Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
It should be noted that although functional block partitions are illustrated in block diagrams and logical sequences are illustrated in flowcharts, in some cases, steps shown or described may be performed in a different block partition or sequence in flowcharts.
The invention provides a signal processing method, which comprises the steps of firstly obtaining a radio frequency signal, and decoding the radio frequency signal to obtain a radio frequency parameter. And then, the radio frequency parameters are sent to a cloud server, so that the cloud server can manage the equipment according to the radio frequency parameters. The cloud server can sense the radio frequency parameters in the system, so that the equipment in the wireless intercom system is managed, each piece of equipment in the system is guaranteed to be in a normal state, and the equipment management capacity and the emergency command capacity of the wireless intercom system are improved.
The signal processing method and the wireless intercom system described in the embodiments of the present invention are for more clearly illustrating the technical solutions of the embodiments of the present invention, and do not constitute a limitation to the technical solutions provided in the embodiments of the present invention, and it is known to those skilled in the art that the technical solutions provided in the embodiments of the present invention are also applicable to similar technical problems with the evolution of the technical field of mobile communication and the emergence of new application scenarios.
As shown in fig. 1, an embodiment of the present invention provides a signal processing method. It is understood that the signal processing method includes, but is not limited to, step S100, step S200 and step S300.
Step S100, acquiring a radio frequency signal.
It is understood that during wireless intercom, information needs to be transmitted through electric waves, and radio frequency signals are modulated and have electric waves with a certain transmission frequency. Radio frequency carrier signals are generated in the wireless interphone, rated radio frequency power is generated through buffer amplification, excitation amplification and power amplification, harmonic components are inhibited through an antenna low-pass filter, and finally the radio frequency carrier signals are transmitted through an antenna. Meanwhile, the wireless interphone also receives radio frequency signals through the antenna. The signal received from the antenna is amplified in radio frequency through the transceiving conversion circuit and the band-pass filter, then the filter filters out the useless stray signal and amplifies and discriminates the useless stray signal to generate an audio signal, and the audio signal enters the volume control circuit and the power amplifier amplifying circuit through circuits such as amplification, the band-pass filter, de-emphasis and the like to drive the loudspeaker to obtain the information required by people.
And step S200, obtaining radio frequency parameters according to the radio frequency signals.
It will be appreciated that upon receiving the radio frequency signal, the radio frequency parameters need to be derived from the radio frequency signal. The radio frequency parameters can be used for judging parameters such as signal strength, power and the like of radio frequency signals received by the current antenna, so that the current equipment condition is judged.
Specifically, data such as signal reception strength, signal frequency, standing-wave ratio, and downlink power of the uplink radio frequency signal and the downlink radio frequency signal received by the antenna need to be detected, and the radio frequency signal needs to be decoded to obtain related device information in the system. The data in the radio frequency signals enable the server to sense the wireless intercom system, and therefore corresponding management is carried out.
Step S300, the radio frequency parameters are sent to a cloud server, so that the cloud server can manage the equipment according to the radio frequency parameters.
It can be understood that the cloud server can realize the perception of the wireless intercom system by means of the received radio frequency parameters, so that the signal coverage condition of the antenna is evaluated, the equipment in the system can be better managed, each equipment in the system is ensured to be in a normal state, and serious consequences caused by the fault of the wireless intercom system in case of emergency are avoided.
It should be noted that the radio frequency parameters are periodically updated in the cloud server, that is, the radio frequency parameters need to be periodically sent to the cloud server, and the data behind the cloud server is updated. The data are updated regularly, so that the equipment can be maintained better, and the emergency management capability of the system is improved.
As shown in fig. 2, fig. 2 is a specific flowchart further included before step S200 in fig. 1. It is understood that step S400 is included but not limited to before step S200.
Step S400, determining that the radio frequency signal meets a preset condition.
It can be understood that, after the radio frequency signal is obtained, it needs to be detected whether the radio frequency signal satisfies a predetermined condition. If the current equipment meets the requirement, the current equipment is normal; if not, the current equipment is possible to have faults and needs to be adjusted.
Specifically, it is determined that the radio frequency signal meets a preset condition, and it is required to determine whether the signal power and the standing-wave ratio of the radio frequency signal meet the preset condition, that is, whether the antenna is in a healthy state is determined. In the wireless intercom system, the requirements of signal power and standing-wave ratio can be preset by a manager, and the wireless intercom system can normally operate under the condition of meeting the preset value; and when the preset value is not met, the equipment needs to be adjusted or maintained in time.
It should be noted that, in the process of determining the health state of the antenna, the used parameters include, but are not limited to, the powers of the uplink and downlink signals and the standing-wave ratio, and the parameters are selected only to be able to evaluate the health state of the antenna accordingly, which is not specifically limited in the present invention.
As shown in fig. 3, fig. 3 is another flowchart of a signal processing method according to an embodiment of the present invention. It can be understood that the signal processing method provided by the present invention further includes, but is not limited to, step S210 and step S310.
Step S210, obtaining radio frequency parameters and equipment information according to the radio frequency signals.
Step S310, sending the radio frequency parameter to the cloud server, so that the cloud server can manage the device according to the radio frequency parameter and the device information.
It can be understood that, when the radio frequency parameters are obtained according to the radio frequency signals, the system can also obtain the device information according to the radio frequency signals, and send the device information to the cloud server, so that the cloud server can maintain and manage the wireless intercom system by combining the radio frequency parameters and the device information.
It should be noted that the device information includes, but is not limited to, information of an initiator, a call attribute, and a relay station of the radio frequency signal. Specifically, the initiator of the radio frequency signal refers to an initial initiator of the uplink and downlink radio frequency signals, and may be represented in the device information as an ID of an interphone sending the signal; the conversation attribute refers to whether the conversation initiated at this time belongs to single call, group call or full call; a relay station refers to which relay stations are passed through during signal propagation.
As shown in fig. 4 and fig. 5, fig. 4 is a flowchart of a signal processing method according to an embodiment of the present invention, and fig. 5 is a schematic structural diagram of a wireless intercom system according to an embodiment of the present invention. It is understood that the signal processing method provided by the present invention further includes, but is not limited to, step S510, step S520, step S530, step S540, and step S550.
Step S510, acquiring a radio frequency signal.
Step S520, obtaining the power of the uplink and downlink rf signals and the standing-wave ratio of the downlink signal according to the rf signal.
Step S530, judging whether the standing-wave ratio and the power meet the design requirements.
Step S540, transcoding the analog signal in the radio frequency signal into a digital signal, and extracting the device information in the digital signal.
And step S550, sending the signal power, the standing-wave ratio and the equipment information to a cloud server.
It is understood that the wireless intercom system shown in this embodiment includes a power detection module 110, a protocol decoding chip 120, a main control MCU module 130, an antenna 140 and an IP network card 150. After step S510 is executed to obtain the rf signal, the power detection module 110 executes step S520 to measure the signal power and the standing-wave ratio of the uplink and downlink rf signals received by the antenna 140 according to the rf signal, and executes step S530 to determine whether the standing-wave ratio and the power satisfy the predetermined requirement value. If not, directly executing step S550, and sending the signal power and the standing-wave ratio to the cloud server through the main control MCU module 130, so that the cloud server performs maintenance and management on the devices in the system according to the parameter indexes; if the design requirement is met, step S540 is executed to transcode the radio frequency signal into a digital signal through the protocol decoding chip 120, and extract the device information in the digital signal. The device information includes, but is not limited to, information of an initiator, a call attribute, and a relay station of the radio frequency signal. After the device information is obtained, step S550 is executed, the signal power, the standing-wave ratio and the device information are integrated by the main control MCU module 130, and the integrated signal power, the standing-wave ratio and the device information are sent to the cloud server. The cloud server can sense the radio frequency parameters and the equipment information in the system, so that the equipment in the wireless intercom system is managed, each piece of equipment in the system is ensured to be in a normal state, and the equipment management capacity and the emergency command capacity of the wireless intercom system are improved. The protocol decoding chip 120 shown in fig. 5 can sense the ID of the nearby interphone transmitting signals by using the antenna 140 in the present system, and further can determine that the interphone is within the signal coverage of the present antenna 140, so that the signal strength ranging model and the detected signal strength value can be used to perform calculation, and finally obtain the approximate distance between the interphone and the antenna 140.
It should be noted that before the main control MCU module 130 sends the device information and the radio frequency parameters to the cloud server, the data is further taken as a payload according to a communication protocol and is encrypted, and then the data is sent to the cloud server through the IP network card 150 by using a TCP/IP protocol. The data is encrypted, so that information leakage is prevented, and the safety of the system is improved.
In the process of applying the wireless intercom system, technicians and users of the intercom system cannot sense the signal coverage condition of the antennas 140 distributed in the building, and only when the signals of the interphones cannot be sent out or received, the technicians and users of the intercom system can recognize that the nearby antennas 140 have a fault condition. This problem, if it occurs in emergency rescue situations, can have catastrophic consequences. Therefore, by using the wireless intercom system provided by the invention, the uplink and downlink signal conditions of each antenna 140 in the system, whether the signal coverage meets the design and use requirements, whether the antenna has abnormal data and the like can be known in real time, so that the maintenance and management of the wireless intercom system are more convenient.
