Multifunctional simulation test device and method for control system of road machinery products

Abstract

The invention discloses a multifunctional simulation test apparatus for a pavement construction machinery product control system. The test apparatus comprises an operating console, and a multi-simulation-signal and switch-signal generator, a display screen, a signal input interface and a signal output interface which are installed on the operating console, wherein the signal output end of the signal input interface is connected with the signal input end of the display screen, the signal input end of the signal input interface is connected with the signal output end of a controller of the pavement construction machinery product control system; the signal output end of the multi-simulation-signal and switch-signal generator is connected with the signal input end of the signal output interface, and the multi-simulation-signal and switch-signal generator comprises a voltage signal generation unit, a current signal generation unit, a waveform signal generation unit, a PWM signal generation unit and a switching quantity signal generation unit; and the signal output end of the signal output interface is connected with the signal input end of the controller. The invention also discloses a test method.

Description

technical field [0001] The invention belongs to the technical field of pavement engineering machinery manufacturing, and in particular relates to a multifunctional simulation test device and a test method for a control system of pavement machinery products. Background technique [0002] Pavement construction machinery is a kind of machinery used to build roads, urban roads and airport pavements. There are many types of pavement machinery products, which are usually divided into four categories: earth pavement construction machinery, gravel pavement construction machinery, asphalt concrete pavement construction machinery and cement concrete pavement paving machinery. Among them, the soil road construction machinery is mainly the stabilized soil mixing machine, which is usually used to loosen the soil, mix it with a stabilizer and mix it evenly to make stabilized soil, and then pave and compact it to form a soil road ( foundation); gravel pavement construction machinery is ma...

Problems solved by technology

[0004] However, since pavement machinery products involve paver, milling machine, grader, asphalt mixing equipment, factory mix, cement paver, etc., different pavement machinery products correspond to different controllers. The output signals will be different, so the current prior art usually uses different test devices to test the controllers of different road machinery products to meet the signal requirements of the controllers of different road machinery products, such as the mixing equipment disclosed in CN104864963A The temperature and current test device can only be used to test the performance of the controller of the mixing equipment; the test system and method for the center of mass and amplitude uniformity of the steel wheel of the road roller disclosed in CN102798500A can only be used to test the equipment performance of the controller of the road roller

Obviously, this kind of testing method of designing different testing machines for each type of road machinery product has high testing cost and time-consuming, which affects the delivery time of road machinery products
