Abstract

The utility model discloses a lighting switch controlled by a power line carrier. The connection of the lighting switch is that a CPU control unit, a power line carrier unit, a relay output unit, and a lighting monitoring unit are connected via a connecting unit. The lighting switch overcomes defects of high cost, a large size, great operative difficulty, and human body health influence of conventional intellectualized reconstruction of a lamp, does not make high communication demands on an original lighting lamp, and does not need to lay an extra dedicate line. In addition, a wireless manner is replaced by a wired manner so that influence of wireless and radiofrequency signals on human body health is eliminated. Further, such device with a small size can be directly installed in an 86 switch case so as to decrease reconstruction cost and difficulty and to facilitate equipment maintenance. The lighting switch greatly shortens the time of intellectualized reconstruction of the lamp and has strong practicality.

Description

A kind of lighting switch of controlling by power line carrier

Technical field

A kind of lighting switch of controlling by power line carrier of the utility model, current collection line of force carrier communication, MODBUS slave station, relay output, illumination monitoring are integrated, and realize the Long-distance Control of lighting in family and hotel.Belong to the Smart Home field.

Background technology

It is a direction of future development that the intellectuality of lighting is controlled with networking, if directly on lighting, carry out intellectualized reconstruction, need lighting itself to there is communication function, can not realize in a short time, and existing household light fixtures need to be eliminated, the cost of transformation is too high like this, by the general user, is not accepted; Therefore, by controlling the power supply of lighting, control the break-make of power supply and when break-make is a fast and low scheme of cost; Current this scheme has two kinds of implementations, the first is controlled the wall lighting switch with special-purpose communication line, such situation is applicable to the newly-decorated situation of house, and communication line is generally reserved in the room of having fitted up, and the cost that carries out transformation and upgrade is larger; It two is to utilize wireless signal, as radio frequency or ZIGBEE carry out controlled in wireless, although can be transformed the control of existing lighting like this, but the impact of wireless signal on health, can't ignore, and wireless transmission needs external antenna to receive and transmitted signal, and equipment volume is large, affect indoor attractive in appearance; This just has higher requirement to intelligent control of lighting.

Summary of the invention

In existing lighting intellectualized reconstruction, cost is high, volume is large, operation easier is large in order to overcome for the utility model, affect the defects such as health, design a kind of current collection line of force carrier communication, MODBUS slave station, illumination monitoring, relay output of one, realize the wall lighting switch of the Long-distance Control of illumination photometry, lighting in family and hotel.Its technology is achieved in that and comprises power subsystem, the CPU control unit, the power line carrier unit, the relay output unit, the illumination monitoring means, linkage unit, it is characterized in that: its connection is the CPU control unit, the power line carrier unit, the relay output unit, the illumination monitoring means is connected by linkage unit, CPU control unit and power line carrier unit communicate by the serial ports of CPU control unit inside, CPU control unit and relay output unit communicate by the output driving part of linkage unit, CPU control unit and illumination monitoring means communicate by the universal serial bus of linkage unit, power subsystem provides other unit required working power, 8 single-chip microcomputers of the low power consumption and low cost that described CPU control unit has adopted the electric line carrier communication function integrated, described CPU control unit has adopted 8 toggle switchs, can the setting device address, thereby having adopted pulse to control break-make, described relay output unit can save the power magnetic force keeping relay of power consumption, described power subsystem has adopted Switching Power Supply.

Advantage and the effect implemented after this technology are: overcome that lighting intellectualized reconstruction cost was high in the past, volume is large, operation easier is large, affect the defects such as health, original lighting is not proposed to higher communication need, do not need to lay in addition special circuit yet, wireless with wired replacement, eliminated the impact on health of wireless and radiofrequency signal, the device of this small size can be directly installed in 86 switch enclosures, has reduced improvement cost and difficulty, also is easy to the maintenance of equipment; Having shortened greatly the intelligentized improvement project time of lighting, is the lighting Intellectualized controller that a kind of practicality is very strong.

The accompanying drawing explanation

Fig. 1 is the utility model general structure schematic diagram;

Wherein, 1-power subsystem, 2-CPU control unit, 3-power line carrier unit, 4-relay output unit, 5-illumination monitoring means, 6-linkage unit.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further illustrated:

See accompanying drawing 1, connection of the present utility model is to adopt power subsystem 1 with CPU control unit 2, power line carrier unit 3, relay output unit 4, illumination monitoring means 5, be connected by linkage unit 6.Power subsystem 1 is followed other unit to connect and its working power is provided; CPU control unit 2 has adopted 8 single-chip microcomputers of integrated power line carrier communication function; Power subsystem 1 has adopted Switching Power Supply; Relay output unit 4 has adopted high-power twin coil magnetic latching relay; Illumination monitoring means 5 has adopted the high accuracy optical sensor.

Its data are processed and the function implementation procedure is:

(1) software of CPU control unit 1 is based on the realization of C language, do not use embedded OS, reasonable arrangement by interrupt service subroutine, accelerated information processing rate, mainly complete the control of data receiver that the MODBUS main website issues and response, relay output break-make, carry out the address of setting device by the position of toggle switch; CPU control unit 1 is the control core of whole device, and built-in power line carrier data processing function has FLASH, RAM memory, the GPIO interface of enough capacity, possesses enough data-handling capacities and control ability; Integrated level is high, also effectively raises the interference free performance of device;

(2) power subsystem 2 input AC 220V civil powers, scope can change between 85V--265V, output can supply CPU control unit 1, relay output unit 4 and the required 5V DC power supply of illumination monitoring means 5 work, can be for the 16V DC power supply of power line carrier wave unit 3 work;

(3) when data send, the carrier signal that power line carrier unit 3 spreads out of CPU control unit 1 by the two-stage push-pull circuit is amplified, and by isolating transformer, carrier wave is added on civil power; While receiving data, power line carrier unit 3 receives the signal loaded on civil power by isolating transformer, deliver to afterwards after filtering CPU control unit 1;

(4) relay output unit 4 receives the instruction of CPU control unit 1, controls the break-make of output switch power source; The high-power twin coil magnetic latching relay that it is 5V that relay output unit 4 has adopted rated voltage, contact capacity 20A, the pulse wide by 50ms of this relay can realize the break-make control of relay, greatly saved the work energy consumption;

(5) illumination monitoring means 5 has adopted high accuracy illumination photometry transducer, can accurately measure actual illumination, for the CPU element inquiry.
