Description

一种协同屏蔽方法、屏蔽***、存储介质及电子装置A cooperative shielding method, shielding system, storage medium and electronic device 技术领域technical field
本发明实施例涉及通信领域，具体而言，涉及一种协同屏蔽方法、数据屏蔽方法、主机屏蔽设备、从机屏蔽设备、屏蔽***、存储介质及电子装置。Embodiments of the present invention relate to the field of communications, and in particular, to a collaborative shielding method, a data shielding method, a host shielding device, a slave shielding device, a shielding system, a storage medium, and an electronic device.
背景技术Background technique
目前在执行信号屏蔽时，一般是在目标区域设置屏蔽设备，通过屏蔽设备对基站或信号发射设备发送的信号、数据进行干扰，以此来实现信号屏蔽。At present, when performing signal shielding, shielding equipment is generally set in the target area, and the signal and data sent by the base station or signal transmitting equipment are interfered with by the shielding equipment, so as to realize signal shielding.
但是在一些通信***中，会对屏蔽器的屏蔽时隙进行限制；例如，在TDD(Time Division Duplexing，时分双工)***中，不允许屏蔽器在上行时隙发射屏蔽信号，否则会干扰整个基站运行，因而要求屏蔽器在执行屏蔽工作时，在屏蔽时段的大部分时间内发干扰信号，在极短的时间内不发干扰信号，并这在极短的时间里，屏蔽器还要能够接收基站下行信号，并分析出基站的上下行时隙，以实现屏蔽器只干扰基站的下行时隙的功能。However, in some communication systems, the masking time slot of the masker will be restricted; for example, in the TDD (Time Division Duplexing) system, the masker is not allowed to transmit the masking signal in the uplink time slot, otherwise it will interfere with the whole The base station is running, so the jammer is required to send out interference signals during most of the shielding period and no jamming signals in a very short period of time when performing the shielding work. Receive the downlink signal of the base station, and analyze the uplink and downlink time slots of the base station, so as to realize the function that the masker only interferes with the downlink time slot of the base station.
在大多数场合，单台屏蔽器只能屏蔽一定范围的区域，要屏蔽超过这个范围的区域，就需要使用多台屏蔽器。而多台屏蔽器同时工作的时候，在任一屏蔽器发射干扰信号的时刻，其余的屏蔽器均无法接收到基站发射的下行信号，从而无法分析出基站的上下行时隙，进而使得其余屏蔽器无法执行正常的屏蔽功能，影响屏蔽效果。In most cases, a single shield can only shield a certain range of areas, to shield areas beyond this range, you need to use multiple shields. When multiple jammers work at the same time, when any jammer transmits an interference signal, the other jammers cannot receive the downlink signal transmitted by the base station, so that the uplink and downlink time slots of the base station cannot be analyzed, and the remaining jammers cannot The normal shielding function cannot be performed, affecting the shielding effect.
而在相关技术中并没有能够有效解决上述问题的技术方案。However, there is no technical solution that can effectively solve the above problems in the related art.
