Description

Serial-parallel conversion line lamp

Technical Field

The utility model relates to the technical field of lighting fixtures, especially, relate to a line lamp of cluster conversion.

Background

For a line lamp, the traditional lamp transmission adopts SPI series signal transmission, and nowadays, standard DMX512 parallel signal transmission is more adopted.

As shown in fig. 1, if some fault occurs in the middle of the serial SPI signal transmission, all the following lamps cannot work normally.

As shown in fig. 2, the DMX parallel signal lamps have a small number of loads, and only 512 channels can be loaded. The transmission frequency is low, only 250 kbps.

SUMMERY OF THE UTILITY MODEL

The utility model provides a line lamp of cluster parallel conversion, the lamps and lanterns that have solved parallel signal carry a small amount of problem, have solved transmission distance ratio nearer problem simultaneously.

The utility model provides a line lamp of cluster and parallel conversion, including control module, lamp body, control module links to each other with the lamp body and constitutes lamps and lanterns, lamps and lanterns are a plurality of, and a plurality of lamps and lanterns are established ties and are constituteed the line lamp together, control module includes the treater and with the switch that the treater links to each other, the treater can discern the exactness of data output, and during normal work, data input is after the treater handles, and data output is to the treater of next control module; when the processor finds that the data is in error, the processor conducts the external switch to close the switch, so that the data is transmitted to the next processor through the switch.

As a further improvement of the utility model, the processor is an MCU.

As a further improvement of the present invention, the switch is a relay switch.

As a further improvement of the utility model, the lamp body is an LED lamp.

As the utility model discloses a further improvement, MCU has a detection source, detects output signal's high level, when judging that data is not at the high level, MCU affirms data output so and has the mistake, MCU triggers through the IO mouth relay switch makes relay switch is closed to make data warp relay switch transmits to next MCU.

As a further improvement of the utility model, this line lamp still includes power supply circuit, power supply circuit with lamps and lanterns link to each other, power supply circuit is right lamps and lanterns supply power.

As a further improvement, the utility model discloses a this line lamp still includes LED constant current drive circuit, LED constant current drive circuit with the LED lamp links to each other.

The utility model has the advantages that: the utility model discloses it is far away to have integrateed SPI transmission distance, and the many advantage of area load has also integrateed bad one among the DMX512 parallel signal and has not influenced other advantages, through this kind of mechanism, more can reduce the fault rate of product in practical application, also corresponding reduction because of the problem appearance of individual trouble influence large tracts of land.

Detailed Description

As shown in fig. 3, the utility model discloses a line lamp of cluster-parallel conversion, including control module 10, lamp body, control module 10 with the lamp body links to each other and constitutes lamps and lanterns, lamps and lanterns are a plurality of, and a plurality of lamps and lanterns are established ties and are constituteed the line lamp together, control module 10 includes the treater and with the switch that the treater links to each other, the treater can discern the exactness of data output, and during normal work, data input is behind the treater processing, and data output is to the treater of next control module 10; when the processor finds that the data is in error, the processor conducts the external switch to close the switch, so that the data is transmitted to the next processor through the switch.

As shown in fig. 4 and 5, the processor is an MCU11, the switch is a relay switch 12, and the lamp body is an LED lamp.

Under the normal working condition, data are input and processed by the MCU11, and then are output to the next MCU11, and at the moment, the serial working mode is realized.

When the MCU11 finds that data output is in a problem, the MCU11 judges the inside, the MCU11 has a detection source to detect the high level of an output signal, when judging that the data is not at the high level, the MCU11 determines that the data output has errors, the MCU11 triggers the relay switch 12 through an IO port to close the relay switch 12, so that the data is transmitted to the next MCU11 through the relay switch 12, the transmission of the next-stage data is not influenced, and the serial working mode is converted into the parallel working mode at the moment.

As shown in fig. 6, the line lamp further includes a power circuit, the power circuit is connected to the lamp, and the power circuit supplies power to the lamp.

As shown in fig. 7, the line lamp further includes an LED constant current driving circuit, and the LED constant current driving circuit is connected to the LED lamp.

The utility model discloses it is far away to have integrateed SPI transmission distance, and the many advantage of area load has also integrateed bad one among the DMX512 parallel signal and has not influenced other advantages, through this kind of mechanism, more can reduce the fault rate of product in practical application, also corresponding reduction because of the problem appearance of individual trouble influence large tracts of land.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
