Abstract
The invention provides two execution schemes to a delay time setting process of an electronic detonator explosion initiating device. One execution scheme comprises: sequentially executing a clock calibration process for W1 times and a writing delay time process for W2 times; and outputting an error information table. The other execution scheme comprises: executing a delay time setting process for W times; and outputting the error information table. In the clock calibration process, calibration commands can be sent to all detonators first and then state information is read back one by one; or in the clock calibration process, time calibration commands are sent to detonators one by one first, and then time frequency is calculated according to a calibration pulse fed back and is stored. In the writing delay time process, a writing delay time command is sent out directly or after delay time data adjustment. In the delay time setting process, a clock calibration command is sent to one detonator first and the clock frequency is calculated according to the calibration pulse fed back; and after the delay time data adjustment, the writing delay time commands are sent to the detonators. Thus, the explosion initiating device capable of calibrating the clock frequency of the electronic detonators is realized.

Step F 9 finishes originally to write the defer time process.
In the scheme one of clock alignment process shown in Figure 4, the step C1 clock alignment instruction that all electric detonators send in blasting network is a global command.The calibration pulse that this instruction is T by preset number m synchronous study head, clock alignment command word and a preset number n predetermined period constitutes successively, and is shown in figure 10.Priming device utilizes himself stablizes accurate clock source, sends study head and calibration pulse sequence synchronously, supplies the counter of chip internal that it is carried out fragmentation count:
(1) when the control chip in the electric detonator receives the edge signal of synchronous study head, the counter that promptly starts chip internal is counted the number of synchronous study head.Then, by the central processing unit of chip internal calculate that serial communication interface should adopt, respectively with preset communication baud rate and preset sampling phase clock number corresponding, the RC oscillator, thereby the data reception opportunity and the counting interval of adjustment electric detonator.This just can guarantee to have introduced the electronic detonator control chip of RC oscillator, though the RC oscillator exist temperature float, the time float, problem such as parameter variation, the control instruction of still can reliable reception electric detonator outside sending.
(2) when the control chip in the electric detonator receives the calibration pulse sequence; The central processing unit of chip internal is according to the preset number n of count value, calibration pulse and the predetermined period T of calibration pulse; The clock frequency f of the RC oscillator of computing chip self, and the result is stored in chip internal.It calculates principle and can be described as: expressed time the n ' * T of the calibration pulse that priming device sends (n '=1; 2,3 ... N) at the count value N of chip 200 clock internal numbers; Be inversely proportional to the clock cycle 1/f of chip internal RC oscillator; Promptly the clock frequency f with the RC oscillator is directly proportional, then n ' * T=N/f is arranged, therefore: f=N/ (n ' * T).Wherein, to taking of all count value N storing in the chip internal central processing unit inner buffer, the value of the periodicity n ' of the calibration pulse that should adopt when calculating is corresponding.Calibration pulse with first cycle is an example, and when receiving edge signal 1, the counter of chip internal starts; When receiving edge signal 2, read this count value N constantly
1And preserve; When receiving edge signal 3, read this count value N constantly
2And preserve, so far accomplish the reception and the counting of first period regulation pulse.When calculating clock frequency f, periodicity n ' should be taken as 1, and count value N should be taken as N
2The rest may be inferred.When Practical Calculation, the precision of the clock frequency f that calculates for raising, sectional calculates the value of several clock frequencies f and takes the mean.Segmentation method can adopt the at interval method of a clock frequency f of several computation of Period, perhaps based on the additive method of this principle.
In clock alignment shown in Figure 10 instruction, calibration pulse is carried out following calibration pulse transmission flow transmission by control module, like Figure 11:

Step D4, whether the central processing unit monitoring arrives preset value v: if arrive, then carry out step D5; If no show then continues monitoring and waits for arrival.
Step D5, central processing unit transmits control signal to timer, stops timer.
Step D6, central processing unit write the preset value u of calibration pulse high level width in timer.
Step D7, control module transmits control signal to the signal modulation and transmission module, makes it to export the rising edge signal.
Step D8, central processing unit transmits control signal to timer, starts timer.
Step D9, whether the central processing unit monitoring arrives preset value u: if arrive, then carry out step D10; If no show then continues monitoring and waits for arrival.
Step D10, central processing unit transmits control signal to timer, stops timer.
Step D11 subtracts 1 with the value of presetting number n, as the value of new n, that is, and n=n-1.
Step D12, judge whether the value of preset number n is 0: if 0, then carry out step D13; If be not 0, then return step D1.

Step M4, judge that whether this electric detonator is for setting the extension state according to said status information: if set the extension state, execution in step M16 then; If do not set the extension state, then carry out step M5;
Step M5 is to this electric detonator tranmitting data register calibration command;
Step M6, said control module is carried out the signal receiving process:
If receive the clock alignment pulse that this electric detonator returns, then this electric detonator is put clock alignment and successfully indicate in said priming device inside; Carry out step M7 then;
If do not receive, then this electric detonator is put the clock alignment error flag in said priming device inside; Execution in step M15 then;
Step M7 is with said E
1Value subtract 1, as new E
1Value, i.e. E
1=E
1-1;
Step M8, said control module is counted the alignment of waveforms of plural n cycle t in the said clock alignment pulse, and count value is designated as F;
Step M9 according to the value of said n, said t and said F, calculates the clock frequency f of this electric detonator;
Step M10 reads the defer time data of this electric detonator;
Step M11 carries out defer time data adjustment flow process;
Step M12 writes the defer time instruction to this electric detonator transmission;
Step M13, said control module is carried out the signal receiving process:
If what receive that this electric detonator returns writes the defer time signal that finishes, then this electric detonator put and write defer time and successfully indicate in said priming device inside; Execution in step M14 then;
If do not receive, then this electric detonator put and write the defer time error flag in said priming device inside; Carry out step M15 then;
Step M14 is with said E
2Value subtract 1, as new E
2Value, i.e. E
2=E
2-1;
Step M15 subtracts 1 with the value of said L, as the value of new L, i.e. L=L-1;
Step M16, judge whether the value of said L is 0: if 0, then carry out step M17; If be not 0, then return said step M2;
Step M17 finishes this extension setting process.
13., it is characterized in that according to claim 7 or 12 described defer time setting process:
Said clock alignment instruction is made up of the identity code of synchronous study head, clock alignment command word and a said electric detonator successively.
14., it is characterized in that according to claim 9,10 or 12 described defer time setting process:
Said write defer time instruction by synchronous study, write the identity code of defer time command word, a said electric detonator and the defer time data of this electric detonator constitute successively.
