Measuring and computing complex “Hydrofracturing” is mobile and aimed for determination of acting in solid stresses by method of measuring hydraulic fracturing. In the paper, approaches to re-equipment of the complex considering actual requirements to the applied underground equipment and possibilities of modern microprocessing facilities, are justified. New software and hardware solutions and functioning features of portable pressure recorder are considered based on microprocessing system of conversion analog signal coming from pressure sensor and control signal of battery voltage of autonomous device for experiment operating. Spark safe method of switching of electronic scheme of the device is proposed where there is reed switch of supply circuits with scheme of smooth start. It prevents fritting of the reeds. It is proposed to apply wireless scheme of charging of inside battery. Absence of detachable connections in structure of the portable pressure recorder prevents negative impact of high humidity in the atmosphere coal and ore mines on its functioning. Also, it excludes the possibility of spark formation. |
