Problems solved by technology
[0002] In the field of substations, sensor nodes work outdoors for a long time, and it is easy to disconnect the sensor node due to the failure of the line, interface or sensor node itself due to wind, sun and rain.
[0003] In the existing technology, the sensor is often delayed due to offline maintenance, which brings trouble to the detection of substation environmental data, so that the environmental parameters of the substation cannot be monitored, which affects the safety of the substation

Embodiment Construction
[0035] The present invention will be further described below in conjunction with the drawings and embodiments:
[0036] Such as Figure 1-2 As shown, in the first embodiment of the present invention, a sensor disconnection detection method is provided, and the method includes:
[0037] Step S1: The background server receives the first service data periodically sent by the sensor node, and records the first service data and the first receiving time of the first service data; the first service data includes the sensor node constructing the The first construction time of the first business data;
[0038] Step S2: In response to receiving the first service data, the background server sends a receipt for the first service data to the sensor node; the receipt receipt includes the first service data of the first service data. A package construction time and the first reception time when the background server receives the first service data;
[0039] Step S3: The sensor node recognizes that...

The invention discloses a sensor offline detection method, which relates to the field of power systems, and comprises the following steps that: firstly, a background server receives first service datasent by a sensor node at regular time, and sends an incoming message receipt for the first service data to the sensor node; then, when the sensor node recognizes that sensor data acquisition is wrongor the document receipt is not received within a preset time length, the service cache is emptied, a restart record is sent, and the sensor node is restarted; and finally, whether the sensor node isoffline or not is judged according to the current system time, the first receiving time, whether a restart record is reached or not and a preset sensor restart waiting time length. Whether the sensornodes are offline or not can be effectively judged so that maintenance personnel can maintain the related offline sensor nodes, acquisition of environmental data of the transformer substation can be guaranteed, and safety of the transformer substation can be guaranteed.
Description
Technical field [0001] The invention relates to the field of substations, in particular to a method for detecting sensor disconnection. Background technique [0002] In the field of substations, sensor nodes work outdoors for a long time, and it is easy to cause the sensor node to be disconnected due to wind, sun, rain, and line, interface or sensor node failures. [0003] In the prior art, sensors are often delayed for maintenance due to disconnection, which brings trouble to the detection of environmental data in the substation, which makes the environmental parameters of the substation unable to be monitored and affects the safety of the substation. Summary of the invention [0004] In view of some of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a sensor disconnection detection method, which aims to effectively determine whether a sensor node is disconnected, so that maintenance personnel can maintain related disconn...
