Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of detection and alarm, and in particular relates to a garbage bin position detection and alarm device. Background Art
[0002] With the acceleration of urbanization, domestic waste disposal has become a crucial component of urban management. To improve waste collection and transportation efficiency, detachable garbage trucks are widely used in urban waste removal. Among them, 31-ton detachable garbage trucks, a common large-scale waste removal tool, are widely used by sanitation departments in many cities. These vehicles are typically equipped with automated loading and unloading systems, enabling quick and safe loading and unloading of waste containers.
[0003] On existing 31-ton detachable garbage trucks, the control system monitors whether the garbage bin is correctly placed by a pair of signal sensors installed on the left and right sides of the front end of the upper body. When the garbage bin is accurately placed in place, the spring above the signal sensor will be pressed down due to pressure, thereby triggering the sensor to send a signal to the display device in the cab, showing the "upper bin" closed state (green), indicating that the front has completed the bin operation. At this point, the driver can proceed to the next step, which is to lock the front locking pin to secure the bin. Conversely, when the garbage bin is removed, the spring returns to its original position and no longer triggers the signal sensor. The cab displays the "upper bin" open state (red), indicating that the bin has left the vehicle.
[0004] Although the above design principles seem simple and practical, they expose some potential safety risks and technical defects in actual application:
[0005] First, due to wear and tear or aging caused by long-term use, the spring on the signal sensor may lose its original elastic properties and fail to return to its initial position properly even when the bin is not being placed. This means that even if the correct placement of the bin is not actually completed, the signal sensor continues to detect an error signal and feeds back a false "normal bin placement" status to the cab. This false alarm not only misleads the driver's operational judgment, but can also lead to serious consequences. For example, if the garbage bin is not properly locked at the front locking pin, and the driver believes that everything is normal and starts the unloading procedure, it is very likely to cause the bin to slip, resulting in economic losses or even casualties.
[0006] Secondly, the logic design of the existing control system has obvious deficiencies. Specifically, the currently used single-chip microcontroller fails to implement the linkage and interlocking function between the front and rear case placement signals. In theory, only when all four case placement points are accurately detected can the entire case be confirmed to be fully in place; similarly, as long as any point does not trigger a signal, it should be considered that the case has not been correctly installed. However, in reality, regardless of whether the case placement process is complete, once a partial case placement signal appears at a certain stage, the system defaults to the final status display mode without further checking whether other key points have also met the expected requirements. Worse, for those intermediate states between fully placed and not placed, the system lacks the necessary audio and visual alarm mechanisms to alert the operator to abnormal conditions. Therefore, such design loopholes significantly reduce the safety of the entire loading and unloading process.
[0007] In summary, the 31-ton dump trucks currently on the market have significant technical shortcomings in their control systems. These issues not only impact the reliability and service life of the equipment itself, but more importantly, pose a direct threat to jobsite safety. Therefore, an improved solution is urgently needed that can ensure high-precision bin detection while strengthening information interaction and synergy between various components, thereby fundamentally resolving the various existing safety hazards. This will help improve the overall efficiency of garbage collection and transportation while protecting the lives and property of those involved. Utility Model Content
[0008] The technical problem solved by the utility model is to provide a garbage bin position detection alarm device to solve the problem in the prior art that the 31-ton detachable garbage truck has insufficient garbage bin position detection and reminder capabilities during bin detection.
[0009] The basic solution provided by the utility model is a garbage bin position detection and alarm device, comprising a detection device, an alarm device, and a control device. The detection device comprises at least four bin placement detection modules, and the at least four bin placement detection modules are installed on a garbage truck; the control device comprises a controller, and the bin placement detection modules and the alarm device are both electrically connected to the controller;
[0010] The box placement detection module is used to detect the box placement status of the garbage box on the garbage truck, and send a box placement signal to the controller; the controller is used to control the operating status of the alarm device according to the box placement signal of the box placement detection module.
[0011] Furthermore, the detection device includes a first box in place detection module, a second box in place detection module, a third box in place detection module and a fourth box in place detection module. The first box in place detection module and the second box in place detection module are located on both sides of the front end of the garbage box placement area on the garbage truck, and the third box in place detection module and the fourth box in place detection module are located on both sides of the rear end of the garbage box placement area on the garbage truck.
[0012] Furthermore, it also includes an in-place detection plate, and the detection device also includes an in-place detection module;
[0013] The in-place detection plate is located at the front end of the garbage truck, and the in-place detection module is installed on the side of the in-place detection plate opposite to the garbage bin. The in-place detection module is electrically connected to the controller. The in-place detection module is used to send an in-place detection signal after the garbage bin contacts the in-place detection plate, and transmit it to the controller. The controller is also used to control the operating status of the alarm device according to the in-place detection signal.
[0014] Furthermore, the control device also includes a delay module, which is electrically connected to the controller. Each time the controller receives the first arrival detection signal, it controls the delay module to perform delay processing, and after the delay processing is completed, it controls the operating status of the alarm device according to the received box arrival signal.
[0015] Furthermore, the alarm device includes an indicator light, which is electrically connected to the controller;
[0016] The controller is a single-chip microcomputer, which includes an AND gate circuit. The box placement detection module is connected to the input end of the AND gate circuit. The AND gate circuit outputs a high-level signal when it receives the box placement signals from all the box placement detection modules, and outputs a low-level signal when it does not receive the box placement signals from all the box placement detection modules. The single-chip microcomputer controls the indicator light to start when it receives the high-level signal, and controls the indicator light to turn off according to the low-level signal.
[0017] Furthermore, the alarm device also includes an audible and visual alarm, which is electrically connected to the controller. The single-chip microcomputer is also used to control the sound and light alarm to start when a low-level signal is received after the delay processing is completed, and the single-chip microcomputer is also used to control the sound and light alarm to turn off when a high-level signal is received after the delay processing is completed.
[0018] The principle and advantage of the present invention are: in this application, for the 31-ton detachable garbage truck, it is necessary to ensure that the garbage bin on the garbage truck is placed in place during the loading and unloading process. For the accuracy detection in this regard, in this solution, first, at least four bin placement detection modules are set in the area where the garbage bin is placed on the garbage truck, for example, two are set on both sides of the front end of the placement area, and two are set on both sides of the rear end, which are used to detect whether the garbage bin is covered on the bin placement detection module when it is placed on the garbage truck, so that only after receiving the signals from all the bin placement detection modules, a bin placement reminder will be generated. Otherwise, as long as any bin placement detection module does not transmit a signal, an alarm reminder will be issued.
[0019] Therefore, the present application solution adds the detection of the intermediate state of the placement position of the garbage bin on the garbage truck, so that the user can receive timely reminders of the garbage bin status, and improve the reminder capability of the garbage bin in place detection.

[0024] The following is further described in detail through specific implementation methods:
[0025] The symbols in the drawings of the specification include: garbage truck 1, garbage truck arrival detection module 2, arrival detection board 3, arrival detection module 4.
[0026] On existing 31-ton dump trucks, the control system monitors the proper placement of the garbage bin using a pair of signal sensors mounted on the left and right sides of the front end of the upper body. During this process, the current single-chip microcontroller fails to implement interlocking between the front and rear bin placement signals. Theoretically, the bin is fully seated only when all four bin placement points are accurately detected; similarly, if any point fails to trigger a signal, the bin is considered improperly installed. However, in reality, regardless of the complete placement process, if a partial placement signal appears at any stage, the system defaults to the final status display mode without further checking to ensure that other key points have met the expected requirements. Worse still, the system lacks the necessary audible and visual alarm mechanisms to alert the operator to any abnormalities between fully and partially seated bins. This design flaw significantly compromises the safety of the entire loading and unloading process.
[0027] In this regard, the technical solutions and embodiments of this application are basically as shown in the attached Figure 1 and Figure 2 As shown: A garbage bin position detection and alarm device includes a detection device, an alarm device, a control device and an in-place detection plate 3, wherein the detection device in this application includes at least four bin in-place detection modules 2 and in-place detection modules 4. Specifically, taking the four bin in-place detection modules 2 as an example, they are a first bin in-place detection module 2, a second bin in-place detection module 2, a third bin in-place detection module 2 and a fourth bin in-place detection module 2. The first bin in-place detection module 2 and the second bin in-place detection module 2 are located on both sides of the front end of the garbage bin placement area on the garbage truck 1, and the third bin in-place detection module 2 and the fourth bin in-place detection module 2 are located on both sides of the rear end of the garbage bin placement area on the garbage truck 1; as shown Figure 2 As shown, the first box placement detection module 2 is point A of the upper box (left detection point), the second box placement detection module 2 is point B of the upper box (right detection point); the third box placement detection module 2 is point C of the lower box (right detection point), and the fourth box placement detection module 2 is point D of the lower box (left detection point).
[0028] The in-place detection plate 3 is located at the front end of the garbage bin placement area on the garbage truck 1, and the in-place detection module 4 is installed on the side of the in-place detection plate 3 opposite to the garbage bin. In this way, when the garbage bin is loaded, its front end touches the in-place detection plate 3, and an in-place detection signal is generated on the in-place detection plate 3. After subsequent signal transmission, the operator can know that the front of the garbage bin is in place. Combined with the functions of multiple in-place detection modules 2, the operator's operation results are clearer when loading the garbage bin.
[0029] The control device includes a controller and a delay module, wherein the delay module, the box arrival detection module 2, the arrival detection module 4 and the alarm device are all electrically connected to the controller. After the controller receives the box arrival signals from all the box arrival detection modules 2, the controller controls the operating state of the alarm device. At the same time, each time the controller receives the first arrival detection signal, the controller controls the delay module to perform delay processing, and controls the operating state of the alarm device according to the received box arrival signal after the delay processing is completed; similarly, the arrival detection module 4 sends an arrival detection signal after the garbage bin body contacts the arrival detection plate 3, and the controller receives the arrival detection signal to control the operating state of the alarm device.
[0030] In order to better realize the technical solution of the present application, the alarm device is configured to include an indicator light and an audible and visual alarm, wherein the indicator light in this embodiment includes an in-place indicator light and a delay indicator light, and the in-place indicator light, the delay indicator light and the audible and visual alarm are electrically connected to the controller, and the controller in this application adopts a single-chip microcomputer, and the single-chip microcomputer realizes the signal transmission of each detection device by setting an AND gate circuit. Specifically, each box-in-place detection module 2 is connected to the input end of the AND gate circuit, and the AND gate circuit generates a high-level signal after receiving the box-in-place signals of all the box-in-place detection modules 2. If all the box-in-place detection modules are not received, the signal transmission of each detection device is realized. 2's box placement signal outputs a low-level signal, that is, at least four box placement detection modules 2 arranged in the garbage box placement area on the garbage truck 1, only when all of them generate box placement signals, the AND gate circuit will generate a high-level signal. If there is one or more box placement detection modules 2 without a box placement signal, the AND gate circuit will output a low-level signal. Therefore, in this solution, all box placement detection modules 2 generate box placement signals as the final state, and all box placement detection modules 2 do not generate box placement signals as the initial state. In the intermediate state from the initial state to the final state, this application performs real-time detection.
[0031] like Figure 3 As shown, after the AND gate circuit outputs a high-level signal, the single-chip microcomputer controls the in-place indicator light to start, and the operator can thereby activate the lock pin of the garbage truck 1 to lock the garbage box; Figure 4 As shown, when the single chip microcomputer does not receive a level signal or receives a low level signal, the control indicator light is turned off;
[0032] The delayed processing signal of the delay module represents that the placement status of the garbage bin in the placement area on the garbage truck 1 is being loaded. At this time, after the delay processing is completed, if the microcontroller still receives a low-level signal, it means that the garbage bin is not loaded in place, and the sound and light alarm is activated to alarm, reminding the operator to check the status of the garbage bin in time to avoid the situation of incomplete loading; and when the delay processing is completed, the microcontroller receives a high-level signal, which means that the garbage bin is loaded in place, and the sound and light alarm is turned off. If the sound and light alarm is not activated, no processing is required.
[0033] Therefore, in the technical solution of this application, in order to address the problem of insufficient accuracy in detecting the loading position of the garbage bin in the existing 31-ton detachable garbage truck, its loading position detection function is improved. By adding an AND gate circuit to the control circuit of the single-chip microcomputer and supplementing it with different alarm devices, comprehensive and multi-faceted detection reminders are achieved.
[0034] In addition, in this embodiment, the box landing detection module 2 adopts a box landing signal sensor, the arrival detection module 4 adopts an arrival detection sensor, and the delay module is a timer in the single chip microcomputer.
