Abstract
The utility model discloses a communication system for remote meter reading. The communication system comprises a local communication unit in a concentrator and an intelligent meter communication unit in a collector, wherein the local communication unit comprises a communication control module I as well as a carrier transmitting-and-receiving module I and a wireless transmitting-and-receiving module I which are controlled by the communication control module I; the intelligent meter communication unit comprises a communication control module II as well as a carrier transmitting-and-receiving module II and a wireless transmitting-and-receiving module II which are controlled by the communication control module II; the carrier transmitting-and-receiving module I and the carrier transmitting-and-receiving module II are connected through a power line. The communication system for remote meter reading has a power line carrier communication channel and a wireless communication channel, when the power line carrier communication channel is distorted due to interference signals or fails in communication, the communication control modules try wireless communication automatically, and two communication methods are automatically switched and are mutually complementary, so that the problem that current centralized meter reading systems are low in success rate is well solved.
Description
Technical field
The utility model relates to remote meter reading, particularly a kind of communication system for remote meter reading.
Background technology
Traditional centralized meter-reading system adopts power line carrier communication, advantage is again laying-out, utilize existing line of electric force to carry out signal transmission as medium, but system channel is easily subject to the impact of the equipment such as on-the-spot servomotor, large capacity motor, convertible frequency air-conditioner, there is high reduction and high distortion in power line signal transmission.The electromagnetic wave wireless meter-reading system growing up gradually in recent years, utilizes external electromagnetic field transmission electromagnetic wave signal, without considering line conditions, but its between high building, shielding place and have the ambient signal decay of electromagnetic interference (EMI) very large, the system success ratio of checking meter is not high.
Utility model content
For overcoming the shortcomings and deficiencies of above-mentioned prior art, the utility model provides a kind of communication system for remote meter reading time with power line carrier, PLC passage and wireless communication.
The technical solution of the utility model is:
For a communication system for remote meter reading, comprise the intelligent meter communication unit in local communication unit and the collector in concentrator, described local communication unit comprises communication control module one and is subject to carrier transmitting-receiving module one and the radio receiving transmitting module one of its control; Intelligent meter communication unit comprises communication control module two and is subject to carrier transmitting-receiving module two and the radio receiving transmitting module two of its control, and described carrier transmitting-receiving module one is connected by line of electric force with carrier transmitting-receiving module two.
Preferably, described radio receiving transmitting module one and radio receiving transmitting module two are electromagnetic wave transceiver module.
The communication system for remote meter reading described in utility model herein, there is power line carrier, PLC passage and wireless communication simultaneously, there is undesired signal distortion or communicate by letter when unsuccessful at power carrier channel, communication control module is attempted radio communication automatically, two kinds of communication modes automatically switch, learn from other's strong points to offset one's weaknesses, solved well the low problem of current centralized meter-reading system success ratio.
Brief description of the drawings
Fig. 1 is the embodiment schematic diagram of the communication system for remote meter reading described in the utility model.
Embodiment
Understand technology contents of the present utility model for convenience of those skilled in the art, below in conjunction with embodiment, the utility model is described in further detail.
As shown in Figure 1, the communication system for remote meter reading that the utility model discloses, comprise the intelligent meter communication unit in local communication unit and the collector in concentrator, described local communication unit comprises communication control module one and is subject to carrier transmitting-receiving module one and the radio receiving transmitting module one of its control; Intelligent meter communication unit comprises communication control module two and is subject to carrier transmitting-receiving module two and the radio receiving transmitting module two of its control, and described carrier transmitting-receiving module one is connected by line of electric force with carrier transmitting-receiving module two.Described radio receiving transmitting module one and radio receiving transmitting module two are electromagnetic wave transceiver module.
The communication system for remote meter reading described in utility model herein, there is power line carrier, PLC passage and wireless communication simultaneously, there is undesired signal distortion or communicate by letter when unsuccessful at power carrier channel, communication control module is attempted radio communication automatically, two kinds of communication modes automatically switch, learn from other's strong points to offset one's weaknesses, solved well the low problem of current centralized meter-reading system success ratio.
In the utility model, the not concrete functional module of introducing all can adopt ripe functional module of the prior art.
Above-described embodiment is only wherein specific implementation of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these apparent replacement forms all belong to protection domain of the present utility model.
