Description
Technical field
The utility model belongs to signals collecting field, relates to a kind of signal pickup assembly, specifically the online channel signal collecting transmitter of a kind of converting equipment.
Background technology
This year, the safe and stable operation of electric system is one of important leverage of national economy high speed development, and substation equipment in running increasing device data transfer to when data terminal is analyzed and need to be applied to Radio Transmission Technology, the temperature information such as detected in real time the equipment of transforming plant primary outdoor and condensation information all need to be wirelessly transmitted to data terminal and carry out analyzing and processing, therefore need to use a kind of device that the data wireless of collection can be sent to data terminal to carry out data transmission.
Although each data collector of the prior art wirelessly can flow to data terminal respectively, but each data collector is a corresponding wireless data transfer device respectively, and can not be general, therefore each data collector all needs outfit wireless data transfer device, greatly add the maintenance cost of electric system, there is the interface disunity of various equipment, cable access data terminal difficulty, the defect that the failure rate of equipment is high simultaneously.
Utility model content
For solving in prior art the above deficiency existed, the utility model provides the online channel signal collecting transmitter of a kind of converting equipment, can with transformer station in need far-end to transmit the transmission of carrying out signaling channel of all devices support the use.
For achieving the above object, the technical scheme that adopts of the utility model is as follows:
The online channel signal collecting transmitter of a kind of converting equipment, it comprises:
Wireless transmitting terminals, the data receiver of described wireless transmitting terminals connects the signal output part of external data collecting device by antenna, its signal output part is connected with the serial ports of data terminal by level switch module.
As to restriction of the present utility model: described wireless transmitting terminals is micropower wireless radio-frequency communication module NRF401.
Limit as to another kind of the present utility model: described level switch module is MAX232.
Owing to have employed technique scheme, compared with prior art, acquired technical progress is the utility model:
The utility model can receive various collection signal by wireless transmitting terminals and send data terminal to, namely can send all image data to data terminal, makes various equipment interface unified, saves the maintenance cost of electric system.
The utility model is applicable to the data transmission of any power system transformer substation.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is further described in detail.
Fig. 1 is the theory diagram of the utility model embodiment;
Fig. 2 is the circuit theory diagrams of the utility model embodiment.
Embodiment
the online channel signal collecting transmitter of embodiment converting equipment
Present embodiments provide the online channel signal collecting transmitter of a kind of converting equipment, as shown in Figure 1 and Figure 2, comprise: wireless transmitting terminals, the data receiver of described wireless transmitting terminals connects the signal output part of external data collecting device by antenna, its signal output part is connected with the serial ports of data terminal by level switch module.Wireless transmitting terminals in the present embodiment adopts micropower wireless radio-frequency communication module NRF401 of the prior art, and level switch module adopts MAX232 module of the prior art, wherein the communication radius of micropower wireless radio-frequency communication module NRF401 is within 25 meters, therefore the present embodiment is mainly in transformer station's machine room and does not communicate, and then tediously long telecommunication cable can be saved, be conducive to the reduction of the clean and tidy of machine room and maintenance cost; The voltage that data terminal serial ports exports then can be carried out level conversion by MAX232 module, convert the voltage that can be applicable to micropower wireless radio-frequency communication module NRF401 and work to, be micropower wireless radio-frequency communication module NRF401 and electric energy is provided, the Various types of data information that micropower wireless radio-frequency communication module NRF401 receives simultaneously sends data terminal to by the serial ports of MAC232 module, data terminal successively, and micropower wireless radio-frequency communication module NRF401 draws electric energy by the serial ports of MAX232 module, data terminal from data terminal simultaneously.
The physical circuit of the present embodiment is formed as shown in Figure 2, and described micropower wireless radio-frequency communication module NRF401 comprises AT89C2015 single-chip microcomputer U1 and NRF401, and above-mentioned power supply VCC is then drawn by the computer of data terminal by serial ports DB9 by MAX232 module.
