Description

Technical Field

[0001] The utility model relates to the technical field of granary dust monitoring, in particular to a granary dust monitoring and early warning device. Background Art

[0002] Grain storage is a crucial component of agricultural production, directly impacting grain quality and safety. However, due to the characteristics of grain and the storage environment, large amounts of dust and dirt often accumulate inside silos. This dust not only affects air quality and the health of workers, but also poses a potential threat to electrical equipment installed within the silos, such as distribution boxes and air conditioning units.

[0003] To ensure the proper functioning of electrical equipment within granaries and prevent equipment damage or safety incidents caused by dust, regular monitoring of dust concentration within the silo is necessary. Traditional monitoring methods rely on manual inspections, which are inefficient and difficult to achieve continuous monitoring. This prevents managers from taking timely action, leading to delayed equipment maintenance and significantly increasing safety risks. Utility Model Content

[0004] The technical problem solved by the utility model is to provide a granary dust monitoring and early warning device, which can realize real-time remote monitoring of the dust concentration in the granary, and remotely alarm when the concentration exceeds the standard, so as to promptly remind management personnel to take measures to improve the safety of electrical equipment in the granary.

[0005] The basic solution provided by the utility model is: a granary dust monitoring and early warning device, including a dust monitoring mechanism and a remote early warning mechanism;

[0006] The dust monitoring mechanism includes a first controller, a dust concentration sensor, and a first communication module, wherein the first controller is electrically connected to the dust concentration sensor and the first communication module respectively, and the dust concentration sensor is arranged on an electrical device in the granary;

[0007] The remote warning mechanism includes a second controller, a second alarm, and a second communication module, wherein the second controller is electrically connected to the second alarm and the second communication module respectively;

[0008] The dust monitoring mechanism and the remote warning mechanism are communicatively connected via a first communication module and a second communication module.

[0009] The technical principle and effect of this solution: In this solution, the first controller in the dust monitoring mechanism is used to collect the dust concentration value around the electrical equipment in the granary through the dust concentration sensor. The first controller is also used to judge whether the dust concentration around the electrical equipment in the granary exceeds the standard by comparing the collected dust concentration value with the preset concentration threshold. The first controller is used to send an alarm signal to the remote early warning mechanism through the first communication module when it is judged that the dust concentration around the electrical equipment in the granary exceeds the standard. The second controller in the remote early warning mechanism is used to receive the alarm signal sent by the first communication module through the second communication module, and start the second alarm for remote alarm.

[0010] This solution achieves remote monitoring and early warning of dust around electrical equipment in the granary through cooperation between the dust monitoring agency and the remote early warning agency, greatly improving the safety of the electrical equipment in the granary. That is, it can realize real-time remote monitoring of the dust concentration in the granary and remotely alarm when the concentration exceeds the standard, so as to promptly remind management personnel to take measures to improve the safety of the electrical equipment in the granary.

[0011] Furthermore, the dust monitoring mechanism also includes a delay module and a first alarm electrically connected to the first controller.

[0012] Beneficial effect: In this solution, the first controller is used to activate the first alarm at the first time when it is determined that the dust concentration around the electrical equipment in the granary exceeds the standard. At this time, the staff around the granary can know that the dust concentration around the corresponding electrical equipment in the granary exceeds the standard through the alarm sound of the first alarm. At the same time, the delay module is activated to delay for a period of time. If the dust concentration returns to normal during the delay, the delay is stopped. Otherwise, the delay is maintained until the end. The delay module sends an end signal. After receiving the end signal, the first controller sends an alarm signal to the remote early warning agency through the first communication module, thereby realizing remote early warning. The setting of the delay module prevents false alarms and avoids harassment to remote users, because when carrying out activities in the granary, there will occasionally be a short moment when the concentration rises.

[0013] Furthermore, the dust monitoring mechanism further includes a shell, the first controller, the first communication module and the delay module are arranged in the shell, and the shell is provided with an installation slot for installing the dust concentration sensor and the first alarm.

[0014] Beneficial effect: The shell protects the various components in the dust monitoring mechanism, greatly improving the reliability of the dust monitoring mechanism.

[0015] Furthermore, the shell and the electrical equipment in the granary are detachably connected via a connecting portion.

[0016] Beneficial effects: In this solution, the shell and the electrical equipment in the granary are detachably connected, thereby realizing a detachable connection between the dust monitoring mechanism and the electrical equipment. When the corresponding electrical equipment or dust monitoring mechanism fails or requires regular maintenance, the detachable connection design makes the equipment better, simpler and faster, without the need for complicated disassembly and assembly work. At the same time, through quick disassembly and installation, the downtime caused by maintenance or replacement of equipment can be significantly reduced, thereby improving the availability and work efficiency of the equipment.

[0017] Furthermore, the connecting portion includes a buckle provided on the electrical device and a slot provided on the housing, and the housing and the electrical device are detachably connected by matching the buckle with the slot.

[0018] Beneficial effect: The matching design of the buckle and the slot can provide a stable connection, ensuring that the shell will not loosen or fall off due to vibration or external force during normal use of the electrical equipment.

[0019] Furthermore, the connecting part includes a first connecting part arranged on the electrical equipment and a second connecting part arranged on the shell, the first connecting part includes a first connecting base and a first magnet fixed on the first connecting base, the second connecting part includes a second connecting base and a second magnet fixed on the second connecting base, and the polarities of the first magnet and the second magnet are configured to attract each other.

[0020] Beneficial effects: By adopting the mutual attraction design of the first magnet and the second magnet, the connection between the electrical equipment and the housing not only becomes simpler and faster, but also improves the stability and reliability of the connection, reduces maintenance costs, and enhances the safety, adaptability and reliability of the system.

[0021] The mutual attraction of the magnets helps the device align automatically, and even if it is not perfectly aligned during installation, the magnets will guide the device to the correct position.

[0022] Furthermore, threaded holes for bolts to extend into are provided at corresponding positions of the first connecting seat and the second connecting seat.

[0023] Beneficial effect: In this solution, the threaded hole is provided so that after the first magnet and the second magnet are adsorbed, the bolt is extended into the second connecting seat and the first connecting seat to achieve auxiliary fixation of the two adsorbed magnets.

[0024] Furthermore, the first alarm and the second alarm both include a buzzer and a warning light.

[0025] Beneficial effect: Dual prompts are given through sound and light tubes to ensure that users can receive alarm reminders.

[0026] Furthermore, the first communication module and the second communication module are both wireless communication modules.

[0027] Furthermore, the wireless communication module includes one or more of a WIFI module, a Bluetooth module, a ZigBee module, and a Lora module. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is further described in detail through specific implementation methods:

[0031] The symbols in the drawings of the specification include: housing 1 , first connecting base 2 , second connecting base 3 , first magnet 4 , and threaded hole 5 .

[0032] The embodiment is basically as shown in the attached Figure 1 and Figure 2 Shown: A granary dust monitoring and early warning device, including a dust monitoring mechanism and a remote early warning mechanism;

[0033] The dust monitoring mechanism includes a shell 1, a first controller, a dust concentration sensor, a first communication module, a delay module and a first alarm; a circuit board is provided in the shell 1, and the first controller, the first communication module and the delay module are all arranged on the circuit board and electrically connected through the circuit board. The shell 1 is provided with an installation slot for installing the first alarm and the dust concentration sensor.

[0034] The first controller is electrically connected to the dust concentration sensor, the delay module, the first alarm, and the first communication module respectively. The dust concentration sensor is arranged on the electrical equipment in the granary. The housing 1 is detachably connected to the electrical equipment in the granary through a connecting portion. In this embodiment, the connecting portion includes a first connecting portion arranged on the electrical equipment and a second connecting portion arranged on the housing 1. The first connecting portion includes a first connecting seat 2 and a first magnet 4 fixed on the first connecting seat 2. The second connecting portion includes a second connecting seat 3 and a second magnet fixed on the second connecting seat 3. The polarities of the first magnet 4 and the second magnet are configured to attract each other. Specifically, the first connecting seat 2 and the second connecting seat 3 are fixed to the electrical equipment and the housing 1 respectively by bolts and nuts. Afterwards, when the second magnet approaches the first magnet 4, since the polarities of the two magnets are configured to attract each other, the first magnet 4 and the second magnet will be attracted, thereby realizing detachable fixation between the connecting portion and the electrical equipment. In order to make the adsorption of the first magnet 4 and the second magnet more reliable, threaded holes 5 for bolts to be inserted are opened at corresponding positions of the first connecting seat 2 and the second connecting seat 3. The threaded hole 5 is provided so that after the first magnet 4 and the second magnet are adsorbed, the bolts are inserted into the second connecting seat 3 and the first connecting seat 2 to achieve auxiliary fixation of the two adsorbed magnets.

[0035] The remote warning mechanism includes a second controller, a second alarm, and a second communication module, wherein the second controller is electrically connected to the second alarm and the second communication module respectively;

[0036] The dust monitoring mechanism and the remote warning mechanism communicate with each other via a first communication module and a second communication module. Both the first and second communication modules are wireless communication modules. These wireless communication modules include one or more of a Wi-Fi module, a Bluetooth module, a ZigBee module, and a LoRa module. In this embodiment, both the first and second communication modules utilize Wi-Fi modules.

[0037] In this embodiment, the first connecting seat 2 is first fixed to the electrical equipment in the granary to be monitored by bolts and nuts, and then the second magnet on the corresponding dust monitoring mechanism is brought close to the first magnet 4 fixed on the first connecting seat 2. At this time, the first magnet 4 and the second magnet will attract each other and fix the dust monitoring mechanism on the electrical equipment. At the same time, after the bolts are penetrated into the threaded holes 5 on the first connecting seat 2 and the second connecting seat 3, further auxiliary fixation of the magnetic attraction between the first magnet 4 and the second magnet is achieved, after the dust monitoring mechanism is fixed in the granary.

[0038] The first controller in the dust monitoring mechanism is used to collect the dust concentration value around the electrical equipment in the granary through the dust concentration sensor. The first controller is also used to judge whether the dust concentration around the electrical equipment in the granary exceeds the standard by comparing the collected dust concentration value with the preset concentration threshold. The first controller is used to start the first alarm as soon as it is judged that the dust concentration around the electrical equipment in the granary exceeds the standard. At this time, the staff around the granary can know that the dust concentration around the corresponding electrical equipment in the granary exceeds the standard through the alarm sound of the first alarm. At the same time, the delay module is started to delay for a period of time. If the dust concentration returns to normal during the delay, the delay is stopped, otherwise the delay is maintained until the end, and the delay module sends an end signal. After receiving the end signal, the first controller sends an alarm signal to the remote early warning mechanism through the first communication module. The second controller in the remote early warning mechanism is used to receive the alarm signal sent by the first communication module through the second communication module, and start the second alarm for remote alarm.

[0039] The first and second controllers can be single-chip microcomputers or programmable logic controllers (PLCs). In this embodiment, an STM32 series single-chip microcomputer, specifically an STM32H7 high-performance series single-chip microcomputer, is used. The dust concentration sensor is the GCG1000. Both the first and second alarms include a warning light and a buzzer. In this embodiment, the warning light is a red LED. The delay module can be implemented using a timer built into the single-chip microcomputer or a 555 chip and its external circuitry. In this embodiment, the internal timer of the single-chip microcomputer is used, and the delay duration is 5 seconds.

[0041] Compared with the first embodiment, the difference of this embodiment is that the connecting portion includes a buckle provided on the electrical device and a slot provided on the shell 1, and the shell 1 and the electrical device are detachably connected by matching the buckle and the slot.

[0042] In this embodiment, the matching design can provide a stable connection, ensuring that the housing 1 will not become loose or fall off due to vibration or external force during normal use of the electrical device.
