In a first aspect, an embodiment of the present invention provides a method for detecting loss of a transparent transmission port of a multi-system access platform, which is applicable to a port detection system, where the port detection system includes an input detection device and an output detection device, where the input detection device and the output detection device are both used to detect detection signal power of a transparent transmission port of the multi-system access platform, and may be executed by a processor or a remote control device, and the processor is used as an execution main body to describe below, where the detection method includes:

It should be noted that, in the embodiment of the present invention, the detection device for executing the method for detecting the loss of the transparent transmission port of the multi-system access platform includes an input detection device and an output detection device, and an application scenario of the detection device is to detect loss states of two transparent transmission ports in a multi-system access Platform (POI); in practical application, the transparent transmission ports of the multi-system access platform are connected with the radio frequency cable, wherein one transparent transmission port is an input port for transmitting a detection signal to the multi-system access platform, and the other transparent transmission port is an output port for the detection signal; the specific installation position of the loss detection device in the application scene is that the input detection device is correspondingly connected with the input transparent transmission port, and the output detection device is correspondingly connected with the output transparent transmission port and used for detecting the original signal power and the actual signal power of the detection signals transmitted through the two transparent transmission ports, so that the loss states of the two transparent transmission ports of the multi-system access platform are detected. The multi-system access platform (Point of Interface, abbreviated as POI) refers to a specific device located between a multi-system base station information source and an indoor distribution system antenna feeder, and is equivalent to a combiner with higher performance index, and has the functions of combining the multi-system base station information sources and outputting the combined information to the indoor distribution system antenna feeder device, and simultaneously outputting a signal from the antenna feeder device to each system information source in a shunting way in the reverse direction. Wherein, two output ports of a multisystem access Platform (POI) are transparent transmission ports, and the transparent transmission frequency band is (820 and 960 MHz).
When the processor responds to a detection starting operation instruction, a detection signal is sent to the leaky cable, the remote control device controls the detection signal generating device to output the detection signal to the transparent transmission port to be detected, and when the processor responds to the detection starting operation instruction, the detection signal generator in the input detection device is controlled to generate the detection signal and transmit the detection signal to the transparent transmission input port correspondingly connected to the input detection device, so that the detection signal enters the transparent transmission input port and is output from the transparent transmission output port of the multi-system access platform correspondingly connected to the output detection device. The processor acquires the initial signal power of the detection signal detected by the input detection device and acquires the actual signal power of the detection signal detected by the output detection device; and calculating a power difference value between the actual signal power and the initial signal power, judging whether the power difference value meets a preset insertion loss requirement, and judging that the transparent transmission port of the multi-system access platform has a fault when the processor judges that the power difference value does not meet the insertion loss requirement. And judging the states of the two transparent transmission ports according to the loss power values of the detection signals transmitted by the transparent transmission ports detected by the input detection equipment and the output detection equipment, so that the working states of the transparent transmission ports of the multi-system access platform can be monitored in real time. The processor actively sends the detection signal to the transparent transmission input port of the multi-system access platform when responding to the detection operation starting instruction, so that the transparent transmission port can be detected in real time no matter the multi-system access platform equipment is in a working state or a preliminary debugging state, and the radio frequency signal transmitted by the transparent transmission port when the multi-system access platform is in a communication state is not required to be detected. Because the input detection equipment and the output detection equipment are fixedly arranged on the corresponding detection positions of the multi-system access platforms, the loss condition of the transparent transmission ports of the multi-system access platforms is monitored remotely in real time, and the transparent transmission ports of the multi-system access platforms are detected without interrupting communication and carrying heavy equipment.
