A pulse output control method, an apparatus, an electronic device, and a computer storage medium. The method is applied to an electrical stimulation apparatus, said method comprising: determining a target massage mode; obtaining pulse information and an electrode conduction sequence corresponding to the target massage mode; wherein the electrode conduction sequence comprises at least one electrode conduction subsequence, each electrode conduction subsequence comprises at least two conduction time segments and an identifier for an electrode being provided conduction within each conduction time segment, and the pulse information includes pulse amplitude change information; controlling n electrodes in outputting massage pulses of changing pulse amplitude on the basis of the pulse information and the electrode conduction sequence corresponding to the target massage mode. By utilizing the present method, a user can select a massage mode and output a continuously changing massage pulse as needed, reducing a relatively large percussive feeling on the body from a massage pulse, and improving massage comfort for the user.
A: Disclosed is a massage chair control system, comprising: a plurality of pressure measurement units which are arranged in a plurality of massage areas of a massage chair; a heart rate measurement unit which is arranged on the surface of a hand massage area of the massage chair; a facial image collection unit which is arranged in a backrest area of the massage chair; a control unit in which different massage modes are preset; and a cloud service platform which is used for: calculating, according to pressure data, a massage intensity needing to be output in each massage area; identifying the age range and the gender of a user according to facial feature data; calculating a psychological stress value of the user according to heart rate data; selecting different massage modes for the user on the basis of the massage intensity, the age range and the gender; and adjusting, on the basis of a change in the psychological stress value, the control unit to output different massage modes and massage durations during a massage process. An intelligent massage mode output of a massage chair is realized.
B: A massage mode starting method for a wearable massaging apparatus, comprising: reading the state information of a user of a wearable massaging apparatus within a preset period of time (101); and when the state information is a rest state within the preset period of time, controlling the wearable massaging apparatus to start a first massage mode (102), wherein the massage intensity of the first massage mode is less than preset intensity. Further disclosed are a wearable massaging apparatus and a terminal device. The wearable massaging apparatus can obtain the state information of the user of the wearable massaging apparatus within the preset period of time. If it is detected, according to the state information, that the user does not do sports but is in the rest state within the preset period of time, the wearable massaging apparatus can be controlled to start the first massage mode, thereby realizing the automatic starting of the massage mode of the wearable massaging apparatus, without the user manually starting the wearable massaging apparatus, and improving the intelligence of the wearable massaging apparatus.
C: A pulse current output control method, comprising: acquiring, in real time, a first driving voltage output to a pulse output circuit, the first driving voltage being used for driving the pulse output circuit to output a first pulse current; and when the first driving voltage does not meet a predetermined voltage condition, indicating that the massage device is not closely attached to a human body part, adjusting the first driving voltage until a second driving voltage satisfying the predetermined voltage condition is obtained, and controlling the pulse output circuit to be driven by the second driving voltage to output a second pulse current, the second pulse current being smaller than the first pulse current.
D: A method and apparatus for controlling a targeting massage device, the method comprising: acquiring exercise information (S101); and controlling the operation of the targeting massage device on the basis of the exercise information (S102). The method of the present invention can automatically acquire exercise information when a user is exercising and thus can control the targeting massage device to perform, on the basis of the exercise information acquired when the user is exercising, a targeting movement. The invention thereby automatically provides the user with the most comfortable, adequate, and effective massage corresponding to the exercise information so as to provide optimized massaging to achieve better, faster physical recovery after exercising while removing the need for the user to manually select a massage mode, thereby requiring minimal user input.
