Hardware id identification method of communication module of electricity consumption information collection terminal

Abstract

The invention discloses an identification method for hardware ID of a communication module of an electricity information collecting terminal. According to the identification method, hardware ID identification pins of the communication module are connected to an AD sampling port and a level control circuit respectively; a microprocessor is adopted for implementing level pull-up control and level pull-down control on each hardware ID identification pin of the communication module through the level control circuit; AD sampling is carried out on the hardware ID identification pins of the communication module respectively, and the sampling results are compared with the set threshold to obtain the result of 0 or 1; finally, the result generated by each hardware ID is judged, wherein the hardware ID identification pin with the 00 result is in the level pull-down state, the hardware ID identification pin with the 10 result is in the suspending state, and the hardware ID identification pin with the 11 result is in the level pull-up state, so that the hardware ID of the communication module is obtained. The identification method can accurately and quickly acquire hardware ID of most existing communication modules, and is good in compatibility and easy to implement.

Description

technical field [0001] The invention relates to a hardware ID identification method, in particular to a hardware ID identification method of a terminal communication module for collecting electricity information. Background technique [0002] Due to the lack of clear technical specifications for design guidance, the hardware ID circuit standards of the communication modules designed by various electricity information collection terminal manufacturers are not uniform. Some have 5-digit hardware IDs, some have 6-digit hardware IDs, and some have hardware ID identification pins. It is level pull-up mode, some hardware ID identification pins are level pull-down mode, some hardware ID identification pins are in a floating state, and some communication module hardware ID identification pins need a circuit on the power consumption information collection terminal Cooperate to identify. At present, there is no universal, effective, and highly compatible way to correctly obtain the h...
