Abstract
A wireless electronic detonator includes an energy source and functional modules. A first switching switch is provided between the energy source and the functional modules, making it possible to connect or not connect the energy source to the functional modules. A control module for controlling the first switching means includes a module for recovering radio energy configured to receive a radio signal from a control console, to recover the electric energy in the radio signal received, to generate an energy recovery signal (VRF) representative of the level of electric energy recovered, and to generate as output a control signal (VOUT) as a function of the recovered energy, the control signal controlling the first switch.
Claims25
A wireless electronic detonator comprising:
- an energy source;
- functional modules;
- a first switch between the energy source and the functional modules, and operative to connect or not to connect the energy source to the functional modules;
- and
- a control module that controls the first switch, the control module comprising a radio energy recovery module configured to:
- receive a radio signal coming from a control console,
- recover electrical energy in the received radio signal,
- generate an energy recovery signal (VRF) representing the level of recovered electrical energy, and
- generate a control signal (VOUT) according to the recovered electrical energy, the control signal (VOUT) controlling the first switch.
A method of activating a wireless electronic detonator comprising an energy source, functional modules and a first switch between the energy source and the functional modules and that are controlled by a control module, the method comprising:
- receiving a radio signal,
- recovering electrical energy from the received radio signal,
- generating an energy recovery signal (VRF) representing a level of energy recovered, and
- generating a control signal (VOUT) according to the recovered energy, the control signal (VOUT) controlling the first switch so as to connect the energy source to the functional modules.
The method according to, wherein the verification comprises comparing the level of the energy recovery signal (VRF) representing the level of recovered electrical energy with an energy threshold value (Vthreshold), the first switch being operated so as to maintain the energy source connected to the functional modules when a level of the energy recovery signal (VRF) is greater than or equal to the energy threshold value (Vthreshold).
