID connector 58 is connected to one or more RFID reader circuits, which also have an antenna connected to them. The passive RFID connector 58 is configured to receive detection of a passive RFID sports timing transponder. In particular, the passive RFID connector 58 can be configured to connect to a ground cable channel that includes multiple detection components, each detection component having an antenna and circuit for detecting an RFID tag.

[0082] The loop antenna connector 60 is configured to be connected to an inductive loop for communicating with an active sports timing transponder. In particular, an electric field can be induced, which can then be detected by the active RFID sports timing transponder. The active RFID sports timing transponder can calculate the elapsed time by itself and transmit their elapsed time, for example, via a wireless connection and the wireless communication antenna 62 of the decoder 18.

[0083] In the illustrated embodiment, the decoder 18 includes a top connection 64 disposed in the top side region of the housing 30 and a matching bottom connection 66 disposed in the bottom side region of the housing 30. The top connection 64 and the bottom connection 66 work together to provide stackability of multiple decoders 18. Thus, the top connection 64 can provide two grooves on the top side of the housing 30, into which two or four protrusions on the bottom side of the housing 30 forming the bottom connection 66 can extend. Thus, stackability provides better storability for multiple decoders 18. Multiple decoders 18 can be stacked on top of each other.

[0084] In the embodiment shown, the housing 30 comprises a recess 68 in the bottom area of ​​the housing 30, which recess 68 provides space for opening and closing the protective cover 42 of another decoder stacked below. Thus, if a plurality of decoders are stacked on top of each other, their protective covers 42 can still be opened, because in the open state the protective covers 42 can extend into the recess 68 of the decoder 18 stacked above. This results in accessibility of the cable connection interfaces 26 of all decoders in the decoder stack.

[0085] Furthermore, the decoder 18 in the illustrated embodiment includes two battery boxes 70 configured to accommodate two batteries. A battery fixing mechanism 76 allows the batteries to be placed and fixed in the battery box. To this end, the battery fixing mechanism 76 includes two additional protective covers 72 and a closing element 78. The battery box can be closed by the two additional protective covers 72. Figure 6 As shown, the further cover 72 can be pivoted, for example, about two pivot axes 74 in order to allow access to the battery. A closing element 78 enables the two covers 72 to be fixed in the closed position.

[0086] Thus, the closing element 78 is configured to simultaneously close the other two covers 72 in the first position, and to selectively close only one of the other covers 72 while opening the other of the other covers 72 in the second and third positions. In the embodiment shown, the closing element 78 is implemented in the form of a pivotable and irregularly shaped element that mechanically fixes one or both of the two other covers 72. Thus, the pivot axis of the closing element 78 is perpendicular to the Figure 5 and Figure 6 . Preferably, the closing element 78 can be held in one of the first position, the second position and the third position by a spring or another locking mechanism. The closing mechanism 78 makes it possible to replace one battery while keeping the other battery fixed in the battery compartment 70. Therefore, it is possible to maintain power supply when replacing one of the batteries. The other two covers 72 are preferably transparent to allow the user to visually assess the presence and / or charge status indication of the batteries in the battery compartment 70. The charge status of the battery can also be assessed when the decoder itself is not working and / or is in low power mode. In combination with the stackability as described above, the transparency makes it possible to also assess the presence and / or charge status of the battery when multiple decoders are stacked on each other.

[0087] The decoder 18 may further include a cushioning element 80. In the illustrated embodiment, the cushioning element 80 includes two rubber elements surrounding the housing 30 on the left and right sides. Thus, the cushioning element 80 increases the ability of the decoder 18 to resist mechanical stress during storage or during operation at a sporting event. Figure 7 As shown in the side view in , the buffer element 80 has a protrusion 82 on the rear side of the housing 30 opposite to one side of the protective cover 42. In the illustrated embodiment, the protrusion 82 is formed so that the decoder 18 falls over when placed on the protrusion 82. The protrusion 82 corresponds to the rounded portion of the buffer element 80. In other words, the shape of the buffer element 80 is irregular, so that when the protrusion 82 is facing downward, the decoder cannot stand safely on the ground. This makes it impossible to place the decoder 18 in a position where the protective cover 42 and the cable connection interface 26 arranged below are facing upward. Therefore, even if the user attempts to place the decoder 18 so that the cable connection interface 26 is facing upward in the direction of heavy rain, this is impossible to do.

[0088] Figure 8 The decoder 18 and its various components are schematically shown. The dashed lines represent optional components. The decoder 18 includes a reader interface 24, a cable connection interface 26, a user interface 28, a processing unit 84, a housing 30, and a protective cover 42.

[0089] Optionally, the decoder 18 comprises a ventilation unit 86 for ventilating the interior of the housing 30 with external air. In the embodiment shown, the ventilation outlet 45 and the ventilation inlet 47 are arranged below the protective cover 42, so as to protect them from environmental influences, in particular splashing water and rain. Air can enter and leave the space below the protective cover 42 in the closed state through corresponding openings, such as the opening below the lower part 53 of the protective cover 42.

[0090] As further shown, the cover 42 may include a barrier protrusion 43 that forms an airflow barrier between the ventilation outlet 45 and the ventilation inlet 47 below the cover in the closed state and blocks air from flowing directly between the inlet and the outlet. In the example shown, the barrier protrusion 43 corresponds to a lower protrusion 49 arranged in the space below the cover 42 in the closed state. However, other mechanical implementations are possible in this regard.

[0091] In particular, the barrier protrusion 43 may include an opening for a power cable plug. When the power cable is plugged in, the opening is closed and the airflow between the inlet and outlet is blocked when charging the battery or performing other power-consuming operations requiring ventilation.

[0092] Therefore, the ventilation unit 86 can be controlled based on the readings of the temperature sensor 88 and the humidity sensor 90 arranged in the housing 30. Therefore, the ventilation intensity of the ventilation unit 86 is adjusted to prevent water condensation inside the housing, which may cause damage to the electronic components included in the housing 30. The combination of the temperature sensor 88 and the humidity sensor 90 has an advantage that water condensation in the housing can also be prevented in the case of cold outside.

[0093] Further optionally, the decoder 18 may include an RFID chip 92 for carrying information about the decoder 18. In particular, the RFID chip 92 is programmable via the processing unit 84. This enables information about the decoder 18 to be obtained by reading out the RFID chip 92 with a corresponding reader even if the processing unit 84 is not working or is not switched on (e.g., for energy saving). For example, if a plurality of decoders 18 are stored, inventory control is facilitated. By programming the RFID chip 92 with the processing unit 84, further information can be written on the RFID chip 92. For example, the recharge status of the battery can be provided as further information to be read out. Because the readout can be performed when the decoder 18 and the processing unit 84 are not powered at all or are running at very low power consumption, energy can be saved.

[0094] In addition, the decoder 18 can include an active RFID reader processing circuit 94 for determining the elapsed time of an active sports timing transponder. The active RFID reader processing circuit 94 can specifically interact with an inductive loop connected to the loop antenna connector. The active RFID sports timing transponder can wirelessly transmit information to the wireless communication antenna of the decoder.

[0095] Furthermore, the decoder 18 may comprise a heating unit 96 for heating at least one battery in one of the battery compartments. The heating unit may in particular comprise an aluminum plate which is arranged close to (in particular above) the battery in the battery compartment. By heating or warming the battery, it is also possible to operate the decoder 18 in cold environments (in particular to be able to charge the battery in cold environments) and to increase the operating time and life of the battery.

[0096] Furthermore, the decoder 18 may comprise a communication unit 98 for communicating via a mobile communication network. In particular, this is advantageous in the case where the communication unit 98 has a first SIM module for accommodating a first physical or virtual SIM card and a second SIM module for accommodating a second physical or virtual SIM card. By using two SIM cards, it is possible to have one SIM card accessible by the user, while the other SIM card is arranged internally and cannot be accessed by the user. Thus, the user can insert his own SIM card and communicate via a wireless network of his choice, while the other SIM card is provided by a service provider and ensures that the service provider has access to the decoder 18 to provide software updates, etc., independently of the user's own SIM card and mobile network connection.

[0097] The processing unit 84 is configured to control different components. In addition, the processing unit 84 can process data received via the reader interface 24 and transmit the processed data to the Internet. The processing unit 84 can also control components, in particular detection components connected via the reader interface 24, for example by providing synchronization signals or configuration parameters. The processing unit 84 can be implemented in the form of a microcontroller or a system chip (SoC) running corresponding software.

[0098] Fig. 9 A schematic diagram of a match timing system 16 according to an aspect of the present invention is shown. The match timing system 16 includes a decoder 18 in addition to a ground cable channel 20, wherein the ground cable channel 20 has six channel elements 22, each of which includes an antenna and a computing unit to form a detection assembly 102. The cable channel 20 is connected to the decoder 18 via a cable 100, which connects the computing unit in the detection assembly 102 to a reader interface of the decoder 18.

[0099] The ground cable channel 20 comprises a plurality of detection assemblies 102, each of which comprises an antenna and a computing unit arranged in a channel element 22. Thus, the channel element 22 corresponds to a mechanical protection of the antenna and the computing unit connected to the antenna to protect the antenna and the computing unit from external forces, such as ships passing through the ground cable channel 20, weather conditions like snow or rain, or participants in a running event, etc. Thus, a plurality of detection assemblies 102 form a line. Thus, the number of detection assemblies 102 in a line or in a ground cable channel 20 is flexible. For example, six detection assemblies 102 can be connected.

[0100] Fig.10 and Fig.11 Different options for wiring multiple detection assemblies 102 of a floor cable channel 20 are shown. Each detection assembly 102 includes a channel element 22, a computing unit 104, and an antenna 106. Each channel element 22 is connected to a preceding channel element 108 and a following channel element 110. It should be understood that the following and previous descriptions are outlined from the perspective of a detection assembly 102 in the middle of the floor cable channel 20 shown, but the concepts apply to all different detection assemblies 102.

[0101] like Fig.10 As shown, computing unit 104 may be connected to a first adjacent computing unit 112 via a first cable 114 and to a second adjacent computing unit 116 via a second cable 118. Thus, first cable 114 extends into the front channel element 108 and second cable 118 extends into the rear channel element 110.

[0102] Fig.11 An optional configuration is shown. The computing unit 104 is connected to a first adjacent computing unit 112 located in a front channel element 120 via a first cable 114. Therefore, the front channel element 120 corresponds to the channel element before the front channel element 108. Similarly, the computing unit 104 is connected to a second adjacent computing unit 116 located in a rear channel element 122. In other words, every other computing unit 104 in the ground cable channel 20 is connected so that basically two communication chains are formed. The cables bypass the front channel element and the rear channel element respectively. By utilizing two communication chains, resilience to mechanical defects can be improved. For example, if one communication line is damaged, another communication line is still available, so that at least partial detection can still be performed. For greater clarity, Fig.11 The connections between each computing unit 104 and the antenna 106 in the channel element are not shown.

[0103] Fig.12The computing unit 104 of the detection component is schematically shown. The computing unit 104 includes a voltage detection circuit 124. Optionally, the computing unit 104 includes a data bus circuit 126, a terminal detection circuit 128, a position detection circuit 130, a reconfiguration circuit 132, a communication circuit 134, a defect detection circuit 136 and an RFID reader circuit 138. Therefore, different components (circuits) can be implemented partially or completely using software and / or hardware. One component can realize the functions of multiple circuits. In particular, the computing unit 104 can correspond to a microcontroller having multiple peripheral devices and other electronic components connected thereto. The computing unit can also be called a reader unit or an RFID reader.

[0104] The voltage detection circuit 124 is configured to detect whether power is provided to the computing unit 104 via the first cable or via the second cable. In particular, this makes it possible to determine which of the two cables the computing unit 104 is connected to a decoder that provides power supply and receives determined information from a passing sports timing transponder. Therefore, the voltage detection circuit 124 may include a metal oxide semiconductor field effect transistor that is capable of switching electrical power from one computing unit in the chain to the next computing unit. Alternatively, a bipolar junction transistor (BJT), a relay or other switch may be used. When the detection component is started, that is, when the initial power is connected, the voltage detection circuit 124 determines which side the power is provided from. Then, the through connection is initialized so that the power is directly connected to the corresponding adjacent computing unit. During operation, and in the case of power failure (new installation, reconnection, reconfiguration, etc.), the corresponding memory portion is deleted, and it is detected from which of the first cable and the second cable to re-supply power.

[0105] The data bus circuit 126 can provide data bus communication with further computing units of further detection components connected via the first cable and the second cable in the daisy chain. Therefore, data bus communication refers in particular to serial bus communication, which provides communication with or without a host device. In particular, the data bus circuit 126 can provide CAN bus communication. Optionally, another bus system can be used, in particular a differential bus system such as RS-485. Powernet can also be used. Different computing units connected to each other in the chain can communicate with a processing unit located in a decoder connected to a ground cable channel. Serial communication is established.

[0106] Terminal detection circuit 128 allows detection of whether computing unit 104 is connected to only one of the first adjacent computing unit and the second adjacent computing unit. For example, if no other computing unit is connected, a resistor can be switched to terminate the data bus. At initial startup, the default operation is preferably that each computing unit in the chain terminates the data bus communication. If power is connected to the first computing unit in the chain, then check whether the adjacent computing unit acts on one of the data pins of the bus communication. Only in this case, the data bus is directly connected to the corresponding adjacent computing unit. This can ensure that data bus communication can be established. In order to detect defects in data bus communication, a timeout function can be implemented. If a predetermined time has passed after data bus communication cannot be performed, the terminal detection circuit 128 terminates the data bus communication again, and only when it is determined that the corresponding adjacent computing unit acts on one of the data pins, communication is reestablished. This makes it possible to reconfigure during operation.

[0107] The position detection circuit 130 makes it possible to detect multiple computing units connected via a first cable and / or multiple computing units connected via a second cable. Therefore, the position detection circuit 130 can announce its presence on the data bus at startup. In a centralized communication scheme with a central host or master device, it can be assigned a number corresponding to its position in the chain from the master device. Optionally, it is also possible that when a startup message is received from a new computing unit in the chain, all other computing units already present in the chain provide a response message on the data bus, so that the position detection circuit can evaluate the multiple computing units that are already present and can assign themselves the next higher number corresponding to their position in the chain. Other possible schemes include only the other computing units with the current highest ID responding.

[0108] The reconfiguration circuit 132 enables detection of a change in the number of computing units connected via the first cable and / or a change in the number of computing units connected via the second cable. This again enables detection of a defect in one of the computing units in the chain during operation or reconfiguration of the floor cable channel during operation.

[0109] The communication circuit 134 may be particularly suitable for communicating with a decoder and a processing unit of the decoder, the decoder being connected via a first cable or via a second cable. Thus, the communication circuit 134 may provide a data bus communication, preferably a CAN bus communication. The communication circuit 134 may be configured to receive a synchronization signal from the decoder for synchronizing the operation of a circuit of a detection component or a computing unit in a computing unit chain, respectively. In addition, position information may be received from the decoder, the position information indicating the position of the computing unit in the computing unit chain from the perspective of the decoder. The position information may form the basis for an effective bus communication.

[0110] The defect detection circuit 136 is used to detect defects in the computing units. In particular, the defect detection circuit 136 can be implemented in the form of a separate integrated circuit. This makes it possible to connect two adjacent computing units to each other even if the central microcontroller of the computing unit 104 is defective. The connection thus comprises in particular a data communication and a power connection. The defect detection circuit 136 makes it possible to obtain additional safety against hardware failures. As soon as a defect is detected, the corresponding computing unit is skipped, so that at least partial functionality of the cable channel can be maintained.

[0111] The RFID reader circuit 138 may in particular correspond to a circuit required for detecting a passing RFID transponder. In particular, the calculation unit may therefore correspond to an RFID reader. The signal obtained via the antenna is evaluated to determine whether a passive RFID tag corresponding to a sports timing transponder has passed. If a passing passive RFID tag is detected, the corresponding passing time is determined. In particular, the received signal strength (RSS) may therefore still be evaluated. However, alternatively / additionally, a phase change of the signal may be evaluated.

[0112] exist Fig.13 In FIG. 1 , an embodiment of a floor cable channel 20 of the present invention is schematically shown. The floor cable channel 20 shown includes six detection components 102 interconnected to form a line. Fig.13 In (a), the floor cable channel 20 is in an operating position, wherein the different channel elements 22 are arranged one behind the other along their longitudinal axis. Fig.13 (b) schematically shows that the floor cable channel 20 can be brought into a transport position by rotational movement of adjacent channel elements 22 relative to each other in the direction of the arrows shown. Fig.13 (c) shown. Fig.13 (b) schematically shows one of the rotation axes 140. Fig.13 In the transport position shown in (c), the channel elements 22 of the floor cable channel 20 are arranged parallel to each other.

[0113] The match timing system of the present invention can be easily installed by bringing the floor cable duct 20 from the transport position into the operating position. For example, if a plurality of floor cable ducts 20 have to be installed at a sports event, installation is facilitated by enabling the different floor cable ducts 20 to be transported to their respective positions in the transport position and deployed by the rotational movement shown.

[0114] In order to provide this rotation function, different channel elements 22 of the floor cable channel 20 are connected to their adjacent channel elements by connecting elements 142. These connecting elements 142 can be similar to joints. For example, a single hook or a double hook representing a connecting element 142 can be snapped into a corresponding socket in an adjacent channel element 22.

[0115] exist Fig.14 , another embodiment of the match timing system 16 of the present invention is schematically shown. The match timing system 16 comprises a ground cable channel 20 connected to a decoder 18 and a further decoder 144. The two decoders 18, 144 are arranged on two different sides of the ground cable channel 20. On the one hand, this installation can provide redundancy if one of the two decoders 18, 144 fails. On the other hand, it can also be as Fig.11 Two separate chains of computational units are shown connected independently to separate decoders 18 , 144 .

[0116] exist Figures 15 to 17 , an embodiment of a detection assembly 102 is shown including a channel element 22, an antenna 106, and a computing unit 104. The channel element 22 includes a top portion 150 and a bottom portion 152, which can be connected to the top portion 150. Fig.15 The detection assembly 102 is shown with a top portion 150 covering a bottom portion 152 in which the antenna 106 and the computing unit 104 are disposed. Fig.16 The bottom 152 of the channel element 22 is shown without the antenna 106 , the computing unit 104 and the connecting cables. Fig.17 The bottom portion 152 is shown with the antenna 106, the computing unit 104 and the corresponding cables therein. The connection between the top portion 150 and the bottom portion 152 may be implemented in the form of a snap or snap-fit ​​mechanism.

[0117] The antenna 106 and the calculation unit 104 can be arranged on two printed circuit boards stacked together with a spacer layer in between. Thus, the spacer layer can be implemented in particular in the form of a polystyrene layer. The antenna 106 can be implemented in particular in the form of a patch antenna. By using the polystyrene layer between the calculation unit 104 and the antenna 106, suitable directional characteristics of the antenna 106 can be obtained in the desired direction (in particular upwards when the detection assembly is placed on the ground in order to detect sports timing transponders of participants of sports events).

[0118] Reference Figures 15 to 17, the channel element 22 comprises a first connection portion 154 for connecting the channel element 22 to a preceding channel element and a second connection portion 156 for connecting the channel element 22 to a succeeding channel element. As shown and also as explained above, the connection can thus be implemented, for example, in the form of one or more connection elements 142 designed to snap onto corresponding protrusions 158.

[0119] The channel element 22 comprises a central protection area 160 in which the antenna 106 is accommodated. Furthermore, the channel element 22 comprises a first protection area 162 for accommodating the first cable 114 and a second protection area 166 for accommodating the second cable 118. Thus, the first protection area 162 connects the central protection area 160 to the first connection part 154, i.e., the connection part to which the channel element is connected to the preceding channel element. Thus, a cable can be introduced from the central protection area 160 to the first connection part 154. The second protection area 166 connects the central protection area 160 to the second connection part 156. Furthermore, the channel element 22 comprises a bypass protection area 170, which connects the first connection part 154 to the second connection part 156. In this respect, the term "connected" means that the respective protection area is designed to house and protect the respective connection cable.

[0120] In the illustrated embodiment, the central protection region 160, the first protection region 162, and the second protection region 166 correspond to cavities formed between the top portion 150 and the bottom portion 152. In particular, the cavities are formed in the bottom portion 152 and are covered by a flat section of the top portion 150.

[0121] Thus, the channel element 22 of the invention makes it possible to connect the computing units in every other channel element to each other (for data and power transmission) in a line of a plurality of channel elements connected by their respective connecting parts. Thus, the second cable 118 of one detection assembly connects the computing unit of the detection assembly to the computing unit in the channel element following the next channel element. Thus, the second cable 118 is guided through the bypass protection area 170 of the next channel element.

[0122] Fig.18 Schematically shows a cross-sectional view of the channel element of the present invention. As shown in the figure, the top 150 is perpendicular to the longitudinal axis of the channel element ( Fig.18The top 150 is provided with a plurality of flexible projections 172 on each side of the top 150. The flexible projections 172 are designed to adapt to the unevenness of the underlying surface. Thus, the flexible projections 172 extend along the longitudinal axis of the channel element so that the top can provide direct contact of the channel element 22 with the underlying surface over the entire length of the channel element.

[0123] exist Fig.19 , an embodiment of a floor cable channel 20 including four detection assemblies and four channel elements is shown. The following description and explanation will be understood from the perspective of the second channel element 22 or detection assembly 102 on the left, but can be applied to other channels in the line and longer / shorter floor cable channels.

[0124] The channel element 22 is connected to the preceding channel element 108 at its first connection 154 and to the following channel element 110 at its second connection 156. In the illustrated embodiment, the preceding first connection 154a of the preceding channel element 108 is connected to the first connection 154 of the channel element 22. The following second connection 156b is connected to the second connection 156 of the channel element 22. The first cable 114 extends from the first protection area 162 to the preceding bypass protection area 170a of the preceding channel element 108. The second cable 118 in the second protection area 166 is guided to the following bypass protection area 170b in the following channel element 110. Thus, as described above, the computing units in every other detection assembly are connected. In the illustrated example, the computing unit in the preceding channel element 108 is connected to the computing unit in the following channel element 110 by a cable passing through the bypass protection area 170 of the channel element 22.

[0125] like Fig.19 As shown, the cable outlets of the first protection area 162 and the bypass protection area 170 at the first connection portion 154 (optionally) are arranged at a different distance from each other than the cable outlets of the second protection area 166 and the bypass protection area 170 at the second connection portion 156. Therefore, the first connection portion 154 can only be connected to the preceding first connection portion 154a of the preceding channel element 108. This structure makes it possible to avoid cable crossing, which further increases stability.

[0126] like Fig. 20 and Fig.21 As shown, it is possible that either both computing unit chains are connected on one side of the cable channel ( Fig. 20 on the left side of the floor cable channel 20), or different chains are connected on both sides of the floor cable channel 20 ( Fig.21 ).

[0127] exist Fig. 22, the bottom 152 of the channel element 22 is schematically shown. In this example, the bypass protection area 170 is designed to include a relay part 174 in addition to the terminal part 176. Therefore, the relay part 174 is designed to connect the first connection part 154 to the second connection part 156, that is, to guide the cable through the entire channel element 22 between two corresponding cable outlets. On the other hand, the terminal part 176 is designed to store the end of the cable in the bypass protection area 170. The cable in the bypass protection area can be placed optionally in the terminal part 176 or the relay part 174. Therefore, in the case where the channel element 22 represents the last channel element in the ground cable channel, cable overlap can be prevented. In the bypass protection area 170, the cable from the previous channel element can be placed and protected from environmental influences. In order to prevent the cable from overlapping outside the channel element 22, if no other channel elements need to be connected, the cable can be stored (by the user) in the terminal part 176.

[0128] exist Fig.23 , Fig.24 and Fig.25 , a preferred embodiment of the connection between the cables 114, 118 (first cable or second cable, respectively) and the computing unit 104 is schematically shown. The computing unit 104 can be connected to the first cable 114 and / or the second cable 118 via a first connector part 178 and a second connector part 180, which are designed to be screwed together by screws 182 to establish an electrical connection (and a stable mechanical connection). In the embodiment shown, the electrical connection has four conductors. However, a different number of conductors can also be used. Fig.23 In particular, the first connector component 178 is shown. Fig.24 The second connector component 180 is particularly shown, and Fig.25 Specifically shown are two connector parts 178 , 180 screwed together by screws 182 .

[0129] Compared to previous methods that rely on plug and socket connections, the use of screws 182 to connect the first connector part 178 and the second connector part 180 enables a stable connection that provides mechanical stability in a relatively small construction space. In addition, efficient manufacturing is possible. It should be understood that the connection principle including the first connector part 178 and the second connector part 180 can also be used independently of the design of the channel element 22 as shown in other figures and as described in this article and / or in other application fields.

[0130] As shown, the antenna 106 and the computing unit 104 can be integrated in an assembly and, for example, can be arranged on a common printed circuit board. For mechanical protection, the assembly can be placed in a housing or the like. The connection of the computing unit 104 (and the antenna 106) to the first cable 114 and / or the second cable 118 can be established via a first connector component 178 on one side of the computing unit 104. As shown, the first connector component 178 can include a printed circuit board 184. In particular, the printed circuit board 184 can accommodate the computing unit 104. In the illustrated embodiment, the first connector component 178 includes four spring pins 188 for establishing an electrical connection when the second connector component 180 is screwed to the first connector component 178. The spring pins 188 are spring-loaded pins for establishing an electrical connection and providing a durable and resilient electrical connection.

[0131] In the illustrated embodiment, the second connector component 180 also includes a printed circuit board 186 having holes 192 for screws 182. As shown, when the second connector component 180 is not connected to the first connector component, the screws are (optionally) secured by clips 194 to prevent loss of the screws 182. The first connector component 178 may include a threaded connector 190 designed to receive the screws 182.

[0132] The two connector parts 178, 180 are screwed together by a screw 182. In the embodiment shown, the screw is configured to be manually operated without a screwdriver by means of a hinged clamp 196 attached to the screw 182.

[0133] Between the two connector parts 178, 180, a seal (not shown) may be arranged to protect the actual conductors from moisture. At least one of the two connector parts 178, 180 may be designed to keep the seal in place, also when not connected.

[0134] In this document, circuits are described with particular reference to the functionality of different circuits. The functionality can be achieved by software and / or hardware. For example, the corresponding functionality can be implemented partially or completely in software running on a microcontroller. Thus, each computing unit may include a microcontroller that either implements the corresponding functionality alone or communicates and interacts with other passive or active electrical components such as resistors, capacitors and inductors to implement it.

[0135] The foregoing discussion discloses and describes only exemplary embodiments of the present disclosure.
