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

[0064] Embodiment 1: As shown in Figure 2, the method for realizing remote data measurement in the present invention includes:

[0065] S21: Configure the gateway;

[0066] 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 terminal metering equipment connected (for example: electric meter, water meter, gas meter, etc.), so as to achieve The purpose of a gateway to access different types of terminal metering equipment.

[0067] First, set a number of port (channel) communication protocols according to the type of terminal metering equipment that the gateway may access: protocol command words (that is, the command words used by the gateway to control the metering equipment), communication rate, and minimum Parameters such as response time and maximum data length are set separately. Each group of port (channel) communication protocol corresponds to a protocol number, and a ...

Embodiment 2

[0077] Embodiment 2: When configuring the gateway in Embodiment 1 of the present invention, the network identification of the remote server (such as the IP address in the Ethernet, the telephone number in the GPRS network, etc.) and the network identification of the gateway can also be determined according to the network situation. , Configure the parameters such as active timing collection / reporting cycle of data. After this configuration, the gateway can work in two modes: "server command" and "automatic collection / sending":

[0078] Take Ethernet as an example. When the gateway is in the server command working mode, the data collection and reporting of the terminal equipment by the gateway 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 conn...

Embodiment 4

[0092] Embodiment 4: The gateway may also include a working mode unit. By configuring the network identification of the remote server and the network identification of the gateway in the working mode unit of the gateway, the gateway can work in the "server command" mode, and the working mode of the gateway can also be further configured The active timing collection / reporting cycle parameters of the data in the unit makes the gateway work in the "automatic collection / sending" working mode.

[0093]Further, the gateway can send a data collection request to the terminal metering device according to the data collection instruction issued by the remote server received by the working mode unit; and after processing and receiving the data sent by the terminal metering device, according to the aforementioned working mode unit The report instruction in the system will report the data to the remote server to complete the remote data measurement; the gateway can also send data collection req...

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 present invention relates to data measurement technology, in particular to a method and system for remote data measurement. 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 functions are increasingly being used in control systems. There are more and more communicable devices in the control system, and the distribution is becoming more and more dispersed. The coordinated management of system devices based on communication networks has become an unavoidable trend and direction. And the network technology in the field of communication and industrial control, including various fieldbus technologies, industrial Ethernet, wireless network technology, etc., has been comprehensively and widely used in the current control system...
