Embodiment Construction

[0015] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention, and provides a detailed implementation manner and a specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0016] like figure 1 , figure 2 As shown, a residential water or gas meter remote upgrade system includes a water / gas meter terminal 6, a 4G / 3G / 2G / NB-IoT network 4, and a service terminal 5 connected in sequence. The water / gas meter terminal is the CW-NBF IoT valve-controlled water meter produced by Liaoning Sikai Technology Co., Ltd., and the service terminal is the Sikai meter reading management system of Liaoning Sikai Technology Co., Ltd.

[0017] The water / gas meter terminal 6 adopts the MSP430FR6972 of the central processing unit TI company. The RDX and TDX pins of th...

Abstract

An external Flash is adopted for storing upgrade package data, on one hand, the storage space of a central processing unit of a water or gas meter is saved, on the other hand, due to the fact that the upgrade package data is erased when upgrade is not needed, upgrade interruption and accidental failure are caused, collapse of the system is avoided, and stability of programs of the water or gas meter is guaranteed. And the wireless module adopting the 4G / 3G / 2G / NB-IoT network can be flexibly replaced, so that the network reliability of the system is ensured under different requirements. The service terminal of the system supports a breakpoint resume function, even if the first upgrade fails, data downloading does not need to be completely carried out again in the second upgrade, the upgrade time is saved, and the communication cost is reduced. And the use of the meter is not influenced in the process of downloading the upgrade data packet. According to the invention, the inconvenience caused by manual near-end meter end upgrading and maintenance is greatly reduced, the rapidness and reliability of remote upgrading are ensured, and the maintainability of the meter and the accuracy and reliability of upgrading are enhanced; and the meter can perform normal metering in the upgrade package downloading process.

Description

technical field [0001] The invention relates to a remote upgrade system, in particular to a remote upgrade system for a residential water or gas meter. Background technique [0002] With the continuous improvement of living standards, urban residents have risen sharply, and the number of smart water and gas meters has increased rapidly. The service life of the watch is generally more than 7 years, and maintenance and upgrading are inevitable during this period. If the near-end upgrade is completely performed manually, a lot of manpower and material resources are required, which will bring great difficulties to the maintenance work. With the development of wireless technology and the maturity of network applications, remote upgrade technology has also been invented, but different from the existing remote upgrade system, the present invention is specially adapted for the remote upgrade scheme of water and gas meters. The single-chip microcomputer used in the meter generally ...
