Abstract
The utility model relates to a gas meter based on powerline carrier wave communication. The gas meter comprises a CPU and is characterized in that the CPU is electrically connected with a memorizer circuit and an LCD display module, and the CPU is further connected with a mains supply through a powerline carrier wave communication module. The gas meter is a gas metering device which achieves communication by means of a powerline. According to the gas meter, wire communication is achieved for all the metering data and the state information data of the meter through the powerline, the data are transmitted back to a backstage management system in real time or at regular times so that a gas company can monitor the operating state of each gas meter in real time, and then safety of gas using is guaranteed. Furthermore, due to the fact that wire communication of the gas meter can be achieved by means of the powerline, the troubles of other wire communication methods that wiring needs to be conducted specially are saved, and wire communication of the gas meter can be achieved as long as electricity is available.

Accompanying drawing 2 is the logic theory block diagram of power carrier communication module in the utility model.
Embodiment
As shown in Figure 1, 2, the utility model is a kind of gas meter, flow meter based on power carrier communication, comprise CPU, described CPU is electrically connected with memory circuitry and LCD display module respectively, and this CPU is also electrically connected with city by power carrier communication module, specifically by wire and connected plug, is directly inserted on socket or wiring board.Also comprise power carrier communication concentrator, this power carrier communication concentrator is connected with power carrier communication module by electric power networks, and this power carrier communication concentrator is also connected with host computer by GPRS or GSM network, thereby multiple gas meter, flow meters can be carried out to networking, and information is sent to host computer.
Wherein CPU is also electrically connected with temperature detecting module, thereby detect the operating ambient temperature of gas meter, flow meter, and CPU is also electrically connected with alarm interface and valve control module, thus in the situation that alarm detects gas leakage valve-off, that guarantees user uses gas safety.
Wherein power carrier communication module comprises power carrier chip, and this power carrier chip is electrically connected with memory circuitry, signal isolation system, filtering and frequency conversion system, signal coupling and amplification system respectively.This power carrier chip adopts modern VLSI (very large scale integrated circuit) and embedded processing technology, this power carrier chip is electrically connected with memory circuitry, signal isolation system, electric power system, filtering and frequency conversion system and signal coupling and amplification system respectively, signal isolation system is thoroughly isolated gas meter, flow meter and civil power, guarantees the safe operation of gas meter, flow meter.Electric power system is by conversions such as civil power process AC/AC and AC/DC, for whole system provides safe and reliable power supply.The high frequency analog signals that the existence of filtering and frequency conversion system makes it possible to propagate on electric power converts the digital signal that can be identified by single-chip microcomputer to and becomes a reality.The digital signal that the existence of signal coupling and amplification system makes it possible to be identified by single-chip microcomputer converts the high frequency analog signals that can propagate on electric power to and becomes a reality.
Using method of the present utility model is:
During use, by multiple gas meter, flow meters, the power carrier communication module by separately and power carrier communication concentrator couple together formation network by electric power networks, then by power carrier communication concentrator and host computer, realize wireless connections.Thereby can be regularly (for example interval 10 minutes once) operating ambient temperature of gas meter, flow meter is sent to host computer, carry out record, if noted abnormalities, can provide information.When (gas leakage) alarm being connected with alarm interface sends alerting signal, CPU can pass through valve control module valve-off, also can at once this situation be sent to host computer simultaneously, records and provide information.Host computer can be located in residential property duty room or gas company's duty room, need to have people 24 hours on duty.
