Embodiment
The present invention will be further described below in conjunction with drawings and Examples.
The invention provides a kind of bypass control method of two-path bidirectional tower amplifier, comprise two-path bidirectional tower amplifier, it is characterized in that: the reception antenna of described amplifier is linked to each other with duplexer through radio-frequency (RF) switch respectively with transmitting antenna, described radio-frequency (RF) switch is controlled by the MCU of described amplifier, described MCU is connected with the fault detection unit circuit, and the alarm that described MCU handles comprises excess temperature alarm, standing wave alarm, power amplifier fault warning, LNA fault warning, power supply power-fail alarm, power failure alarm and overpower alarm.As shown in Figure 1, two-path bidirectional tower amplifier is that the BTS0 of equipment, BTS1 and MS0, MS1 are connected to base station mouth and antenna in the direct cascade mobile communication base station system, is connected to then on the port of radio-frequency (RF) switch.Just often base station signal is delivered to duplexer through BTS0, BTS1 when equipment work and carry out the uplink and downlink Signal Separation, the downstream signal of two links that will receive is again decayed by attenuator, meet the instructions for use of power amplifier with the signal that guarantees to enter power amplifier, amplify the back to duplexer through Multi-Carrier Power Amplifier again, deliver to the radio-frequency (RF) switch place after duplexer merges the uplink and downlink signal and launch to the overlay area through MS0, MS1 antenna.Upward signal then receives mobile phone signal by MS0 and MS1 respectively, goes out upward signal through radio-frequency (RF) switch one tunnel through diplexer separates earlier and delivers to the base station after low noise amplifier amplifies after duplexer closes the Lu Zaijing radio-frequency (RF) switch.Work as device fails, when switching, signal makes the equipment bypass through radio-frequency (RF) switch, to guarantee original network system operate as normal.
Each alarm of the present invention is adopted under the following mask body introduction mode and principle:
1, power supply power-fail alarm: after the power down of power supply externally fed, by-pass switch switches at once, does not recover initiatively to report the power supply power-fail alarm after a period of time.After power supply power-fail recovered, by-pass switch switched, and equipment recovers operate as normal.This alarm is finished for power supply, and it is high level or low level that the time of alarming more than occurring is uploaded to monitoring program, and monitoring program is resolved.
2, power failure alarm: power supply switches to bypass condition after having one internal fault takes place at once, does not recover initiatively to report the power supply power-fail alarm after a period of time.Behind the power fail recovery, report power up, equipment recovers normal operating conditions.This alarm is finished for power supply, and it is high level or low level that the time of alarming more than occurring is uploaded to monitoring program, and monitoring program is resolved.
3, descending power amplifier fault warning: when descending power amplifier produced fault, power amplifier can be uploaded fault warning information, opened the control bypass and switched.Two-way is judged control respectively respectively, and the power amplifier alarm is eliminated, and system switches to normal operating conditions.Increase an input power in the input of power amplifier and detect (also having the attenuator need be to its numerical value that superposes accordingly in prime), output increases a power output and detects.The fault judgement foundation when input work inspection and power output compare, and increases Rule of judgment and judges whether to be fault.
4, descending power amplifier excess temperature alarm: when the power amplifier temperature reaches certain value (thresholding can be established), by-pass switch switches, and initiatively reports the alarm of power amplifier excess temperature; When temperature drops to certain value (thresholding can be established), by-pass switch switches, and equipment recovers operate as normal.This key is the power amplifier detected temperatures, middle increase in the merit inspection, the device of detected temperatures, because this device sensitivity is very high, the detected temperatures model reaches 40 ~ 120 degrees centigrade, detects numerical value more accurately, and compares with the threshold value of software set, the alarm of generation excess temperature, the temperature of resuming work.
5, up LNA fault warning: upload alarm and control bypass during up LNA fault, recover alarm and also switch back normal condition.Detect the current value in the LNA module of described amplifier, then in modular program at corresponding value, collect corresponding data, software program judges whether to produce fault.
6, remote reset: carry out remote reset by corresponding order, whether the back detection system that resets is normal, normally then works the undesired bypass condition that still switches to.When bypass appears in equipment, can general long-range resetting, system roll-back, treat to carry out again after every subsystem operation each partly mechanism judge.
7, power amplifier standing wave alarm bypass: when standing wave switches to bypass (thresholding can be established) during greater than threshold value.In power amplifier module, have and detect the standing wave value, when the standing wave value during greater than threshold value the control radio-frequency (RF) switch switch to bypass.
8, when input power during greater than certain value, the equipment bypass.Monitoring program can be imported the setting of overpower thresholding, and when power amplifier detects the input power value, software program is judged according to thresholding and is confirmed to be not bypass.
9, communication abnormality fault warning: when inter-module communication bypass condition takes place to switch to when unusual and initiatively reports communication abnormality, recover the back by-pass switch and switch, equipment recovery operate as normal.Behind the opening of device, monitoring program is carried out poll to each module, sends data, and each module is uploaded each module numerical value, if any a module can't the collection module data upload to monitoring program, be communication abnormality this moment.
10, line under-voltage alarm: after amplifier power supply was under-voltage, by-pass switch switched, and initiatively reported the line under-voltage alarm; After the fault recovery, by-pass switch switches, and equipment recovers operate as normal.This fault is a Switching Power Supply, and when output voltage during less than certain value, Switching Power Supply is from an alarm mouthful output high level, and to monitoring program MCU pin, monitoring program is gathered accordingly to it.
11, fan alarm: after the fan stall, by-pass switch switches, and initiatively reports the fan failure alarm simultaneously; After fan failure recovered, by-pass switch switched, and equipment recovers operate as normal (fan is optional).This partly alarm mode is the alarm line that fan carries, and the monitoring examination produced alarm when monitoring program was to its alarm cause for gossip then during fault.
12, shield other all bypass modes when power alarm (comprising power supply power-fail and power failure) bypass occurring.
Software flow of the present invention as shown in Figures 2 and 3.Here what deserves to be mentioned is that all bypass switch reasons of the present invention all can show and Long-distance Control at the liquid crystal panel of PC and equipment, maintain easily.Bypass in this equipment two-way link is switched, and two-way is control separately, and another road is switched on roadside road can also operate as normal.
