Description

Technical Field

[0001] The invention relates to the technical field of digital electronic detonators, and in particular to a digital electronic detonator detonation control method, device and system based on double password verification. Background Art

[0002] At present, electronic detonators have completely replaced ordinary industrial detonators in the domestic market. Electronic detonators have certain advantages in delay accuracy, safety, detectability, etc., especially the three-code binding and password-authorized detonation control mechanism, which enhances the safety control of the entire life cycle of electronic detonator production, circulation, and use, and plays a significant role in maintaining social security. However, we have to admit that the problem of whether or not electronic detonators exist has only been solved so far. There are some violations in the production code injection, three-code binding and uploading, password downloading, and blasting use. For example: the detonation password is too simple or the detonation password is not randomly generated, and can be deduced through information such as the UID code or shell code; dual-password detonation, the electronic detonator can be detonated with a normal password or a private password; no-password detonation, the backdoor detonation command can still detonate the electronic detonator even if the password is not successfully verified; the password is visible or rewritable, and the password can be directly read or a new password can be directly written through the backdoor command; the password is retained, and the password information is obtained through the electronic detonator communication information analysis, and saved to the self-built password management system for self-use; and some chip manufacturers first download the password through their own platform, and after completing the detonation, they complete the process through the password downloading platform, resulting in the safety hazard of uncontrolled use and loss of electronic detonators.

[0003] In response to the above violations, measures such as the electronic detonator password management center, three-code control terminals, and related industry standards and testing methods have been able to plug these loopholes to the greatest extent possible from the software and regulatory levels. However, due to the complexity and hidden nature of the electronic detonator control module hardware technology, electronic detonator control module manufacturers may still actively design hardware backdoors, and regulatory authorities cannot effectively find these hardware backdoors through technical means, making it easy for electronic detonators to escape supervision. This will cause safety hazards such as illegal loss of electronic detonators and uncontrolled detonation. Summary of the invention

[0004] The purpose of the present invention is to propose a digital electronic detonator detonation code control system, a control method, a detonation method and a corresponding device, to improve the control mechanism and communication mechanism of the detonation code corresponding to the digital electronic detonator detonation network, and to solve the problems mentioned in the background technology.

[0005] On the one hand, the present invention provides a digital electronic detonator detonation control method based on double password verification, which generates a first dynamic password and a second dynamic password corresponding to the digital electronic detonator and the detonator; and compares the first dynamic password with the second dynamic password to confirm whether to ignite the detonator.

[0006] On the other hand, the present invention provides a digital electronic detonator detonation control device based on double password verification, and utilizes a digital electronic detonator detonation control method based on double password verification to complete the confirmation and control of the ignition and detonation of the digital electronic detonator.

[0007] On the other hand, the present invention also provides a digital electronic detonator detonation control system based on double password verification, comprising an initiator and a digital electronic detonator group composed of a plurality of digital electronic detonators. The digital electronic detonator detonation control system is used to realize the confirmation and control of the initiator on the ignition and detonation of one or more digital electronic detonators.

[0008] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0009] The digital electronic detonator detonation control scheme based on double password verification provided by the present invention improves the password verification mechanism of the detonator to confirm the detonation of the digital electronic detonator, avoiding the hidden hardware backdoor that may be obtained when the detonator is ignited, so that the electronic detonator cannot be illegally detonated when the detonator password fails to verify the password, and then combined with the supervision cloud server, three-code control terminal and relevant industry standards and detection means and other measures, it can effectively prevent the detonation violation operation and illegal detonation. In the improved scheme, some key and other data are pre-written and cannot be modified later, which can avoid insufficient password valid bits and non-random generation, and prevent the loss of traceability information, so that the supervision is efficient and unified, and effectively eliminates the illegal phenomena such as double passwords, visible passwords, and passwords that can be rewritten. In addition, the password transmission and verification between the supervision cloud server and the detonator, and between the detonator and the digital electronic detonator are all encrypted, and the real password information cannot be obtained by analyzing or cracking the electronic detonator communication information, which can effectively eliminate the illegal phenomenon of password retention.

[0017] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0018] Embodiment 1

[0019] The existing digital electronic detonator detonation network generally consists of an initiator 101 and a digital electronic detonator group 201 composed of a plurality of digital electronic detonators 202 controlled by the initiator 101. Figure 1 The detonator 101 includes a detonator control board 102, and each digital electronic detonator 202 includes an electronic detonator control module 203 and a basic detonator 204. In the working state, the digital electronic detonator 202 communicates and processes with the detonator control board 102, thereby completing tasks such as circuit status reading and detonation.

[0020] like Figure 2As shown, a digital electronic detonator detonation control system based on double password verification after improvement in an embodiment of the present invention is shown. The detonator control board 102 of the detonator 101 includes a detonation control main board circuit 104 and a detonation control password module 103, and the detonation control password module 103 at least includes a second dynamic password generation unit 105, and has a unique identification code and a decryption key for password decryption and password operation.

[0021] Similarly, the improved electronic detonator control module 203 includes a detonator control main chip 205 and a detonator control password module 206. The detonator control main chip 205 at least includes an ignition control unit 207, which is used to control the ignition function according to the double password verification result. The detonator password control module 206 at least includes a first dynamic password generation unit 208 and a password verification unit 209, which are used to store the UID code and the detonation password and complete the detonator password calculation, password verification and other functions. In a preferred embodiment, the detonation control password module 103 and the detonator control password module 206 can be dedicated chips or circuit units with corresponding functions.

[0022] When the detonator 101 and the digital electronic detonator 202 perform data communication and transmission, it is mainly realized through the communication system between the detonator control board 102 and the electronic detonator control module 203, especially the one-to-one communication system between the detonation control main board circuit 104 and the detonator control main chip 205 continues to serve as the communication medium between the detonation control password module 103 and the detonator control password module 206, and the communication data is forwarded to enable the detonation control password module 103 and the detonator control password module 206 to achieve two-way communication.

[0023] Embodiment 2

[0024] Based on the improved digital electronic detonator detonation control system based on dual password verification described in the above embodiments, the core functions such as dual dynamic password generation, dual password verification, password information storage, circuit state reading, detonation confirmation, etc. can be completed under the mutual cooperation of the improved module units, thereby realizing highly safe control and effective supervision of electronic detonators. This embodiment specifically describes the above module unit structure and corresponding functions.

[0025] The improved digital electronic detonator initiation control system adopts a dual dynamic password verification mechanism to control initiation to prevent safety hazards such as uncontrolled initiation.

[0026] First, the detonation control password module 103 added to the detonator control board 102 of the detonator 101 can generate a corresponding verification password during detonation verification and control, and is used to cooperate with the detonation control main board circuit 104 to control whether to detonate the detonation object. The detonation control password module 103 at least includes a second dynamic password generation unit 105, which is used to store the relevant data of password generation and generate a second dynamic password 404, which is used as a comparison password in the dual dynamic password verification mechanism.

[0027] Secondly, a detonator control password module 206 is added to the improved electronic detonator control module 203. The difference from the prior art is that the detonator password control module 206 can automatically and randomly generate a new first dynamic password 304 each time the digital electronic detonator 202 is powered on again. The first dynamic password 304 is used as the reference password in the dual dynamic password verification mechanism.

[0028] Specifically, the detonator password control module 206 at least includes a first dynamic password generation unit 208, a password verification unit 209 and a password storage unit 210. The password storage unit 210 is used to store relevant preparation data for password generation, including at least UID code, shell code, random plain code, key, etc. The first dynamic password generation unit 208 is used to generate a first dynamic password 304 according to relevant data, and the first dynamic password 304 is used as a reference password in the dual dynamic password verification mechanism. The password verification unit 209 is used to compare the first dynamic password 304 with the second dynamic password 404 from the detonator 101. If the data of the first dynamic password 304 and the second dynamic password 404 are completely consistent, the password verification is successful, and the detonation confirmation can be performed at this time; if there is any difference between the two data, the password verification fails and the detonation cannot be completed.

[0029] The detonator control main chip 205 includes an ignition control unit 207 for confirming whether to ignite the digital electronic detonator 202 according to the double password verification result of the first dynamic password 304 and the second dynamic password 404 .

[0030] Embodiment 3

[0031] Based on the improved digital electronic detonator detonation control system based on dual password verification described in the above embodiments, the core functions such as dual dynamic password generation, ignition control, password verification, and password information storage can be completed under the cooperation of the improved module units, thereby achieving highly safe control and effective supervision of electronic detonators. The present invention will explain how to implement the above functions and the corresponding operations one by one through multiple embodiments.

[0032] The improved digital electronic detonator detonation control system adopts a dual dynamic password verification mechanism to control ignition to prevent the password information from being obtained through analysis of the communication information of the digital electronic detonator and retained for self-use. Therefore, each time the system is powered on, the digital electronic detonator 202 and the detonator 101 are designed to regenerate a new dynamic password and use it for dynamic verification.

[0033] Specifically, after the digital electronic detonator 202 is initialized and started, the first dynamic password generation unit 208 included in the detonator password control module 206 automatically and randomly generates a new first dynamic password 304 each time the detonator is powered on again, and invalidates the first dynamic password 304 used previously.

[0034] like Figure 3 As shown, in order to generate the first dynamic password 304, the first dynamic password generation unit 208 needs to prepare a random plain code 301 and a key A302. The random plain code 301 is a set of random numbers, and the random plain code 301 will be automatically updated each time the power is turned on again. The key A302 is a set of unique fixed data stored in the detonator control password module 206. The fixed data key A302 is different in each digital electronic detonator 202 and is not visible to the outside. It is randomly written and locked by the initial supervision writing module, so that the key A302 cannot be rewritten by a third party after being written into the digital electronic detonator 202.

[0035] In addition, each digital electronic detonator 202 has a unique, one-to-one digital identity number, namely, a UID code. The detonator 101 can select the digital electronic detonator 202 corresponding to the UID code by dialing the UID code through communication and conduct one-to-one communication. The UID code is generally compiled according to certain rules. Usually, a complete UID code includes UIDA305 and UIDB406. Among them, UIDA305 is used by the detonator 101 to identify the identity of the digital electronic detonator 202 and use UIDA305 to dial and select the target digital electronic detonator 202 during the communication process, and download the password generation required data, such as key A302, etc., to the supervision cloud server 501 through UIDA305, and then use the data corresponding to UIDA305 to calculate the second dynamic password 404 for verification.

[0036] The UIDA 305 is a unique identification code for each digital electronic detonator 202 and is also written and locked by the initial supervision writing module. The binding data of the key A 302 and the UIDA 305 is properly stored by the password storage unit 210 .

[0037] When generating the first dynamic password 304, the detonator 101 first obtains the corresponding key A302 through the selected UIDA305, and determines the first encryption algorithm 303, and then encrypts the random plaintext 301 and the key A302 through the first encryption algorithm 303 to obtain the encrypted first dynamic password 304. In a preferred embodiment, the encrypted first dynamic password 304 can be further bound to the UIDA305.

[0038] In the detonator control password module 206, the above-mentioned random password generation mechanism can effectively prevent cracking: on the one hand, the selection of the first encryption algorithm 303 is made more rigorous and secure. Even if a third party knows the first encryption algorithm 303, it is impossible to reversely deduce the key A302 through the random plain code 301 and the first dynamic password 304, and it is impossible to find a cracking algorithm to deduce the first dynamic password 304 based on the random plain code 301; on the other hand, the period of the random plain code 301 is made long enough, and brute force cracking cannot be achieved by traversing all possible random plain codes 301.

[0039] At the same time, before detonation and ignition are required, the second dynamic password generation unit 105 included in the detonation control password module 103 needs to generate a random dynamic password that is the same as the current one in the target detonator password control module 206 in order to successfully perform double password verification on the digital electronic detonator 202.

[0040] like Figure 4 As shown in the flowchart, in order to generate the second dynamic password 404, the relevant data that the second dynamic password generation unit 105 needs to prepare includes, in addition to the random plain code 301 and the key A302, the encrypted key 401 and the key B402. The key B402 is a set of unique fixed data stored in the detonation control password module 103. The fixed data is unique in the detonator control board 102 and is invisible to the outside. It is randomly written and locked by the initial supervision write module, so that the key B402 cannot be rewritten by a third party after writing. In addition, the detonation control password module 103 also stores a unique identification code UIDB406, which is also written and locked by the initial supervision write module. The binding data of the key B402 and UIDB406 is properly stored by the supervision cloud server 501.

[0041] The method for obtaining the encrypted key 401 is as follows: before each blasting password verification, the supervision cloud server 501 queries the key B402 bound to UIDB406 and the key A302 bound to UIDA305 in the database, and then encrypts the key B402 and the key A302 through the second encryption algorithm 405 to obtain the encrypted key 401, and then sends the encrypted key 401 together with other relevant data in the form of a work code to the detonator control board 102 corresponding to UIDB402, and is called by the detonation control password module 103 as needed.

[0042] After obtaining the encrypted key 401, the detonator control password module 103 first decrypts the encrypted key 401 and the key B402 using the second decryption algorithm 403 to obtain the key A302, and then encrypts the random plaintext 301 and the key A302 using the first encryption algorithm 303 to obtain a random second dynamic password 404.

[0043] In a preferred embodiment, the UIDA 305 is obtained by the target digital electronic detonator 202 from the supervision cloud server 501, and the UIDB 402 is provided by the terminal detonator 101. In another preferred embodiment, since the terminal detonator 101 is uniquely bound to the target UIDB 402, only the information of the detonator 101 may be provided to the supervision cloud server 501.

[0044] For the generated first dynamic password 304 and second dynamic password 404, when it is necessary to confirm the ignition of the digital electronic detonator 202, a double password verification operation must be performed first, that is, it is necessary to confirm that the second dynamic password 404 generated by the initiator 101 for the target digital electronic detonator 202 is a random password that is completely consistent with the currently generated first dynamic password 304 in the target digital electronic detonator 202, so that the password can be successfully verified. The specific operation is that in the target detonator control password module 206, the second dynamic password 404 processed by the detonation control password module 103 and the first dynamic password 304 processed by the target detonator control password module 206 are compared by the password verification unit 209. If the two password data are completely consistent, the double password verification is successful, and if there is any difference in the data, the double password verification fails.

[0045] In a preferred embodiment, the second decryption algorithm 403 is the inverse operation of the second encryption algorithm 405 .

[0046] In the detonation control password module 103, the above-mentioned random password generation mechanism can effectively prevent the control board card password from being cracked: the selection of the second decryption algorithm 403 is made more rigorous and secure. Even if the second decryption algorithm 403 is informed and the key A302 is illegally obtained, the key B402 cannot be reversely deduced through the encrypted key 401 and the key A302, and it is impossible to find a cracking algorithm to deduce the key A302 based on the encrypted key 401.

[0051] The password verification unit is used to compare the first dynamic password 304 with the second dynamic password 404; if the data of the first dynamic password 304 and the second dynamic password 404 are completely consistent, the password verification is successful and the detonation confirmation is performed; if there is any difference between the data of the first dynamic password 304 and the second dynamic password 404, the password verification fails and the detonation control cannot be completed.

[0052] Furthermore, another embodiment of the present application provides a digital electronic detonator blasting network communication device based on double password verification, wherein the digital electronic detonator blasting network communication device includes at least the double random password generating device in any of the aforementioned embodiments, and performs network communication of password data.

[0053] It should be noted that the specific working processes of the various modules, units, and devices provided in the above embodiments of the present application can refer to the corresponding steps in the above method embodiments, and will not be repeated here.

[0054] Another embodiment of the present application provides an electronic device, including: a memory and a processor.

[0055] Among them, the memory is used to store programs.

[0056] The processor is used to execute the program. When the program is executed, it is specifically used to implement the digital electronic detonator detonation network control method and / or communication method based on double password verification as provided in any one of the above embodiments.

[0057] Another embodiment of the present application provides a computer storage medium for storing a computer program. When the computer program is executed, it is used to implement a digital electronic detonator detonation network control method and / or communication method based on double password verification as provided in any of the above embodiments.

[0058] Computer storage media includes permanent and non-permanent, removable and non-removable media that can be implemented by any method or technology to store information. Information can be computer-readable instructions, data structures, program modules or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technology, compact disk read-only memory (CD-ROM), digital versatile disk (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices or any other non-transmission media that can be used to store information that can be accessed by a computing device. As defined herein, computer-readable media does not include temporary computer-readable media (transitory media), such as modulated data signals and carrier waves.

[0059] Those skilled in the art may further know that the units and algorithm steps of each example described in conjunction with the embodiments disclosed herein can be implemented in electronic hardware, computer software, or a combination of the two. In order to clearly illustrate the interchangeability of hardware and software, the composition and steps of each example have been generally described in the above description according to function. Whether these functions are performed in hardware or software depends on the specific application and design constraints of the technical solution. Those skilled in the art may use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of this application.

[0060] In summary, the present invention proposes an improved digital electronic detonator detonation control system and control method based on double password verification, which only requires a small modification on the basis of the existing digital electronic detonator structure, and does not change the core contents such as the communication protocol of the original digital electronic detonator solution, so as to facilitate the adaptation of various original electronic control modules and control boards, etc. When necessary, the system can seamlessly switch between the original working mode and the improved detonation control working mode.

[0061] The detonator password control module can provide additional storage space for storing various data information required by the detonator password control module, so that the main chip of the digital electronic detonator no longer needs to integrate expensive non-volatile memory, which can reduce the manufacturing cost of the digital electronic detonator and only increase the computing power consumption by a small amount. The chip of the digital electronic detonator can easily achieve the goals of low cost, low power consumption, and high reliability, making the overall cost and power consumption increase of the chip encryption solution small to completely acceptable, and the overall reliability loss can be ignored.

[0062] In the improved digital electronic detonator detonation control scheme based on double password verification, the password, key, UID code and other data are pre-written and managed by the supervision writing module. After write protection, no third party can modify it, which can avoid insufficient effective bits of the password and non-random generation, and prevent the loss of traceability information, making supervision efficient and unified, and effectively eliminating violations such as double passwords, visible passwords, and passwords that can be rewritten. In addition, the password transmission and verification between the supervision cloud server and the detonator, and between the detonator and the digital electronic detonator are encrypted, and the real password information cannot be obtained through electronic detonator communication information analysis or cracking, which can effectively eliminate the violation of password retention.

[0063] In addition, the improved digital electronic detonator detonation control scheme based on double password verification does not have hidden hardware backdoors. Only the detonator specified when applying for the detonation password (encrypted key A) can decrypt the correct password and further successfully detonate the corresponding digital electronic detonator. Therefore, the electronic detonator cannot be illegally detonated when the detonator password fails to verify the password. Combined with the supervision cloud server, three-code control terminal, and relevant industry standards and detection methods, it can effectively prevent illegal detonation operations and illegal detonation.

[0064] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be thought of by a person skilled in the art within the technical scope disclosed by the present invention without creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
