Technical Field
[0001] The utility model relates to the field of electric power communication, in particular to an optical cable junction box fault monitoring device based on Beidou positioning short messages. Background Art
[0002] Xinjiang is a vast region with three mountains and two basins, which makes the terrain and climate in Xinjiang complex and the regional environment harsh. Most of the optical cable junction boxes are located in areas without signals (no mobile network), and the status information of the optical cable junction boxes cannot be monitored in real time. There are also frequent wind disasters, and the optical cable junction boxes often fall off due to wind, or the optical fiber transmission problems caused by the change of the junction box posture often occur. This poses a threat to the safe and stable operation of the optical cable line. The shortcomings of traditional optical cable junction box monitoring technology are as follows:
[0003] (1) The traditional optical cable splice box has no information communication function and cannot send the fault optical cable splice box information to the staff in time;
[0004] (2) Since traditional optical cable splice boxes do not have positioning devices, workers cannot obtain real-time accurate location information of the optical cable splice boxes, resulting in the inability to promptly discover the location of the faulty optical cable splice boxes;
[0005] (3) Traditional optical cable junction boxes do not have a tilt monitoring device, and cannot analyze and determine whether the optical cable junction box has fallen due to wind or has changed its posture based on the change in the swing angle of the optical cable junction box.
[0006] In the existing optical cable junction box monitoring technology, we do not have a device specifically used for the precise positioning of the optical cable junction box, real-time monitoring of the position and posture, and reporting fault warnings to the management platform. Therefore, it is necessary to use relevant monitoring and early warning technologies to monitor the optical cable junction box to ensure the safe, reliable and stable operation of the communication network. Compared with traditional monitoring methods, the utility model installs a tilt sensor at a key position of the optical cable junction box on the power tower. The sensor collects the attitude information of the optical cable junction box along the X and Y axis coordinates, and uses the Beidou short message development board to send these data to the host computer, so as to determine whether the optical cable junction box has fallen due to wind, posture changes, and other faults, thereby realizing intelligent monitoring. The longitude and latitude of the location of the optical cable junction box are determined by the Beidou communication positioning module and sent to the host computer in real time.

[0034] The utility model has been tested many times, simulating different working states outdoors, and monitoring the normal operation of the optical cable junction box, the shaking of different degrees in windy weather, and the falling of the optical cable junction box in different positions and postures. The utility model outputs the corresponding data, fully reflects the position and posture information of the junction box, and can accurately understand the working state of the optical cable junction box in real time. At the same time, the utility model can work normally in the severe external environment such as strong wind, heavy rain, and scorching sun.
[0035] like Figures 1 to 4 As shown, it shows a specific implementation of the utility model.
[0036] An optical cable junction box fault monitoring device based on Beidou positioning short message, characterized in that it includes:
[0037] The optical cable junction box body, the solar panel support frame, the tilt sensor, the power supply module, and the communication positioning module. The power supply module includes a solar panel 31, a solar controller 32, and a battery 33. The communication positioning module includes a Beidou short message development board 41 and a Beidou antenna 42.
[0038] In an embodiment of the utility model, a tilt sensor 5 and a Beidou antenna 42 are placed above the optical cable junction box 1; the output end of the solar panel 31 is connected to the input end of the solar controller 32; the output end of the battery 33 is connected to the battery end of the solar controller 32; the Beidou development board 41 and the tilt sensor 5 are connected to the output end of the solar controller 32.
[0039] In the embodiment of the utility model, the solar panel support frame includes 21 a top mounting frame, 22 a vertical support, 23 a stainless steel clamp, 24 a fixing screw, 25 a gasket, 26 a locking bolt, and 27 a limiting groove. The top mounting frame is connected to the vertical support through a gasket and a fixing screw, and clamp limiting grooves are welded on both sides of the vertical support. The clamp is placed in the limiting groove to fix the position of the clamp on the vertical support. The clamp is equipped with a locking bolt to lock the clamp. The solar cell support frame is made of metal material iron, and the solar panel is placed on the solar panel support frame at an angle of 45°. The solar controller, Beidou development board, and battery are placed inside the optical cable junction box.
[0040] In the embodiment of the utility model, the Beidou development board uses the Beidou short message development board N2S. By using the Beidou short message development board N2S, it will automatically report the longitude and latitude located by the positioning module to the satellite every 1 minute, and transmit the tilt sensor attitude information to the Beidou module through the MODBUS protocol, and transmit it to the terminal after parsing with the NMEA0183 protocol, so as to achieve the purpose of monitoring.
[0041] The utility model further adds the DYL626S-M inclination sensor to the monitoring device. By adopting the DYL626S-M inclination sensor, the swing amplitude of the optical cable junction box can be detected in real time according to the change of the angle when the optical cable junction box swings. The measurement range is plus or minus 90 degrees. The inclination sensor is placed at the key position of the optical cable junction box on the power pole tower. The sensor collects the posture information of the optical cable junction box (changes along the X and Y axis coordinates) and sends its inclination data to the terminal software, so as to determine whether the optical cable junction box has faults such as falling due to wind and posture changes, thereby realizing intelligent monitoring.
[0042] Design of battery for solar power generation and storage system
[0043] (1) Capacity design of the battery in the embodiment of the utility model
[0044] The power supply voltage of the tilt sensor and Beidou short message development board is 12V, the total power is about 2W, and the working current is 160mA. Design a solar power generation and storage device to ensure that the two devices work 24 hours a day and continuous rainy days for 3 days.
[0045] The battery capacity calculation formula is C = I*H*T*η (C is the battery capacity, I is the working current, H is the working time, T is the number of consecutive rainy days, and η is the reserved coefficient). In order to prevent the battery from being overcharged, the battery is generally charged to about 90%, so n=1 / (90%)=1.1.
[0046] Battery capacity C = 0.16A*24h*3*1.1 = 12.7Ah
[0047] Since the working voltage of the two devices is 12v, the battery is selected with a rated voltage of 12V and a rated capacity of 12AH.
[0048] (2) Calculation of design peak power of solar cells
[0049] The peak power calculation formula of solar panels is Wp = (I*H*η*U) / h (Wp is peak power, I is working current, H is working time, h is average illumination time, η is reserved coefficient, U is solar cell voltage). The principle of the calculation formula is derived from the conservation of electricity (energy), that is, Wp*h =I*H*U*η.
[0050] Taking Urumqi as an example, the average daily sunshine time is 4.2 hours, and the minimum reserve for demand is 20%. Since the battery is 12V, the voltage of the solar panel must exceed the battery working voltage by 20%-30% to ensure normal charging of the battery, so the solar panel must match 18V to ensure normal charging. Therefore, the voltage of the solar panel U = 18V.
[0051] The daily power generated by solar cells can meet the 24-hour working needs of electrical equipment
[0052] Wp = 18V*0.16A*24h * 1.2 / 4.2= 19.74W. In addition, the line loss of the solar panel and the loss of the controller are different, which may be 5%-25% in actual application. So if the loss is 10%, the actual peak power of the solar panel is 19.74W*1.1 = 21.7W.
[0053] Therefore, the solar panel is selected with an operating voltage of 18V and a rated power of 20W.
[0054] (3) 10. Selection of solar controller
[0055] Because it is necessary to ensure that when the solar cell charges the lithium battery, the voltage of the cell is 1.5 times the voltage of the solar controller.
[0056] Therefore, the solar controller is selected with an operating voltage of 12V and a rated current of 10A.
[0057] In practice, the inclination sensor is a high-precision inclination angle measuring device. By installing it on the optical cable junction box, the inclination angle of the junction box can be monitored in real time. Once a tilt or abnormal situation is detected, the system will immediately send an alarm signal so that the staff can deal with it in time.
[0058] To ensure that the device can work for a long time, we introduced solar panels and solar controllers. Solar panels provide a stable source of power for the device by collecting and converting solar energy into electricity. The solar cell controller is responsible for charging and power supply management to ensure the normal operation of the power supply device.
[0059] In addition, the device is equipped with a Beidou module to obtain the latitude and longitude coordinates of the device's location and transmit them to the data analysis system for further processing. With the high-precision positioning function provided by the Beidou system, the staff can accurately understand the location information of the optical cable junction box. Whether it is routine inspection or rapid positioning of fault points, it can be more efficient and accurate.
