Embodiment Construction

[0035] The present invention has realized system index:

[0036] 1. Establish an efficient and real-time data collection platform based on cable TV network data transmission.

[0037] 2. In any case, the accuracy rate of reading power is greater than or equal to 99.9%.

[0038] 3. Working environment temperature for normal operation: -25°C-+55°C.

[0039] 4. System network speed: 100Mbps; computer remote communication channel speed: 64Mbps-2Mbps.

[0040] 5. Data retrieval response time is less than 3 seconds; screen call response time is less than 3 seconds.

[0041] 6. Since the main equipment of each component of the system is installed in the external environment, it should have a considerable ability to resist man-made and natural damage, as well as a considerable ability to resist impact and pollution flashover.

[0042] 7. In any one minute, the average load rate of the server CPU is less than or equal to 35%; the average load rate of the workstation CPU is less than...

Abstract

The invention discloses a side management terminal needed by a multi-network integrated intelligent grid and belongs to the field of intelligent grid management. The side management terminal comprises a CPU module, a closedown module, an acquisition module and the like, wherein an AC / DC conversion module, the closedown module, the acquisition module, an Ethernet module, a storage module and an indicator light module are connected with a CPU module respectively; the outlet of a Cable Modem module is connected with the inlet of the Ethernet module; the outlet of a CATV is connected with the inlet of the Cable Modem module; and the outlet of the closedown module and the acquisition module are connected with an electricity meter on a bus respectively. The device provides a plurality of data transmission ways, performs statistics on line in real time, transmits electricity data back to an electrical supply company, changes the electricity meter with single function to an electricity meter with multiple functions, and realizes functions of remote closedown and the like.

Description

technical field [0001] The invention belongs to the field of intelligent power consumption, and in particular relates to a multi-network fusion smart grid demand side management terminal. Background technique [0002] In the prior art, the transmission medium for meter data collection is RS485, power carrier, wireless transmission, or a combination of wireless modules and RS485. There are phenomena such as laying lines or packet loss and missed copying of transmitted data. The power supply company can only use the method of manually going to the scene to cut off the electricity for the unpaid electricity users, or the electricity users use high-value multi-function control electric energy meters. Every time the power supply company adjusts the electricity price settlement amount of electricity consumption, it needs to program separately to let the system master station execute a new program to make statistical data according to the new electricity price. Power data transmis...
