All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
According to an embodiment of the present invention, an event notification method embodiment is provided, it being noted that the steps shown in the flowchart of the figures may be performed in a computer system such as a set of computer executable instructions, and, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order other than that shown or described herein.
In this embodiment, an event notification method is provided, which may be applied to a local area network, where the local area network includes at least one intelligent gateway, and fig. 1 is a flowchart of the event notification method according to an embodiment of the present invention, and as shown in fig. 1, the flowchart includes the following steps:
step S101, intelligent gateway change information is obtained. Specifically, when the intelligent gateway itself or its sub-device state attribute changes, a sub-device is newly added, a sub-device is deleted, for example: the intelligent gateway itself changes its network state, a certain switch is turned on or turned off, and a sensor is changed, so that a change message is generated, where the change message may include the changed attribute and state, the changed timestamp, and the change attribution message. Taking the schematic diagram of communication between the intelligent gateway and the multiple receiving ends in the local area network in fig. 4 as an example, the local area network includes a first intelligent gateway, a second intelligent gateway and a third intelligent gateway, and when the network state of the first intelligent gateway changes, the network state change information of the first intelligent gateway is generated; when the second intelligent gateway is added with a sensor device, timestamp information when the second intelligent gateway is added with the sensor device and attribution information when the second intelligent gateway is added with the sensor device are generated; when the third intelligent gateway deletes one piece of sub-equipment, timestamp information when the third intelligent gateway deletes the sub-equipment and attribution information when the third intelligent gateway deletes the sub-equipment are generated.
Step S102, generating a change information event data message based on the intelligent gateway change information. Specifically, when the intelligent gateway changes, an event data message is generated based on the intelligent gateway change information, as shown in fig. 4, when the network state of the first intelligent gateway changes, first intelligent gateway network state change information is generated, and the first intelligent gateway network state change event data message is generated based on the first intelligent gateway network state change information; when a sensor device is newly added to the second intelligent gateway, timestamp information when the sensor device is newly added to the second intelligent gateway and attribution information when the sensor device is newly added to the second intelligent gateway are generated, and a timestamp and attribution information event data message when the sensor device is newly added to the second intelligent gateway are generated based on the timestamp information when the sensor device is newly added to the second intelligent gateway and attribution information when the sensor device is newly added to the second intelligent gateway; when the third intelligent gateway deletes one piece of sub-equipment, timestamp information when the third intelligent gateway deletes the sub-equipment and attribution information when the third intelligent gateway deletes the sub-equipment are generated, and a timestamp and attribution information event data message when the third intelligent gateway deletes the sub-equipment are generated based on the timestamp information when the third intelligent gateway deletes the sub-equipment and attribution information when the third intelligent gateway deletes the sub-equipment.
Step S103, generating an event data packet of the event data message based on the preconfigured intelligent gateway event parameters. Specifically, as shown in fig. 4, the local area network further includes a preset receiving end, where the preset receiving end includes a first receiving end, a second receiving end, a third receiving end, a fourth receiving end, a first encryption module and a second encryption module. The first encryption module is connected with the second intelligent gateway; the second encryption module is connected with the third intelligent gateway.
The pre-configured intelligent gateway event parameters may be: the method comprises the steps of sending an unencrypted event to a first receiving end, a second receiving end and a third receiving end, sending an encrypted event to the second receiving end and the fourth receiving end, and sending contents such as specific message content identification messages to the fourth receiving end. For example: and generating event data packets which are not encrypted by the first receiving end, the second receiving end and the third receiving end based on the change information event data messages of the intelligent gateway for the first receiving end, the second receiving end and the third receiving end to send the event parameters of the intelligent gateway which are not encrypted. And encrypting the change information event data message of the intelligent gateway by the first encryption module based on the event parameters of the intelligent gateway for transmitting the encryption event to the third receiving end, and generating an event data packet encrypted by the third receiving end. And generating event data packets of the second receiving end and the fourth receiving end for sending encryption events and sending specific message content identification messages for the fourth receiving end after the change information event data messages of the intelligent gateway are encrypted by the second encryption module based on the event parameters of the intelligent gateway for sending the encryption events for the second receiving end and the fourth receiving end and sending specific message content identification messages for the fourth receiving end.
Step S104, the event data packet is sent to a preset receiving end by adopting UDP protocol. Specifically, as shown in fig. 4, the local area network further includes a first sending module, a second sending module, and a third sending module; the first sending module is respectively connected with the first intelligent gateway, the first receiving end, the second receiving end and the third receiving end; the second sending module is respectively connected with the first encryption module and the third receiving end; the third sending module is respectively connected with the second receiving end, the fourth receiving end and the second encryption module. The UDP protocol is a short for User Datagram Protocol, known as the user datagram protocol, a connectionless transport layer protocol in the OSI (Open System Interconnection, open systems interconnection) reference model.
When the first sending module receives event data packets which are not encrypted by the first receiving end, the second receiving end and the third receiving end, the event data packets which are not encrypted by the first receiving end, the second receiving end and the third receiving end are respectively sent to the first receiving end, the second receiving end and the third receiving end by adopting a UDP protocol. And when the second sending module receives the event data packet encrypted by the third receiving end of the first encryption module, the event data packet is sent to the third receiving end. When the third sending module receives the second receiving end and the fourth receiving end of the second encryption module, the third sending module sends encryption events and event data packets of specific message content identification messages for the fourth receiving end, the event data packets are respectively sent to the second receiving end and the fourth receiving end.
For example: when the electric quantity value of the electric meter equipment subordinate to the intelligent gateway of the equipment manufacturer is increased, when the intelligent gateway receives the state change reported by the electric meter equipment, an event data message of a corresponding sub-equipment state (new electric quantity value) is generated, and then the event data message is sent to the communication address and the communication port of the configured event receiving end (local area network server main body) of the intelligent gateway according to the system integrator, so that all the configured receiving ends (system integrator service points) can synchronously display the new electric quantity data as pages, record histories, calculate electric quantity consumption in time and other subsequent applications.
According to the event notification method provided by the embodiment of the invention, the change information of the intelligent gateway is obtained, the change information event data message is generated based on the change information of the intelligent gateway, the event data packet of the event data message is generated based on the pre-configured event parameters of the intelligent gateway, finally, the event data packet is transmitted to the preset receiving end by adopting the UDP protocol, when the states of the intelligent gateway and subordinate sub-equipment change, the event data packet is finally generated based on the change information of the intelligent gateway and transmitted to the preset receiving end by adopting the UDP protocol, the event data packet can be timely and accurately transmitted to the appointed receiving end and the communication port, and the problem that the state change of the intelligent gateway and the subordinate sub-equipment cannot be timely and accurately transmitted to the appointed receiving end and the communication port is solved.
In this embodiment, an event notification method is provided, which may be applied to a local area network, where the local area network includes at least one intelligent gateway, and fig. 2 is a flowchart of the event notification method according to an embodiment of the present invention, and as shown in fig. 2, the flowchart includes the following steps:
step S200, generating intelligent gateway event parameters; the intelligent gateway event parameters include: the receiving end communication address, the communication port, the message content identification and the encryption parameter. Specifically, generating the event parameters of the intelligent gateway refers to pre-configuring event parameters to set different requirements of each receiving end in the event notification service of the intelligent gateway. The event parameter configuration comprises the following steps:
receiving end communication address and communication port: the communication address of the receiving end, that is, the IP address of the receiving end, and the communication address and the communication port of the receiving end are used for specifying the IP address and the communication port to be sent to the target receiving end in the UDP protocol transmission, which are necessary parameters for UDP protocol communication.
The message content identifiers are divided into BL and JL, and the message content identifiers are used for specifying the data types of the data message text. BL represents that plaintext after decryption of the packet data content is binary character stream, JL represents that plaintext after decryption of the packet data content is JSON (JavaScript Object Notation, a lightweight data exchange format) format character string, BL is suitable for a receiving end of a small-sized real-time operating system, basically belongs to C language writing receiving application, JL is suitable for a receiving end of a medium-sized and large-sized operating system, can write receiving application by using multiple high-level languages or scripting languages, and can be determined by event parameter configuration.
Encryption parameters include whether to encrypt, type of encryption, encryption key, etc., for use by clients in local area network or intranet communication that require security, due to the event notification service, and the requirement for timeliness, symmetric encryption algorithms are used, with faster encryption speeds, such as DES (Data Encryption Standard, data encryption standard, a block algorithm that uses key encryption), AES (Advanced Encryption Standard ), etc.
The event parameter configuration is stored in the intelligent gateway, and each receiving end has its own corresponding configuration, and when the event notification service is started, the event parameters of each receiving end need to be configured or modified by the security mode interface and stored.
Step S201, intelligent gateway change information is acquired. The intelligent gateway change information includes: the intelligent gateway itself state attribute changes, the sub-device state attribute changes, the time stamp of the sub-device when it is newly added, the attribution information of the sub-device when it is newly added, the time stamp of the sub-device when it is deleted and the attribution information of the sub-device when it is deleted. Please refer to step S101 in the embodiment shown in fig. 1 in detail, which is not described herein.
Step S202, generating a change information event data message based on the intelligent gateway change information. Please refer to step S102 in the embodiment shown in fig. 1 in detail, which is not described herein.
Step S203, generating an event data packet of the event data packet based on the preconfigured intelligent gateway event parameters.
Specifically, the step S203 includes:
generating an event data packet with a preset data format based on a message content identifier and an encryption parameter in the event parameters of the intelligent gateway, wherein the event data packet comprises: message content identification, message function flag, message type, packet body length and packet data content.
The content of the preset data format is as follows: contains a message content identifier (2 bytes), a message function identifier (2 bytes), a message type (2 bytes), a packet body length (4 bytes), and a packet data content (the number of data bytes is determined by the packet body length).
The message content identifier comprises BL and JL, wherein BL represents that plaintext after decryption of the packet data content is binary character stream, JL represents that plaintext after decryption of the packet data content is JSON format character string, BL is suitable for a receiving end of a small-sized real-time operating system, basically belongs to C language writing receiving application, JL is suitable for a receiving end of a medium-sized and large-sized operating system, can write receiving application by using multiple high-level languages or scripting languages, and can be determined by event parameter configuration.
The message function flag indicates whether the data message has an extended function, e.g., whether it is encrypted, bit0 is 1 indicating encryption, and 0 is unencrypted. Other bits may be available for subsequent extended functions.
The event message type is a fixed value, and the rule 9 represents an event notification message and the rule 3 represents a heartbeat message.
The length of the package text is used for determining the receiving quantity of the data text and judging whether the data package text is correct and complete.
The packet data content includes event data for a single device state change, and if encrypted in the event parameter configuration, decryption operations are required.
Step S204, the event data packet is sent to the preset receiving end by adopting UDP protocol. Please refer to step S104 in the embodiment shown in fig. 1 in detail, which is not described herein.
According to the event notification method provided by the embodiment of the invention, the event data packet is easy to send according to the requirement of the receiving end by generating the event parameters of the intelligent gateway and designating the communication address, the communication port, the message content identifier and the encryption parameters of the receiving end, the requirement of the receiving end user with the requirement on safety is ensured by integrating the encryption parameters, and the user population is expanded. Based on the message content identification and encryption parameters in the event parameters of the intelligent gateway, an event data packet with a preset data format is generated, and a receiving end determines and identifies whether the event data packet is an event notification data packet according to the data format of the event data packet, so that a basis is provided for accurately sending the event data packet to a designated IP address receiving end and a communication port.
In this embodiment, an event notification method is provided, which may be used in the above mobile terminal, such as a mobile phone, a tablet computer, etc., and fig. 3 is a flowchart of the event notification method according to an embodiment of the present invention, as shown in fig. 3, where the flowchart includes the following steps:
step S301, obtaining intelligent gateway variation information. Please refer to step S101 in the embodiment shown in fig. 1 in detail, which is not described herein.
Step S302, a change information event data message is generated based on the intelligent gateway change information. Please refer to step S202 in the embodiment shown in fig. 2, which is not described herein.
Step S303, generating an event data packet of the event data message based on the preconfigured intelligent gateway event parameters. Please refer to step S203 in the embodiment shown in fig. 2 in detail, which is not described herein.
Step S304, a heartbeat mechanism is set for the event data packet.
Specifically, step S304 includes:
step S3041, obtaining a preset receiving end communication address and communication port in the event data packet. Specifically, since the UDP protocol has no connectivity, in order to reduce the occupation of invalid resources, a heartbeat mechanism is required to ensure the validity of communication when the UDP protocol is used for communication. The preset receiving end communication address and communication port need to be obtained from the event data packet. For example: the event data packet is an event data packet encrypted by the third receiving end, and the communication address of the third receiving end and the communication interface of the third receiving end are to be obtained from the event data packet.
Step S3042, generating a heartbeat packet based on the communication address and the communication port of the receiving end. Specifically, after the communication address and the communication port of the receiving end are obtained from the event data packet, the heartbeat packet is generated from the communication address and the communication port of the receiving end according to the data packet format of the heartbeat mechanism. For example: and when the event data packet is an event data packet encrypted by the third receiving end, after the communication address of the third receiving end and the communication port of the third receiving end are obtained, generating a heartbeat packet of the communication address of the third receiving end and the communication port of the third receiving end according to a data packet format of a heartbeat mechanism.
Step S3043, setting a heartbeat timeout time for the heartbeat packet, and generating a primary heartbeat message with a heartbeat keep-alive function. Specifically, the heartbeat mechanism needs a heartbeat timeout time parameter to generate a heartbeat message, and the type of the heartbeat message is 3. The heartbeat message of the heartbeat mechanism is only used as a keep-alive mechanism, so that the data text is not encrypted, and only contains two information of the communication address and the communication port of the receiving end, so that the receiving monitoring of the corresponding receiving end of the heartbeat message is proved to exist, and the event data packet is not invalid to be sent.
In step S305, the event data packet is sent to the preset receiving end by using UDP protocol. Specifically, in the time-out of the heartbeat, when the intelligent gateway generates a change event, the UDP protocol is adopted to send the event data packet with the heartbeat message to the receiving end pointed by the current heartbeat keep-alive, so that the event data packet can be ensured to be accurately sent after the current heartbeat keep-alive. When the heartbeat timeout time is exceeded and no new heartbeat message exists in the heartbeat timeout time, the intelligent gateway releases the event message and the event data packet related to the change information, and no event data packet is sent to the receiving end without heartbeat keep-alive, so that the effectiveness of UDP protocol communication and automatic release of communication resources are realized.
For example: as shown in fig. 4, when the event data packet is an event data packet that is not encrypted by the first receiving end, the second receiving end, and the third receiving end, a heartbeat keep-alive is provided for the first receiving end, the second receiving end, and the third receiving end through a heartbeat message, a heartbeat timeout time is set to be 100ms, and within 100ms, the event data packet that is not encrypted by the first receiving end, the second receiving end, and the third receiving end is sent to the first receiving end, the second receiving end, and the third receiving end respectively by adopting a UDP protocol, and if the event data packet exceeds 100ms, no new heartbeat message is provided, the intelligent gateway will release the event message related to the change information and the related event data packet.
The event notification method provided by the embodiment of the invention sets the heartbeat mechanism for the event data packet, so that the event data packet has the primary heartbeat message with a certain keep-alive heartbeat function, and the effects of the effectiveness of communication between the intelligent gateway and the receiving end and the automatic release of communication resources are realized.
