Detailed Description

The technical scheme of the invention is specifically explained below with reference to the accompanying drawings.

The invention provides a novel sports competition timing system.A starting gun with a wireless transceiving function simultaneously starts timing devices in hands of a plurality of timekeepers in a wireless mode, and immediately sends out timing results through setting after the timekeepers press a stop timing button for displaying competition results in real time.

The timing system has an intelligent error correction function, and under the timing state, the timing time at that time can be stored every time the start/stop key is pressed; when the timing device is used alone, if an operation of starting in advance occurs when timing is started, the start/stop button may be pressed again, and the timing time may be calculated with this time as a start point.

The timing system has a single multipoint timing function, namely after the timer is started, a timing time is recorded by pressing a start/stop key once, so that a timer can time a plurality of players at the same time.

The starting gun is internally provided with a starting gun circuit, the starting gun circuit comprises a main control MCU circuit and a first wireless transceiving module connected with the main control MCU circuit, the main control MCU circuit adopts ATMEGA16, and the first wireless transceiving module adopts NRF24L 01. The timing device comprises a timing circuit and a second wireless transceiver module connected with the timing circuit, the timing circuit adopts ATMEGA16, and the second wireless transceiver module adopts NRF24L 01.

The following is a specific implementation of the present invention.

The invention is divided into a starting gun and an end timer, and a set of system generally comprises a starting gun and one or more end timers. The end point timer can also be set to independently complete the timing work. Wherein the circuitry of the pistol is shown in figure 1.

As can be seen from FIG. 1, the pistol circuit is mainly composed of an MCU ATMEGA16 and a wireless transceiver module NRF24L 01. The ATMEGA16 is a central control unit MCU, the NRF24L01 is responsible for transmitting and receiving wireless signals, is connected with the MCU in an interrupt mode and occupies an external interrupt request signal INT 2. The button K1 in the figure is electrically connected to the gun trigger of the pistol and occupies the INT0 interrupt request line of MCU ATMEGA 16. When the starter gun is fired by the starter, an interrupt request signal is sent to the ATMEGA16 central control unit via this button. The ATMEGA16 central control unit receives the interrupt request signal and responds to the interrupt request signal, and sends a starting timing command to all the end timers of the timing system of the group through the NRF24L01 wireless module. Because all the end-point timing devices receive the instructions in parallel and simultaneously, the linear distance between the starting gun and the end-point timer is less than 100m under the general condition, the transmission speed of a wireless signal is about 3X105 km, the transmission time is less than 0.3us, and the time required by the processing of the central processing unit is added, the time delay is still within ten thousandth of a second and is far less than the one hundredth of a second of the conventional general condition, so that the synchronization and the accuracy of the timing start are fully ensured.

After the referee fires the starting pistol at the starting point, a key K1 in fig. 1 is pressed down, an interrupt request is sent to the MCU, the MCU responds to the interrupt request, and sends an instruction through the SPI bus and the wireless transceiver module NRF24L01, and all terminal timers in the system are started to start timing. The electrical schematic of the terminal timer is shown in fig. 2.

The terminal timer mainly comprises a CPU MCU ATMEGA16, a 2.42 inch 128X64 OLED display, an NFR24L01 wireless transceiver module and 4 keys. Whereas the U2 OLED display uses the SPI bus, the definition of the relevant pins is as follows:

GND Power ground

VCC power supply is

SCL clock

SDA data line

RES reset line

DC data/command select line

CS chip selection line

Set up 4 multi-functional buttons on the terminal timer for the user sets up or timing operation:

START/STOP button. In the state of a single meter (non-networking state), the mode is set to time counting, the first time of pressing is the starting time counting, and a piece of time counting time is recorded every time of pressing. Until the secondary MODE/CLEAR (MODE/CLEAR) key is pressed continuously.

CONFIRM button CONFIRM. After exiting the timing state (by pressing the 2-time mode/clear button in succession), press

The operator can enter a MODE design state, such as networking timing or single-meter timing, system time setting, an error correction MODE of operation, a transmission MODE of a timing result and the like, by pressing a MODE/CLEAR MODE/zero clearing key for a short time. Pressing this key completes the setting, returning to the previous state.

MODE/CLEAR MODE/CLEAR key. The key is a multifunctional key, and the mode setting state is entered by pressing twice for a short time; in the mode setting state, for example, whether the timing device is set to independently finish timing or jointly finish timing with a starting gun, system time setting, whether data is transmitted through a wireless transmission module immediately after timing data is determined, and the like. And switching one mode every time of short pressing, and circularly displaying.

NEXT/ROTATE NEXT key, in set state, using NEXT key to make value or mode selection, for example, selecting 0-9 digits when setting hour/minute/second. Pressing the key for a long time indicates that the setting of the current number or state is completed, and the next data/state setting item is shifted.

When the terminal timer is set to be in the networking timing state (used in combination with the starting gun), the wireless transmission module starts timing immediately after receiving a starting timing command transmitted by the starting gun. In this state, every time the start/stop button is pressed, a current timing time is stored. Therefore, even if the referee mistakenly presses the key, the phenomenon of exposure does not occur. Meanwhile, the function can also be used for one timekeeper to time a plurality of players at the same time (for example, in the case that a sports teacher organizes a result test on a sports class, and one coach carries a plurality of players).

When the terminal timer is set to be in an independent timing state, the start timing is indicated when the start/stop button is pressed for the first time, and a timing time is recorded every time the start/stop button is pressed for the next time until the timing is finished by continuously pressing the 2-time mode/clear button.

whether timing data is transmitted, when data is transmitted or which data is transmitted can be set through wireless transmission in a mode or a zero clearing key, and the automation degree is improved.

The above are preferred embodiments of the present invention, and all changes made according to the technical scheme of the present invention that produce functional effects do not exceed the scope of the technical scheme of the present invention belong to the protection scope of the present invention.
