Material transport vehicle and unloading monitoring device thereof

Abstract

The invention discloses a material transport vehicle and an unloading monitoring device thereof. The unloading monitoring device comprises a monitoring center, a vehicle-mounted detector, a vehicle-mounted positioning device and an information transmitting network, wherein the monitoring center is provided with a remote visible commanding and monitoring management platform and can be used for receiving signals and feeding back solution measures in real time; the vehicle-mounted detector is used for detecting the motion states of a cargo box body and / or carried materials of the material transport vehicle; the vehicle-mounted positioning device is arranged on the material transport vehicle, is connected with the vehicle-mounted detector and is used for receiving and processing signals sent by the vehicle-mounted detector and feeding the signals back to the monitoring center; and the information transmitting network is used for realizing the interactive communication between the vehicle-mounting positioning device and the monitoring center. The unloading monitoring device disclosed by the invention can be used for monitoring a material transport process to achieve the purposes of standard operation of working vehicles, benefit increase and overall planning and management.

Description

technical field [0001] The invention relates to a material discharge monitoring device, in particular to a material transport vehicle and a material discharge monitoring device thereof. Background technique [0002] At present, the anti-stealing measures for material transport vehicles on the market can be basically divided into two types. Take concrete mixer transport vehicles as an example: [0003] 1. Manual monitoring measures. When the cement output of the mixing plant and the demand of the construction company frequently conflict, the mixing plant will send special personnel to monitor the process or regularly designate personnel to conduct monitoring, which is an after-event treatment measure and has obvious disadvantages: First, it is impossible to steal materials in the early stage Second, a small amount of stolen materials is not obvious; third, there are many vehicles and transportation points, making monitoring and inspection difficult; fourth, it is time-consum...

Problems solved by technology

When the cement output of the mixing plant and the demand of the construction company frequently conflict, the mixing plant will send special personnel to monitor the process or regularly designate personnel to conduct monitoring, which is an after-event treatment measure and has obvious disadvantages: First, it is impossible to steal materials in the early stage Make up; second, a small amount of stolen materials is not obvious; third, there are many vehicles and transportation points, and it is difficult to monitor; fourth, it is time-consuming and laborious, and the effect is not obvious

like figure 1 , figure 1 It is the unloading control device of the mixer truck in the prior art. As shown in the figure, the angle of the electronically controlled oil pump actuator (solenoid valve) is controlled by the CAN bus controller 60, thereby changing the displacement of the oil pump, and matching with the rotation speed sensor 20 The feedback signal realizes the constant speed rotation of the tank during driving; the engine speed control is realized by controlling the angle of the engine throttle actuator; in addition, the remote control 50 is introduced to realize the remote operation of the mixer truck, and at the same time, the whole vehicle is matched with the operation display 30, It is used for the close control operation of the whole vehicle. Even if this measure has comprehensive functions, it has obvious disadvantages: First, the servo motor of the actuator in the tank rotation control must operate at a high frequency and with a certain load in the process of achieving a constant speed. , which puts forward very high requirements for the selection of the motor, which is difficult to meet in the current market; second, there is an obvious conflict between the electrical signal feedback of the system and the hysteresis of the mechanical structure, and it is difficult to obtain an ideal control effect; Third, the cost of the whole vehicle fluctuates greatly, and due to the high failure rate, electronically controlled mixer trucks have gradually withdrawn from the market, and the functions developed based on the electronically controlled system are not very practical

[0005] The patent number is "ZL200720033589.0", and the Chinese utility model patent named "GPS Vehicle Fuel Controller" discloses a vehicle fuel usage monitoring device loaded on a GPS / GPRS positioning device; the patent number is "ZL200620148828.2" , the Chinese utility model patent named "GPS tracking and positioning device for container trucks" failed to solve the problem of real-time monitoring of materials by material transport vehicles during transportation, and could not guarantee the safety of materials during transportation
