Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, specifically to a communication fault monitoring terminal that supports BeiDou short message service. Background Technology

[0002] In addition to providing global positioning, navigation and timing services, the BeiDou system can also conduct short message communication. Short message communication is similar to the SMS function of a mobile phone. It refers to the ability of BeiDou ground terminals, BeiDou satellites and BeiDou ground monitoring stations to directly transmit information in two directions through satellite signals. It is a functional feature of the BeiDou system.

[0003] Traditional fault monitoring terminals, when in use, have a fault monitoring module installed inside the communication equipment to collect the signal strength value, data transmission rate, and link connectivity status of the communication link, and then transmit the collected data to the control module for fault diagnosis. However, when installing communication equipment, it is fixed to the working bracket through the mounting holes on the surface of the connecting ears on both sides of the shell. Since the connecting ears on both sides are mostly fixed to the shell, it is impossible to adjust the connecting ears. This makes it difficult to accurately match the distance between the mounting holes of the connecting ears and the fixing points of the working bracket. Either the distance deviation is too large to fix directly, or it is necessary to re-drill holes, which increases the difficulty of installation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a communication fault monitoring terminal that supports BeiDou short messages. It solves the problem that since the connecting ears on both sides are mostly fixed to the outer shell, it is impossible to adjust the connecting ears on both sides, which makes it difficult to accurately match the distance between the mounting holes of the connecting ears and the fixing points of the working bracket. Either the distance deviation is too large to fix directly, or it is necessary to re-drill holes, which increases the installation difficulty.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a communication fault monitoring terminal supporting BeiDou short message service, comprising a housing, a monitoring component disposed inside the housing, a recessed post disposed at the bottom of the housing, a horizontal post inserted into the recessed post, an installation hole formed on the end surface of the horizontal post, a cover fixedly connected to the side wall of the recessed post, a stud rotatably connected to the outer wall of the cover via a sealed bearing, a connecting post threadedly connected to the outer wall of the stud, a horizontal bar fixedly connected to the inner wall of the cover, the connecting post penetrating the horizontal bar and movably connected to the horizontal bar, an insertion hole formed on the outer wall of the horizontal post, an insertion rod fixedly connected to the side wall of the connecting post, the insertion rod extending into the recessed post, and the outer wall of the insertion rod being inserted into the inner wall of the insertion hole.

[0006] Preferably, the inner wall of the concave column is provided with a sliding groove, the side wall of the horizontal column is fixedly connected with a slider, and the outer wall of the slider is slidably engaged with the inner wall of the sliding groove.

[0007] Preferably, a countersunk bolt is threaded between the recessed post and the outer shell, and two countersunk bolts are provided on one of the recessed posts.

[0008] Preferably, the bottom of the outer shell is fixedly connected to a connecting ear, the inner wall of the connecting ear is rotatably connected to a rotating shaft via a sealed bearing, the outer wall of the rotating shaft is fixedly connected to a vertical block, and the side wall of the vertical block is fixedly connected to the outer wall of a concave column on the side away from the cover.

[0009] Preferably, an empty box is fixed to the side wall of the outer casing near the rotating shaft, the end of the rotating shaft extends into the interior of the empty box, a screw is threaded to the upper part of the inner wall of the empty box, a pawl is rotatably connected to the bottom of the screw via a bearing, the outer wall of the pawl fits against the inner wall of the empty box, and a toothed groove is formed on the outer wall of the end of the rotating shaft, the outer wall of the pawl is engaged with the inner wall of the toothed groove.

[0010] Preferably, the monitoring component includes a battery, which is fixed to one side of the inner wall of the housing by screws. Inside the housing, a control module and a fault monitoring module are fixed to each other by screws. On the top of the housing, an antenna and an alarm are fixed to each other by screws.

[0011] Beneficial effects This utility model provides a communication fault monitoring terminal supporting BeiDou short message service. It has the following advantages: This communication fault monitoring terminal supporting BeiDou short message service, through the cooperation of the housing, studs, connecting columns, crossbars, and inserts, allows for adjustment of the distance between the mounting holes on the surfaces of the two crossbars. This solves the problem that since the connecting ears on both sides are mostly fixed to the outer shell, they cannot be adjusted, leading to difficulty in accurately matching the distance between the mounting holes of the connecting ears and the fixing points of the working bracket. This results in either excessive spacing deviation preventing direct fixing or requiring re-drilling, increasing installation difficulty.

[0012] By connecting the lugs, shafts, uprights, empty boxes, screws, pawls, and toothed grooves, the angle of the mounting holes can be adjusted. This solves the problem that when communication equipment needs to be installed on the inclined support of a communication tower in a mountainous area, the support has an inclination, and the fixed mounting holes can only be forcibly fitted, which can easily cause the main body of the equipment to tilt and shift. This makes it impossible for the mounting holes of traditional communication equipment to be adapted to supports with different inclination angles. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Since the connecting ears on both sides are mostly fixed to the outer shell, they cannot be adjusted. This makes it difficult to accurately match the distance between the mounting holes of the connecting ears and the fixing points of the working bracket. Either the distance deviation is too large to fix directly, or it is necessary to re-drill holes, which increases the difficulty of installation.

[0017] In view of this, the present invention provides a communication fault monitoring terminal that supports BeiDou short message service. Through the cooperation between the cover, studs, connecting columns, crossbars and plugs, the distance between the mounting holes on the surfaces of the two crossbars can be adjusted. This solves the problem that since the connecting ears on both sides are mostly fixed to the outer shell, it is impossible to adjust the connecting ears on both sides. This makes it difficult to accurately match the distance between the mounting holes of the connecting ears and the fixing points of the working bracket. Either the distance deviation is too large to be directly fixed, or it is necessary to re-drill holes, which increases the installation difficulty.

[0018] Those skilled in the art will connect the electrical components and their compatible power supplies in this case using wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control.

[0019] Example 1, by Figure 1-5 It is understood that a communication fault monitoring terminal supporting Beidou short message in this case includes a shell 1, a monitoring component 2 is provided inside the shell 1, a recessed post 3 is provided at the bottom of the shell 1, a horizontal post 5 is inserted into the recessed post 3, an installation hole 6 is opened on the end surface of the horizontal post 5, a cover 7 is fixedly connected to the side wall of the recessed post 3, a stud 8 is rotatably connected to the outer wall of the cover 7 through a sealed bearing, a connecting post 9 is threadedly connected to the outer wall of the stud 8, a horizontal bar 10 is fixedly connected to the inner wall of the cover 7, the connecting post 9 passes through the horizontal bar 10 and is movably connected to the horizontal bar 10, an insertion hole 12 is opened on the outer wall of the horizontal post 5, an insertion rod 11 is fixedly connected to the side wall of the connecting post 9, the insertion rod 11 extends into the interior of the recessed post 3, and the outer wall of the insertion rod 11 is inserted into the inner wall of the insertion hole 12; In the specific implementation process, it is worth noting that the end of the stud 8 has a hexagonal recess, and there are several insertion holes 12 arranged at equal intervals. The stud 8 is an M6 stainless steel bolt, and the sealing bearing model is 608ZZ. When installing the communication equipment, the worker first inserts a wrench into the recess and rotates the wrench to rotate the stud 8. The stud 8 drives the connecting post 9 to move. The connecting post 9 moves in the crossbar 10, which limits the movement of the connecting post 9. The connecting post 9 then drives the insertion rod 11 to move, and the insertion rod 11 moves away from the insertion hole. Hole 12, release the fixation of the horizontal column 5, and then the worker moves the horizontal column 5. The horizontal column 5 moves in the concave column 3, which in turn drives the mounting hole 6 to move. The mounting hole 6 is moved into the threaded hole on the bracket. After that, the worker turns the wrench in the opposite direction, so that the stud 8 rotates in the opposite direction, so that the insertion rod 11 is inserted into the corresponding insertion hole 12 and the horizontal column 5 is fixed. After the adjustment is completed, the worker installs the entire equipment onto the bracket through the mounting hole 6, so as to adjust the distance between the mounting holes 6 on the surface of the horizontal columns 5 on both sides. Furthermore, a groove 13 is provided on the inner wall of the concave column 3, and a slider 14 is fixedly connected to the side wall of the horizontal column 5. The outer wall of the slider 14 is slidably engaged with the inner wall of the groove 13. In the specific implementation process, it is worth noting that when the horizontal column 5 moves, the horizontal column 5 drives the slider 14 to move. The slider 14 slides in the groove 13 to limit the horizontal column 5 and prevent the horizontal column 5 from moving out of the concave column 3. Furthermore, countersunk bolts 4 are threadedly connected between the recessed post 3 and the outer shell 1, with two countersunk bolts 4 provided on one recessed post 3; In the specific implementation process, it is worth noting that the bottom of the outer shell 1 is provided with several equally spaced threaded holes, which are matched with countersunk bolts 4. The operator rotates the countersunk bolts 4 to rotate them out of the threaded holes, releasing the concave post 3 from the fixation. The operator moves the concave post 3 and fixes it in the designated position. After completion, the operator rotates the countersunk bolts 4 in the opposite direction to rotate them back into the corresponding threaded holes, fixing the concave post 3 in place, thereby adjusting the distance between the concave posts 3. Furthermore, a connecting ear 15 is fixedly connected to the bottom of the outer shell 1, and a rotating shaft 16 is rotatably connected to the inner wall of the connecting ear 15 through a sealed bearing. A vertical block 17 is fixedly connected to the outer wall of the rotating shaft 16, and the outer wall of the concave post 3 is fixedly connected to the side away from the cover 7. In the specific implementation process, it is worth noting that when the communication equipment needs to be installed on the bracket with different slopes, the staff rotates the concave column 3, which drives the upright block 17 to rotate, the upright block 17 drives the rotating shaft 16 to rotate, the rotating shaft 16 rotates in the connecting ear 15, the concave column 3 drives the horizontal column 5 to rotate, and then drives the mounting hole 6 to rotate, so that the mounting hole 6 is rotated to the angle of the bracket slope. After that, the staff stops rotating the concave column 3, so as to adjust the angle of the mounting hole 6. Furthermore, an empty box 18 is fixedly connected to the side wall of the outer casing 1 near the rotating shaft 16. The end of the rotating shaft 16 extends into the interior of the empty box 18. A screw 19 is threadedly connected to the upper part of the inner wall of the empty box 18. A pawl 20 is rotatably connected to the bottom of the screw 19 through a bearing. The outer wall of the pawl 20 fits against the inner wall of the empty box 18. A toothed groove 21 is opened on the outer wall of the end of the rotating shaft 16. The outer wall of the pawl 20 is engaged with the inner wall of the toothed groove 21. In the specific implementation process, it is worth noting that the end of the screw 19 is provided with a hexagonal concave hole. When rotating the concave post 3, the operator inserts a wrench into the concave hole at the end of the screw 19 and rotates the wrench to make the screw 19 rotate. The screw 19 rotates in the empty box 18, and the screw 19 drives the pawl 20 to move. The pawl 20 moves on the inner wall of the empty box 18, limiting the pawl 20 and causing it to leave the tooth groove 21, thus releasing the fixation of the rotating shaft 16. After completion, the operator rotates the concave post 3. After rotation, the screw 19 rotates in the opposite direction, causing the pawl 20 to re-insert into the corresponding tooth groove 21, thus fixing the rotating shaft 16 again, thereby fixing the rotated rotating shaft 16.

[0020] Example 2, by Figure 1 and 2 It is known that the monitoring component 2 includes a battery 201, which is fixed to one side of the inner wall of the housing 1 by screws. The control module 202 and the fault monitoring module 203 are fixed to the inside of the housing 1 by screws respectively. The antenna 204 and the alarm 205 are fixed to the top of the housing 1 by screws respectively. In the specific implementation process, it is worth noting that the battery 201 uses an NCR18650BD lithium battery pack, and the control module 202 uses an STM32F103RCT6 microcontroller as the core control unit. It has powerful data processing and logic control capabilities, low power consumption and strong stability. It is responsible for coordinating the work of various modules, analyzing fault data and executing instructions. The fault monitoring module 203 integrates an AD8310 signal strength detection chip, a MAX30102 data transmission rate detection chip and a link continuity detection circuit. It can collect communication link parameters (signal strength, transmission rate, link continuity status) from multiple dimensions and accurately identify the fault type. The antenna 204 uses a BD-300 Beidou-3 short message antenna, which supports bidirectional communication and a maximum single message transmission volume of 100 bytes. It can realize fault information reporting and remote command reception, breaking through the limitations of ground network coverage. The alarm 205 uses a YMB-12 sound and light alarm, powered by 12V. It realizes local fault indication through red LED flashing and buzzer sound, which makes it easy for on-site personnel to quickly identify abnormalities. The battery 201 provides power to the entire communication equipment. Fault Acquisition: The fault monitoring module 203 collects the signal strength (AD8310), data transmission rate (MAX30102), and link connectivity status of the communication link in real time, and transmits the data to the control module 202. Fault Judgment: The control module 202 analyzes the collected parameters. When the signal strength is below -85dBm, the data rate is below 10kbps, or the link interruption lasts for more than 5 seconds, it is determined to be a fault. Alarm and Reporting: The control module 202 triggers the alarm 205 to perform a local audible and visual alarm. At the same time, it sends a short message through the Beidou antenna 204 to report information such as the fault type, terminal location (provided by the Beidou positioning module BD-200), and fault time to the monitoring center. Command Execution: The monitoring center can send remote commands (such as fault reset and parameter adjustment) through Beidou short messages. After receiving the command, the antenna 204 transmits it to the control module 202, which executes the corresponding operation and feeds back the result. Battery 201 serves as the core power source, powered by RVV2×0.75mm. 2 The copper core sheathed wires are connected to the power input terminal (VCC pin, input voltage 12V) of the control module 202, the power interface (DC12V terminal) of the fault monitoring module 203, and the power supply terminal (12V terminal) of the alarm 205. An AMS1117-5V voltage regulator chip (integrated in the control module 202) is connected in series between the battery 201 and each module to stabilize the 12V voltage to 5V and provide an adaptation voltage for the control module 202 and the fault monitoring module 203, so as to avoid damage to components due to voltage fluctuations. All wiring is double-fixed by soldering and pluggable terminals. The terminals are sealed with heat shrink tubing to prevent poor contact caused by outdoor humid environment. The control module 202 acts as the signal hub, connecting to the communication interface of the fault monitoring module 203 via an AWG28 I2C communication cable (SDA / SCL dual wires). This enables the real-time transmission of data such as signal strength and transmission rate collected by the fault monitoring module 203 to the control module 202. The IO output pins (PA0 / PB1) of the control module 202 are connected via an RVV2×0.5mm cable. 2 The wires are connected to the signal trigger terminal of the alarm 205. When the control module 202 determines a fault, it triggers the alarm 205 with an audible and visual alarm through high and low level signals. The antenna 204 (BD-300 Beidou antenna) is directly connected to the Beidou communication interface (SMA female connector) of the control module 202 through an RG174 type SMA coaxial cable (with shielding layer). The shielding layer of the coaxial cable is connected to the grounding terminal of the outer shell 1 to reduce outdoor electromagnetic interference and ensure stable transmission of short message signals. All data harnesses are fixed through the ABS cable trays preset on the inner wall of the outer shell 1. The trays are lined with cushioning sponge to prevent equipment vibration from causing wear or loosening of the harnesses.
