The system can realize the measurement of temperature, also can realize the control of temperature...

Analysis of the electro hydraulic grab's not tightly closed fault were conducted by using fault tree, through analyzing of the working principle, establishing the fault tree, gradual layered investigation, so as to quickly find the source of the fault and repair the grab. Practices have proved that the...

With the development of science and technology, the industry demand for temperature and humidity is increasing day by day. In this paper, a design of temperature and humidity collection system based on ARM is put forward. The system is designed by combining a ZigBee technology and GSM technology with...

In this paper, a measurement control circuit is designed on collision information from vibrating rod which is furnace wall collision transmission device. Through measuring the amplitude, frequency and attenuation ratio of the collision, we can preliminary judge whether the material impacts the inner...

Laser ranging is a widely used laser technology. It has many advantages, such as convenient operation, high precision, and the ability to use it anytime and anywhere. In this paper, a portable laser ranger based on STM32 is designed, which can perform high-precision ranging function under complicated...

In this paper, in order to obtain performance of marine natural gas/diesel dual fuel engine on exhaust gas recirculation (EGR), the AVL-FIRE software had been adopted to numerical effect analyze of different EGR on combustive process and emission of the engine. The result shows that numerical simulation...

In this paper, forklift scheduling management device was designed. The workers can quickly find the right position according to the demand of the forklift, so that the forklift could achieve accurate and efficient scheduling, to prevent sabotage and empty air forklift. And the forklift could work with...

In the study, the AVL-FIRE software had been adopted to numerical effect analysis on combustive process of the engine. The result shows that numerical simulation results are consistent with the tested pressure, ignition point of ignition diesel is 2 ø CA ATDC, ignition point of natural gas is 2.25 ø...

In order to adapt to the demand of sample treatment before experiment, this paper designed a three axis based on motion control card and VB sample control system. The system takes the motion control card as the core, stepping motor as the actuator, and VB operating system on the movement control CARDS...

Most of the logistics companies use manual sorting method to complete the sorting work. However, with the rapid development of commodity economy, there is a trend that the demands direction of development towards small volume and species. With the increased species and large quantity of commodities,...
