Description

Technical Field

[0001] The present invention relates to the technical field of fireproof rolling shutters, and in particular to a fireproof rolling shutter zoning control method based on wireless control. Background Art

[0002] With the country's large-scale infrastructure construction (such as subways, airport and stadium renovations), the demand for rolling shutter doors in buildings is increasing, and the performance requirements are becoming increasingly higher. In these important places, the fire alarm level requirements are becoming increasingly higher. Currently, densely populated shopping malls, underground rail transit, underground parking lots, and factories mostly use fire shutters to open or close for fire control.

[0003] However, the motor of a typical fire shutter and the controller that controls the motor are generally located high above the door body, making it very cumbersome to control the opening and closing of the fire shutter. Furthermore, each fire shutter can be opened and closed individually during use, often requiring only one fire shutter controller to be debugged individually. For example, Chinese patent CN105182963A discloses a test device for a fire shutter door controller, comprising a test device body, an analog control unit mounted on the test device body, and a panel. The analog control unit includes an analog power supply and control unit, an analog load unit, an electrical parameter test unit, a simulated smoke and temperature unit, a simulated full-derating and half-derating unit, and an operation feedback unit, each connected to the fire shutter door controller. The analog control unit also includes a switching power supply unit that provides a DC voltage to the analog power supply and control unit and the operation feedback unit. The test device for a fire shutter door controller provided by the above invention not only improves work efficiency but also addresses potential safety hazards for personnel. Furthermore, the functions of the fire shutter door controller can be comprehensively tested, which not only saves costs but also improves production efficiency. There is an urgent need for the development of a method for debugging fire shutters in batches.

[0004] In addition, the requirements for remote control of fire shutters are getting higher and higher, so many fire shutters are equipped with remote control button boxes. The remote control methods are divided into wired control and wireless control. When using wired control, it is necessary to select the button box installation position on the wall, and then arrange the connection line from the fire shutter controller to the wall button box installation position. This connection line needs to be grooved and pre-buried or covered with a metal pipe, and then a hole is punched through the wall at the button box installation position to install a manual control button box. This work is costly, inefficient, and inconvenient for batch debugging of fire shutters. Therefore, the remote control setting of the controller is more inclined to wireless control settings. The invention also needs to overcome the hidden dangers of battery replacement at the wireless control end. For example, Chinese patent invention patent CN116752886A discloses a fire shutter control method based on Bluetooth, which relates to the field of fire shutter technology and includes the following steps: S1: the controller is connected to the button box, the controller enters the first connection mode, and executes S2; S2: determines whether the controller has received the debugging application information from the debugging end. If so, the controller enters the second connection mode and executes S3; otherwise, no operation is performed; S3: the controller sends the parameters of the fire shutter and the button box to the debugging end; S4: the controller controls the fire shutter according to the debugging information. The present invention utilizes the characteristics of Bluetooth communication, sets a Bluetooth chip, completes the Bluetooth connection between the button box and the debugging end and the controller, and the Bluetooth chip of the button box has a low current in normal operation, effectively reduces power consumption, has a long service life, and is convenient for property management. During debugging, the controller enters a high-power mode to communicate with the debugging end, which is convenient for batch debugging of fire shutters and convenient for managers without professional experience to perform daily management.

[0005] However, the above-mentioned fire shutter control methods all have the following disadvantages: they adopt one-to-one one-way wireless control technology, that is, each fire shutter controller relies on a button box for debugging and control. Considering the large number of fire shutters in large supermarkets and factories, and the fire shutters in different areas will be zoned and controlled as the use stage progresses, the above-mentioned wireless control method requires many button boxes, and the control efficiency is low when multiple fire shutters are controlled in batches, and multiple fire shutters cannot be debugged and controlled in batches.

[0006] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable fire shutter partition control method based on wireless control. Summary of the Invention

[0007] The purpose of the present invention is to provide a fire shutter zoning control method based on wireless control. On the basis of ensuring wireless control and low energy consumption, the main control box performs zoning control on multiple sub-control boxes and fire shutters, and effectively utilizes the characteristics of wireless control. It can effectively connect multiple target sub-control boxes in the partition with the main control box, and the partition is variable, completing the zoning debugging and control of multiple sub-control boxes.

BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Figure 1 The present invention is a flow chart of a fire shutter zoning control method based on wireless control. DETAILED DESCRIPTION

[0033] The following are specific embodiments of the present invention, which further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0034] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of modules and structures set forth in these embodiments do not limit the scope of the present invention.

[0035] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0036] Technologies, methods, and systems known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, the technologies, methods, and systems should be considered part of the authorization specification.

[0037] Example 1: Figure 1 The figure is only one embodiment of the present invention, a fire shutter partition control method based on wireless control, comprising the following steps:

[0038] S1: Determine whether the main control box can be wirelessly connected to the button box. If so, the main control box enters the working mode and executes step S2; otherwise, no operation is performed;

[0039] The main control box is different from the sub-control box; the sub-control box, which is the fire shutter controller, is installed at the fire shutter motor and is used to control a single fire shutter, hereinafter referred to as the sub-control box; the main control box is used to establish a connection with one or more sub-control boxes to control one or more fire shutters as a central controller, hereinafter referred to as the main control box;

[0040] The button box is a wireless button box that can be installed on any wall or side wall of a beam within a certain distance around the controller. The height is generally set to 1.1 to 1.4 meters, which can not only avoid accidental touch but also facilitate the operation of the button box when needed. The main control box is set near the button box; there are several control buttons on the button box, including up button, down button, stop button, self-test button, etc. When the button on the button box is pressed, the button box transmits the control information to the sub-control box through the main control box, and the fire shutter is controlled up and down.

[0041] The button box and main control box are both installed on the wall and require battery power supply, while the sub-control box is directly powered by mains electricity together with the fireproof roller shutter;

[0042] In the present invention, the button box is wirelessly connected to the main control box, the main control box is wirelessly connected to the sub-control box, and the sub-control box is directly connected to the fireproof roller shutter motor through wires. One button box (or a group of two button boxes, respectively arranged on both sides of the wall) corresponds to one main control box, and one main control box corresponds to one or more sub-control boxes.

[0043] S2: Determine whether the main control box has received the debugging request information from the debugging terminal. If so, the main control box enters the partition mode and executes step S3; otherwise, directly execute step S4;

[0044] After the fire shutter has been used for a long time, on-site staff are required to debug the fire shutter at intervals. Generally, the staff will debug the fire shutter with a special debugging end.

[0045] Here, debugging includes: checking whether the fire shutter is working properly (whether it needs maintenance), checking whether the battery power of the main control box and button box is sufficient, and checking whether multiple fire shutters need to be re-partitioned.

[0046] In this application, the debugging end is a mobile terminal equipped with a Bluetooth APP, which is handheld and set up by the debugging personnel; the mobile terminal is equipped with a wireless connection chip, so when the debugging end is debugging, it first establishes a wireless connection between the debugging end and the main control box, and then uses the main control box as the target to debug the fire shutter;

[0047] In fact, when executing step S2, the debugging end is wirelessly connected to the main control box, and the debugging end sends a debugging request message to the main control box. The main control box enters the partition mode. At this time, the main control box feeds back the battery power of itself and the button box connected to it to the debugging end. The debugging personnel determines whether the battery power of the main control box and the button box is sufficient and whether the battery needs to be replaced. If so, it is replaced. Otherwise, debugging continues;

[0048] It should be noted that if the main control box is turned on for the first time, then the main control box does not establish a wireless connection with any sub-control box at this time, and the partition selection is directly performed to execute step S3; on the contrary, if the main control box is not turned on for the first time, that is, it is turned on after replacing the battery, then the main control box has a wireless connection with one or more sub-control boxes. At this time, the main control box will send the sub-control box numbers and the historical operating parameters of these sub-control boxes that are wirelessly connected to the main control box to the debugging end. The debugging personnel will determine whether these sub-control boxes and the fireproof roller shutters connected to them are working normally (whether they need maintenance). If maintenance is required, the maintenance personnel will be contacted; otherwise, debugging will continue; at this time, the debugging personnel will determine whether these sub-control boxes need to be re-partitioned. If so, step S3 will be executed; otherwise, step S4 will be directly executed, and the main control box will still perform partition control on the originally connected sub-control boxes.

[0049] S3: The debugging end debugs the sub-control box according to the debugging information sent by the sub-control box and establishes a wireless connection between the sub-control box and the main control box;

[0050] The debugging end takes the main control box as the center, sends debugging signals to the nearby sub-control boxes, debugs the sub-control boxes according to the debugging information sent by these sub-control boxes, and selects the target sub-control boxes for wireless connection with the main control box.

[0051] This step is actually to partition the sub-control boxes within the entire supermarket factory. If the main control box was originally connected to multiple sub-control boxes, then this is equivalent to re-partitioning, that is, the main control box will change the batch control sub-control box from now on. Of course, before this, disconnect the wireless connection between all sub-control boxes and the main control box.

[0052] S4: The main control box controls the sub-control box according to the sub-control box debugging information.

[0053] The main control box is now wirelessly connected to one or more sub-control boxes, and these sub-control boxes can be directly controlled in batches.

[0054] When executing step S4, the main control box performs batch control on at least one sub-control box according to the sub-control box debugging information.

[0055] Example 2: Still as Figure 1 The figure is only one of the embodiments of the present invention. Based on the first embodiment, the present invention provides a wireless control method for fireproof roller shutters. When executing step S3, the method specifically includes:

[0056] S31: The debugging terminal sends a debugging request to the nearby sub-control box;

[0057] S32: After receiving the debugging request, the sub-control box returns the sub-control box parameters and the fire shutter parameters connected to the sub-control box;

[0058] S33: The debugging end selects the target sub-control box according to the sub-control box parameters and sends a fire shutter debugging signal to the target sub-control box;

[0059] S34: The target sub-control box controls the fire shutter according to the fire shutter debugging signal and provides real-time feedback on the fire shutter operation information;

[0060] S35: The debugging end establishes a wireless connection between the target sub-control box and the main control box;

[0061] The debugging information transmitted from the sub-control box includes: sub-control box parameters, fire shutter parameters connected to the sub-control box, and fire shutter operation information.

[0062] Here, when executing step S32, the sub-control box parameters include the sub-control box number; the fire shutter parameters include the fire shutter number and the fire shutter position information.

[0063] When executing step S33, the number of target sub-control boxes selected is at least one.

[0064] And before executing step S35, disconnect the wireless connection between all sub-control boxes and the main control box.

[0065] Example 3: Still as Figure 1The figure shown is only one of the embodiments of the present invention. On the basis of any of the above embodiments, in a wireless control method for a fireproof roller shutter of the present invention, a first Bluetooth chip is provided in the main control box, and a second Bluetooth chip is provided in the button box; specifically, the first Bluetooth chip is provided on the circuit board of the main control box, and the second Bluetooth chip is provided on the circuit board of the wireless button box.

[0066] In addition, a third Bluetooth chip is provided in the debugging terminal, and a fourth Bluetooth chip is provided in the sub-control box;

[0067] In the present invention, the third Bluetooth chip and the fourth Bluetooth chip are Bluetooth chips that can enter a high-power mode, and the first Bluetooth chip and the second Bluetooth chip are merely conventional Bluetooth chips.

[0068] It's important to note that the current Bluetooth transmission range for commercial communications is between 80 and 100 meters, while the range for personal communication is around 10 meters. Bluetooth generally has two range specifications: Class A, used for high-power / long-range Bluetooth products, is costly and power-intensive, with a range of approximately 80 to 100 meters. Class B, the most popular standard, has a range of approximately 8 to 30 meters (typically around 10 meters), depending on the product design. It also consumes less power and is smaller, making it more portable.

[0069] Here, the third Bluetooth chip and the fourth Bluetooth chip have both Class A mode and Class B mode, and can switch between Class A mode and Class B mode; while the first Bluetooth chip and the second Bluetooth chip only have Class B mode; the third Bluetooth chip is directly connected to the AC power supply for the fireproof roller shutter, so there is no need to worry about power consumption; the main control box with the first Bluetooth chip and the button box with the second Bluetooth chip are installed on the wall and powered by batteries, so the first Bluetooth chip and the second Bluetooth chip in Class B mode have low power consumption, and the normal working current is only 10-20uA, the power supply is more durable, and there is no need to frequently replace the battery.

[0070] Then, when executing step S1, it is determined whether the first Bluetooth chip of the main control box can establish a Bluetooth connection with the second Bluetooth chip of the button box; if so, the first Bluetooth chip of the main control box and the second Bluetooth chip of the button box both enter the working mode, i.e., Class B mode, and step S2 is executed; otherwise, no operation is performed.

[0071] The debugging end is a mobile terminal equipped with a Bluetooth APP; the mobile terminal is equipped with a high-power Bluetooth communication chip; in fact, the high-power Bluetooth communication chip can enter Class A mode and has a Bluetooth communication distance of 80-100 meters; since the debugging end is a mobile terminal that can be charged and maintained daily, there is no need to worry about power consumption. You can enter high-power mode during debugging and charge it after debugging is completed.

[0072] When executing step S2, it is determined whether the first Bluetooth chip of the main control box can establish a Bluetooth connection with the third Bluetooth chip of the debugging end and receive the debugging request information sent by the third Bluetooth chip of the debugging end. If so, the main control box enters the partition mode, and the third Bluetooth chip in the debugging end enters the Class A mode, and step S3 is executed; otherwise, step S4 is directly executed.

[0073] When the sub-control box is being debugged with the debugging terminal, the fourth Bluetooth chip in the sub-control box also enters Class A mode. The sub-control box and the fire shutter are powered by the same mains power, so there is no need to worry about the fourth Bluetooth chip in Class A mode consuming a lot of power.

[0074] When executing step S3, a wireless connection is established between the fourth Bluetooth chip in the sub-control box and the first Bluetooth chip in the main control box. After the connection is completed, the fourth Bluetooth chip returns to Class B mode and connects to the first Bluetooth chip via Bluetooth. The main control box is also re-partitioned and managed, and returns to working mode.

[0075] At this time, step S4 is executed, and the main control box performs batch control on at least one sub-control box according to the sub-control box debugging information.

[0076] In addition, the debugging end can check multiple sub-control boxes for debugging at the same time, or wirelessly connect multiple sub-control boxes to the main control box at the same time. Then these sub-control boxes will be partitioned and controlled in batches by the main control box. Similarly, the debugging end will partition all the sub-control boxes in the supermarket or factory and host them to multiple main control boxes respectively. Multiple main control boxes will manage the sub-control boxes in the areas they are connected to for fire shutter control.

[0077] Finally, the third Bluetooth chip and the fourth Bluetooth chip are both CC2540 Bluetooth chips, which have both Class A mode and Class B mode and can switch between Class A mode and Class B mode.

[0078] The present invention provides a fire shutter zoning control method based on wireless control. On the basis of ensuring wireless control and low energy consumption, a main control box performs zoning control on multiple sub-control boxes and fire shutters, and effectively utilizes the characteristics of wireless control. Multiple target sub-control boxes in the partition can be effectively connected to the main control box, and the partitions are variable, thereby completing the zoning debugging and control of multiple sub-control boxes.

[0079] The present invention is not limited to the above specific embodiments, and various modifications and variations are possible. Any modification, equivalent replacement, improvement, etc. made to the above embodiments based on the technical essence of the present invention shall be included in the scope of protection of the present invention.
