In order to solve the technical problem of inaccurate self-excitation judgment in the prior art, the invention provides a signal communication terminal and a signal communication system.
In one embodiment, as shown in fig. 1, the signal communication terminal includes at least one set of signal enhancement branches and a routing circuit 50, where the routing circuit 50 is respectively connected to each signal enhancement branch and is configured to receive an uplink signal and send a downlink signal, and is configured to output a corresponding first switching signal and a corresponding second switching signal according to the downlink signal, the signal enhancement branches include a first antenna 10, a second antenna 60, a first switching circuit 20, a second switching circuit 40, a first signal distribution circuit 70, and a first signal processing circuit 30, the first switching circuit 20 is respectively connected to the first antenna 10, the second switching circuit, and the first signal processing circuit 30, the second switching circuit 40 is respectively connected to the first signal distribution circuit 70 and the routing circuit 50, and the first signal distribution circuit 70 is also connected to the second antenna.
The enhanced signal can be provided to the routing circuit 50 or the MIFI device connected to the second antenna 60, so that the technical problem that the network speed of the broadband network after the device for converting the mobile network into the broadband network in the weak mobile signal in the prior art is slow is solved.
For the case of weak wireless mobile signals, the end consumer may select a wireless signal enhancer to amplify signals, usually such as a repeater, man Gebao, and a mobile phone signal amplifier, where the signal enhancer is usually installed in a home, office, vehicle, market, subway, mountain area, etc., and the use of the signal enhancer to amplify signals can be considered as long as there is a place where the mobile signal is weak or even not. The basic principle is that the signal of the base station is received by the antenna at the BS (base station) end, amplified by the antenna at the first downlink branch and then transmitted by the antenna at the MS (mobile station) end to cover the area with weak signal, and the mobile phone signal in the area with weak signal received by the antenna at the MS end enters the uplink branch to be amplified by the antenna at the BS end and then transmitted to the base station.

The method has the further effects that the WIFI hot spot or the broadband network is provided in various scenes that the signal is strong or weak and even the signal cannot be searched, when the signal is strong, the signal enhancement function of the first signal processing circuit 30 can be closed to reduce power consumption, meanwhile, after the signal enhancer is bypassed, the mobile network is directly enabled to be converted into the broadband network to receive external signals, and therefore interference of the signal enhancer to the routing circuit 50 and the base station in the strong signal environment can be completely avoided. In addition, when the first signal processing circuit 30 has self-excitation, the first signal distribution circuit 70 can flexibly control to split the first uplink component signal output to the routing circuit and the second uplink component signal output to the next day, so as to realize the purpose that the signal communication terminal can work normally under the condition of self-excitation.

At this time, the signal processing circuit 30 of multiple frequency bands can be realized, and the combiner serves as a branch of different frequency bands.
The principles of the present invention are described below with reference to fig. 1-7:
Description of the scheme for the downstream signal:
As shown in fig. 1-2, the diplexer separates the received signal into an Uplink (UL) band and a Downlink (DL) band, down to an amplifier 34 (this location is typically a low noise amplifier LNA to ensure a good noise figure or signal-to-noise ratio, to ensure that the desired signal can be amplified instead of the background noise in the case where the BS antenna receives a weak or poor signal-to-noise ratio);
The signals are transmitted to the attenuator 33 after passing through the amplifier 34 and the duplexer 21 after passing through the amplifier 35, then the signals are transmitted to the second antenna through the coupler 1, and the amplified downlink signals transmitted by the second antenna can be provided for mobile communication terminals such as mobile phones and the like. There may be more than amplifier 4, possibly 2 or more amplifiers between the diplexer 20 and the diplexer 21, this being adjusted according to how much gain is required for the product, the same applies for the uplink;
The detection of the downlink signal by the detector 8 will typically detect the signal at a point in the downlink that is anywhere between the attenuator 33 and the diplexer 21. The detector 8 converts the detected signal into a signal (typically a voltage) that can be processed by a processor, and the processor generates a control signal to control the attenuation value of the attenuator 33 by processing the signal of the detector, so as to control the downlink signal, typically controlling parameters such as the signal strength and interference of the downlink, and typically preventing the signal from being too strong or reducing the interference. The detector is usually a detection diode or a logarithmic detector, and the processor is usually a microprocessor such as a singlechip, an FPGA, a CPU or the like or an analog negative feedback control circuit, and a plurality of attenuators, amplifiers, filters or other devices can be arranged on the amplifying link according to specific product requirements;
Generally, when the signal is weak or no interference is detected by the detector 8, the processor controls the attenuator 33 to release the attenuation value to the maximum, when the signal is strong or interference is detected by the processor, the processor controls the attenuator 33 to attenuate the gain until the signal is reduced to the normal range or the interference is eliminated or improved, and the control of the amplifying link is a common control technique of the boost, which is not described herein.
The signal distribution circuit is used for dividing the radio frequency signal into two parts or more parts according to the actual requirement of the product according to a certain proportion, one part of the radio frequency signal is sent to the second antenna, the other part of the radio frequency signal is sent to the switch 40 and then to the routing circuit, the signal distribution port can be a device or a module which is provided with the radio frequency signal distribution function independently and can be a combination of the devices, and the two signals can be distributed by the signal distribution circuit in a fixed proportion or in a proportion-adjustable mode. In this block diagram, the coupler 1 and the attenuator 34 form an adjustable signal distribution circuit, where the coupler has three ports, two ports are directly connected to each other, and one port is a coupled port, where the loss of the port that is usually directly connected is small, and the coupled port can only couple a small portion of signals through a large portion of signals, so that the effect of signal distribution is formed, and at the same time, the signals of the coupled port of the coupler in the block diagram 2 continue to pass through the adjustable attenuator 34, where the attenuation value of the adjustable attenuator 34 is controlled by the processor 3, and the processor can adjust the attenuation value of the attenuator 34 according to the actual requirement of the product, so that the signals that pass through the attenuator 34 are correspondingly attenuated, and the effect that signals reaching the routing circuit or the routing circuit are flexibly distributed is realized.
Meanwhile, the attenuation control of the attenuator 34 can also be directly or indirectly controlled by a routing circuit, wherein the routing circuit judges the received downlink signal intensity, if the received downlink signal intensity is too strong, the routing circuit controls the attenuator 34 to increase more attenuation values and reduce the received signal intensity, if the received downlink signal intensity is too weak, the routing circuit controls the attenuator 34 to decrease more attenuation values and increase the received signal intensity, and the routing circuit can also send the received signal intensity or the judging result to a processor, and the processor indirectly controls the attenuation of the attenuator 34.
When the first antenna and the second antenna are excited due to insufficient isolation of the two antennas caused by improper installation or environmental change, etc., then the device detects the excitation and attenuates the gain to eliminate the excitation, the attenuation values of the attenuator 32 and the attenuator 33 are larger at this time, so that the transmitting and receiving capability of the second antenna is weakened, the signal coverage effect of the second antenna is weakened, but at this time, the attenuation value of the attenuator 34 can still be reduced to offset or weaken the influence of the larger attenuation values of the attenuator 32 and the attenuator 33.
Scheme description for uplink signal:
in fig. 2, after the uplink transmission signal of the mobile communication device such as a mobile phone is received by the second antenna, the uplink transmission signal passes through the coupler and then goes to the duplexer 21 and then to the amplifier 33 (the amplifier after the duplexer is usually a low noise amplifier LNA to ensure that the noise factor or the signal-to-noise ratio of the signal received by the second antenna is not significantly deteriorated, so that the noise factor or the signal-to-noise ratio of the signal received by the second antenna is not significantly deteriorated, and thus the signal is not interfered by the base station after being amplified by the subsequent amplifying link of the LNA and then transmitted through the first antenna), the signal after being amplified by the amplifier 33 goes to the attenuator 32 (the amplifier 32 is usually a power amplifier PA), and the amplifier 32 is used for amplifying the signal to a sufficient power and passing through the duplexer 20 and then going through the antenna switching module and then to the first antenna and being transmitted and received by the base station;
The detector 7 detects the uplink signal and converts the uplink signal into a signal that can be processed by the processor, and the processor processes or analyzes the signal and generates a control signal, controls the attenuator 32 to adjust the link parameter, and the specific control manner and link description are the same as those of the downlink description, and are not repeated here;
Meanwhile, the routing circuit also generates an uplink transmission signal, then the uplink transmission signal reaches the attenuator 34, reaches the coupler 1 after passing through the attenuator, is coupled to a line between the coupler 1 and the duplexer 21, and then reaches the first antenna to be transmitted and received by the base station after the uplink transmission signal together with the uplink transmission signal of mobile communication equipment such as a mobile phone and the like reaches the duplexer 21 and passes through the same processing flow as the previous uplink signal.
In order to solve the above problems, the present invention also proposes a signal communication system, a base station, a mobile terminal, a routing terminal and a signal communication terminal as described above.
Wherein the signal communication system base station communicates with the first antenna 10 of the signal communication terminal, the mobile terminal communicates with the second antenna 60, and the routing terminal communicates with the routing circuit 50.
