Signal centralized control method of truck scale

Abstract

The invention relates to a signal centralized control method of a truck scale and belongs to the technical field of truck scale control. The method comprises steps of dividing key points related to truck scale metering service processes into following states: empty, loading, all loaded, vehicle stably stopping, to-be-confirmed, to be stored and vehicle unloading; carrying out centralized displaying and packaging on the truck scale and auxiliary device, wherein in the automatic metering process, through calling displaying, the reuse rate is improved; and determining the key points of each truck scale metering service process, and determining main weighting process for leaving the truck scale through all auxiliary devices, thereby reducing the coupling degree. According to the invention, through united control and scene setting of each related signal, the method can be automatically suitable for all kinds of actual applications and independently finishing process control of the key node. Meanwhile, through the plug-in design, the application cost is greatly reduced, the stability and safety are improved and the development period is shortened.

Description

technical field [0001] The invention relates to a centralized control method for truck scale signals, belonging to the technical field of truck scale control. Background technique [0002] At present, in order to realize the automatic weighing of truck scales, many auxiliary equipment are often needed, such as infrared (grating), radio frequency vehicle number recognition, video, IC card, voice intercom, barrier gate, large screen, traffic lights, printers, etc. These auxiliary equipment and The weighing instrument cooperates to complete the automatic weighing of the vehicle and prevent various cheating situations. However, in the actual application process, due to different construction conditions, the vehicle number recognition and the control of barrier gates and traffic lights are divided into control before, during and after the pound. There are big differences in various control methods. At the same time, auxiliary equipment It is also possible to use only a few of th...

Problems solved by technology

However, in the actual application process, due to different construction conditions, the vehicle number recognition and the control of barrier gates and traffic lights are divided into control before, during and after the pound. There are big differences in various control methods. At the same time, auxiliary equipment It is also possible to use only a few of them, resulting in different control methods for truck scale signals.

Therefore, at present, the signal control of various truck scales often adopts a separate control method. In this control method, many signal content with similar control methods need to be repeatedly written, and once a certain signal is added / removed or a certain auxiliary equipment is moved position, it is necessary to greatly adjust the control methods of other signals, resulting in a large amount of process change costs

However, these control signals, as an auxiliary means of automatic weighing, consume a lot of cost resources in the actual implementation process, and as the follow-up maintenance continues to be complicated, it will increase the maintenance cost

This method of independent control and mutual cooperation of signals cannot realize the centralized control of various signals of the truck scale and make them independent of the business process. The key points related to the business process are not highly highlighted, and the coupling with the business process High precision, low reuse rate, greatly increased implementation and maintenance costs
