Embodiment 1

[0025] like figure 1As shown, a photovoltaic rolling glass annealing fan communication control system includes a DCS control system (Distributed Control System, distributed control system), and the DCS control system includes a human-computer interaction module, a communication control algorithm module, and I / O signal acquisition Module, touch screen, I / O drive display module, command input device, DP ring network and several annealing fans, the command input device is one of keyboard, mouse or display screen. The DP ring network includes several DP modules, each DP module is connected to a frequency conversion controller control module, each frequency conversion controller control module is connected to an annealing fan, all frequency conversion controller control modules are connected in sequence, and several DP The modules are all connected to the communication control algorithm module, and the communication control algorithm module is connected to the human-computer intera...

Embodiment 2

[0030] The difference between Embodiment 2 of the present invention and Embodiment 1 is that each of the annealing fans is set at intervals, and when an annealing fan fails, the fault information is sent to the DCS system through the frequency conversion controller control module and the DP module connected to it. The main control module, after receiving the fault information, the main control module sends a conversion command to the adjacent annealing fan of the annealing fan, and after receiving the conversion command, the adjacent annealing fan of the annealing fan Deviate from the preset angle. Wherein, the preset angle is determined according to the model of the annealing fan used on site, and the deflection angle of the wind direction of the annealing fan is set within the angle range within which the wind direction of the annealing fan can deflect and stored in the main control module.

[0031] Through the above technical solutions, the communication control system for ...

Embodiment 3

[0033] The difference between embodiment 3 of the present invention and embodiment 2 is: as figure 2 As shown, two wind deflectors 100 are provided at the air outlet of each annealing fan (not shown), and the left and right edges of the air outlet are respectively connected to movable baffles 300 through rotating pivots 200 . The two opposite movable baffles 300, the bottom plate and the top plate encircle a rectangular air outlet; two air deflectors 100 are arranged in parallel with the movable baffle 300 in the air outlet, and each of the air deflectors 100 passes through a steering gear 400 and A movable baffle 300 is connected, and the steering gear 400 simultaneously controls the deflection angle of the connected movable baffle 300 and the wind deflector 100 which are parallel to each other. The movable baffle 300 and the wind deflector 100 divide the air outlet into three ventilation openings , the steering gear 400 is all connected to the main control module, when an a...

Abstract

The invention discloses a photovoltaic calendaring glass annealing fan communication control system and a control method thereof, The control system comprises a DCS control system, wherein the DCS control system comprises a man-machine interaction module, a communication control algorithm module, a DP ring network and a plurality of annealing fans; the DP ring network comprises a plurality of DP modules; each DP module is connected with a frequency conversion controller control module; each frequency conversion controller control module is connected with one annealing fan; all the frequency conversion controller control modules are connected in sequence; the plurality of the DP modules are all connected with the communication control algorithm module; and the communication control algorithm module is connected with the man-machine interaction module. The control system has the advantages that the whole system does not need to lay a large number of cables, the collection information isrelatively more, and control on wind is relatively accurate.

Description

technical field [0001] The invention relates to the field of glass production, and more specifically relates to a communication control system and a control method for a photovoltaic rolling glass annealing fan. Background technique [0002] Rolled glass is a general term for flat glass produced by rolling, including patterned glass, corrugated glass, wired glass, polished glass blanks, and channel glass. Rolled glass is in contact with rolled silver or die-casting tables during the forming process, so the surface is not smooth, which diffuses light, transmits light and is not completely transparent. An important process of rolling glass is glass annealing. The thermal equipment used for glass annealing is called an annealing furnace. Lehrs can be classified according to the movement of the product, heat source and heating method. According to the movement of products, annealing kilns can be divided into three types: intermittent, semi-continuous and continuous; according...
