The invention discloses a wireless transmission pulse-taking method and system which are suitable for a pulse-taking instrument. The method comprises the steps that firstly, a connection request instruction sent by an intelligent device is received, and wireless connection with the intelligent device is established; secondly, when a collection starting instruction sent by the intelligent device is received, first feedback information is sent to the intelligent device, and collection operation begins to be executed; thirdly, pulse information of a user is collected, and the collected pulse information is sent to the intelligent device; fourthly, when a collection stopping instruction sent by the intelligent device is received, second feedback information is sent to the intelligent device, and collection operation is stopped; fifthly, the intelligent device saves and analyzes the pulse information, and a pulse graph is obtained. By means of the technical scheme, the method and the system have the advantages that the pulse-taking instrument is small in size and convenient to carry, the pulse-taking instrument is connected with the intelligent device in a wireless mode, operation is easy, and the pulse graph of the user to be detected is displayed through a display screen of the intelligent device visually and is beneficial for follow-up analysis.
