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 a complex signal amplification device. The main amplifier has large heat productivity and high failure rate. The failure of the trunk amplifier will cause the wireless signal in the nearby area not to be transmitted normally, and the interphone 4 cannot communicate normally.
Thus, there is a need for remote monitoring and real-time inspection of the main amplifier. The related technology is to monitor the trunk amplifier by using a feeder return detection method, and when a return feeder fault in a wireless intercom system occurs, 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 the radio frequency signals of each port of the trunk amplifier according to a preset period, and the step is 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, converts the strength value of the radio frequency signals into a voltage value and sends the voltage value to the main control board.
The voltages at the ports are respectively the forward voltage of a downlink signal input port of the trunk amplifier, the forward voltage and the reverse voltage of a downlink signal output port of the trunk amplifier and the forward voltage of an uplink signal output port of the trunk amplifier.
The uplink signal is transmitted by the interphone 4, and after being transmitted by the antenna of the interphone 4, the uplink signal sequentially passes through the trunk amplifier, the receiving and transmitting sharing unit and the splitter and is finally transmitted to the relay station.
The downlink signal is sent out by the relay station, passes through the combiner, the receiving and sending sharing unit, the trunk amplifier and finally reaches the interphone antenna.
The signal acquisition frequency corresponding to the preset period is 5400 times of acquiring radio frequency signals per second.
The trunk amplifier comprises a main control board and a main board, wherein AD voltage chips are arranged at a downlink signal input port, a downlink signal output port and an uplink signal output port of the trunk amplifier, and the AD voltage chips are AD8314/AD 8362. And the AD voltage chip is in communication connection with the main control panel. The AD voltage chip collects radio frequency signals at a port of the trunk amplifier, converts the strength of the collected radio frequency signals into a voltage value and sends the voltage value 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 the timeliness of radio frequency signal monitoring is improved, and the signal condition can be conveniently and timely obtained.
The main control board supports TCP/IP network protocol and can support communication protocol of main board inside the trunk amplifier, such as RS 232.
Step S2, judging whether the strength value of the radio frequency signal is in the preset strength range of the radio frequency signal, and setting a variable a value according to the judgment result, wherein the specific steps are as follows:
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 the main control board;
step S22, comparing the voltage values corresponding to the radio frequency signals collected by the main control board in the calibration table to determine the strength values of the radio frequency signals corresponding to the voltage values;
step S23, judging whether the intensity value of the radio frequency signal is in the preset intensity range of the radio frequency signal;
step S24, if the strength value of the radio frequency signal is in the preset strength range of the radio frequency signal, the variable a is set to 1; otherwise 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 voltage of 0.2V is 25dBm, the signal power corresponding to the voltage of 0.3V is 26dBm, the signal power corresponding to the voltage of 0.4V is 27dBm, and the voltage value and the rf signal power value correspond to each other one to one. When the voltage value detected by the AD voltage chip is 0.3V, the power of the corresponding radio frequency signal is 26 dbm.
The predetermined signal strength range of the radio frequency signal at the downstream input of the main amplifier is-5 dbm to +8 dbm. 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 15 dbm.
For example, the AD voltage chip detects a voltage value corresponding to the radio frequency signal input in the downlink of the trunk amplifier, and compares the voltage value in the calibration table of the radio frequency signal intensity value and the voltage value to obtain an intensity value of the radio frequency signal input in the downlink of the trunk amplifier of-7 dbm, and if the intensity value is not within a preset signal intensity range of-5 dbm to +8dbm, the variable a is set to 0.
Referring to fig. 3, in step S3, the radio frequency signal information and the trunk amplifier information are combined into a data packet, the main control board sends the data packet to the debug terminal through the serial port, and adjusts the sent radio frequency signal according to the received adjustment command sent by the debug terminal, specifically:
step S31, detecting the communication state of the serial port and the network port of the main control board;
step S32, the main control board combines the radio frequency signal strength 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 into a data packet;
specifically, an uplink radio frequency signal path or a downlink radio frequency signal path is opened or closed through two switches respectively, and the on-off of the radio frequency signal path is adjusted; the corresponding radio frequency switch value is 1 or 0, the radio frequency signal path is opened to be 1, and the radio frequency signal path is closed to be 0.
The sizes of the uplink signal and the downlink signal are adjusted through the uplink attenuator and the downlink attenuator, and the amplitude of the radio frequency signal attenuation 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 signal 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 signal sent by the trunk amplifier according to the received adjusting command sent by the debugging terminal.
Specifically, the communication state of the serial port and the network port of the main control board is 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 data are stably and orderly transmitted, and the data transmission stability is improved. The debugging terminal obtains 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 the equipment information of the trunk amplifier according to the received command sent by the debugging terminal, which is specifically as follows:
and setting an Ip address, a port number, an MAC address, an uplink radio frequency switch value, a downlink radio frequency switch value, an uplink radio frequency attenuator setting value and a downlink radio frequency attenuator setting value of the trunk amplifier through the serial port.
Specifically, the debugging terminal stores an Ip address, a port number, an MAC address, an uplink radio frequency switch value, a downlink radio frequency switch value, an uplink radio frequency attenuator setting value and a downlink radio frequency attenuator setting value of the trunk amplifier into a calibration table of the strength 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 achieved, and preparation is made for communication between the trunk amplifier and equipment on a TCP network. The network chip is embedded in the main control board of the trunk amplifier, has an Ip network function, and can package an Ip data packet. The model number of the network chip is w 5500.
Step S5, the device status information, the signal gain information, and the control information are transmitted to the remote monitoring apparatus in TCP/IP packets.
The equipment state information comprises the temperature of the trunk amplifier, the forward radio frequency signal strength value of the downlink input port, the forward radio frequency signal strength value of the downlink output port, the reverse radio frequency signal strength value of the downlink output port, the forward radio frequency signal strength value of the uplink output port and a signal alarm byte.
The control information comprises an uplink radio frequency signal switch value, a downlink radio frequency signal switch value, an attenuation value of an attenuator of an uplink radio frequency signal and an attenuation value of an attenuator of a downlink radio frequency signal.
Specifically, based on the information of the trunk amplifier set in step 4, the remote monitoring device realizes remote monitoring of the trunk amplifier through the TCP/IP network.
The remote monitoring device remotely monitors the trunk amplifier through the TCP/IP network, does not rely on a radio frequency feeder line to transmit monitoring data, and uses the TCP/IP network 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 device of the wireless intercom system can still be effectively monitored and monitored under the condition of radio frequency link failure, and effectively fuse the information of all the devices to a remote monitoring device for comprehensive management.
Because the radio frequency feeder line relates to the problem of channel capacity, and voice communication is the highest priority of a wireless intercom system, byte quantity must be controlled by utilizing radio frequency feeder line transmission equipment monitoring information, the state of a remote trunk amplifier and the state of a radio frequency signal cannot be monitored in real time, and the monitoring information is transmitted through a TCP/IP network, so that the equipment and the signal state can be monitored at high frequency.
The trunk amplifier supports a TCP/IP network, the TCP/IP network is high in speed, and the trunk amplifier can quickly transmit equipment state information and radio frequency signal information to the remote monitoring device in time.
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 the 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 strength value of the radio frequency signal to adjust the strength of the radio frequency signal or prompt equipment failure, specifically:
step S71: if the strength value of the radio frequency signal is not in the preset strength range of the radio frequency signal, judging whether the strength value of the radio frequency signal is in an adjustable range;
step S72: and if the strength value of the radio frequency signal is within the adjustable range, the debugging terminal sends an adjusting command to the main control board.
In this embodiment, taking the downlink input radio frequency signal of the trunk amplifier as an example, the preset signal intensity range of the downlink input radio frequency signal of the trunk amplifier is-5 dbm to +8 dbm. The adjustable range of the radio frequency signal is-7 dbm to-5 dbm and 8dbm to 10dbm, i.e., within 2dbm outside of the preset signal strength range.
The strength value of the radio frequency signal at the downstream input of the trunk amplifier is-6 dbm. The variable a is set to 0 if the strength value-6 dbm of the radio frequency signal is not within the preset signal strength ranges-5 dbm and 8 dbm. The intensity value of the radio frequency signal is-6 dbm, which is within-7 dbm to-5 dbm of the adjustable range of the radio frequency signal. The trunk amplifier adjusts the strength of the transmitted radio frequency signal to be in the range of-5 dbm and 8 dbm.
Step S73: and if the strength value of the radio frequency signal is not in the adjustable range, the debugging terminal prompts equipment to be in fault.
And if the strength value of the radio frequency signal is in the unadjustable range, the debugging terminal prompts equipment to have a fault.
In this embodiment, the strength value-9 dbm of the radio frequency signal input downstream of the trunk amplifier is not within-7 dbm to-5 dbm of the adjustable range of the radio frequency signal. And the trunk amplifier sends equipment fault information to the debugging terminal to prompt the maintenance of the trunk amplifier.
The debugging terminal realizes the remote monitoring of the trunk amplifier and adjusts the radio frequency signal according to the detection result or carries out early warning on equipment failure in time. When the radio frequency signal is in the adjustable range, the signal is adjusted to be in the preset range. When equipment fails, the system gives an alarm in time to prompt equipment maintenance, so that the trunk amplifier on each node can stably transmit signals, and the remote management of the trunk amplifier and radio frequency signals is realized.
