Vehicle-mounted intelligent dynamic weight monitoring device, method and system

Abstract

The invention relates to a vehicle-mounted intelligent dynamic weight monitoring device, method and system. The device is composed of a wireless positioning device, a processor, a temperature acquisition device, and a weight acquisition device. The weight acquisition device collects a loading signal of a monitored vehicle; the temperature acquisition device collects a temperature signal at the weight acquisition device; the processor obtains a loading value and a temperature value based on the loading signal and the temperature signal and sends the temperature value and the corrected loading value, together with positioning information, to a server by the wireless positioning device. Because the processor is arranged at a vehicle, accurate temperature values and loading values can be sent to the server by a base station continuously and seamlessly during the process of driving away from a place of departure and arriving at a destination by the vehicle; and with the position information, all-weather monitoring a vehicle-mounted weight can be realized. Meanwhile, the temperature acquisition device is arranged to obtain the temperature at the weight acquisition device, so that the weight acquisition device can work at a proper temperature all the time and thus accuracy of the loading value is improved.

Description

technical field [0001] The invention relates to the monitoring field, in particular to a vehicle-mounted intelligent dynamic weight monitoring device, method and system. Background technique [0002] At present, the common way of supervising and checking is to set up special-purpose vehicle weighbridges at toll intersections, which has defects such as large equipment investment costs, poor flexibility, and easy missed inspections. With the popularization of wireless positioning technology, many companies are trying to place weighing components on vehicles and transmit weight data in real time through wireless positioning devices, but weight data is extremely difficult to obtain dynamically, and the accuracy and repeatability are extremely poor. There are also discontinuity, misinformation, and packet loss in data transmission. So far, there is no mature and stable vehicle-mounted intelligent dynamic weight monitoring product on the market.

[0002] At present, the common method of supervising and checking is to set up special-purpose vehicle weighbridges at toll intersections, which has defects such as high equipment investment costs, poor flexibility, and easy missed inspections.

With the popularization of wireless positioning technology, many companies are trying to place weighing components on vehicles and transmit weight data in real time through wireless positioning devices, but weight data is extremely difficult to obtain dynamically, and the accuracy and repeatability are extremely poor. There are also discontinuities, miscommunication, and packet loss in data transmission. So far, there is no mature and stable vehicle-mounted intelligent dynamic weight monitoring product on the market.

The traditional way to obtain the vehicle load is to weigh the vehicle twice. The driver first drives the empty vehicle to the platform to obtain the weight of the vehicle, and then the driver drives the vehicle to the loading point for loading, and the fully loaded vehicle Drive again to the weighbridge to obtain the weight of the vehicle at this time. The whole process involves two weighings, two manual operations by the weighbridge personnel and one manual calculation, which not only easily causes blockage around the weighbridge, but also is prone to mistakes
