Description

Technical Field

[0001] This invention relates to the field of fireproof roller shutter technology, and in particular, to a Bluetooth-based fireproof roller shutter control method. Background Technology

[0002] With the country's large-scale infrastructure construction (such as subways, airport expansions and renovations, and stadiums), the demand for roller shutters used in buildings is increasing, and the performance requirements are becoming more stringent. In these important locations, the fire alarm level requirements are becoming increasingly stringent; currently, densely populated shopping malls, underground rail transit, underground parking lots, and factories mostly use fire-resistant roller shutters for fire control by opening or closing them.

[0003] However, the motors and controllers for fire-resistant roller shutters are typically located high above the door, making the opening and closing of the shutters cumbersome. Furthermore, each fire-resistant roller shutter can be opened and closed independently, often requiring individual testing of each shutter's controller. For example, Chinese invention patent CN105182963A describes a testing device for a fire-resistant roller shutter controller, comprising a main body, an analog control section, and a panel mounted on the main body. The analog control section includes an analog power supply and control unit, an analog load unit, an electrical parameter testing unit, an analog smoke and temperature unit, an analog full-descent and half-descent unit, and an operational feedback unit, all connected to the fire-resistant roller shutter controller. It also includes a switching power supply unit that provides DC voltage to the analog power supply and control unit and the operational feedback unit. This invention provides a testing device for fire-resistant roller shutter controllers, which not only improves work efficiency but also addresses personnel safety hazards. It allows for comprehensive testing of the controller's functions, saving costs and increasing production efficiency. There is an urgent need to develop a method for mass-producing and testing fire-resistant roller shutters.

[0004] Furthermore, with increasingly stringent requirements for remote control of fire-resistant roller shutters, many fire-resistant roller shutters are now equipped with remote control button boxes. Remote control methods are divided into wired and wireless control. For wired control, a button box installation location needs to be selected on the wall, and then a connecting cable needs to be laid from the fire-resistant roller shutter controller to the wall button box installation location. This connecting cable needs to be pre-embedded in grooves or fitted with metal conduits. Then, a hole needs to be drilled through the wall at the button box installation location to install the manual control button box. This work is costly, inefficient, and inconvenient for batch testing of fire-resistant roller shutters. Therefore, for remote control... The control settings for the controller are more biased towards wireless control. For example, Chinese Utility Model Patent CN203684998U discloses a wireless button box for a fireproof roller shutter controller. The fireproof roller shutter main unit has a main unit wireless transmission and reception circuit; the electronic lock box is a wireless button box. The wireless button box has a microcontroller unit (MCU) connected to a mechanical lock, a set of buttons, an indicator light, and a button box wireless transmission and reception circuit matched with the main unit's wireless transmission and reception circuit. This enables bidirectional transmission and reception between the electronic lock box and the fireproof roller shutter door, and the execution of corresponding actions. The MCU intermittently controls the opening and closing of the button box's wireless transmission and reception circuit. This utility model's wireless button box is battery-powered and communicates wirelessly with the fireproof roller shutter main unit, enabling all the functions of the wireless button box paired with the fireproof roller shutter main unit. Simultaneously, by intermittently opening the button box's wireless transmission and reception circuit through the MCU, ultra-low power consumption is achieved, extending battery standby time.

[0005] However, the above-mentioned fireproof roller shutter control methods all have the following drawbacks: the wireless connection between the controller and the wireless button box consumes a lot of power. The controller is connected to the mains power and there is no power shortage, but the wireless button box is set up separately and uses battery power. It often runs out of power after one or two years and requires frequent battery replacement. Generally, there are a lot of fireproof roller shutters and wireless button boxes in large shopping malls. After the fireproof roller shutters and wireless button boxes are installed, they need to be handed over to the shopping mall property management for management. It is difficult for the shopping mall property management to replace the batteries of the wireless button boxes frequently over a long period of time, which leads to safety hazards. In addition, ordinary wireless control still cannot perform large-scale debugging of fireproof roller shutters.

[0006] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable Bluetooth-based fireproof roller shutter control method. Summary of the Invention

[0007] The purpose of this invention is to provide a Bluetooth-based fireproof roller shutter control method. Utilizing the characteristics of Bluetooth communication, a Bluetooth chip is set up to complete the Bluetooth connection between the controller and the button box, as well as the Bluetooth connection between the controller and the debugging terminal. The Bluetooth chip in the button box has low current consumption under normal conditions, effectively reducing power consumption, and has a long service life, which is convenient for property management. Moreover, during debugging, the controller enters a high-power mode to communicate with the debugging terminal, which facilitates batch debugging of fireproof roller shutters and makes daily management easier for managers without professional experience.

[0008] To achieve the above objectives, the present invention employs the following technical solution:

[0009] A Bluetooth-based fireproof roller shutter control method includes the following steps:

[0010] S1: Determine whether the fireproof roller shutter controller can wirelessly connect to the button box. If it can, the fireproof roller shutter controller enters the first connection mode and executes step S2; otherwise, no operation is performed.

[0011] S2: Determine whether the fireproof roller shutter controller has received the debugging request information from the debugging terminal. If yes, the fireproof roller shutter controller enters the second connection mode and executes step S3; otherwise, no operation is performed.

[0012] S3: The fireproof roller shutter controller sends the operating parameters of the fireproof roller shutter and button box to the debugging terminal;

[0013] S4: The fireproof roller shutter controller controls the fireproof roller shutter based on the debugging information received from the debugging terminal.

[0014] As a preferred embodiment of the present invention, a first Bluetooth chip is provided in the fireproof roller shutter controller and a second Bluetooth chip is provided in the button box.

[0015] When executing step S1, it is determined whether the first Bluetooth chip of the fireproof roller shutter controller can connect with the second Bluetooth chip of the button box via Bluetooth; if it can, the fireproof roller shutter controller enters the first connection mode and executes step S2; otherwise, no operation is performed.

[0016] As a preferred embodiment of the present invention, the first connection mode is Bluetooth communication mode;

[0017] When executing step S1, the fireproof roller shutter controller enters the first connection mode. The first Bluetooth chip sends a communication signal to the second Bluetooth chip at a first predetermined time interval. It is determined whether the first Bluetooth chip can receive the feedback signal from the second Bluetooth chip after the communication signal is sent. If so, the feedback signal is stored; otherwise, an alarm is issued.

[0018] As a preferred embodiment of the present invention, the button box is provided with a power supply for powering the second Bluetooth chip, and the feedback signal of the second Bluetooth chip includes the remaining power of the power supply.

[0019] As a preferred embodiment of the present invention, the debugging terminal is a mobile terminal equipped with a Bluetooth APP; the mobile terminal is equipped with a high-power Bluetooth communication chip;

[0020] When executing step S2, the debugging terminal uses the Bluetooth APP to call the high-power Bluetooth communication chip to send debugging request information via high-power Bluetooth communication.

[0021] As a preferred embodiment of the present invention, the second connection mode is a high-power Bluetooth communication mode.

[0022] As a preferred embodiment of the present invention, when performing step S3, the fireproof roller shutter controller sends the parameters and status of the fireproof roller shutter, as well as the working status of the button box and the remaining power of the power supply, to the debugging terminal via the first Bluetooth chip in the form of high-power Bluetooth communication.

[0023] As a preferred embodiment of the present invention, when performing step S3: the fireproof roller shutter controller sends the fireproof roller shutter number to the debugging terminal;

[0024] When performing step S4, the debugging terminal simultaneously sends debugging information to multiple fireproof roller shutters. The debugging information includes the target fireproof roller shutter number. When the fireproof roller shutter controller receives the debugging information, it determines whether the target fireproof roller shutter number in the debugging information includes its own fireproof roller shutter number. If so, it controls the fireproof roller shutter according to the debugging information; otherwise, it does not perform any operation.

[0025] As a preferred embodiment of the present invention, the first Bluetooth chip is a CC2540 Bluetooth chip.

[0026] The beneficial effects of the Bluetooth-based fireproof roller shutter control method of the present invention are as follows:

[0027] By utilizing the characteristics of Bluetooth communication, a Bluetooth chip is set up to complete the Bluetooth connection between the controller and the button box, as well as the Bluetooth connection between the controller and the debugging terminal. The Bluetooth chip in the button box has low current consumption under normal conditions, effectively reducing power consumption and extending its service life, which is convenient for property management. During debugging, the controller enters a high-power mode to communicate with the debugging terminal, which facilitates batch debugging of fireproof roller shutters and makes daily management easier for managers without professional experience. Attached Figure Description

[0028] Figure 1 This is a flowchart illustrating a Bluetooth-based fireproof roller shutter control method according to the present invention. Detailed Implementation

[0029] The following are specific embodiments of the present invention, which further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] 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 arrangement of modules and structures set forth in these embodiments does not limit the scope of the invention.

[0031] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0032] Techniques, methods, and systems known to a person skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the license specification.

[0033] Example 1: As Figure 1 The illustration shown is merely one embodiment of the present invention. A Bluetooth-based fireproof roller shutter control method includes the following steps:

[0034] S1: Determine whether the fireproof roller shutter controller can wirelessly connect to the button box. If it can, the fireproof roller shutter controller enters the first connection mode and executes step S2; otherwise, no operation is performed.

[0035] The fireproof roller shutter controller is located at the fireproof roller shutter motor, hereinafter referred to as the controller; while the button box is a wireless button box, which can be installed on the side wall of any wall or beam within a certain distance around the controller, generally at a height of 1.1 to 1.4 meters. This avoids accidental touches and allows for convenient operation of the button box when needed. The button box is equipped with several control buttons, including an up button, a down button, a stop button, a self-test button, etc. When a button on the button box is pressed, the button box wirelessly connects with the controller to transmit control information to the controller, and the fireproof roller shutter performs up and down control.

[0036] In this application, a first Bluetooth chip is installed in the fireproof roller shutter controller, and a second Bluetooth chip is installed in the button box. Specifically, the first Bluetooth chip is installed on the circuit board of the fireproof roller shutter controller, and the second Bluetooth chip is installed on the circuit board of the wireless button box. The first Bluetooth chip is directly connected to the mains power supply of the fireproof roller shutter, so there is no need to worry about power consumption. The second Bluetooth chip is installed in the button box and is powered by a battery.

[0037] Therefore, the first Bluetooth chip is configured to enter high-power mode, while the second Bluetooth chip is just a regular Bluetooth chip.

[0038] It should be noted that the current Bluetooth transmission distance for commercial communication is between 80 and 100 meters, while the Bluetooth transmission distance for personal communication is around 10 meters. In other words, Bluetooth generally has two communication distance versions: Class A; used in high-power / long-range Bluetooth products, it is expensive and consumes a lot of power, with a communication distance of approximately 80-100 meters; Class B; is currently the most popular standard, with a communication distance of approximately 8-30 meters (usually around 10 meters), depending on the product design, with lower power consumption and smaller size, making it easy to carry.

[0039] Here, the first Bluetooth chip has both Class A and Class B modes and can switch between them; while the second Bluetooth chip only has Class B mode. The first Bluetooth chip is directly connected to the AC power supply of the fireproof roller shutter, so there is no need to worry about power consumption. The second Bluetooth chip in Class B mode has low power consumption, with a normal operating current of only 10-20uA, making the power supply more durable and eliminating the need for frequent battery replacements.

[0040] When executing step S1, it is determined whether the first Bluetooth chip of the fireproof roller shutter controller can connect with the second Bluetooth chip of the button box via Bluetooth. If it can, the first Bluetooth chip of the fireproof roller shutter controller enters the first connection mode, i.e., Class B mode, and executes step S2; otherwise, no operation is performed.

[0041] S2: Determine whether the fireproof roller shutter controller has received the debugging request information from the debugging terminal. If yes, the fireproof roller shutter controller enters the second connection mode and executes step S3; otherwise, no operation is performed.

[0042] After prolonged use, fireproof roller shutters require on-site staff to periodically adjust them. This is typically done by staff using a special adjustment tool.

[0043] In this application, the debugging end is a mobile terminal 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 only 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, and it can enter high-power mode during debugging, and can be charged after debugging is completed.

[0044] When executing step S2, the debugging terminal calls the high-power Bluetooth communication chip through the Bluetooth APP to send debugging request information in the form of high-power Bluetooth communication. After the staff opens the Bluetooth APP and logs in, they can initiate a connection with the first Bluetooth chip based on the high-power Bluetooth communication chip, establish a Bluetooth connection with the fireproof roller shutter controller, and then send debugging request information to all fireproof roller shutter controllers within the communication range.

[0045] And when the fireproof roller shutter controller receives the debugging request information from the debugging terminal during step S1, the first Bluetooth chip of the fireproof roller shutter controller enters the second connection mode, namely the high-power Bluetooth communication mode (Class A mode), and executes step S3.

[0046] S3: The fireproof roller shutter controller sends the operating parameters of the fireproof roller shutter and button box to the debugging terminal;

[0047] Since the first Bluetooth chip of the fireproof roller shutter controller also enters high-power mode at this time, with a Bluetooth communication distance of 80-100 meters, as long as the first Bluetooth chip can receive the debugging request information, it can also connect to the debugging end. At this time, the first Bluetooth chip, which has entered high-power mode, can send the working parameters of the fireproof roller shutter and the button box to the debugging end.

[0048] Specifically, when executing step S3, the fireproof roller shutter controller sends the parameters and status of the fireproof roller shutter, as well as the working status of the button box and the remaining power of the power supply, to the debugging terminal via the first Bluetooth chip using high-power Bluetooth communication.

[0049] Of course, when executing step S3, the fireproof roller shutter controller will also add its own fireproof roller shutter number to the parameter data and send it to the debugging terminal.

[0050] S4: The fireproof roller shutter controller controls the fireproof roller shutter based on the debugging information received from the debugging terminal.

[0051] After receiving the parameter data from the first Bluetooth chip, the staff will check it. If there is a safety hazard, they will report it for repair in time. If there is no safety hazard, there is no need for warranty. The staff will control the fireproof roller shutter according to its status, such as controlling the fireproof roller shutter to move up and down once. The staff will further judge whether the fireproof roller shutter is operating safely based on the data transmitted in real time from the first Bluetooth chip.

[0052] Of course, when executing step S4, the debugging terminal sends debugging information to multiple fireproof roller shutters at the same time. The debugging information includes the target fireproof roller shutter number. When the fireproof roller shutter controller receives the debugging information, it determines whether the target fireproof roller shutter number in the debugging information includes its own fireproof roller shutter number. If so, it controls the fireproof roller shutter according to the debugging information; otherwise, it does not perform the operation.

[0053] In other words, the debugging terminal can simultaneously select multiple fireproof roller shutter controls and debug multiple fireproof roller shutters at the same time.

[0054] In summary, the key point of this application is that the first Bluetooth chip can be connected to the button box in Class B mode to ensure that the button box has low power consumption and long service life, and can also be connected to the debugging terminal in Class A mode for batch debugging, which is convenient for property management.

[0055] Example 2: As before Figure 1 The illustration shown is merely one embodiment of the present invention. Based on Embodiment 1, the present invention provides a wireless control method for fireproof roller shutters.

[0056] The first connection mode is the normal Bluetooth communication mode (Class B mode).

[0057] When executing step S1, the fireproof roller shutter controller enters the first connection mode. The first Bluetooth chip sends a communication signal to the second Bluetooth chip at a first predetermined time interval. It is determined whether the first Bluetooth chip can receive the feedback signal from the second Bluetooth chip after the communication signal is sent. If so, the feedback signal is stored; otherwise, an alarm is issued.

[0058] Meanwhile, the button box contains a power supply for powering the second Bluetooth chip, and the feedback signal from the second Bluetooth chip includes the remaining power level of the power supply.

[0059] It is important to note that the second Bluetooth chip inside the button box does not need to go into sleep mode. Instead, the second Bluetooth chip is kept in a working state by locking the button in the button box with the second Bluetooth chip. In effect, this disconnects the signal communication between the circuit board and the second Bluetooth chip. Even if someone operates the button and there is current on the circuit board, the second Bluetooth chip will not process this current. Therefore, there is no control information to be transmitted to the first Bluetooth chip to make the fireproof roller shutter run.

[0060] Furthermore, the circuit board and the second Bluetooth chip only communicate after the second Bluetooth chip receives the unlock signal. The unlock signal includes passive unlocking, which means that the staff can unlock the locked state of the communication between the first wireless chip and the button box by using the unlock button on the button box; and active unlocking, which means that the first Bluetooth chip of the fireproof roller shutter controller sends an emergency unlock signal. That is, after the fireproof roller shutter controller receives fire alarm information (including abnormal detection of temperature probe, abnormal detection of smoke probe and 119 fire alarm notification information), the first Bluetooth chip sends an unlock notification to the second Bluetooth chip, and the second Bluetooth chip can respond quickly (within 3 seconds) to unlock, so as to facilitate the escape of personnel.

[0061] In this way, the second Bluetooth chip has low power consumption characteristics. Although it is always working, its operating current is only 10uA. Compared with the large current of 2-3A required for activation during normal sleep and special periods, it can still reduce the total power consumption. In addition, the use of a large-capacity, long-life battery can effectively reduce the frequency of battery replacement. The long-life battery refers to a battery with sufficient power that will not abnormally lose power after long-term use. For example, a long-life lead paste battery with antimony oxide is added. Multiple AAA batteries can also be connected in series, which is low in cost and has sufficient power, making it convenient for large-scale use.

[0062] Finally, the first Bluetooth chip is a CC2540 Bluetooth chip, which has both Class A and Class B modes and can switch between Class A and Class B modes.

[0063] This invention discloses a Bluetooth-based fireproof roller shutter control method. It employs a wireless chip to achieve wireless connection between the controller and the button box. The wireless chip at the button box is always operational, drawing minimal current under normal conditions. It merely locks the communication between the wireless chip and the button box, effectively unlocking upon the arrival of an unlock signal. The circuit is simple and requires no large current for unlocking, reducing the button box's power consumption and extending its lifespan. Combined with a long-life battery, it can last for 5-10 years without needing battery replacement, facilitating property management. Furthermore, it can easily unlock within 3 seconds in emergencies, ensuring high security.

[0064] This invention is not limited to the specific embodiments described above, and various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made to the above embodiments based on the technical essence of this invention should be included within the scope of protection of this invention.
