Problems solved by technology

[0003] The traditional data synchronous acquisition method is generally a GPS synchronization method. The GPS synchronization signal is received by the GPS receiver and sent to the acquisition device for acquisition synchronization after corresponding processing. This method needs to provide an additional GPS receiver, which not only increases the cost , and when the system design becomes complicated, the purpose of the present invention is to solve the problem of sensor synchronization, integration and integration of acquisition and communication

Embodiment 1

[0025] as attached figure 1 The present invention provides a method for synchronous acquisition of sensors in the field of electric power Internet of things, the method comprising the following steps:

[0026] Step (1): The base station scheduling module sends the broadcast frame BCH every second, and the frame information includes the SYN frame sequence number;

[0027] Step (2): When the base station scheduling module receives the terminal sensor access request, it searches the system whitelist for the existence of the sensor ID, and if it exists, allocates the corresponding DRX time to the sensor;

[0028] Step (3): The terminal module communication module, according to the preset communication protocol, receives the BCH broadcast signal and DRX scheduling of the base station. When receiving the BCH signal, the terminal module will generate a GPIO pulse signal to the sensor and transmit it BCH broadcast frame number SYN and DRX value to the sensor;

[0029] Step (4): The ...

Embodiment 2

[0041] as attached figure 1 The present invention provides a method for synchronous acquisition of sensors in the field of electric power Internet of things, the method comprising the following steps:

[0042] Step (1): The base station scheduling module sends the broadcast frame BCH every second, and the frame information includes the SYN frame sequence number;

[0043] Step (2): When the base station scheduling module receives the terminal sensor access request, it searches the system whitelist for the presence of the sensor ID. If it exists, it allocates the corresponding DRX time to the sensor. If it does not exist, it accesses it through the server Request data to be recorded and computer generated request data forms;

[0044] Step (3): The terminal module communication module, according to the preset communication protocol, receives the BCH broadcast signal and DRX scheduling of the base station. When receiving the BCH signal, the terminal module will generate a GPIO pu...

Abstract

The invention relates to the technical field of electric power Internet of Things, in particular to a sensor synchronous collection method in the field of electric power Internet of Things, which comprises the following steps: a base station scheduling module sends a broadcast frame BCH per second, and frame information comprises an SYN frame sequence number; when the base station scheduling module receives a terminal sensor access request, the existence of the sensor ID is searched in the system white list, and if the sensor ID exists, the corresponding DRX time is distributed to the sensor; and the terminal module communication module is used for receiving the BCH broadcast signal and DRX scheduling of the base station according to a preset communication protocol when the BCH signal is received. The synchronization, collection and communication of the sensor can be integrated through design, an extra data synchronization module does not need to be added, the data synchronous collection precision within the us level can be achieved, the cost and precision are better compared with a traditional GPS synchronization mechanism, and compared with the complex design of a transmission system, the design is more precise and compact, and the cost is low. The industrial cost is further reduced.

Description

technical field [0001] The invention relates to the technical field of electric power internet of things, in particular to a method for synchronous acquisition of sensors in the field of electric power Internet of things. Background technique [0002] With the rapid development of the power Internet of Things, various sensors have come out one after another, how to correctly upload their data to the cloud, especially for synchronous sensors, the sensors need to collect data at the same time and upload the data at the same time, such as three-phase electrical parameter data Acquisition, the three sensors are located in A, B, and C phases, and collect data synchronously. [0003] The traditional data synchronous acquisition method is generally the GPS synchronization method. The GPS synchronization signal is received by the GPS receiver and sent to the acquisition device for acquisition synchronization after corresponding processing. This method needs to provide an additional ...
