Embedded weighing scale protocol converter

Abstract

The invention discloses an embedded weighing scale protocol converter, which comprises a machine cabinet power switch, a weighing protocol converter, a whole-vehicle scale controller and a weighing serial port, wherein the machine cabinet power switch is electrically connected with the weighing protocol converter, the weighing protocol converter is interactively connected with the whole-vehicle scale controller by means of an RS232 serial port, and the weighing protocol converter is interactively connected with the weighing serial port by means of a MyControl MC-B803. The embedded weighing scale protocol converter improves the original method of using a dynamic library for a weighing scale communication protocol and charging software into a method adopting a software-hardware combined protocol converter, effectively solves the problems of crash or instability in the dynamic library loading, calling and the like process, and integrates communication protocols of mainstream weighing scale manufacturers into the protocol converter; and one end of the embedded weighing scale protocol converter is adapted to the weighing scale communication protocol, and the other end is adapted to charging software communication interfaces in different provinces, so that the charging system can acquire data of the weighing scale stably and efficiently.

Description

technical field [0001] The invention relates to the technical field of road traffic, in particular to an embedded weighing scale protocol converter. Background technique [0002] The toll software of domestic highways and ordinary roads adopts the method of communication between the toll software and the manufacturer’s communication protocol to obtain toll data. In order to reduce the workload of toll software modification, the weighing scale communication protocol and the toll software use a dynamic library connection method, which is also The main communication connection mode of the domestic weighing system. Although the design of this method is relatively simple, it is prone to transfer errors and communication failures in actual use, and there are problems of slow protocol loading and poor compatibility. When the road traffic charging unit replaces weighing scale equipment from different manufacturers , It is also necessary to write the corresponding dynamic library an...
