Description
Technical Field
The utility model relates to a high-speed weighing system of narrow strip formula, specifically speaking, the utility model relates to a high-speed weighing system of preset narrow strip of batch production.
Background
At present, truck overload phenomena are common in China, and in order to control the truck overload phenomena on expressways, high-speed dynamic weighing systems are installed on expressways with serious overload phenomena to carry out dynamic weighing detection. The weighing devices used by the existing high-speed dynamic weighing system comprise a narrow-strip high-speed weighing device, a flat-plate high-speed weighing device and a piezoelectric type weighing device.
Piezoelectric type weighing device installation is convenient, construction volume is little, but receives factors such as vehicle speed of traveling to influence great, and measurement accuracy is lower. The flat plate type weighing device has higher measurement precision when a vehicle runs at low speed, but when the running speed of the vehicle is more than 60km/h, the measurement precision is low because the area of a weighing table-board is too large and the deformation recovery speed of the table-board is slow, and the flat plate type weighing device has longer installation construction period and long circuit breaking time. The narrow-strip type high-speed weighing device is widely applied due to the small area of the weighing table top, the quick deformation recovery, the sensitive response and the relatively high measurement precision.
The common narrow strip type high-speed weighing device comprises a weighing table top, a plurality of weighing sensors arranged below the weighing table top, a coil type vehicle separator buried under the road surface and a data processing unit. After each axle of the vehicle passes through the weighing table board in sequence, the weighing sensor collects weighing signals of the vehicle, the data processing unit performs A/D conversion and filtering processing on the received weighing signals to further calculate the weight of each axle, and then calculates the weight of the whole vehicle.
The length of a weighing table top of the narrow-strip high-speed weighing device is only about 10cm (the width of the weighing table top is consistent with the width of a lane), the contact area between tires of a travel vehicle and the weighing table top is small, one part of the tires are pressed on the weighing table top, and one part of the tires are pressed on a road surface to support the road surface, so that the conventional narrow-strip high-speed weighing device is incomplete weighing, does not belong to effective complete weighing, needs a data processing unit to perform weight compensation calculation, determines weighing precision by calculation accuracy, and is low in reliability of a measuring result particularly for an abnormally-running vehicle or a modified irregular vehicle through one-time weighing and calculation.
In order to further improve the accuracy and reliability of the measurement result of the narrow strip type high-speed weighing device, the inventor tries to arrange two narrow strip type high-speed weighing devices on an expressway at intervals, when the same tire of the same vehicle passes through the two narrow strip type high-speed weighing devices respectively, the contact area between the tire and two weighing table boards is different, the weighing results are different, the data processing unit has deviation through supplementary calculation results, and the final result obtained through twice calculation and averaging is more accurate and closer to the true value.
However, two adjacent narrow strip type high-speed weighing devices are installed on the highway at intervals, the requirement on the construction environment is high, the weighing table tops of the two narrow strip type high-speed weighing devices are required to be on the same horizontal plane, the road surfaces between the two weighing table tops and the two weighing table tops are required to be on the same horizontal plane, jolting cannot occur, and otherwise the measuring accuracy is seriously influenced. The installation level requirement for constructors is also high. In addition, the requirement on the construction period is strict, the construction period can not exceed 72 hours, and the highway can not be broken for a long time to influence the traffic.
