Abstract
The utility model discloses a carrier wave testing device which comprises an electric energy meter, an attenuator and a copy controller, wherein the electric energy meter is electrically connected with the attenuator which is electrically connected with the copy controller; and the device also comprises an isolator, one end of which is electrically connected with the electric energy meter, and the other end thereof is electrically connected with a 220V power grid. The carrier wave testing device has good communication effect so as to further guarantee the copy reading data to be accurate.
Description
Technical field
The utility model relates to the electric energy meter technical field, specifically is a kind of carrier test device.
Background technology
The carrier test device of prior art comprises electric energy meter, attenuator and copies the control device that wherein, electric energy meter is electrically connected with attenuator, 220V electrical network respectively; Attenuator with copy the control device be electrically connected.Because the non-constant of environment in the electrical network of carrier test device place, exist many undesired signals that is changing, and between electric energy meter in the carrier test device and the 220V electrical network without any the device that stops undesired signal, therefore these signals can directly interfere with the carrier test device, make that the communication effect of carrier test device is relatively poor, and then make the copy reading data of carrier test device occur than mistake.
The utility model content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, provides a kind of communication effect good and then guarantee copy reading data carrier test device accurately.
The technical solution of the utility model is, a kind of carrier test device is provided, and comprises electric energy meter, attenuator and copy the control device that described electric energy meter is electrically connected with attenuator; Described attenuator is electrically connected with copying the control device, and it also comprises isolator, and an end of described isolator is connected with electrical energy meter electricity, and the other end of described isolator is electrically connected with the 220V electrical network.
After adopting above structure, the utility model compared with prior art has the following advantages:
The utility model carrier test device has increased an isolator between electric energy meter and 220V electrical network, influence the communication effect of carrier test device in order to the undesired signal that stops electrical network, make the carrier test device obtain a communication effect preferably, and then guaranteed that the copy reading data of carrier test device are accurate.
Description of drawings
Accompanying drawing is the structured flowchart of the utility model carrier test device.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of carrier test device of the utility model comprises electric energy meter, attenuator and copies the control device that the data output end of described electric energy meter is connected by lead with the data input pin of attenuator; The data output end of described attenuator is electrically connected with the data input pin of copying the control device, and it also comprises isolator, and an end of described isolator is connected by lead with electric energy meter, and the other end of described isolator is connected by lead with the 220V electrical network.Described isolator is the commercially available prod, as the isolator of the scientific and technological TH41 model of China.
Principle of work: after the normal operation of carrier test device, be filtered when undesired signal is through isolator on the 220V electrical network, thereby make the carrier test device obtain a pure working power, avoided the communication in the table to receive interference.When needs copy reading data, be delivered to electric energy meter by the order of will making a copy for of host computer or palm PC through copying control device, attenuator, then by electric energy meter will make a copy for data through attenuator, copy the control device, be delivered to host computer or palm PC.
