Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings 1 to 6 and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The wireless intercom system has a plurality of devices, a plurality of radio frequency nodes and high requirements of radio frequency signals on a wired transmission line, and in order to monitor the signal state in the network, the nodes are required to solve the signal monitoring problem. The trunk amplifier is an important node for the uplink and downlink convergence of radio frequency signals, realizes the amplification function of the uplink and downlink radio frequency signals and is complex signal amplification equipment. The main line amplifier has large heating value and higher fault rate. Failure of the trunk amplifier will cause the wireless signal in the vicinity to be not normally transmitted, and the intercom 4 will not be able to communicate normally.
Thus, there is a need for remote monitoring and real-time inspection of the trunk amplifier. The related art is to monitor the trunk amplifier by using a feedback detection method of the feeder line, and when encountering a feedback feeder line fault in the wireless intercom system, the monitoring capability of the trunk amplifier is affected.
Example 1
Referring to fig. 1 and 2, the present embodiment provides a trunk amplifier management method, including the steps of:
step S1, the main control board collects voltage values corresponding to radio frequency signals of all ports of the trunk amplifier according to a preset period, wherein the voltage values are specifically as follows: the AD voltage chip collects radio frequency signals at a downlink signal input port, a downlink signal output port and an uplink signal output port of the trunk amplifier according to a preset period, and converts the intensity value of the radio frequency signals into a voltage value to be sent to the main control board.
The voltages at the ports are respectively forward voltage of a downstream signal input port of the trunk amplifier, forward voltage and reverse voltage of a downstream signal output port of the trunk amplifier and forward voltage of an upstream signal output port of the trunk amplifier.
The uplink signal is sent out by the interphone 4, and after being sent out by the antenna of the interphone 4, the uplink signal is sequentially sent to the relay station through the trunk amplifier, the receiving and sending sharing unit and the branching unit.
The downlink signal is sent out by the relay station, passes through the combiner, the receiving and transmitting sharing unit and the trunk amplifier, and finally reaches the interphone antenna.
The signal acquisition frequency corresponding to the preset period is 5400 times of radio frequency signal acquisition per second.
The main line amplifier comprises a main control board and a main board, and AD voltage chips are arranged at the downlink signal input port, the downlink signal output port and the uplink signal output port of the main line amplifier, and the model of the AD voltage chip is AD8314/AD8362. The AD voltage chip is in communication connection with the main control board. The AD voltage chip collects radio frequency signals at the port of the trunk amplifier, converts the intensity of the collected radio frequency signals into voltage values and sends the voltage values to the main control board, and the main control board monitors the radio frequency signals passing through the trunk amplifier in real time, so that timeliness of radio frequency signal monitoring is improved, and signal conditions can be acquired in time conveniently.
The main control board supports TCP/IP network protocol and can support communication protocol of main board inside trunk amplifier, such as RS232.
Step S2, judging whether the intensity value of the radio frequency signal is within the preset intensity range of the radio frequency signal, and setting a variable a value according to a judging result, wherein the method specifically comprises the following steps:
step S21, storing a calibration table of the intensity value and the voltage value of the radio frequency signal and the intensity range of the radio frequency signal on a main control board;
s22, comparing the voltage value corresponding to the radio frequency signal acquired by the main control board in the calibration table to determine the intensity value of the radio frequency signal corresponding to the voltage value;
step S23, judging whether the intensity value of the radio frequency signal is within the preset intensity range of the radio frequency signal;
step S24, if the intensity value of the radio frequency signal is within the preset intensity range of the radio frequency signal, the variable a is set to be 1; otherwise the variable a is set to 0.
In this embodiment, in the calibration table of the rf signal strength value and the voltage value, the signal power corresponding to the 0.2V voltage is 25dBm, the signal power corresponding to the 0.3V voltage is 26dBm, and the signal power corresponding to the 0.4V voltage is 27dBm, where the voltage value and the rf signal power value are in one-to-one correspondence. When the voltage value detected by the AD voltage chip is 0.3V, the power of the corresponding radio frequency signal is 26dbm.
The preset signal strength range of the radio frequency signal of the downlink input of the trunk amplifier is-5 dbm to +8dbm. The radio frequency signal strength of the downlink output of the trunk amplifier is required to reach 37dbm, so that the power of the radio frequency signal strength of the downlink output of the antenna of the interphone 4 is ensured to reach 15dbm.
For example, the voltage value corresponding to the radio frequency signal of the downlink input of the trunk amplifier detected by the AD voltage chip is compared in a calibration table of the radio frequency signal intensity value and the voltage value, so that the intensity value of the radio frequency signal of the downlink input of the trunk amplifier is-7 dbm, the intensity value is not in a preset signal intensity range of-5 dbm to +8dbm, and the variable a is set to 0.
Referring to fig. 3, step S3 is to form a data packet from the radio frequency signal information and the trunk amplifier information, send the data packet to the debug terminal through the serial port by the main control board, and adjust the sent radio frequency signal according to the received adjustment command sent by the debug terminal, specifically:
s31, detecting the communication state of a serial port and a network port of a main control board;
step S32, the main control board forms a data packet from the radio frequency signal intensity value, the uplink radio frequency switch value, the downlink radio frequency switch value, the uplink radio frequency attenuator setting value, the downlink radio frequency attenuator setting value, the variable a value, the MAC address, the Ip address and the port number of the main line amplifier;
specifically, an uplink radio frequency signal channel or a downlink radio frequency signal channel is respectively opened or closed through two switches, and the on-off of the radio frequency signal channel is regulated; the corresponding RF switch value is 1 or 0, the RF signal path is opened to 1, and the closing is 0.
The magnitude of the uplink and downlink signals is adjusted through the uplink and downlink attenuators, and the amplitude of the attenuation of the radio frequency signals is adjusted through the setting value of the uplink radio frequency attenuator and the setting value of the downlink radio frequency attenuator, so that the intensity of the radio frequency signals is adjusted.
Step S33, the main control board sends the data packet to the debugging terminal through the serial port;
and step S34, the main control board adjusts the radio frequency signals sent by the trunk amplifier according to the received adjustment command sent by the debugging terminal.
Specifically, the communication states of the serial port and the network port of the main control board are timely solved through detection, and when the serial port and the network port are in a normal communication state, the main control board can stably transmit data. The trunk amplifier forms the equipment information and the radio frequency signal information into a data packet, so that the data is stably and orderly transmitted, and the data transmission stability is improved. The debugging terminal acquires the data packet in a serial port communication mode, so that the monitoring of the trunk amplifier and the radio frequency signal is realized.
Step S4, setting equipment information of a trunk amplifier according to a received command sent by the debugging terminal, wherein the equipment information comprises the following specific steps:
the IP address, the port number, the MAC address, the uplink radio frequency switch value, the downlink radio frequency switch value, the uplink radio frequency attenuator set value and the downlink radio frequency attenuator set value of the trunk amplifier are set through the serial port.
Specifically, the debugging terminal stores the Ip address, the port number, the MAC address, the uplink radio frequency switch value, the downlink radio frequency switch value, the uplink radio frequency attenuator set value and the downlink radio frequency attenuator set value of the trunk amplifier into a calibration table of the intensity value and the voltage value of the radio frequency signal in a serial port communication mode, so that information setting of the trunk amplifier is realized, and preparation is made for communication between the trunk amplifier and equipment on a TCP network. The main control board of the trunk amplifier is embedded with a network chip which has an Ip network function and can package IP data packets. The network chip model is w5500.
And S5, transmitting the equipment state information, the signal gain information and the control information to a remote monitoring device in a TCP/IP data packet.
The equipment state information comprises the temperature of a trunk amplifier, a forward radio frequency signal intensity value of a downlink input port, a forward radio frequency signal intensity value of a downlink output port, a reverse radio frequency signal intensity value of the downlink output port, a forward radio frequency signal intensity value of an uplink output port and a signal alarm byte.
The control information comprises an uplink radio frequency signal switching value, a downlink radio frequency signal switching value, an attenuation value of an attenuator of the uplink radio frequency signal and an attenuation value of an attenuator of the downlink radio frequency signal.
Specifically, based on the information of the trunk amplifier set in the step 4, the remote monitoring device realizes remote monitoring of the trunk amplifier through a TCP/IP network.
The remote monitoring device remotely monitors the trunk amplifier through the TCP/IP network, and does not depend on the radio frequency feeder line to transmit monitoring data, but uses the TCP/IP network which is completely independent of the radio frequency network to realize the transmission of the monitoring data. The system and the method ensure that each trunk amplifier equipment of the wireless intercom system can still be effectively monitored under the condition of radio frequency link failure, and effectively integrate information of all equipment to a remote monitoring device for comprehensive management.
Because the radio frequency feeder relates to the problem of channel capacity, and the voice call is the highest priority of the wireless intercom system, the monitoring information of the equipment transmitted by the radio frequency feeder must control byte quantity, the state of the remote trunk amplifier and the state of the radio frequency signal cannot be monitored in real time, and the monitoring information is transmitted by the TCP/IP network, so that the states of the equipment and the signal can be monitored at high frequency.
The trunk amplifier supports a TCP/IP network, the TCP/IP network is fast, and the trunk amplifier can quickly and timely transmit equipment state information and radio frequency signal information to a remote monitoring device.
Example 2
Referring to fig. 4 and 5, the present embodiment provides a trunk amplifier management method, including the steps of:
step S6, the debugging terminal receives a data packet sent by the main control board;
step S7, the debugging terminal sends a command according to the value of the variable a and the intensity value of the radio frequency signal to adjust the intensity of the radio frequency signal or prompt equipment fault, specifically comprising the following steps:
step S71: if the intensity value of the radio frequency signal is not in the preset intensity range of the radio frequency signal, judging whether the intensity value of the radio frequency signal is in an adjustable range or not;
step S72: if the intensity value of the radio frequency signal is in an adjustable range, the debugging terminal sends an adjustment command to the main control board.
In this embodiment, taking the radio frequency signal input in the downstream of the trunk amplifier as an example, the preset signal strength range of the radio frequency signal input in the downstream of the trunk amplifier is-5 dbm to +8dbm. The adjustable range of the radio frequency signal is-7 dbm to-5 dbm and 8dbm to 10dbm, i.e., within 2dbm of the preset signal strength range.
The strength value of the radio frequency signal of the downstream input of the trunk amplifier is-6 dbm. The variable a is set to 0 if the intensity value of the radio frequency signal, 6dbm, is not within the preset signal intensity ranges, 5dbm and 8dbm. The strength value of the radio frequency signal is-6 dbm within the adjustable range of-7 dbm to-5 dbm of the radio frequency signal. The main amplifier adjusts the strength of the transmitted radio frequency signal to be in the range of-5 dbm and 8dbm.
Step S73: if the intensity value of the radio frequency signal is not in the adjustable range, the debugging terminal prompts equipment to fail.
If the intensity value of the radio frequency signal is in a non-adjustable range, the debugging terminal prompts equipment to fail.
In this embodiment, the strength value of the RF signal at the downstream input of the trunk amplifier is-9 dbm, which is not within the range of-7 dbm to-5 dbm of the RF signal. The trunk amplifier will send equipment failure information to the debug terminal prompting maintenance of the trunk amplifier.
The debugging terminal realizes remote monitoring of the trunk amplifier, and adjusts radio frequency signals according to detection results or timely early warns of equipment faults. When the radio frequency signal is in the adjustable range, the signal is adjusted to be in a preset range. When the equipment fails, the alarm is given in time to prompt equipment maintenance, ensure that the trunk amplifier on each node stably transmits signals, and realize remote management of the trunk amplifier and radio frequency signals.
