Embodiment Construction

[0029] In the point-to-multipoint data acquisition mode, the automatic addressing method for instruments and meters will make automatic data acquisition more convenient. After adopting this method, the previous two-step process of finding the communication address manually and then collecting data can be completely abandoned, and can be designed to be completed automatically in one step.

[0030] After applying this method, in the point-to-multipoint data acquisition mode, the workflow is as follows: start the data acquisition program----automatically address the instruments and meters in the network---store these addresses----respectively Call these addresses for data collection.

[0031] The following takes the meter automatic reading system as an example to illustrate the application of this technology.

[0032] 1. Application examples of meter automatic meter reading system

[0033] The traditional meter reading method is to manually record the meter reading data in the ...

Abstract

The invention belongs to data collecting technology field of electron instrument meter. Pointing to the data collecting mode of point to multi-point, the invention is the automatic searching of the communication address of the instrument and the meters. The method is: the primary station uses broadcasting order addressing, the slave station uses random delay mode to replay; after the slave station receives the addressing order, there generates an integer less than a set integer T in random, the T is multiplied by a fixed time interval A, the result is the reply delay time of the slave station; after the primary sends out the addressing order, in Tí‡X time, it is in state of receiving data, completes part of the addressing task of the slave station; the primary station sends out order to the slave station which is addressed, thus the slave station doesn't response the broadcasting addressing order in the time DT; repeats the process, it can complete the addressing task to the slave station, the stop label is: after several times of sending addressing order, the slave station has no response. The invention can realize automatic addressing quickly, the invention is simple and convenient.

Description

technical field [0001] The invention relates to the field of data collection of electronic instruments and meters, and is suitable for an automatic addressing method in a point-to-multipoint data collection mode. Background technique [0002] 1. Market background [0003] At present, many smart instruments and meters have data communication ports, and smart instruments and meters exchange data with external devices through these communication ports. The external equipment can thus conveniently perform parameter setting, data acquisition and other operations on these instruments. For instruments and meters that need to exchange data, they often have multiple communication ports. Generally, most of them have one or multiple communication ports at the same time: RS-232 port, RS485 port, infrared communication port, wireless communication port, etc. If the data collection of these instruments is not completely one-to-one, but one-to-many, then in the program design of the inst...
