[ 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 detonation 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 method for detecting signals between electronic detonators according to an embodiment of the present invention. The electronic detonation system shown in fig. 1 can adopt the signal detection method between electronic detonators shown in fig. 2 to realize return signal detection between electronic detonators and avoid the problem of bus response conflict.
The method for detecting signals between electronic detonators shown in FIG. 2 includes the following steps.
At step 210, an electronic detonator 120 (e.g., electronic detonator a) sends a return signal to the bus 130.
In step 220, the electronic detonator control device 110 detects a return signal of the electronic detonator 120 (e.g., electronic detonator a) via the bus 130.
And 240, detecting the amplified return signal of the electronic detonator 120 (for example, the electronic detonator A) by other electronic detonators (for example, the electronic detonator B and the electronic detonator C) and stopping responding in time.
In a preferred embodiment, the electronic detonator 120 of the present invention generates a pull-down signal via the pull-down bus 130, which serves as a return signal for the electronic detonator 120. Generally, the pull-down capability of the electronic detonator 120 is weak, and the pull-down capability of the electronic detonator control device 110 is strong. Thus, the electronic detonator 120 may detect the pull-down signal of the electronic detonator control device 110, but not the pull-down signals of the other electronic detonators 120. After detecting the weak pull-down signal of the electronic detonator 120 (e.g., the electronic detonator a), the electronic detonator control device 110 of the present invention strongly pulls down the bus 130 to amplify the weak pull-down signal of the electronic detonator 120 (e.g., the electronic detonator a), so that other electronic detonators (e.g., the electronic detonator B and the electronic detonator C) detect the amplified weak pull-down signal of the electronic detonator 120 (e.g., the electronic detonator a), and timely stops responding to prevent signal return collision between the electronic detonators 120.
Fig. 3 is a timing diagram of a pull-down signal generated by the electronic detonator and a pull-down signal generated by the electronic detonator control apparatus according to an embodiment of the present invention. Wherein 310 represents a weak pull-down signal generated by the electronic detonator 120 (or a return signal of the electronic detonator 120); indicated at 320 is a strong pull-down signal generated by the electronic detonator control apparatus 110. As can be seen from fig. 2, the return signal of the electronic detonators 120 is weak, and the electronic detonator control device 110 immediately performs a strong pull-down on the bus 130 upon detecting that one electronic detonator 120 starts the return signal 310, so that the other electronic detonators 120 can immediately stop responding after detecting the strong pull-down signal 320, thereby preventing signal return collision between the electronic detonators.
In summary, when the electronic detonator control device in the invention detects the return signal of the electronic detonator, the electronic detonator control device amplifies (or strengthens) the return signal of the electronic detonator on the bus, so that other electronic detonators can detect the amplified return signal of the electronic detonator, and the response is stopped in time, thereby preventing signal return collision between the electronic detonators.
In the present invention, the terms "connected", "connecting", and the like mean electrical connections, and direct or indirect electrical connections unless otherwise specified.
It should be noted that those skilled in the art will be able to 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.
