Detailed Description

In order that the objects and advantages of the present application will become more apparent, the present application will be described in detail with reference to the following examples. It is understood that the following text is intended only to describe one or several particular embodiments of the application and does not strictly limit the scope of the claims which are specifically claimed herein, and that the examples and features of the examples in this application may be combined with one another without conflict.

The problems faced by the embodiments of the present application are: the traditional optical cable splice box for the tower has some disadvantages in the use process, such as: most equipment requires a person to make periodic visits, and staff will only detect a significant failure of the splice closure. If communication failure occurs, due to the fact that the basic conditions of the position where the failed joint box is located and the site cannot be judged, workers cannot check along the line, a large amount of manpower is consumed, real-time monitoring and real-time early warning of the internal condition of the joint box are difficult to carry out, and risk factors cannot be effectively restrained when the failure does not occur. Because the optical cable splice box for the tower is deployed at the high places of outdoor electric towers and electric poles for a long time for use, the environment is very severe. The main risk factor and the drawback that face of current optical cable splice box for tower are:

(1) the optical cable joint box for the tower is subjected to dust-proof and waterproof failures, so that the internal humidity rises;

(2) the optical cable connector box for the tower inclines, and the connector box sealed by the hoop is very easy to incline due to the larger weight of the bell cover part of the connector box, so that the connector box is further likely to overturn, and the hidden trouble of water accumulation inside the connector box and the damage of optical fibers are caused.

(3) The temperature inside the optical cable splice box for the tower is too high. In the case of direct sunlight during the day, high temperature and high humidity can accelerate the aging of internal critical components.

(4) The position information of the optical cable splice closure for the tower greatly depends on a database, particularly the position information and the accumulated running time information, real-time updating is difficult to achieve, and once the database is not updated in time, a large amount of time and energy of workers are consumed.

In order to solve the above problem, chinese patent application CN110501794A discloses an optical cable splice closure with humidity detection function and air pressure balancing device, which is characterized in that an optical fiber grating humidity sensor can be used to detect the internal humidity, and the pressure is released by a pressure self-adjusting mechanism when the internal air pressure is too high.

However, due to the adoption of the scheme that the data receiving and transmitting and positioning module is externally arranged, the connector needs to be installed on the joint box shell, and potential safety hazards exist. In addition, the data adopts the SIM card communication mode, the power consumption is still larger and the cost is higher compared with the latest NB-IOT and LoRa technologies.

This patent application adopts the mode of external device but place the terminal box in the temperature and humidity sensor in the same and carries out state monitoring, and the splice box outside is all arranged in to all key subassemblies, to the sensor that inside monitoring needs, needs the trompil to implant. The technical scheme that this patent application provided lacks the collection to information such as atmospheric pressure, light intensity, in addition, the device has the part to be located inside reliable protection casing, but data antenna, battery are directly external to lack effectual thermal-insulated measure, there is the reliability risk. The solar cell panel is directly externally arranged and outside the joint box, the protection is lacked, and the long-time dust accumulation greatly weakens the photovoltaic power generation efficiency of the solar cell panel. The communication mode is based on the SIM7600CE, and the power consumption is larger.

The main controller 260 is electrically connected to the sensor module 290, the LPWAN communication module 270, and the positioning module 280, respectively. The LPWAN communication module 270 is electrically connected to the LPWAN communication antenna 220 via the main control electronics board 250. The LPWAN communication antenna 220 is in communication connection with the cloud server; the positioning module 280 is electrically connected to the positioning module antenna 230 through the main control electronics board; the positioning module antenna 230 is in communication connection with a satellite positioning system, wherein the satellite positioning system includes one or more of a GPS satellite positioning system, a beidou satellite positioning system, and a GLONASS satellite positioning system.

The preset threshold is written not only into the main controller but also into each sensor, and the reason why the sensor is written into is that the main controller has two working states:

one is, master controller 260 works under the mode of waking up regularly in inside, and each sensor data is gathered to master controller 260 under this mode to compare the data of gathering with the preset threshold value of writing in advance in the master controller 260, and then judge whether there is the alarm incident, if there is the alarm incident then send early warning information or alarm information to the high in the clouds via LPWAN communication antenna 220 by master controller 260. This mode is short in duration;

secondly, the main controller 260 operates in an external wake-up mode, i.e. a sleep state, and needs to be woken up by sending a sleep interrupt signal from the outside and then can operate normally. In this mode, the master controller 260 is first in a low power consumption sleep state, and the master controller 260 does not have the capability of acquiring the environment parameters. In order to continuously obtain the early warning capability of the environmental parameters, the parameters are written into the corresponding sensors. When the environmental parameter exceeds the preset threshold range written in the sensor in advance, the sensor sends a wake-up signal to wake up the main controller 260. After the main controller 260 is awakened, the data of each sensor still can be collected again, and the collected data is compared with a preset threshold value written in the main controller 260 in advance, so that whether an alarm event exists or not is judged; the main controller 260 is in the working state of the external wake-up mode most of the time, so that a large amount of energy consumption can be saved, and the adaptability of the device in long-time operation in a field environment is improved.

Of course, those skilled in the art can understand that the preset threshold written in each sensor and the threshold written in the master controller 260 may not be completely the same, and usually, the threshold set by the preset threshold written in the sensor may be slightly lower than the threshold set by the preset threshold in the master controller 260, so that once an abnormality occurs, the master controller 260 may be awakened in advance, and more reaction and processing time is reserved for the master controller 260, so as to feed back the early warning or alarm information to the cloud server in time, and thus, the fault discovery and troubleshooting operations are more timely and faster.
