Abstract

The invention discloses an MBUS host communication circuit. The MBUS host communication circuit is provided for solving the problem that at present, software is usually used for recognition, the situation of non-response or downtime is prone to occurring, and consequently the meter searching accuracy and speed are affected badly. The circuit comprises a host processor and slave equipment; the MBUS-end of each slave device is connected with the analog-to-digital conversion end of the host processor, the MBUS-end of each slave device outputs a current signal during normal operation, so that the host processor obtains the total current value of all slave devices during operation, and the output current value is relatively fixed during normal operation of the slave devices; therefore, the number of the slave devices can be obtained according to the total current value, the function of recognizing the number of the slave devices through hardware is achieved, the influence of non-response or other problems possibly caused by recognizing the number of the slave devices through software is avoided, and the meter searching accuracy and speed of MBUS communication are further improved.

Description

technical field [0001] The present application relates to the field of intelligent instrument communication, in particular to an MBUS host communication circuit, method, device and medium thereof. Background technique [0002] In recent years, in the practical application of smart meters, the remote meter reading system (symphonic mbus, MBUS) host communication circuit is usually used for remote data collection and interaction, which uses the MBUS bus to send voltage signal data to slave devices and receive The current signal data of the slave device can be recognized and processed after being converted into a voltage signal, so as to realize functions such as remote meter reading. Identify the number of machine devices. [0003] At present, the MBUS host communication circuit usually uses software to identify the number of slaves, but because the software is prone to non-response or other problems, it will have a negative impact on the accuracy and speed of the MBUS host c...
