Description

Remote control and temperature acquisition system based on power-line carrier communication

Technical field

The utility model is related to a kind of signal transmission and collection product, belongs to communication and automation field.

Background technology

Power line carrier communication is distinctive power system, and basic communication mode has information transfer reliable and stable using power line as the transmission medium of carrier signal, and route is reasonable, can concurrent multiplexing signal the features such as.

Power line and holding wire are unified, and without laying holding wire, as long as being internally equipped with power line carrier communication chip, more new procedures just can realize the transformation to original household electrical appliances Control on Communication mode. Therefore, power-line carrier communication has extensive prospect in data acquisition, electrical control, home intelligence application aspect in the future, particularly has reliability across height in middle lower rate transmissions application aspect, the features such as cheap.

The content of the invention

In order to overcome the shortcoming of power line and holding wire repetition arrangement in electricity system, the utility model is unified using power line and holding wire, without the design for laying holding wire, solves disadvantages mentioned above.

The utility model solves the technical scheme that its technical problem used: host computer can be with multiple slave computer composition control real-time performances to the temperature acquisitions and digital output modul of the multiple points in a transformer region. Because power line carrier, PLC is half-duplex operation, and host computer will communicate with multiple slave computers so we are in advance to the unique address code of each slave computer one, then row data communication and control are entered by the way of poll, the packet that host computer sends contains one group of lead code, one group address code, one group of controlling instruction code. All of slave computer can receive the data of host computer, and then slave computer compares address code with oneself unique address code, responded if equal and acted accordingly, otherwise without response. Constantly refreshing shows the temperature value that host computer will be collected. System is the one-to-many controlling network collectively constituted by PC, upper computer module, keyboard display module, modulation /demodulation module one, modulation /demodulation module two, power module, temperature sensor group, lamp group, power line, slave computer module, realizes temperature acquisition and digital output modul to the multiple points in a transformer region. Power module is connected realization with upper computer module, modulation /demodulation module to these module for power supply; PC is connected with upper computer module and realizes man-machine interaction and send control command to host computer; Upper computer module connection keyboard display module realizes parameter setting and display; Circuit modulation /demodulation module one is connected with upper computer module, power line and realizes the digital signal modulated of host computer to be coupled on power line after analog signal; Modulation /demodulation module two is connected with slave computer module, power line and realizes that the analog signal on power line is demodulated into data signal is sent to slave computer module; Slave computer is connected with lamp group and realizes control to lamp group; Slave computer is connected with temperature sensor and realizes temperature acquisition; Host computer is received slave computer data and is shown by continuous refreshing of temperature value that PC and keyboard display module will be collected.

The beneficial effects of the utility model are that remote control and temperature acquisition system based on power-line carrier communication solve the shortcoming of power line and holding wire repetition arrangement in electricity system.
