[0033] Referring to the accompanying drawings and specific embodiments, the structure, composition, features and advantages of the safety alarm system of this utility model and the compression station including it will be described by way of example below. However, all descriptions should not be used to limit this utility model in any way.

Therefore, these further embodiments according to the present invention should also be considered within the scope of the description herein.

[0035] It should also be noted that the terms "inner", "outer", "top", "below", etc., indicate the orientation or positional relationship based on the orientation or positional relationship of the equipment in the safety alarm system and the equipment in the compression station shown in the accompanying drawings. They are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0037] In the description of this disclosure, "multiple" means at least two, such as two, three or more, unless otherwise expressly and specifically limited.

[0038] from Figure 1 As can be seen, the compression station of this utility model is provided with a restricted area 2, an operating area 3, and a compression area 4 from the outside to the inside. The restricted area 2 is the entrance to the compression station, and garbage trucks deliver their containers containing small pieces of garbage into the compression station through the restricted area 2.

[0039] Working area 3 is the parking area for garbage truck containers. The containers empty their garbage into compression area 4. Compression area 4 is equipped with a compressor 41 (e.g., ...). Figure 3 As shown, the compressor 41 is equipped with a hook 44, which can hold the truck body tightly and tilt the truck body towards the compressor 41, causing the garbage inside the truck body to be dumped under the compressor 41 for compression. After dumping, the garbage truck will transport the truck body out of the compression station.

[0040] To ensure safety, no personnel are allowed inside the compression station during the entire process of transporting the garbage container, dumping garbage, and transporting it out. Therefore, this utility model provides a safety alarm system to detect the position of the garbage container inside the compression station, the operation status of the compressor 41, and whether there are personnel inside the compression station. It alerts compression station staff, surrounding personnel, and garbage truck drivers to the current operating status of the compression station and issues alarms to personnel already inside and entering the compression station during operations, requiring them to evacuate the station.

[0041] from Figure 2 As can be seen, the compression station safety alarm system of this utility model includes a detection module 11, a controller 1, and an alarm module 12. Both the detection module 11 and the alarm module 12 are connected to the controller 1. The detection module 11 is used to detect the condition of the carriages and personnel inside the compression station and send signals to the controller 1.

[0042] The controller 1 receives signals from the detection module 11 and controls the alarm module 12 to issue an alarm based on the received signals, so as to remind personnel to pay attention to safety, evacuate the compression station, and not enter the compression station when working in the compression station.

[0043] Controller 1 can be as follows Figure 2 The PLC controller in the embodiment can also be, for example, but not limited to, a microcomputer controller, as long as it can integrate the detection module 11 and the alarm module 12 and control the operation of the detection module 11 and the alarm module 12.

[0044] from Figure 2 As can be seen, the detection module 11 includes an access control sensor 21, a cabinet sensor 31, and a human body sensor 32.

[0045] Access control sensor 21 is installed at the access control zone 2 of the compression station to detect whether personnel or vehicles are passing through the access control zone 2. Access control sensor 21 can be an infrared grating sensor, combined with... Figure 1 and Figure 3 As can be seen, the two infrared grating sensors are respectively set on both sides of the door restricted area 2, corresponding to each other. Multiple beams can be formed between the two infrared grating sensors. When the beam is blocked, the infrared grating sensor receives a signal that changes and sends a signal to the controller 1, indicating that the vehicle or personnel have entered the door restricted area 2.

[0046] Optionally, the access control sensor 21 can be installed at a position one meter above the ground in the access control zone 2 to ensure that the passage of personnel or vehicles can be detected.

[0047] Combination Figure 1 and Figure 3 It can also be seen that the box sensor 31 is located at the top of the work area 3 and is used to detect whether a vehicle box passes through the work area 3 and the position of the box in the work area 3.

[0048] The enclosure sensor 31 is a diffuse reflection photoelectric sensor, such as... Figure 3As shown, two horizontal bars are suspended at the top longitudinal ends of the work area 3, near the door restricted area 2 and near the compression area 4, respectively. Diffuse reflection photoelectric sensors are installed on the two horizontal bars. The diffuse reflection photoelectric sensor near the door restricted area 2 can detect the truck bed entering the work area 3. When the diffuse reflection photoelectric sensor near the compression area 4 detects the truck bed, it means that the truck bed has been completely parked in the work area 3, and the next step of unloading can be carried out.

[0049] It is understood that different types of garbage trucks have different container heights. To adapt to different container heights, the diffuse reflection photoelectric sensor can be further equipped with a beam adjustment device. The beam adjustment device is used to adjust the beam length of the diffuse reflection sensor, that is, the distance between the beam and the object, so that the beam can detect the object, thereby adapting to the container height of different types of garbage trucks and ensuring that the diffuse reflection photoelectric sensor can accurately detect the container.

[0050] from Figure 1 and Figure 3 It can also be seen that the human body sensor 32 is installed on both sides of the working area 3, that is, on both sides of the truck when the truck is parked in the working area 3. The human body sensor 32 is used to detect whether there are personnel on both sides of the truck when the compression station is operating.

[0051] from Figure 2 It can also be seen that the alarm module 12 includes a first alarm light 33, a second alarm light 34, and an audible and visual alarm 35. For example... Figure 3 As shown, the first alarm light 33, the second alarm light 34, and the audible and visual alarm 35 are located in a conspicuous position near the top of the compression station to alert the compression station personnel, surrounding personnel, and drivers to the current operation status of the compression station.

[0052] Specifically, the first alarm light 33 is used to indicate the operating status of the compression station and the personnel status within the compression station. When the controller 1 receives signals from the access control sensor 21 and / or the human body sensor 32, it sends instructions to the first alarm light 33 and the audible and visual alarm 35 based on the received signals, causing the first alarm light 33 and the audible and visual alarm 35 to sound an alarm to indicate that the compression station is in operation and that no personnel are allowed inside the compression station.

[0053] Furthermore, the first alarm light 33 can be a red-green alarm light. When the access control sensor 21 does not detect an object, such as a person or a cabinet, and the human body sensor 32 does not detect a person, the controller 1 controls the first alarm light 33 to turn green, and the audible and visual alarm 35 does not work. When the access control sensor 21 detects an object, such as a person or a cabinet, or when the human body sensor 32 detects a person, it sends a signal to the controller 1. The controller 1 controls the first alarm light 33 to turn red, and simultaneously controls the audible and visual alarm 35 to turn on and play a warning voice or ringtone.

[0054] In other embodiments, the first alarm light 33 may also be a single-color alarm light, which illuminates when an alarm is triggered and remains off at other times. The first alarm light 33 may also be other multi-colored alarm lights to indicate various conditions within the compression station.

[0055] In the embodiment shown in the figure, the compressor 41 can move between several connected compression stations, and the hook 44 of the compressor 41 moves with the compressor 41. A hook sensor 42 is provided at the hook 44, which is used to detect the movement of the hook 44. The hook sensor 42 is connected to the first alarm light 33 through a relay 43, that is, the hook sensor 42 controls the first alarm light 33 in each compression station individually.

[0056] Specifically, when the hook 44 clamps the container, the hook sensor 42 sends a signal to the relay 43, causing the relay 43 to control the first alarm light 33 to illuminate red, indicating that the compressor 41 is working and warning personnel not to enter the compression station, while also prompting personnel inside the compression station to leave. When the hook 44 releases the container, the hook sensor 42 sends a signal to the relay 43, causing the relay 43 to control the first alarm light 33 to illuminate green, indicating that the garbage dumping operation is complete.

[0057] The second alarm light 34 is used to indicate the status of the garbage truck's container within the compression station. Specifically, when the controller 1 receives a signal from the container sensor 31, it sends a command to the second alarm light 34 based on the received signal, causing the second alarm light 34 to sound an alarm.

[0058] The second alarm light 34 can also be a red-green alarm light. When the container sensor 31 does not detect the container, the controller 1 controls the second alarm light 34 to turn green. When the container sensor 31 detects the container, the controller 1 controls the second alarm light 34 to turn red, indicating that the container has entered the working area 3 within the compression station. When both container sensors 31 detect the container simultaneously, it indicates that the container has been parked in place within the working area 3 of the compression station.

[0059] In other embodiments, the second alarm light 34 may also be a single-color alarm light, illuminating when an alarm is triggered and remaining off at other times. The second alarm light 34 may also be other multi-color alarm lights to indicate various conditions of the carriages within the compression station.

[0060] Furthermore, such as Figure 1 and Figure 3 As shown, the first alarm light 33 and the second alarm light 34 are set separately, on both sides of the compression station, to prevent confusion.

[0061] The safety alarm system of this utility model for the compression station serves as an alarm during the operation of the compression station, reminding personnel that the compression station is in operation, to pay attention to safety, and to evacuate from the compression station and not to enter the compression station.

[0062] Specifically, the garbage truck delivers a container filled with loose, small pieces of garbage into the compression station. The container first enters the restricted area 2, triggering the access control sensor 21. The access control sensor 21 detects the object and sends a signal to the controller 1. The controller 1 controls the first alarm light 33 to turn red, and simultaneously controls the audible and visual alarm 35 to turn on and emit an alarm sound or voice.

[0063] Then, the truck bed enters work area 3. The access sensor 21 does not detect any object, so the controller 1 activates the first alarm light 33 to turn green and stops the audible and visual alarm 35. Simultaneously, the truck bed entering work area 3 triggers the body sensor 31, which sends a signal to the controller 1. The controller 1 then activates the second alarm light 34 to turn red. When both body sensors 31 detect an object, it indicates that the truck bed is parked in the correct position in work area 3, ready to be tipped over.

[0064] It should be noted that when the container sensor 31 uses a diffuse reflection photoelectric sensor, the illumination length of the diffuse reflection photoelectric sensor's beam needs to be adjusted by the beam adjustment device to adapt to the current height of the garbage truck's container.

[0065] Next, the hook 44 of the compressor 41 at the compression zone 4 clamps the truck bed and tilts the truck bed to dump the garbage inside the truck bed under the compressor 41. The hook sensor 42 detects the clamping action of the hook 44 and sends a signal to the relay 43. The relay 43 controls the first alarm light 33 to turn red to indicate that the compressor 41 is working.

[0066] After the garbage is dumped, the hook 44 straightens the truck bed and detaches from the truck bed. The hook sensor 42 detects the detachment of the hook 44 and sends a signal to the relay 43. The relay 43 controls the first alarm light 33 to turn green to indicate that the garbage dumping is complete.

[0067] Finally, the garbage truck transports the container out of the work area 3. When neither of the two container sensors 31 detects an object, it sends a signal to the controller 1. The controller 1 then controls the second alarm light 34 to turn green to indicate that the container has been transported out of the work area 3.

[0068] The container passes through access control zone 2 again, triggering access control sensor 21. Sensor 21 then sends a signal to controller 1, which in turn activates the first alarm light 33 to turn red and simultaneously activates the audible and visual alarm 35, emitting an alarm sound or voice. This continues until the container is completely removed from the compression station. At this point, access control sensor 21 sends a signal to controller 1, which then activates the first alarm light 33 to turn green. Thus, the compression station operation is complete.

[0069] During the entire operation, once the human body sensor 32 or the access control sensor 21 detects a person, it sends a signal to the controller 1. The controller 1 controls the first alarm light 33 to turn red, and at the same time controls the sound and light alarm 35 to turn on and emit an alarm sound or alarm voice.

[0070] Therefore, it can be concluded that if either the first alarm light 33 or the second alarm light 34 is red, it indicates that the compression station is in operation, warning personnel not to enter the compression station or to evacuate from the compression station to ensure personnel safety.

[0071] The compression station of this utility model uses a safety alarm system to monitor the condition of the carriage inside the compression station and the presence of personnel inside the compression station at all times during operation, and issues corresponding alarms to ensure personnel safety.

[0072] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
