[0002] The Ping command can be used to check the stability of the antenna RF port. In existing devices that implement the antenna Ping function, each antenna RF port corresponds to a modem chip. When performing the antenna Ping function, the signal transmitted by the base station is processed by the modem in the device and reaches the antenna RF port. The antenna RF port then feeds the signal back to the base station to detect the stability of the antenna RF port. Setting up multiple modem chips that correspond to the antenna RF ports one by one will bring the following disadvantages: (1) Multiple modem chips need to occupy a large amount of space inside the antenna, affecting the layout design of other components, resulting in a waste of costs and resources; (2) Since each modem chip has a certain power consumption when working, it is easy to increase the overall power consumption of the antenna.

[0023] The technical solutions of the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention.

[0024] The present invention discloses a device for realizing the antenna Ping function, which can realize the AISG3.0 multi-channel Ping function, and can effectively reduce the number of OOK (On-Off Keying, binary on-off keying) modems used, reduce the space occupied by the device inside the antenna, and reduce the overall power consumption of the antenna, thereby avoiding waste of costs and resources.

[0025] like Figure 1 As shown, a device for realizing the antenna Ping function disclosed by the present invention includes a host module and a slave module that are communicatively connected to each other, wherein the host module includes a main controller and multiple groups of AISG (Antenna Interface Standards Group) interfaces, the AISG interface is connected to the main controller, and the multiple groups of AISG interfaces are connected to at least one base station through an AISG cable. During implementation, the base station sends a Ping command to the main controller through the AISG cable. After receiving the Ping command, the main controller generates a Ping message and sends it to the slave controller. The slave controller sends the Ping message to the base station through a multiplexer, an OOK modem and an antenna RF port. The base station determines whether there is a fault in the link between the base station and the host module based on the Ping message.

[0026] The slave module includes a slave controller, a first OOK modem, at least one second OOK modem, at least one multiplexer, and multiple antenna RF ports, wherein the slave controller is connected to the master controller via the first OOK modem, each second OOK modem is respectively connected to the slave controller, and each second OOK modem is respectively connected to a multiplexer, and each multiplexer is respectively connected to multiple antenna RF ports. During implementation, the master controller sends a Ping message to the first OOK modem, the first OOK modem processes the Ping message and sends it to the slave controller, the slave controller further sends the Ping message to the second OOK modem, the second OOK modem processes the Ping message and sends it to the corresponding antenna RF port via the multiplexer, the antenna RF port feeds back a signal to the base station via the bias device inside the antenna, and then determines whether there is a stability problem with the antenna RF port.

[0027] In this embodiment, the multiplexer is preferably a fully solid-state multiplexer, which can realize the multiplexing of OOK modems, that is, multiplexing is realized with one modem, such as realizing 8-way, 16-way or 256-way multiplexing. Compared with the prior art, by setting up a multiplexer, one OOK modem can be connected to multiple antenna RF ports, and there is no need to set up an OOK modem separately for each antenna RF port, which effectively reduces the use of OOK modems and reduces the overall cost and volume of the antenna.

[0028] like Figure 1 As shown, the host module and the slave module communicate through the OOK message link, and the slave module can communicate with the host module through the OOK message link and realize its own firmware upgrade. Specifically, the OOK message link includes a first SMA interface, a second SMA interface, and a coaxial cable connecting the first SMA interface and the second SMA interface, and the coaxial cable can be used to transmit OOK signals and DC signals, wherein the first SMA interface is provided in the host module, and the first SMA interface is connected to the main controller, and the second SMA interface is provided in the slave module, and the second SMA interface is connected to the slave controller through the second OOK modem.

[0029] The host module and the slave module communicate via coaxial cable and SMA connector, which can provide very good signal shielding effect, is beneficial to the antenna PIM (passive intermodulation) index, and can avoid the problem of degradation of antenna standing wave ratio and intermodulation performance.

[0030] like Figure 1 As shown, taking the slave module including 1 first OOK modem, 2 second OOK modems, 2 multiplexers and 32 antenna RF ports as an example, the present invention is described in detail.

[0031] The first SMA interface is connected to the second SMA interface through a coaxial cable. In the host module, the first SMA interface is connected to the main controller. In the slave module, the second SMA interface is connected to the slave controller through the first OOK modem. Both second OOK modems are connected to the slave controller, and each second OOK modem is connected to a multiplexer. Each multiplexer is connected to 16 antenna RF ports. When performing antenna Ping, the base station sends a Ping command to the main controller through the AISG interface. After receiving the Ping command, the main controller generates a Ping message and sends it to the second OOK modem of the slave module. The second OOK modem processes the Ping message and sends it to the slave controller. The slave controller processes the received Ping message and transmits it to the corresponding second OOK modem. The second OOK modem modulates the signal and sends it to the corresponding multiplexer. The multiplexer sends the Ping message to the corresponding antenna RF port among the 16 antenna RF ports connected to it. The antenna RF port feeds back the signal to the base station through the bias device inside the antenna, thereby determining whether each RF path between the base station and the antenna is connected correctly, stably and reliably.

[0032] In this embodiment, the host module and the slave module both include a power supply module for providing power, an EMC suppression module for EMC suppression, and a lightning protection module for preventing lightning strikes.
