 As shown in Figure 4, the method includes the following steps:

 Step S602: Receive a detonator group number input by the user.

Wherein, one detonator group may include one or more detonators, and may also include zero detonators, that is, the number of detonators in one detonator group may be zero. When the number of detonators in a detonator group is zero, there is only an inter-group delay, and there is no intra-group delay. For example, the first detonator group, the second detonator group, and the third detonator group are three adjacent detonator groups, the number of detonators in the second detonator group is zero, and the detonators are present in the first detonator group and the third detonator group. The first detonator in the third detonator group (the detonator with the smallest delay in the third detonator group) and the last detonator in the first detonator group (the detonator with the largest delay in the first detonator group) have two delay intervals of two Delay between groups.

 When the detonator group is numbered by using the method of the embodiment of the present invention, FIG. 7 can be used. The numbering shown, that is, multiple detonators in the same group share a single number. Therefore, in the blasting project, it is not necessary to match the number of the detonator with the number of the drill hole, and the multiple detonators in the same group need not be distinguished, and the detonator can be loaded into any blasthole in the group; the operation is simple. It is not easy to make mistakes, which simplifies the construction process and effectively improves the construction efficiency.

 Step S604, setting the delay time of the detonator in each detonator group in units of the detonator group.

In the invention, the delay time of the detonator is set in units of the detonator group, and the batch setting of the detonator delay time can be realized, and the extension time of the detonator setting is effectively shortened compared with the prior art setting the delay time for each detonator. Time has improved construction efficiency.

 Step S606: Send a detonation signal to each detonator group so that the detonators in each detonator group detonate when the corresponding delay time arrives.

 In the present invention, the delay time of the detonator in each detonator group can be separately set in the following manner in the detonator group:

 First, an inter-group delay is obtained, wherein the inter-group delay is the delay interval between two detonators that are adjacent to the detonation.

 Then, an intra-group delay is obtained, wherein the intra-group delay is an extension time interval between two detonators of adjacent detonation within the same detonator group.

 The extension time of each detonator is set according to the detonator group number, the inter-group delay, and the intra-group delay.

For the extension time of each detonator according to the detonator group number, the inter-group delay, and the intra-group delay, the following method can be used to calculate the extension time of the first detonator:

 (11), obtaining the group number of the first detonator group, wherein the first detonator group is any detonator group.

 (12), obtaining an index number of the first detonator in the first detonator group, wherein the first detonator is any detonator in the first detonator group.

 (13), calculating the delay time of the first detonator according to the group number of the first detonator group and the index number of the first detonator.

For the extension time of each detonator according to the detonator group number, the inter-group delay, and the intra-group delay, the following method may also be used to calculate the extension time of the first detonator:

 ( twenty one Obtaining a maximum delay value of the second detonator group, wherein the second detonator group is the previous detonator group of the first detonator group, and the group number of the first detonator group is greater than the group number of the second detonator group 1 The maximum delay value of the second detonator group is the deferred value of the detonator with the largest deferred value in the second detonator group.

 (22), obtaining an inter-group extension, wherein the inter-group extension is an extension time between the first detonator group and the second detonator group.

 (23), the extension within the group is obtained, wherein the delay within the group is the extension time between two detonators of adjacent detonation in the first detonator group.

 (24), obtaining an index number of the first detonator in the first detonator group.

 ( 25 Obtaining an index number of the initial detonator in the first detonator group, wherein the initial detonator is the detonator with the smallest delay time in the first detonator group. as well as

 (26 Calculating the deferred value of the first detonator according to the maximum deferred value of the second detonator group, the inter-group delay, the intra-group delay, the index number of the first detonator in the first detonator group, and the index number of the initial detonator in the first detonator group .

 Among them, for (26 Calculating the extension of the first detonator according to the maximum delay value of the second detonator group, the inter-group delay, the intra-group delay, the index number of the first detonator in the first detonator group, and the index number of the initial detonator in the first detonator group Value, the delay value of the first detonator can be calculated using the following formula:

 Deferred value of the first detonator = maximum deferred value of the second detonator group + inter-group delay + intra-group delay * (The index number of the first detonator in the first detonator group - the index number of the initial detonator in the first detonator group).

 5 is a flow chart showing the operation of a tunneling and detonating device according to an embodiment of the present invention.

 Figure 5 It is shown that, after the electronic detonator detonation control method of the embodiment of the present invention is adopted, in the embodiment of the present invention, the following method may be used to set the delay time of the tunnel excavation detonating device:

 Step (51), delete the detonator data.

 There are 3 ways to delete detonator data:

 1 Delete all detonator data. When this mode is selected, you can delete data for all registered detonators.

 2 Delete the wrong detonator data. After selecting this mode, you can select the number of the detonator with the wrong data and delete the data of the error detonator.

 3 Delete the specific detonator. After selecting this method, you can select the specific detonator number and delete the selected detonator data.

 Step (52), grouping the detonators.

The detonators in the blasting area are divided into different groups, and the detonators in each group are registered respectively. In this way, the detonators in each group can be operated as a whole, which is beneficial to shorten the construction. Time to improve construction efficiency.

 Step (53), set the group delay parameter.

 Group delay parameters may include group number, inter-group delay, and intra-group delay. This operation allows you to set an extension time for each detonator in the blasting network.

 Step (54), detecting the network and performing a detonation process. It should be pointed out that the detection network is the preferred process.

 6 is a flow chart of registration of an electronic detonator in accordance with an embodiment of the present invention.

When registering an electronic detonator, after entering the group number of the group to be registered, the minimum unused number in the corresponding group can be automatically obtained to register the new detonator at this number. Through this process, registration of detonators in each detonator group can be completed.

 For the number of detonators, the number of detonators in the same group is the same, see Figure 7. As shown in the figure, it is only necessary to put the detonators belonging to a certain group into the corresponding group according to the number, without the one-to-one correspondence with the operation mode of the prior art, the operation is simple, the construction time is greatly shortened, and the construction time is effectively improved. Construction efficiency.

 8 is a flow chart of setting a group delay parameter in accordance with an embodiment of the present invention. In Figure 8 In the flow chart shown, the order of 'input group number', 'input group delay' and 'input group delay' can be exchanged.

Because of the group registration, this makes the detonator in the blasting area have a group distinction. When setting the delay time, all the detonators in the network can be set at one time by setting the delay time between the adjacent detonation groups (inter-group delay) and the delay time between the detonators in the group (intra-group deferral). The extension time is set.

 For example, use the following formula to calculate the delay time for a detonator:

 Detonator delay = maximum delay value in the previous group + inter-group delay + intra-group delay * (The index number of this detonator in this group - the index number of the initial detonator in this group).

 When the group number is 1, the maximum delay value of the previous group is 0, and the delay between groups is 0. . The index number refers to the number of positions in which all detonators in the group are arranged according to the delay time from small to large, usually a continuous positive integer. For example, there are 5 detonators in a group, and the delay time is 5ms and 10ms respectively. , 15ms, 20ms, 25ms, assuming that the index number of the initial detonator in the group (that is, the detonator with a delay of 5ms) is 1, the extension time is 10ms, 15ms, The index numbers of the 20ms and 25ms detonators are 2, 3, 4, and 5 respectively. If the index number of the initial detonator in this group is 0, the delay time is 10ms, 15ms, The index numbers of the 20ms and 25ms detonators are 1, 2, 3, and 4, respectively.

In the present invention, the detonator delay value can also be modified by inputting the group number, inter-group delay, and intra-group delay. After modifying the deferred parameters of a group, the detonator delay value with a larger group number will also be automatically adjusted.

In the present invention, the inter-group delay refers to the delay interval between two groups of adjacent detonation, specifically, the detonator that is detonated in the first detonation group (ie, the detonator with the largest delay time) and the group that is in the post-detonation group. The delay interval between the first detonated detonator (ie, the detonator with the least delay).

 In the present invention, the intra-group delay refers to the delay time interval between two detonators that are adjacent to each other in the same group.

It should be noted that the steps illustrated in the flowchart of the accompanying drawings may be executed in a computer system such as a set of computer executable instructions, and, although shown in the flowchart, The steps shown or described may be performed in an order different than that herein.

After the extension is set, the number of the detonator is marked with the number corresponding to the detonator. According to the detonator loading diagram in the blasting scheme, the numbered detonators are loaded into the blasthole one by one.

 Specifically, the blasting process is as follows:
