the invention provides a micro-power consumption wireless drilling pump stroke detection device, which comprises:
the device comprises a microcontroller, a Hall element, a communication module and an energy storage mechanism;
the energy storage mechanism is used for supplying power to the microcontroller, the Hall element and the communication module;

Preferably, the chip of the microcontroller is C8051F912, and the hall element signal is MT 1321A.
Furthermore, the acquisition processing of the pump speed is carried out under the condition that the power consumption is reduced to the maximum extent and the detection precision requirement is met, the cycle of the pump speed is calculated by taking a high-precision 32768Hz time-base signal provided by a DS3231N chip as a reference (the cycle is calculated by calculating the number of occupied time-base signals), and then the pump stroke is calculated by a formula of 60000000 pump speed cycle/transmission ratio.
Preferably, the energy storage mechanism is a storage battery.
Example two:
the invention provides a micro-power consumption wireless drilling pump stroke detection method, which is applied to a microcontroller and comprises the following steps:
