All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment:
referring to fig. 1, a schematic structural diagram of an embodiment of the communication device for the logistics intelligent door lock provided by the invention is shown. As shown in fig. 1, the apparatus includes a GSM signal processing module 101, a LoRaWAN signal processing module 102, a GSM conversion module 103, a LoRaWAN conversion module 104, and a determination module 105.
And the GSM signal processing module 101 is configured to send a GSM signal to the GSM conversion module 103.
In this embodiment, the GSM signal processing module 101 includes a first network access request transmitting unit, a first signal processing unit, a first radio wave transmitter, a first receiver, a first wireless antenna, and a GSM signal transmitting unit.
The first network access request sending unit is used for sending the network access request signal to the first signal processing unit; the first signal processing unit is used for carrying out signal processing on the received network access request signal to obtain radio waves and sending the radio waves to the first radio wave transmitter and the first wireless antenna; a first radio wave transmitter and a first wireless antenna for transmitting radio waves to a base station; the first receiver and the first wireless antenna are also used for converting the response request electric wave sent by the base station into a digital signal and sending the digital signal to the GSM signal sending unit after the base station receives the radio wave; and a GSM signal sending unit, configured to send a GSM signal to the GSM conversion module 103 after receiving the digital signal. It should be noted that after the GSM signal sending unit receives the digital signal, the contact between the GSM signal processing module 101 and the base station is already established, once the GSM signal processing module 101 receives the mode enabling signal sent by the GSM conversion module 103, the GSM signal processing module 101 firstly communicates with the base station in any one of 2G/3G/4G communication modes, and secondly, the base station communicates with the cloud server through the mobile network, so that the information interaction between the logistics intelligent door lock and the cloud server is realized.
And the LoRaWAN signal processing module 102 is configured to send the LoRaWAN signal to the LoRaWAN conversion module 104.
In the present embodiment, the LoRaWAN signal processing module 102 includes a second network entry request transmitting unit, a second signal processing unit, a second radio wave transmitter, a second receiver, a second wireless antenna, and a LoRaWAN signal transmitting unit.
The second network access request sending unit is used for sending the network access request signal to the second signal processing unit; the second signal processing unit is used for carrying out signal processing on the received network access request signal to obtain radio waves and sending the radio waves to the second radio wave transmitter and the second wireless antenna; a second radio wave transmitter and a second wireless antenna for transmitting radio waves to the repeater; the second receiver and the second wireless antenna are also used for converting the response request electric wave sent by the repeater into a digital signal and sending the digital signal to the LoRaWAN signal sending unit after the repeater receives the wireless wave; and a LoRaWAN signal transmitting unit, configured to transmit the LoRaWAN signal to the LoRaWAN conversion module 104 after receiving the digital signal. It should be noted that after the LoRaWAN signal sending unit receives the digital signal, the connection between the LoRaWAN signal processing module 102 and the relay is already established, and once the LoRaWAN signal processing module 102 receives the mode enabling signal sent by the LoRaWAN conversion module 104, the LoRaWAN signal processing module 102 firstly communicates with the relay, and secondly, the relay communicates with the cloud server in a WiFi or 4G manner, so that information interaction between the logistics intelligent door lock and the cloud server is achieved.
The GSM conversion module 103 is configured to send a first connection request to the determination module 105 after receiving the GSM signal.
In this embodiment, the GSM conversion module 103 is further configured to receive the connection permission signal and the connection rejection signal sent by the determination module 105. When the GSM conversion module 103 receives the connection permission signal, it sends a mode enabling signal to the GSM signal processing module 101. After the GSM switching module 103 receives the connection rejection signal, the GSM switching module 103 prohibits sending the first connection request to the determining module 105 within 30 seconds; after 30 seconds, the GSM conversion module 103 starts sending the first connection request to the determination module 105.
And the LoRaWAN converting module 104 is configured to send a second connection request to the determining module 105 after receiving the LoRaWAN signal.
In this embodiment, the LoRaWAN converting module 104 is further configured to receive the connection permission signal and the connection rejection signal sent by the determining module 105. After receiving the connection permission signal, the LoRaWAN conversion module 104 sends a mode enable signal to the LoRaWAN signal processing module 102; after receiving the connection rejection signal, the LoRaWAN conversion module 104 prohibits sending the second connection request to the determination module 105 within 30 seconds; after 30 seconds, the LoRaWAN conversion module 104 starts sending the second connection request to the determination module 105.
And the judging module 105 is configured to receive and determine the current communication mode according to the first connection request and the second connection request.
In this embodiment, determining the current communication mode according to the first connection request and the second connection request specifically includes: judging whether a first connection request and a second connection request are received in the current period; if a first connection request and a second connection request are received in the current period, acquiring a first network signal intensity corresponding to the first connection request and a second network signal intensity corresponding to the second connection request; if the difference value between the first network signal intensity and the second network signal intensity is larger than a preset threshold value, taking the communication mode with the larger network signal intensity as the current communication mode; if the difference value between the first network signal strength and the second network signal strength is smaller than a preset threshold value, acquiring first response time corresponding to the first connection request and second response time corresponding to the second connection request, and taking the communication mode with the earlier response time as the current communication mode; the first response time is the time when the judging module receives the first connection request, and the second response time is the time when the judging module receives the second connection request; and if only the first connection request or the second connection request is received in the current period, taking the communication mode of the currently received connection request as the current communication mode. If the determining module 105 does not receive the connection request within the period, the GSM converting module and the LoRaWAN converting module release the self-blocking state, and start to send the connection request signal to the determining module 105, where it should be noted that the self-blocking state refers to prohibiting sending the connection request to the determining module 105 within 30 seconds.
For example, the determining module 105 obtains a first network signal strength corresponding to the first connection request and a second network signal strength corresponding to the second connection request when receiving the first connection request and the second connection request simultaneously within a period (0.5 second); assuming that the difference between the first network signal strength and the second network signal strength is greater than the preset threshold and the first network signal strength is greater, the GSM mode corresponding to the first network signal strength is used as the current mode, when the determining module 105 determines that the current mode is the GSM mode, the determining module 105 sends a connection permission signal to the GSM conversion module 103, and the determining module 105 sends a connection rejection signal to the LoRaWAN conversion module 104.
Assuming that the difference between the first network signal strength and the second network signal strength is smaller than the preset threshold, the time when the first connection request reaches the determining module 105 and the time when the second connection request reaches the determining module 105 are obtained, and assuming that the time when the second connection request reaches the determining module 105 is earlier than the time when the first connection request reaches the determining module 105, the LoRaWAN corresponding to the second determining module 105 is used as the current communication mode. When determining that the current communication mode is the LoRaWAN mode, the determining module 105 sends a connection permission signal to the LoRaWAN converting module 104, and the determining module 105 sends a connection rejection signal to the GSM converting module 103.
In this embodiment, the determining module 105 is further configured to determine whether the GSM signal processing module 101 or the LoRaWAN signal processing module 102 is currently in communication with the cloud server, and if the GSM signal processing module 101 or the LoRaWAN signal processing module 102 is currently in communication with the cloud server, the determining module 105 rejects receiving the first connection request and the second connection request.
In this embodiment, the determining module 105 determines the connection request signal sent by the GSM converting module and the LoRaWAN converting module, so as to determine the current mode, and effectively improve the transmission efficiency of information.
In this embodiment, if the current GSM signal processing module 101 or the LoRaWAN signal processing module 102 is disconnected from the cloud server, the signal processing module sends a disconnection notification signal to the conversion module, so that the conversion module sends a connection request to the determination module. For example, the GSM signal processing module 101 sends a disconnection notification signal to the GSM conversion module 103, and after receiving the disconnection notification signal, the GSM conversion module 103 sends a first connection request to the determination module 105 after 30 seconds. It should be noted that disconnecting the communication includes ending the communication or responding to a timeout or other abnormal reasons to cause the communication to end.
Therefore, the communication device for the logistics intelligent door lock provided by the embodiment of the invention comprises: the device comprises a GSM signal processing module, a LoRaWAN signal processing module, a GSM conversion module, a LoRaWAN conversion module and a judgment module; the GSM signal processing module is used for sending the GSM signal to the GSM conversion module; the LoRaWAN signal processing module is used for sending the LoRaWAN signals to the LoRaWAN conversion module; the GSM conversion module is used for sending a first connection request to the judgment module after receiving the GSM signal; the LoRaWAN conversion module is used for sending a second connection request to the judgment module after receiving the LoRaWAN signal; and the judging module is used for receiving and determining the current communication mode according to the first connection request and the second connection request.
