Abstract
A detonator includes a substrate, a controller mounted to the substrate, and a sensor coupled to the controller to measure a temperature, pressure, acceleration or other environmental info and/or electrical status of the internal electronics of the detonator. The controller is configured to store the measured environmental parameter and/or electrical status in a memory of the detonator, transmit the stored data from the detonator to a remote master controller, execute an action in response to a value of the measured environmental parameter, and/or prevent or modify at least one detonator function in response to the data obtained.
Claims21
An electronic detonator, comprising:
- a substrate;
- a controller mounted to the substrate;
- a memory coupled to the controller;
- and
- a sensor coupled to the controller and configured to make multiple readings of a temperature, a pressure, or an acceleration;
- wherein the controller is configured to store an environmental parameter measured by the sensor in the memory.
An electronic detonator, comprising:
- a controller;
- a sensor coupled to the controller;
- and
- a memory coupled to the controller;
- the controller is configured to store an electrical status of the detonator in the memory at multiple steps of a blast, including a power up step, a verify step, and arming step, a calibration step, and a firing step.
