Embodiment 1

[0037] see figure 1 , figure 2 , the communication method of the Type II collector of the present embodiment, comprising the following steps:

[0038] Set the communication module of the collector to provide the MCU channel switching signal of the collector;

[0039] After the collector is powered on, it starts to wait to receive the data from the communication module, and selects to forward the received data to the 485 or infrared channel through the channel switching signal;

[0040] When the 485 or infrared channel has data reception, select whether to transmit the data to the communication module through the channel switching signal.

[0041] In practical applications, the following improvements can be made:

[0042] Set the communication module of the collector to also provide the MCU of the collector to receive valid signals; considering that 485 or infrared are half-duplex communication, in order to avoid errors, the received valid signal is used to control the seri...

Embodiment 2

[0045] see figure 1 , figure 2 , the communication method of the Type II collector of the present embodiment, comprising the following steps:

[0046] S1: After power-on, the type II collector MCU starts to wait for receiving communication module or infrared channel data, and the channel switching signal defaults to select the infrared channel to connect with the communication module, and the default is valid when receiving a valid signal; the channel switching signal selects type II collector MCU Control IO port settings;

[0047] S2: If the communication module data is received, the channel switching signal selects the 485 channel to connect with the communication module, and immediately forwards the data to the downlink 485 channel synchronously, and waits for the completion of the forwarding or the response timeout;

[0048] S3: After the 485 channel sends data, if there is data returned, it is immediately forwarded to the communication module synchronously, and after t...

Embodiment 3

[0056] see figure 1 , figure 2 , corresponding to Embodiment 1, the communication system of the Type II collector of this embodiment includes:

[0057] The communication module is configured to provide a channel switching signal to the collector MCU;

[0058] The collector MCU is used to wait for the data received from the communication module after the collector is powered on, and selects to forward the received data to the 485 or infrared channel through the channel switching signal; it is also used when the 485 or infrared channel has data to receive, Select whether to transmit data to the communication module through the channel switching signal.

[0059] In practical applications, the communication module is also set to provide the collector MCU to receive valid signals to avoid half-duplex communication conflicts;

[0060] The collector MCU is used to wait for the data from the communication module to be received after the collector is powered on, and to select and f...

Abstract

The invention discloses a communication method of an II type collector. The method includes the following steps that a communication module of a collector is set in a mode that a channel switching signal is provided for the collector MCU; the collector starts to wait for receiving data of the communication module after being powered on and selects to transfer the received data to a 485 or infrared channel through the channel switching signal; when the 485 or infrared channel receives data, whether data are transmitted to the communication module or not is selected through the channel switching signal. Only a chip function pin of the communication module of the collector needs to be added simply, the collector MCU conducts processing according to the channel switching signal provided by the communication module and a received effective signal so that the infrared and 485 can conduct communication by sharing a first serial port of the communication module when conducting communication, and the collector MCU only needs to achieve channel switching, so that hardware cost is greatly lowered, and resource waste is avoided; meanwhile, the II type collector designed by the scheme is compatible of communication modules of any scheme, and development efficiency is improved.

Description

technical field [0001] The invention relates to the field of electric meter reading, in particular to a communication method and system for a Type II collector. Background technique [0002] As the construction of the electricity consumption information collection system of the State Grid Corporation enters the leading and upgrading stage, there is a meter reading method in the electricity consumption information collection system in the smart grid architecture. It is built with the type II collector by means of carrier or wireless communication. At the same time, for the convenience of maintenance, an infrared communication function is also added. Therefore, in general, when selecting an MCU for a Type II collector, at least an MCU with two serial ports is required. [0003] The type II collector has been developed to the present, and there are narrowband, OFDM, broadband, micropower wireless, Ethernet and other communication modules according to different communication m...
