The specific embodiment
Wireless initiation system can help winding placement complicated in the scene of detonating, and avoids irrational layout.Yet the development for the wireless communication system of blast operations has proposed great brand-new challenge to industry, comprises new safety issue.
Through earnest investigation, find that some part of wireless detonator and initiation system exists unintentionally or the relevant issues of unexpected detonating primer.Rapid and correct communication between initiator and detonator is no matter what state of wireless communication system is a very big challenge to the detonator that links to each other.Important problem is that signal must be fit to, accurately.Communication system goes the communication system of detonating capsule malfunctioning with instruction, or some the time unaccommodated cap sensitive program can both arrive the serious injured or dead of the personnel that cause field operation.Therefore, avoid unintentionally or unexpected detonating primer is vital to blast operations.
The utility model provides a wireless detonator assembly, comprises the equipment that detonates and the igniting method thereof of this wireless detonator assembly.A built-up section of using in the utility model wireless detonator assembly goes to avoid the danger of detonating primer unintentionally.Prior characteristics are, wireless detonator assembly of the present utility model adopts the command signal receiving processing circuit of sufficient power operation assembly, but not enough electric energy can activate firing circuit once in a while, ignite primary charge, radio communication is to send by the initiator that links to each other with the wireless detonator assembly, for example: wait to send out (ARM), remove and wait to send out (DISARM) or igniting (FIRE) signal, also have time delay, the communication of igniting code, because the characteristic " safe mode " of detonator inside, it is quick-fried to avoid detonator to misquote greatly.
Wireless detonator assembly of the present utility model comprises: the detonator that contains primary charge; Can receive and the receiving processor of handling at least one wireless signal that sends from the equipment of detonating that links to each other; Electrical storage device; The power supply of electric energy can be provided to signal receiving processor; The firing circuit that is connected with energy storage device.According to the ignition signal that sends from initiator, the electric energy in electrical storage device is given firing circuit discharge generation electric current, ignites primary charge with this.
A part of the present utility model as shown in Figure 1.Usually, detonator assembly 10 is made up of a command signal receiver 11 and a command signal processor 12.Receiving processor can be taked the form that unites two into one, maybe can form reception and processing that a recoil simulator is used for signal.Signal receiver mainly relies on the wireless command signals that receives from initiator.For example wireless command signals is spread out of received signal device then as radio wave and can be received with the form of radio frequency (RF) antenna.If the wireless command signal from initiator comprises some electromagnetic-energies such as laser, receiver can be formed the light wave trap setting.At any time, the wireless detonator assembly all receives and handles by receiver 11 and 12 pairs of signals of processor.

Fig. 1 illustrates part emphatically of the present utility model, comprises the use of external box 19.External box is one and is used for the part in the wireless detonator assembly being selected and keeping near the device of these parts ground.External box is placed on the ground or a definite position, boring near easier reception wireless signal, in order to pass the signal to detonator, preferably be placed on boring below.In the utility model embodiment, each external box comprises the part that one or more wireless detonator assemblies is selected.And, allow sensitive compressible members (clock unit) to be placed on external box away from the place of holing.
With reference to Fig. 1, power supply 14 is used for providing power supply to three parts, signal receiver 11, signal processor 12 and electrical storage device 13.Power supply can provide sufficient voltage to signal receiver in the wireless detonator assembly 11 and signal processor 12 in such a way, and can charge to electrical storage device.Power supply 14 is producing the low-voltage that can ignite primary charge once in a while with under the direct-connected condition of firing circuit.In this way, only when voltage ratio predetermined threshold value voltage is high, could ignite primary charge.In fact, electrical storage device 13 plays the effect of supercharging.By receiving the electric energy of power supply, temporary transient stored energy responds ignition signal and discharges electric energy to firing circuit, and electrical storage device provides voltage or electric current to initiator, and this value has surpassed ignites required threshold voltage or the electric current of primary charge.
As shown in Figure 1, in fact power supply 14 is only powered to 11,12 communications portion in the wireless detonator assembly.One independently power supply be used to power to electrical storage device.This independently power supply as the part in the wireless detonator assembly, for example battery.
Independent current source comprises that also extra energy source is used for charging to the electrical storage device of wireless detonator assembly medium-long range.The wireless detonator assembly comprises that also activating power is used for providing sufficient power supply to wireless telecommunications, but not enough electric energy just can cause the triggering of detonator primary charge.Wireless detonator is by two diverse power supply power supplies, and one is the radio wave form that is used for general communication, and another is luminous energy (can be changed into electric energy by the parts of a detonator) form, powers to initiator.
Fig. 2, similar to the explanation of explanation of the present utility model and Fig. 1.But both advantages are combined together.At first, a charge switch 20 has been added between power supply 14 and the electrical storage device 13.When the position that charge switch 20 is transferred to out, between power supply 14 and electrical storage device 13, do not have.Transfer out by " keeping activating " signal on the initiator, receive " keeping activating " signal by receiver 11 and processor 12, signal processor 12 makes charge switch 20 closures, has set up again to be electrically connected between power supply 14 and electrical storage device 13.This transformation has caused the basic reception that electrical storage device becomes charged state or keeps ignition signal in the driving wireless detonator assembly.Signal is a lasting signal " to keep activation ", to such an extent as to the wireless detonator assembly is at any time preferentially lighted a fire than the signal time that suitable signal feedback is arranged." keep activating " signal and comprise that an independent signal makes the preferentially igniting at any time of wireless detonator assembly.The wireless detonator assembly can be the maintenance proper state of detonating.
Shown in Figure 2, discharger 21 is connected with the simple of electrical storage device 13, absorbs electric energy by an approach from electrical storage device rather than from initiator.If the position that charge switch 20 is transferred to out does not have electricity between power supply 14 and electrical storage device 13, cause a large amount of minimizing of electrical storage device 13 charge numbers.If abundant from the electrical storage device discharge, electrical storage device can trigger the ignition primary charge, according to the ignition signal that links to each other with initiator.Lacked from " keeping activating " signal that initiator sends and to have caused the charging device discharge, the wireless detonator assembly is adjusted to a safe mode, can be unlikely to ignite primary charge like this, the appearance of other influences may cause once in a while or ignite primary charge unintentionally (as the rub-out signal for igniting, electromagnetic interference, incorrect energy transmission).
Fig. 2 explanation is used according to any type of discharge of utility model that proposes, all be continue or selectively from power supply, draw electric energy, as from resistance, absorbing energy.Because this reason, a leaky capacitor or other charging memory devices are described with " discharger " according to its feature.Another selection is the switch in short-term that links to each other with circuit, if " keeping activating ", signal was not received in certain time interval, then it just is activated.
The electric energy that the destructor that is not activated can go to absorb stand-by power supply by the circuit of change and provide is finished.For example, the equipment of detonating comprises can open any one or a plurality of stand-by power supply, activating power, and the blasting fuse head, detonation chain or other explosion equipments, this method is used in discharge circuit, Creepage capacitance or suitable equipment.
The variation of Fig. 2 explanation is presented on Fig. 3.The part of describing before this part comprises.This part is arranged a kind of different mode and further specifies its advantage.
Especially discharge circuit 21, replaced going to change by charge switch with charging memory device direct-connected mode the electric energy of electrical storage device.When charge switch 20 is opened, between discharger 21 and electrical storage device 13, be electrically connected.Yet contrast Fig. 2, when charge switch 20 was opened, power supply 14 just was not connected with electrical storage device 13.Power supply does not have under the situation of work, and discharger can discharge the electric energy of electrical storage device.When the wireless detonator assembly was responded " keeping an activating " signal from the equipment of detonating, the charge switch closure caused the loss of electrical storage device and discharger electric weight, has set up at power supply 14 and electrical storage device 13 to be electrically connected.This mode, energy storage device is by power source charges.Comparing as a result with Fig. 2, the charging and the discharge of electrical storage device are very effectively with rapidly.And according to Fig. 2, this method is necessary, and mainly when making the charging rate of power supply 14 more closed than the speed charging quickly switch 20 of discharge circuit, otherwise electrical storage device 13 can not be recharged and feeds back on " keeping activating " signal.This need not illustrate in Fig. 3 that when charge switch 20 closures, although the charging rate of power supply is less than the velocity of discharge of discharge circuit, charging also can take place.
The utility model links to each other with equipment with other unit for priming device provides at least one wireless detonator assembly, and this is to cause the necessary condition of detonating.For example extra unit and equipment also include, but are not limited to this: equipment of detonating can receive the control signal from console for centralized control, by radio communication signal is passed to the wireless detonator assembly; The charging equipment that detonates.Best is, the instrument that detonates will comprise that also console for centralized control is used for control signal is passed to each initiator, and each initiator is carried out time break, passes on signal simultaneously at least one wireless detonator assembly.
