Abstract
An automatic matching method for the address code of a range hood of a central flue system comprises the following steps: firstly, starting a system; secondly, the rotating speed of the outdoor unit is uniformly increased and the rotating speed is the same; thirdly, judging whether the highest rotating speed is reached; fourthly, if yes, judging a fault; if not, recording the opening time T (n) and T (n + i) of the valve plate, and delta Ti ═ T (n + i) -T (n); sixthly, judging whether N is equal to the total floor number N; seventhly, if N is equal to N, the step is shifted to step 0; if N is not equal to N, i is i +1, and comparing delta Ti; ninthly, judging whether i is equal to N-N; c, if i is equal to N-N, completing comparison of opening time of all valve plates and recording all delta T;
if i is less than N-N, returning to the step II;
and D, receiving the third step, sequencing all delta T, taking the opening time of each valve plate from long to short as the floor from low to high, and matching and binding the floor and the MAC address code. This automatic coding mode is through the valve block open time contrast of two liang of different floors, and the automatic matching floor is bound with the address code, has promoted efficiency.
Description
Technical Field
The invention relates to a central flue system, in particular to an automatic matching method for an address code of a range hood of the central flue system.
Background
At present, floors of newly-built floors in cities are generally higher and higher, and the outlet of a high-rise common flue is generally arranged at the top of the floors, so that the outlet resistance of a system can be influenced by the switching condition of a range hood of each user, and the smoke exhaust condition of users at the bottom is severe. In recent years, a user side angle-adjustable valve is combined with a roof flue outlet main fan to intensively filter and discharge, and the valve is applied to certain finish-finished building plates, the roof main fan, namely a central range hood, performs frequency conversion and valve plate preset angle to realize flow distribution aiming at users with different opening rates, the problem of bad smoke discharge of users at the bottom can be solved to a certain extent, and the flow rate and the noise of the whole flue system are effectively controlled; however, the regulating valve in this way needs to be manually bound with the floors in advance, the collection of the address codes mainly adopts a manual collection mode of the address codes of each layer of range hood manually, so that the method not only consumes large manpower and material resources and is low in efficiency, but also is easy to make mistakes in the manual collection process and low in reliability, and if the conditions such as replacement of the range hood or replacement of different floors and the like occur subsequently, or a user changes an electric valve, the address codes need to be manually collected again, and the method is time-consuming and labor-consuming.
Disclosure of Invention
The invention aims to solve the technical problem of providing an automatic matching method for the address code of the range hood of the central flue system, which can automatically match floors and bound with the address code.
The technical scheme adopted by the invention for solving the technical problems is as follows: the automatic matching method for the address code of the range hood of the central flue system comprises indoor units arranged on each floor, wherein the air outlet of each indoor unit is communicated with a common flue through respective smoke pipes, each smoke pipe is provided with an electric check valve, each electric check valve is provided with a valve plate, and the top of the common flue is provided with an outdoor unit, and the automatic matching method is characterized in that: the automatic address code matching method comprises the following steps:
firstly, starting a system;
secondly, restarting the outdoor unit, uniformly increasing the rotating speed and keeping the increasing rate the same;
thirdly, judging whether the highest rotating speed of the outdoor unit is reached;
fourthly, if yes, judging a fault;
if not, recording the opening time T (n) and T (n + i) of the valve plate of the nth and n + i electric check valves, and delta Ti (n + i) -T (n);
sixthly, judging whether N is equal to N, wherein N is the total floor number;
seventhly, if N is equal to N, transfer to step r;
(viii) if N ≠ N, i ═ i +1, and then the opening times T (N) and T (N + i) of N and N + i are compared, and Δ Ti ═ T (N + i) -T (N);
ninthly, judging whether i is equal to N-N;
c, if i is equal to N-N, comparing opening time of all valve plates of the lowest starting floor N and recording delta T0, delta T1 and … … delta T (N-N);
Preferably, the outdoor unit has a booster fan.
The valve plate opening time can be recorded by various devices, and preferably, an electromagnetic switch for recording the valve plate opening time is installed on the smoke pipe.
Compared with the prior art, the invention has the advantages that: this automatic coding mode is through the contrast of two liang of different floor check valve opening times to obtain the sequencing of all floor check valve opening times, automatic matching floor and binding of address code, labour saving and time saving has promoted efficiency, and the reliability is higher, if the follow-up condition such as change that appears range hood or check valve, also can bind floor and address code automatically again, work efficiency improves greatly.

Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
As shown in fig. 1 to 2, the central flue system of the present embodiment includes indoor units 1 installed on each floor, an air outlet of each indoor unit 1 is communicated with a common flue 3 through a respective smoke tube 2, an electric check valve 4 and an electromagnetic switch 6 are installed on the smoke tube 2, the electric check valve 4 has a valve plate 41 capable of being opened and closed, and the electromagnetic switch 6 is used for recording the opening time of the valve plate 41. An outdoor unit 5 is installed on the top of the common flue 3, and the outdoor unit 5 is provided with a booster fan.
As shown in fig. 3, the automatic matching method for the address code of the range hood of the central flue system of the embodiment includes the following steps:
firstly, starting a system;
secondly, restarting the outdoor unit, uniformly increasing the rotating speed and keeping the increasing rate the same;
thirdly, judging whether the highest rotating speed of the outdoor unit is reached;
