Embodiment Construction

[0020] The technical solutions of the present invention will be described in further detail below through specific implementation methods.

[0021] A serial port communication method based on generator set historical records, the method comprises the following steps:

[0022] Step 1: Build a data model of the history content

[0023] The data model includes record type, record label, record value, record alarm upper limit value, record alarm lower limit value, record date and record time; assign and sort addresses to each data, and allocate memory space to each data.

[0024] Wherein, the record type includes shutdown alarm, trip alarm and trip shutdown alarm; the record label includes the set index number of event name, the record date includes record year, record month and record day, and the record time includes record hour , record minutes, record seconds;

[0025] The address sorting method of each data is: 1 record type, 2 record label, 3 record value, 4 record alarm u...

Abstract

The present invention provides a generator set historical record based serial port communication method. The method comprises the following steps: step 1: establishing a data model of historical record content, wherein the data model comprises a record type, a record number, a record value, a record high alarm limit value, a record low alarm limit value, a record date, and record time; assigning an address to each piece of data and sorting, and assigning memory space to each piece of data; step 2: establishing a historical record communication data packet, wherein the historical record communication data packet comprises historical record reading and historical record clearing; historical record reading comprises sending and receiving, and historical record clearing comprises sending and receiving; and step 3: implementing communication, wherein a generator set controller reads one or more historical records from the communication data packet in step 2.

Description

technical field [0001] The invention relates to a serial port communication method, in particular to a serial port communication method based on the history records of generator sets. Background technique [0002] Serial communication based on hardware circuit design commonly used three kinds of RS232, RS485, RS422, according to different needs to choose different serial communication methods. The most commonly used and most common software-based design is the Modbus serial port communication protocol. Since the generator set communication industry has its common and special features, the common monitoring data can use the Modbus serial port communication protocol. As for the historical records of generator sets, the amount of data is complex and numerous. In the process of communication, it will inevitably take a lot of time and energy to organize and process it with a general communication method, and it is also prone to errors. [0003] In order to solve the above exist...
