Embodiment 1

[0066] figure 1 It is a schematic flowchart of a communication control method provided in Embodiment 1 of the present application.

[0067] Such as figure 1 As shown, it is a communication control method described in Embodiment 1 of the present application, which is applied to the feeder terminal device FTU, and the method includes the following steps:

[0068] Step S101, receiving data sent by multiple sensors.

[0069] In the embodiment of the present application, the sensor is a two-remote type, which can complete remote control and telemetry (collection volume, alarm), detect the collection volume on the line, and transmit the collection volume to the background of the main station for processing.

[0070] In the embodiment of the present application, FTU (FeederTerminalUnit, feeder terminal device) receives the data sent by the sensor through radio frequency, and then contacts with the background master station through the SIM card of the mobile phone. The advantage of ...

Embodiment 2

[0085] figure 2 It is a schematic flowchart of a communication control method described in Embodiment 2 of the present application.

[0086] Such as figure 2 As shown, it is a communication control method described in Embodiment 2 of the present application, which is applied to sensors, and the method includes the following steps:

[0087] Step S201, receiving the standard time and timing instruction sent by the feeder terminal device FTU.

[0088] Step S202, setting an initial value of the current time according to the standard time.

[0089] In the embodiment of this application, the current time of each sensor is calculated from the time of power-on, which may be inconsistent with the standard time of the FTU, so it is necessary to set the respective current time according to the standard time sent by the FTU in order to calculate the sending time.

[0090] Step S203, calculating and storing the sending time slice according to the initial value of the current time and ...

Embodiment 3

[0108] image 3 It is a schematic diagram of an application flow of a communication control method described in Embodiment 3 of the present application.

[0109] combine image 3 , the specific application of the communication control method described in the third embodiment of the present application will be described in detail.

[0110] Step S301: The sensor detects whether there is a carrier within the communication range with the feeder terminal device.

[0111] Step S302: The sensor sends data to the feeder terminal device when it detects that there is no carrier within the communication range with the feeder terminal device.

[0112] Step S303: The feeder terminal device receives data sent by multiple sensors.

[0113] Step S304: The feeder terminal device acquires the number of sensors corresponding to the data and the identifier of each sensor according to the amount of data received.

[0114] Step S305: The feeder terminal device generates a timing calibration ins...

Abstract

The embodiment of the invention discloses a communication control method and a communication control device. The method is applied to a feeder terminal unit (FTU), and comprises the steps of receiving data transmitted by a plurality of sensors; acquiring the quantity of the sensors corresponding to the data and the identifier of each sensor according to the received data; generating a time correcting command according to the quantity of all sensors and the identifier of each sensor; and transmitting standard time and the time correcting command to all sensors. According to the method, the time correcting command is generated and transmitted to the sensors, the sensors compute transmission time according to the time correcting command and the current time and store, and thereby the fixed periodical transmission time is formed; the transmission can be performed according to preset time slices, the situation that a plurality of sensors transmit data in order is ensured, the success rate of data transmission is improved, meanwhile the communication time and the power consumption of the sensors are reduced.

Description

technical field [0001] The present application relates to the technical field of power grids, in particular to a communication control method and device. Background technique [0002] The power system is the backbone of all economic activity. With the rapid development of the country's economy, the demand for energy has increased significantly, and the country has increased investment in power grid construction. At the same time, the demand for monitoring and measurement of the power grid is also increasing. This is not only the need for the development of the power industry's own management level, It is also the need of production and life in modern society. [0003] In power distribution management, once a ground fault occurs in a line, it will not only cause very serious accidents, such as: voltage rise and breakdown of connected lines, sudden change of fault phase current, pedestrian electric shock, etc., but also greatly reduce the quality of power supply. At the same...
