Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to specific embodiments and the accompanying drawings.
It should be noted that technical terms or scientific terms used in the embodiments of the present application should have a general meaning as understood by those having ordinary skill in the art to which the present application belongs, unless otherwise defined. The use of "first," "second," and similar terms in the embodiments of the present application is not intended to indicate any order, quantity, or importance, but rather is used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
In view of this, an embodiment of the present application provides a communication method based on an LoRa gateway, as shown in fig. 1, the method includes:
step S101, receiving a message sent through a first channel and/or a second channel. In specific implementation, the LoRa gateway establishes communication connection with the first channel and the second channel at the same time.
Step S102, the messages are processed according to a preset sequence, wherein the communication protocols adopted by the first channel and the second channel are different. In specific implementation, in order to receive messages transmitted by using different communication protocols, different receivers may be set at the LoRa gateway, and all the receivers together form the LoRa gateway; the preset sequence is determined according to the actual requirement of the channel, for example, if the message sent through the first channel needs to be processed first, the preset sequence is that the first channel precedes the second channel, and vice versa.
The method provided by the application provides different channels for message transmission, and the LoRa gateway can distinguish messages sent from different channels according to different communication protocols.
In a specific implementation, the number of the first channels and the second channels is not limited, and may be set according to actual requirements, for example, when there are multiple message sending terminals, a corresponding number of channels may be set to receive messages.
In some embodiments, the communication protocol of the first channel is a standard protocol and the communication protocol of the second channel is a private protocol. In a more specific embodiment, the standard protocol is LoRaWAN.
LoRaWAN is a set of communication protocol and system architecture based on LoRa long-distance communication technology matched design, usually in star topology layout, and the gateway is connected to the network server through standard IP. The protocol and service of the upper layer of the LoRa private protocol are defined by self, the transmission rate and the transmission distance have matched self-adaptive algorithms, and the LoRaWAN can be distinguished, so that the LoRa gateway can distinguish messages sent from different channels, the same frequency interference can be effectively avoided, and the transmission safety and the system capacity are improved.
In some embodiments, before the step S102, the method further comprises:
step S1011, mark the message sent by the first channel as a first message, and mark the message sent by the second channel as a second message. Because the first channel and the second channel adopt different communication protocols, the gateway can distinguish different channels according to IP, upper layer protocols, services and the like of different communication protocols, thereby endowing different marks to messages sent through different channels.
Step S1012, sequentially placing the first messages in a first queue created in advance according to the receiving order, and sequentially placing the second messages in a second queue created in advance according to the receiving order. In specific implementation, the first queue and the second queue are created in a memory of the gateway in advance.
The above steps S1011 and S1012 can implement different processing for different transmission channels and different reception time messages by classifying and sorting the messages transmitted by different channels, thereby implementing targeted processing for different messages.
In some embodiments, as shown in fig. 2, the step S102 includes:
in response to the second message being present in the second queue, performing step S201: and processing the second message in the second queue, and deleting the processed second message from the second queue. In specific implementation, if the gateway receives a second message sent by a second queue while processing a first message in the first queue, the gateway suspends the processing of the current first message, preferentially processes the second message, and when the processing of the second message is completed, if no other second message exists in the second queue, resumes the processing of the previously suspended first message; and if other second messages exist in the second queue, continuing to process the second messages.
In response to the second message not existing in the second queue, performing step S202: and processing the first message in the first queue, and deleting the processed first message from the first queue.
The above steps S201 and S202 can implement that the second message is always prior to the first message, and a first-come-first-come principle is applied to the messages transmitted through the same channel, and in practical applications, the important message can be set as the second message, so as to implement timely transmission and timely processing of the important message.
In a specific embodiment, in order to further ensure that the second message is processed preferentially, in step S101, when there is a message transmitted from the first channel and the second channel simultaneously, the message sent through the second channel is received preferentially.
In some embodiments, the first channel is a normal channel, the second channel is an alarm channel, the first message is a normal message, and the second message is an alarm message.
In practical application, the method provided by the embodiment can use the alarm channel/message as the second channel/message, can realize timely transmission and timely processing of the alarm message, and avoids property loss caused by the fact that the alarm message cannot be processed in time. In a specific embodiment, the second channel may also be a warning channel or an emergency channel, and the second message may also be a warning message or an emergency message.
It should be noted that the method of the embodiment of the present application may be executed by a single device, such as a computer or a server. The method of the embodiment can also be applied to a distributed scene and completed by the mutual cooperation of a plurality of devices. In this distributed scenario, one device of the multiple devices may only perform one or more steps of the method of the embodiment of the present application, and the multiple devices interact with each other to complete the method.
