Description

FIELD OF THE INVENTION

The present invention relates to the field of production technology of an initiating explosive device, in particular to an electronic detonator coding device used in a detonation network of electronic detonators.

State of the art

In 1980 in Japan, Australia, Europe and some other developed countries and areas began to study the technology of electronic detonator. Significant progress in electronic detonator technology has been made through the rapid development of electronic technology, microelectronics technology and information technology. Applied experiments and market advancement of the electronic detonator have been carried out since the late 90s.

The technical solution of the initiating device of an electronic detonator used with an electronic detonator is disclosed in patent application 200810135028.0. This technical solution revealed the basic design of the initiating device of the electronic detonator and realized the basic functions of the initiating device, such as two-way communication with the electronic detonator and ignition of the electronic detonator.

FIG. 1-1 is a diagram of a detonation network with the aforementioned initiating device of an electronic detonator. The detonation network consists of an initiating device 100, at least one electronic detonator 200 and signal buses 300 that connect the electronic detonator 200 and the initiating device 100, the electronic detonators 200 being connected in parallel between the signal buses 300. The initiating device 100 and the electronic detonator 200 transmit energy and data via signal lines 300, thereby the initiating device can regulate and control the initiation process and the initiation energy and can perform two-way nyuyu connection with an electronic detonator.

The trigger device in the aforementioned technical solution includes a modulation and signal transmission module, which further includes a signal modulation module and a gain module, as shown in FIG. 1-2. The gain module is used to generate the initiating voltage required to charge the storage unit in the electronic detonator. The amplification module amplifies the voltage output by the power source, and then outputs the amplified voltage to the signal buses through the switch of the signal modulation module, charging the initiating storage capacitor in the storage unit in the electronic detonator; the signal modulation module is used to transmit data to all electronic detonators 200, which are connected to the signal lines, and to realize voltage switching, which is output to the signal lines by an initiating device, i.e. switching between the communication voltage and the initiating voltage, and thus the voltage on the signal lines can satisfy different voltage requirements during the process of communication and charging the electronic detonator. This solution implements the regulation and control of the energy needed by the electronic detonator; on the one hand, at the stage of communication, the initiating device controls the voltage on the signal buses so that it becomes the communication voltage, which is lower, ensuring the safety of the detonation network during communication; on the other hand, at the initiation stage, the initiating device switches the voltage on the signal lines to the initiating voltage output by the aforementioned amplification module, which is higher, ensuring that the electronic detonator can receive enough energy for reliable initiation. The signal modulation module also implements data modulation when the initiating device transmits data to the electronic detonator, so that between the initiating device and the electronic detonator communication is carried out through a DC carrier.

In the above-described technical solution, the control module in the initiating device controls the output voltage of the signal modulating module to switch between the communication voltage and the initiating voltage, so that the voltage on the signal buses maintains the communication voltage, which is lower when the initiating device communicates with the electronic detonator, and the voltage on signal buses can be switched from the communication voltage to the initiating voltage, which is higher only when preparing for the initiation vaniyu completed and it is time to charge the storage capacitor initiation, thus providing safety to some degree of the communication process. But since the initiating device 100 itself can output a higher initiating voltage when the logic module malfunctions in the initiating device, or the output signal of the signal modulation module is switched incorrectly, or other problems occur, the initiating voltage is probably output to the signal buses during communication to charge the initiating storage capacitor in the electronic detonator, so that the detonation network can be unexpectedly initiated during implementation communications, leading to hidden dangers when using electronic detonators.

Disclosure of invention

The purpose of the present invention is to eliminate the disadvantages of the above-described prior art and to provide an electronic detonator network device that can realize two-way communication with an electronic detonator and can provide internal security during communication, i.e. an electronic detonator encoder according to the present invention.

The specified technical purpose of the present invention is performed according to the following technical solution.

The electronic detonator encoder has two terminals that are connected to the electronic detonator initiating device, the other two terminals that form the signal lines between the at least one electronic detonator are connected in parallel. The initiating device of the electronic detonator, at least one encoding device of the electronic detonator, which is connected in parallel to the initiating device of the electronic detonator, and one or more electronic detonators, which are connected in parallel to the encoding device of the electronic detonator, form the detonation network of electronic detonators described in the present invention.

The electronic detonator encoder described in the present invention includes a power source, a power source control module, an uplink module, a downlink module, and a control module. The power source control module is used to convert the voltage output by the power source into a communication voltage that is supplied to the downlink module and an operating voltage that is supplied to the uplink module, the downlink module and the control module; the uplink module is used to communicate with the initiating device of the electronic detonator; in the communication step, a downlink module is used to supply the communication voltage to the at least one electronic detonator via the signal lines and to communicate with said at least one electronic detonator at the communication voltage; and in the initiation step, a downlink module is used to supply the initiating voltage outputted by the electronic detonator initiating device to the at least one electronic detonator via signal lines for charging; wherein the control module is used to control the operation of the power source control module, the uplink module and the downlink module.

The above technical solution forms the basic structure of an electronic detonator encoder according to the present invention. Under the control of the control module, the electronic detonator encoder can carry out two-way communication with the initiating device of the electronic detonator via the uplink module, and carry out two-way communication with the electronic detonator through the downlink module. The power supply control module in the electronic detonator encoder can only output the operating voltage and the communication voltage and cannot output the initiating voltage to the electronic detonator network itself, thereby ensuring internal security during the communication phase. During the initiation step, the electronic detonator encoder can output the initiating voltage output by the electronic detonator initiator device to the electronic detonators via the signal lines so that the electronic detonator initiator device can charge the electronic detonators in the detonation network after preparing for detonation. Such a technical solution provides communication among the electronic detonator encoder, the electronic detonator initiator device and all electronic detonators that are connected to the electronic detonator network, and also provides internal security when the electronic detonator encoder communicates with electronic detonators.

The connection of all modules in the above encoder of the electronic detonator can be implemented according to the following solutions.

The power source, the power source control module, the uplink module, the downlink module, and the control module are grounded to the first basic ground. The power source is connected to a power source control module; the control module is connected to the power supply control module, the uplink module and the downlink module. The output terminal of the operating voltage of the power supply control module is connected to an uplink module, a downlink module, and a control module; the output terminal of the communication voltage of the power source control module is connected to the downlink module. The other two outputs of the uplink module are connected respectively to the downlink module and extend beyond the encoding device of the electronic detonator for connection to the initiating device of the electronic detonator. These other two outputs of the downlink module extend beyond the encoding device of the electronic detonator, forming signal buses between which at least one electronic detonator is connected in parallel.

Based on the aforementioned connection solution, the power supply control module may further include a pair of communication voltage sampling terminals, the pair of communication voltage sampling terminals and signal buses being connected one to one. The aforementioned preferred solution makes it possible to sample and adjust the voltage on the signal lines.

The implementation of the invention

The following further describes the technical solutions of the present invention in detail with reference to the accompanying drawings and detailed embodiments.

The present invention provides an electronic detonator encoder 20. Two terminals of the encoder 20 are connected to the initiating device 10 of the electronic detonator, and the other two terminals of the encoder 20 form the signal lines 40 between which at least one electronic detonator 30 is connected in parallel, as shown in FIG. 2. An electronic detonator initiating device 10, at least one electronic detonator encoding device 20, which is connected in parallel with an electronic detonator initiating device 10, and at least one electronic detonator 30, which is connected in parallel with an electronic detonator encoding device 20, form a detonation network of electronic detonators referred to in the present invention.

The electronic detonator encoder 20 referred to in the present invention includes a power source 21, a power source control unit 22, an uplink module 23, a downlink module 24 and a control module 26, as shown in FIG. 3 or 4. The power supply control unit 22 is used to convert the voltage output by the power supply 21 to a communication voltage that is supplied to the downlink module 24 and an operating voltage that is supplied to the uplink module 23, the downlink module 24 and the module 26 management; wherein the uplink module 23 is used to communicate with the initiating device 10 of the electronic detonator; in the communication step, the downlink module 24 is used to supply the communication voltage to the at least one electronic detonator 30 via the signal lines 40 and to communicate with the at least one electronic detonator 30 at the communication voltage; and in the initiation step, the downlink module 24 is used to supply an initiating voltage outputted by the electronic detonator initiating device 10 to the at least one electronic detonator 30 via the charging signal lines 40; and a control unit 26 is used to control the operation of the power supply control unit 22, the uplink module 23 and the downlink module 24.

As shown in FIG. 3, the connection of all modules in the electronic detonator encoder 20 can be described as follows.

The power source 21, the power source control module 22, the uplink module 23, the downlink module 24 and the control module 26 are grounded to the first basic ground 11. The power source 21 is connected to the power source control module 22 and supplies power to the power source control module 22; control module 26 is connected to source control module 22

- 4 025654 power supply, the uplink module 23 and the downlink module 24, and accordingly exchanges data with the above-mentioned modules. The output terminal 1 of the operating voltage of the power source control module is connected to the uplink module 23, the downlink module 24 and the control module 26 and supplies the operating voltage to the above-mentioned modules; the output terminal 2 of the communication voltage of the power supply control unit 22 is connected to the downlink module 24 and supplies the communication voltage to the downlink module 24. The other two pins 70 and 70 'of the uplink module are connected respectively to the downlink module 24 and extend beyond the electronic detonator encoder 20 to connect to the electronic detonator initiating device 10. The other two outputs of the downlink module 24 extend beyond the electronic detonator encoder 20, forming signal lines 40. One or more electronic detonators 30 are connected in parallel with the signal lines.

The above technical solution forms the basic structure of the electronic detonator encoder 20 according to the present invention. Under the control of the control module 26, the electronic detonator encoder 20 can communicate bilaterally with the initiating device 10 of the electronic detonator through the uplink module 23 and communicate bilaterally with the electronic detonators 30 through the downlink module 24. The electronic detonator encoder 20 cannot output the initiating voltage to the electronic detonator network, so that the electronic detonator initiator 10 is connected directly to the downlink module 24 for charging the electronic detonator 30 in the detonator network after preparation for initiation and for sending initiation instructions for controlling the electronic detonator detonator 30. This design implements communication among the encoding device 20 of the electronic detonator, the initiating device 10 electron nnogo detonator and electronic detonators in a network of electronic detonators, as well as internal security, when the encoder 20 electronic detonator is in communication with a network of electronic detonators.

In practical applications, to make it more convenient and humane to use the electronic detonator encoder 20, the electronic detonator encoder 20 may also include a human-machine interface module 25, as shown in FIG. 4, wherein the human-machine interface module 25 is used to exchange information between the user and the electronic detonator encoder 20. For example, a human machine interface module 25 may receive instructions from a user and transmit instructions to a control module 26 to control other modules to perform appropriate operations. The man-machine interface module 25 can also inform the user of the results of the operation of the electronic detonator encoder 20 in the form of images, sounds, etc. The human machine interface module 25 may be some common device, such as a keyboard and display. The presence of the module 25 of the interface man-machine as part of the encoding device of the electronic detonator may depend on actual requirements.

As follows from the embodiment shown in FIG. 3, the power supply control module may further include a pair of communication voltage sampling terminals 3 and 3 ′, the pair of communication voltage sampling terminals 3 and 3 ′ and signal buses 40 being connected one to one. Such a preferred embodiment makes it possible to sample and adjust the voltage on the signal lines.

There are many preferred embodiments in all aspects of the technical solution of the present invention, which can be described in more detail as follows.

According to a first aspect corresponding to the embodiment shown in FIG. 4, in order to sample the voltage of the signal lines 40, the power supply control unit 22 may include a voltage conversion unit 221 and an L / O converter 222, as shown in FIG. 5. The voltage conversion module 221 and the L / C converter 222 are grounded to the first basic ground 11; the voltage conversion module 221 has the other two terminals, one of which is connected to the power supply 21, and the other extends beyond the power supply control module 22, forming the output voltage output 2 of the communication module 22 of the power supply control. The other terminal of the voltage conversion unit 221 is connected to the A / O converter 222 for supplying power to it and also extends beyond the limits of the power supply control unit 22, forming the output voltage output 1 of the power supply control unit 22. The other terminal L / S of the converter 222 is connected to the control unit 26 to communicate with the control unit 26. The other two terminals of the L / S converter 222 extend beyond the power supply control unit 22, forming the connection voltage sampling conclusions 3.

The aforementioned power supply control module 22 supplies the operating voltage needed by the other module in the electronic detonator encoder 20 for normal operation, and the communication voltage to the signal lines 40 when communicating with the electronic detonator 30, and the power supply control module 22 also controls the value of the communication voltage, which ensures that the value of the communication voltage is much less than the value of the allowable voltage of the electronic detonator 30, i.e. the communication voltage value is less than the lowest voltage value,

- 5,025,654 which is required to initiate the electronic detonator 30. Thus, it is useful for the safety of communication with the electronic detonator 30 and the operation of the electronic detonator 30.

In addition to the embodiment shown in FIG. 5, the power supply control module 22 can also be implemented in accordance with the technical solution disclosed in patent application 200810135028.0, as shown in FIG. 6. Compared to the embodiment shown in FIG. 5, power supply control unit 22 in FIG. 6 further includes an Ό / Ά converter 223. The Ό / Ά converter 223 is connected to the voltage conversion module 221, and an operating voltage is supplied to it by the voltage conversion module 221; The Ό / Ά converter 223 is connected to the voltage conversion unit 221 in a different way by transmitting a communication voltage control signal to the voltage conversion unit 221. The other terminal Ό / Ά of the converter 223 is grounded to the first base ground 11, while the other terminal is connected to the control unit 26. A Ό / Ά converter 223 is used to receive the result of the information processing of the voltage signal on the signal lines 40 processed by the control unit 26, the processing result being converted by the Ό / Ά converter 223 into an analog voltage signal, which is said communication voltage adjustment signal supplied to the conversion module 221 voltage, thereby realizing the function of adjusting the communication voltage output to the signal bus 40.

The power supply control module 22 in both embodiments shown in FIG. 5 and 6, has a Ά / Ό converter 222. In order to simplify the design, it may not be necessary to sample and control the voltage on the signal lines 40, and thus the power supply control unit 22 can consist only of the voltage conversion unit 221. The voltage conversion unit 221 converts the electrical energy input by the power source 21 into a communication voltage and an operating voltage, respectively, which are output outside the power source control unit 22. This embodiment corresponds to the embodiment shown in FIG. 3.

According to a second aspect, the aforementioned control unit 26 may include an SRI 262 and a wave transceiver module 261. The wave transceiver module 261 consists of an initiator device wave transform module 2630 and an electronic detonator wave transform module 2610, as shown in FIG. 7. SRI 262, the wave conversion module 2630 of the initiating device and the wave conversion module 2610 of the electronic detonator are connected to the output terminal 1 of the operating voltage, taking the operating voltage supplied by the power supply control module 22. The initiator device's wave conversion module 2630 and the electronic detonator wave conversion module 2610 are respectively connected to the SRI 262 for two-way communication with the SRI. SRI 262, initiating device wave conversion module 2630 and electronic detonator wave conversion module 2610 are also grounded to the first basic ground 11. The other output of the initiating device wave conversion module 2630 continues beyond the transceiver wave conversion module 261, forming an uplink terminal 8 of the control unit 26, wherein the uplink terminal is connected to the uplink module 23. The other terminal of the electronic detonator wave conversion module 2610 extends beyond the transceiver module 261 of the wave conversion, forming a downlink terminal 9 of the control module 26, the downlink terminal being connected to the downlink module 24. The above uplink terminal 8 may accurately represent the uplink output terminal 61 and the upstream input terminal 62 of the control unit 26 in the embodiment shown in FIG. 12, and the downlink terminal 9 may accurately represent the downlink output terminal 71 and the downstream input terminal 72 of the control unit 26 in the embodiment shown in FIG. 8 or 11.

CPI 262 controls the operation of the initiator device’s wave conversion module 2630 for two-way communication with the electronic detonator initiator device 10 and controls the operation of the electronic detonator wave converter module 2610 for two-way communication with the electronic detonator 30. To exchange data with the electronic detonator 30, for example, on the one hand, the electronic detonator wave conversion module 2610 receives data from the downlink module 24, converts the data to a specific nd format which can be identified by the MIS 262, and then transmits the converted data to the MIS 262 for further processing; on the other hand, the electronic detonator wave conversion module 2610 receives data from the SRI 262 and converts the data to a specific format to transmit to the electronic detonator 30 through the downlink module 24.

The above electronic detonator wave conversion module 2610 may include a data interface circuit 2611, a data encoding circuit 2612, a data decoding circuit 2613, and a sampling circuit 2614, as shown in FIG. 8. The data interface circuit 2611 provides two-way communication with the SRI 262. The SRI 262 sends the data to be sent to the data encoding circuit 2612 via the data interface circuit 2611, and the data encoding circuit 2612 encodes the data to be sent, and then outputs the encoded data to the downstream communication module 24; the data decoding circuit 2613 receives and decodes the data to be received sent by the downlink module 24, and then outputs the decoded data to the sampling circuit 2614 for sampling, and the sampling circuit 2614 then sends the sampling data to CPi 262 via the data interface circuit 2611. Such a solution implements two-way data exchange between the downlink module 24 and the control module 26.

An embodiment may be further performed based on the embodiment shown in FIG. 8. A frequency measurement circuit 2621 may be added between the downlink input terminal 72 and the data interface circuit 2611, as shown in FIG. 11, and thereby the electronic detonator wave conversion module 2610 can measure the frequency of the signal received by the downlink module 24. Since to some extent the integrated circuit manufacturing technology itself leads to a certain frequency shift of the generator in the integrated circuit, the frequency measurement circuit 2621 in the encoder 20 can be used to measure the clock frequency of the generator in the electronic detonator 30 so that the delay time can be calibrated in the encoder 20 electronic detonator. This design is useful for improving the accuracy of the delay time in the detonation network of electronic detonators.

The data encoding circuit 2612 in both of FIGS. 8 and 11 may modulate the frequency for encoding data, as shown in the wave diagram of FIG. 35. As shown in FIG. 35, when transmitting instructions, the data encoding circuit 2612 may first send synchronous headers for analysis, the sum of which is a predetermined number m, before sending the service control word. The electronic detonator 30 will start the counter in an integrated circuit to count the number of synchronous headers for analysis after receiving the boundary signal of the synchronous headers for analysis. Then, the SRI in the integrated circuit will calculate the clock number of the CS generator, which should be used by the serial communication interface and suitably correspond to the predetermined communication data rate and the predetermined sampling phase, thereby adjusting the data reception time and the counting period of the electronic detonator 30. Such a solution can ensure that the control integrated circuit of the electronic detonator with the KS generator can still reliably receive control instructions sent to the encoder the electronic detonator device 20, even if problems such as temperature fluctuation, clock shift, and parameter changes still exist in the KS generator.

The data decoding circuit 2613 in the electronic detonator wave conversion module 2610 may further include a signal synthesis circuit 2617 and two edge triggers 2615 and 2616, as shown in FIG. 9. The input terminals of the two edge triggers 2615 and 2616 extend respectively outside the data decoding circuit 2613, connecting to the downlink module 24; the output terminals of the two edge triggers 2615 and 2616 are connected respectively to a signal synthesis circuit 2617; and another output of the signal synthesis circuit 2617 extends beyond the data decoding circuit 2613 and is connected to the sampling circuit 2614. The two edge triggers 2615 and 2616 are used respectively to sample the two pulse signals sent by the downlink module 24, and after processing the signal synthesis circuit 2617, the two pulse signals are converted into a rectangular signal, which is output to the sampling circuit 2614, and then the sampled rectangular signal is sent to the SRI 262 via a data interface circuit 2611, thereby decoding data sent to the encoder 20 by an electronic detonator 30. FIG. 36 shows a process of how the two pulse signals are synthesized into a rectangular signal: the signal synthesis circuit 2617 respectively receives two pulse signals sent by the edge trigger 2615 and the edge trigger 2616, and the signal synthesis circuit converts between a high level and a low level, each time a leading edge signal, thereby realizing the synthesis of two pulsed signals.

The sampling circuit 2614 of the electronic detonator wave conversion module 2610 may include a sampling and counting module 2619 and a storage and transmission module 2620, as shown in FIG. 10. After the sampling circuit 2614 receives the signal wave sent by the data decoding circuit 2613, the sampling and counting unit 2619 starts sampling and counting the midpoint of each signal pulse, the storage and transmitting unit 2620 sends the sampled data to the data interface circuit 2611, and then the sampled data is sent to the SRI 262 via a data interface circuit 2611. Sampling and counting module 2619 may be a counter as an embodiment, and storage and transmission module 2620 may be a shift register as an embodiment.

The aforementioned initiating device wave transform module 2630 may include a data encoding and transmitting circuit 2631, a data decoding and receiving circuit 2632, and a data interface 2633, as shown in FIG. 12. The SRI 262 sends the data to be sent to the data encoding and transmission circuit 2631 via the data interface 2633, the data encoding and transmission circuit 2631 encodes the data to be sent, and then outputs the encoded data to the uplink module 23; a data decoding and receiving circuit 2632 receives and decodes data sent by the uplink module 23, and then outputs the decoded data to the SRI

- 7 025654

262 via the data interface 2633, thereby realizing two-way data exchange between the uplink module 23 and the control module 26. When encoding and transmitting data, the input and output wave of the initiator device wave conversion module 2630 may look like that shown in FIG. 37; when decoding and receiving data, the input and output wave of the wave conversion module 2630 of the initiating device may look like that shown in FIG. 38.

The data interface 2633 of the initiator wave transform module 2630 may be a serial interface such as K8485, K8232, etc. The data encoding and transmission circuit 2631 in the wave conversion module 2630 of the initiating device can modulate the frequency for encoding the data. The data decoding and receiving circuit 2632 may further include a sampling circuit 2634, an amplifier 2635, a comparator 2636, and a signal sampling circuit 2637, as shown in FIG. 13.

2) a single signal control circuit 2321 is driven by an uplink power supply circuit 230. The single-signal control circuit 2321 is directly connected to the communication lines 80 of the initiating device 10 for transmitting signals that are sent by the initiating device 10 to the encoding device 20, to the primary winding 501 of the transformer isolated circuit 2322, thereby realizing the transmission of signals.
