when all preparation is completed, the examination begins.

First, the host computer 10 is in the test mode interface, presses the "start" key, and waits for the command from the command issuing device 11 after identification.

Then, the starting apparatus 11 sends a preparation signal to the host computer 10 while making a voice, telling the host computer 10 that the start is ready, and the host computer 10 can start detecting the start instruction. If the start signal sent by the infrared single-point detector 14 is received in this period, the race is judged to be racing, the system is recovered to the initial race mode interface, and the start key needs to be pressed again to enter the waiting state. The 'prepare, peng' start running instruction sound is sent out, the timing of the main machine 10 is started. Meanwhile, waiting for the start signal sent by the infrared single-point detector 14, if the time for receiving the start signal is shorter than the reaction time of a normal person, the system judges that the race is robbed, the system recovers to the initial race mode interface, and the system needs to press the start key again to enter the waiting state. Otherwise, the system starts to time and the competition continues. The data display 13 displays personnel information, timing status, and the like.

Then, the competitor holds the hook ladder to run to the training tower, climbs from the first floor to the fourth floor, enters the window of the fourth floor, and treads the pedal detector 12 with both feet. The pedal detector 12 transmits a finish signal, the main machine 10 stops timing immediately after receiving the finish signal, and the data display screen 13 displays the final result of the competition.

After recording the result of the current competition, the host computer 10 reenters the examination mode interface, presses the start key, and waits for the command from the command issuing device 11. After the second examination is finished, the examination scores are recorded, then the scores of the two times are compared, and the selected score is the final score of the examinee and is displayed on the data display screen 13.

The system re-enters the test mode interface and waits for the command of the command issuing device 11 after the identity of another test person is identified. The system enters a second testing mode as the first testing person. And sequencing and displaying the final scores of the second examiners.

After each examiner obtains the final score, the system sends the final score to the data display screen 13 and also sends the final score to the remote server 21 at the cloud end of the network, so that the system is convenient for a background or other terminals to inquire in time.
