Description
Technical field
The utility model relates to a kind of remote meter reading device, relates in particular to a kind of power line communication technology that utilizes and carries out the system that nobody checks meter.
Background technology
The normal operation of intelligent grid needs the support of electric energy information data, so it is extremely important accurately to gather the electricity consumption data.The method of gathering the electricity consumption data generally adopts the variable that is read user's watt-hour meter by data acquisition unit at present, gathers to data concentrator by power line transmission, transmits to Utilities Electric Co.'s control data corporation at last.This method also is the power line carrier remote automatic meter reading system.As shown in Figure 1.
But for general resident, what China adopted is that 220V exchanges two-wire power supply.Because the continuous access of load on the electrical network, cut out, various random occurrences such as the stopping of motor, startup, electric switch operation, thereby the characteristic that makes channel show has very strong time variation.Low-voltage power line can reach 20dB to the attenuation change of a certain frequency signal in 1s, therefore can not utilize simple voltage detection method to determine line signal.Simultaneously, the variation of signal to noise ratio (S/N ratio) also can reach about 10dB in 1s.Secondly, all in parallel many loads on the general low-voltage power line, these loads are very big to the signal attenuation influence; Especially those are used to adjust the big electric capacity of power factor of electric network, concerning the carrier communication signal of hundreds of kHz, are equivalent to short circuit.When load was very little, the internal resistance that sends coupled circuit also can divide the power of quite a few.Once more, line of electric force itself also causes high the reduction to carrier signal.When load on the line of electric force was very heavy, line impedance can reach below 1 ohm, causes the height of carrier signal is cut down.In the practical application, when line of electric force was unloaded, point-to-point carrier signal can be transferred to several kilometers.But when load on the line of electric force is very heavy, can only transmit tens meters.At last, the open and close of various household electrical appliance, the particularly switch and the use of equipment such as the electricity-saving lamp of convertible frequency air-conditioner, adjustable brightness, suction cleaner, usually inject bigger undesired signal to supply line, when causing in the supply line signal transmission, signal to noise ratio (S/N ratio) is extremely low, signal is difficult to factors such as extraction, influenced the one-time success rate of power line carrier communication, thereby cause the existing rate of copying low, can not monitor the duty of each user's watt-hour meter in real time, can not the real-time analysis electric energy data, understand electric network state in real time.
Therefore how to solve the noise that is subjected to owing to line of electric force in the existing meter copying device, thereby the data acquisition unit that causes being positioned at the place, edge being copied the low technical matters of rate, is the problem of the utility model research.
Summary of the invention
The utility model provides a kind of remote meter reading device, its objective is the rate of copying that improves the data acquisition unit that is positioned at the place, edge.
For achieving the above object, the technical solution adopted in the utility model is: a kind of remote meter reading device comprises:
Several user's watt-hour meter are positioned at user side, are used to measure user's power consumption and export variable;

Data concentrator, between control data corporation and data acquisition unit, this data concentrator connects by line of electric force and is connected with data acquisition unit, data concentrator is used to receive the electric quantity acquisition order from control data corporation, and the variable that receives simultaneously from described data acquisition unit also is transmitted to control data corporation with this variable;
The route repeater of configuration route relaying algorithm between described data acquisition unit and data concentrator, is used for transmitting electric quantity acquisition order and variable according to the instruction of data concentrator.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described route repeater specifically comprises: be used to receive order receiving element from the instruction of described data concentrator, be used to receive and transmit data transmit-receive unit from the variable of described data acquisition unit, be used to choose the Route Selection unit of the transmission path of data acquisition unit.
2, in the such scheme, described data concentrator is connected by optical fiber or wireless network with control data corporation.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
The route repeater that increases configuration route relaying algorithm in the utility model in system has solved the data acquisition unit that is positioned at border land point in the existing system and has copied the low problem of rate, this route repeater is installed in appropriate place, and built-in high usage route relaying algorithm, it is smaller to the scope between the target collector, the path is simple relatively, and the effect of checking meter after installing can reach 100%.
