[0032] It should be noted that the indoor monitoring host 1 is installed in a cabinet in a communication room. Indoor refers to the internal environment of the communication room. Outdoor refers to the external environment of the communication room, and the specific location can be determined according to the actual needs of the application scenario. In this embodiment, the outdoor monitoring host 2 and the first antenna module 3 are both installed outdoors, wherein the outdoor monitoring host 2 can be installed by hanging on a wall or holding a pole, or other fixed installation methods.

[0033] The first room wireless sensing module 5 is used to send a wireless excitation signal to the first antenna module 3. The first antenna module 3 is used to transmit a first feedback information when receiving the wireless excitation signal sent by the first room wireless sensing module 5.

In addition, the present application saves transmission network resources for wireless signal monitoring by constructing a star-shaped network architecture.

[0036] In a preferred embodiment, each first room-based wireless sensing module 5 is correspondingly connected to a first antenna module 3 .

[0037] In a preferred embodiment, the first room-based wireless sensing module 5 is connected to the first antenna module 3 via a passive antenna feed system.

[0038] It should be noted that the passive antenna feed system refers to a system in which the antenna radiates electromagnetic waves into the surrounding space. The passive antenna feed system consists of feeder lines, power dividers, couplers, and antennas, which transmit the cluster signal from the base station to the corresponding radiation area to achieve perfect coverage.

[0039] Specifically, the passive antenna feed system can transmit wireless signals from the sending device to the receiving device to achieve communication, and can also convert electrical signals into electromagnetic waves and radiate them through the antenna to enhance signal strength.

[0040] like Figure 1-2 As shown, the dotted line between the first room wireless sensing module 5 and the first antenna module 3 in the figure represents a passive antenna feed system.

[0041] In a preferred embodiment, the first antenna module 3 includes a first antenna unit and a first wireless sensing tag;

[0042] The first wireless sensing tag is arranged on the first antenna unit and is wirelessly connected to the first room wireless sensing module 5 .

[0043] It should be noted that the first wireless sensing tag is deployed on the first antenna unit. The first room-based wireless sensing module 5 includes a radio frequency unit, which is used to send a first wireless excitation signal to the first wireless sensing tag. The first wireless excitation signal is used to activate the first wireless sensing tag. The first feedback information includes the wireless signal under the coverage of the first antenna unit. When the first wireless sensing tag is activated, the first wireless sensing tag is used to sense the wireless signal under the coverage of the first antenna unit, and send the wireless signal to the first room-based wireless sensing module 5 of the outdoor monitoring host. Among them, the wireless signal can be used to feedback the quality of wireless communication under the coverage of the first antenna unit.

[0044] In practical applications, by setting up a first wireless sensing tag and setting up a communication connection between the first wireless sensing tag and the first indoor wireless sensing module 5 of the outdoor monitoring host 2, the quality of wireless signals within the coverage of the first antenna unit can be monitored.

[0048] It should be noted that, in the present embodiment, the indoor monitoring host 1 and the outdoor monitoring host 2 perform data exchange by using a transmission protocol including but not limited to MQTT, SNMP, TR069 and HTTPS.

[0049] In a preferred embodiment, the indoor monitoring host 1 is provided with a second room-divided wireless sensing module 6 and at least one second antenna module 7; the second antenna module 7 is provided indoors;

[0050] The second room wireless sensing module 6 is connected to the second antenna module 7 .

[0051] It should be noted that the second room-based wireless sensing module 6 is connected to the second wireless module via a wireless antenna feed system.

[0052] The second room wireless sensing module 6 is used to send a wireless excitation signal to the second antenna module 7. The second antenna module 7 is used to transmit a second feedback information when receiving the wireless excitation signal sent by the second room wireless sensing module 6. The second feedback information is used to characterize the operation of the second antenna module 7. The indoor monitoring host 1 is used to receive the second feedback information and realize the monitoring of the indoor wireless signal, so as to provide data support for the signal radiation quality identification and wireless signal quality analysis of the indoor antenna, and provide technical support for intelligent operation.

[0053] In two preferred embodiments, the second antenna module 7 includes a second antenna unit and a second wireless sensing tag;

[0054] The second wireless sensing tag is arranged on the second antenna unit.

[0055] It should be noted that the second wireless sensing tag is deployed on the second antenna unit. The second room-based wireless sensing module 6 includes a radio frequency unit, which is used to send a second wireless excitation signal to the second wireless sensing tag. The second wireless excitation signal is used to activate the second wireless sensing tag. The second feedback information includes the wireless signal under the coverage of the second antenna unit. When the second wireless sensing tag is activated, the second wireless sensing tag is used to sense the wireless signal under the coverage of the second antenna unit, and send the wireless signal to the second room-based wireless sensing module 6 of the indoor monitoring host. Among them, the wireless signal can be used to feedback the quality of wireless communication under the coverage of the second antenna unit.

[0056] In practical applications, by setting a second wireless sensing tag and setting the second wireless sensing tag to communicate with the second room wireless sensing module 5 of the indoor monitoring host 1, the quality of wireless signals under the coverage of the second antenna unit can be monitored.

[0057] In an example, both the first antenna unit and the second antenna unit may adopt existing common antennas.

[0058] In two preferred embodiments, the network interface 4 is also used to connect to a sensing device; the sensing device is used to collect target sensing information.

[0059] It should be noted that, in this embodiment, the indoor monitoring host 1 is provided with a plurality of network interfaces 4, wherein the network interface 4 can also be used as an expansion interface to meet the expansion needs of the user. The sensing device can be a device for collecting data determined by the user according to the monitoring needs, and the target sensing information can be the sensing information required by the user collected by the sensing device. In one example, the sensing device can be a sensor device, such as a temperature sensor, a humidity sensor, or a position sensor, and the target sensing information can be humidity, temperature, or position.

[0060] Therefore, this embodiment enriches the functions of the indoor monitoring host 1 by setting multiple network interfaces 4 for meeting the user's expansion needs in the indoor monitoring host 1, realizes more different types of data aggregation and transmission, and provides users with richer monitoring functions. It broadens the application scenarios.

[0061] In a preferred embodiment, the protection grade of the box of the outdoor monitoring host 2 is IP65.

[0062] It should be noted that the IP in IP65 is the abbreviation of Ingress Protection. The IP level refers to the protection level of the electrical equipment housing against the intrusion of foreign objects. The number "6" represents the dustproof level, which means that the product has a high dustproof ability and can completely block the entry of dust. The parts and circuit boards inside the product will be effectively protected and will not be corroded by dust. The number "5" represents the waterproof level, which means that the product has moderate waterproof ability and can resist the entry of low-pressure jet water. Even in the case of strong water spray, the inside of the product will remain dry.

[0063] This embodiment adopts an IP65 protective outer box as the housing of the outdoor monitoring host 2, so that the outdoor monitoring host 2 can better adapt to the monitoring needs of outdoor environments such as subway depots.
