Problems solved by technology

In order to realize the function of driving the hydraulic unit, a large number of high-reliability and high-temperature performance chips are used in the hydraulic drive module, but the hydraulic drive module is affected by factors such as technology and chip quality during the production process. Defects cannot be exposed in the conventional test environment, but they will appear in the high temperature and vibration environment, which directly affects the reliability of the instrument.
The traditional manual test method has a large workload, less data records, and cannot be continuously monitored, which affects the comprehensiveness and reliability of the test

Abstract

The invention discloses a test system. The test system involves a main control module, distributed control modules and test subsystems, wherein the main control module is connected with one or more distributed control modules; test subsystems involve data acquisition modules, analog load modules, signal simulation modules, to-be-tested drive modules and motors, and the to-be-tested drive modules are used for driving the motors to operate; distributed control modules are connected with all the modules in test subsystems so as to control all the modules to operate; data acquisition modules are used for acquiring measurement data of the to-be-tested drive modules and transmitting the measurement data to the distributed control modules; the analog load modules are used for transmitting torqueloads for the motors of the to-be-tested drive modules according to first instructions of the distributed control modules; and the signal simulation modules are used for outputting simulation pressuresignals to the to-be-tested drive modules according to second instructions of the distributed control modules. The test system can be used for comprehensively screening out the to-be-tested drive modules under the underground severe environment.

Description

technical field [0001] The present application relates to but is not limited to the technical field of rotary steerable drilling equipment testing, and in particular relates to a testing system related to a rotary steerable hydraulic drive module. Background technique [0002] The rotary steerable drilling system is an automatic drilling system that realizes wellbore trajectory control in the state of rotary drilling. Compared with traditional slide-steering drilling, this technology has the characteristics of high mechanical speed, high precision of wellbore trajectory control, and good borehole purification effect, and can meet the requirements of difficult special process steering such as horizontal wells, extended-reach wells, and three-dimensional multi-target wells. Drilling needs. At present, the rotary steerable drilling technology has been widely used in oil exploration, development and production all over the world, and its mainstream design methods include static...
