specific Embodiment approach

[0097] The present invention combines the attached Figures 1 to 8 The specific implementation of its technical scheme is described as follows:

[0098] 1. Without external intervention (without the intervention of machine configuration equipment and the arrival of server commands), the concentrator will perform periodic meter reading and timing meter reading tasks according to the user's preset settings.

[0099] The execution process can refer to the above task flow introduction and Figure 4 , Figure 5 .

[0100] Second, if the concentrator is running and a command frame from the server arrives at this time, due to the task priority, the running periodic meter reading task process and scheduled meter reading task process will be suspended and placed in a ready state. In this way, user operations on the server side will get real-time responses.

[0101] The server command frame parsing process can refer to the above task process introduction and image 3 .

Abstract

The invention relates to a multi-access concentrator used in a gas burning system and a service method therefor. The multi-access concentrator of the invention comprises a microcontroller LPC2114 chip, a serial port UART0, a serial port UART1, a communication interface RS485, a GPRS module and an Ethernet interface; the concentrator realizes communication with a meter and an administration server by the serial port UART0 and the serial port UART1 respectively. The service method of the invention comprises the following steps: system startup task, server command frame analyses task, periodic meter-reading tasks, configuration of basic data of the concentrator and hook function flow in a real-time operation system. The invention features easy configuration, simple operation, convenience and flexibility and stable operation.

Description

technical field [0001] The invention relates to a concentrator and its service method, in particular to a multi-access concentrator used in a gas system and its service method. Background technique [0002] So far, automatic remote meter reading control system has been widely concerned and applied. Moreover, the Ministry of Construction stipulates that one of the necessary conditions for an intelligent community in the new era is a remote automatic metering system with three meters for water, electricity and gas. But for now, the application and feedback of the remote meter reading system that has been implemented are not optimistic. Various problems such as system instability, statistical data errors, equipment failures, and maintenance difficulties continue to emerge. [0003] In the design of the repeater link, due to the diversity of user needs and applications of different implementation units, the design schemes of various domestic meter reading systems (which have b...
