First, an implementation environment of the present invention is illustrated, and the present example is not limited to a specific device structure, but may implement a specific implementation environment of a technical solution of the present invention, and referring to fig. 1, fig. 1 is a schematic diagram of an implementation environment of an embodiment of the present invention, where a telemetry monitoring system includes a monitoring end 20, a cloud end 30, a first telemetry end 10, and a second telemetry end 40. The first telemetry terminal 10 is provided with a first radio frequency module 11, a first call key 12 and a second call key 13; the monitoring end 20 is provided with a receiver 21 and a central machine 22, the central machine 22 is connected with the receiver 21, and the receiver 21 comprises a second radio frequency module 211 and a third radio frequency module 212; the second telemetry end 40 includes a fourth radio frequency module 41.

It should be noted that the receiver 21 further includes an audio interface, and is connected to the central unit 22 through the audio interface.

It should be noted that, the first telemetry terminal 10 and the second telemetry terminal 40 in this embodiment are two of the plurality of telemetry terminals in the telemetry monitoring system, the present embodiment does not limit the telemetry monitoring system to include only two telemetry terminals, but the multi-terminal interaction of the telemetry monitoring system is illustrated by taking the first telemetry terminal 10 and the second telemetry terminal 40 as an example of a scheme, and the description of the related descriptions of the first telemetry terminal 10 and the second telemetry terminal 40 is not repeated.

It should be noted that, the first call key 12 and the second call key 13 may be physical keys, or may be virtual keys in the touch display screen of the first telemetry terminal 10, which is not limited herein. Similarly, a third call key 42, similar in principle to the first call key 12, and a fourth call key 43, similar in principle to the second call key 13, may also be provided in the second telemetry terminal 40.

It should be noted that the rf modules of the first telemetry terminal 10, the second telemetry terminal 40 and the receiver 21 may have the same structure, and the difference is that the installed main bodies are different, and the related structures of the first rf module 11, the second rf module 211, the third rf module 212 and the fourth rf module 41 of the present embodiment are exemplarily described with reference to the schematic diagram of the rf module provided in fig. 2.

Referring to fig. 2, the radio frequency module may include a radio frequency chip, a radio frequency power amplifier, a reception matching and filtering module, a duplexer and filter, an antenna tuning matching module, and an antenna.

The radio frequency chip comprises a radio frequency transmitting and modulating module and a radio frequency receiving and demodulating module, wherein the radio frequency transmitting and modulating module is used for modulating input voice information into audio information, and the radio frequency receiving and demodulating module is used for demodulating the received audio information into the voice information. On this basis, a microphone and a speaker may be further disposed at the first telemetry terminal 10, the second telemetry terminal 40 and the monitoring terminal 20, the voice information is input to the radio frequency transmitting modulation module through the microphone, and the voice information demodulated by the radio frequency receiving demodulation module is played through the speaker. The audio power amplifier circuit can be additionally arranged at the front stage of the loudspeaker, so that the playing tone quality of the loudspeaker is improved.

The rf power amplifier is configured to amplify a modulated rf signal (e.g., an audio signal in this embodiment) to achieve a sufficient transmit power.

The receiving, matching and filtering module is used for ensuring that the input impedance of an amplifier in the radio frequency chip is matched when signals are received, and meanwhile, interference signals can be filtered to a certain extent.

The duplexer is used for receiving and transmitting simultaneously through one antenna and does not interfere with each other.

The antenna tuning matching module is used for matching the antenna impedance, reducing the standing wave ratio of the antenna and reducing the loss.

It should be noted that, the first telemetry terminal 10 and the second telemetry terminal 40 may also be provided with the same communication component, for example, as shown in fig. 1, where the first telemetry terminal 10 is provided with the first communication component 14, the second telemetry terminal 40 is provided with the second communication component 44, and the first telemetry terminal 10 establishes a network connection with the central machine 22 through the first communication component 14, so as to report the collected physiological parameter through a wireless network, and the second telemetry terminal 40 is similar.

It should be noted that, after the first telemetry terminal 10 in this embodiment presses the second call button 13, the target audio signal is sent through the larger target radio frequency, and in the case that the target radio frequency is sufficiently large, the receiving party of the target audio signal may be the external radio station 50, so that the first telemetry terminal 10 can send the distress information to the external radio station 50 through the target audio signal in the extreme case that the monitoring terminal 20 cannot be connected, thereby effectively improving the communication reliability of the telemetry monitoring system.

The control method according to the embodiment of the present invention will be further described based on the implementation environment shown in fig. 1 and the schematic diagram of the rf module shown in fig. 2.

Referring to fig. 3, fig. 3 is a flowchart of a communication method of a telemonitoring system according to an embodiment of the present invention, where the communication method of the telemonitoring system includes, but is not limited to, steps S10 and S20.

S10, when a first remote measuring end obtains a trigger signal of a first call key, a first intercom request is sent to a central machine, the central machine responds to the first intercom request and determines a first frequency pair from a preset channel frequency interval, the first remote measuring end and a receiver establish full duplex communication based on the first frequency pair, wherein the first frequency pair comprises a first radio frequency and a second radio frequency, the transmitting frequency of a first radio frequency module is the first radio frequency, and the transmitting frequency of the second radio frequency module is the second radio frequency.

It should be noted that, according to the description of the above implementation environment, the first telemetry side may set a first call key and a second call key, and trigger different intercom scenarios through different call keys. In the embodiment, after the trigger signal is generated by clicking the first call key, conventional intercom is established with the central machine so as to meet the daily intercom requirement.

It should be noted that, in the daily intercom scenario, the communication between the first telemetry end and the monitoring end may be considered normal, based on this, a channel frequency interval may be preset in the central unit, after the central unit obtains the first intercom request, a first frequency pair may be determined from the channel frequency interval, the first frequency pair is sent to the receiver and the first radio frequency module by means of a control command, the first radio frequency module sets the first radio frequency as a transmitting frequency, and sets the second radio frequency as a receiving frequency, and similarly, the receiver sets the transmitting frequency of the second radio frequency module as the second radio frequency, and sets the receiving frequency as the first radio frequency, so that a channel pair with different bidirectional frequencies is established between the receiver and the first telemetry end, the frequency occupied when the first radio frequency module sends the radio frequency signal is the first radio frequency, and the frequency occupied when the second radio frequency module sends the radio frequency signal is the second radio frequency, so that both sides do not interfere with each other, so as to implement full duplex communication.

The channel bandwidth required for voice intercom communication is typically only 12.5kHz or 25kHz, while for full duplex communication is only 2 times the bandwidth of the former (because of the two channels upstream and downstream), i.e., 25-50kHz is a pair of channels. Therefore, according to shannon's formula, in the whole telemetering and monitoring system under the same power, only need at least one receiver possess this second radio frequency module can satisfy the demand that requires full duplex communication.

It should be noted that, in this embodiment, the intercom between the first telemetry terminal and the central unit is full duplex communication based on the radio frequency module, and as known by those skilled in the art, the radio frequency signal may be a digital signal or an analog signal, so that when intercom is performed based on triggering of the first call key, the modulated audio signal may be an analog signal, for example, conventional FM modulation, or may be a digital signal, for example, DMR and P25 communication commonly used in digital intercom, and this embodiment does not limit the type of radio frequency signal of the intercom scene triggered based on the first call key.

S20, when the first telemetering terminal acquires a trigger signal of the second call key, the transmitting frequency of the first radio frequency module is switched to a preset target radio frequency, the target voice information is modulated into target audio information through the first radio frequency module, the target audio information is sent based on the target radio frequency, wherein the target radio frequency is larger than the maximum value of a channel frequency interval, the target voice information is preset or is input through the first telemetering terminal, and the target audio information is an analog signal.

It should be noted that, in this embodiment, under the condition that the first call key is provided to enable normal intercom to be established, the second call key is further provided at the first telemetry terminal, so that an emergency option can be provided for the first telemetry terminal. When the second call key is pressed, the transmitting frequency of the first radio frequency module is switched to a larger target radio frequency, the target radio frequency is not in a channel frequency interval, and when the first radio frequency module transmits a signal based on the target radio frequency, the first radio frequency module cannot be received by the second radio frequency module, but can send target audio information to the outside, for example, help calling can be achieved through the target audio information.

For example, the maximum value of the channel frequency interval is smaller than 400MHz, the target radio frequency is set to 438.5MHz of the radio station with the wave band of 0.7 mm, when a geological disaster is encountered, the monitoring end is usually disposed at a nurse station, communication is likely to be impossible due to power failure, at this time, a patient can switch the transmitting frequency of the first radio frequency module to the target radio frequency by clicking a second calling button, so that the target audio frequency information is sent to an external radio station for help calling, and the external help calling can be realized under the condition of communication interruption with the central machine.

It should be noted that, in this embodiment, the target audio information transmitted based on the target radio frequency belongs to emergency call, but is not normally talked, so after the second call key is triggered, the first radio frequency module unidirectional broadcasts the target audio information based on the target radio frequency, but does not establish talkback with the third terminal, based on this, the target audio information adopts an analog signal, and does not perform any encryption, so as to ensure that the target language information can be acquired and played by any receiving device capable of receiving the target radio frequency.

In the prior art, voIP is mainly adopted for intercom, and depends on wifi, bluetooth, LTE and the like, and processes of grouping, checking, encoding and decoding, error correction and the like are required, so that delay is easy to occur; the occupied bandwidth is large (hundreds of kHz), and the working frequency is relatively high (1.8 GHz or 2.4 GHz). As known from shannon's formula, in the case of constant power, the communication distance is inversely proportional to the channel bandwidth and the carrier frequency, which means that power consumption increases in the case of higher operating frequency. Through the technical scheme of the embodiment, full duplex intercom can be performed through the radio frequency module, delay is low, bandwidth occupation is only required to be tens of kHz, and system power consumption is effectively reduced; the interaction of the radio frequency modules does not need to depend on a communication network, and the configuration of the first radio frequency module is automatically completed by the first telemetry terminal based on the first frequency pair issued by the central machine, so that the first radio frequency module and the second radio frequency module are automatically allocated and establish full duplex communication, and the influence of network coverage on intercom quality is effectively avoided; meanwhile, when the central machine cannot communicate due to geological disasters, broadcasting of the target audio information can be triggered through the second calling key of the first telemetry terminal, unidirectional help calling is achieved, and communication reliability of the first telemetry terminal is further improved.

In one embodiment, referring to fig. 4, in step S10, the first telemetry side and the receiver establish full duplex communication based on the first frequency pair, and specifically includes, but is not limited to, the following steps:

s21, when first voice information is input through a first telemetry end, the first radio frequency module converts the first voice information into first audio information and sends the first audio information to the second radio frequency module so that the second radio frequency module analyzes the first voice information based on the first audio information;

S22, when the receiver acquires the second voice information, the second voice information is converted into second audio information through the second radio frequency module, and the second audio information is sent to the first radio frequency module, so that the first radio frequency module analyzes the second voice information based on the second audio information.

It should be noted that, the first voice information may be input to the radio frequency transmitting modulation module through the microphone shown in fig. 2, modulated into the transmittable first audio information through the radio frequency transmitting modulation module, and transmitted to the second radio frequency module through the antenna, and demodulated after the radio frequency receiving demodulation module of the second radio frequency module obtains the first audio information, so as to obtain the same first voice information.

It should be noted that, the second voice information acquired by the receiver may be input through the microphone of the monitoring end, or may be sent to the central machine from the cloud end, and then input to the receiver by the central machine, specifically, may be adjusted according to the intercom object. When the receiver acquires the second voice information, the second voice information is modulated and transmitted in the same way as the first voice information.

It should be noted that, the communication mode of this embodiment is full duplex communication, and the first audio information and the second audio information may be received and transmitted simultaneously, and the working frequencies of the two may be different and may not be interfered.

In addition, in an embodiment, referring to fig. 4, in step S10, after the first telemetry side and the receiver establish full duplex communication based on the first frequency pair, the method further includes, but is not limited to, the steps of:

S31, the central machine determines a target intercom object based on the first intercom request, wherein the target intercom object is a cloud end, a monitoring end or a second telemetering end;

S32, when the target intercom object is a monitoring end, the central machine is switched to an intercom state;

S33, when the target intercom object is the cloud end or the second telemetering end, the intercom audio between the target intercom object and the first telemetering end is transferred through the central machine.

It should be noted that, the telemetry monitoring system generally includes a plurality of telemetry terminals, and in this embodiment, the talkback object may be selected by the talkback request, and when the target talkback object is a cloud, the talkback between the patient and the cloud doctor may be achieved, and remote consultation, monitoring, etc. may be achieved; when the target intercom object is a monitoring end, the intercom between the nurse station and the patient can be realized, and the in-hospital monitoring can be realized; when the talkback object is the second telemetry terminal, the talkback between patients can be realized.

It should be noted that, the first intercom request may be configured through selection of the first telemetry end, for example, a display of the first telemetry end displays a plurality of available intercom objects, the first intercom request is generated after a target intercom object is selected by means of touch control or key, etc., the first intercom request carries the target intercom object, and the central machine executes corresponding communication establishment operation after determining the target intercom object based on the first intercom request.

It should be noted that, when the target intercom object is the monitoring end, since the first intercom request is received by the monitoring end, the central machine is only required to be switched to the intercom state to be connected and to establish intercom with the first telemetry end. After the central machine is switched to the talkback state, a first frequency pair is sent to the receiver and the first monitoring end, so that the second radio frequency module and the first radio frequency module can establish a channel pair of full duplex communication based on the first frequency pair.

It should be noted that, because the first telemetry terminal talkbacks through the radio frequency module, connection cannot be directly established with the cloud end, and the second telemetry terminal is worn on the body of other patients, if a plurality of telemetry terminals are allowed to directly establish talkbacks, more talkback channels are easily occupied, and normal monitoring talkback is affected.

In addition, in an embodiment, when the target intercom target is a cloud, referring to fig. 4, step S31 specifically further includes, but is not limited to, the following steps:

S311, when the second radio frequency module analyzes the first voice information, the first voice information is output to the central machine through the audio interface, and the central machine sends the first voice information to the cloud;

S312, when the central machine acquires the second voice information sent by the cloud, the second voice information is sent to the receiver through the audio interface.

It should be noted that, the receiver belongs to a component of the monitoring end, and the receiver and the central machine belong to mutually independent components, so as to realize the transmission of voice and audio signals.

It should be noted that, when the target intercom object is a cloud end, the central machine only needs to transfer intercom voice between the cloud end and the first telemetry end. The receiver demodulates the voice information and outputs the voice information to the central machine through the audio interface, and the central machine generates the voice information and also outputs the voice information to the receiver through the audio interface.

In addition, in an embodiment, when the target intercom target is the second telemetry terminal, referring to fig. 4, in step S33, intercom voice between the target intercom target and the first telemetry terminal is relayed through the central machine, and the method specifically includes, but is not limited to, the following steps:

S331, the central machine determines a second frequency pair from a channel frequency interval, the second telemetry end and the receiver establish full duplex communication based on the second frequency pair, wherein the second frequency pair comprises a third radio frequency and a fourth radio frequency, the transmitting frequency of the third radio frequency module is the third radio frequency, the transmitting frequency of the fourth radio frequency module is the fourth radio frequency, and the second frequency pair and the first frequency pair are not overlapped;

S332, when the second radio frequency module analyzes the first voice information, the third radio frequency module converts the first voice information into third audio information, and the third audio information is sent to the fourth radio frequency module, so that the fourth radio frequency module analyzes the first voice information based on the third audio information;

S333, when third voice information is input through the second telemetry terminal, the third voice information is converted into fourth audio information through the fourth radio frequency module, the fourth audio information is sent to the third radio frequency module, after the third radio frequency module analyzes the third voice information based on the fourth audio information, the second radio frequency module converts the third voice information into fifth audio information, and the fifth audio information is sent to the first radio frequency module, so that the first radio frequency module analyzes the third voice information based on the fifth audio information.

In the case of having a plurality of telemetry terminals, the receiver needs to add a third rf module in addition to the second rf module, and each rf module performs full duplex communication with one telemetry terminal.

It should be noted that, when the target intercom object is the second telemetry end, according to the above description, the full duplex intercom occupies the channel pair of the telemetry monitoring system, and if the two telemetry ends are allowed to directly perform radio frequency communication, it is likely that the central machine is not available for the intercom channel, so this embodiment only allows the intercom between the two telemetry ends to be established by using the central machine as the transit node.

It should be noted that, the central machine has already established full duplex communication with the first telemetry terminal based on the first frequency pair, and can transmit and receive audio information with the first telemetry terminal, so that it is necessary to further establish full duplex communication with the second telemetry terminal, and based on the principle similar to that of the first telemetry terminal, it is only necessary to perform corresponding configuration operation after determining the second frequency pair from the channel frequency pair. The second frequency pair is different from the first frequency pair by a certain frequency, for example, a difference of 5kHz between the radio frequencies.

It should be noted that, the communication between the monitoring end and the telemetry end is implemented based on the radio frequency module, and the central machine belongs to the transit node, but the second radio frequency module of the receiver also demodulates the received audio signal to obtain the voice signal, so the central machine does not directly forward the original signal sent by the first telemetry end, but demodulates and then remodulates and resends the original signal.

After the intercom of the first telemetry end and the second telemetry end is established, when the first telemetry end obtains first voice information, the first voice information is modulated into first audio information through the first radio frequency module and sent to the second radio frequency module, after the second radio frequency module obtains the first voice information, a target intercom object is determined to be the second telemetry end according to the configuration of the central machine, the receiver performs full duplex communication with the second telemetry end through the third radio frequency module, the demodulated first voice information is converted into third audio information through the third radio frequency module, the third audio information is sent to the fourth radio frequency module, and the fourth radio frequency module analyzes the first voice information based on the third audio information, so that the second telemetry end can play the first voice information input by the first telemetry end; the second telemetry side in step S333 sends the same voice to the first telemetry side, and the description thereof will not be repeated here.

In addition, in an embodiment, referring to fig. 4, after step S10 is performed, the following steps are included, but not limited to:

S41, a first signal type and a first encryption parameter are sent to a first telemetry terminal through a central machine, so that the receiver and the first telemetry terminal perform full duplex communication based on the first signal type and the first encryption parameter, wherein the first signal type is used for indicating audio information sent by a first radio frequency module and a second radio frequency module to be analog signals or digital signals, and the first encryption parameter is used for encrypting voice information generated during full duplex communication;

S42, when the target intercom object is a second telemetry end, a second signal type and a second encryption parameter are sent to the second telemetry end through the central machine, so that the receiver and the second telemetry end perform full duplex communication based on the second signal type and the second encryption parameter, wherein the second signal type is used for indicating that audio information sent by the third radio frequency module and the fourth radio frequency module is an analog signal or a digital signal, and the second encryption parameter is used for encrypting voice information generated during full duplex communication.

It should be noted that, based on the description of the above embodiment, the audio information sent by the radio frequency module is a radio frequency signal, and the radio frequency signal may be an analog signal or a digital signal, so that the type of the radio frequency signal is agreed by the first signal type when the full duplex communication is established in this embodiment, so as to ensure that the transceiving is consistent.

It should be noted that, for a monitored scenario, the intercom content generally relates to the illness state of the patient, and in order to protect the privacy of the patient, the embodiment configures the first encryption parameter when the intercom is based on the establishment, and the voice information is encrypted by the first telemetry terminal and the receiver by using the corresponding first encryption parameter. For the analog signal, the first encryption parameter can be a scrambling parameter, and the receiving and transmitting sides both adopt the same scrambling parameter, so that even if the external equipment accesses the same channel according to the receiving and transmitting frequency, only distorted sound can be heard, and the information safety is improved; similar logic may also be used to select a specific encryption algorithm for the digital signal, which is not limited in this embodiment.

It should be noted that, when the target intercom object is the second telemetry end, according to the description of the embodiment, the central machine demodulates the received audio information to obtain the voice information, and then remodulates the voice information to obtain the audio information according to the signal type and the encryption parameter of the opposite end, so that in the case of the transfer of the central machine, two signal encryption needs to be performed, the first telemetry end is used for transmitting the second telemetry end, for example, the first voice information is encrypted according to the first encryption parameter, then modulated into the first audio information based on the first signal type, at this time, the first audio information is encrypted, the second radio frequency module demodulates and decrypts the encrypted first voice information to obtain the first voice information, then encrypted based on the second encryption parameter, modulated into the third audio information based on the second signal type, and then transmitted to the fourth radio frequency module of the second telemetry end.

In addition, in an embodiment, referring to fig. 4, in step S31, the central unit determines a target intercom target based on the first intercom request, including:

S51, the central machine acquires and displays user information pre-associated with the first telemetry terminal;

S52, when the first intercom request carries the target equipment identifier, the central machine displays the target equipment identifier, and the indication object of the target equipment identifier is determined to be a target intercom object in response to the response trigger signal;

And S53, when the first intercom request does not carry the target equipment identifier, determining a target intercom object based on monitoring configuration information, wherein the monitoring configuration information is used for indicating that the current monitoring response object is a monitoring end or a cloud end.

It should be noted that, the central machine is usually disposed at the nurse station, and the user information corresponding to each telemetry end is pre-associated, so that the central machine can determine the pre-associated user information when acquiring the first intercom request, and ensure that the medical staff at the nurse station can know who initiates the intercom request by displaying the user information, thereby judging whether to allow intercom access. For example, when the first telemetry side requests to establish intercom with the central machine, it is usually allowed, and the first telemetry side requests to establish intercom with the second telemetry side, it is necessary for the medical staff to confirm whether intercom is necessary or whether another patient is disturbed, so that the embodiment provides a basis for determining to establish communication through the display of the user information and the target device identifier, and avoids establishing unnecessary intercom connection.

It should be noted that, the target device identifier may be description information of the device, for example, the description of the "central machine" directly through the target device identifier, or may be corresponding user information, for example, user information corresponding to the second telemetry end, where the specific form of the target device identifier is not limited in this embodiment.

It should be noted that, when the first talkback request does not carry the target device identifier, it may be considered that the first telemetry end request talkbacks with the default monitoring device, and in the telemetry monitoring system, the monitoring device may be a local monitoring end or a cloud end, so that the monitoring configuration information of each telemetry end is preconfigured, and the default monitoring party is determined according to the current monitoring configuration, so as to ensure that the first talkback request of the first telemetry end is responded.

When the first intercom request does not carry the target equipment identification, determining that the default monitoring equipment is a central machine through monitoring configuration information in working time, and establishing full duplex connection between the first telemetry terminal and the receiver; in the non-working time or in the temporary-away state of medical staff of the central machine, the default monitoring equipment can be determined to be the cloud end through monitoring configuration information, and intercom between the first remote measuring end and the cloud end is established based on transfer of the central machine, so that remote monitoring is realized.

In addition, in an embodiment, referring to fig. 4, in step S10, when the first telemetry side obtains the trigger signal of the first call key, a first intercom request is sent to the central machine, and the method specifically includes, but is not limited to, the following steps:

S61, after the first telemetry terminal is started, establishing network connection with the monitoring terminal, and reporting the acquired physiological parameters to the central machine based on the network connection;

s62, when a first telemetering terminal acquires a trigger signal of a first call key, a first intercom request is generated;

s63, the first intercom request is sent to the central machine based on the network connection.

It should be noted that, before the intercom between the first telemetry end and the monitoring end is implemented, the first telemetry end needs to upload the collected physiological parameters to the monitoring end, and the embodiment performs real-time reporting of the physiological parameters through the conventional network connection, and the specific method is a technology well known to those skilled in the art, and is not repeated herein.

It should be noted that, in this embodiment, the technical solution implements intercom through radio frequency communication, but before full duplex communication is established based on the first frequency pair, communication cannot be performed between radio frequency modules, so that a first intercom request cannot be initiated through a channel for intercom.

S71, recording intercom voice between the central machine and the first telemetry terminal to obtain recording voice information, and recording time information;

s72, the central machine stores the recorded voice information and the recorded time information as intercom records.

It should be noted that, the application scenario of this embodiment is telemetering monitoring intercom, and two parties of intercom are patient and medical staff generally, so after intercom is established according to the technical scheme of the embodiment, voice generated by intercom is recorded for subsequent use.

It should be noted that, through the technical scheme of this embodiment, the recording of the voice information does not need to intercept voice from the intercom channel, but directly stores the first voice information demodulated by the second radio frequency module as the recording voice information, determines the time when the first voice information is demodulated as the recording time information, and further stores the intercom record.

In addition, in an embodiment, referring to fig. 4, after step S20 is performed, the following steps are included, but not limited to:

s81, when the receiver and the first telemetry terminal successfully establish full duplex communication based on the first frequency pair, the first telemetry terminal sends target audio information to the receiver based on the first radio frequency;

s82, the network connection is in a maintenance state, and the first telemetry terminal sends target audio information to the central machine through the network connection.

It should be noted that, based on the description of the above embodiment, in a state that the central machine fails to work due to power outage, the second call key can transmit the target audio information to the outside with a larger transmitting power, and the first telemetry terminal does not need to consider communication with the central machine in order to realize help calling as soon as possible. After the help calling is completed, the embodiment can further try to communicate with the central machine, if the central machine resumes operation, the reestablished full duplex communication can be talked based on the first frequency, the target audio information is sent to the central machine as talkback content, and the target audio information can be sent through network connection under the condition of network recovery, so that internal help calling is realized, and communication efficiency and emergency processing efficiency are effectively improved.

In addition, in an embodiment, the receiver is further provided with a fifth rf module, where the receiving frequency of the fifth rf module is the target rf frequency, referring to fig. 4, step S20 further includes, but is not limited to, the following steps:

S91, broadcasting target audio information by the first telemetry terminal through the first radio frequency module;

and S92, when the receiver acquires the target audio information based on the fifth radio frequency module, demodulating the target voice information based on the target audio information.

It should be noted that, according to the description of the above embodiment, after the first telemetry terminal triggers the second call button, the target audio information is broadcast through the target radio frequency, and the target audio information is an unencrypted analog signal, so long as the receiving frequency is tuned to the target radio frequency, the target audio signal can be received. In order to realize the external call for help, the target radio frequency can be the frequency of the external radio station, so that the target radio frequency does not need to be temporarily determined by the central machine or the MCU of the first telemetry terminal, but is preset. In this embodiment, the fifth radio frequency module may be set in the receiver, and the receiving frequency of the fifth radio frequency module is set as the target radio frequency, so that after the first telemetry end discards the full duplex communication based on the first frequency pair, the central machine may still obtain the target audio information of the first telemetry end, demodulate and play the target voice information, and use the target radio frequency as the standby channel, thereby improving the communication reliability of the telemetry monitoring system. For example, the target voice information is used for prompting prompt information such as connection failure of the first call key.

s101, determining the signal strength of full duplex communication based on a first frequency pair through a central machine;

S102, when the signal intensity is lower than a preset intensity threshold, the central machine sends a switching instruction to the first telemetry terminal so that the first telemetry terminal switches the transmitting frequency of the first radio frequency module into a target radio frequency;

and S103, the central machine maintains voice intercom with the first telemetry terminal based on the fifth radio frequency module.

In the process of intercom between the central unit and the first telemetry end, the signal strength is related to the transmission power of the radio frequency signal and the transmission quality of the signal, and the first frequency determined based on the channel frequency interval may have more external interference, for example, more external communications use the same frequency. In the embodiment, the signal strength of full duplex communication is determined through the central machine, when the signal strength is lower than the strength threshold value, more interference on intercom can be determined, in order to improve intercom quality, the first telemetering terminal is controlled by the central machine to switch to the target radio frequency, meanwhile, the receiver starts the fifth radio frequency module with good receiving frequency configuration, intercom is maintained by utilizing the higher target radio frequency, and the communication quality of a telemetering monitoring system is ensured.

It should be noted that, the target radio frequency is preset in the first telemetry end and the fifth radio frequency module, so that half duplex communication can be established through the first radio frequency module and the fifth radio frequency module, and the communication can be maintained as an emergency channel.

In addition, in an embodiment, the telemetry monitoring system includes a plurality of available telemetry terminals, the monitoring terminal further includes a third call button, referring to fig. 4, the technical solution of the present embodiment further includes, but is not limited to, the following steps:

S111, when the central machine detects a trigger signal of a third call key under the state that the monitoring end and the available telemetry ends are not busy, determining at least one target call object from a plurality of available telemetry ends;

S112, the central machine determines at least one calling frequency pair from a channel frequency interval based on a preset frequency interval;

S113, sending second intercom requests to each target call object through a receiver, wherein each second intercom request carries different call frequency pairs;

s114, the receiver creates full duplex communication with the target call object based on the call frequency pair;

and S115, when the central machine acquires the broadcast voice information, converting the broadcast voice information into broadcast audio information through the second radio frequency module, and broadcasting the broadcast audio information to each target call object.

It should be noted that, based on the description of the foregoing embodiment, the receiver of the monitoring end is provided with the second radio frequency module and the third radio frequency module, and in the case of monitoring intercom, since the central machine has only one voice input end, in the case of one-to-one intercom, as long as full duplex communication is established according to the technical scheme of the foregoing embodiment, the monitoring end and the first telemetry end can be set to be in an occupied state, and the occupied state is cancelled after hang-up, so that other available telemetry ends are prevented from interfering intercom.

It should be noted that, besides the available telemetry end can call the monitoring end through the first call button, the monitoring end can also actively call the available telemetry end to perform one-to-many broadcasting, for example, medical staff can broadcast the prompt information related to monitoring to a plurality of patients at the same time, so as to improve the monitoring efficiency. The principle of modulating the broadcast audio information after the broadcast voice information is acquired is referred to the description of the above embodiment, and will not be repeated here.

It should be noted that, the central computer may display each available telemetry end, and the medical staff may select the target call object through the operation of the visual interface, and send a second intercom request to each target call object after acquiring the trigger signal of the third call key, so as to request to establish intercom. The second intercom request may refer to the first intercom request, and may be sent based on the network connection uploading the physiological parameter.

It should be noted that, although the motivation of the central machine to trigger the second intercom request may be broadcasting prompt voice, it is also necessary to consider the situation that the patient responds to the prompt information to carry out intercom with the nurse station, so in this embodiment, each second intercom request carries a different pair of call frequencies, and frequencies between each pair of call frequencies have a certain interval, for example, an interval of 5kHz, so that the central machine can establish a plurality of full duplex communications. For example, broadcasting voice information is used to prompt the patient to take a medication, but the patient's medication is either running out or not taken, and related information needs to be fed back to the nurse station through the corresponding telemetry terminal.

In addition, in an embodiment, the technical solution of the present embodiment further includes, but is not limited to, the following steps:

s121, the central machine determines at least one target prompt object from a plurality of available telemetry terminals based on a preset prompt configuration table and the current moment, wherein the prompt configuration table records prompt information and prompt moment corresponding to each available telemetry terminal;

s122, corresponding prompt information is sent to the target prompt object through the receiver.

Based on the description of the above embodiment, the central machine can be actively connected with the telemetry terminal in the telemetry monitoring system through the receiver, by using the principle, the present embodiment presets the prompt configuration table in the central machine, and records the prompt information and the corresponding prompt time of each available telemetry terminal through the prompt configuration table, thereby realizing the timing sending of the prompt information to the telemetry terminal, realizing the automatic monitoring, for example, the automatic monitoring can prompt the patient to take medicine at fixed time, or remind the patient to take part in the related examination at specific time, etc., and the present embodiment does not limit the prompt information.

The prompt message may be a pre-recorded voice, and the prompt configuration table is associated with a storage address of the corresponding voice; the prompt information may also be text information recorded in the prompt configuration table, and the voice broadcast is realized through a common text-to-voice function, which is not limited herein.
