The invention discloses a heart rate test method. The heart rate test method includes the following steps that a received light intensity value and an equipment identification code sent by heart rate detection equipment are received; the received light intensity value and the equipment identification code are sent to a server side, so that the server side judges the received light intensity value; when the received light intensity value is larger than a preset light intensity value, the server side obtains a calibration value relevant to the equipment identification code according to the equipment identification code, a reference value is obtained according to the received light intensity value and the calibration value, and when the fact that the reference value is smaller than the preset light intensity value is judged out, a to-air test command is returned; and the to-air test command is received and sent to the heart rate detection equipment, so that the heart rate detection equipment sends out a to-air test statement according to the to-air test command. The invention further provides a user terminal, the detection equipment and a test system. Better accuracy and good user experience are achieved during to-air test judgment.
