Abstract
The utility model provides a secondary water supply system based on a power line carrier. The secondary water supply system comprises a device centralized control center, a power line carrier modulator-demodulator 1, a power grid, a power line carrier modulator-demodulator 2 and a controlled terminal. The device centralized control center is electrically connected with the power line carrier modulator-demodulator 1 in two ways. The power line carrier modulator-demodulator 2 is electrically connected with the controlled terminal in two ways. The controlled terminal comprises a secondary water supply device, an electronic control valve, a water pump motor, a frequency converter and other devices. Corresponding expansion can be carried out as required. By means of the secondary water supply system, remote data transmission and device centralized control can be achieved.
Description
Technical field
The utility model relates to secondary water supply system, is specifically related to a kind of secondary water supply system based on power line carrier.
Background technology
The common alleged secondary water-supply of people, the unit of referring to or individual supply water city public water supply or self-built facility through storing, pressurizeing, and by pipeline, supply user or personal form again, and therefore, secondary water-supply is the only selection mode of current high-floor feedwater.
Current in secondary water supply system, the control of equipment is local control substantially, or point-to-point remote monitoring mode, for wireless communication mode, place not having wireless network to cover, cannot realize, and the main infield of current secondary supply equipment is basement pump house, wireless signal coverage scale is low, cannot realize transmission of wireless signals; For wire communication mode, need the special netting twine of laying, for user's pump house, do not lay netting twine, or lay netting twine inconvenience, cannot realize remote monitoring function.
Power line carrier communication is to take the communication of power system of the transmission medium that transmission line of electricity is carrier signal.Because transmission line of electricity possesses very firmly braced structures, and set up 3 above conductors (generally having three-phase good conductor and one or two aerial earth wire), so when power line is carried power current, the transmission carrier signal of using, not only economy but also very reliable.This comprehensive utilization becomes the preferential peculiar means of communication adopting of all power departments in the world already.
Utility model content
?the utility model aims to provide a kind of secondary water supply system based on power line carrier, realizes the remote monitoring of secondary water-supply equipment and the centralized Control of many complete equipments.
To achieve these goals, the utility model adopts following technical scheme:
A kind of secondary water supply system based on power line carrier, comprise equipment centralized-control center, power line carrier modem 1, electric power network, power line carrier modem 2 and controlled terminal, described equipment centralized-control center and two-way electrical connection of described power line carrier modem 1, described power line carrier modem 2 is electrically connected to described controlled terminal is two-way, and described controlled terminal comprises the secondary water-supply equipment that respectively overlaps, each electric control valve, each pump motor, each frequency converter.
The beneficial effects of the utility model are:
1, cost is low.This technology directly utilizes existing distribution network as transmission line, need not additionally connect up, and has greatly reduced the investment of network, has reduced cost.
2, scope is wide.Power line is the network that coverage is the widest, and its scale is that other any networks are incomparable.PLC can be penetrated into each pump house like a cork, for monitoring and the centralized Control of secondary water-supply equipment provides feasible solution.
3, two-forty PLC can provide transmission at a high speed.At present, its transfer rate between 4.5m ~ 45mbps, is enough to support data in existing equipment monitoring and the needs of transmission of video according to equipment manufacturer's difference.
4, always online.PLC belongs to " plug and play ", dialing procedure that need not be loaded down with trivial details, and access power supply just equals to access network.
5, convenient.No matter in which corner of pump house, as long as the controller of equipment is connected in any electrical socket in pump house, just can have immediately the express network that PLC brings.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated:
Fig. 1 shows the circuit block diagram of the secondary water supply system of the utility model based on power line carrier.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of secondary water supply system based on power line carrier, comprise equipment centralized-control center (being Surveillance center), power line carrier modem 1, electric power network, power line carrier modem 2 and controlled terminal, described equipment centralized-control center and two-way electrical connection of described power line carrier modem 1, described power line carrier modem 2 is electrically connected to described controlled terminal is two-way.Described power line carrier modem 1 and power line carrier modem 2 can be the signal of telecommunication that can transmit on power line by digital signal modulated, also the signal of telecommunication transmitting can be demodulated into data signal in power line.
Described controlled terminal can comprise the secondary water-supply equipment that respectively overlaps, each electric control valve, each pump motor, each frequency converter and other equipment, can expand accordingly as required.Equipment centralized-control center can send instruction, controlled terminal is carried out to the function such as supervision, control of data, video etc., realizes remote transmission and the centralized Control to equipment of data.
