Embodiment 1

[0015] Embodiment 1: with reference to attached figure 1 ----Wireless remote transmission M-BUS system. This method of data remote transmission needs to apply for this service at China Mobile or China Unicom. The data remote transmission adopts a wireless method. Each M-BUS system uses a GPRS / GMS data remote transmission terminal. The speed of data remote transmission in this way It is much faster than the telephone MODEM, and all the data collected by real-time collection and M-BUS can be transmitted in the form of data packets. M-BUS collects the data of all the slaves connected to it, saves it in its own RAN, regularly communicates with the remote data center, sends the data to the data center, or receives the data sent by the data center.

Embodiment 2

[0016] Embodiment 2: with reference to attached figure 2 ----Pocket computer meter reading M-BUS system. Handheld computer reads the data, this method, the communication mode between handheld computer and M-BUS can have many kinds, can adopt RS-232, short-distance wireless communication, infrared communication and so on. The handheld computer can read and send data on the M-BUS host, and can also be carried out on the repeater. The advantage of this is that it can temporarily replace the PC for work. If an accident occurs in the local M-BUS system, this method can also be used to process data on each M-BUS repeater. The real-time nature of this data transmission method is relatively strong, and real-time data acquisition can be used.

Embodiment 3

[0017] Embodiment 3: refer to image 3 ----- Computer meter reading M-BUS system. For computers directly connected to M-BUS, it is suitable for living in the community’s own data collection charging system, or through the special line charging system of the computer and the bank, for the independent charging system of the community, the data does not need to be transmitted remotely, M-BUS host Receive PC data directly through the RS232 interface and send it to all slaves. The slave data returns to the PC via the M-BUS master, and the PC can directly collect and issue corresponding controls for all data.

[0018] For the remote system with dedicated line between PC and bank, in the system of this kind of community, it is enough to add another dedicated line for PC to connect, and the connection method is not limited.

Abstract

It consists of computer or palm computer or GPRS or wired MODEM or handwriting device, M-BUS host or salve machine or relay and power meter. Manager exchanges data through computer or palm computer or GPRS or wired MODEM or hand writing device with M-BUS host or relay. It changes the data into M-BUS bus protocol data; M-BUS host receives simultaneously feeding back data from slave machine or relay and through the same path returns to manager.

Description

Technical field: [0001] The invention relates to a remote data meter reading system, which is mainly used for data collection of electric meters, water meters, gas meters, fire-fighting and industrial instruments. Background technique: [0002] At present, in the existing data meter reading system, the data communication between the host computer and each data acquisition module or instrument mainly adopts remote transmission schemes such as pulse remote transmission and RS-484, which have many shortcomings in use. The main manifestations are: troublesome line construction, remote power supply and other problems, which seriously restrict the application of remote meter reading system, especially the technical problems of cumbersome data connection and remote power supply have not yet found an effective solution. Invention content: [0003] Design purpose: to avoid the deficiencies in the background technology, and provide a remote meter reading system that uses two twisted...
