Problems solved by technology

[0004] However, at present, the communication technology of the online monitoring system generally adopts GSM, GPRS and other public network wireless communication for real-time data transmission, but a considerable part of the transmission lines in China are located in areas with complex environments, remote locations, no public network coverage or unstable networks. Unable to use the public network to complete the online monitoring function

Embodiment 1

[0040] see figure 1 , an intelligent tower status monitoring terminal based on Beidou and 4G dual-mode communication, including a housing, a 4G antenna and a Beidou antenna arranged on the surface of the housing, a sensor, a processor, a 4G communication module, and a Beidou communication module installed inside the housing , Power module. The power supply module is electrically connected with the sensor, the processor, the 4G communication module and the Beidou communication module respectively.

[0041] The sensor is electrically connected with the processor. A monitoring cycle is set in the processor, and the processor starts the sensor regularly according to the monitoring cycle; after the sensor is started, it continuously collects multiple inclination angle data of the tower (collecting the inclination angle of the tower along the line and in the lateral direction) and sends it to the processor.

[0042] A data transmission period and a second threshold for judging whe...

Embodiment 2

[0048] Further, the processor adjusts the data transmission cycle according to the tilt angle value, and the specific steps are:

[0049]A first threshold for adjusting the data transmission period is preset. If none of the multiple inclination angle data collected continuously within one monitoring period exceeds the first threshold, the data transmission period is extended (for example, extended from 1 hour to 2 hours). If the plurality of inclination angle data collected continuously within one monitoring period all exceed the first threshold, the data transmission period is shortened. Taking a tower below 50m as an example, the first threshold is set to 0.02. The inclination angles in both directions along the line and in the lateral direction are both 2°, which is converted into a unitless value of 0.05 through trigonometric calculation. If 0.05>0.02, the data transmission cycle will be shortened from 2 hours to 1 hour.

[0050] Furthermore, the 4G communication module,...

Embodiment 3

[0053] Further, see image 3 , the Beidou communication module will encapsulate the tilt angle data into a Beidou short message, and the communication protocol it uses is not compatible with the remote monitoring platform. Therefore, a protocol conversion module is set at the receiving end of the remote monitoring platform to convert multiple Beidou short messages into a data format recognizable by the remote monitoring platform.

[0054] The improvement of this embodiment is that only a small amount of modification is made to the algorithm of data reception of the remote monitoring platform, so as to realize the reception and conversion of multiple Beidou short messages, and improve the practicability.

Abstract

The invention relates to an intelligent tower state monitoring terminal based on Beidou and 4G dual-mode communication. The intelligent tower state monitoring terminal comprises a shell, a 4G antenna,a Beidou antenna, a sensor and a processor, wherein the 4G antenna and the Beidou antenna are arranged on the surface of the shell, and the sensor and the processor are arranged in the shell. A monitoring period is set in the processor, and the processor starts the sensor regularly according to the monitoring period. After the sensor is started, a plurality of inclination angle data of the towerare continuously collected and sent to the processor. A data transmission period and a second threshold value used for judging whether early warning is needed or not are set in the processor. The processor judges whether the inclination angle value exceeds a second threshold value or not, if the inclination angle value exceeds the second threshold value, the processor immediately sends early warning information to the communication module, and the early warning information comprises inclination angle data; otherwise, the processor sends inclination angle data to the communication module at regular time according to the data transmission period. The communication module sends the received data to a remote monitoring platform through a 4G antenna or a Beidou antenna.

Description

technical field [0001] The invention relates to an intelligent monitoring terminal and method for tower status based on Beidou and 4G dual-mode communication, and belongs to the technical field of power equipment monitoring. Background technique [0002] The tower is an important basic structure of the transmission line of the power system. Knowing the status of the tower in real time is of great significance for ensuring the safe and stable operation of the power system. In the past, relying solely on manpower to conduct regular inspections and manual observations on towers not only has low work efficiency, inconvenient operation, huge labor and maintenance costs, but also makes it difficult to find hidden faults in towers. [0003] Therefore, in recent years, the intelligent monitoring technology of transmission line towers has developed rapidly. Among them, the technical solution of using sensors and mobile communication technology to realize online monitoring of tower s...
