Abstract
An intelligent dynamic weighing device adopts a singlechip as a control core, and adopts data after analog-digital conversion as an input end, a display and a horn as an output end, so as to be used for dynamic weighing for vehicles. The intelligent dynamic weighing device provided by the utility model adopts a weighing sensor to convert pressure signals into weak simulating signals, signals processed by an amplifier and subjected to analog-digital conversion are sent to the singlechip; the processed data taking as a measurement result is sent by the singlechip to the display for displaying, and an alarm is issued in case of overweight. The intelligent dynamic weighing device has a simple structure, is convenient to use, and has excellent dynamic weighing effect.
Description
Technical field
The utility model belongs to electronic sensor and control technology field, is specially a kind of Intelligent Dynamic weighing device.
Background technology
The development of transportation has been played positive impetus to the development of the national economy, but highway in China haulage vehicle overrun and overload phenomenon is very general, and in serious area, all there is overrun and overload behavior in various degree in nearly all goods stock.Satisfy the need Bridge Foundation facility, traffic safety, transport market and vehicle production order of vehicle overload overload transportation caused very big harm.Design detects the vehicle dynamic weighing system that required time is short, accuracy is high, highway communication department is implemented the overrun management effectively, guarantee that the serviceable life of traffic safety, prolongation highway, the aspects such as cost of reduction highway maintenance play vital effect, have significant social benefit and economic worth.
The utility model content
The technical matters that will solve of the present utility model provides a kind of Intelligent Dynamic weighing device.
