The specific embodiment
Below in conjunction with accompanying drawing principle of the present invention and characteristic are described, institute gives an actual example and only is used to explain the present invention, is not to be used to limit scope of the present invention.
Each time-delay sparking gear links to each other with an instant electric detonator respectively, and guarantees that all electric caps all reliably are connected on the time-delay sparking gear, more a plurality of time-delay sparking gears is connected to initiator, sets up into the blasting cap initiation network.Initiator carries out connection reliability according to following method control time-delay sparking gear and detects, and control time-delay sparking gear is according to the accurate detonating capsule of setting of delay time.As shown in Figure 1, concrete steps are following:
The first step, initiator sends instruction at least one time-delay sparking gear, and this instruction is used to set the defer time count value of detonating of at least one time-delay sparking gear, and detects the connection reliability of time-delay sparking gear and initiator.This instruction comprises targeting part, geocoding part, defer time part successively, wherein,
Targeting part is used to instruct the time-delay sparking gear to accomplish the data decode to instruction;
Whether the geocoding part is used for the checking instruction to this time-delay sparking gear;
The defer time part is used to set the defer time count value of this time-delay sparking gear.
In second step, initiator is set the time reference that at least one time-delay sparking gear delays to count.
In the 3rd step, the time-delay sparking gear is adjusted the time reference of time-delay sparking gear counting based on the control of initiator, and the detonator that after the defer time counting is accomplished, detonates and link to each other with the sparking gear of delaying time.
In the above-mentioned first step, initiator can detect the connection reliability of time-delay sparking gear by following two kinds of methods.
First kind of implementation is: initiator provides a homophase d. c. voltage signal and an anti-phase d. c. voltage signal to the time-delay sparking gear again after the time-delay sparking gear sends above-mentioned instruction, to realize the detection to time-delay sparking gear connection reliability.
If the time-delay sparking gear can correctly be discerned the instruction that initiator sends under homophase d. c. voltage signal condition, the signal that then reliably is electrically connected to the initiator feedback; If the time-delay sparking gear is recognition instruction correctly, then when receiving the anti-phase d. c. voltage signal, make the feedback that reliably is electrically connected to initiator.If behind above-mentioned homophase d. c. voltage signal and anti-phase d. c. voltage signal, initiator does not all receive the signal that the time-delay sparking gear returns, and thinks that then this time-delay sparking gear does not reliably connect.Like this, realized that not only time-delay sparking gear connection reliability detects, also realized the nonpolarity connection of time-delay sparking gear.
Second kind of implementation is: initiator is to send instruction (being defined as forward instruction here), homophase d. c. voltage signal (being defined as the forward dc voltage signal here) and the reverse instruction after the time-delay sparking gear sends the instruction upset to be provided, to the time-delay sparking gear homophase d. c. voltage signal (homophase d. c. voltage signal here and reverse instruction same-phase with the reverse instruction homophase to be provided again to the time-delay sparking gear again to the time-delay sparking gear; Whether mode formation after but it overturns above-mentioned forward dc voltage signal) detects the time-delay sparking gear and reliably is electrically connected.
In this implementation, initiator can a plurality of forward instruction of running fire and forward dc voltage signal, and a plurality of reverse instruction of running fire and reverse voltage signal are realized all time-delay sparking gear connection reliability in the network are detected again.After initiator also can send single forward instruction and forward dc voltage signal, continue again to send single reverse instruction and reverse voltage signal, repeat above-mentioned process of transmitting, realize all time-delay sparking gear connection reliability in the network are detected.
Further, initiator is encoded according to graceful Chester to the instruction that the time-delay sparking gear sends; The binary coding that targeting part in the instruction is T by four predetermined bit width " 0100 " constitutes.The time-delay sparking gear can adopt Manchester code encoding/decoding mode to accomplish the data decode to instruction; But when adopting Manchester encoding and decoding to carry out data decode; In the middle of growing " 0 " or long " 1 " serial data, exist under the situation of sudden change; Possibly have the situation of sampling less than this sudden change, this has just caused the data decode mistake.Further, the present invention provides a kind of and accomplishes the data decoding method to instruction according to following steps.
If width D is between 1.8 times to 2.2 times of predetermined bit width T; With 2 times, with D=2T example promptly, the sparking gear execution in step three of then delaying time; To address coded portion and the decoding of defer time partial data, accomplish the defer time of detonating of this time-delay sparking gear is set;
If width D is between 1.3 times to 1.7 times of predetermined bit width T; With 1.5 times; Be example with D=1.5T promptly, four pairs of address coded portions of the sparking gear execution in step of then delaying time and the decoding of defer time partial data are accomplished the defer time of detonating of this time-delay sparking gear are set;
Step 3; With second edge signal of two identical edge signals, backward delay scheduled time (this scheduled time be predetermined bit width T 10% to 40% between any value) time point serve as the time zero of sampling; With half of bit wide D is that the sampling period, (sampling period was 1/2D=1/2 * 2T=T), instruction is sampled here.Shown in the 2-b among Fig. 2, time point g is the sampling time zero, and h is next sampled point: if sampled point is a low level, then this sampling number is according to being decoded as " 1 "; If sampled point is a high level, then this sampling number is according to being decoded as " 0 "; Form the data decode waveform of instruction;
Step 4; Second edge signal of two identical edge signals postpone 2/3rds backs of bit wide D, again delay scheduled time (this scheduled time be predetermined bit width T 10% to 40% between value arbitrarily) time point be the sampling time zero; With 2/3rds of bit wide is that the sampling period, (sampling period was 2/3D=2/3 * 1.5T=T), instruction is sampled here.Shown in the 2-c among Fig. 2, time point g is the sampling time zero, and h is next sampled point: if sampled point is a low level, then this sampling number is according to being decoded as " 0 "; If sampled point is a high level, then this sampling number is according to being decoded as " 1 "; Form the data decode waveform of instruction.
Carry out brief account in the face of detonator network initiation control method of the present invention down:
After accomplishing the detonator network organizing; Initiator at first sends instruction to the time-delay sparking gear; This instruction can detect the connection reliability between time-delay sparking gear and the initiator; Judge that whether all time-delay sparking gear all reliably is electrically connected with initiator, guarantees the proper communication between time-delay sparking gear and initiator.In addition; The instruction that initiator sends also is used to set the defer time count value of detonating of this time-delay sparking gear; The time-delay sparking gear receives and data decode is carried out in above-mentioned instruction; Whether decision instruction, then is saved to the defer time count value n that decodes in the time-delay sparking gear if to this device to this time-delay sparking gear.
Then, the peripheral operation personnel pass through initiator to time-delay sparking gear a reference value input time Δ, and the time-delay sparking gear calculates the defer time t=n * Δ of this time-delay sparking gear according to defer time count value n and time reference value Δ.
At last, the time-delay sparking gear sends time break to coupled electric cap behind the time t that accomplishes the extension countdown, accurately controls the electric cap completion and detonates.
In above-mentioned initiation control method,, can in each time-delay sparking gear, a basic extension count value n be set earlier in order to increase the scope that defer time is set
0, the sparking gear of delaying time then receives the defer time count value n that initiator sends again, with (n
0+ n) as the final defer time count value of this time-delay sparking gear, the defer time value of the electric detonator initiation that calculate to obtain to link to each other with this time-delay sparking gear according to the time reference Δ again is t=(n
0+ n) * Δ.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
