PROBLEM TO BE SOLVED: To provide a gunshot training system capable of accurately determining a degree of injury of a user.SOLUTION: A gunshot training system comprises an irradiation unit, an optical receiver and a processing unit. The optical receiver comprises a detector, a time counter, a decryption processing part and a wireless transmittance circuit. The detector generates an electrical signal when it receives a laser beam irradiated from the irradiation unit. A decryption processing part extracts data from the electrical signal and adds time information received from the time counter to the extracted data. The wireless transmittance circuit converts the data added with the time information into a wireless signal and transmits it. The processing unit comprises the wireless receiving circuit and a signal processing part. The signal processing part judges that data added with the same time information in the data added with the time information is data generated by irradiating the same laser beam.SELECTED DRAWING: Figure 1 |
