Embodiment 1

[0055] When the signal is unstable, the cloud will randomize 4 digits and try to download it several times without success; then the password will be generated according to the serial number of the IoT module + a specific algorithm. Here is an example:

[0056] (1) Cloud:

[0057] Step 1: The cloud obtains the serial number from the device controller through the IoT module, such as: 2010010001; (the serial number of the module is a ten-digit ID, and the serial number of each module will be different);

[0058] Step 2: Add the obtained serial number to a fixed 9-digit number, assuming that the fixed 9-digit number is: 123456789; then the serial number 2010010001+123456789= 2133466790; where 123456789 is the agreed value between the cloud and the controller, and this value can be passed through artificial modification;

[0059] Step 3: Take the 5th, 6th, 9th, and 10th digits and spell them into four digits; for example, the 5th digit of 2133466790 is 4, the 6th digit is 6, the ...

Embodiment 2

[0069] When the signal is unstable, the cloud will randomize 4 digits and try to download it several times without success; then the password will be generated according to the serial number of the IoT module + a specific algorithm. Here is an example:

[0070] (1) Cloud:

[0071] Step 1: The cloud obtains the serial number from the device controller through the IoT module, such as: 2010010001; (the serial number of the module is a ten-digit ID, and the serial number of each module will be different);

[0072] Step 2: Add a random 9-digit number to the obtained serial number, assuming that the 9-digit random password is: 123456789, 787645321; then select a set of data from the data each time, such as 123456789; then the password generation method is:

[0073] Serial number 2010010001+123456789= 2133466790;

[0074] Step 3: Take the 5th, 6th, 9th, and 10th digits and spell them into four digits; for example, the 5th digit of 2133466790 is 4, the 6th digit is 6, the 9th digit i...

Embodiment 3

[0084] When the signal is stable, the cloud generation method is as follows:

[0085] Step S01, triggering on the application side: when an electromechanical device needs to be operated, the user clicks on the application side to generate a dynamic password, and then calls the cloud data;

[0086] Step S02, the cloud generates a random dynamic password: the cloud generates a random 4-digit password through a password generation algorithm; wherein the dynamic code is a four-digit random number generated by the random method in the Math class of Java;

[0087] Step S03, the cloud issues the password to the IoT module: the cloud issues a 4-digit password to the IoT module through MQTT or HTTP, and the IoT module receives it through a wireless signal; after receiving it, the IoT module then passes the industrial communication Write to the device controller, when the signal is written successfully, the device can be turned on and working;

[0088] From the above, in the case of st...

Abstract

The invention belongs to the technical field of Internet-of-Things control, and discloses a dynamic password implementation method under the condition of an unstable wireless signal, and the method comprises the following specific steps: S01, triggering an application end: enabling a user to click the application end to generate a dynamic password when one electromechanical device needs to be operated, and calling cloud data; and S02, enabling the cloud to generate a random dynamic password, and enabling the cloud to generate a random four-digit password through a password generation algorithm. According to the invention, by setting the dynamic code, the effectiveness of a dynamic password mechanism is realized for electromechanical equipment under the condition that a field wireless signal is unstable; in addition, through the implementation method of the dynamic password, the electromechanical equipment is prevented from being maliciously controlled, the equipment operation quality is improved, and the safety of the electromechanical equipment is ensured.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things control, and in particular relates to a method for realizing a dynamic password in the case of unstable wireless signals. Background technique [0002] Electromechanical equipment widely exists in factory workshops, some of which have extremely high value or affect direct production, so if the equipment is not properly controlled, it will cause very large losses. For example: equipment damage, production stoppage, production of defective products and many other unfavorable losses. Generally, manufacturers will set a general factory password, but this password is a constant static password, so it is extremely unsafe. We use a number of combined technologies: Internet of Things, cloud computing technology, wireless communication, industrial communication to realize dynamic passwords to ensure the security of passwords. However, the industrial site where the electromechanical equipment i...
