System and method for monitoring rotary drilling machine

Abstract

The invention relates to the field of remotely-monitored industrial machines, in particular to a system and a method for monitoring a rotary drilling machine. The system comprises a vehicle-mounted rotary drilling machine monitor, and is characterized in that: a central processing unit (CPU) of a vehicle-mounted controller is arranged on the rotary drilling machine; and the vehicle-mounted controller is used for acquiring sensing information, position information and commands of a server terminal of a remote monitoring management center manufacturer, setting operation parameters, monitoring operation states, transmitting inquiry commands and controlling cathode ray tube (CRT) display of a screen in a vehicle-mounted mode. The monitoring method comprises the following steps of: starting an engine; switching on a power supply; starting the monitoring of the CPU; operating a rotary encoder, a depth sensor, an inclination sensor, a pressure sensor or a monitoring sensor input information device; and transmitting a digital analog signal to a CPU data acquisition device through an input / output (I / O) interface. By the system and the method, the development period and the stable period of a product are shortened; and the current advanced communication technology is deeply developed through a master control system which is completely autonomously researched and developed, so that the system and the method have favorable practical application.

Description

[technical field] [0001] The invention relates to the field of remote monitoring industrial machinery, in particular to a monitoring system and method for a rotary drilling rig. [Background technique] [0002] Rotary drilling rig is a construction machine suitable for hole-forming operations in building foundation engineering. It is mainly suitable for the construction of sandy soil, cohesive soil, silty soil and other soil layers. It is widely used in various foundation constructions such as cast-in-place piles, diaphragm walls, and foundation reinforcement. The rated power of rotary drilling rigs is generally 125-450kW. The output torque is 120-400kN m, the maximum hole diameter can reach 1.5-4m, and the maximum hole depth is 60-90m, which can meet the requirements of various large-scale foundation construction. [0003] Same as traditional construction machinery, the current rotary drilling rig mainly uses local pointer indication, which is similar to the car's oil level...

Problems solved by technology

In addition, due to the limited display data of black and white LCD and simple color screen, a large amount of monitoring data cannot be displayed at one time

In addition, some manufacturers install GPS positioning devices or data acquisition devices or timing lockers on rotary drilling rigs to achieve data feedback and shutdown control of rotary drilling rigs, but these devices often have single functions, high economic costs and gimmicks. rough question
