Detailed Description
The embodiments of the present invention will be described with reference to the accompanying drawings and preferred embodiments, and other advantages and effects of the invention will be easily understood by those skilled in the art from the disclosure in the specification.
The present invention can also be implemented or applied through other different specific embodiments, and various details in the present specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are for purposes of illustration only and are not intended to limit the scope of the present invention.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic concept of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the form, amount and ratio of the components in actual implementation may be changed at will, and the layout of the components may be more complicated.
As shown in fig. 1, an initiator cascade control initiation device includes: the main engine detonation module is connected with a plurality of extension detonation modules; the extension detonation module is connected with a plurality of electronic detonators 1.
The host detonation module is connected with a plurality of extension detonation modules in a cascade mode through a CAN bus.
The host detonation module is cascaded or connected in parallel through the CAN bus 2 to realize cascade detonation. The cascade detonation refers to that one detonator is used as a host detonator and can control a plurality of extension detonators, and the extension detonators control a plurality of electronic detonators to detonate. The cascade connection of the initiators can solve the problem of insufficient loading capacity of large-scale blasting operation. Meanwhile, the distance between the operation detonation site and the detonation point can be prolonged by controlling the detonation in a cascade manner, for example, in the process of blasting in a tunnel or a well, the detonation control point can be prolonged to the surface or the tunnel mouth by controlling the detonation through a cascade extension control line. In addition, through cascade detonation, long-delay detonation can be realized. The electronic detonator generally stores electric energy through a small capacitor, the electric energy can be provided for the chip to continuously work for a period of time under the condition that a detonating bus is broken, after the delay time is up, the residual electric energy of the capacitor provides ignition energy, and the energy stored by the capacitor is very limited and can only provide short-time power supply capacity. And each extension detonator can set independent delay time, after the host detonator sends a detonation instruction, the extension detonators start to delay, after the extension detonators reach the delay time, the detonation instruction is sent to the electronic detonators through the detonation buses, and the electronic detonators perform corresponding delay detonation according to the set delay time. The total delay time is equivalent to the delay of the extension detonator plus the delay of the electronic detonator, so that the initiation delay time can be greatly prolonged, and the requirement of long-delay initiation is met.
The plurality of extension detonation modules are connected in parallel.
The extension detonation module is connected with a plurality of electronic detonators 1 through a bus 3.
The host detonation module is a host detonator 4. The host detonator is operated to finish the detonation operation, the problem that the operation time of a plurality of detonators is not synchronous is avoided, all control instructions are sent out through the host detonator, and the detonation work can be finished only by operating the host detonator in the cascade detonation control stage.
The number of the main machine exploder connected with the branch explosion modules is less than or equal to 20.
The extension detonating module is an extension detonator 5. In a large-scale blasting environment, the problem that the loading capacity of a single detonator is not enough due to the cooperative operation of a plurality of detonators can be solved. The extension detonator can set the delay time of delay detonation, and the delay of the extension detonator can be set to realize the long-delay detonation under the condition that the delay length of the electronic detonator cannot meet the long delay.
The number of the electronic detonators 1 carried by the single extension initiator 5 is less than or equal to 400.
And the system also comprises a software/hardware system for controlling the host detonation module and the extension detonation module. The main machine detonator and the extension detonator adopt bidirectional traffic, and the main machine detonator can monitor the state of the extension detonator in real time and display the state on an LCD screen of the main machine detonator. The battery electric quantity, the number of registered electronic detonators, the number of online electronic detonators, the link and the step of operation of the branch machine detonator can be monitored in real time on the host machine detonator.
The utility model provides an exploder cascade control priming device, the priming method in the actual operation process does: firstly, the host detonator and the extension detonators share one software/hardware system, and the role switching can be realized only by entering different function pages, so that the field operation equipment management is facilitated; secondly, in a large-scale detonation operation environment, the problem that the loading quantity of a single detonator is insufficient can be solved by cascading under the condition that the quantity requirement cannot be met by the single detonator; then, the distance between the operation detonation site and the detonation point can be prolonged by controlling the detonation in a cascade manner; and finally, the long-delay detonation can be realized through the cascade detonation, so that the requirement of the long-delay detonation is met, and the method has popularization and application values in a large-scale detonation operation environment.
