The terms "first," "second," "third," "fourth" and the like in the description and in the claims and in the above drawings, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments described herein may be implemented in other sequences than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus.
For ease of understanding, a specific flow of an embodiment of the present invention is described below with reference to fig. 1, where an embodiment of a telemetry message processing method according to an embodiment of the present invention includes:
101. and obtaining a telemetry message reported by the target Internet of things terminal equipment, wherein the telemetry message comprises an original message body and a product model identifier.
Specifically, the target internet of things terminal device uploads the telemetry message to a target internet of things platform, which may be a third party internet of things platform (e.g., telecommunications or mobile, etc.); the target Internet of things platform forwards a telemetry message reporting request to a server according to an MQTT (Message Queuing Telemetry Transport, message queue telemetry transmission) protocol, and when the server receives the telemetry message reporting request, the server performs data analysis processing on the telemetry message reporting request to obtain an analysis result; and the server performs parameter name and parameter value verification processing on the analysis result to obtain a verification result, and reads a telemetry message reported by the target internet of things terminal equipment from the analysis result when the verification result is that the verification is successful, wherein the telemetry message comprises an original message body and a product model identifier, the original message body is used for indicating a product data packet corresponding to any one of the internet of things terminal equipment connected with the target internet of things platform, and the target internet of things terminal equipment and the product model identifier have a one-to-one correspondence.
It should be noted that, the target internet of things platform has a corresponding platform identifier, and the target internet of things platform is pre-bound with at least one internet of things terminal device (including the target internet of things terminal device), for accessing the same type of internet of things terminal device under the target internet of things platform, the server can define the target internet of things terminal device as a product model under the target internet of things platform, so as to implement configuration of at least one product model for the target internet of things platform, define product attributes, product commands and the like for each product model, and promote device compatibility of a preset lock control system. For example, the target alliance platform is a UTNB platform, and the multiple product models corresponding to the UTNB platform include NB padlock, smart well lid (triaxial detection), smart panel lock, lock controller, and the like, and each product model may include multiple product commands and multiple product attributes (e.g., attributes such as shear lock alarm, ambient temperature, signal strength, chip temperature, gas concentration, lock status, and battery voltage), each product command has a corresponding command identifier, command code, command name, and command parameter, and each product attribute has a corresponding attribute identifier, attribute code, and attribute name. Further, the server performs addition, deletion and modification check processing on the target internet of things platform and a product model under the target internet of things platform through preset internet of things platform management.
It will be appreciated that the execution subject of the present invention may be a telemetry message processing apparatus, a terminal or a server, and is not limited herein. The embodiment of the invention is described by taking a server as an execution main body as an example.
102. And acquiring the equipment type identifier corresponding to the product model identifier, and determining the telemetry attribute mapping relation according to the product model identifier and the equipment type identifier.
The product model identification and the equipment type identification have a one-to-one mapping relation. The product model identifier corresponds to a product model, the device type identifier corresponds to a device type, the product model corresponds to a device type, and the device type identifier are stored in a device type-product model mapping table (i.e., a preset device type mapping table), one device type has a plurality of telemetry attributes (e.g., attribute codes, attribute names, value types, maximum values, minimum values, default values, etc.), a plurality of available resources, a plurality of command lists, a plurality of running states, an associated internet of things platform, etc., and the product attributes of each product model in the associated internet of things platform (including the target internet of things platform) can be mapped to the telemetry attributes of the corresponding device type, so that a telemetry attribute mapping relationship is obtained and stored in the telemetry attribute-product attribute mapping table (i.e., the preset telemetry attribute mapping table). The plurality of device types may include a power device, a common lock control device, and an internet of things device, and may also include other types of devices, which are not limited in this specific application, where the power device and the common lock control device generally have two telemetry properties of a fixed lock state and a door state, so that no consideration is required to be given to association between the telemetry properties and product properties. Specifically, the server sets the product model identifier as a target key, queries the device type-product model mapping table according to the target key to obtain a device type identifier corresponding to the product model identifier, takes the product model identifier and the device type identifier as indexes, and reads the telemetry attribute mapping relation from the telemetry attribute-product attribute mapping table.
It should be noted that, the device compatibility problem is that the product attribute names in the telemetry messages reported by various internet of things terminal devices are different, so that the device compatibility problem cannot be quickly compatible with the devices of various manufacturers. For example: the state attribute is the same as the state attribute, the name of the state is defined in the class A Internet of things terminal equipment, and the name of the state is defined in the class B Internet of things terminal equipment; and the temperature attribute is defined as temp in the class A Internet of things terminal equipment, and is defined as temperature in the class B Internet of things terminal equipment, and the server can be connected into various types of Internet of things terminal equipment according to the conversion of the product model identifier and the equipment model identifier, so that the compatibility of the system is improved.
103. And converting the original message body into a target message body according to the telemetry attribute mapping relation.
The target message body is used for indicating a device data packet identified by a preset lock control system. The preset lock control system corresponds to a plurality of target Internet of things terminal devices. The original message body comprises a plurality of product attribute names and product attribute values corresponding to the product attribute names, the target message body comprises a plurality of telemetry attribute names, and the telemetry attribute mapping relation is used for indicating the telemetry attribute names corresponding to the product attribute names. Specifically, the server correspondingly replaces a plurality of product attribute names in the original message body with a plurality of telemetry attribute names and telemetry attribute values corresponding to the telemetry attribute names according to the telemetry attribute mapping relation to obtain the target message body. The data formats corresponding to the original message body and the target message body respectively can be JSON format of JS object numbered musical notation or YAML format of data serialization, and are not limited herein. For example, when the server receives a telemetry message reported by an Internet of things terminal device named an intelligent panel lock, the server obtains an original message body from the telemetry message as { "state2":0, "security": 75.6, "lockState":1, "batteryVoltage":3.78, "state":1, "signalPower":80.46, "chipTemperature":24.6}, wherein state2 is state, security is ambient humidity, lockState is lock state, batteryVoltage is battery voltage, state is state, signalPower is a power signal, chipTemperature is a chip temperature. The server converts the original message body into a target message body { "status":0, "sensitivity": 75.6, "lockState":1, "batteryVoltage":3.78, "state":1, "signalPower":80.46, "chiptube property": 24.6}, i.e., the server replaces the product attribute name state2 with the telemetry attribute name status.
Further, if the numerical type telemetry attribute has a calculation coefficient, the server also needs to update the telemetry attribute value corresponding to the telemetry attribute name according to the calculation coefficient, and then the replaced message body attribute value also changes. For example, the telemetry attribute is 0.86 for a calculation coefficient corresponding to a batteryVoltage of 0.238 for a calculation coefficient corresponding to a target message body of { "status":0, "humidty": 0.86, "lockState":1, "batteryVoltage":0.238, "state":1, "signalPower":80.46, "chiptube": 24.6}.
104. And acquiring a message rule according to the equipment type identifier, and performing message processing operation on a target message body according to the message rule through a preset message engine.
The number of the message rules may be 1 or a plurality of the message rules, and the method is not limited herein. The message rules include rule names, message content, pre-alarm types, verification logic, and message terminals. The server is different for different types of logistics terminal devices, so that the definition of the message rule is different, for example, the server needs to push the message A when the lockset device is unlocked and locked, and needs to send the message B when the sensor value reaches the defined value. Therefore, the server realizes message flow with configurable message rules based on a preset message rule model, meets various scene requirements, sets corresponding message rules for different types of logistics terminal equipment, and improves suitability of different types of logistics terminal equipment and diversity of corresponding message rules.
Specifically, the server sends a message rule query request to a preset interface service through a preset message engine according to the equipment type identifier to obtain a message rule; the server performs condition screening and information conversion on a plurality of telemetry attribute values in the target message body according to the message rule through a preset message engine to obtain a message to be processed, and performs pushing processing on the message to be processed according to the message rule. For example, the attribute value c in the telemetry message reported by the target internet of things terminal equipment a or the system time satisfies the verification logic set in the message rule, the server converts the target message body into the message to be processed according to the message content, and sends the message to be processed to the message terminal according to the delay triggering rule and the early warning type (for example, delay sending duration or delay sending time) defined in the message rule.
In the embodiment of the invention, the telemetering attribute mapping relation is determined according to the product model identifier and the equipment type identifier by the message engine, the original message body reported by the target internet of things terminal equipment is converted into the target message body according to the telemetering attribute mapping relation, and the message processing operation is carried out on the target message body according to the message rule, so that loose coupling of message conversion processing and suitability of the target internet of things terminal equipment are realized, the telemetering message processing compatibility and flexibility of message processing operation are improved, and the operation safety of the target internet of things terminal equipment is improved.
Referring to fig. 2, another embodiment of a telemetry message processing method according to an embodiment of the present invention includes:
201. and obtaining a telemetry message reported by the target Internet of things terminal equipment, wherein the telemetry message comprises an original message body and a product model identifier.
The specific implementation of step 201 is similar to that of step 101, and detailed description thereof will not be repeated here.
202. And acquiring the equipment type identifier corresponding to the product model identifier, and determining the telemetry attribute mapping relation according to the product model identifier and the equipment type identifier.
The server reads the corresponding equipment type identifier from a preset equipment type mapping table according to the product model identifier, that is, the server generates a first query statement according to the product model identifier, the preset equipment type mapping table and the structured query language grammar rule, the server executes the first query statement to obtain a first query result, when the first query result is not null and accords with the preset equipment type definition rule, the server determines that the first query result is the equipment type identifier, the equipment type identifier can be a numerical value, can be a global unique identifier or can be other types of character strings, and is not limited in particular; then, the server inquires a preset telemetry attribute mapping table according to the equipment type identifier and the product model identifier to obtain a telemetry attribute mapping relation, namely, the server generates a second inquiry statement according to the product model identifier, the preset telemetry attribute mapping table and the structured inquiry language grammar rule, the server executes the second inquiry statement to obtain a second inquiry result, and when the second inquiry result is not null, the server determines that the second inquiry result is the telemetry attribute mapping relation. It can be understood that the preset device type mapping table and the preset telemetry attribute mapping table are provided by the basic data service, the telemetry message is received, and the server inquires the telemetry attribute mapping relation from the basic data service according to the product model identifier, so that the basic data service inquires the preset device type mapping table according to the product model identifier to obtain the device type identifier, and then inquires the preset telemetry attribute mapping table according to the device type identifier to obtain and return the telemetry attribute mapping relation.
It should be noted that, the telemetry attribute mapping relationship may be configured according to actual service requirements. Taking an example of an intelligent panel lock (UT-9341E) as a device type, when a preset lock control system needs to be connected to an Internet of things terminal device of which a product model is the intelligent panel lock (UT-9341E), a server adds a product model intelligent panel lock (UT-9341E) under a target Internet of things platform UNTB, and adds product attributes to the intelligent panel lock (UT-9341E). Correspondingly, the server adds an intelligent panel lock (UT-9341E) for one equipment type according to the same name, configures a plurality of telemetry attributes for the one equipment type, and stores the telemetry attributes in an equipment telemetry attribute table, so that the same name is more visual, and the testing is facilitated. And performing association configuration on the telemetry attributes and the product attributes under the product model through an association Internet of things platform to obtain telemetry attribute mapping relations, and storing the telemetry attribute mapping relations in a preset telemetry attribute mapping table.
203. And converting the original message body into a target message body according to the telemetry attribute mapping relation.
The original message body may be a JSON string, and in some possible embodiments, the server performs deserialization processing on the original message body to obtain a processed message body object, where the processed message body object may be a JSON object; the server performs replacement processing on each product attribute name corresponding to the processed message body object according to the telemetry attribute mapping relation to obtain a replaced message body object, namely, the server performs character string matching on each product attribute name corresponding to the processed message body object and the telemetry attribute names mapped in an associated manner, and replaces the product attribute names with different matching with corresponding telemetry attribute names, for example, the server replaces a product attribute name state2 in the original message body with a telemetry attribute name state, and other attribute names are in one-to-one correspondence with each product attribute name; the server updates the telemetry attribute value corresponding to the replaced message body object according to the preset calculation coefficient to obtain a target message body, and stores the target message body into a preset message queue, wherein the target message body is used for indicating a device data packet identified by a preset lock control system.
204. And reading a message rule from a preset rule configuration table according to the equipment type identifier, wherein the message rule comprises formatted message content, verification logic, a message pushing mode, delay transmission time length, retransmission times and retransmission intervals.
The message rule includes formatted message content, verification logic, message pushing mode and delay sending time length, retransmission times and retransmission interval, and also includes rule name, rule type, retransmission flag, whether application program APP pushes, whether short message notification, whether reset is possible, whether early warning and early warning type are disabled, and the specific method is not limited herein. Specifically, the server takes the device type identifier as an index value, and reads the message rule from a preset rule configuration table according to the index value. The number of rules corresponding to the message rule is a positive integer.
205. And judging whether the target message body accords with the verification logic or not through a preset message engine.
The verification logic comprises judgment logic and at least one judgment item, each judgment item comprises an equipment attribute name, a judgment value type and a judgment condition, and the judgment logic is used for indicating the judgment logic of all the judgment items, and the judgment logic comprises AND, OR, NOT operation and the like. Specifically, the server extracts the equipment attribute value corresponding to each judgment item from the target message body according to the equipment attribute name corresponding to each judgment item; the server checks whether the equipment attribute value corresponding to each judgment item accords with the judgment value type corresponding to each judgment item and the judgment value corresponding to each judgment item according to the judgment condition corresponding to each judgment item; if the device attribute value corresponding to each judgment item accords with the judgment value type and the judgment value, the server determines that the target message body accords with the verification logic, and the server executes step 206.
It should be noted that, when the lock control device shifts, and a certain state value changes/exceeds a limit, the server may need to determine (hereinafter referred to as a message rule) whether the message needs to be triggered according to a certain logic rule. Taking a message rule of "abnormal open" with a device type of "intelligent panel lock (UT-9341E)" as an example, the server extracts judgment logic from the message rule as and operation, and two judgment items, wherein the first judgment item comprises a device attribute name of state (status), a judgment value of 1, a judgment value type of int and a judgment condition of equal, and the second judgment item comprises a device attribute name of state (localState), a judgment value of 0, a judgment value type of int and a judgment condition of equal. If the target message body is { "status":0, "sensitivity": 65.016, "lockState":0, "batteryVoltage":0.89964"state":1, "signalPower":80.46, "chiptube": 24.6}, then the server determines that the target message body complies with the verification logic, i.e., the telemetry message reported by the target logistics terminal apparatus simultaneously satisfies status=1 (door open) and localstate=0 (lock closed).
206. If the target message body accords with the verification logic, generating a message to be processed according to the formatted message content and the target message body, wherein the message to be processed is an early warning type message, a notification type message or a command type message.
Specifically, if the target message body accords with the verification logic, the server queries formatted message content according to the preset matching regular expression to obtain a plurality of character strings to be replaced, each character string to be replaced corresponds to one telemetry attribute name to be replaced, extracts a plurality of telemetry attribute values (telemetry attribute values are abbreviated as attribute values) from the target message body according to the telemetry attribute names to be replaced, and sequentially replaces the plurality of character strings to be replaced according to the telemetry attribute values to obtain a message to be processed, wherein the message to be processed is an early warning type message, a notification type message or a command type message. That is, the content of the transmitted message supports formatting the message, each string to be replaced is shaped like $ { attribute name }, and the server replaces "$ { attribute name }" with "attribute value".
For example, if the formatted message content is "power distribution cabinet $ { name } door is abnormally opened", for example, if the name is "priority 1# door", the server replaces the formatted message content "power distribution cabinet $ { name } door is abnormally opened" with the pending message "power distribution cabinet priority 1# door is abnormally opened". Further, if the telemetry attribute name is absent from the target message body, the server replaces the string corresponding to the telemetry attribute name with an empty string.
207. And pushing the message to be processed according to the message pushing mode and the delay sending time length to obtain a pushing result.
The message pushing modes can include an application program notification mode, a short message notification mode and a mail notification mode, and also can include a message queue telemetry transmission pushing mode, and are not limited in specific, so that the diversity of the message pushing modes is improved. In some possible embodiments, the server determines whether the delay sending duration is a preset value, where the preset value may be 0 or null, and the method is not limited herein; if the delay sending duration is a preset value, the server calls a preset real-time message thread pool to push the message to be processed to the message middleware, and pushes the message to be processed to the message terminal through the message middleware according to a message pushing mode to obtain a pushing result, for example, when status=1 (door open) and localstate=0 (lock close), the server pushes a message with content of 'abnormal open' to the message terminal according to a short message notification mode; if the delay sending duration is not a preset value, the server pushes the message to be processed to the message terminal through a preset delay message thread pool according to a message pushing mode to obtain a pushing result, namely if the delay sending duration is not a preset value, the server determines that the message to be processed is a delay message, determines a delay sending moment according to the current moment and the delay sending duration, and pushes the message to be processed to the message terminal through the preset delay message thread pool at the delay sending moment to obtain the pushing result. It should be noted that, the server may process telemetry messages sent by multiple target logistics terminal devices, so that the server manages MQ messages through a preset real-time message thread pool and a preset delay message thread pool to support a large-scale device group, thereby improving data processing efficiency and system performance.
Further, if the delay sending duration is a preset value, the server determines that the message to be processed is a real-time message, and invokes a preset real-time message thread pool to push the message to be processed to message middleware (for example, a message server activemq, a message proxy software rubbitmq, a lightweight message kernel zeromq, a kafka, a remote service dictionary redis and the like), and invokes a corresponding preset service interface through the message middleware according to a message pushing mode to push the real-time message to the message terminal based on the preset service interface, so that a pushing result is obtained, wherein the pushing result comprises success pushing and failure pushing; if the pushing result is the preset target value, the server determines that the pushing result is pushing success, and the server executes step 208; if the pushing result is not the preset target value, the server determines that the pushing result is a pushing failure, and the server executes step 209, where the preset target value may be SUCCESS or 1, or may be logical true, which is not limited herein. The message pushing mode and the message terminal have a corresponding relation.
208. And deleting the message to be processed from a preset message queue when the pushing result is that the pushing is successful.
Specifically, when the pushing result is that pushing is successful, the server acquires the number of messages from a preset message queue, if the number of messages is 1, the server acquires a message identification value corresponding to the message queue, for example, the message identification value is msgid, the server generates a message deleting statement according to the message identification value and a preset instruction, for example, the preset instruction is ipcrm-q, the message deleting statement is msgid, and the server executes the message deleting statement to delete the message to be processed; if the number of the messages is greater than 1, the server matches a preset message queue according to the message to be processed, obtains matched message data, and cleans the matched message data.
209. And when the pushing result is that the pushing is failed, retransmitting the message to be processed according to the retransmission times and the retransmission intervals.
The retransmission times and the retransmission intervals are configured according to the actual service requirements, so that the flexibility of message processing of push failure is improved. In some possible embodiments, when the pushing result is that the pushing fails, the server migrates the message to be processed in the preset message queue to the preset message memory table to be sent; the server retransmits the message to be processed in the message memory table to be transmitted according to the retransmission times and retransmission intervals through a preset message engine to obtain a transmission result; and when the sending result is that the sending is successful, the server clears the message to be processed in the memory table of the preset message to be sent.
Further, the server acquires the message to be processed which is pushed successfully, and updates the message to be processed which is pushed successfully into a message cache table; the server checks whether junk data exists in the message cache table through a preset timing polling thread; if the junk data exists in the message cache table, the server deletes the junk data through a preset data clearing thread, and specifically if the junk data exists in the message cache table, the server sets a clearing mark and clearing description information on the junk data, the server deletes the junk data through the preset data clearing thread according to the clearing mark, clearing information is generated in the process of clearing the data, the clearing information comprises the junk data, clearing time and clearing description information, and the clearing information is recorded in a preset operation log table, so that the target terminal displays a clearing list based on the preset operation log table.
