[0002] Traditional redundant control systems mostly rely on switch switching to achieve their goals. A power device in the related art includes two power amplifiers, one of which is a host and the other is a standby. When the host fails, the redundant system switches by controlling the switch to put the host into standby mode, and the standby is put into operation. Another power device consists of two hosts and a standby. If one of the two standby machines of the power device fails, the redundant system controls the switch switching so that the standby can be put into operation. Redundant control systems are generally designed for high-power devices, and for this purpose, the switches used at the output end of the redundant system must be able to withstand a large passing power. Such switches are generally double-pole double-throw waveguide switches. When the waveguide switch is not switching, its waveguide port will be blocked. This causes a short signal interruption during the switching process of the waveguide switch, resulting in a decrease in the stability of the power device. Therefore, there are still technical problems that need to be solved in the related art. Summary of the invention

[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings to illustrate the principles and processes of the continuous power system and communication device in the embodiments of the present invention.

[0035] Traditional redundant control systems mostly rely on switch switching. Figure 1 The traditional 1:1 redundant control system consists of two amplifiers, one of which is the main unit and the other is the backup unit. When the main unit fails, the redundant system switches the control switch to put the main unit into standby mode and the backup unit into operation. A similar 2:1 redundant control system refers to a redundant system with two main units and one backup unit. If one of the two backup units fails, the redundant system controls the switch to switch the backup unit into operation.

[0036] However, redundant control systems are generally designed for high-power equipment, so the switches used at the output end of the redundant system must be able to withstand a large amount of passing power. Such switches are generally double-pole double-throw waveguide switches. When the waveguide switch is not switching, the waveguide port will be blocked. This means that there will inevitably be a short signal interruption during the switching process. Therefore, there are still technical problems that need to be solved in the related art.

[0037] Reference Figure 2, the present application provides a continuous power system. The continuous power system may include a redundant subsystem 1, an amplitude module 2 and a phase module 3. The amplitude module 2 and the phase module 3 are connected to the redundant subsystem 1. The redundant subsystem 1 may include N power amplifier units. In one adjustment cycle, the amplitude module 2 and the phase module 3 input the input signal after amplitude and phase adjustment to the input end of the redundant subsystem 1 through a microstrip transmission line or a waveguide. After processing the input signal, the redundant subsystem 1 can output the maximum output power and generate a feedback signal. The feedback signal can be fed back to the amplitude module 2 and the phase module 3, and then in the next adjustment cycle, the amplitude module 2 and the phase module 3 can adjust the amplitude and phase of the signal input to the redundant subsystem 1 again according to the feedback signal.

[0038] When the power amplifiers of the redundant subsystem are working normally, the single-unit output power of each power amplifier is the first threshold. When i power amplifiers of the redundant subsystem fail, the output of the amplitude module and the phase module are adjusted, and the i power amplifiers are turned off, and the single-unit output power of Ni power amplifiers of the redundant subsystem is adjusted from the first threshold to the second threshold, so that the maximum output power of the redundant subsystem remains unchanged before and after the failure.

[0054] Furthermore, in some feasible embodiments of the present application, the maximum output power of the system is 63dBm.

[0055] Furthermore, in some feasible embodiments of the present application, the phase module includes an automatic gain adjustment unit and an automatic amplitude adjustment unit; the automatic gain adjustment unit and the automatic amplitude adjustment unit are connected to the redundant subsystem.

[0056] The specific calculation principle of this application is explained below with reference to the accompanying drawings:

[0057] As a power backup system, the continuous working system can be composed of multiple power amplifiers to achieve redundancy. When one of the continuous working system fails, the system can still work normally. Different from the traditional redundant system that relies on switches for redundant switching, the continuous working system does not contain any form of switch.

[0058] Reference Figure 5The continuous working system of this embodiment includes three functional modules: a redundant system, an amplitude module, and a phase module. The redundant system may include four power amplifiers, three power dividers, three Magic Tee synthesizers, three phase shifters, three couplers, three detectors, and six power loads. The redundant system mainly realizes the output of RF power. The amplitude module mainly controls the output power of the whole machine by controlling the adjustable attenuator in the power amplifier through the detection voltage of the power amplifier. The phase module is also called a phase modulation module, which is mainly used to realize phase matching in the redundant system.

[0059] Reference for the internal components of the redundant system Figure 6 As shown, in this embodiment, both the synthesizer and the power divider adopt the magic tee structure. The redundant system input is a transmission line, which can be a microstrip transmission line or a waveguide. The input power divider divides the input signal equally into two paths, or realizes four-way power division by composition. In the embodiment shown in the figure, a four-way power divider is used. After the signal is equally divided and distributed by the power divider, there are four branches. In order to achieve phase adjustment, at least N-1 terminal phase shifters are required. The phase shifter is a phase adjustment device, which mainly realizes phase adjustment by controlling its voltage, and the voltage is output by the phase adjustment module. In this embodiment, 3-way phase shifters are used to achieve phase adjustment. The four output ends of the power divider are respectively connected to the transmitter or the power amplifier. The output end of the transmitter or amplifier is connected to the isolator. In order to synthesize the power of the four outputs, a magic tee synthesizer that can pass high power is used for power synthesis. The number of synthesized paths is equal to the number of power division paths. In this embodiment, four-way synthesis is used, and the signal synthesis of each two paths uses a magic tee synthesizer. The Magic Tee synthesizer (hybrid synthesizer) has four ports, two of which are used to feed signals, the third port is used to synthesize the two fed signals, and the fourth port is an isolation port. All isolation ports of the Magic Tee synthesizer are terminated with high-power loads, and the high-power loads are equipped with coupling ports to feed the power fed into the load into the detector. The detector maps the fed RF power into a detection voltage. The detection voltage is fed back to the phase modulation module, and the phase modulation module adjusts the phase shifter according to the feedback detection voltage to achieve maximum power output.

[0060] The composition of the system amplitude module and phase module can be referred to Figures 7 to 9 .

[0061] The continuous power system output uses a binary Magic Tee synthesizer. In order to make the synthesizer at the highest power output under any circumstances, the signal fed into the synthesizer needs to be controlled by amplitude and phase. The amplitude control is completed by the amplitude module, which can be achieved by traditional AGC (automatic gain control) and ALC (automatic amplitude control), which will not be described here.

[0062] For automatic phase control, a phase modulation module is required to implement it. The phase modulation module of this embodiment controls Figure 7 As shown. The phase modulation module consists of two parts, a PI controller and a finite state switch. Since three phase shifters are used in this embodiment, there are three PI controllers.

[0063] Reference Figure 8 In fact, the finite state switch can be implemented using software or hardware circuits. The phase modulation process only needs to implement the following switching sequence, as follows Figure 7 The finite state switching steps are shown, including CalibrationOFF (calibration off), CalibrationON (calibration on), PhaseShitft1 (phase shifter 1 enabled), PhaseShitft1 (phase shifter 2 enabled), PhaseShitft1 (phase shifter 3 enabled), and JobsDone (calibration completed).

[0064] The finite state machine controls the enable signal so that different phase shifters are gradually turned on and off after a certain time interval, ultimately achieving independent operation of each phase shifter.

[0065] The phase adjustment module in this embodiment uses a PI controller to correct the error. Similarly, the phase error can also be adjusted by software. The core part of the PI controller is implemented by an operational amplifier, and a proportional amplifier and an integrator are connected in parallel, while the peripheral circuits include differential amplifiers, buffers and other circuits.

[0066] Reference Fig. 9 When the PI controller detects that Vdet is not equal to Vref (where Vref is usually not zero but the minimum voltage value that can be detected), the PI controller will adjust the voltage of the phase shifter until Vdet is close to or equal to Vref. As shown in the figure below, the adjustment process of the phase adjustment module of the system and the corresponding output power of the system at this time, the phase difference will decrease and the output power will increase as the phase adjustment process is executed.

[0067] Working principle of system phase modulation system

[0068] The output of the redundant system is binary power synthesis built by the Magic Tee synthesizer. Therefore, in order to achieve high synthesis efficiency, the two signals fed into the Magic Tee synthesizer are required to have the characteristics of equal amplitude and equal phase. However, in actual physical systems, there are no two signals with completely equal amplitude and equal phase, so the synthesis efficiency cannot reach the theoretical 100% synthesis efficiency. The synthesis efficiency is:

[0069] η=(1+2k×cos(Δθ)+k 2 ) / (2(1+k2 ))

[0070] Where Δθ=θ1-θ2 is the phase difference between the two feed ports, and k=P1 / P2 is the amplitude ratio of the two feed ports, in W. When there is an amplitude phase difference in the fed signal, the Magic Tee synthesizer is different from the 3-port T-junction. The power lost in the synthesis process of the 3-port T-junction will be reflected back along the two feed ports in the form of reflection. However, as a 4-port network, the lost power of the Magic Tee synthesizer will be fed into the fourth port of the Magic Tee synthesizer, the so-called isolation port. If the output port of the Magic Tee matches, the power fed into the isolation port is:

[0071] P iso =(P1+P2)(1-η)

[0072] Where η is the combined efficiency, P1 and P2 are the power amplitudes fed into the two input ports, in W. From the above formula, it can be seen that when the amplitude difference and phase difference are larger, the power Piso fed into the isolation port will be larger, and the two are directly proportional.

[0073] The isolation port of the Magic Tee synthesizer is cascaded with a load and a coupler, and the coupler couples the signal to the detector. In this embodiment, a logarithmic detector with a positive slope is used. However, the greater the input power, the greater the detection voltage Vdet. At this time, making the output synthesizer have the maximum synthesis efficiency is equivalent to minimizing the detection voltage of the isolation port of the Magic Tee synthesizer. Since this embodiment uses three Magic Tee synthesizers, maximizing the synthesis efficiency is also equivalent to all three Vdet reaching the minimum value.

[0074] In order to achieve the minimum value of the three Vdets, the three Vdets need to be independent parameters. That is, when one of the Vdets is adjusted, the other Vdets do not change. However, since only Vdet1 and Vdet2 are independent of each other, the control strategy of adjustment can be changed to first let Vdet1 and Vdet2 reach the minimum value, and then adjust Vdet3. In this embodiment, refer to Fig.10 , Vdet1 corresponds to power amplifier unit 2 and phase shifter 2. Vdet2 corresponds to power amplifier unit 4 and phase shifter 3. Vdet3 corresponds to phase shifter 1.

[0075] Please refer to the figure Figure 11-Figure 15 , the control logic of the continuous power system is as follows:

[0076] When there is phase mismatch and amplitude mismatch in the whole machine, the system starts the amplitude module and phase module respectively to match the amplitude and phase of the redundant system and the power synthesizer to achieve maximum power output.

[0077] When the continuous power system is put into use for the first time, or during the equipment replacement process, the system has the ability to self-calibrate. The so-called self-calibration is to start the amplitude module and phase module respectively through the system to match the amplitude and phase of the redundant system and the power synthesizer, so as to achieve maximum power output. In this embodiment, the output of a single power amplifier is 61dBm, and the maximum saturated output power of the system is greater than 66dBm (the synthesizer insertion loss is calculated as 1dB). When all four power amplifiers are operating normally, the four machines fall back 3dB output, that is, the output of a single machine is 58dBm, that is, the maximum output power of the system is 63dBm.

[0078] When one of the power amplifiers in the redundant system fails, the system shuts down the faulty machine. Since the synthesizer of the redundant system is equipped with an isolator, the synthesizer can still work in a matching environment. However, the shutdown of the faulty machine will cause a mismatch in the amplitude and phase of the entire synthesis system. Therefore, it is necessary to use the amplitude module and phase module of the continuous power system for adjustment. After the adjustment is completed, the system releases the output power limit of a single machine so that it can work at the saturated output power value of 61dBm for a single machine. Correspondingly, the continuous power system now works again at the maximum output power value of 63dBm. During this period, the output power of the continuous power system is not interrupted, but there is a short-term derating, which is the so-called "soft failure".

[0079] Compared with the traditional switch control redundant system, the "soft failure" and "self-recovery" of the continuous power system ensure that broadcasting and services are not interrupted, and the service quality is guaranteed.

[0080] In summary, this application has the following advantages:

[0081] 1. After a complete machine in the continuous power system of the present application fails, the system still has a high output power and can self-recover, so that broadcasting and services are not interrupted and service quality is guaranteed.

[0082] 2. The continuous power system of the present application includes an amplitude module and a phase module. The phase modulation module consists of two parts: a PI controller and a finite state switch. The amplitude module and the phase module work together to ensure that the synthesizer has the highest synthesis efficiency when a complete machine fails in the continuous power system, and ultimately ensure that the system still has a high output power when one power amplifier is damaged.
