Description

Screen projection method, device and system, electronic equipment and storage medium Technical Field The present invention relates to the field of screen projection, and in particular, to a screen projection method, apparatus and system, electronic device and storage medium. Background With the continuous development of computer technology and electronic technology, intelligent electronic devices are increasingly widely used. When using intelligent electronic devices, people often need to perform a screen-throwing operation between the electronic devices, that is, content displayed on a screen of one electronic device is displayed on a screen of another electronic device, for example, content displayed on a mobile phone screen is displayed on a vehicle-mounted terminal. In the prior art, when a content displayed on a mobile phone screen is projected on a vehicle-mounted terminal, a user is required to search Bluetooth names of target vehicles one by one from a Bluetooth list of the mobile phone, and projection is performed after the target vehicles are selected. The Bluetooth list of the mobile phone is used for displaying Bluetooth names of all nearby Bluetooth-enabled vehicles. If the Bluetooth names of the same vehicles exist in the Bluetooth list of the mobile phone, the user of the mobile phone does not know how to select, and the wrong selection also causes the leakage of the privacy of the user. For mobile phone users, the screen projection method is complex in operation, has the possibility of privacy leakage and is poor in user experience. Disclosure of Invention The application aims to provide a screen projection method, which has the advantages that a screen projection end triggers screen projection operation, specifically receives a broadcast signal sent by the screen projection end, performs the screen projection operation according to the screen projection information carried in the broadcast signal, does not need a user to search the screen projection end at the screen projection end, is convenient to operate, reduces the error rate of screen projection connection, and improves user experience. The application further aims to provide a screen projection method which has the advantages that whether the screen projection request prompt is displayed is judged according to the popup window zone bit in the screen projection information, and the screen projection method is simple and convenient and high in judgment efficiency. The application further aims to provide a screen projection method, which has the advantages that whether a screen projection request prompt is displayed or not is judged by combining a popup window zone bit and a screen projection zone bit in screen projection information, and particularly, the screen projection request prompt is not displayed under the condition that a screen projection end is projecting, so that the situation that a user breaks the screen projection between the screen projection end and other electronic equipment after confirming the screen projection through the electronic equipment is avoided, and the screen projection experience of the user is improved. Another object of the present application is to provide a screen projection method, which has the advantages that if it is determined that a screen projection request prompt is displayed and there is no screen projection record of a screen projection on a target electronic device, the screen projection request prompt is displayed, and the screen projection is performed only after a user agrees to the screen projection request prompt, so that the privacy and the data security of the user in the electronic device are ensured. Another object of the present application is to provide a screen projection method, which has the advantages that if it is determined that a screen projection request prompt is displayed and a screen projection record of a screen projection on a target electronic device exists, a screen projection operation is directly performed without displaying the screen projection request prompt, that is, without a user confirming that a screen is projected on the target electronic device again, so that efficiency of projecting a screen to the same screen-projected end, that is, the target electronic device is improved. Another object of the present application is to provide a screen projection method, which has the advantage that if at least two screen projection request prompts are judged to be displayed according to the received broadcast signals sent by the plurality of screen projection terminals, the screen projection request prompts are displayed through interaction with the user, specifically, the screen projection request prompts are displayed in response to the sliding operation of the user, so that the man-machine interaction experience is improved. Another object of the present application is to provide a screen projection method, which is capable of timely responding to a user-trigge
