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

Example Embodiment
[0026] The specific implementation of the present invention is as follows:
[0027] (1) When the data of the weighing instrument is less than the set value, it is judged to be the empty scale state, and the traffic light signal is controlled to prompt the passage; when the state changes from other states to this state, the corresponding event is triggered and the manual trigger function is reserved;
[0028] (2) When the weighing instrument data is greater than the set value, and the infrared (grating) in front of the scale is blocked, it enters the weighing state, and the vehicle number recognition is activated at the same time, and the traffic light prompt is changed; when the state changes from other states to this state, trigger Corresponding events and reserve manual trigger function;
[0029] (3) When the weighing instrument data is greater than the set value, and the infrared (grating) before and after the scale is not blocked, it enters the full scale state and starts the sta...

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...
