Definitions
- the present invention relates to a portable system for acquiring and detecting a so-called arbitration acoustic signal, signaling a stop and / or resumption of the playing time of a sports event, intended to be worn by a referee of the sporting event.
- It also relates to a digital audio communication terminal, for audio communication between several arbiters, integrating such a portable acquisition and detection system.
- It also relates to a fixed system for controlling the playing time of the sports event, intended to be in radio communication with such a portable acquisition and detection system, as well as a game time control facility. including such a fixed control system in radio communication with such a portable acquisition and detection system.
- the referee signals a stoppage of time by a whistle; the whistle being generally duly homologated and referenced by the federation in charge of these sports events or by any other sworn organization for these sporting events. It is also conceivable that the same referee signals the resumption of playing time by the same whistle, which then triggers the start or restart of the stopwatch.
- the actual game phases are particularly fast and choppy, with many game stops in the course of the game, so that the oversights or stopping delays of the stopwatch are regular and lead disputes always difficult to settle for the referees.
- a fixed system comprising a radioreceiver placed on the brand table, in radio link with the portable radio-controlled transmitters, followed by a mixer which mixes the raw analog measurement signals, then a high-pass filter and a pass filter filter; low, then an electronic control circuit that delivers a switching signal to the stopwatch.

- this analog radio link distorts and colors the transmitted analog signals and modifies their signature, thus affecting the reliability of their detection.
- the components used for transmission, transmission and analysis of analog signals have their own characteristics (bandwidth, distortion, different filtering effects, etc.), which modify the analog signal permanently. It is said that the system colors the analog signal, in other words modifies the spectral response of this analog signal.
- Each transformation of the analog signal generated by these components necessarily generates background noise because each component creates it.
- the major disadvantage of an analog system is the irreversible degradation of the analog signal, the system being unable to distinguish the useful signal from the background noise.
- the radio link being analog, there is no way to catch a call if it is scrambled, or even to detect the failure of the system so that, on the one hand, whistles may not be detected by the fixed system following electromagnetic disturbances induced by external electronic devices and that, on the other hand, these same external electronic devices can disturb the analog signal transmitted to the point of erroneously triggering the stopping of playing time.
- the state of the art can also be illustrated by the teaching of the international application WO 00/73858 which discloses a portable system (signaling device) for acquiring and detecting an acoustic signal called arbitration (sensor signal) , including the whistle type, signaling a stop and / or resumption of playing time of a sporting event.

- the digital arbitration signal S23 forming the whistle detection information S4, can thus be transmitted for a few seconds to ensure its transport. If necessary, the digital arbitration signal S23 can be acknowledged by a return, of the AR acknowledgment signal type, generated by the fixed system 3 after the countdown of the playing time has been stopped.
- the transmission means 24, and more generally the transmission / reception means 86 are designed to integrate in one of the time slots of each cycle 5 a cyclic redundancy signal which makes it possible to verify the integrity transmitted cycles, so that:
- a first possibility of restarting the countdown of playing time is to provide an audio detection of a voice command of the referee, such as a keyword of the type "Start” or "Chrono".
- the portable system 2 is designed so that:
- the digital processing means 23 process and analyze the digital acoustic measurement signals in order to detect, among the acoustic signals measured by the acoustic measurement means 20, a specific vocal command emitted by the arbiter to signal the resumption of the measurement time. game, these digital processing means 23 delivering a digital recovery signal S29 play time in response to the detection of said voice command; and
- This first possibility is particularly well suited to the case where the portable system 2 is integrated in a communication terminal 8.
- a second possibility of restarting the countdown of playing time is to provide for manual detection of an action by the referee, such as for example pressing a button or switch.
- the portable system 2 further comprises manual actuation means 29 for the recovery of time, in particular of the type switch or keypad key, intended to be manually operated by the referee to signal the resumption of the time of play, as shown in Figure 1.
- the digital processing means 23 are connected to the actuating means 29, said digital processing means 23 delivering a digital restart signal S29 of the play time in response to the actuation of the manual actuating means 29 by the 'arbitrator.
- the transmission means 24 are designed to emit said digital signal for playing time.
- the reception means 30 are designed to receive the or each digital recovery signal S29;
- control means 31 are designed to generate a restart control signal S39 in response to the reception of a digital recovery signal S29 by the reception means 30;
- the game time counting means 32 are shaped to put or restart the play time count in response to the issuance of the restart control signal S39.
- this action of restarting the countdown of playing time uses the same digital radio communication channel as when detecting the whistle S4 and stopping the countdown of playing time.
- each cycle 5 of the communication channel may have a time slot reserved for the transmission of this digital signal for resumption of the game time S29.
