Embodiment 1

[0025] like figure 1As shown, a photovoltaic rolled 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 the 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 in...

Embodiment 2

[0030] The difference between the second embodiment of the present invention and the first embodiment is that each of the annealing fans is set at intervals, and when one 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 the adjacent annealing fan of the annealing fan receives the conversion command, it adjusts the wind direction and sends the faulty annealing fan to the annealing fan. Deviate from the preset angle. Among them, the preset angle is determined according to the model of the annealing fan used on site, and the wind direction deflection angle of the annealing fan is set within the angle range that the wind direction of the annealing fan can deflect and is stored in the main control...

Embodiment 3

[0033] The difference between Embodiment 3 of the present invention and Embodiment 2 is: figure 2 As shown, two air guide plates 100 are arranged at the air outlet of each of the annealing fans (not shown), and the left and right edges of the air outlet are connected to the movable baffle 300 through pivots 200 respectively. The two opposite movable baffles 300, the bottom plate and the top plate form a rectangular air outlet; two wind deflectors 100 are arranged in parallel with the movable baffle 300 in the air outlet, and each air deflector 100 is connected to the air outlet through a steering gear 400. A movable baffle 300 is connected, and the steering gear 400 simultaneously controls the deflection angle of the parallel movable baffle 300 and the wind deflector 100 connected to it. The movable baffle 300 and the wind deflector 100 divide the air outlet into three vents. , the steering gear 400 is connected with the main control module, when an annealing fan fails, the f...

Abstract

The invention discloses a communication control system and a control method for a photovoltaic rolled glass annealing fan. The control system includes a DCS control system, and the DCS control system includes a human-computer interaction module, a communication control algorithm module, a DP ring network and several annealing fans. 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 the frequency conversion controller control modules are connected in sequence, and several DP modules are connected. Both are connected to the communication control algorithm module, and the communication control algorithm module is connected to the human-computer interaction module; the advantages of the present invention are: the whole system does not need to lay a large number of cables, collects more information and controls the wind more accurately.

Description

technical field [0001] The invention relates to the field of glass production, in particular to a communication control system and a control method of a photovoltaic rolled glass annealing fan. Background technique [0002] The general term for flat glass produced by the calendering method when rolling glass, including patterned glass, corrugated glass, wired glass, polished glass blank, and channel glass. During the forming process of the rolled glass, it is in contact with the rolled silver or the die-casting table, so the surface is not smooth, so that the light is diffused, light is transmitted and not completely transparent. An important process of rolling glass is glass annealing. The thermal equipment used for glass annealing is called annealing kiln. Annealing kilns can be classified by product movement, heat source and heating method. Annealing kilns can be divided into three types: intermittent type, semi-continuous type and continuous type according to the move...
