Method used for garbage dynamic weighing of sanitation truck

Abstract

The invention relates to the field of garbage weighing, and relates to a method used for garbage dynamic weighing of a sanitation truck. A weight sensor and a dip angle sensor are arranged on a supporting frame, and the sanitation truck is provided with a processor which is connected with the weight sensor and the dip angle sensor. One second after a garbage barrel lifts, during the period when the rotation angle of the garbage barrel around the supporting frame is 1-20 degrees, a weight sensor collects weight data, the dip angle sensor collects supporting frame overturning angle data at the same time, the processor collects data of the weight sensor and the dip angle sensor, a dynamic waveform displaying the change of the weight with the change of the location and time is drawn, and through a method for calculating the waveform average value, the weight value of lifted garbage at this time is calculated. According to the method, when the garbage weighing efficiency is greatly improved, the weighing result is basically accurate, and the weighing requirement of the sanitation truck is met.

Description

technical field [0001] The invention relates to the field of garbage weighing, in particular to a method for dynamically weighing garbage of a sanitation collecting and transporting vehicle. Background technique [0002] In recent years, with the advancement and development of urban-rural integration and the popularization and promotion of Internet of Things technology, the construction of smart cities has gradually been put on the agenda. As an important part of smart city construction, smart sanitation has become more and more popular. . However, smart sanitation requires a clear smart sanitation management index system to guide and evaluate the construction of smart sanitation in various places, such as designing garbage collection modes, transportation modes, and disposal modes based on population, area, and natural conditions. Smart sanitation, relying on Internet of Things technology and mobile Internet technology, conducts real-time management of the whole process of...

Problems solved by technology

Static weighing: Generally, the vehicle is driven to a special weighbridge for weighing; the advantage is that the measurement is accurate, but the disadvantage is that the one-time investment is large, and on-site settlement cannot be carried out, and the reloading volume cannot be monitored and dispatched in real time

Dynamic weighing, such as the patent application number 201510582848.4, uses a proximity switch in the weighing area, and the detection distance is 10-15mm. When the signal is sensed, it will stop for a few seconds to weigh. The advantage is that compared with weighing on the weighbridge, It solves the inability to carry out on-site settlement, and cannot monitor and dispatch the reloading volume in real time. It is still static weighing in essence. The shortcomings are: 1. The proximity switch is easily deformed and damaged by impact; 2. After a long time, with the bucket The wear and tear of the mechanism will easily lead to the deviation of the sensing position of the proximity switch; 3. There must be a pause during each dumping process, which will reduce the work efficiency and cause complaints from users; In vibration, the sensor and weighing method designed according to static weighing will easily lead to inaccurate measurement; probably just a fraction of the actual weight of the trash can

In short, due to the influence of the above-mentioned various uncertain environmental factors, the existing dynamic weighing scheme is actually difficult to guarantee the accuracy of weighing
