Embodiment Construction

[0040] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] The embodiment of the present invention is realized like this, as figure 2 and image 3 Shown, a kind of design method based on GPRS concurrent survey batch terminal time, described method comprises the following steps:

[0042] (1) Query the online status of the terminals to be surveyed in batches from the front-end processor, and the offline terminals do not participate in the survey; the request command format for batch querying the online status of the terminals refers to the communication protocol organization of the master station, and the frame format for batch querying the ...

Abstract

The invention discloses a method for concurrently surveying terminal time in batch, comprising the following steps: (1) querying a front-end processor for the on-line state of terminals to be surveyed in batch, wherein off-line terminals are not surveyed; (2) applying for obtaining the transmission lock of the on-line terminals, wherein the terminals failing in applying for the lock are not surveyed; (3) circularly organizing time request commands of the surveyed terminals by a send-thread, and transmitting the time request commands to a corresponding terminal by the front-end processor; (4) acquiring the current time of the system by each terminal, and organizing response data to be forwarded to a master station query module by the front-end processor; (5) receiving the response data of each terminal by a receive-thread, and notifying an analysis response thread; (6) analyzing the received response data by the analysis response thread, and extracting terminal time; and (7) releasing the transmission lock of the terminal finishing analysis. The method can find the problem of system time errors of an accessed terminal in an electric energy acquisition system in time.

Description

technical field [0001] The invention belongs to the technical field of electric power and communication, and in particular relates to a method for batch polling terminal time. Background technique [0002] With the transformation of the power system, the collection of power data will gradually abandon the traditional manual meter reading mode and adopt the remote terminal control meter reading method, and the meter reading data will be transmitted through GPRS / CDMA, Ethernet, telephone lines, serial channels, 230M, etc. The mode is transmitted to the master station system for analysis and application. In order to carry out data analysis applications and real-time monitoring of power consumption on the master station side, it is necessary to ensure the correctness and integrity of the power data on the master station side. The time scale of the data collected by the acquisition system is heavily dependent on the terminal. If the time scale of the data is wrong, the data will...
