Description
Technical Field

Background
The electronic detonator, also called digital electronic detonator, digital detonator or industrial digital electronic detonator, adopts an electronic control module to manage and control the detonator initiation process. In the detonator detonating networking process, two long leg wires are generally used as buses of the detonator, all electronic detonator tubes are mounted on the long leg wires, and an operator performs operations such as registering, networking, detonating and the like uniformly through an initiator end. In general, the explosion site environment is extremely complex and severe, the safety and reliability of explosion are also reduced, and particularly under the condition of underground mine with high humidity and high temperature, a larger test is put forward on wired connection. Meanwhile, the detonator blasting is carried out in a wired mode, so that workers are required to carry out field investigation, and the operation cost is increased.
In recent years, wireless communication technology has been widely used in various industries in China, such as transportation, medical treatment, food, military, etc. The wireless communication device encodes the data, sends the encoded data to the wireless receiving device, decodes the data by the receiving device, analyzes the corresponding command and executes the command. Compared with the wired mode for networking initiation, the wireless communication mode has more excellent stability and cost advantages.
For multi-node initiation of wireless electronic detonators, time synchronization is the most important in the initiation process, and an initiator (main equipment) needs to synchronously control all detonators (auxiliary equipment), because the working environment of the wireless electronic detonators has large interference to wireless communication, after an initiation instruction is sent, part of wireless detonators often cannot receive the initiation instruction, or part of wireless detonators cannot analyze even if receiving the instruction due to too much noise in signals, so that synchronous initiation cannot be realized under the condition of large interference to wireless communication.

Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present invention, and are not intended to limit the scope of the present invention.
As shown in fig. 1, a wireless electronic detonator detonation synchronous control method comprises the following steps:
step 1, responding to a received wireless message sent by an initiator module, and analyzing the received wireless message; the initiator module periodically transmits a wireless message, wherein the wireless message comprises an initiation instruction and a message sequence number, and the message sequence number i represents the wireless message transmitted in the ith period.
Step 2, responding to the analyzed message sequence number and the initiation instruction, acquiring a first preset time corresponding to the message sequence number according to the message sequence number, and timing the first preset time; if the message serial number and the initiation instruction are analyzed from the current wireless message, the wireless message sent by the initiator module in the subsequent period is not received; each message sequence number corresponds to a first preset time.
And step 3, responding to the timing reaching the second preset time, and sending the analyzed detonation instruction to the detonator controller.
According to the method, based on a single broadcasting mechanism, the detonator module periodically transmits the wireless message, and the detonator module acquires the corresponding first preset time according to the message serial number in the wireless message, and realizes detonation synchronization through time timing, so that the detonator module can finish the accurate synchronization of detonation and implement detonation as long as receiving any frame of detonation instruction and message serial number, and the problem that the detonation cannot be synchronized under the condition of large wireless communication interference is solved.
The implementation structure of the method can be shown as fig. 2, and the wireless electronic detonator initiation synchronous control device mainly comprises an initiator module and a plurality of detonator modules which are in wireless communication with the initiator module.
The initiator module comprises an initiator body and a wireless module, and a wireless command technical terminal is constructed by the initiator body and the wireless module; the initiator body can be an app platform, and sends wireless messages to all detonator modules through the wireless module, and receives detonator state data fed back by all detonator modules through the wireless module.
The detonator module comprises a wireless module, a conversion card and a detonator controller, wherein the wireless module of the detonator module and the wireless module of the detonator module form a wireless network, and the wireless module of the detonator module is mainly responsible for transmitting messages issued by the detonator module. The conversion card adopts the wireless electronic detonator detonation synchronous control method to carry out detonation synchronous control, and is also responsible for driving the detonator control module to complete functions of various detonator networking, detonator state detection and the like, and feeds back networking results and detection results to the detonator module. The detonator control module is an action execution unit and is an executor of actions such as charging, checking and detonating.
Assuming that the initiator module controls the N detonator modules through the wireless network, when the initiation is executed, the initiator module needs to ensure that all detonator modules execute the initiation command at the same time, so the synchronous control method can be divided into the following three stages:
1. timing is carried out on all modules in the network;
the minimum reference time of the initiator module and the detonator module in the network is set at the same reference time unit 'delta', namely the minimum count time units of the initiator module and all detonator modules are set at the same value 'delta'.
2. The initiator module periodically transmits a wireless message;
considering that the explosion field environment factors can cause frame loss in the communication process, when the explosion is executed, the initiator module periodically transmits wireless messages, and continuously transmits the wireless messages to all detonator modules at fixed interval time epsilon multiplied by delta for M times, wherein in the wireless messages, besides the explosion instruction, message serial numbers are packaged and transmitted together, the message serial numbers are consistent with the cycle numbers, and if the message serial number i represents the wireless message transmitted in the ith cycle.
3. The detonator module receives and analyzes the wireless message, in particular to a conversion card;
when the detonator module receives the wireless message sent by the initiator module at a certain time, analyzing the received wireless message, discarding the wireless message if the analysis result is incomplete or failing to analyze, continuing to receive the wireless message, and if the message serial number and the initiation instruction are analyzed, acquiring a first preset time corresponding to the message serial number according to the message serial number, and timing the first preset time. In order to save communication resources, if the detonator module analyzes the message sequence number and the initiation command from the current wireless message, the wireless message sent by the initiator module in the subsequent period is not received.
Before implementing the detonation synchronous control method, a mapping table is pre-constructed, see table 1, wherein each message sequence number in the table corresponds to a first preset time, and the first preset time intervals of adjacent message sequence numbers are consistent.
Table 1 mapping table
| Message sequence number | Detonating countdown |
| 1 | δ×ε×M |
| 2 | δ×ε×(M-1) |
| 3 | δ×ε×(M-2) |
| 4 | δ×ε×(M-3) |
| 5 | δ×ε×(M-4) |
| 6 | δ×ε×(M-5) |
| …… | …… |
| M | δ×ε×1 |
And presetting a detonation time, if the detonation countdown is preset to 0, sending the analyzed detonation instruction to the detonator controller to realize detonation as long as the timing reaches 0.
In a period of time, the detonator module can periodically send wireless messages, at different moments of the period of time, the detonator module receives the wireless messages, the message serial numbers of the wireless messages at different moments are different, different detonation countdown times are given, and then the detonation time can be timed at the same time, so that the detonator module can finish the accurate synchronization of detonation and implement detonation as long as the detonator module receives any frame of detonation instruction and the message serial number, and the problem that the detonation cannot be synchronized under the condition of large wireless communication interference is solved.
Based on the same technical scheme, the invention also discloses a software system corresponding to the method, and a wireless electronic detonator detonation synchronous control system comprises:
the analysis module is used for responding to the received wireless message sent by the initiator module and analyzing the received wireless message; the initiator module periodically transmits a wireless message, wherein the wireless message comprises an initiation instruction and a message sequence number, and the message sequence number i represents the wireless message transmitted in the ith period.
The timing module is used for responding to the analyzed message sequence number and the initiation instruction, acquiring a first preset time corresponding to the message sequence number according to the message sequence number, and timing the first preset time; if the message serial number and the initiation instruction are analyzed from the current wireless message, the wireless message sent by the initiator module in the subsequent period is not received; each message sequence number corresponds to a first preset time; the first preset time interval of the adjacent message sequence numbers is consistent; the first preset time is the preset initiation countdown, and the timing is to count down the initiation countdown.
