Problems solved by technology

[0003] At present, in the data acquisition master station system of public utility commodities, the B / S architecture is mainly used to design, that is, the design is based on this widely used system architecture. However, although this method is easy to operate, it is aimed at sales As far as electrical systems are concerned, it is not a fully applicable and convenient structure
In particular, technicians have noticed that it has more and more defects. For example, the main problem is that after the communication between the user and the master station is established, the data interaction is performed through the WEB page. For some network bandwidth comparisons When used in a small area, it takes a long waiting time for the user to download data, graphics or tables during the communication process, and it cannot be guaranteed that each communication is valid, that is, connection errors and incorrect information may occur. security issues
Or, for different types of users, it is impossible to meet their different performance requirements, the system must rely on maintenance personnel to manually upgrade and troubleshoot, and there are key problems such as clock inconsistency, so it needs to be improved

Embodiment 1

[0062] refer to figure 1 , the data acquisition system for the electricity selling system of the present invention, which includes a client application end 1, a server end 2 and an electricity selling terminal 3, and the client application end 1 is connected to the electricity selling terminal 3 through a server end 2, wherein the server end 2 includes:

[0063] WEB_SERVICE port 24, the server end 2 communicates with the client application end 1 and the electricity sales terminal 3 through the WEB_SERVICE port 24 to receive and send data information, this port is not affected by any communication protocol restrictions and physical bandwidth, but in Need to set up its place hardware environment when using, the processor 21 of server end 2 of the present invention has solved this problem;

[0064] A storage unit 22 for storing received data information, preferably an EEPROM memory;

[0065] The data encryption control terminal 23 that decrypts and encrypts these data informati...

Embodiment 2

[0085] refer to figure 2 , the present invention further proposes a self-upgrading electricity sales system based on Embodiment 1, which includes a server terminal 2, an electricity sales terminal 3 and several power collection terminals 4 provided with client application terminals 1, and the power collection terminal 4 is connected to The server end 2, the server end 2 is connected to the electricity selling terminal 3, wherein the server end 2 includes:

[0086] WEB_SERVICE port 24, the server end 2 communicates with the power collection terminal 4 and the power sales terminal 3 through the WEB_SERVICE port 24 to receive and send data information;

[0087] A storage unit 22 for storing the received data information;

[0088] A data encryption control terminal 23 that decrypts and encrypts data information when the data information is received and sent; and

[0089] The processing unit 21 is coupled to the storage unit 22 and the data encryption control terminal 23 to proc...

Embodiment 3

[0104] The present invention also proposes an automatic upgrading method for a self-upgrading electricity sales system, which includes the following steps:

[0105] 1) Send an update request to the server 2 through the thin client unit 11 of the client application terminal 1. In a preferred embodiment of the present invention, the thin client unit 11 will set a time period, and send Give server 2 an update data request; at the same time, it should be understood that, in order to maintain the validity and real-time performance of the data obtained from electrical measurement, periodic data monitoring is carried out during the data transmission process. If the energy information fluctuates, For example, when the grid voltage is unstable or the three-phase power imbalance is wrong, the terminal 3 should be able to obtain the information through the server to make a timely judgment;

[0106] 2) The processing unit 21 of the server 2 receives and verifies the update request, and se...

Abstract

The invention discloses a data acquisition system for an electricity vending system. The data acquisition system comprises a client application end, a server end and an electricity vending terminal, wherein the client application end is in communication and connection with the electricity vending terminal through the server end. The invention further discloses a self-upgrade type electricity vending system utilizing the data acquisition system and an automatic upgrading method thereof. The server end of the data acquisition system disclosed by the invention can provide the access to a main station terminal database, encryption service and the like through a provided WEB-SERVICE interface so as to respond to different requests of a client; and after a server receives the request, corresponding data or parameters can be obtained, and an electricity vending TOKEN code is further required in an encrypted way. According to the data acquisition system disclosed by the invention, mounting and use of the client can be facilitated; and simultaneously, data communication between the client and the server is of required data which is in TOKEN way purely, picture graphs, tables or other unrelated stream media data are not involved, and data traffic and bandwidth are saved.

Description

technical field [0001] The present invention relates to public utility commodities (such as water, electricity, gas, etc.), especially to the technical field of grid power prepaid metering. More specifically, the present invention relates to a data acquisition system for a power sales system that realizes novel data acquisition , and an automatic upgrade prepaid electricity sales system designed based on the data acquisition system, and further relates to a method for automatic system upgrade of the electric meter reading system based on thin client technology. Background technique [0002] The B / S (browser / server) architecture is the browser / server architecture, which is a change or improved structure of the original C / S (client / server) architecture with the rise of Internet technology. Under this structure, the user interface is implemented through the www browser, and a very small part of the business logic is implemented on the front end (Browser), but the main business ...
