Description
Technical field
The present invention relates to priming system and control technology field thereof, relate in particular to wireless detonator, demolition set and blasting method.
Background technology
In mining processes, carry out effective rock fragmentation by the blasting charge, need quite high technology and special knowledge.In most of minings, in stone, calculate good position and place the blasting charge of right quantity.The blasting charge is ignited through detonator predetermined time delay, meets the requirements of the cracked pattern of explosion and stone thus.Usually, signal is sent to detonator by detonate electric wire (LEDC) or detonator of the low energy of non-electric system.The electronics line also can send signal to electric detonator in addition.Recently, electric detonator allows to use 1ms or programmable delay time still less.
Determine the position that the blasting scheme and the blasting charge are laid, often be to use a large amount of labours, highly rely on blast operations personnel's accurate and conscientious degree.The blast operations personnel must place the blasting charge accurately, for example in the boring of stone, determine that detonator contacts well with the blasting charge.Importantly, the blast operations personnel must confirm that the communication of detonator and trigger is good, ignite each detonator and can ignite each blasting charge thereby trigger can send ignition signal.
Can directly carry out telecommunications between trigger and the detonator in the electronics fuzing system, armament, perhaps allow to use the signal of more complexity to send.For example, sort signal sends may comprise ARM to be sent instructions, remove DISARM to be sent instructions, and the instruction of the delay time of detonator being carried out remote programmable.In addition, as security feature, detonator can store the ignition code, has only the ignition code that receives from the trigger Shi Caihui that matches to treat and send out and ignition signal responds.
In order to respond described command signal, the electric detonator system also can comprise the programmable circuit that can receive, store and handle received signal.Yet this programmable circuit may cause safety problem.For example, to cause the detonator primary charge to be misquoted quick-fried for the power supply of the programmable circuit detonation circuit that can influence detonator.
The receiving system of detonator control signal and method have improved to some extent and have misquoted quick-fried possibility with reduction now, thereby improve the security of blasting scheme.The development of wireless detonator and corresponding detonator system has also improved shotfiring safety.The personnel that are familiar with this technology recognize the great potential of wireless detonator system to the raising of explosion site safety.By avoiding the physical connection (as the electronics line, detonator, LEDC, perhaps optical cable) between the detonator, the unsafe factor of on-the-spot other assembly of explosion also decreases.In the wired detonator system of tradition, need very skilled and careful the connecting up of operator, also will carefulness very determine that the line that causes trigger from the blasting charge (with the detonator that is connected) does not open circuit, electric leakage damages etc.The wireless explosion system then is hopeful to address these problems.
Another advantage of wireless detonator relates at explosion on-the-spot easy automatically the install blasting charge and related detonator.This for example may comprise automatic detonator filling in the hole of cutter, makes being dynamically connected certainly of detonator and corresponding each blasting charge.At the explosion scene a series of blasting charge and detonator can be installed automatically, for example can pass through robot system, the security at explosion scene will be significantly improved, because the blast operations personnel can operate explosion from far place.Yet some technical barriers that are difficult to overcome have appearred in such system, wherein much also do not solve.Obstacle that leads to automation be difficulty, particularly detonator that the on-the-spot robot of explosion handled and handled detonator require to connect or with electronics line, shock tube or similarly connect.Wireless detonator and corresponding wireless detonator system can help to address these problems, and make the easier control of enforcement of automatic mining.In addition, the artificial physical connection control of detonator will be used a large amount of labours with being connected, and requires the blast operations personnel to take much time.Opposite, blasting system does not need a large amount of labours automatically, but needs a large amount of program of time design to comprise robot system but not blast operations person's time.
Wireless detonator has had further development, and the wireless explosion system is fit to mining and uses, and comprises that detonator and system can connect automatically at the explosion scene.But still there is very big security concerns in existing wireless explosion system, if wireless system can become feasible possible alternative of traditional wired blasting system, security needs further improve.Can realize the function of complicated wiring system at explosion on-site wireless blasting system, but have the co-related risks that each inter-module of blasting system connects and can not accurately place.And the industry that develops into of wireless telecommunication system presents the significant challenge that makes new advances and new safety problem in the bursting work.
Find that through carefulness investigation wireless detonator and initiation system thereof can cause that detonator misquotes quick-fried misgivings.Do not consider the interference of occurring in nature wireless telecommunication system in fact, between wireless trigger and relevant detonator thereof, carry out communication fast and accurately and can face huge challenge yet.The wherein most important signal that need be handled by the accurate complete reception of wireless detonator is an ignition signal.The failure of communication system detonating primer can cause the danger of site operation personnel's injures and deaths.We can say and prevent that the on-the-spot detonator of explosion from misquoting quick-fried is of paramount importance.

The specific embodiment
The present invention relates to the energy that uses a kind of form and come and the detonator communication, come to detonator assembly " charging " or " power supply " with another multi-form energy, thereby make its reliable ignition.The energy of these two kinds of forms is different from other form, and it can be detected by detonator of the present invention.By form of energy disclosed in this invention as seen, it is quick-fried that the energy that uses when communication of detonator assembly of the present invention is not easy to cause misquoting of detonator basis explosive.For reliable ignition, two kinds of diverse form of energy must be detected by detonator assembly simultaneously, and not so the detonator device will be in " safe mode ".
The form of energy may adopt the form of any suitable wireless telecommunications and wireless charging or power supply, for example can be by different medium transmission.For example, the form of these energy may be including, but not limited to electromagnetic energy (comprising light), ultraviolet, radio wave, and microwave, perhaps can receive other form as electromagnetic induction or acoustic energy.The present invention advises first-selected selecting same form from above-mentioned example form of energy, both has been used for also being used to detonator assembly " charging " or " power supply " by command signal (for example from trigger) and detonator assembly communication.Yet under this environment, extraneous existing energy source must make a distinction by detonator assembly described by the present invention, thereby guarantees command signal and the energy that charges to detonator assembly can be not disturbed.In the example, if detonator assembly of the present invention uses microwave to come communication and charging, detonator assembly just can be distinguished according to wavelength or frequency so.Obviously if detonator assembly of the present invention uses different ability forms to carry out communication and charging, that needs the situation of the different energy of wavelength basis or frequency separation just to reduce.For example, detonator assembly of the present invention can then pass through radio wave with the communication of trigger by absorbing luminous energy for its charging.This is actually the particular embodiment of the present invention.Under this environment, optional light and radio receiving equipment can accurately be distinguished charging and communication signal on the detonator assembly.
In order to receive for example ARM, DISARM, with the FIRE signal and come detonator time delay being set and igniting relevant code of auto correlation trigger, plan of the present invention is used and is comprised that an energy provides the Miniature Power Unit of sufficient power supply as the telecommunication circuit in the detonator assembly.Yet this power supply does not often have enough energy to activate primary charge by firing circuit.As what discuss, the present invention uses a different system of separating fully to give detonator assembly " charging " or " power supply ", can reliably ignite primary charge according to one or more command signals thus.For example, use reception electromagnetic energy (as luminous energy or microwave) to provide energy in the embodiment of the invention for the firing circuit that activates primary charge.Like this, each detonator assembly can be programmed from trigger reception command signal by the radio-frequency communication mode.Yet, unless each detonator assembly has all received the electromagnetic energy of power supply and for firing circuit converts electric power energy to, not so can not make a response to the firing command signal.Wireless telecommunications between trigger and detonator assembly, communication ARM for example, DISARM, or ignition signal also have time delay and ignite code, all can not cause misquoting of primary charge quick-fried fully, and detonator assembly is in the intrinsic safety state thus.According to the present invention, have only detonator assembly can ignite after charging fully by an energy source that is different from the command signal communication system of (for example different wavelength or frequency) trigger fully.Just be to use different form of energy for detonator assembly provides the energy input, just can making the FIRE signal of its response trigger and the reliable firing circuit that activates ignite primary charge.
The expert will appreciate that the signal of trigger communication and energy source are different with powering for detonator assembly in itself.For example, the instrument of any wireless transmission signal and energy can be described by the present invention detonator assembly use, finishing the wireless telecommunications with trigger (for example transmission of command signal), and trigger is the energy of detonator assembly " power supply " or " charging " or the transmission of energy.Detonator assembly of the present invention can be divided into wireless telecommunications that general communication is a purpose and with the wireless telecommunications of power supply.In addition, also can use single form of energy (for example luminous energy) also has been control detonator transfer instruction signal as the detonator assembly charging both, uses different wave length when power supply and transfer instruction signal, so that detonator assembly can be distinguished effectively.For example, in specific embodiments,, and be that light energy is transmitted in the detonator assembly power supply with the optical signal of shorter wavelength higher-energy with the optical signal transmission command signal of longer wavelength less energy.The form of this luminous energy for example can adopt the form of red and blue laser.In addition, other wireless mode also can be used for comprising for example ultraviolet, radio wave and microwave, the perhaps electromagnetic energy of other form, electromagnetic induction and acoustic energy with the detonator assembly communication or for detonator assembly power supply transmission energy.
In other embodiments, detonator assembly of the present invention can receive energy and the charging of transmitting by receiver by an electromagnetic induction.Such receiver comprises that the energy received energy is as any equipment by the electromagnetic induction electric energy transmitting.For example, magnetic coupling device that has the magnetic metal material.In first-selected device, magnetic coupling device has the open extension wire that is configured to receive, and above-mentioned magnetic coupling device can produce output signal based on the electric current that passes through on the lead.For example, extension wire can optionally transmit the electric current that is adapted at causing in the magnetic coupling device magnetic flux, and promptly magnetic flux can utilize current transfer to the coiling on every side of magnetic coupling equipment.Magnetic coupling device comprises ring-type element in first-selected device, as illustrated in fig. 4.The line and the magnetic coupling device that do not have a loaded current of physical connection between the use of magnetic coupling device comprises.Therefore, in the present invention, magnetic induction constitutes a kind of wireless (or wireless to small part) energy transmission form.
First-selected embodiment of the present invention as shown in Figure 1.10 expression detonator assemblies.It is a luminous energy receiver 11 that detonator assembly comprises in the energy receiver present embodiment, and being used for receiving from what adopt in this enforcement is the laser 12 of the energy emitter 13 of laser form.And the luminous energy receiver also can be selected electromagnetic energy receiver (not sign) or other any type of energy receiver that receives any form electromagnetic energy.In another first-selected embodiment, energy receiver is the microwave energy receiver, receives microwave energy.Detonator device 10 comprises that a command signal receiver 14 receives arbitrarily the radio wave command signal 15 from trigger 16 in addition.The command signal that receives is through signal processor 17.
Therefore, at detonator device 10 illustrated in fig. 1, have only satisfied following both situations just can ignite:
At first, luminous energy receiver 11 receives sufficient luminous energy 12 with the electric power energy that produces and storage is sufficient from LASER Light Source 13, activates firing circuit 19 and ignites primary charge 18 by converter 20 and passive power source 21;
Secondly command signal receiver 14 receives ignition signal so that firing switch 22 is closed by the radio signal 15 that receives from trigger 16, thus passive power source 21 and firing circuit 19 are carried out the electric weight transmission, be discharged into firing circuit 19 to ignite primary charge 18 with the electric energy that allows to be stored in passive power source 21.
Comprise also among the embodiment in Fig. 1 that an active electrical source 25 receives for command signal and processor provides the energy.Like this, command signal reception and processor can receive the command signal from trigger all the time.
The input that needs two physically different two different energy sources from two different mediums in embodiment illustrated in fig. 1 is to ignite primary charge.The present invention also comprises more than the described more complex embodiments of Fig. 1.For example, from the command signal of trigger may further comprise may be handled and store by the detonator device time delay sign indicating number and the security feature sign indicating number as igniting code.This ignites code and can compare with the ignition code of setting in advance to determine that command signal is reliably but not misquotes quick-fried result unintentionally.For example, consistent with known security system, if the ignition code that has received is complementary with the ignition code of finishing in advance, ignition signal is then only handled and receive to the command signal processor.For safety, embodiments of the invention all are used in combination with existing mature technology in the industry.
Though in Fig. 1, do not mark, be easy to know that the parts of detonator assembly may not be installed in the capsule.For example, the luminous energy receiver may adopt the form of external antenna to extend out to far position from capsule.An embodiment comprises this principle, and as shown in Figure 2, the same among all parts of detonator and Fig. 1 is except luminous energy receiver 11.Further describe, the form that the luminous energy receiver adopts is a light capture device 30, is connected light capture device 30 and converter 20 with optical cable 31.Like this, the light capture device may be installed in the position of the luminous energy that sends from laser 13 such as on the ground suitable reception or interception.And other parts of detonator device may be installed in subsurface, or in the holing of stone.Though there is not diagram, the present invention can also further be embodied as: be installed in the light capture device from the far place of other parts of detonator assembly, other possible parts of crossover tool and detonator are installed in the position of close or adjacent light capture device.In this embodiment, luminous energy converts electric energy on ground or stone, be sent to ground next by being electrically connected the ignition primary charge.
Laser 13 can be that direct laser or laser light group provide luminous energy for a series of detonator assemblies.Can determine demolition set like this, as each detonator device, perhaps at least one light-receiving instrument of each detonator device is in the scope of light energy source such as laser.Optionally, the source of luminous energy can be from the part of trigger, also can be from parts cluster fully independently.According to the present invention, each optical receiver that should mark each detonator device may be the target in one or more luminous energy sources (for example laser).This helps to guarantee that the detonator device in the time charging that requires, also helps to make charging not influenced by the dirt of optical receiver.
In a preferred embodiment, the wireless telecommunications first-selection of trigger comprises that the two-way communication receives the signal that transmits from relevant detonator device to allow trigger, and for example, the state of detonator device, is ignited code etc. at time delay.
In another embodiment, the present invention proposes the explosion instrument and comprises a central command station away from the explosion scene that is used for the controlled blasting operation, also have one or more can receive from the command signal of central command station with pass on the trigger of signal effectively to numerous relevant detonators.
Though in Fig. 1 or Fig. 2, do not do sign, be easy to expect and be transmitted as the energy of detonator assembly charging and transmit the command signal that is used to control detonator assembly with the energy such as the luminous energy of single type.If use luminous energy, then can come the transfer instruction signal with different wavelength and charge to detonator assembly.In embodiment illustrated in fig. 3, two laser instruments that different wave length luminous energy is provided are arranged, one is used for the transfer instruction signal, and another is used to ignites the primary charge energy supply.Trigger 16 utilizes an additional laser instrument 32 that transmits light energy bundle 33 to light capture device 30.Energy beam 33 is longer than luminous energy 12 wavelength of laser instrument 13 generations, and energy is lower.The long luminous energy 33 of wavelength replaces radio signal 15 among Fig. 1 or Fig. 2 and is used for the transfer instruction signal to detonator.Trigger 16 and additional laser instrument 32 known method communication, but preferred use wireless method or direct electric communication.Can select, laser instrument 32 also can be the part of trigger.
In a preferred embodiment, the blue laser of shortwave is because of higher charging that energy transmission efficiency is useful on, and the long red laser of wavelength is used for the transfer instruction signal.Detonator assembly 10 is the same with previous device but increased optical filter 34 and recognize the wavelength that receives luminous energy.Be directed to command signal receiver 14 after having short wavelength luminous energy to be filtered like this.Receive in case be converted device and command signal receiver, signal is incited somebody to action processing as stated above.
With similar embodiment shown in Figure 3 in, can use the twin-laser device, luminous energy receiver 11 is built-in as shown in Figure 1, and the luminous energy receiver mode of employing exterior light capture device 30 as shown in Figure 2.Further can expect to use any known luminous energy emission source to launch the light of suitable wavelength.In addition, also can use and to launch two independences and the different single light energy source that can be received wavelength by detonator.
The optional embodiment of the present invention as shown in Figure 4.This embodiment comprise a lot of with at Fig. 1,2, or the similar or identical parts that show in 3.But for detonator device charging be by way of electromagnetic induction rather than by some other wireless tool.In Fig. 4, identified the line of selecting to transport from the electric current of power supply (not sign) 40 has been arranged.Power supply (not sign) can also can be a separate component from the part of trigger or central command station.Under any circumstance, line 40 all will twine by an annular magnetic coupling device 41, does like this when electric current process electric wire and can produce magnetic flux in magnetic coupling device.Be converted to electric power energy effectively at 42 li magnetic fluxs of seal wire, this seal wire twines part annular magnetic coupling device 41 and links to each other with another parts of detonator device 10.In order to convert a kind of electric power energy form that is suitably for passive power source 21 power supplies to, seal wire 42 links to each other with crossover tool 20.In optional embodiment, also can directly link to each other seal wire 42 and change from the energy of power supply to line 40 with passive power source.In this case, in some optional embodiment, then can no longer need converter at least.
Though strictly speaking embodiment illustrated in fig. 4 is not " wireless " completely, it within the spirit and scope of the present invention.Electromagnetic induction can be used as a kind of selection that form of energy is provided as a kind of method for the detonator power supply, is different from general command signal communication 15 from trigger 16.Because this reason, detonator device 10 can be distinguished command signal and charging signals effectively, and and if only if when satisfying following condition, and primary charge just can be detonated:
(1) passive power source 21 is by line 40 electromagnetic induction, and magnetic coupling device 41 and seal wire 42 are recharged or are recharged fully;
(2) trigger 16 transmission fuze signals 15 (for example by radio wave or electromagnetic energy), receive and handle by command signal receiver 14 (handling) with processor 17, make firing switch 22 closures thus and the electric power energy of storage is discharged into firing circuit 19, cause igniting primary charge 18.
Though the use in the conversion of the annular shown in Fig. 4 is in the field of business known, it is communication or other the general communication that is used for detonator/detonator assembly command signal that tradition is used.This is opposite with the present invention, and the present invention has used electromagnetic induction for the command signal communication and in order to ignite to detonator assembly charging.For the use of charging, the seal wire 42 that is wrapped on the annular magnetic coupling device may needn't be too accurate with respect to the device that is used for the equivalence of transfer instruction signal.After all, the purpose of using the circular device in this device is charging, the failure of circular device can cause lacking charging or charge insufficient, thereby detonator assembly can not be ignited, this causes great risk may not can for the blast operations personnel.It is no coming the failure of transfer instruction signal with circular device, may cause that the state of detonator device is uncertain to have an inevitable safety problem.With respect to the annular transmitter that is used for the transfer instruction signal, the annular transmitter that is used to charge not too accurately also is an acceptable.For example, this equipment also is to use the poor slightly seal wire of accuracy 42 to be wrapped on the magnetic coupling device 41.
