The prior art provides a method for representing the state of an industrial production system by using synthetic data obtained by dividing each independent index into sections according to manual experience and weighting and summing the sections. In this way, besides that the manual experience value is difficult to interpret and cannot be quantified, since the industrial production often involves a lot of links, and each experienced operator is only familiar with each link, the experience values of the whole system are difficult to be efficiently connected, and the experience values between the links may be inconsistent. The industrial production system is often influenced by natural conditions such as seasons, climate and the like, artificial experience often has certain hysteresis, and the change of experience values caused by the change of the natural conditions is difficult to capture in time.

Example 1

The embodiment of the disclosure provides a method for registering a sub-device in the Internet of things. The method is applied to a cloud server which is in communication connection with a gateway device.

Specifically, referring to fig. 1, the method for registering the slave device in the internet of things includes:

step S101, receiving a self-registration request of the sub-device from the gateway device.

In one embodiment, the self-registration request of the child device includes: the gateway equipment comprises gateway information, sub-equipment information, a random number and first signature information, wherein the first signature information is generated by the gateway equipment according to the gateway information, the sub-equipment information, the random number and a first pre-acquired sub-equipment model password.

Specifically, referring to fig. 2, fig. 2 is a schematic diagram illustrating an architecture of the internet of things provided in this embodiment. The internet of things comprises afirst sub-device 201, asecond sub-device 202, agateway device 203 and acloud server 204, wherein thegateway device 203 is in communication connection with thecloud server 204, for example, thegateway device 203 and thecloud server 204 establish communication connection through MQTT, and other communication connection modes can be adopted, which is not limited herein. Thecloud server 204 is an execution main body for realizing various services of the service platform of the internet of things, and can realize data control management services. Thefirst sub-device 201 and thesecond sub-device 202 may be in communication connection with thegateway device 203, and thefirst sub-device 201 and thesecond sub-device 202 may indirectly communicate with thecloud server 204 through thegateway device 203. Thecloud server 204 receives the sub-device self-registration request from thegateway device 203, performs self-registration request processing according to the sub-device self-registration request, generates registration information if the sub-device self-registration is successful, thecloud server 204 sends the registration information to thegateway device 203, and thegateway device 203 receives the registration information and stores the registration information.

In this embodiment, the gateway information may include a gateway model identifier and a gateway model password, the sub-device information may include a sub-device model identifier and a sub-device model password, and the random number is a randomly generated random number for signature.

The gateway device is preset with a first sub-device model password, and the generation process of the first signature information may include the following steps:

splicing the gateway information, the sub-device information and the random number according to a preset sequencing rule to obtain first tagging content;

and signing the first signed content by adopting a first sub-equipment model password through a preset signature algorithm to obtain the first signature information.

In this embodiment, the preset sorting rule may be alphabetical sorting of the gateway information and the sub-device information. For example, the first signature information is generated as follows: (1) and sequencing the transmission parameters according to an alphabetic order, and then sequentially splicing the parameters and the values to obtain tagged contents, wherein the transmission parameters comprise gateway information, sub-equipment information and the like, and the transmission parameters do not comprise a signature method (signMethod). (2) For the signed content, signature calculation is carried out by a signed algorithm specified by the signMethod and using a subdevice model cipher (subdellsecret) value of the subdevice: md5(submodel secret & signed content). (3) And taking the calculation result as the value of sign.

The sign value calculation method is exemplified as follows:

md5(subModelSecret&action=subRegister&modelName=gatewayModel001&msgId=4d28c20295d343259a73ad9cab12b502&subModelName=subModel001&subSN=subSN001&tenantId=tenant001&ts=1578032957090)。

where md5 denotes an md5 cryptographic algorithm, subModelSecret denotes a sub-device model password, and "action = subRegister & modelName = gatewayModel001& msgidd =4d28c20295d343259a73ad9cab12b502& subModelName = subModel001& subSN = subSN001& tenentandid = tent 001& ts = 1578032957090" denotes tagged content.

Referring to fig. 3, fig. 3 is another schematic diagram of the architecture of the internet of things, and fig. 3 shows asub-device 301, agateway device 203, acloud server 204, and auser 304. The sub-device model identification and the sub-device serial number can be preset in thesub-device 301, the gateway information and the sub-device information are preset in thegateway device 203, the sub-device model can be created in the cloud server through user operation, and a user can control a self-registration switch of the sub-device model through operating the cloud server and set the sub-device model identification and the sub-device model password by losing the sub-device model. In fig. 3, thegateway device 203 is communicatively connected to thecloud server 204, thegateway device 203 has previously registered a subscription topic (topic) with thecloud server 204, and after thechild device 301 establishes a communication connection with thegateway device 203, thegateway device 203 may initiate a child device self-registration request to thecloud server 204.

It should be noted that, for the case that the sub-device does not preset the sub-device model password, the following processing may be performed:

(1) the sub-device model identifiers and passwords are preset in thegateway device 203, and the method is suitable for the situation that the sub-device models connected with thegateway device 203 are relatively fixed and the security is relatively high.

(2) A sub-device model password is preset in thegateway device 203 for all sub-device models to use, and at the same time, thecloud server 204 also needs to set the same sub-device model password for all corresponding sub-device models, and since the sub-device model suitable for the connection of thegateway device 203 may change, the security of the second method is lower than that of the first method. Therefore, a preset mode of multiple sub-device model passwords is provided, and dynamic registration of the sub-devices is facilitated.

And step S102, generating second signature information according to the gateway information, the sub-device information, the random number and a second pre-acquired sub-device model password.

Referring to fig. 3, after receiving the sub-device self-registration request, thecloud server 204 performs a self-registration processing process, specifically including steps of checking the first signature information and establishing a topological relationship between the sub-device and the gateway device.

In one embodiment, step S102 includes the following steps:

splicing the gateway information, the sub-device information and the random number according to a preset sequencing rule to obtain signed content;

and signing the signed content by adopting a second sub-equipment model password through a preset signature algorithm to obtain second signature information.

It should be noted that, the gateway device and the cloud server are preset with the same preset tagging algorithm, for example, the preset tagging algorithm and the preset md5 algorithm are preset, and the preset tagging algorithm is not limited herein. The gateway device and the cloud server are preset with the same preset ordering rule, for example, both are preset with ordering according to letters, and may also be other ordering rules, which is not limited herein. The generation process of the second signature information may refer to the generation process of the first signature information, and is not described herein again to avoid repetition.

In this embodiment, the sub-device model identifier and the sub-device model password are respectively pre-made in the sub-device and the gateway device to generate the signature verification information, so as to ensure the integrity and the security of the transmission parameters.

Step S103, determining whether the first signature information and the second signature information match.

In this embodiment, the cloud server generates second signature information according to the same rule, and compares the first signature information generated by the gateway device, and if the first signature information matches the second signature information, the verification is passed. According to the generation rule of the signature information, all transmission parameters, the sub-device model key and the random number are included, so that the integrity of the parameters transmitted to the cloud server can be verified and the request authentication can be performed through the signature information, and the safety is improved.

And step S104, if the first signature information is matched with the second signature information, establishing a topological relation between the sub-equipment and the gateway equipment according to the sub-equipment information and the gateway information, and generating sub-equipment registration information.

In this embodiment, the sub-device may obtain the corresponding connection information through gateway dynamic registration, and bind the sub-device to the current grid device connected to the sub-device for networking, thereby effectively improving the connection information issuing process of the sub-device, reducing the time for registering and networking the sub-device, and realizing automatic registering and networking of the sub-device.

In an embodiment, if the first signature information and the second signature information do not match, it indicates that the signature verification fails, and the self-registration process cannot be started. Referring to fig. 3 again, if the registration is unsuccessful or no reply occurs after a timeout, thegateway device 203 initiates a retry policy and resends the child device self-registration request to thecloud server 204.

In an embodiment, after the self-registration request of the child device is verified by thecloud server 204, the child device instance is automatically created by using the serial number of the child device as the model identifier of the child device according to the gateway information and the child device information, and then the networking relationship between the child device and the gateway device is created, that is, the registration of the child device is completed, so as to obtain the registration information of the child device. Referring to fig. 3, thecloud server 204 returns registration information of the child device to thegateway device 203 through the MQTT long connection channel, and thegateway device 203 returns the registration information of the child device to thechild device 301. Thesub-device 301 receives the sub-device registration information and stores the sub-device registration information, and the sub-device 301 needs to take the sub-device information when uploading the working conditions, so that thecloud server 204 can conveniently identify the data of thesub-device 301. Through the communication between thegateway device 203 and thecloud server 204, the dynamic registration and the dynamic networking of the sub-device 301 are completed. In this way, thechild device 301 can update the registration information more safely and effectively, and replace the gateway.

In one embodiment, the self-registration request of the child device further includes: a tenant identification;

before the step of creating the topological relation between the sub-device and the gateway device according to the sub-device information and the gateway information in step S104, the method further includes the following steps:

judging whether the sub-device information is registered in the cloud server;

if the sub-equipment information is not registered in the cloud server, judging whether a sub-equipment model corresponding to the tenant identification starts a self-registration function or not;

and if the sub-equipment model corresponding to the tenant identification starts a self-registration function, skipping and executing the step of establishing the topological relation between the sub-equipment and the gateway equipment according to the sub-equipment information and the gateway information.

The Internet of things platform provided by the cloud server can be rented to different users for data processing, the different users correspond to different tenant identifications, and due to the fact that confidentiality and safety performance of the sub-equipment models are different, the users can control whether the sub-equipment models corresponding to the tenant identifications start the self-registration function or not. Specifically, referring to fig. 3 again, if the user opens the self-registration switch of the sub-device model after creating the sub-device model through the cloud server, the sub-device model starts the self-registration function, and the user sets the sub-device model identifier and the sub-device model password of the sub-device model through the cloud server.

In an embodiment, the step of creating a topological relationship between the sub-device and the gateway device according to the sub-device information and the gateway information includes:

using the sub-equipment serial number as a sub-equipment instance identifier, searching a target sub-equipment model according to the sub-equipment instance identifier, and creating a sub-equipment instance under the target sub-equipment model according to the sub-equipment instance identifier;

and creating a topological relation between the sub-equipment and the gateway equipment according to the sub-equipment instance and the gateway information.

Specifically, the gateway device instance may be obtained according to the gateway information, and the gateway device instance may be bound to the sub-device instance to obtain the topological relationship between the sub-device and the grid device. It should be noted that the creation process of the gateway device instance may include the following steps: the cloud server creates a gateway device instance corresponding to a real gateway device in the real physical world according to the gateway information and the gateway device model by creating the gateway device model including all attribute parameters of the gateway device.

In an embodiment, before the step of determining whether the child device information is registered in the cloud server, the method further includes:

creating the sub-equipment model, and starting a self-registration function of the sub-equipment model;

and setting corresponding sub-equipment model identification and sub-equipment model passwords for the sub-equipment model.

In this implementation, the sub-device model is an object model of a class of sub-devices, the sub-device model includes all attribute parameters of the class of sub-devices, multiple sub-device instances can be bound under the sub-device model, each sub-device instance corresponds to a real sub-device in a real physical world, and each sub-device instance is correspondingly provided with a sub-device model identifier and a sub-device model password. The child device model may include: the sub-device models of the sensor class, the sub-device models of the collector class, and the like are not limited herein. In this way, dynamic registration of various sub-devices can be achieved.

In the method for registering a slave device in the internet of things provided by this embodiment, a slave device self-registration request is received from the gateway device; generating second signature information according to the gateway information, the sub-device information, the random number and a pre-acquired second sub-device model password; judging whether the first signature information and the second signature information are matched; and if the first signature information is matched with the second signature information, establishing a topological relation between the sub-equipment and the gateway equipment according to the sub-equipment information and the gateway information, and generating sub-equipment registration information. Therefore, the gateway device is communicated with the cloud server, dynamic registration and dynamic networking of the sub-devices are automatically completed, and automatic networking of the sub-devices in the Internet of things can be realized more safely and effectively.
