11 leather sales Conventional blasting systems include a series of explosive charges that are remotely commanded. Detonated by a detonator connected to a source. Set to detonate in the latter half of the demolition work. To prevent the wire-connected detonator equipment from being damaged by the initial detonation, Recent improvements made to the system include electronic delays (over older, less accurate pyrotechnics). (alternatives to technical delays) and the ability to program such delays in the field. This includes the ability to West German Publication No. 3301251 states that these systems Provides an example of the flexibility that comes with ability.

Australian Patent Application No. PH1255, which was recently filed concurrently by the inventor, is It relates to a detonator device, the detonator is provided with a condition setting means, and the means is provided with a condition setting means. Switching the condition setting means from the “normal” state (incapable of being fired) to the “armed” state Prior to ignition, the fuse head conductor must be electrically conductive to carry any voltage or current that could ignite the detonator. It is a means of making the transfer impossible. This is a small amount that was not present in the original detonator device. This provides an element of safety that is not required.

Hikarihada@Hadajo The inventor has discovered that by using a detonator as described above with a specific actuation system, , we have found that it is possible to maximize this safety factor. As a result, the present invention The present invention provides an actuator for a detonator. The present invention The feature is that the controller is equipped with a control circuit, and the control circuit is connected to the controller from the control device. In response to an input signal applied to an input of the control circuit, the control circuit becomes operational. (1) by receiving at least one predetermined input signal; emits an output arming signal that is applied to the detonator in use, and causes the detonator to be actuated. and (2) a predetermined delay associated with the predetermined input signal. After the extended time period, issuing an output activation signal to be applied to the detonator is performed.

The "actuator" receives a signal from the control device and activates the detonator. means a device whose function is to Actuators of the type used in the invention The type of detonator to which the data is associated must be armed before it can detonate. It is of the type that does not exist. For particularly suitable types, the inventor may apply at the same time. Australian Patent Application No. PH1255. However, according to the present invention The actuator, for example, can actuate the detonator in such a way that only the actuation signal is transmitted to the detonator. By connecting it to a detonator, it can be used in association with a conventional detonator. It is possible to The word "associate" here refers to the detonator and actuator. the actuator is connected in such a way that the signal is passed from the actuator to the detonator. means to be This can be done, for example, by wiring two elements together. or by integrating the actuator into the detonator device. It is possible to accomplish this.

However, in the preferred embodiment, the actuator and detonator are mounted on their respective modules. housed in a dual-style housing, each can be easily tied off before being inserted into the blast hole. be combined and become one.

In this case, all electrical connections are properly connected due to the combination of modular housings. Established.

The actuator used in the present invention is designed to reduce the delay time, which is particularly important in large-scale commercial demolition. Incorporate a time device. The specified length of the delay time is set in the actuator during the manufacturing process. However, the delay time should preferably be programmable. stomach. This gives the system considerable flexibility. Therefore, the actuator The equipment shall be electronically programmable before being inserted into the blast hole. Furthermore, lightning Before the tube device is inserted into the blast hole, the actuator is Greater flexibility can be provided if the data can be programmed. that Detonation pattern by the time of sending the input armament and input actuation signals. can be changed at will and completely safely.

Electronic circuitry within the actuator stores delay information and outputs one or more signals from the controller. Act by several reasonable signals, output armament and output actuation signals, selected Occurs every delay time. Preferably, the circuit is a microcomputer with storage. the storage device stores at least one armed code and one activation code. and preferably also the selected delay time. Microco The computer analyzes the input signal and converts it into a predetermined or predetermined signal. When a plurality of predetermined signals are confirmed, output weapons and activation that respond appropriately Allow a signal to be generated.

The type of signal received by the actuator may be any known to the art. It may be any suitable signal. It can be a single signal, for example, or an actuator. The actuator circuit is configured such that the signal is stored in the actuator circuit and activated. voltage exceeding the code, refer to it's predetermined delay time, and arm your bell It is. Other signals include one arming code and one activation code. for example, a stepped voltage signal, in which the rising edge The rising edge may be provided with an activation signal. However, arming and activation signals It is desirable that both of them be digital signals. Inadvertent or unauthorized ignition can thereby be almost completely eliminated.

The type of signal sent to the detonator by the actuator is said to activate the detonator. It may be any convenient signal suitable for the purpose. For a conventional detonator, it is A simple device suitable for producing the ignition of a flash mixture charge and subsequent detonation of the detonator. Can be voltage or current, but the signal comprises a multi-bit digital code It is preferred that such a signaling system When used with a suitable detonator, as described in patent application no. PH1255, the The system offers a high degree of security and safety not available with known explosive systems. Allow for totality.

Power to drive the actuator and the detonator itself may be provided by any convenient means. can also be supplied, but the means is designed to detonate later in the series of detonations. A set detonator malfunctions due to damage to the wiring to the detonator from a premature explosion. This is consistent with the fact that it must be easy to Therefore, the weapon of the detonator The equipment and actuation power supply should be in close proximity to the actuator, and Preferably housed within or connected to the actuator housing. It is desirable to either make it possible to do so.

The power source may be a battery or, preferably, a capacitor charged by a signal from the ground. A temporary power supply is sufficient. In particularly preferred embodiments of the invention, the capacitor is separate. The detonator unit and actuator unit are housed in a housing that can be attached to the unit. and all these units are made up of several modular units tied together. It is molded into an integrated unit with appropriate internal wiring and connections in a manner that allows for

The actuator receives signals for itself from the ground controller. this The control device may be a box-shaped remote ignition device as is well known in the art. deer However, when the actuator of the invention is used with selected control devices, the result is provides a detonator actuation system with significant flexibility and safety.

Therefore, the inventor also provides a detonator actuation system with (1) a detonator device having an explosive charge; an associated actuator as described above; and (2) an actuator. A control device is provided to control the operation of the detonator by means of sending a signal to the detonator.

The system further includes a microcomputer in which the control device has the storage device. In that case, the computer is configured from an armed code. generation of the device signal and radiation to the actuator when activated by the user. Therefore, the occurrence of the armed key and the activation signal derived from the activation code. , and has an actuation key that causes the radiation to be caused by actuation by a user; The computer determines that the activation key is activated within a predetermined time after activation of the armed key. actuator, otherwise no actuation signal is transmitted to the actuator. It's starting to look ugly.

The invention further provides a control device suitable for use in the detonator actuation system described above, and and a method of detonation using the system.

A control device working in conjunction with an actuator is adapted to control multiple detonators. There is. The control device includes at least an arming and activation code and an arming and activation key. Equipped with a microcomputer with act to occur and send a signal to the actuator. The microco The computer must be activated within a predetermined time after the armed key is activated. otherwise the activation signal will not be transmitted. This special The length adds a useful additional safety margin to an already fully complete system. Ru.

Preferably, the storage device further stores a reset code and the microcomputer If the activation key is not activated within a predetermined time after activation of the armed key, , until the sequence of receiving the reset code signal, it will not be activated to detonate. be able to do so. The actuator must be properly rotated to allow this reset function. Needless to say, we must have a road.

In a further preferred embodiment, the delay time of the actuator unit is controlled by the control device. It is possible to be more calibrated. This creates an actuator that responds to a calibration signal. This is achieved by having a calibration key, and the control device's microcomputer Set to issue an output calibration signal in response to actuation or programmed instruction has been done. In this case, the timing means in the control circuit of the actuator unit is activated for a period of time until it is terminated by a control signal from the control device; The output of the timing means is stored in a control circuit, in which case The delay time provided can be calibrated on a time basis with respect to the control device. . Control the calibration function so that it is activated automatically when the armed key is activated. It is possible to incorporate it into the control device.

As mentioned above, in addition to calibrating the delay time for activating the detonator, It is also possible to program the delay time from This is a properly equipped control It can be done from the device. A further notable advantage of the present invention is that the calibration is This can be done just seconds before detonation, and the calibration signal can be It is possible to make it a part of the

This allows the use of low-cost elements and reduces costs considerably.

In a preferred embodiment of the invention, the actuator includes a transducer unit. the transducer unit can be fitted with an actuator; can be coupled to the ether so that all electrical connections are made properly. This technology As is well known in the art, transducer units are an electronic device that responds to a physical parameter (e.g., pressure or temperature); it produces a corresponding conditioning signal, which conditioning signal is e.g. sent to a device that changes its behavior depending on the location or parameters . In this case, the information from the transducer is used to change the actuator calibration. The changes are communicated back to the ground controller, which then It is possible to receive signals. The actuator thus “talks back” to the control device. ”, which allows for closer control over the entire blasting operation. Make it.

In some embodiments, the control device has a direct connection to the control circuit of the actuator unit. Equipped with a connector that allows connection, and data stored in the actuator unit. Be able to read the data. The data may include, for example, the user's identification code, specific The code number assigned to the detonator and the delay time programmed into the detonator control circuit. Consists of. The control device includes a liquid crystal display or visual display that displays the information to the user. It is possible to provide a display device such as a digital display device. Another embodiment of the invention , the detonator is capable of receiving a control signal that prevents its operation, and the control device is , continuous control signals that prevent any inadvertent or accidental ignition. It is equipped with a circuit that sends a current to the detonator. Appropriate circuits should be reviewed at the same time. It is written in the Stralia patent application form P old No. 258.

The housing 44 includes transverse partitions 46 and 4. 8, and the transverse partition is mounted so as to press against the housing 44. No. One chamber 50 is formed between partitions 46 and 48, and a second chamber 52 is formed between partitions 46 and 48. 46 and a closed end wall 54 of the housing. Two fuse head leads The bodies 56 and 58 are placed in the second chamber while being separated by the insulating block 60. It extends to Conductors 56 and 58 are fused to a flash mixture spot charge 64. It is coupled to enable element 62 . The remainder of the second chamber 52 is filled with explosive material. Filled or partially filled with base fill 66.

Conductors 56 and 58 have insulated portions 68 and 70, which insulate portions 68 and 70. It passes through the open lower portion 2 of the partition 46 and extends into the first chamber 50 .

Inside the first chamber 50 is a circuit board 74, which includes an electronic circuit board 74. and/or electrical components are attached. The substrate 74 includes the partition 46 and It is supported by tabs 76 and 78 which are pressed out from 48. Partition 48 It also supports a multi-board connector 80 for a busbar 82.

Busbar 82 has multiple conductors, thereby providing electrical interconnection between the various modular units. Enables binding. However, in order to make each unit work, all of the multiplex lines are required. Not only in cases where it is necessary.

FIG. 5 schematically shows the various lines in the busbar 82 to explain their arrangement. This is a diagram. In this case, 11 lines 84°86, 88, 90, 92, 9 There are 4, 96, 98, 100, 102, and 104, and some of them are The cap is necessary for operating the circuit on the board 74 of the detonator unit 22.

FIG. 6 schematically shows the circuit 106 mounted on the board 74 of the detonator unit 22. to show. Circuit 106 includes a circuit that enables connection to selected lines within bus bar 82. A connector 108 is provided.

In this arrangement diagram, line 84 is the power line and line 86 is the ground line for the power supply. . Wires 94 and 96 carry a high current capable of melting the fusible element 62 at a reasonable time. transport. Line 104 carries the clock pulse, in which case line 102 carrying a J signal, the "arm" signal placing the detonator unit 22 in an "armed" state; The detonator unit thereby receives reasonable drive current on lines 94 and 96. and can be operated by. In the array diagram, lines 94, 96, 1 The signals and currents on 02 and 104 are pulled from actuator unit 24. It's coming out. Power lines 84 and 86 receive power from battery unit 38 are combined for.

Circuit 106 is typically connected to drive coil 112 and conductors 113 and 115. includes a relay 110 having a closed contact 114 and a normally open contact 116. The conductors 113 and 115 are connected to the wires 94 and 96 via the connector 108. It is connected. Normally open contacts 114 are connected to aluminum by conductor 117. connected to the housing 44, whereby both sides of the fusible element 62 are directly connected to the housing 44. is shorted to ging. This is an important safety factor, as the detonator unit 22 -110 is not activated. This is the stray current , or due to involuntary actuation due to radio frequency electromagnetic radiation, the detonator unit 2 Protect 2. In the illustrated arrangement, relay 110 provides a signal for activation of the detonator unit. It does not work until just before the signal is delivered to lines 94 and 96. Therefore, the sequence fuse head conductors 56 and 5 until just before detonator unit 22 is activated. 8 receives an electromagnetic or electrostatic charge that could inadvertently melt the meltable element 62. It has the advantage of not being able to be used.

The operating coil 112 of the relay is connected to a logic circuit 118, which is connected to wire 10. 2 and 104 are received. In the preferred arrangement, circuit 118 connects line 1 Receives an “arm” signal consisting of two parts of 4-bit code on 02 and activates the relay. An output must be made on line 120 to activate it.

The circuit 118 has eight output terminals Q0 to Q7. 1 741648 bit A shift register 122 is provided. The circuit further includes four exclusive OR gates 1 24, 126, 128, and 130, each of these gates has a girder. The non-output terminal of the feed register 122 is connected to the four input AND gates 132. The output terminal of the AND gate is connected to the input of three high current AND gates 134. Connected to one of the terminals. The circuit further includes four input HAND gates 136. The NAND gate is connected to the first four output terminals of the register 122, and A second NAND gate 138 is connected to the second four output terminals of register 122. Ru. The output terminals of NAND gates 136 and 138 are connected to the remaining output terminals of AND gate 134. They are respectively connected to two input terminals. Connected to output terminals QO to Q7 of register 122. The connected gate configuration ensures that only the selected 8-bit signal on line 102 is connected to the relay. The configuration is such that a signal for activating the switch is sent to the output terminal 120. Ru. The signal is such that the first 4 bits are exactly the complement of the second 4 bits, and Unless it is a signal that the first 4 bits are not all 1 or all O. No. The latter requirement is important in practice, as failures in circuit 118 If a high level signal or short circuit is applied to line 102, the condition indicates a faulty circuit. Prevent movement. The circuit 106 described above is taken as an example and there are many alternatives. It is obvious that the circuit can be used. If at any time, please use the “arm” signal. When a high signal enters line 102, output line 120 goes low, disabling relay 110. Activate. The control device 14 can generate a reset signal for this purpose. It is Noh. In either case, logic circuit 118 may be configured to receive signals other than the "arm" signal. If any signal is received, the output 120 is set to low level. Valid “A” An example of a "home" signal is as follows:

Additionally, circuit 106 may be integrally integrated, except for relays, if necessary. Is possible.

FIG. 7 shows an alternative circuit 140 for the condition setting means. Bus bar 82 to connector 1 The input terminal to 08 is the same as that for circuit 106, and also for logic circuit 118. , as in the case of circuit 106. However, regarding the array, the logic circuit 118 line 94 until immediately before actuation by receiving a precisely coded signal for and 96 to ensure no electrical connection to the fusible element 62. It uses an alternate arrangement. In that arrangement, the circuit includes two solid state relays 142 and and 144.

The relay includes permanently grounded electrodes 146 and 148, respectively. Applicable The relay also has electrodes 150 and 152, each of which has a meltable element. Connect to the insulated portions of conductors 56 and 58 that lead to element 62. The relay has an electrode 146 and 150 and electrodes 148 and 152 are internally connected and thereby conductive. Both bodies 56 and 58 are grounded and connected to housing 44. ing. The relays also include electrodes 154 and 156, respectively. The electrodes connect to lines 94 and 96 via conductors 113 and 115. The relay Upon receiving a trigger signal on trigger electrodes 158 and 160, the internal connections change. Shi-den 8i! 150 and 154 and electrodes 152 and 156 are internally connected.

In this case, conductors 56 and 58 are no longer grounded and lines 94 and 96 The fusible element 62 is then electrically connected to the meltable element 62, and the fusible element 62 is ready for operation. From logic circuit 118 The triggering of the relay by the output line 120 coming out will be explained below. .

Output line 120 from circuit 118 connects to the input terminal of amplifier 162 and The device passes through a resistor 172 and connects three fusible links 166, 168 and 170. It connects to a branch point 164. The circuit includes an AND gate 174, one of which has an input terminal connected to output line 120 and another input terminal of it connects to branch point 164. Continue. The output terminal from the game) 174 is connected to the trigger terminal 158 of the relay and Connect to 160. The array is an input terminal to gate 174 during normal operation. are both low levels, which will not trigger the relay. but, When a correctly encoded signal comes on line 102, the signal on output line 120 of circuit 118 is The level is high enough so that the meltable links 166, 188 , and 170 destroy. When all links are destroyed, branch point 164 becomes high. level and therefore gate 174 also goes high and the relay is triggered. . This couples conductors 56 and 58 to wires 94 and 96 and operational readiness is established. It will be done. Until logic circuit 118 detects a correctly encoded signal, Element 62 is protected by fusible links 166, 168, and 170. The points to be evaluated will be evaluated. The arrangement is such that conductors 56 and This prevents unintended charges or currents from developing in and 58.

The multivibrator circuit 214 is powered by the central processing unit 208. Guaranteed to be reset up. run by microcomputer The first programming function provided is to confirm that the detonator unit 22 is now safe. It's a guarantee. This sends eight consecutive zeros from bin 32 of input/output device 210. and the pin 32 is connected to the line 102. This is the detonator unit A register 122 in unit 22 is initialized to zero, thus detonator unit 2 2 ensures that it cannot be activated due to the arrangement of logic circuit 118. Ru.

If the signal If not a "calibrate" command, the program returns and waits for a valid command. .

Whenever a false signal is received, the program returns to the start.

When the controller 14 transmits a "calibrate" command, the command is recognized by the program. The program is then executed by the central processing unit 2, as shown in step 230 of FIG. The timing of the pulses derived from the crystal clock 228 connected to bins 1 and 2 of 08 Start calibration calibration. The program then stops pulse counting and records the counted pulses. A command signal is awaited on line 88 to record the number of pulses. This is the 10th This is shown in step 232 of the figure.

These program steps control the clock rate of central processing unit 208. be accurately correlated with the signal generated by device 14 and transmitted on line 88. and thereby allows the actuator unit 24 to communicate with the control device 14. , it is possible to have a very precisely calibrated relative relationship. .

The control device 14 has a precisely determined time reference, by means of which the actuator The multiplicity of the actuator 24 can be adjusted to accurately calibrate the multiplicity of the actuator 24. The editor does not have exactly selected elements and therefore does not necessarily have a very precise They do not necessarily have a knowledge time standard.

Moreover, the calibration procedure can be carried out just before signaling the activation of the detonator unit. This reduces the possibility of malfunctions caused by changes in conditions such as temperature and pressure. minimize potential.

In the preferred arrangement, the signal on line 88 that stops the timer is effectively Another "blow up" code generated by 4, the "blow up" code is Selected so that it can be confirmed for a particular explosion, e.g. identification, date, continuation explosion number, etc. The question box 234 in FIG. Showing the programming steps. If the next signal received on line 88 is the correct "blast" If not, the program returns to the start and the detonator unit is not armed. recalibration is required.

On the other hand, if the "blow up" code is correct, the program then activates actuator 2. 4, the exact delay time required before sending the detonator unit 22 detonation activation signal. Calculate. This is illustrated by programming step 236 in FIG. for example, Actuator 24 triggers an explosion that begins upon generation of a "boom" command by controller 14. After a precisely predetermined delay time of 10 milliseconds from the start of the failure sequence. , it is possible to be required to operate the detonator unit 22 accurately. specific Information regarding the delay time is stored in the electrically programmable ROM 212. , the program is thereby required to provide accurate delay times. Because of the computer 206, it is possible to calculate the exact number of lock cycles. Ru. On the other hand, the calibration information is stored in a random access storage device in the input/output device 210. has been done.

Following this step, the actuator unit 24 directs the control device 14 to The control device is working properly and the actuator unit is receiving a valid signal. You can signal that. The return signal to the control device 14 is sent to the central processing unit 20. It is conveyed by a line 90 connected to the bins 4 of 8. This is the step in Figure 10. 238. Arming the detonator unit 22 is shown in step 240 and its In this case, the arm j signal is generated on bins 31 and 32 of input/output device 210.

The program is then configured to set a predetermined time, e.g. 5 seconds. During this period, a signal from the control device 14, which is a signal for operating the detonator unit 22, is transmitted. A "BOOM" command must be received on line 88. If within the 5 second period If no “boom” command signal is received, the program returns to start and detonator The unit must be prepared by going through the recalibration procedure again before it can be put into operation. . These program steps are 242, 244, and 246 in FIG. The "boom" command signal on line 88 shown in Figure 2 is a correct 8-bit pattern signal. Must. Otherwise, the program will ask questions indicated in question box 248. As shown, return to the start again. If the “boom” command is correct, the program The required delay time information is input and output as shown in system steps 250 and 252. is retrieved from random access storage in power device 210 and the delay time is will be put on standby. At the end of the delay time, the signal is passed to the input/output device 210, and the signal is passed to the input/output device 210. Output bins 2 and 3° will be at high level. These output bins are current driver 2 54 and 256 to lines 96 and 94, the current driver , melts the fusible element 62 and ignites the flash drug 64, thereby igniting the detonator unit. The fuse head operating current required to operate the fuse head 22, e.g. 1.5 amps. Supply a pair. This is shown in program step 258. Detonator unit 22 Since the detonator assembly 6 is destroyed as well as actuated, the control device 14 controls the detonator assembly 6. The success of a yellowtail operation is known by the silence of the detonator assembly. But if it malfunctions , the program includes a question box 260, which indicates that the central processing unit is still functioning, and if so, that information is passed to line 9. 0 and further transmitted to the control device 14. The program thereby Return to the start, where the detonator unit is safe again. This is a program step. 260 and 262.
