[0037] Passive distributed system (DAS) coverage refers to uniformly distributing the wireless signal output by the radio frequency remote unit (RRU) of the wireless network source equipment in the building through passive devices such as power dividers and couplers, so as to make the area where the user in the building resides have good wireless signal coverage.

[0039] Please refer to Figure 1 , Figure 1A schematic diagram of the low-power passive room state monitoring device is shown in the embodiments of the present application; as shown in Figure 1 The device comprises a directional coupler 101, a filter 102, a signal conversion module 103, a processor 104, a communication module 106 and a timer 106.

[0040] The first transmission line of the directional coupler 101 is connected in series with the feeder of the room-dividing antenna, and the second transmission line coupled with the directional coupler 101 and the first transmission line is connected with the filter 102; the signal output end of the filter 102 is connected with the signal conversion module 103, and the signal output end of the signal conversion module 103 is connected with the processor 104; the processor 104 is connected with the communication module 106 and the timer 106.

[0041] The directional coupler 101 is used to collect the radio frequency power signal in the feeder of the room-dividing antenna through the first transmission line, and couple the radio frequency power signal to the second transmission line, and transmit the radio frequency power signal to the filter 102 through the second transmission line.

[0042] The filter 102 is used to filter the radio frequency power signal to obtain the filtered radio frequency power signal sent to the signal conversion module 103.

[0043] The signal conversion module 103 is used to convert the filtered radio frequency power signal into a voltage signal and output the voltage signal to the processor 104.

[0044] The processor 104 is used to send a control signal and target information corresponding to the voltage signal to the communication module 106.

[0045] The communication module 106 is used to transmit the target information corresponding to the voltage signal to the first target server.

[0046] The timer 106 is used to send a wake-up signal to the processor 104.

[0047] In some embodiments, the signal conversion module is a detector.

[0048] In some embodiments, the processor, communication module and timer can be integrated, or can be separately arranged.

[0049] Integration means that the processor, communication module and timer are integrated in the same physical device or module, and the number of components is reduced through integrated design, the manufacturing cost is reduced, and the configuration, monitoring and maintenance are easier.

[0050] The processor, communication module and timer can also exist as independent components and be connected and communicated.

[0051] The processor, the communication module and the timer are integrated, which can be integrated by selecting the processor, the communication module and the timer, or selecting the existing module, such as the NB module.

[0052] When the processor, the communication module and the timer are realized by the NB module, the processor is a master control chip in the NB module, the timer is a timer in the NB module, and the communication module is a wireless signal transceiver module in the NB module.

[0053] The NB module, i.e. the NB-IoT module, is a hardware device specially used for Internet of Things communication, which realizes remote data transmission and communication between Internet of Things devices by using narrowband wireless communication technology; the NB-IoT module has the characteristics of low power consumption, wide coverage and low cost, and is suitable for various Internet of Things application scenarios.

[0054] The NB-IoT module is an integrated development type MCU, which can perform simple algorithm processing to calculate the radio frequency power and send information through an antenna.

[0055] The first transmission line of the directional coupler is connected in series in the feeder of the room-split antenna, and the radio frequency power signal in the feeder of the room-split antenna is collected through the first transmission line.

[0056] The directional coupler is a four-port element, which is usually composed of two sections of transmission lines, i.e. a straight-through line (main line) and a coupling line (secondary line); the working principle of the directional coupler is based on the coupling phenomenon of electromagnetic waves; when electromagnetic waves propagate in the transmission line, if the two transmission lines are close enough, the power on one line can be transmitted to the other line through the coupling mechanism.

[0057] Here, the first transmission line is the straight-through line (main line), and the second transmission line is the coupling line (secondary line).

[0058] In the embodiment of the application, the directional coupler is a 20dB coupler; the input end of the passive distributed system (DAS) introduces the directional coupler 20dB coupler for signal extraction, which minimizes the impact on the original coverage.

[0059] Moreover, when the low-power passive room-split state monitoring device is used to transform the existing passive distributed system (DAS), it is only necessary to break the feeder of the room-split antenna and connect the first transmission line of the directional coupler, which is very simple to replace and has low cost.

[0060] The second transmission line coupled with the directional coupler and the first transmission line is connected with a filter, the filter is specifically a band-pass filter, the signal output end of the filter is connected with a detector, and the detector is connected with a processor.

[0061] Please refer toFigure 2 , Figure 2 The circuit principle diagram of the directional coupler, filter and detector is shown in the embodiments of the application. Figure 3 , Figure 3 The circuit principle diagram of the processor is shown in the embodiments of the application.

[0062] For example, the filter is selected from a filter with an in-band insertion loss less than 3.5 dB and an out-of-band attenuation greater than 20 dB in a frequency range of 50 MHz-5300 MHz.

[0063] The coupled signal is filtered by the band-pass filter to avoid interference of other frequency bands on the detector.

[0064] Specifically, the filter sends the filtered radio frequency power signal to the detector, and the detector accurately converts the filtered radio frequency power signal into a corresponding logarithmic linear output, with a typical dynamic range of 45 dB and a logarithmic error less than ±1 dB; thereby performing power-level conversion on the filtered radio frequency power signal, converting the radio frequency power signal into a voltage value, and transmitting the voltage value to an ADC interface of an MCU integrated in the NB-IoT module.

[0065] The MCU integrated in the NB-IoT module calculates the radio frequency power after collecting the voltage value, and sends the radio frequency power through an antenna.

[0066] That is, the target information corresponding to the voltage signal includes the radio frequency power corresponding to the voltage signal.

[0067] In some embodiments, the target information corresponding to the voltage signal includes a voltage value corresponding to the voltage signal, a preliminary judgment result of the antenna fault based on the radio frequency power, and the like.

[0068] In some embodiments, the processor sends the radio frequency power to a first target server through the communication module (i.e., the NB module), and the first target server determines whether the node of the DAS system corresponding to the low-power passive room division state monitoring device is normal based on the radio frequency power, thereby realizing active sensing of the fault of the DAS system and realizing antenna device-level fault monitoring.

[0069] In some embodiments, the low-power passive room division state monitoring device further includes a power supply module, which includes a power supply and a voltage conversion circuit.

[0070] The voltage output end of the power supply is connected to the voltage conversion circuit, and the output end of the voltage conversion circuit supplies power to the signal conversion module, the processor, the communication module and the timer.

[0071] In some embodiments, the power supply module supplies power to the detector and the NB module.

[0072] The power supply is at least one of a battery, a voltage output terminal of a higher-level circuit, and a solar power supply; that is, a specific product can select a suitable power supply according to the model, installation location, and the like of the indoor antenna. The power supply can be powered independently or cooperatively, for example, designed as two lithium batteries or designed as two lithium batteries and a solar power supply cooperatively.

[0073] The battery is a dry battery and / or a rechargeable battery.

[0074] The rechargeable battery can be repeatedly charged and discharged and can be reused, and thus is more economical and environmentally friendly in the long term.

[0075] Since the timer sends a wake-up signal to the processor in a sleep state at a preset time point through timing, the processor in the sleep state is woken up, and the processor controls the communication module in the sleep state to enter a normal working mode. Therefore, the overall power of the low-power passive indoor split state monitoring device is very low; a disposable battery such as a lithium battery can provide long-time operation capability for the monitoring device, thereby reducing the need for frequent battery replacement and improving the reliability and maintenance convenience of the equipment.

[0076] It should be noted that when the NB module is selected to realize the functions of the processor, the communication module, and the timer, since the NB module can enter a low-power mode, the overall power of the low-power passive indoor split state monitoring device is very low.

[0077] The capacity of the rechargeable battery can be designed based on the power consumption of the NB module.

[0078] Please refer to Figure 4 , Figure 4 The circuit principle diagram of the power supply module described in the embodiments of the application is shown; please refer to Figure 5 , Figure 5 The circuit diagram of the power supply module described in the embodiments of the application is shown; as Figure 4 and Figure 5 The power supply module further includes a battery sampling circuit, a sampling end of the battery sampling circuit is connected to a voltage output terminal of the battery, and an output end of the battery sampling circuit is connected to a battery sampling end of the processor.

[0079] A switching circuit is arranged between the sampling end and the output end of the battery sampling circuit, the switching circuit is closed when the processor performs voltage sampling and is opened when the processor does not perform voltage sampling.

[0080] The battery sampling port of the processor collects a voltage signal of the power supply through the battery sampling circuit to perform battery state inquiry.

[0081] A switch circuit is arranged between the sampling end and the output end of the battery sampling circuit, and the switch circuit is closed when the processor is sampling voltage and is opened when the processor is not sampling voltage. Specifically, the switch circuit is connected to the switch control end of the processor. When the processor in the sleep state is woken up by the wake-up signal of the timer, the processor enters the normal working mode, and the processor controls the switch circuit to be turned on, so that the power supply state signal of the power supply module is collected by the battery sampling circuit.

[0082] When the processor enters the sleep state in response to the preset sleep condition being met, the processor controls the switch circuit to be turned off.

[0083] As shown in Figure 4 , the battery sampling circuit, which can also be referred to as a sampling and control circuit, realizes the functions of sampling and control.

[0084] The battery sampling circuit divides the battery voltage into a range (for example, a range of 1.6 V) of the ADC sampling voltage of the processor, and the switch circuit ensures that the voltage is cut off when not sampling, thereby avoiding leakage.

[0085] In the low-power passive room state monitoring device, the processor interacts with the first target server (background) through the communication module. Specifically, the SIM card module is arranged in the processor, and the communication with the first target server (background) is realized based on the SIM card module.

[0086] Please refer to Figure 6 , Figure 6 , which shows the circuit principle diagram of the SIM card module in the embodiment of the application; the Figure 6 is connected in parallel with two kinds of SIM cards, an eSIM card and a nano SIM card; the eSIM is an embedded SIM card, which can be directly integrated into a device without a physical SIM card slot; the nano SIM card is a physical card, which needs to be inserted into the SIM card slot of the device; in a specific product, one of them can be selected, and in the testing process, both kinds can be designed for testing, and the nano SIM card that can be inserted and removed during the testing process is more convenient for testing.

[0087] Please refer to Figure 7 , the network port connection indicator light is further arranged in the peripheral circuit of the processor; the network port connection indicator light can directly display the network connection status of the processor. When the indicator light is on, it usually indicates that the processor has successfully connected to the network; when the indicator light is off or flashing, it may indicate that there is a problem with the connection or that the connection is being attempted, thereby providing a basis for troubleshooting.

[0088] The processor receives instruction information sent by the background, configures the working mode of the processor based on the instruction information, and sends relevant data.

[0089] The instruction information sent by the background can be automatically sent according to a preset rule, or can be instruction information set according to customer requirements, for example, setting the next wake-up time based on customer requirements, setting the type of received information (for example, only receiving radio frequency power information this time), etc.

[0090] The working mode of the processor includes a normal working mode and a first switching condition thereof, a deep sleep mode and a second switching condition; for example, the normal working mode is started only twice a day, and the deep sleep mode (or deep sleep state) is in other time.

[0091] Specifically, the first switching condition is to receive a wake-up signal of a timer.

[0092] When the first switching condition is triggered, wake-up is started, the normal working mode is entered, a connection with a network management is established according to network management setting (for example, UDP), and power information of a room-dividing antenna is sent to a first target server, and then the deep sleep state is entered again; in the deep sleep state, all external control switches are in an off state, and a minimum power consumption state is reached.

[0093] According to network management setting (for example, UDP), a connection with a network management is established, and power information of a room-dividing antenna is sent to a first target server, and then the deep sleep state is entered again; specifically, according to network management setting (for example, UDP), a connection with a network management is established, and according to network management setting, a connection with a network management is established and power information of the room-dividing antenna is reported; after reporting, confirmation information returned by the network management is waited for; if the return is overdue (for example, the return time exceeds a preset threshold, and the preset threshold can be 3s), the sending is continued, and if there is no response after continuous sending for a preset number of times (for example, 3 times), the reporting fails and the sleep is entered.

[0094] If the network management response information is normally received, the sleep is entered after waiting for a timeout; if no network management information is received during the waiting process, the sleep is directly entered, and if network management setting information (for example, receiving battery data, radio frequency power data, etc.) is received, the setting is processed and stored, and then the sleep is entered again.

[0095] The low-power-consumption passive room-dividing state monitoring device described in the embodiments of the application can be designed integrally with the room-dividing antenna, or can be designed to be detachable; the directional coupler, the filter, the signal conversion module, the processor, the communication module and the timer are located inside or outside the room-dividing antenna, respectively.

[0096] That is, the filter in the device is located inside or outside the chamber antenna; the signal conversion module is located inside or outside the chamber antenna; the NB module is located inside or outside the chamber antenna; the directional coupler is located inside or outside the chamber antenna; the processor is located inside or outside the chamber antenna; the communication module is located inside or outside the chamber antenna; and the timer is located inside or outside the chamber antenna.

[0097] When the processor, the communication module and the timer are integrated (for example, using the NB module), the integrated processor, the communication module and the timer are located inside or outside the chamber antenna.

[0098] That is, the directional coupler, the filter, the detector and the processor, the communication module and the timer in the device can be independently installed inside or outside the chamber antenna, and can be flexibly arranged according to the type, structure, volume and the like of the chamber antenna.

[0099] In some embodiments, the directional coupler, the filter, the detector and the detector are packaged into an integrated device, and the integrated device is located inside or outside the chamber antenna, thereby reducing the number and complexity of devices, reducing installation and maintenance costs, and making the device more compact and convenient to install and use in limited space.
