Description

Technical Field

[0001] The present invention relates to the field of concrete mixture transportation, and in particular to a vehicle-mounted concrete mixture remote monitoring and adjustment system and method. Background Art

[0002] Concrete is the most widely used building material today. It is the largest man-made product in the world by volume. In the past decade, in my country alone, the total annual output of commercial concrete has reached an astonishing 2 billion cubic meters - except for water, no material consumed by humans has reached such a huge amount. There is no doubt that the quality of concrete structure entities is not only directly related to the overall quality of construction projects, but also to the safety of people's lives and property. The primary factor affecting the quality of concrete structure entities is the quality of ready-mixed concrete. Among the many indicators for evaluating the quality of ready-mixed concrete, the construction performance of ready-mixed concrete is the most important. It can be said that ready-mixed concrete has good construction performance and is the primary factor in ensuring the quality of concrete structure entities.

[0003] During the transportation and construction of concrete mixtures, the construction performance of concrete mixtures will decrease over time due to the influence of various factors such as raw material quality, transportation time, on-site construction conditions, and environmental conditions, and admixtures need to be added for adjustment. However, there is currently a lack of equipment that can effectively monitor the concrete mixture during transportation and construction and remotely and conveniently add admixtures. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a vehicle-mounted concrete mixture remote monitoring and adjustment system.

Since the corresponding button remote control of the corresponding device is a well-known technology in the art, the specific principle of the remote control and APP controlling the start of devices such as electric control valves is not described in detail in the present application specification) The electric control box is also provided with a time relay electrically connected to the controller to improve the accuracy and performance of the remote control system of the entire electric control box. The remote control or mobile phone APP software is mainly wirelessly connected to the 4G switch controller through the 4G router in the electric control box. The camera is a vehicle-mounted camera, which is mainly controlled and connected with the 4G control switch through the camera host in the electric control box. The display is mainly wirelessly connected to the 4G control switch through the 4G router, which is used to receive and display the image information from the camera. The display can be a separate display or a mobile phone display. A fill light connected to the controller is also provided at the corresponding position of the camera on the mixer truck. When the light is dim or at night, the fill light can be turned on for fill light.

[0007] Preferably, the system further comprises a channel sensor installed in the mixer truck exit channel and used for sensing the mixer truck, and the channel sensor is wirelessly connected to the controller. The channel sensor mainly uses a license plate recognition sensor or an RFID sensor to sense the vehicle when it leaves the factory.

[0008] Preferably, the mixer truck is also equipped with an interval timer electrically connected to the controller. The interval timer is mainly used for timed reminders. During the transportation of the concrete mixture, the staff can be reminded to observe the concrete mixture at regular intervals.

[0009] Preferably, a GPS locator electrically connected to the controller is also installed in the electrical control box. The GPS locator mainly receives signals transmitted by a transmitter at the construction site of the project through a GPS antenna, and is used to sense the position of the mixer truck.

[0012] [A method for remote monitoring and adjusting a vehicle-mounted concrete mixture provided by the present invention]

[0013] A method for remote monitoring and adjustment of vehicle-mounted concrete mixture: the method comprises

[0014] Factory preparation steps: The vehicle loaded with concrete mixture passes through a dedicated channel with induction. When the vehicle is sensed, the remote monitoring device is activated;

[0015] Monitoring steps: The controller controls the camera to shoot the concrete mixture in the mixer truck and transmits the shot images to the display for the staff to view;

[0016] Adjustment steps: The staff checks the image information and determines whether it is necessary to add admixtures to the concrete mixture through image information analysis. When it is determined that admixtures need to be added, the controller remotely controls the electric control valve to open, and the admixture in the admixture box flows into the mixing drum of the mixer truck until the staff determines that it is qualified, and then stops adding admixtures;

[0017] Transportation steps: After the mixer truck leaves the factory, the remote monitoring device is turned on to monitor the concrete mixture in the mixer truck through video, and the interval timer is used to count the time. After a certain period of time, the controller controls the alarm on the display to remind the staff to check the monitoring video of the concrete mixture regularly. When the concrete mixture is unqualified, the control adjustment device is used to add admixtures, and regular observation is carried out according to the interval timer until the concrete is transported to the construction site;

[0018] Steps to arrive at the construction site: Pre-locate the construction site of each project, set up an electronic fence, and use GPS to locate the mixer truck when it arrives at the construction site. An alarm will sound on the display to remind the staff to check the monitoring video of the concrete mixture. When the construction performance of the concrete mixture is unqualified, the control and adjustment device will be used to add admixtures until the staff determines that it is qualified.

[0019] Unloading step: When the concrete mixture reaches the construction site with qualified construction performance, the driver clicks the unloading application button, and the mixer truck starts unloading. After unloading, the driver clicks the unloading end button, and the monitoring of the mixer truck for this trip ends;

[0020] Shooting and storage steps: When the concrete mixture is unloaded, the camera shoots a video of the concrete mixture during unloading, and stores the shot video and sends it to the cloud.

[0021] The interval timer has a timing period of 25-30 minutes, but the specific time can be set as needed. The interval timer is mainly used to regularly remind remote monitoring staff to monitor the concrete mixture and add admixtures during the transportation of the mixer truck.

[0022] By adopting the above technical solution, the beneficial effects of the present invention are:

[0023] 1. The camera can capture the state of the concrete mixture on the mixer truck and transmit the image to the display. The staff can observe the state of the concrete mixture through the image and observe whether its construction performance meets the requirements. When it is determined that adjustment is needed by adding admixtures, the staff remotely controls the electric control valve to open through the controller to add admixtures, thereby effectively monitoring the concrete mixture and adding admixtures.

[0024] 2. When the mixer truck is loaded and leaves the factory, the channel sensor is used to start the remote monitoring device to monitor the concrete mixture. When it is determined that admixtures need to be added to the concrete mixture, the staff can remotely control the adjustment device to add admixtures. At the same time, during the transportation and construction of the concrete mixture, regular monitoring and adjustment are also carried out, so that regular monitoring and adjustment can be achieved throughout the entire concrete mixture from leaving the factory, transportation, arriving at the construction site, and construction process.

[0031] Meanwhile, in the following description, many specific details are set forth for the purpose of explanation to provide a thorough understanding of the embodiments of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without the specific details or the specific manner described herein.

[0032] In the present disclosure, terms such as "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are relational words determined only for the convenience of describing the structural relationships of the various parts or elements of the present disclosure, and do not specifically refer to any part or element in the present disclosure and should not be understood as limitations on the present disclosure.

[0033] Example 1

[0034] Reference Figure 1The mixer truck filled with concrete mixture goes through the special channel in the factory. After passing through the special channel, it is sensed by the license plate recognition sensor. The sensing signal is transmitted to the staff's mobile phone through the 4G control switch through the 4G route to remind the staff. The staff operates the remote monitoring and adjustment device accordingly. The on-board camera is turned on to shoot the concrete mixture in the mixing drum, and the video is remotely transmitted to the staff's mobile phone through the 4G route. The staff observes the image of the concrete mixture and determines whether admixture needs to be added (the staff can generally judge whether it is necessary to observe the state of the concrete mixture). Add admixtures. Because workers often come into contact with concrete on construction sites, they can determine whether admixtures need to be added by observing the state of concrete). Touch the corresponding button and control the electric control valve to open through the 4G control switch to add admixtures until the concrete state is qualified. During the transportation of concrete, by setting an interval timer, a reminder signal is automatically transmitted to the mobile phone through the 4G route every 30 minutes to remind the workers to monitor. The workers operate the remote monitoring and adjustment device. When admixtures need to be added, the opening and closing of the electric control valve can be controlled to add admixtures to determine or adjust the workability of the concrete mixture. After the requirements are met, click the OK button and the warning is lifted. When the mixer truck arrives at the construction site, the GPS locator receives the signal from the construction site through the GPS antenna, and sends a reminder signal to the mobile phone through the 4G route. The remote monitoring personnel operate the remote monitoring and adjustment device again to confirm or adjust the working performance of the concrete mixture to meet the requirements and click the OK button. The warning is lifted. Before the mixer truck is ready to unload, the driver clicks the unloading application button (installed in the central control of the mixer truck) to issue an unloading application, which makes the pressure sensor sense and transmits the signal to the mobile phone through the 4G route to remind the remote monitoring personnel. The staff operates the remote monitoring and adjustment device After the whole device is adjusted to determine or adjust the working performance of the concrete mixture to meet the requirements, unloading is carried out. If the unloading time exceeds 30 minutes, the system will automatically issue an early warning under the action of the interval timer. The staff operates the remote monitoring and adjustment device to determine or adjust the working performance of the concrete mixture to meet the requirements and click the OK button to release the early warning. When unloading, the camera shoots a 15S video of the concrete mixture during unloading. The staff will store the video and send it to the cloud, and mark the project name, construction site, strength grade, date, time and other information. The entire operating system can also be connected to the production management system.

[0035] Example 2

[0036] Reference Figure 2Based on Example 1, this embodiment is further provided with a communication device, which includes a speaker arranged on the mixer truck and electrically connected to the controller, and a microphone wirelessly connected to the controller. The remote monitoring staff can communicate with the driver on the mixer truck through the microphone, which is convenient for communication with the driver. Mainly, during the process of transporting and unloading by the mixer truck, there may be problems with the camera shooting, and the shooting angle needs to be adjusted. This is convenient for the remote monitoring personnel to communicate with the driver in time and deal with the problems.

[0037] Example 3

[0038] Reference Figure 3 , Figure 4 In this embodiment, a reverse locking device is provided on the basis of embodiment 2. The reverse locking device is mainly an electric latch installed on the mixer truck. The electric latch is electrically connected to the remote 4G control switch; wherein, referring to Figure 5 The electric latch is installed at an appropriate position on the mixer truck, and the purpose of controlling the reversal of the mixer drum is achieved by limiting / releasing the reversal stroke of the linkage rod for controlling the forward and reverse operation of the mixer drum (the original structure on the mixer truck requires the operation linkage rod to move forward and backward to achieve the reversal or non-reversal of the mixer drum, and the specific operation linkage rod moves backward to reverse and unload the mixer drum); the specific electric latch includes an electric telescopic rod and a limit rod, and the electric telescopic rod can drive the limit rod to move, and the operation is limited and locked or unlocked through the telescopic movement of the limit rod. The limit rod is located at the rear side of the protrusion at the end of the operating linkage rod and abuts against the protrusion to achieve a limiting effect. Of course, the limiting structure can also be a limiting hole set on the operating linkage rod, so that the limit rod is ejected and stuck in the limiting hole, so that the operating linkage rod can also be limited. There are various limiting structures, which can be set according to actual conditions.

[0039] When the limit rod is extended, it abuts against the operating linkage rod, so that the operating linkage rod cannot move backward, and then reverse unloading cannot be performed (the structure and principle of the operating linkage rod are common knowledge to technicians in this field and are not described in detail in this embodiment. In this embodiment, the limit rod is extended and retracted to achieve the limit rod and the operating linkage rod abutting or separating, and then the operating linkage rod can be moved backward).

[0040] The electric telescopic rod is mainly electrically connected to the 4G control switch, and the remote monitoring personnel can operate the corresponding button to remotely control the power on / off of the electric telescopic rod through the 4G routing to lock / release the reverse function of the mixing drum. Power on: the electric telescopic rod drives the limit rod to extend, reverse lock, and the reverse lock indicator light in the mixer truck cab lights up. Power off: the electric telescopic rod drives the limit rod to extend and retract, unlock, and release the reverse lock. The reverse lock indicator light in the mixer truck cab goes out. The mixing drum can only be unloaded in the reverse state. The reverse locking device enables the remote monitoring staff to effectively control the unloading of the mixer truck; specifically: the staff operates the remote monitoring and adjustment device, determines or adjusts the working performance of the concrete mixture to meet the requirements, and then clicks the reverse lock function release button of the mixer truck. The driver can use the reverse function to unload normally.

[0041] It should be noted that many specific details are set forth in the above description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed above.
