Detailed Description
In order that the above-recited objects, features and advantages of the present invention will be more readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
Example 1
As shown in fig. 4, the embodiment provides a method for controlling the air volume of a central flue system, which includes the following steps:
s1, acquiring a current air quantity threshold A transmitted to a floor by an indoor smoke machine of each floor, wherein the current air quantity threshold A is transmitted among floors layer by layer;
s2, when the rotating speed of a fan of the indoor smoke machine reaches the maximum, the actual air quantity Q of the indoor smoke machine is still smaller than the current air quantity threshold A;
judging whether the current air volume threshold A is the air volume threshold A in the last communication process or not;
if yes, the indoor smoke machine sends a smaller air volume threshold A to the communication network so as to update the current air volume threshold A in the communication network; if not, returning to S1.
In the embodiment, the indoor smoke machine of each floor acquires a current air volume threshold A transmitted to the floor, wherein the current air volume threshold A is transmitted among the floors layer by layer; when the rotating speed of the fan of the indoor smoke machine reaches the maximum, the actual air quantity Q of the indoor smoke machine is still smaller than the current air quantity threshold A, and the fact that the actual air quantity is smaller than the current air quantity threshold A can not be achieved only by adjusting the rotating speed of the fan of the indoor smoke machine at the moment is indicated, so that the current air quantity threshold A needs to be reduced at the moment; however, considering that each indoor smoke machine on each floor needs an adaptation process when the air volume threshold A is reduced, judging whether the current air volume threshold A is the air volume threshold A in the last communication process or not; if yes, the indoor smoke machine sends a smaller air volume threshold A to the communication network so as to update the current air volume threshold A in the communication network; if not, returning to the S1, so that the problem of uneven air quantity matching of indoor smoke machines of all floors in the conventional central flue system is solved.
In addition, "judging whether the current air volume threshold A is the air volume threshold A in the last communication process", namely judging whether the current air volume threshold A is changed compared with the air volume threshold A in the last communication process, if so, not adjusting the current air volume threshold in the last communication process; if the air quantity threshold value changes, the current air quantity threshold value in the communication process is adjusted, so that the air quantity threshold value only changes once in the transmission process of the primary air quantity threshold value A, and the purpose is to give the indoor smoke machine a reaction time. If the air quantity threshold value is adjusted at a high frequency, the running indoor smoke machine is likely to be in short of reaction, and the air quantity cannot be accurately adjusted.
Further, the current air volume threshold a is transferred layer by layer between floors, and specifically includes:
the current air volume threshold A is sequentially transferred from a high floor to a low floor layer by layer in a fixed period.
Further, the current air volume threshold a is transferred layer by layer between floors, and specifically includes:
the current air volume threshold A is sequentially transferred from a low floor to a high floor layer by layer in a fixed period.
The following describes the transmission process of the current air volume threshold value A by taking the transmission of the current air volume threshold value A from a high floor to a low floor in a fixed period orderly layer by layer as an example.
The air volume threshold value A is transferred orderly and stepwise in a fixed period, preferably from a high floor to a low floor (or from the low floor to the high floor or disordered), and after the air volume threshold value A is transferred once, the air volume threshold value A is transferred reversely by a terminal floor, so that each floor receives an air volume threshold value signal and informs that the starting floor is transferred completely, as shown in fig. 3, after a period of time, the next transfer process is carried out.
For example: the current air volume threshold A is firstly transferred from a high floor N to an N-1 layer, then transferred to a low floor layer by layer until being transferred to a first layer, so that the air volume threshold A completes one-time signal transfer; then, if the indoor smoke machine of the first layer sends a smaller air volume threshold value A to the communication network as the current air volume threshold value A, the first layer transmits the current air volume threshold value A to the second layer, and then transmits the current air volume threshold value A to the high floors layer by layer, so that the indoor smoke machine of each floor can receive the updated air volume threshold value A.
Further, the method comprises the following steps, as shown in fig. 5:
judging whether the indoor smoke machine is turned off from the running state to the off state;
if not, the indoor smoke machine of each floor acquires the current air quantity threshold A transmitted to the floor;
if yes, the indoor smoke machine which is shut down sends a default air volume threshold A' to a communication network so as to update the current air volume threshold A; the indoor smoke machine of each floor acquires the current air quantity threshold A transmitted to the floor.
In a specific embodiment, if the indoor smoke machine is turned off, the resistance in the public flue is necessarily changed, so that the air quantity adjustment state needs to be re-entered at this time, that is, the turned-off indoor smoke machine sends a default air quantity threshold value A ' to the communication network to update the current air quantity threshold value A, then the default air quantity threshold value A ' is transmitted among floors layer by layer, and after other running indoor smoke machines acquire the default air quantity threshold value A ', the air quantity state is re-adjusted.
Further, before determining whether the current air volume threshold a is the air volume threshold a in the last communication process, the method specifically includes the following steps, as shown in fig. 6:
judging whether the actual air quantity Q of the indoor smoke machine is equal to the current air quantity threshold A or not;
if the current air quantity threshold value A is equal to the current air quantity threshold value A, the indoor smoke machine continuously acquires the current air quantity threshold value A transmitted to the floor;
if the air quantity Q is larger than the current air quantity threshold A, the indoor smoke machine reduces the rotating speed of the fan, and judges whether the actual air quantity Q of the indoor smoke machine is equal to the current air quantity threshold A;
if the rotational speed of the fan of the indoor smoke machine is less than the rotational speed of the fan of the indoor smoke machine is judged to be the maximum; if not, the indoor smoke machine increases the rotating speed of the fan, and judges whether the actual air quantity Q of the indoor smoke machine is equal to the current air quantity threshold A or not; if so, judging whether the current air volume threshold A is the air volume threshold A in the last communication process.
In the specific embodiment, the indoor smoke machine firstly adjusts the rotating speed of a fan to enable the actual air quantity Q to approach the current air quantity threshold A as much as possible; if the fan rotation speed reaches the maximum, the actual air quantity Q is still smaller than the current air quantity threshold A, and the purpose that the actual air quantity Q is equal to the current air quantity threshold A cannot be achieved by adjusting the fan rotation speed is achieved, so that the indoor smoke machine needs to send a smaller air quantity threshold A to the communication network at the moment so as to update the current air quantity threshold A in the communication network. However, considering that the air quantity is transferred layer by layer in the transfer process of the air quantity A, in order to enable the indoor smoke machines on other floors to fully reflect the changed air quantity threshold A, the air quantity threshold A is only reduced once in the layer by layer transfer process, namely, before the air quantity threshold A is reduced, whether the current air quantity threshold A is the air quantity threshold A in the last communication process is judged first, if so, the indoor smoke machines send smaller air quantity threshold A into a communication network so as to update the current air quantity threshold A in the communication network; if not, the indoor smoke machine continues to acquire the current air quantity threshold A transmitted to the floor.
The following describes the air volume adjusting process of the present embodiment by taking 7 floors as an example:
the current transmission process of the air quantity threshold A is as follows: 7- > 6- > 5- > 4- > 3- > 2- > 1, 1- > 2- > 3- > 4- > 5- > 6- > 7;
assuming that the number of the starting-up units is 1, 3, 5 and 6 layers, and the current air quantity threshold A is 8m 3 /min, default threshold of 14m 3 And/min. The revolution of each starting user is 1400rpm, 1200rpm, 1000rpm and 800rpm respectively, and the actual exhaust air quantity is 8m 3 And/min, at this time, uniform exhaust of each floor is realized.
At this time, if the indoor unit of the 6 layers is turned off, the indoor unit of the 6 layers sends a default air volume threshold a' to the communication network so as to update the current air volume threshold a.
At this time, the current air volume threshold A is firstly transferred to the indoor smoke machines of 5 layers, then the indoor smoke machines of 3 layers and finally the indoor smoke machines of 1 layer along with a signal transfer process (n), so that the air volume threshold is reset for each floor. At this time, the revolution numbers of the layers 1, 3 and 5 were increased to 1400rpm (maximum revolution number), and the actual air volume Q was 9m 3 /min、11m 3 /min、13m 3 /min。
After the reset is completed, the next transfer process (n+1) is entered.
In the (n+1) transmission process, the first starting floor is 5 floors, and after the air quantity judgment, when the revolution is maximum, the air quantity can not meet the current threshold value of 14m 3 The criterion of/min is then a threshold value of 13m is lowered 3 /min (14-1). With the signaling process (n+1), the threshold of each layer becomes 13m 3 And/min. 1. The revolution of the 3 and 5 layers is still 1400rpm (maximum revolution), and the actual air quantity is 9m 3 /min、11m 3 /min、13m 3 And/min. For ease of illustration, the following dispensing process is illustrated by table 1.
Table 1 changes in actual air volume at each floor as the number of times of transfer of the current air volume threshold a at each floor increases
From table 1, after the n+4 times of air volume threshold value a is transferred, the air volume distribution of each floor of the central flue system is completed, and the actual air volume Q of each floor is equal to the current air volume threshold value a, so that the problem that the indoor smoke machines of each floor are unevenly matched in the conventional central flue system is effectively solved.
