Description
Technical Field
The invention relates to monitoring and management of civil explosive material products, in particular to a design of an electronic detonator supervision system and a method for monitoring and managing the use process of an electronic detonator by using the system.
Background
The detonator is a detonating element which outputs detonation energy under the excitation of a small ignition impulse energy, and is an excitation source for the explosion action of other explosive substances such as explosives and the like. Therefore, the monitoring and management of the information flow direction of the industrial detonator is always the most important in the monitoring and management work of the civil explosive device products.
At present, in the detonator production process, China adopts a coding marking technology of mechanical indentation or laser engraving, then converts detonator coding information through a bar code technology, collects and records the coding information into a computer management system, establishes a corresponding computer management system at an explosive circulation, use and supervision department, and establishes a corresponding forced execution management flow. When in sale and circulation, the detonator coded information is bound with an explosion-related unit or an explosion-related person through an IC card, and a new message about detonator circulation is generated while the goods are circulated, so that the whole process of production, circulation and use of each detonator is under the supervision of a computer of a management department.
The management method for detonator coding realizes the monitoring and management of detonator production and circulation links, but cannot prevent the detonator from being illegally used. Firstly, because the traditional electric detonator is powered on and then detonated, the monitoring management department cannot monitor the detonation process of the detonator. Secondly, the detonator is broken into fragments after explosion, the 'code' does not exist any more, and the source of the detonator is difficult to trace by monitoring and managing departments. Thirdly, the information input in each circulation link has strong dependence on people, so that the management link has the possibility of information error or loss caused by human factors. In addition, the code printing is carried out in the detonator production process, so that the production process of the detonator is increased, and the physical code printing mode can also pose a potential threat to the safety of detonator production.
In the 80 s of the 20 th century, developed countries and regions such as japan, australia, and europe began to study electronic detonator technology. Based on two-way communication between a blasting information monitoring management data center and an electronic detonator initiation device, patent application document 200910000065.5 discloses a system capable of monitoring and managing an electronic detonator initiation network, which realizes monitoring of the validity of the use process of an electronic detonator by monitoring and managing information such as the identity validity of a detonator product, the validity of an initiation device, the validity of initiation operators, the validity of initiation positions, the validity of initiation time and the like, and finally realizes control and management of the initiation process of the electronic detonator by authorization control of the initiation device through the data center.
In the monitoring management system, the data center directly carries out remote monitoring management on the detonation process, the legality of the detonation process is monitored, and a party requiring the data center to obtain the detonation device can execute corresponding operation. However, the solution has the following defect that the communication between the initiation device and the data center depends on a wired network or a wireless network, so that when the blasting is performed in an environment with poor communication conditions or unsmooth network transmission, the initiation device and the data center cannot normally communicate, which may cause the system to fail to normally complete the request and authorization for initiation, thereby causing the possibility that the legal blasting cannot be normally performed.

As shown in fig. 2, the detonating device 300 may include a control module 301, a computer communication interface 302, a power management module, a signal modulation transmission module, a signal demodulation reception module, and a power source. Wherein the computer communication interface 302 may be used to enable data interaction between the initiation device 300 and the authorization device 200.

Wherein, the power conversion circuit 201 is connected to the modules and supplies power to the modules; the other end of the power conversion circuit 201 is connected to a power supply outside the authorization apparatus 200, and receives power from the external power supply. The remaining two terminals of the control circuit 204: one end is connected to the communication interface circuit 202, and the other end is connected to the nonvolatile memory 203. The control circuit 204 controls the communication interface circuit 202 to perform data interaction with the external data center 100 or the initiation device 300, on one hand, stores the information on the blasting authorization sent by the data center 100 or the initiation information sent by the initiation device 300 into the nonvolatile memory 203, and on the other hand, sends the information stored in the nonvolatile memory 203 to the data center 100 or the initiation device 300. The other end of the communication interface circuit 202 is a communication end 22, which is connected to the outside of the authorization device 200 to realize data interaction with the data center 100 or the initiation device 300.
If the data center 100 and the initiating device 300 communicate with the authorizing device 200 in different signal forms, the signals output by the data center 100 or the initiating device 300 can be converted into signals recognizable by the authorizing device 200 by using a built-in or external signal conversion interface by using a well-known signal conversion technology to complete the communication. In addition to this, the following modifications can be made to the authorization device: as shown in fig. 4, the authorization device may include a control circuit 204, a non-volatile memory 203, a communication interface circuit 202', and a power conversion circuit 201. The communication interface circuit 202' may further include a communication interface 207, a communication interface 208, and a communication interface switching circuit 206, among others. The specific connection relationship is as follows: the power conversion circuit 201 is connected to the control circuit 204, the nonvolatile memory 203, the communication interface 207, and the communication interface 208, and supplies power to the above modules; the other end of the power conversion circuit 201 is connected to a power supply outside the authorization apparatus 200, and receives power from the power supply. The control circuit 204 is also connected to the communication interface 207 and the communication interface 208, respectively, and the remaining end of the control circuit 204 is connected to the nonvolatile memory 203. One end of the communication interface switching circuit 206 is connected to the other end of the communication interface 207, and the other end is connected to the other end of the communication interface 208, and the other two ends of the communication interface switching circuit 206 are respectively led to the outside of the authorization apparatus 200, and respectively constitute the control end 23 and the communication end 22 of the authorization apparatus 200.
With the embodiment shown in fig. 4, when the authorization apparatus 200 communicates with the outside, the communication interface switching circuit 206 is used to switch the branch connected to the communication interface 207 and the branch connected to the communication interface 208. For example, the system may be designed to: when the authorization apparatus 200 communicates with the data center 100, the control terminal 23 of the authorization apparatus 200 is connected to a low level, and the branch of the communication interface switching circuit 206 connected to the communication interface 208 is turned on; when the authorization device 200 communicates with the initiation device 300, the control terminal 23 of the authorization device 200 is high, and the branch of the communication interface switching circuit 206 connected to the communication interface 207 is turned on. This allows for flexible switching of the authorization apparatus 200 between different communication modes.
If the data center 100 or the initiating device 300 cannot provide the exact high-low level control signal to the control terminal 23 of the authorization device 200 during the communication process, a pull-up circuit or a pull-down circuit may be further designed based on the scheme shown in fig. 4, and the exact high-level or low-level control signal is provided to the communication interface switching circuit 206 through the pull-up or pull-down action. For example, in the embodiment shown in fig. 12, a pull-up circuit 205 is designed to be connected between the control terminal 23 and the output of the power conversion circuit 201, so that when the control terminal 23 is in an indeterminate state, the pull-up circuit 205 will provide a definite high-level signal to the control terminal 23, thereby controlling the gating branch of the communication interface switching circuit 206.
The pull-up circuit or the pull-down circuit in the above embodiments may be designed inside the authorization device or outside the authorization device, and the technical effects are the same.

fourthly, receiving detonation information sent by the detonation device 300 and storing the detonation information in the nonvolatile memory 203;
step five, sending detonation information to the data center 100;
and sixthly, ending the authorization monitoring process of the authorization device.
As another aspect of the initiation authorization monitoring and managing method of the present invention, corresponding to the authorization device authorization supervision process shown in fig. 5, the initiation device 300 executes an initiation authorization request process to request initiation authorization from the authorization device 200 according to the following steps, as shown in fig. 6:
firstly, the control module 301 obtains relevant information of the current detonation system, namely information of the detonation system, and sends the information to the authorization device, and the authorization device checks the information;
step two, the control module 301 monitors whether the information returned by the authorization device 200 is received: if so, performing the third step; otherwise, continuing to monitor reception;

(2) The authorization device 200 executes a process for checking the information of the detonation system, checks the information of the detonation system according to the blasting authorization information sent by the data center 100, and accordingly judges the validity of the detonation. In the authorization apparatus 200, the corresponding contents in the detonation system information and the blasting authorization information are compared one by one. After checking, if the information of the detonating system is qualified, the authorization device 200 sends an information checking qualified signal to the detonating device 300; otherwise, the authorization device 200 sends an information check fail signal to the initiation device 300, and the authorization device ends the authorization supervision process. The detonating device 300 cannot be normally used after receiving the unqualified signal, so that the electronic detonator in the network cannot be detonated, and the illegal blasting is avoided.
(3) The initiation device 300 receives the information verification qualified signal, which indicates that the initiation device 300 is an initiation device authorized to be legally used, so that a series of initiation preparations such as network detection can be carried out on detonators in the initiation network, and after the initiation preparations are completed, the initiation device enters an initiation allowing state, initiation can be further completed, and initiation information is collected to the authorization device.
(5) After receiving the detonation information, the authorization device 200 stores the information and sends the information to the data center 100. The detonation information can comprise information of a detonation network, information of a detonation position, information of time for the detonation device to detonate the electronic detonator, and identity authorization information and image information of an operator who operates the detonation device to complete detonation. Therefore, the data center 100 can collect all relevant information of the blasting, and the data center 100 can check and trace the blasting conveniently.
In the process of checking the information of the detonation system executed by the authorization device 200, the validity of the information of the detonation system is judged according to the blasting authorization information. The blasting authorization information may include one or more of the following: identity coding information of a legal detonating device, geographical position information of a legal blasting area, time information of legal blasting, identity authorization information of a legal operator, a legal detonator identity code, a legal detonator password, a blasting permission delay time limit and the like. The checking content is specifically as follows:
(1) the identity code of the initiation device 300 is checked to determine whether the identity code information matches the identity code information of a legitimate initiation device stored in the authorization device 200. This makes it possible to judge the validity of the use of the detonating device 300 itself, thereby contributing to the assurance of the validity of blasting.
(2) The date and time information of the initiation device 300 when it is powered on is checked to determine whether the date and time information matches the time information of the legitimate blasting stored in the authorization device 200. This ensures the validity of the blasting in time. For example, the blasting regulatory authority may set that blasting is not allowed to be performed on festival days such as national day, spring festival, etc., and if the date and time at the time of starting up is 10 months and 1 day, the result of checking the contents is not qualified, and the blasting device cannot be normally used.
(3) And checking the identity authorization information input by the operator of the detonating device, and judging whether the identity authorization information conforms to the identity authorization information of the legal operator authorized by the data center. The identity authorization information can be verified in a user name password mode in the simplest way. Further, the fingerprint information, iris information, voice information, face information, or the like of the operator can be checked using biometric recognition technology. Therefore, the explosion of an illegal operator by using the detonating device is avoided, and the social safety of the electronic detonator is ensured.
(4) And checking the geographical position information of the blasting place and judging whether the blasting place is in a legal blasting area authorized by the data center. This ensures the legitimacy of the blast site. For example, the blasting monitoring department may set important places such as museums, hospitals, schools, and the like as illegal blasting areas, and if the detonating device is located in these areas, the result of checking the geographical position information is not good, and the detonating device cannot be normally used.
(5) And checking whether the time interval between the acquisition of the blasting position information and the transmission of the blasting system information of the blasting device is within the allowable delay time limit or not, so that the legality of the blasting place can be further ensured. For example, when the location of the blasting site cannot be normally located, the geographical location information may be obtained at other locations within a certain range from the blasting site, and used for checking the geographical location information of the blasting site. In this case, the checking content is designed to limit the distance between the actual blasting site and the site for acquiring the blasting position information, so as to better guarantee the social security of blasting.
(6) The identity codes of the detonators in the network are checked to determine whether they match the legitimate detonator identity codes stored in the authorisation device 200. This ensures the identity legitimacy of the detonator product.
The information checking process of the detonation system can realize the checking of the legitimacy of the detonation device, the legitimacy of the blasting time, the legitimacy of the detonation operator, the identity legitimacy of the detonator product, the legitimacy of the blasting place and the like. The method can realize effective control of time, place and personnel of blasting operation by checking the aspects, and is more beneficial to social safety.

and step C4, ending the detonator password request process.
Corresponding to the flow described in fig. 9, the authorization apparatus 200 executes a detonator password authorization process according to the following steps, and completes authorization of a legal detonator password, as shown in fig. 10: first, the authorization device 200 receives the detonator identification code transmitted from the initiation device 300. Then, the authorization device 200 calls the legal detonator identity code which is stored in the internal nonvolatile memory 203 and authorized by the data center 100, and compares the legal detonator identity code with the detonator identity code sent by the initiation device 300: if the sent identity code of a certain detonator belongs to the identity code of a legal detonator, the detonator is judged to be a legal detonator, the authorization device 200 sets the detonator as a detonator password reading success mark, and sends a legal detonator password corresponding to the identity code of the detonator to the initiation device 300; if the sent identity code of a certain detonator does not belong to the identity code of a legal detonator, the detonator is judged to be an illegal detonator, the authorization device 200 sets the detonator as a detonator password reading error mark, and can send the generated random data to the initiation device 300.

The initiation device 300 executes a detonator password request process, the authorization device 200 executes a detonator password authorization process, and the initiation device and the authorization device are matched with each other to realize the request and authorization of a legal detonator password. The detonating device can send the identity codes of all detonators to the authorization device at one time, can also send the identity codes of a certain number of detonators to the authorization device in batches for multiple times, and can also send the identity codes of the detonators to the authorization device one by one. Similarly, the authorization device may also send the corresponding legal detonator password determined to be legal detonator to the initiation device at one time or in batches for multiple times.
After receiving the legal detonator password sent by the authorization device 200, the initiation device 300 stores the password in the internal cache of the control module 301, and the password corresponds to the identity code one by one. The priming device 300 can continue to perform priming preparation work such as network detection, delay time setting, charging and the like on the detonators in the network, and can execute a detonator password detection process according to the flow shown in fig. 11, and the priming device sends instructions containing legal detonator passwords to each electronic detonator in the priming network one by one, so that the electronic detonator realizes the detection of the detonator passwords. The method comprises the following specific steps:
after receiving the instruction, the electronic detonator firstly judges whether the identity code in the instruction is consistent with the password of the detonator, if so, the electronic detonator continuously judges whether the legal detonator password in the instruction is consistent with the password of the detonator: after comparison, if the detonator password is qualified, namely the password of the detonator is consistent with the legal detonator password in the command, the detonator returns response information to the detonating device; otherwise, the detonator does not return any information, the detonating device adds the information of the detonator into the detonator information list with wrong password detection, and the detonator information with wrong password detection can be displayed to the operator. And after the password of the detonator is detected, the detonating device continues to detect the password of the next detonator.
