Description

Technical Field

[0001] The present invention relates to the field of power communication, and specifically to an optical cable splice closure fault monitoring device based on Beidou positioning short message. Background Art

[0002] Xinjiang has a vast territory. The characteristics of "three mountains sandwiching two basins" also make the terrain and climate in Xinjiang complex, and the regional environment is harsh. Most optical cable splice closures are located in areas without signals (no mobile network), and the status information of the optical cable splice closures cannot be monitored in real time. There are also frequent occurrences of high-frequency wind disasters, and there are often faults such as the optical cable splice closure being blown off by the wind or optical fiber transmission problems caused by changes in the attitude of the splice closure. This poses a threat to the safe and stable operation of the optical cable line. The disadvantages of traditional optical cable splice closure monitoring technologies are as follows:

[0003] (1) There is no information communication function in the traditional optical cable splice closure, and the information of the faulty optical cable splice closure cannot be sent to the operation and maintenance personnel in time.

[0004] (2) Due to the absence of a positioning device in the traditional optical cable splice closure, the staff cannot obtain real-time accurate position information of the splice closure, resulting in the inability to timely discover the position of the faulty splice closure.

[0005] (3) There is no tilt angle monitoring device in the traditional optical cable splice closure, and it is impossible to analyze and judge whether the optical cable splice closure has faults such as being blown off by the wind or attitude changes based on the change of the swing angle of the optical cable splice closure.

[0006] In the existing optical cable splice closure monitoring technologies, we do not have a device dedicated to the precise positioning of optical cable splice closures, real-time monitoring of position and attitude, and reporting of fault warnings to the management platform. Therefore, it is necessary to adopt relevant monitoring and warning technologies to monitor the optical cable splice closures to ensure the safe, reliable and stable operation of the communication network. So we invented this product. Compared with traditional monitoring means, in the present invention, tilt sensors are installed at key positions of the optical cable splice closures on power poles and towers. The attitude information (changes in coordinates along the X and Y axes) of the optical cable splice closures is collected by the sensors, and the tilt angle data is sent to the terminal software, thereby judging whether the optical cable splice closures have faults such as being blown off by the wind or attitude changes, realizing intelligent monitoring. And the longitude and latitude of the location where the optical cable splice closure is located are determined through the Beidou communication positioning module and sent to the terminal in real time.

[0031] The present invention has been tested many times, simulating its different working states outdoors, by monitoring the normal working of the optical cable joint box, the different degrees of shaking in strong wind weather, and the falling of the optical cable joint box in different position postures. The present invention outputs its corresponding data, fully reflecting the position and pose information of the joint box, and can accurately and real - time understand the working state of the optical cable joint box. At the same time, more severe external environments such as strong wind, heavy rain, and scorching sun are simulated, and the present invention can work normally.

[0032] As Figures 1 to 4 shown, it shows the specific implementation manner of the present invention.

[0033] An optical cable joint box fault monitoring device based on Beidou positioning short message, characterized by comprising: Optical cable joint box body, solar panel support frame, tilt sensor, power supply module, communication and positioning module. Among them, the power supply module includes solar panel 31, solar controller 32, storage battery 33. The communication and positioning module includes Beidou short message development board 41, Beidou antenna 42.

[0034] In an embodiment of the present invention, 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 storage 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.

[0035] In the embodiment of the present invention, the solar panel support frame is composed of 21 top mounting frames, 22 vertical brackets, 23 stainless steel clamps, 24 fixing screws, 25 gaskets, 26 locking bolts, and 27 limit grooves. Among them, the top mounting frame and the vertical bracket are connected by gaskets and fixing screws. Clamp limit grooves are welded on both sides of the vertical bracket. The clamp is placed in the limit groove to fix the position of the clamp on the vertical bracket. The clamp is equipped with a locking bolt to lock the clamp. The solar cell support is made of the metal material iron. The solar panel is placed on the solar panel support frame at an inclination of 45°. The solar controller, Beidou development board, and battery are placed inside the optical cable connector box.

[0036] In the embodiment of the present invention, the Beidou development board selects the Beidou short message development board N2S. By adopting 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 attitude information of the inclination sensor to the Beidou module through the MODBUS protocol. After parsing with its NMEA0183 protocol, it is transmitted to the terminal, so as to achieve the purpose of monitoring.

[0037] The present invention 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 connector box can be detected in real time according to the change of the angle when the optical cable connector box swings. Its measurement range is plus or minus 90 degrees. The inclination sensor is placed at the key position of the optical cable connection box on the power pole tower. The sensor collects the attitude information of the optical cable connector box (the change of the coordinates along the X and Y axes), and its inclination data is sent to the terminal software, so as to judge whether the optical cable connector box has faults such as being blown off by the wind and attitude change, realizing intelligent monitoring.

[0038] Design of the battery of the solar power generation and energy storage system.

[0039] Capacity design of the battery in the embodiment of the present invention The power supply voltage of the inclination sensor and the 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 energy storage device to ensure that the two devices work 24 hours a day and the continuous rainy days are 3 days. The capacity calculation formula of the battery 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 continuous rainy days, and η is the reserve coefficient). In order to prevent the battery from being overcharged, the battery is generally charged to about 90%, so take n = 1 / (90%) = 1.1. Battery capacity C = 0.16A * 24h * 3 * 1.1 = 12.7Ah 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.

[0040] Calculation of the Design Peak Power of Solar Cells

[0041] The peak power calculation formula for solar panels is Wp = (I * H * η * U) / h (where Wp is the peak power, I is the working current, H is the working time, h is the average light illumination time, η is the reserve coefficient, and U is the solar cell voltage). The principle of the calculation formula is derived based on the conservation of electricity (energy), that is, Wp * h = I * H * U * η, which is transformed Taking Urumqi area as an example, the average daily light illumination time is 4.2 hours, and the minimum reserve amount is relaxed by 20% of the demand. Since the storage battery is 12V, the voltage of the solar panel needs to exceed 20% - 30% of the working voltage of the storage battery to ensure normal charging of the storage battery. Therefore, the battery panel needs to be matched with 18V to ensure normal charging. Thus, the voltage U of the solar panel = 18V

[0042] The daily power generation of the solar cell meets the working requirements of the electrical equipment for 24 hours Wp = 18V * 0.16A * 24h * 1.2 / 4.2 = 19.74W. In addition, the line loss and controller loss of the solar module are different. In actual application, it may be 5% - 25%. Therefore, taking a loss of 10%, the actual peak power of the solar panel is 19.74W * 1.1 = 21.7W

[0043] Therefore, the solar panel is selected with a working voltage of 18V and a rated power of 20W

[0044] Selection of Solar Controller

[0045] Since 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 Therefore, the solar controller is selected with a working voltage of 12V and a rated current of 10A

[0046] In the specific implementation, the tilt sensor is a high-precision tilt angle measurement device. By installing it on the optical cable joint box, the tilt angle of the joint box can be monitored in real time. Once tilt or abnormal conditions are detected, the system will immediately send an alarm signal for the staff to handle in a timely manner

[0047] To ensure the long-term operation of the device, we introduce solar panels and solar controllers. The solar panel collects and converts solar energy into electrical power supply, providing a stable power source for the device. The solar cell controller is responsible for charging and power supply management to ensure the normal operation of the power supply device

[0048] In addition, the device is equipped with a Beidou module, which is used to obtain the longitude and latitude coordinates of the location where the device is located 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 joint box. Whether it is a regular inspection or a quick location of the fault point, it can be more efficient and accurate.
