step S101, after receiving the network access command broadcasted by the near-end machine and transmitted by the bus type feeder line, detecting the RSSI value of the monitored bus type feeder line.
In this embodiment, the near-end unit is connected to multiple remote units through a bus-type feeder line, specifically, each of the near-end unit and the remote units is additionally provided with a Sub-1G wireless SOC for transceiving a control signal, where the wireless SOC is assigned with a unique MAC address, in this embodiment, the transmitted signal is a radio frequency signal, and the near-end unit or the remote unit transmits control information by transmitting a GFSK modulated signal on the bus-type feeder line. In the networking process, the near-end machine combines a frequency shift signal and a control signal corresponding to a network access instruction into one path through a multi-system and multi-path Platform (POI), then transmits the path to an indoor distribution feeder along a bus type feeder, and transmits the path to a corresponding far-end machine through a coupler.
In this embodiment, the remote access method is implemented with a remote access as an execution subject, where the remote access belongs to networking equipment that needs to be installed for access in an indoor distribution system, and after the remote access is installed for the first time, the remote access does not need to be re-accessed under the condition that the access is not updated subsequently; in this embodiment, although the remote machine is an execution subject of the remote machine network access method, after the near-end machine sends the network access instruction, the remote machine performs the request for network access and authentication, that is, after the near-end machine initiates network access, the remote machine starts to perform the step of network access.
In this embodiment, the near-end machine broadcasts and sends all network access instructions when initiating network access, and in this embodiment, all network access instructions broadcast and sent by the near-end machine carry a local physical address (MAC address) of the near-end machine, and after receiving the network access instructions, all remote-end machines linked to the bus-type feeder start to monitor and detect a Received Signal Strength Indicator (RSSI) value on the bus-type feeder.
And step S102, determining whether a channel linked by the remote terminal and the near-end machine in the bus type feeder is occupied or not according to the RSSI value.

In this embodiment, although all the remote terminals start monitoring the RSSI value on the bus-type feeder after receiving the network access command, all the remote terminals first check whether the channel is occupied. When the channel is not occupied, all remote terminals will contend for the channel and send a network access request, because of the difference of the distribution of the remote terminals, the remote terminals contend for the channel in sequence, and the remote terminals contend for the channel first access the network, that is, the completion of the network access of all the remote terminals is completed in sequence.

In this embodiment, when it is determined that the signal is not occupied, the remote terminal contending for the channel first sends the verification data to the near-end terminal, and the near-end terminal verifies the verification data after receiving the verification data to generate a corresponding verification result; in this embodiment, parameter data of the remote terminal in the verification data sent by the remote terminal to the near-end machine is an MAC address of the remote terminal, and the verification data further includes an address of the near-end machine, where the verification data further carries the MAC address of the near-end machine, and is used to verify that the remote terminal is the remote terminal that has received the network access instruction of the near-end machine; the parameter data of the remote machine is used for determining the remote machine corresponding to the check result sent by the near-end machine, namely after the near-end machine determines the check result, the check result is replied to the remote machine corresponding to the MAC address based on the MAC address of the remote machine in the received check data, and the network access request is used for representing the remote machine to request to access the network.
And step S104, determining a network access result according to the verification result.
In this embodiment, the verification result includes a verification pass and a verification failure, and when the remote terminal receives the verification result that the verification passes, it indicates that the remote terminal permits network access, and the network access of the remote terminal is completed; when the remote machine receives the verification result of the verification failure, the verification data transmitted by the remote machine is invalid, the remote machine fails to access the network, and the remote machine re-executes the network access after waiting for the second preset time; in this embodiment, the second predetermined time is a wait time randomly generated locally by the remote terminal.
Through the steps S101 to S104, after receiving the network access instruction broadcasted by the near-end unit and transmitted through the bus-type feeder, detecting the monitored RSSI value of the bus-type feeder; determining whether a channel linked by a remote terminal and a near-end machine in the bus type feeder is occupied or not according to the RSSI value; under the condition that the channel is determined to be unoccupied, sending verification data to the near-end machine, and receiving a verification result generated by verifying the verification data sent by the near-end machine, wherein the verification data at least comprises a network access request and parameter data of the far-end machine, and the parameter data of the far-end machine is used for determining the far-end machine corresponding to the verification result sent by the near-end machine; the network access result is determined according to the verification result, the problem that the remote terminals are difficult to access in batches when the remote terminals are installed for the first time in the multi-device networking process of the wireless coverage system applied to the high-density application scene in the related technology is solved, the beneficial effects that the remote terminals access in batches and the remote terminals recognize accurately are achieved, and meanwhile, the transmission of control signals in the radio frequency feeder is achieved.
In some embodiments, determining whether a channel linked to the remote unit and the near-end unit in the bus-type feeder is occupied according to the RSSI value comprises the following steps:
step 1, obtaining a plurality of RSSI values of a bus-type feeder line monitored in a first preset time, wherein the first preset time comprises the time from a near-end machine broadcasting a network access instruction to a far-end machine completing network access.
In this embodiment, the remote terminal is configured to detect the RSSI on the bus-type feeder line within a first preset time, so that a plurality of RSSI values are detected within the first preset time.
And 2, judging whether the RSSI values exceed a preset threshold value or not.
And 3, determining that a channel linked by the remote terminal and the near-end machine in the bus type feeder line is unoccupied under the condition that the RSSI values do not exceed the preset threshold value.
In this embodiment, if the RSSI value is continuously maintained below the preset threshold value within the first preset time, it indicates that the channel is occupied, and the corresponding remote terminal may transmit the check data.
Acquiring a plurality of RSSI values of the bus type feeder line monitored within first preset time through the steps; judging whether the RSSI values exceed a preset threshold value or not; under the condition that a plurality of RSSI values do not exceed a preset threshold value, determining that a channel linked with a near-end machine in a bus type feeder line is unoccupied, and realizing the verification of whether the channel is available, thereby effectively identifying when the far-end machine accesses the network and improving the accuracy and efficiency of accessing the network by the far-end machine.
In some of these embodiments, the following steps are also implemented: and under the condition that at least one RSSI value in the plurality of RSSI values exceeds a preset threshold value, determining that a channel linked with the far-end machine and the near-end machine in the bus type feeder line is occupied, and detecting the monitored RSSI value of the bus type feeder line after waiting for a second preset time.
In this embodiment, the second predetermined time is a waiting time randomly generated by the remote terminal; in this embodiment, if the remote terminal detects the RSSI value exceeding the preset threshold during the listening process, a random waiting time, i.e. a second preset time, is generated locally at the remote terminal, and after the waiting time is over, the remote terminal starts to detect the monitored RSSI value.
In the step, under the condition that at least one RSSI value in the plurality of RSSI values exceeds the preset threshold value, the channel linked by the remote terminal and the near-end machine in the bus type feeder line is determined to be occupied, and the monitored RSSI value of the bus type feeder line is detected after waiting for the second preset time, so that the occupied channel detection is realized, and the waste of operation resources generated by invalid monitoring detection is saved.
In some embodiments, the verification of the verification data by the near-end machine comprises the following steps:
step 1, the near-end machine verifies the verification data by adopting a preset verification mode to determine a verification result, wherein the preset verification mode comprises one of the following modes: parity check, cyclic redundancy check.
In this embodiment, the verification of the verification data is to check the integrity of the verification data, and does not include checking the identity of the remote terminal.
And 2, when the near-end machine verifies that the verification data are valid data, the near-end machine determines that the verification result is verification passing, wherein the valid data are the network access request, the parameter data of the far-end machine and the parameter data of the near-end machine carried in the network access instruction and are generated according to a preset format.
In this embodiment, the verification of the near-end machine on the verification data may be to verify whether the corresponding verification data is arranged according to a preset format, for example: whether the data are arranged according to the sequence of the parameter data of the near-end machine, the parameter data of the far-end machine and the enclosure request, if the verification data are valid, the data are arranged according to a preset format, and in the embodiment, the near-end machine does not check the identity of the far-end machine.
In this embodiment, when determining that the verification result is that the verification passes, the near-end machine replies an instruction that the corresponding remote-end machine determines to pass, so that the corresponding remote-end machine completes network access; after the corresponding remote machine completes network access, the near-end machine does not send an instruction, specifically, the near-end machine does not broadcast and send a network access instruction, at the moment, the channel has no related data, the channel is unoccupied, and at the moment, other remote machines which do not access the network are allowed to contend for the channel and accurately access the network.
And 3, when the near-end machine verifies that the verification data is invalid data, the near-end machine determines that the verification result is verification failure.
In this embodiment, when the near-end machine verifies that the verification data is invalid data, the corresponding verification data is deleted, and a verification failure of the far-end machine specifying the MAC address is replied, and the far-end machine cannot access the network temporarily.
Verifying the verification data by the near-end machine in the above steps in a preset verification mode to determine a verification result; when the near-end machine verifies that the verification data is valid data, the near-end machine determines that the verification result is verification passing; when the near-end machine verifies that the verification data is invalid data, the near-end machine determines that the verification result is verification failure, verification of the verification data is achieved, accurate identification of batch network access of the far-end machine is completed, and the problem that the far-end machine is difficult to identify when an indoor wireless distribution system installs the far-end machine in batches for the first time is solved.
In some embodiments, after the near-end machine determines that the verification result is a verification failure, the following steps are further performed: and after the near-end machine deletes the third preset time of the check data, detecting the monitored RSSI value of the bus type feeder line, wherein the third preset time comprises the time from the far-end machine to the far-end machine for sending the check data to the far-end machine until the far-end machine receives the check result.
In this embodiment, in the case of a failure in verification, the verification is restarted after a set time interval, so that it is ensured that the remote device can complete network access effectively and orderly.
In some embodiments, after the near-end machine determines that the verification result is verification pass and the far-end machine accesses the network, the following steps are further implemented: detecting whether the RSSI value of the effective data and the RSSI value of the detection bus type feeder line exceed a preset threshold value in the verification data within a fourth preset time; and under the conditions that valid data are not detected and the RSSI value does not exceed a preset threshold value, determining that all remote terminals linked with the bus type feeder line complete network access.
In this embodiment, in order to ensure that no remote terminal requests to access the network for a long enough time, the fourth preset time is set to be n times of the third preset time, where n ≧ 10.
In this embodiment, the near-end unit continuously monitors the channel within the fourth preset time, and if there is no valid data transmission on the channel and the RSSI value of the channel does not exceed the preset threshold all the time, it is determined that all the remote-end units complete network access.
In this embodiment, after all the remote terminals access the network, a monitoring mechanism for repeated confirmation is set, so that all the remote terminals to be installed and accessed to the network are ensured to access the network.
It should be noted that, after it is verified that all the remote terminals complete network access, if it is detected that the network-accessed remote terminals do not match the number of remote terminals to be installed, for example: and if the number of the remote machines to be networked is less than that of the remote machines to be installed, manually restarting the network access process, thereby enabling all the remote machines to be installed to be networked.
In the above steps, whether the RSSI value of the valid data and the RSSI value of the detection bus type feeder line exceed the preset threshold value is detected in the check data within the fourth preset time, and under the condition that the valid data is not detected and the RSSI value does not exceed the preset threshold value, it is determined that all remote terminals linked with the feeder line complete network access, so as to implement the judgment and detection for ending network access.
In some of these embodiments, the following steps are also performed:
step 1, after receiving a network access updating instruction sent by a near-end machine, acquiring first parameter information corresponding to the near-end machine carried in the network access updating instruction.
In this embodiment, the first parameter information includes a MAC address of the near-end machine; in this embodiment, when a new antenna is installed in an operating wireless network or a remote terminal that has accessed the network is installed in a network corresponding to another near-end machine, the remote terminal needs to be updated to access the network, at this time, the corresponding near-end machine broadcasts an access update instruction to the remote terminal that has been linked to the network and the remote terminal to be newly installed, and after receiving the access update instruction, the corresponding remote terminal analyzes the access update instruction, thereby reading the MAC address of the near-end machine.
And 2, detecting second parameter information in the first parameter information, wherein the second parameter information comprises preset and stored parameter information corresponding to the near-end machine.
