The invention relates to a frequency band locking method and device, a computer device and a storage medium. The method comprises the following steps of displaying a frequency band scanning list; determining a target frequency band selected from the frequency band scanning list; generating the frequency locking data corresponding to the selected target frequency band; analyzing the frequency locking data to obtain a frequency band identifier of the target frequency band; generating a control parameter according to a preset standard parameter and a frequency band parameter corresponding to thefrequency band identifier; and triggering the locking of the target frequency band through a frequency locking request generated based on the control parameter. By adopting the method, the frequency band locking efficiency can be improved.
