Description
[ technical field ] A method for producing a semiconductor device
The invention belongs to the technical field of blasting, and particularly relates to a networking method of an electronic detonator and an electronic detonation system.
[ background of the invention ]
The electronic detonator uses the delay chip to replace chemical delay powder in the traditional detonator, and has the advantages of high delay precision, good safety, network detection and the like. The chip of the electronic detonator stores the ID (Identity document) of each detonator, which can be read by the control device, thereby completing the operations of delayed downloading, detonation and the like. In the actual operation networking process, manual networking is usually adopted, that is, a detonator is connected, and then the ID of the detonator is input into the control equipment in a mode of scanning a two-dimensional code and the like. In the automatic networking, the detonating control equipment is required to automatically acquire the ID of each detonator on the bus, so that an ID searching method is required to search out all detonators on the bus and perform networking. The most straightforward approach is to traverse all IDs, but typically the number of bits of an ID is long and the time required for traversal is very long.
Therefore, there is a need for an improved solution to overcome the above problems.
[ summary of the invention ]
One of the objectives of the present invention is to provide a networking method for electronic detonators and an electronic initiation system, which can obtain the IDs of all electronic detonators on a bus, and implement automatic networking without manual input.
According to one aspect of the invention, the invention provides a networking method of electronic detonators, which comprises the following steps:
the electronic detonator control equipment simultaneously sends an ID reading instruction to each electronic detonator through the bus; after receiving the ID reading instruction, the electronic detonator starts timing; the electronic detonator judges whether the timing time reaches the delay time set by the electronic detonator, if so, the electronic detonator returns a command, and the return command contains the ID of the electronic detonator; if not, the electronic detonator detects whether other electronic detonators start to return instructions or not; if the electronic detonator detects that other electronic detonators start to return instructions, the electronic detonator stops timing; if the electronic detonator detects that the return instruction of other electronic detonators is finished, the electronic detonator continues to time or re-time, and then returns to continuously judge whether the time reaches the delay time set by the electronic detonator or not.
Furthermore, the delay time set by each electronic detonator in the network is different.
Further, the delay time of the electronic detonator is set through a specified storage area inside a chip of the electronic detonator; the delay time of the electronic detonator is generated from the ID of the electronic detonator itself.
Furthermore, the electronic detonator starting return instruction is realized through the electronic detonator pull-down bus; and the electronic detonator returns the instruction to finish the instruction, and the electronic detonator cancels the pull-down bus to finish the instruction.
According to another aspect of the invention, the invention provides an electronic detonation system which adopts the networking method of the electronic detonators, wherein the electronic detonation system comprises an electronic detonator control device, a plurality of electronic detonators and a bus, and the bus is connected with the electronic detonator control device and the plurality of electronic detonators; the electronic detonator control equipment is in bidirectional data communication with the plurality of electronic detonators through the bus, and the electronic detonator control equipment transmits energy to the plurality of electronic detonators through the bus.
Further, the bus is a bidirectional serial data bus.
Compared with the prior art, the method and the device have the advantages that the IDs of all the electronic detonators automatically and orderly return to the electronic detonator control equipment through different response time delays set by each electronic detonator, so that automatic networking is realized.

Wherein:

fig. 2 is a flowchart of a networking method of the electronic detonator in an embodiment of the present invention.
[ detailed description ] embodiments
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic may be included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Unless otherwise specified, the terms connected, and connected as used herein mean electrically connected, directly or indirectly.
Fig. 1 is a block diagram of an electronic initiation system according to an embodiment of the present invention.
The electronic initiation system shown in fig. 1 includes an electronic detonator control device 110, a plurality of electronic detonators 120, and a bus 130, wherein the bus 130 connects the electronic detonator control device 110 and the plurality of electronic detonators 120. The bus 130 may be a twisted pair (or the bus 130 may be a bidirectional serial data bus) that includes a first connection line and a second connection line. The electronic detonator control device 110 performs bidirectional data communication with the electronic detonator 120 through the bus 130, and can also transmit energy to the electronic detonator 120.
In the embodiment shown in fig. 1, only electronic detonators a, B and C of the plurality of electronic detonators 120 are schematically depicted.
Fig. 2 is a flowchart illustrating a networking method of an electronic detonator according to an embodiment of the present invention. The electronic initiation system shown in fig. 1 may adopt the networking method of the electronic detonators shown in fig. 2, so that IDs (Identity documents, i.e. identification numbers) of all electronic detonators are automatically and sequentially returned to the electronic detonator control device, thereby realizing automatic networking.
It should be noted that, when the networking method of the electronic detonator shown in fig. 2 is adopted, the delay time (or response delay time) t set for each electronic detonator 120 is different. In one embodiment, the delay time (or response delay) t set for each electronic detonator 120 may be set using (or by) a designated memory area inside the chip of the electronic detonator 120; it may be generated from the ID of the electronic detonator 120 itself.
The networking method of the electronic detonator shown in fig. 2 comprises the following steps.
And 240, if so, namely if the timing time of the electronic detonator 120 reaches the delay time t set by the electronic detonator 120, returning the instruction by the electronic detonator 120, wherein the return instruction comprises the ID of the electronic detonator.
And step 250, if not, namely if the timing time of the electronic detonator 120 does not reach the delay time set by the electronic detonator, the electronic detonator 120 detects whether other electronic detonators 120 start to return to the instruction.
And 270, if so, namely if the electronic detonator 120 detects that other electronic detonators 120 start to return to the instruction, the electronic detonator 120 stops timing.
In one embodiment, the electronic detonator 120 start return instruction is implemented by the electronic detonator 120 pulling down the bus 130; the return of the electronic detonator 120 to the end of the command is achieved by the electronic detonator 120 cancelling the pull-down bus 130.
Assuming that the electronic priming system shown in fig. 1 is provided with the electronic detonator A, B, C, the delay times (or response delays) t are set to 10ms, 100ms, and 200ms, respectively. When the electronic detonator control device 110 simultaneously sends an ID reading command to the electronic detonator A, B, C through the bus 130, the electronic detonator A, B, C starts timing, wherein the electronic detonator a returns its ID after 10ms first, and pulls down the bus (which indicates a return starting command), and at this time, the electronic detonators B and C immediately stop timing (or stop their return process) after detecting the pull-down condition. The electronic detonator control device 110 will obtain the complete ID of the detonator a. Once the return instruction of the electronic detonator a is finished, the electronic detonators B and C continue to count time or count again, when the timing time of the electronic detonator B reaches 100ms, the electronic detonator B returns the ID of itself on the bus 130 and pulls down the bus (which indicates the start of the return instruction), and at this time, the electronic detonator C immediately stops counting time (or stops the return process of itself) after detecting the pull-down condition. The electronic detonator control device 110 will obtain the complete ID of the detonator B. And by analogy, the ID of the electronic detonator C is obtained finally, so that automatic networking is completed.
In summary, in networking, the electronic detonator control device 110 sends an ID reading instruction to each electronic detonator 120 through the bus 130 at the same time, and then waits for each electronic detonator 120 to return an ID. Each electronic detonator 120 starts timing after receiving the ID reading instruction, and returns its ID when the timing time reaches the delay time (or response delay) t set by the electronic detonator 120. During the process from the beginning of the timing of each electronic detonator 120 to the delay time (or response delay) t set by the electronic detonator 120, the electronic detonator 120 will continuously detect the bus 130, and once another electronic detonator 120 starts to return a command (or return signal), the electronic detonator 120 stops its timing and command return process. Once the return command on the bus 130 is over, the electronic detonator 120 continues to count or count again, and returns its ID when the counted time reaches the delay time (or response delay) t set by the electronic detonator 120. That is, once one of the electronic detonators 120 starts to return to the command, the other electronic detonators 120 do not continue to respond to the ID read command, and thus the electronic detonator control device 110 can obtain the ID of the first responding electronic detonator 120. After the return instruction of the electronic detonator 120 is finished, all other electronic detonators 120 which do not return instructions continue to time or re-time, and the above process is repeated until the electronic detonator control equipment 110 acquires the IDs of all the electronic detonators 120, thereby completing the whole automatic networking process. Thus, the present invention can automatically and orderly return the IDs of all the electronic detonators 120 to the electronic detonator control device 110, thereby realizing automatic networking.
In the present invention, the terms "connected", "connecting", and the like mean electrical connections, and mean direct or indirect electrical connections unless otherwise specified.
It should be noted that those skilled in the art can make modifications to the embodiments of the present invention without departing from the scope of the appended claims. Accordingly, the scope of the appended claims is not to be limited to the specific embodiments described above.
