Problems solved by technology

[0003] At present, the data of metering equipment such as electric meters is usually recorded manually, and the recording frequency is different according to the requirements of each user. In some places with strict management, the operation management personnel record the data once a day, but most units record once a month. data, but the monthly recording time is not uniform. For example, the previous month is recorded at the beginning of the month, and this month is recorded at the middle of the month. These are the troubles caused by manual operation, and they are also unavoidable problems of manual operation.
In addition, if the sub-item measurement of statistics is carried out, the number of measurement equipment will increase sharply, and it will be more difficult to obtain all data by manual meter reading

Embodiment 1

[0044] Embodiment 1: as figure 2 As shown, the present invention realizes the method for remote metering of data comprising:

[0045] S21: configure the gateway;

[0046] The user configures the data transmission format (communication protocol) of each access port (channel) in the gateway locally or remotely according to the type of connected terminal metering equipment (such as electricity meter, water meter, gas meter, etc.), so as to achieve The purpose of a gateway to access different types of terminal metering equipment.

[0047] First, set several port (channel) communication protocols according to the type of terminal metering equipment that the gateway may access: the protocol command words included in the communication protocols of these ports (that is, the command words for the gateway to control the metering equipment), communication rate, minimum Parameters such as response time and maximum data length are set separately. Each group of port (channel) communicat...

Embodiment 2

[0057] Embodiment 2: Embodiment 1 of the present invention, when disposing gateway, also can according to the situation of network, to the network identification (such as the IP address in Ethernet, the telephone number in GPRS network etc.) of far-end server, the network identification of gateway , Data active timing collection / reporting cycle and other parameters are configured. The gateway configured in this way can work in two modes: "server instruction" and "automatic collection / send":

[0058] Take Ethernet as an example. When the gateway is in the server command working mode, the gateway's data collection and reporting to the terminal equipment are controlled by the remote server. Because this mode requires two-way communication between the remote server and the gateway, the remote server needs to know the network identifier of the gateway in the network, that is, the IP address of the gateway, and each gateway must be directly connected to the WAN and have a WAN IP a...

Embodiment 4

[0072] Embodiment 4: the gateway can also include a working mode unit, by configuring the network identifier of the remote server and the network identifier of the gateway in the gateway working mode unit, the gateway can work in the "server instruction" mode, and the gateway working mode can also be further configured The active timing collection / reporting cycle parameters of the data in the unit make the gateway work in the "automatic collection / send" working mode.

[0073] Further, the gateway can send a data collection request to the terminal metering device according to the data collection command issued by the remote server received by the working mode unit; and after processing the data sent by the terminal metering device, according to the aforementioned working mode unit The reporting command in the module will report the data to the remote server to complete the remote data measurement; the gateway can also regularly send the data collection request to the terminal me...

Abstract

The method comprise: a) the gateway sends the data collection request to the terminal measuring device; b) according to the received data collection request, the terminal measuring device sends the collected data to said gateway; c) said gateway saves the received data, and packs the saved data to form data frame matching the network protocol, and reports it to the far end server; d) the far end server de-packs the received data frame, and saves the data. The invention also provides a data remotely measuring system.

Description

technical field [0001] The invention relates to data metering technology, in particular to a method and system for remote data metering. Background technique [0002] At present, in the field of digital communication and automatic control, more and more computer chips are embedded in electromechanical equipment. Programmable digital controllers have replaced analog controllers; "smart" devices with digital communication capabilities are also increasingly used in control systems. The number of communication devices in the control system is increasing, and the distribution is becoming more and more scattered. It has become an unavoidable trend and direction to realize the coordination and management of system devices based on the communication network. The network technologies in the field of communication and industrial control, including various field bus technologies, industrial Ethernet, wireless network technologies, etc., have been comprehensively and widely used in the...
