Abstract
The detonation of one or more explosive charges and propellant charges by a detonator in response to a fire control signal from a command and control system comprised of a command center and instrumentation center with a communications link therebetween. The fire control signal is selectively provided to the detonator from the instrumentation center if plural detonation control switches at the command center are in a fire authorization status, and instruments, and one or more interlocks, if included, are in a ready for firing status. The instrumentation and command centers are desirably mobile, such as being respective vehicles.
Claims14
An apparatus for controlling the detonation of an explosive by a detonator comprising:
- a movable command center;
- the command center comprising at least one manually controlled switch operable to produce a first fire authorization signal when said at least one switch is in a detonate explosive position;
- the command center comprising command center computing hardware configured to cause the generation of a second fire authorization signal in response to actuation of displayed fire command switch to a detonate explosive position;
- a movable instrumentation center physically spaced from and movable relative to the movable command center;
- the instrumentation center comprising fire setting and control system (FSCS) computing hardware having an output for coupling to the detonator and configured to selectively provide a fire control signal to cause detonation of the detonator and explosion of the explosive;
- the FSCS computing hardware also comprising plural inputs coupled to a plurality of instruments for receiving instrument status signals corresponding to the operational status of such instruments and instrument data signals corresponding to data signals from such instruments;
- wherein the FSCS computing hardware is configured to selectively provide a fire control signal to cause the detonation of the detonator to detonate the explosive in response to the first and second fire authorization signals providing that the status of the instruments determined based on the instrument status signals is acceptable for detonating the explosive;
- a communication network operable to communicate signals from the command center to the instrumentation center and from the instrumentation center to the command center, such communicated signals corresponding to the first and second fire authorization signals, corresponding to the instrument status signals and corresponding to the instrument data signals;
- and
- the FSCS computing hardware and command computing hardware being configured to test the operability of the communication network and to prevent the detonation of the detonator and explosion of the explosive in the event the communication network is determined to be inoperative.

A method of controlling the firing of an explosive comprising:
- (a) placing a command center a first distance away from the site at which the explosive is to be detonated;
- (b) placing an instrumentation center a second distance away from the site at which the explosive is to be detonated, the second distance being less than the first distance;
- (c) establishing a communication link between the command center and instrumentation center and verifying the operation of the communications link at least during times that the explosive may be detonated;
- (d) receiving instrument status signals at the instrumentation center indicating the operational status of plural instruments and transmitting signals corresponding to such instrument status signals to the command center;
- (e) receiving at least one interlock status signal at the instrumentation center indicating the status of the at least one interlock and transmitting signals corresponding to such interlock status signal to the command center;
- (f) providing plural fire authorization signals from the command center to the instrumentation center;
- (g) selectively delivering a fire control signal from the instrumentation center to an explosive detonator in response to the plural detonation control signals and providing that the instrument status signals and interlock status signals indicate that the instruments and at least one interlock are in an acceptable status for the explosive to be detonated;
- (h) detonating the explosive in response to the fire control signal;
- and
- (i) receiving explosion responsive instrument data signals at the instrument center collected by instruments in response to the explosion and transmitting signals corresponding to the instrument data signals to the command center.
