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, perform step 20; if settlement is required, perform step 30;

[0039] Step 20: 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 piece counting information is updated once, and then sent to the computer 3. 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 pl...

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 piece counting encryption method. According to the piece counting information and the settlement threshold, it is judged whether the user needs to settle the fee. If settlement is required, the hardware information of the computer equipped with the industrial software and the piece counting information are used as input together, and an encryption algorithm is run to generate A key, the user provides the device to the manufacturer to obtain a password after settlement. The password is generated in the same way as the key. If the password is consistent with the key, the device can continue to work normally. The invention relates to an industrial software piece count encryption system. The invention can not only encrypt industrial software, but also realize quantity encryption. After processing a certain number of workpieces, the user needs to pay and settle with the equipment manufacturer to obtain the key before continuing to use it. It can be widely used in industrial automation equipment rental, MES systems and other fields.

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...
