Description

The collection system and lamp control system of light fixture operating state data

Technical field

The present invention relates to fixture technical field, more particularly to a kind of collection system of light fixture operating state data and Lamp control system.

Background technology

Light units is the visual plant of stage, and the monitoring and control to light fixture is the most important portion of light units work Point.And the monitoring to light fixture at present is mainly completed by DMX521, the control to light fixture is completed by RDM.DMX512 It is the standard for controlling light units and transmitting digital data, the standard agreement can control 512 light modulators, each light modulator Brightness degree scope is 0-255 levels.The frequency that usual controller sends DMX512 is 40Hz, a frame data (each frame data 512 It is individual to be used to control the byte of light fixture) need about 22mS, midfeather about 3mS.RDM agreements are remote device management (Remote Device Management) agreement, based on DMX512-A, DMX512-A can regard the DMX of data double-way transmission as. Under RDM agreements, control system can send request to light fixture, light fixture also can response these requests, and can be in console The setting of upper change light fixture, every compatible RDM light fixture can be identified by the only identification code built in it.

In existing control framework, DMX512 and RDM are to transmit data using the bus of identical 485, and DMX512 is control Device processed can only be controlled as 485 buses always toward data are sent either with or without problem, light fixture either with or without data or packet loss is received Device processed can not be known;Because 458 buses are half-duplex states when RDM works, i.e.,:RDM controllers send one to light fixture Corresponding order, corresponding light fixture can respond a data to controller, and this mode of operation is equivalent to " intercom " pattern.Cause Need to run DMX512 data and RDM data for 458 buses, and synchronization is merely able to run DMX512 data or RDM data.Pin For above-mentioned half-duplex working condition, according in general solution, i.e., by the way of poll, but other shadows can be brought Ring, because with regard to 3mS or so between each frames of DMX512, either light fixture or control system is all difficult the operation for completing RDM, such as Fruit, which extends this off time, to cause to be delayed to 512 signals.

In summary, the control framework of existing light units, the monitoring and control data transmission efficiency to light fixture is relatively low, It is difficult to ensure that light units working stability works.

The content of the invention

Based on this, it is necessary in view of the above-mentioned problems, providing a kind of receipts of the higher light fixture operating state data of monitoring efficiency Collecting system and the lamp control system higher with control efficiency.

A kind of collection system of light fixture operating state data, including:Control system, data forwarding device and data acquisition Device;

The control system is connected by data forwarding device with data acquisition device, and the data acquisition device passes through One bus is connected with each light fixture respectively;

The data acquisition device timing sends data acquisition instructions by the first bus to light fixture, and each light fixture receives After the data acquisition instructions, corresponding operating state data is fed back to by data acquisition device by the first bus;

The operating state data is forwarded to the data forwarding device by the data acquisition device;

The operating state data of each light fixture is collected to control system by the data forwarding device.

The collection system of above-mentioned light fixture operating state data, new light units control framework is constructed, by independent Data/address bus collects light fixture operating state data, and sending data to light fixture by first bus from data acquisition device timing adopts Collection instruction, is then collected to control system by the corresponding operating state data of each light fixture by data forwarding device.It can carry The efficiency of high light fixture status data collection, it is difficult to ensure that light units working stability works, meet master control and stage director Demand data.

A kind of lamp control system, including:Control system, data forwarding device, data acquisition device and light units Controller;

The control system is connected by data forwarding device with data acquisition device, and the data acquisition device passes through One bus is connected with each light fixture respectively, and light units controller connects each light fixture respectively by the second bus;

The data acquisition device timing sends data acquisition instructions by the first bus to light fixture, and each light fixture receives After the data acquisition instructions, corresponding operating state data is fed back to by data acquisition device by the first bus;

The operating state data is forwarded to the data forwarding device by the data acquisition device;

The operating state data of each light fixture is collected to control system by the data forwarding device;

The light units controller sends control data by the second bus to each light fixture, enters portable lighter to each light fixture Photocontrol.

Above-mentioned lamp control system, construct new light units control framework, light units controller and control system Collect light fixture operating state data by independent the first data/address bus and the second data/address bus respectively and send control data, Data acquisition instructions are sent to light fixture by the first bus from data acquisition device timing, then each light fixture worked accordingly Status data is collected to control system by data forwarding device.The monitoring and control data transfer to light fixture can be significantly improved Efficiency, it is ensured that light units working stability works, and meets master control and the demand data of stage director.
