Fig. 1 is a schematic structural diagram of an information processing system in an embodiment of the present application, and as shown in fig. 1, the information processing system includes: the system comprises a server, at least two gateways and at least two devices; wherein the content of the first and second substances,
a device arranged to deliver a message by broadcast.
A gateway configured to perform deduplication processing on a message from a device; forwarding the message which needs to be reported and is subjected to de-duplication processing to a server according to the filtering rule information which is stored by the server and indicates whether to report the message of the specified equipment; a message from the server is broadcast.
The server is arranged to generate filtering rule information which indicates whether the gateway reports the information from the specified equipment or not, and send the filtering rule information to the gateway for storage; and sending the message to a gateway included in the route reported by the equipment.
In an exemplary example, the gateway may be a gateway having a BLE function, and in the embodiment of the present application, for uplink processing, the gateway has a function of removing duplicate of a message, and simultaneously filters the message after the duplicate removal, so as to implement that the uplink message is changed from multi-path to single-path transmission, and for downlink processing, a broadcast manner is adopted, so that the downlink message is changed from single-path to multi-path; the device may be a mobile device with BLE functionality, such as, for an office scenario, the device may include but is not limited to such as: notebook computers, electronic screens, projection equipment, smart phones, environmental sensors, and the like; the following steps are repeated: for mall scenarios, the devices may include, but are not limited to, such as: shopping carts, yard guns, etc.
In one illustrative example, the deduplication process comprises: the repeated messages from the same equipment are discarded, that is, only one message is reserved when a plurality of received messages from the same equipment are the same, so that the same gateway only reports the same message to the server once, and the system overhead is reduced.
In an exemplary example, the device signal strength may be distinguished according to the device signal strength reported by the gateway, or may be distinguished by signal coverage strength of different areas formed by different radii with the device as a center.
In an exemplary embodiment, the filtering rule information is preset to ensure that a gateway in a strong signal area of a device will report the message of the device to the server. Such as: if the strategy of the filtering rule information is to determine whether the gateway reports the filtering information of the message of the equipment according to the signal intensity of the equipment, only the gateway in a strong signal area of the equipment reports the message of the equipment after the same message is received by a plurality of gateways, thereby ensuring the reliability of the message transmitted to a server; the following steps are repeated: if the strategy of filtering the rule information is to determine whether the gateway reports the message of the device according to the signal coverage strength of the signal coverage area of the device, if the area with the preset radius taking the device as the center of a circle is the strong signal coverage area, then after the same message is received by a plurality of gateways, only the gateway in the strong signal area of the device reports the message of the device, and the reliability of transmitting the message to the server is ensured.
In an exemplary embodiment, the filter rule information in the server, which is used to indicate whether the gateway reports a message from a device, is set as:
and marking the gateway with the equipment signal strength smaller than the preset signal strength threshold value as a gateway which does not report the information of the equipment, marking the gateway with the equipment signal strength not smaller than the preset signal strength threshold value as a gateway which reports the information of the equipment, and generating filtering rule information according to the marking result.
The information processing system provided by the embodiment of the application adopts a broadcast mode to transmit the message, the cost is minimum because the broadcast does not need to establish connection, the binding processing between the equipment and the gateway is not needed, the networking is more flexible, and the cost is reduced.
Such as: one broadcast of BLE requires only 3 milliseconds (ms), but a connection takes almost 3000ms. In addition, in the embodiment of the application, repeated messages from the same equipment are removed through duplicate removal processing in the gateway, so that the same gateway only reports the same message once; by filtering the information, after the same message is received by a plurality of gateways according to a preset strategy, only the gateway in the strong signal area of the equipment can report the message of the equipment, thereby ensuring the reliability of transmitting the message to the server. Therefore, the transmission of the uplink message is well ensured to be changed from multi-path transmission to controllable single-path transmission, the high availability of the information processing system is ensured, and the flow is controllable. As can be seen from the system diagram shown in fig. 1, the same message, device will repeat the transmission n times; and the gateway forwarding these messages will receive multiple (n ≦) duplicate messages.
Through the information processing system in the embodiment of the application, on one hand, for each gateway, repeated messages from the same equipment are removed, the same gateway only reports the same message once, and the expense is reduced; on the other hand, through further processing according to the filtering rule information, only the gateway in the strong signal area of the equipment reports the information of the equipment to the server, and the reliability of transmitting the information to the server is ensured.
Such as: if the strategy of the filtering rule information is to determine whether the gateway reports the filtering information of the message of the equipment according to the signal intensity of the equipment, only the gateway in a strong signal area of the equipment reports the message of the equipment after the same message is received by a plurality of gateways, thereby ensuring the reliability of transmitting the message to a server; the following steps are repeated: if the strategy of filtering the rule information is to determine whether the gateway reports the message of the device according to the signal strength of the signal coverage area of the device, if the area with the preset radius taking the device as the center of a circle is the strong signal coverage area, after the same message is received by a plurality of gateways, only the gateway in the strong signal area of the device reports the message of the device, and the reliability of transmitting the message to the server is ensured.
In one illustrative example, the apparatus is further arranged to: and encrypting the message to be sent and the serial number of the message, and sending the encrypted message in a broadcasting mode. The sequence number (sn) of the message may be a value obtained by incrementing the step number (for example, by 1) after each message is sent.
In an illustrative example, the gateway forwards the message transparently.
In one illustrative example, the server may look up a pre-stored key based on an Identification (ID) of the device and decrypt the received message using the obtained key.
In an exemplary embodiment, when the server is to control a device, the server is further configured to: by searching the route reported by the equipment, the control message to be sent is sent to the gateway in the route; the gateway in the route is set as: broadcasting and sending the received control message to the equipment; the apparatus is further arranged to: performing an action according to a control command obtained from the received control message. In one embodiment, the server may be configured to: by searching for a route (the route may include a plurality of gateways) reported by the device, a control message to be sent, such as a control command, is encrypted and then sent to the gateways in the route; the gateway may then be arranged to: broadcasting and sending the encrypted control command to the equipment; the apparatus may be arranged to: and decrypting the obtained control command according to the key stored in the device, and executing the action after confirming the correctness of the message.
Generally, a device may first assume that a received broadcast message is its own message, decrypt the message using its stored key, and then decode the decrypted key using a Cyclic Redundancy Check (CRC), which indicates that the received message is its own message. Besides, there are Type-Length-Value (TLV, type, length, value) format checks, etc. to ensure message correctness.
In an exemplary embodiment, when the server issues the message to the gateways, N gateways meeting preset conditions (such as light load and good signal) may be selected from the gateways in the route as the gateways that receive the message issued by the server. Through the processing, the transfer of the downlink message is well changed from single path transfer to elastic multi-path transfer, and because the gateway for transferring the message is a gateway with light load and good signal, and is a gateway with light load and good signal in part of the route, the high availability of the information processing system is ensured, and the flow is controllable.
In one illustrative example, the apparatus is further arranged to: after receiving the message from the server, sending an acknowledgement message such as an Acknowledgement Character (ACK) to the gateway; the gateway is further configured to: reporting an acknowledgement message from the device to the server to indicate an acknowledgement reach; the server is further configured to: and if the preset first timer is overtime and still does not receive the ACK from the equipment, retransmitting the message, wherein the gateway for receiving the retransmitted message also comprises a gateway marked as the message not to be reported to the equipment, thereby improving the touch rate. Wherein the first timer may be started simultaneously when the server issues the message.
In an exemplary embodiment, the filtering information in the server for determining whether the gateway reports the message of the device according to the signal strength of the device may be set as:
according to the equipment signal strength reported by the gateways around the equipment, the gateway with the equipment signal strength smaller than the preset signal strength threshold value is marked as the gateway which does not report the information of the equipment, and the gateway with the equipment signal strength not smaller than the preset signal strength threshold value is marked as the gateway which reports the information of the equipment, so as to generate the filtering information. The mode for dividing the signal strength of the device may be dividing according to the signal strength of the device reported by the gateway, or dividing by adopting the signal coverage strength of different areas formed by different radiuses with the device as the center of a circle.
Fig. 2 is a schematic view of a scenario for determining filtering information in an embodiment of the present application, as shown in fig. 2, there is a high-density gateway deployment around a device, and for this situation, a "weak signal limitation reporting" policy is established with a single device as a dimension, that is, as shown in fig. 2, a white circular area is a strong signal area, a gateway in the strong signal area may report a message of the device, a gray circular area is a weak signal area, for example, a gateway in the weak signal area does not report a message of the device, so that the gateway knows whether itself can report a message from the device to a server, for example: the server may, for example, mark a gateway whose signal strength is smaller than a preset signal strength threshold as a gateway that does not report the message of the device, and mark a gateway whose signal strength is not smaller than the preset signal strength threshold as a gateway that reports the message of the device according to a preset period or dynamically according to the device signal strength reported by gateways around the device, so as to generate filtering information, and send the filtering information to a relevant gateway, which may also be referred to as a grey list mechanism. And the following steps: the server may also issue a report restriction policy for the device only to the determined gateways that do not report the message of the device. In short, the specific implementation manner is various, and the present application is not limited as long as the gateway knows whether to report the message from a device according to the filtering information after knowing that the message from the device is received.
It should be noted that the above-mentioned manner of determining whether the gateway reports the message of the device to the server according to the device signal strength is only a specific embodiment, and is not limited to the method for acquiring the filtering information in this application. For example, the gateway in the range of the preset first radius, which takes the device as the center of a circle, is the gateway that reports the message of the device to the server, and the gateway in the annular region formed within the second radius outside the preset first radius is the gateway that does not report the message of the device to the server; wherein the second radius is greater than the first radius. And the following steps: the gateway marked to report the message of a certain device to the server can be further randomly selected or a preset number of gateways are selected according to the strength sequence of the signal intensity of the device to serve as the gateway which finally reports the message of the device to the server. It is emphasized that in the embodiment of the present application, a selection is made for the gateways that receive the same message from the same device, and a gateway with good transmission capability is selected to report the message, so as to ensure the reliability of message delivery to the server.
According to the grey list mechanism provided by the embodiment of the application, after the same message is received by a plurality of gateways, only the gateway which is not set as the grey list reports the received message, that is, after the same message is received by the plurality of gateways, only the gateway which is in the strong signal area of the device reports the message of the device, thereby ensuring the reliability of the message transmitted to the server.
In one illustrative example, the server is further configured to: and updating the filtering rule information regularly, for example, according to a preset period or dynamically according to the equipment signal strength reported by the gateways around the equipment.
When the device position moves, for example, deviates from the circle center position shown in fig. 2, the device signal strength reported by the gateway around the device changes, and in this case, the server may update the tag information of the gateway, that is, the information of whether to report the message of the device, for example, according to a preset period or dynamically. Such as: if the signal intensity of the gateway originally in the gray ring area exceeds the preset signal intensity threshold, the signal intensity can be immediately reported to a server or updated in periodic detection. The updating and filtering information provided by the embodiment of the application realizes self-adaptive processing on the change of the transmission capability of the gateway caused by the change of the position of the equipment, and ensures the reliable access of the message.
According to the grey list mechanism provided by the embodiment of the application, the repeated reporting of the same message by a plurality of gateways is limited, and the same message can be sent to a server through controllable multipath, so that the reliable contact of the message is ensured.
Fig. 3 is a schematic diagram of deduplication processing and filtering processing in an embodiment of the present application, and as shown in fig. 3, an example that a gateway, such as a gateway 1, receives n identical messages from the same device in the upper half of the dash-dot line in this embodiment is that the n identical messages include: message 1_1 (msg 1_ 1), message 1_2 (msg 1_ 2) \8230message1 _n (msg 1_ n), that is, the n same messages are repeatedly sent n times on the device side, and one of the n messages is reserved as message 1 to be reported on the gateway 1 side through the re-processing, so that for the same gateway such as gateway 1, the repeated message 1 from the same device is removed, the same gateway only reports the same message once, and the expense is reduced. In this embodiment, for example, when the detection period comes, the server issues the filtering information to each gateway, and the lower half below the dash-and-dot line in this embodiment uses the gateway 1 and the gateway m as gateways that are not set as a grey list, that is, the gateway 1 and the gateway m are gateways of the network device signal strength, so that the message 1 that is subjected to the past re-processing in the gateway 1 and is ready to be reported is reported to the server.

a deduplication module configured to perform deduplication processing on a message from a device;
the filtering module is set to forward the information after the deduplication processing which needs to be reported to the server according to the filtering rule information which is stored by the filtering module and indicates whether the information of the specified equipment is reported or not;
and the delivery module is arranged for broadcasting the message from the server so as to realize message delivery between the server and the equipment.
In one illustrative example, the filtering rule information includes: the flag corresponding to the device is information of whether to report a gateway of a message of the corresponding device. That is, the filtering rule information includes: the gateway with the equipment signal strength smaller than the preset signal strength threshold value is marked as a gateway which does not report the information of the equipment, and the gateway with the equipment signal strength not smaller than the preset signal strength threshold value is marked as a gateway which reports the information of the equipment. Here, the device signal strength is divided according to the device signal strength reported by the gateway, or divided by the signal coverage strength of different areas formed by different radiuses with the device as the center of a circle. Such as: the gateway with the equipment signal intensity smaller than the preset signal intensity threshold is marked as a gateway which does not report the message of a certain equipment, and the gateway with the equipment signal intensity not smaller than the preset signal intensity threshold is marked as a gateway which reports the message of the certain equipment. The filtering rule information may also be: only information of gateways corresponding to devices marked as messages not reporting the corresponding devices, such as: the gateway with the equipment signal intensity smaller than the preset signal intensity threshold is marked as a gateway which does not report the message of certain equipment; or, only information of a gateway corresponding to the device, which is marked as a message reporting the corresponding device, is included, such as: and the gateway with the signal intensity not less than the preset signal intensity threshold value is marked as a gateway for reporting the message of the equipment.
Through the gateway provided by the embodiment of the application, on one hand, repeated messages from the same equipment are discarded through deduplication processing, that is, only one message is reserved when multiple received same messages from the same equipment, so that for each gateway, the repeated messages from the same equipment are removed, the same gateway only reports the same message once, and the expense is reduced; on the other hand, through further processing of the filtering rule information, after the same message is received by the multiple gateways according to a preset strategy, only the gateway in the strong signal area of the device can report the message of the device, so that the message of the device is ensured to be reported to the server by the gateway in the strong signal area of the device, that is, after the same message is received by the multiple gateways, only the gateway in the strong signal area of the device can report the message of the device, and the reliability of message transmission to the server is ensured.
In an exemplary embodiment, as shown in fig. 4, the gateway receives multiple messages from multiple devices on the device side, for example, n identical messages 1 from device 1, i identical messages 2 \8230fromdevice 2, j identical messages m from device m, and after processing by the deduplication module, 1 message 1 from device 1, 1 message 2 \8230fromdevice 2, and 1 message m from device m remain. Based on the filtered information from the server, such as: assume that the gateway is marked as: the gateway that does not report the message of the device 1, the gateway that does not report the message of the device m, and the gateway that reports the message of the device 2, then the reported message shown in fig. 4 includes 1 message 2. The following steps are repeated: assume that the gateway is marked as: a gateway reporting the message of the device 1, a gateway not reporting the message of the device m, and a gateway reporting the message of the device 2, so that the reported message shown in fig. 4 includes 1 message 1 and 1 message 2.
Fig. 5 is a schematic flowchart of an embodiment of a method for implementing information processing in an embodiment of the present application, as shown in fig. 5,

In one illustrative example, the filtering rule information includes: the flag corresponding to the device is information of whether to report a gateway of a message of the corresponding device. That is, the filtering rule information includes: the gateway with the equipment signal intensity smaller than the preset signal intensity threshold is marked as a gateway which does not report the information of the equipment, and the gateway with the equipment signal intensity not smaller than the preset signal intensity threshold is marked as a gateway which reports the information of the equipment. Here, the device signal strength is divided according to the device signal strength reported by the gateway, or divided by the signal coverage strength of different areas formed by different radiuses with the device as the center of a circle. Such as: the gateway with the equipment signal intensity smaller than the preset signal intensity threshold is marked as a gateway which does not report the message of a certain equipment, and the gateway with the equipment signal intensity not smaller than the preset signal intensity threshold is marked as a gateway which reports the message of the certain equipment. The filtering rule information may also be: only information of gateways corresponding to devices marked as messages not reporting the corresponding devices, such as: the gateway with the equipment signal intensity smaller than the preset signal intensity threshold is marked as a gateway which does not report the message of certain equipment; or, only information of a gateway corresponding to the device, which is marked as a message reporting the corresponding device, is included, such as: the gateway with the signal intensity not less than the preset signal intensity threshold is marked as the gateway reporting the message of a certain device.
Through the step, the gateway in the strong signal area of a certain device can report the message of the device to the server, namely, after the same message is received by a plurality of gateways, only the gateway in the strong signal area of the device can report the message of the device, and the reliability of transmitting the message to the server is ensured.
It should be noted that, the embodiments of the present application may further include:
and according to user preference or use habit and the like, a gateway bound with the equipment is configured in advance. For this case, the method for implementing information processing may further include:
selecting whether to adopt the configured gateway to realize information processing or adopt the method shown in the figure 5 to realize information processing through a preset user interface;
alternatively, on the basis of the method for implementing information processing shown in fig. 5, a configured gateway is preferentially selected to deliver information of a device.
Step 502: and broadcasting the message from the server to realize message transfer between the server and the equipment.
In the embodiment of the application, the information is transmitted between the equipment and the gateway in a broadcast mode, the cost is minimum because the broadcast does not need to establish connection, the binding processing between the equipment and the gateway is not needed, and the cost is reduced.
The present application also provides a computer-readable storage medium storing computer-executable instructions for executing the method of implementing information processing of any one of the above-mentioned fig. 5.
