Method and device for self-adapting of Baud rate in field of power monitoring

Abstract

The invention discloses a method and a device for self-adapting of Baud rate in the field of power monitoring. The method comprises the following steps of selecting a communication protocol; setting a Baud rate sequence; setting numbers of the Baud rate sequence; using the Baud rate with corresponding number in the Baud rate sequence to open a serial port; sending the protocol data to monitoring equipment; receiving the protocol data which is returned from the monitoring equipment; analyzing and judging the identifiability of the data; if the received data cannot be identified, closing the serial port, and adding the number of the Baud rate sequence with 1; and if the received data are uniform with the expected data, maintaining the Baud rate as the communication Baud rate. The method has the beneficial effect that the self-adapting of the Baud rate between control equipment and the monitoring equipment in the monitoring field can be realized. The device for realizing the self-adapting of the Baud rate in the field of power monitoring has the advantages that the structure is simple, and the comfortability of user experience is improved.

Description

technical field [0001] The invention belongs to the field of electric power monitoring, in particular to a method and device for realizing self-adaptation of baud rate in the field of electric power monitoring. Background technique [0002] At present, with the development of power monitoring technology and the continuous improvement of the requirements in the field of power monitoring, in the serial communication mode, more and more occasions require the function of baud rate self-adaptation. The control equipment can be compatible with multiple baud rate communications, but the monitoring equipment only supports one baud rate. The monitoring equipment can only operate correctly when the communication parties use the same baud rate for communication, so it must be set up according to the regulations. Corresponding baud rate, but the setting process is highly complicated and professional, and it is difficult for users to operate, which brings great inconvenience to popular u...

Problems solved by technology

The control device can be compatible with multiple baud rate communications, but the monitoring device only supports one baud rate. The monitoring device can only operate correctly when the two parties in the communication use the same baud rate communication, so it must be set up according to the regulations. Corresponding baud rate, but the setting process is highly complex, highly professional, and difficult for users to operate, which brings great inconvenience to popular use

In addition, in order for users to understand the size of the baud rate, it is necessary to clearly indicate the size of the baud rate used and the specific modification method in the monitoring equipment or the operation manual of the monitoring equipment. At the same time, professionals must participate in the setting and guidance , which greatly increases the cost of manpower, material resources and time, and increases the cost of use
