An automatic coding method for a range hood of a central flue system

Abstract

The invention discloses an automatic coding method of a range hood of a central flue system. The automatic coding method comprises the following steps: (1) starting a system; (2) opening a valve plateof an ith electric check valve, and closing all the rest of valve plates; (3) restarting an outdoor unit, and uniformly increasing the rotating speed and ensuring the same increasing speed; (4) recording opening time Ti of the ith valve plate; (5) determining whether the maximum rotating speed of the outdoor unit is reached or not; (6) if yes, determining the fault; (7) if not, determining whether i is equal to N; (8) if i is equal to N, completing opening time recording of all the valve plates under the lowest start-up floor i; (9) if i is less than N, i is equal to i plus one, and returningto the step 2; and (10) following the step 8, regarding the valve plate opening time from long to short as floors from low to high, and performing matching and binding of the floors and MAC address codes on the valve plates. According to an automatic coding mode, by means of the method for controlling the opening and closing of the check valves of all floors through the rotating speed of the outdoor unit, binding of the floors and the address codes can be automatically matched, time and labor are saved, efficiency is improved, and reliability is higher.

Description

technical field [0001] The invention relates to a central flue system, in particular to an automatic coding method for a range hood of the central flue system. Background technique [0002] At present, the floors of newly-built buildings in cities are generally higher and higher. Since the outlets of high-rise public flues are generally set on the top of the floors, the switching status of the range hoods of each user's home will affect the resistance of the system outlet, making the smoke exhaust situation of users at the bottom poor. . In recent years, the user-side adjustable angle valve combined with the centralized filtration and discharge of the main fan at the flue outlet on the roof has begun to be used in some well-decorated buildings. The main fan on the roof, that is, the central range hood, performs frequency conversion + valve preset for users with different operating rates. The angle realizes flow distribution, which can solve the bad smoke exhaust situation o...

[0002] At present, the floors of newly-built buildings in cities are generally higher and higher. Since the outlets of high-rise public flues are generally set on the top of the floors, the switching status of the range hoods of each user's home will affect the resistance of the system outlet, making the smoke exhaust situation of users at the bottom poor.

In recent years, the user-side adjustable angle valve combined with the centralized filtration and discharge of the main fan at the flue outlet on the roof has begun to be used in some well-decorated buildings. The main fan on the roof, that is, the central range hood, performs frequency conversion + valve preset for users with different operating rates. Flow distribution can be achieved at an angle, which can solve the bad smoke exhaust situation of users at the bottom to a certain extent, and at the same time effectively control the flow rate and noise of the entire flue system; Manually collecting the address codes of range hoods on each floor not only consumes a lot of manpower and material resources, but is inefficient, and is prone to errors in the manual collection process, and the reliability is revealed. In the case of replacement or replacement of different floors, or the user replaces the electric valve, the address code needs to be collected manually, which is time-consuming and laborious
