[0043] Overview

[0044] As described in the background technology, with the continuous development of automobile intelligence, the number and types of vehicle-mounted devices are becoming more and more abundant, and the complexity of the control logic of vehicle-mounted devices is gradually increasing. Therefore, it is particularly important to efficiently, scalably and reliably control the linkage of multiple devices.

[0045] At present, the linkage control of equipment is usually achieved through rule engines, such as Node Rules, which are implemented in JavaScript, and Drools, which are implemented in Java. However, the existing rule engines usually control the equipment in sequence according to pre-set rules, which is difficult to meet the diversified linkage control requirements of vehicle-mounted equipment.

[0046] In order to solve the problem that traditional methods are difficult to meet the diversified linkage control needs of vehicle-mounted equipment through rule engines, in the technical solution of the present application, the equipment linkage control method determines the target control rule from multiple predetermined control rules based on the received vehicle equipment data, and calls the target execution unit in each execution unit corresponding to the target control rule based on the target control rule and the equipment data to perform equipment linkage control on the vehicle, wherein the execution unit is used to process the equipment data and / or execute the action corresponding to the target control rule, thereby, the control rule to be executed can be determined according to the received equipment data, and each control rule can meet the diverse action execution needs by calling the target execution unit during the execution process, thereby meeting the diversified linkage control needs of vehicle-mounted equipment.

[0047] Based on the above-mentioned inventive concept, the device linkage control method provided in the implementation manner of this specification is exemplarily described below.

[0048] Exemplary Methods

[0049] The embodiment of this specification provides a device linkage control method, such as Figure 1 As shown, including:

[0050] S101 . Determine a target control rule from a plurality of predetermined control rules based on received vehicle equipment data.

[0051] Specifically, the device linkage control method can be applied to the rule execution module of the vehicle. The device data of the vehicle can be the real-time status data and / or real-time operation data of the vehicle-mounted devices in the vehicle during the real-time operation of the vehicle. The device data of the vehicle can be forwarded to the rule execution module through the message server of the vehicle. For example, the message server can obtain the device data of the vehicle in real time by subscription, and send it to the rule execution module through MQTT (Message Queuing Telemetry Transport).

[0052] The predetermined control rule may be pre-set in the rule execution module, or updated in real time according to the received rule file, and may be set according to actual needs. The predetermined control rule may be used to characterize the linkage control rule of the vehicle-mounted device.

[0053] After receiving the device data of the vehicle, a target control rule may be determined from a plurality of predetermined control rules based on the device data. The target control rule may be a predetermined control rule among the plurality of predetermined control rules that needs to use the received device data during execution.

[0054] S102. Based on the target control rule and the device data, the target execution unit in each execution unit corresponding to the target control rule is called to perform device linkage control on the vehicle; the execution unit is used to process the device data and / or execute the action corresponding to the target control rule when called.

[0055] Specifically, the execution unit can be an API (Application Programming Interface), a component, etc. In implementation, in the process of constructing or configuring a predetermined control rule, the execution unit corresponding to the predetermined control rule can also be configured. Among them, the execution units corresponding to different predetermined control rules can be the same or different, that is, different predetermined control rules can call the same execution unit or different execution units during the execution process, which can be set according to actual needs. The execution unit can be used to process the currently received device data and / or execute the action corresponding to the target control rule when called. For example, the execution unit "messageCtx.get()" can be used to parse and process the device data, the execution unit "setVal()" can be used to store the rule judgment result in a predetermined storage module, the execution unit "log.info()" can be used to transmit the status judgment result of the vehicle-mounted device back to the cloud, and the execution unit "publish()" can be used to publish the control instruction to the vehicle's message server.

[0056] For any predetermined control rule, the predetermined control rule may include multiple processing steps, and execution units may be configured for some or all of the processing steps according to requirements to obtain execution units corresponding to the predetermined control rule.

[0057] Among them, an execution unit library can be configured in the rule execution module, and the execution unit library can be used to store various execution units. In implementation, various execution units in the execution unit library can be generated based on the data processing requirements of different control rules and / or the actions to be executed. For example, the data processing requirements may include data parsing and processing, and the actions to be executed may include data storage, instruction issuance, etc., so as to meet the diverse action execution requirements of various predetermined control rules.

[0058] In implementation, the target execution unit in each execution unit corresponding to the target control rule can be called based on the target control rule and the device data to realize the linkage control of the vehicle-mounted device. Among them, the target execution unit can include the execution unit corresponding to each processing step to be executed in the target control rule in the process of executing the target control rule based on the device data.

[0059] Therefore, by calling the target execution unit to perform various actions during the execution of the target control rules, the diversified linkage control requirements of the vehicle-mounted equipment can be effectively met.

[0060] In a feasible implementation manner, determining the target control rule from a plurality of predetermined control rules based on the received vehicle equipment data includes:

[0061] Based on the matching result between the device data and the target device data corresponding to each of the predetermined control rules, the target control rule is determined from the plurality of predetermined control rules.

[0062] Specifically, for any predetermined control rule, the target device data corresponding to the predetermined control rule is the device data required to be used during the execution of the predetermined control rule.

[0063] After receiving the device data of the vehicle, the device data can be matched with the target device data corresponding to each predetermined control rule, and the predetermined control rule corresponding to the successfully matched target device data can be used as the target control rule, so that the target control rule can be quickly and comprehensively determined from multiple predetermined control rules. Thus, different device linkage controls can be realized through a set of device data, so that the diversified linkage control of vehicle-mounted devices can be effectively met.

[0064] In implementation, the target device data can be configured in the attribute information of each predetermined control rule, so that the target control rule can be quickly and accurately determined after receiving the device data of the vehicle. In addition, a processing step for matching the device data can be configured in each predetermined control rule. The processing step for matching the device data can determine whether to continue to execute the predetermined control rule based on the matching result of the identification information corresponding to the device data and the identification information corresponding to the target device data. If so, the predetermined control rule is the target control rule, and if not, the predetermined control rule is not the target control rule. The identification information can include the identification information of the vehicle-mounted device, and can also include the identification information of the parameters of the vehicle-mounted device, etc. For example, after receiving the device data of the vehicle, the device data can be input into the execution thread of each predetermined control rule to determine the target control rule during the execution of each predetermined control rule.

[0065] In a feasible implementation manner, the process of determining the target execution unit includes:

[0066] Based on the target control rule and the device data, determining a current processing step of the target control rule;

[0067] The execution unit corresponding to the current processing step is used as the target execution unit.

[0068] Specifically, the current processing step of the target control rule is the processing step executed at the current moment during the execution of the target control rule.

[0069] In implementation, the current processing step of the target control rule can be determined based on the target control rule and the device data. For example, during the execution of the target control rule, the current processing step can be determined based on the matching result between the device data and the rule parameters in the target control rule.

[0070] After determining the current processing step, the execution unit corresponding to the current processing step can be used as the target execution unit, and the target execution unit can be called to process the device data or execute the action required to perform the current processing step. By calling the target execution unit, the diverse action execution requirements of the target control rules can be effectively met, thereby meeting the diversified linkage control requirements of vehicle-mounted equipment.

[0071] In a feasible implementation manner, the execution unit corresponding to the target control rule includes a result storage unit;

[0072] The calling of the target execution unit in each execution unit corresponding to the target control rule based on the target control rule and the device data includes:

[0073] When the execution unit corresponding to the current processing step is the result storage unit, the result storage unit is called and the rule determination result in the current processing step is input into the result storage unit; the result storage unit is used to store the rule determination result in the current processing step into a predetermined storage module.

[0074] Specifically, the execution unit corresponding to the target control rule may include a result storage unit, and the result storage unit may be used to store the rule determination result in the current processing step into a predetermined storage module during the calling process.

[0075] During implementation, during the execution of the target control rule, if the execution unit corresponding to the current processing step is a result storage unit, the result storage unit can be called from the execution unit library, and the rule judgment result in the current processing step of the target control rule can be input into the result storage unit, so that the rule judgment result in the current processing step can be stored in a predetermined storage module through the result storage unit. The predetermined storage module can be a result manager, so that in the subsequent processing steps of the target control rule and / or the execution of other predetermined control rules, the rule judgment result can be called in real time, thereby further meeting the diversified linkage control needs of vehicle-mounted equipment.

[0076] In a feasible implementation manner, the execution unit corresponding to the target control rule includes an instruction issuing unit;

[0077] The calling of the target execution unit in each execution unit corresponding to the target control rule based on the target control rule and the device data includes:

[0078] When the execution unit corresponding to the current processing step is the instruction issuing unit, the instruction issuing unit is called, and the control instruction determined by the current processing step is input into the instruction issuing unit; the instruction issuing unit is used to publish the control instruction determined by the current processing step to the message server of the vehicle, and the message server is used to forward the control instruction to the vehicle-mounted device corresponding to the control instruction.

[0079] Specifically, the execution unit corresponding to the target control rule may include an instruction publishing unit, which can be used to publish the control instruction determined by the current processing step to the vehicle's message server during the calling process. The vehicle's message server can be used to forward data between the vehicle's onboard device and the rule execution module. For example, the onboard device can interact with the message server through a gateway device, and the forwarded data may include control instructions and device data. For example, the onboard device can obtain the control instruction corresponding to the onboard device from the message server in real time by subscription. When the message server receives the control instruction, it can send the control instruction to the corresponding onboard device by MQTT.

[0080] During implementation, during the execution of the target control rule, if the execution unit corresponding to the current processing step is an instruction issuing unit, the instruction issuing unit can be called from the execution unit library, and the control instruction determined in the current processing step of the target control rule can be input into the instruction issuing unit, so that the control instruction determined in the current processing step can be published to the message server through the instruction issuing unit, so that the control instruction can be forwarded to the vehicle-mounted device corresponding to the control instruction through the message server, thereby effectively improving the vehicle's equipment linkage control efficiency and the reliability of the control results.

[0081] In a feasible implementation manner, after determining the target control rule from a plurality of predetermined control rules based on the received vehicle equipment data, the method further includes:

[0082] A different execution thread is allocated to each of the target control rules, and the execution thread is used to execute the corresponding target control rule.

[0083] Specifically, after determining the target control rule, different execution threads can be assigned to each target control rule. Among them, for any assigned execution thread, the execution thread can be used to execute the corresponding target control rule. In implementation, the received device data can be sent to each assigned execution thread, so that when there are multiple target control rules, multiple target control rules can be executed concurrently without affecting each other, thereby effectively improving the linkage control efficiency of the vehicle-mounted equipment.

[0084] It is understandable that when processing steps for device data matching are configured in the predetermined control rules, an execution thread can be assigned to each predetermined control rule after receiving the device data, so as to quickly identify the target control rule by executing the execution thread corresponding to each predetermined control rule.

[0085] In a feasible implementation manner, the attribute information of each of the predetermined control rules includes an execution order;

[0086] After determining the target control rule from a plurality of predetermined control rules based on the received vehicle equipment data, the method further includes:

[0087] If there are multiple target control rules, and the execution mechanism of the multiple target control rules is sequential execution, then the execution priority of each target control rule is determined based on the execution order corresponding to each target control rule;

[0088] Based on the execution priority of each of the target control rules, each of the target control rules is executed in sequence.

[0089] Specifically, for any predetermined control rule, in the process of configuring the predetermined control rule, the attribute information of the predetermined control rule can also be configured. The attribute information of the predetermined control rule can include the execution order of the predetermined control rule, and the execution order can represent the execution order of the predetermined control rule in the process of sequentially executing multiple predetermined control rules.

[0090] In implementation, after determining the target control rules, if there are multiple target control rules and the execution mechanism of the multiple target control rules is sequential execution, the execution priority of each target control rule can be determined based on the execution order corresponding to each target control rule. For example, the execution priority of each target control rule can be determined based on the change trend of the execution priority with the execution order. For example, if the smaller the value of the execution order is, the higher the execution priority is, the execution order of each target control rule can be sorted, and according to the sorting result, the execution priority of each target control rule can be determined in the order of the execution order value from small to large.

[0091] After obtaining the execution priority of each target control rule, each target control rule can be executed in sequence according to the execution priority from high to low, so that the vehicle's on-board equipment can be flexibly and effectively controlled in linkage, thereby meeting the diversified linkage control needs of the on-board equipment.

[0092] In a feasible implementation manner, the process of constructing the predetermined control rule includes:

[0093] When a rule update request is received, a rule file in the rule update request is obtained; the rule file includes a control rule and execution units corresponding to different processing steps in the control rule;

[0094] Based on the rule file, the predetermined control rule and the execution unit corresponding to the predetermined control rule are updated.

[0095] Specifically, the rule update request can be used to request the rule execution module to update the predetermined control rules. For example, the rule design end can obtain the rule file, and when the rule file is updated, send a rule update request (such as HTTP (Hypertext Transfer Protocol) request) including the rule file to the rule execution module. The rule design end can be the cloud or other devices. In implementation, when there are updates to the vehicle's on-board equipment or the working conditions of the on-board equipment, the user can generate a rule file on the rule design end through a text editor and low-code design tools, and can also input pre-made rule files to the rule design end, and can also input the required data when generating the rule file to the rule design end, so that the rule design end can automatically generate the rule file based on the input required data.

[0096] Among them, the rule file may include one or more rules, and for any rule, it may include a rule body, which may include the various processing steps of the control rule, and the execution units corresponding to the different processing steps in the control rule. In addition, the rule file may also include attribute information of the rule, and the attribute information may include keywords (const), rule names, rule descriptions, rule labels (labels), and the execution order (order) of the rules. Among them, the keywords can be used to characterize the applicable models of the rule, for example, when the keyword is "radar_rule", it can be indicated that the rule is only applicable to radar new energy pickup trucks; the rule name can be unique, and for the same rule name, only the latest rule can be retained in chronological order; the rule label can be represented by a mapping relationship group, for example, by adding a "label-value" key-value pair, a label can be added to the current rule for later management. The rule body can be a rule body written in a high-level language such as Golang. The rule body can support four arithmetic operations (such as addition, subtraction, multiplication, and division), string processing (such as string concatenation), logical operations (such as and, or, not), comparison operations (such as equal to, not equal to, greater than, greater than or equal to, less than, less than or equal to), parentheses, and multi-level calls. For example, the current syntax value is ABC, A is a structure, B is a substructure of A, and C is the specific value of B. Taking A={"name":"radar","info":{"vin":"xxxyyy"}} as an example, then A.info.vin=xxxyyy.

[0097] In addition, before sending a rule update request including a rule file to the rule execution module, the rule design end can also compile the rule file. For example, the rule file can be compiled into a binary file and sent to the rule execution module through steps such as lexical analysis, syntax analysis, and syntax tree parsing.

[0098] When the rule execution module receives the rule update request sent by the rule design end, it can obtain the rule file in the rule update request and update the predetermined control rule and the execution unit corresponding to the predetermined control rule based on the rule file. For example, the rules in the rule file can be converted into the predetermined control rule represented by the Antlr4 script. The update of the predetermined control rule can include addition, deletion, modification, etc. In implementation, the update method can be determined based on the attribute information of each rule in the rule file.

[0099] Therefore, when there is an update to the vehicle's on-board equipment or the operating conditions of the on-board equipment, the predetermined control rules can be automatically updated by updating the rule file without restarting the system. It has good modifiability and great flexibility, and reduces the modification cost of the predetermined control rules, thereby enabling rapid and effective joint control of the on-board equipment.

[0100] In addition, the rule execution module and execution unit library can be wrapped in the context of Golang to improve the security of device linkage control, and can be flexibly deployed in embedded environments, cloud environments, etc. At the same time, Antlr4 can also be used to edit and manage the scheduled control rules. The syntax is simple, and the scheduled control rules can be stored in the form of text, so that they can be flexibly stored in relational or non-relational databases or even file systems, effectively reducing resource requirements.
