Embodiment Construction

[0021] A frame-by-frame interconnection transmission method in an electricity consumption information collection system, such as figure 1 shown, including the following steps:

[0022] Step 1. In this embodiment, the frame length of a single frame after framing is 100 bytes as an example to illustrate the principle and implementation method of framing interconnection. First, according to the transmission mechanism, set the frame length to 100 bytes, including 8 control bits and 92 data bits, of which 8 control bits are used for data transmission function control, and one of them is taken as the "frame flag bit" for Indicates that this frame is a complete frame or has a subsequent frame; the "frame flag" can be marked with letters or numbers. In this embodiment, the first identifier uses "91", which means a complete data frame, that is, no frame; The third identifier adopts "B1, B2...", indicating that there is a subsequent frame; the second identifier adopts "92", indicating ...

Abstract

The invention discloses a framing and interconnection transmitting method in an electricity utilization information collecting system. The framing and interconnection transmitting method in the electricity utilization information collecting system comprises the following steps: setting the length of a single frame after framing according a transmitting mechanism, and expressing that the frame is a complete frame or a subsequent frame by 'frame tagging bits'; and reading descending data of electricity quantity, electric energy meter information and the like in an intelligent electric energy meter into a buffer region of a collector, judging the completeness of a data frame by control codes, and assembling the data frame in the collector. The electric energy meters manufactured by different meter manufacturers have different framing lengths, but the integrity of the data frame can be determined only according to the tagging bits, and the frame losing and frame assembling errors can be prevented, so that the collector can be suitable for the electric energy meters of all manufacturers, and the interconnection and communication properties with the electric energy meters are improved. By adopting the framing interconnection transmitting method in the electricity utilization information collecting system, a low-voltage electricity utilization information collecting system is introduced for the framing transmitting method, so that the ascending data constant-length framing transmission of the collector is realized, and the transmission velocity and the link utilization ratio are improved.

Description

technical field [0001] The invention relates to a data transmission method, in particular to a frame-by-frame interconnection transmission method in an electricity consumption information collection system. Background technique [0002] The power consumption information collection system of power users is a system for collecting, processing and real-time monitoring of power consumption information of power users. It is mainly composed of five parts including the master station of the acquisition system, the remote communication channel, the concentrator, the local communication channel, and the metering device. The local communication channel is the key to realize the real-time and reliable collection of power consumption information of power users. Generally, low-voltage power line carrier communication technology, micro-power wireless communication technology or RS485 bus communication technology is used for local communication channel construction. [0003] In the power...
