Problems solved by technology

[0003] The existing patent with the publication number CN105334798A "An Automatic Piece Counting Method and System for CNC Machine Tool Workshop" discloses a technical solution for recording the completed workpiece information through the piece counting unit, but no confidentiality measures are taken in the piece counting process , there are operational loopholes, and the disclosed content fails to solve the problem of fee settlement. Therefore, although this technical solution provides the completed workpiece through the piece unit record, it still cannot be used to solve the problem of automation equipment rental charges

Embodiment 1

[0037] see figure 1 with figure 2 , a kind of industrial software piece count encryption method, comprises the steps:

[0038] Step 10, judging whether settlement is required according to piece count information and settlement threshold; if settlement is not required, execute step 20; if settlement is required, execute step 30;

[0039] Step 20, the measurement and control circuit board 1 detects the counting unit 2, and the state of the counting unit 2 changes once every time the equipment is processed. The piece count information and the settlement threshold are stored in a storage space that ordinary users cannot access, and then return to step 10;

[0040] Step 30, read the hardware device information on the computer 3 as the first plaintext, take the piece counting information as the second plaintext, use the first plaintext and the second plaintext as input, and run an encryption algorithm to generate a key;

[0041] Step 40, after the user settles with the equipment...

Embodiment 2

[0046] see figure 1 with image 3 , this embodiment includes the operation steps when the system is just started, and the specific implementation of judging whether settlement is required, as follows:

[0047] Step 00, check whether the measurement and control circuit board 1 and the servo driver 4 on the system are normally connected and communicated, if so, read the piece counting information stored on the computer 3, and send the piece counting information to the measurement and control circuit board 1 through the industrial bus; If not, the industrial software is exited; the measurement and control circuit board 1 and the servo driver 4 are connected and communicated with the computer 3 through an industrial bus (such as EtherCAT, Profinet, etc.); the measurement and control circuit board 1 is also connected to the servo driver 4, and the servo driver 4 The motor 5 is a component on the automation equipment, and the servo driver 4 is used to drive the servo motor 5 to mak...

Embodiment 3

[0054] see figure 1 with Figure 4 , an industrial software piece counting encryption system, including a judgment module, a piece counting module, a key generation module and a verification module, specifically as follows:

[0055] Judgment module: it judges whether settlement is required according to piece counting information and settlement threshold; if settlement is not required, run the piece counting module; if settlement is required, run the key generation module;

[0056] Piece counting module: the measurement and control circuit board 1 detects the counting unit 2. Every time the equipment is processed, the state of the counting unit 2 changes once. After the measurement and control circuit board 1 detects the state change, the measurement and control circuit board 1 updates the piece counting information once, and the piece counting module will settle Threshold and piece count information are stored in a storage space that ordinary users cannot access, and then run...

Abstract

The invention relates to an industrial software number counting encryption method and system; whether a user needs to settle a fee or not is judged according to number counting information and a settlement threshold value; if settlement is needed, the hardware information and the number counting information of a computer equipped with industrial software are taken as input, and an encryption algorithm is operated to generate a secret key; the user obtains a password after settling the fee with a device providing manufacturer; the generation mode of the password is the same as that of the private key; the password is consistent with the secret key, and the device can continue to work normally. The invention relates to an industrial software number counting encryption system. according to the method and the system in the invention, the industrial software can be encrypted, and the number encryption can be realized; after a certain number of workpieces are processed, the user needs to obtain the secret key to continuously use the device after payment settlement to the device manufacturer; and the method and the system can be widely applied to the fields of renting of industrial automatic devices, MES systems and the like.

Description

technical field [0001] The invention relates to an industrial software piece count encryption method and system, belonging to the field of computer industrial control. Background technique [0002] With the increase of labor costs, various computer-controlled automation equipment has been widely used in industrial production. Due to the rapid product replacement, strong specialization of automation equipment, and high one-time investment costs, many equipment manufacturers prefer to rent manufacturers. equipment, and pay the equipment rental fee to the equipment manufacturer on a piece-by-piece basis. Therefore, equipment manufacturers need an encryption mechanism. When the number of pieces produced reaches a certain number, the software of the automation equipment will fail, and the equipment manufacturer will be prompted to settle the payment. [0003] The existing patent with the publication number CN105334798A "An Automatic Piece Counting Method and System for CNC Machi...
