Each wireless communication chip is externally connected with an antenna port and is used for realizing data interaction with the terminal through a wireless link in the downlink direction. The MCU-3 is connected with a preset Ethernet port (hereinafter referred to as Ethernet port) and is used for realizing data interaction with an upper computer through the Ethernet in the uplink direction. The ethernet communication protocol used for the ethernet is UDP (User Datagram Protocol ). The system further comprises an RCT clock for realizing the start and stop of each preset timer as shown in fig. 1b, and the following embodiments can be seen.
The data interaction between the wireless base station and the upper computer is used for at least realizing the configuration of the wireless base station, and a specific configuration flow comprises the following steps:
a1, after the wireless base station is powered on, the initial information sent by the upper computer is received through the communication receiver.
The initial information includes, but is not limited to, preset configuration information, and an initial call matching list.
In this embodiment, the preset configuration information includes at least frequency band configuration information, which is used to configure a communication frequency band of each device, where a communication frequency band corresponding to the target machine indicates a frequency band of the target machine for receiving or transmitting data. For example, the call transmitter corresponds to a first communication band, the call receiver corresponds to a second communication band, the communication transmitter corresponds to a third communication band, and the communication receiver corresponds to a fourth communication band.
The initial call matching list comprises information of preset terminals ordered according to preset call sequence positions in an initial state and a corresponding relation between the call sequence positions and a preset call period, wherein the preset terminals are terminals to be accessed to the network in the initial state, and the information comprises: identification information (i.e., ID), preset parameters, broadcast frequency, etc. It should be noted that, the correspondence between each terminal to be accessed to the network and the call sequence in the initial call matching list is preconfigured according to a preset rule, for example, the call sequence of the terminal to be accessed to the network is increased from small to large according to the ID of the terminal to be accessed to the network.
The communication receiver receives the initial information sent by the upper computer through the Ethernet port, and sends the initial information to the communication transmitter, the communication transmitter forwards the initial information to the call receiver, and the call receiver forwards the initial information to the call transmitter.

The present embodiment further specifically describes functions of a calling machine, a signaling machine, and a receiver with reference to fig. 1 to 4.
Fig. 2 is a flowchart for implementing specific functions of a calling machine according to an embodiment of the present application, where, as shown in fig. 2, the specific functional implementation flow of the calling machine includes:
s201, after powering up and waiting for a preset waiting time, initializing configuration is carried out.
In this embodiment, the initialization configuration of the calling machine includes:
1. reading initial information, configuring a communication frequency band according to preset configuration information, and acquiring and storing an initial call matching list.
In this embodiment, the initial information includes an initial call matching list and preset configuration information. Specific methods can be found in A1 to A3 above.
2. And carrying out variable and peripheral initialization.
In this embodiment, the calling machine variable and the peripheral initialization specifically include: UART (Universal Asynchronous Receiver/Transmitter, universal asynchronous receiver Transmitter), timer, SPI (serial peripheral interface ), and initialization of the first signaling chip.
It should be noted that, the specific method for initializing configuration may refer to the prior art, and this embodiment is not described in detail. The proposal powers on and waits for a preset waiting time period, and when initialization configuration is carried out, the proposal aims at waiting for the auto-negotiation of the network port part of the receiver and the completion of the initialization configuration of other machines (a communication transmitter and a communication receiver), thereby preventing the network access failure of the terminal caused by the fact that the signaling machine and the receiver are in an initialization state (namely, the initialization configuration is not completed) when the terminal network access request is received after the calling machine is powered on.
S202, the call transmitter responds to the starting moment of reaching the target call period, broadcasts a call packet through a first communication frequency band according to the call matching list, and starts a first timer to count from zero.
In this embodiment, the starting time of the target call period is a preset call time of the target call period, the call packet includes identification information of the target terminal, the target terminal is a terminal to be network-accessed and located in a target call sequence, and the target call sequence is a call sequence corresponding to the target call period. The call matching list comprises terminals to be accessed to the network, which are arranged according to preset call sequence positions, and the corresponding relation between each call sequence position and a preset call period.
It should be noted that, the call matching list in the initial state is an initial call matching list, and in the communication process, the call matching list is updated in real time in response to meeting a first preset updating condition, where the first preset updating condition includes: the call response packet satisfies a preset network access condition, or receives an offline instruction of any terminal, where the offline instruction at least includes identification information (specifically, as shown in fig. 1a, a target terminal ID sent by the signaling machine is received). For a specific method for updating the call matching list, see the following embodiments.
In this embodiment, the call transmitter broadcasts a call packet of the to-be-network-connected terminal located at a call sequence position corresponding to each preset call period at the start time of each preset call period, and calls the to-be-network-connected terminal, optionally, the call sequence position of the to-be-network-connected terminal is determined according to the size of the ID, for example, the call is gradually increased from small to large according to the ID of the to-be-network-connected terminal, and when the call arrives at the to-be-network-connected terminal with the largest ID, the call is restarted from the to-be-network-connected terminal with the smallest ID.
It should be noted that, the call transmitter determines the target terminal according to the call matching list through the MCU-1, and transmits a call packet in a broadcast form of wireless communication through the first signal transceiver chip, where the call packet can be received by terminals (such as the terminals 1 to n shown in fig. 1 a) within an arbitrary receiving range.
S203, if the first time duration does not reach the first preset time duration and the call receiver receives the call response packet, verifying whether the call response packet meets the preset network access condition.
In this embodiment, the first timing duration is a timing duration of the first timer, and the first preset duration is a preset duration of the target call period, for example, 10ms.
It should be noted that, the call response packet is sent by the call response terminal through the second communication frequency band in response to receiving the call packet, where the call response packet includes identification information of the call response terminal, and is used for requesting to access to the network. As shown in fig. 1a, taking a call answering terminal as an example of the terminal 1, after the terminal 1 receives the call packet, if the call packet includes its own identification information, the call answering packet is generated and sent through the second communication band.
In this embodiment, the preset network access conditions include:
1. the identification information of the call answering terminal is consistent with the identification information of the target terminal. It will be appreciated that if there is agreement, it means that the terminal requesting access to the network (i.e. the call answering terminal) is the terminal that is calling in the target call period of the radio base station.
2. Whether the application protocol of the call answering packet meets the preset protocol requirement or not.
And judging whether the application protocol of the call response packet meets the preset requirement according to the byte length of the received call response packet, whether the check codes are consistent and the coding rule of the data byte content. Specific application protocol authentication procedures can be seen in the prior art.
S204, if the call response packet meets the preset network access condition, the call receiver sends the network access instruction of the target terminal to the communication sender, and updates the call matching list.
In this embodiment, updating the call matching list includes deleting the identification information of the target terminal in the call matching list, and adjusting the call sequence of each terminal to be accessed to the network to obtain a first call matching list, where it is to be noted that the first call matching list will be used as a new call matching list.
It should be noted that, the call receiver receives the call response packet through the second signal transceiver chip, and sends the call response packet to the MCU-2 for verification.
S205, if the call response packet does not meet the preset network access condition, the call receiver discards the call response packet.
The call response packet which does not meet the preset network access condition is abandoned, which is equivalent to rejecting the network access request of the terminals except the terminal to be accessed which is called by the wireless base station, thereby improving the network access accuracy of the terminal and avoiding the poor reliability caused by the simultaneous network access of a plurality of terminals.
S206, returning to S202 if the first timing duration reaches the first preset duration.
It should be noted that, S202 to S206 are only processes (denoted as a first process) of calling a terminal to be connected to the network, and the calling machine calls the terminal to be connected to the network on the calling sequence bit corresponding to each calling period according to the first process at the start time of each calling period, that is, circularly calls the terminal to be connected to the network according to the calling sequence bit in the calling matching list, where the calling matching list is a calling matching list updated in real time in response to the first preset updating condition being satisfied.
As can be seen from the above technical solution, the calling machine provided by the embodiment of the present application includes: the call transmitter and the call receiver actively broadcast a call packet carrying the identification information of the target terminal according to the call matching list at the preset call moment reaching the target call period to realize sequential calling of the terminal to be accessed to the network, and the call response packet is transmitted by the call response terminal in response to the received call packet comprising the identification information of the call response terminal according to the call matching list. That is, when the call answering terminal determines to be called, the call answering packet is passively sent to request network access, so that the phenomena of channel conflict, packet collision and the like caused by the network access request of the terminal to be accessed simultaneously can be avoided, and the communication reliability of the wireless base station and the network access efficiency of the terminal are improved.
Fig. 3 is a flowchart of a specific function implementation of a signaling machine according to an embodiment of the present application, where the specific function implementation includes:
and S301, after power-up, initializing configuration is carried out.
In this embodiment, the method for initializing and configuring the signaling machine includes:
1. and reading the initial information, and configuring the communication frequency band according to the preset configuration information.
2. And carrying out variable and peripheral initialization.
In this embodiment, the signaling machine performs variable and peripheral initialization specifically includes: UART, timer, SPI and initialization of second signal receiving and transmitting chip. The specific method for initializing configuration may refer to the prior art, and this embodiment is not described in detail.
S302, acquiring a signaling list and judging whether the number of the network-accessed terminals is larger than 0 according to the signaling list.
Specifically, the signaling list includes identification information of the network-accessed terminals arranged according to preset query sequence bits, and a corresponding relation between each query sequence bit and a preset signaling period, and the network-accessed terminals include target terminals.
It should be noted that, the signaling list in the initial state is empty, and the signaling list is updated in real time in response to meeting a second preset updating condition, where the second preset updating condition includes: receiving an access command of any terminal (specifically, as shown in fig. 1a, receiving information of a target terminal sent by a calling machine), or receiving an offline command of any terminal (specifically, as shown in fig. 1a, receiving information of an offline terminal sent by a receiver). For a specific method for updating the call matching list, see the following embodiments.
It should be noted that, when the signaling list is empty, that is, the number of terminals already connected to the network is zero, the communication transmitter waits to receive the network connection instruction sent by the calling machine.
S303, if the number of the network-accessed terminals is greater than 0, traversing the signaling list, sequentially sending query packets to each network-accessed terminal, and starting a second timer to start timing from zero.
Specifically, the communication transmitter sequentially transmits the query packet to each network-entered terminal according to the query sequence bit in the signaling list. For example, the polling is increased from small to large according to the ID of the network-accessed terminal until the network-accessed terminal with the largest ID is polled.
Traversing the signaling list, and sequentially sending query packets to each network-entered terminal, wherein the process comprises the following steps:
s1, sending a query packet to an nth polling terminal, and starting a third timer to start timing from zero.
In this embodiment, the nth polling terminal is a network-accessed terminal with an inquiry sequence bit being the nth bit, where N is the number of network-accessed terminals and sequentially increases from 1 to N.
The query packet includes identification information of the query terminal, a broadcasting period, and a preset query instruction, wherein the preset query instruction includes a special flag for notifying the terminal of a query purpose, for example, a first special flag for notifying the terminal of an emergency alarm.
S2, responding to the third timing time to reach the third preset time, wherein N is smaller than N, replacing N with n+1, and returning to S1.
And S3, responding to the third timing time to reach the third preset time and n=N, and sending a polling mark packet to the receiver.
In this embodiment, the third time duration is a time duration of a third timer, the second time duration is a time duration of a second timer, the third preset time duration is a time duration of a preset signaling period of the polling terminal, and the second preset time duration is a time duration of a preset polling period.
The polling period at least comprises a preset signaling period of each network-accessed terminal. Specifically, in order to improve the reliability of polling, the present solution proposes a configuration method of a polling period as follows:
and acquiring a polling period according to the preset macro period, the preset gear parameter, the number of the terminals which are accessed to the network and the signaling period of each terminal which is accessed to the network. The specific method for calculating the polling period is as follows:
T send ＝(INT(total_num/max_num)+shift)*T macro
in the formula, T send Identifying the duration of the polling period, total_num representing the number of terminals that have been network-connected, max_num representing oneThe maximum number of terminals which can be carried in a preset macro period, max_num is determined according to the signaling period of each network access terminal and the preset macro period, shift represents a preset gear parameter, and T macro The duration of a preset macrocycle is indicated, INT being an upward rounding function. In general, the duration of the preset macro period is 1s, and as can be seen from the formula, in the initial state, the preset polling period is a macro period with the duration of 1s, according to the signaling period (for example, 10 ms) of each network-accessed terminal, the number of terminals that can be carried in one macro period of 1s in the signaling list has an upper limit capacity (i.e., max_num=100), and when the number exceeds the upper limit capacity, the preset polling period is immediately prolonged by one macro period, i.e., by 1s.
S304, in response to receiving the network access instruction, updating the signaling list.
Specifically, in response to receiving a network access instruction of the first target terminal, the identification information of the first target terminal is added into the signaling list, and the query sequence bit of the network accessed terminal in the signaling list is adjusted to finish updating the signaling list.
In this embodiment, the network access instruction of the first target terminal is sent by the call receiver in response to the call response packet including the identification information of the first target terminal meeting the preset network access condition, which is specifically referred to above embodiments.
S305, in response to receiving the offline instruction, updating the signaling list.
Specifically, the offline instruction of the second target terminal deletes the identification information of the second target terminal from the signaling list, adjusts the query sequence bit of the network-accessed terminal in the signaling list, and completes updating the signaling list.
