Description

Technical Field

[0001] The present invention relates to the technical field of installation and control of fire-fighting water cannons, and in particular to an intelligent water cannon address adjustment system and an adjustment method thereof. Background Art

[0002] Fire water monitors are used for on-site monitoring and handling of large space fires. As the country's requirements for fire protection gradually increase, many workshops, factories, exhibition halls, waiting halls and other large spaces have intelligent fire water monitors installed under the roof. Figure 3 As shown, it can automatically detect the fire source and spray water to extinguish the fire. The manual control of the intelligent water cannon is generally through its control box (such as Figure 4 ) to control, and use the control box to adjust the rotation and spray direction of the water cannon. Due to the limitations of installation spacing and the operator's visual range, the number of smart water cannons that can be controlled by a control box is limited. Generally, a control box can control 2-6 smart water cannons. Too many will exceed the human visual range and do not meet the relevant requirements of fire protection.

[0003] When the water cannon manufacturer produces, the water cannon and its control box will be grouped. Each control box will have N water cannons to form a group, and the communication addresses of these N water cannons will be written and set, such as 1, 2, 3, ... respectively represent the communication addresses of each water cannon in each group. For large-scale installation sites, multiple groups of water cannons need to be installed. The problem now is that when multiple groups of water cannons and their control boxes arrive at the installation site, the installers ignore the grouping and confuse the water cannons of different groups. For example, the water cannons with the communication address of No. 1 in different groups are installed under the same control box. After the installation is completed, this problem will not be discovered until debugging, resulting in water cannons with duplicate addresses in some groups, which will cause obstacles to the control communication between the water cannons and the control box, and normal communication and manual control cannot be achieved. It is necessary to re-write and set the addresses of each water cannon in some groups after installation before normal communication and control can be achieved. After the water cannon is installed, the shell has been sealed, and the adjustment and setting of the address require opening the shell to operate the internal control panel in the prior art. It is troublesome, dangerous and inefficient to disassemble and assemble the shell at high altitude. It is necessary to propose a simpler method to solve this problem. Summary of the invention

[0004] In order to solve the problem of communication address confusion of the above-mentioned intelligent water cannon, the present application proposes an intelligent water cannon address adjustment system and an adjustment method thereof.

[0005] The technical solution of the present invention is: an intelligent water cannon address adjustment system, which at least includes a control panel in the water cannon and a limit switch for controlling the rotation limit position of the water cannon barrel in the vertical plane. A water cannon address setting module is embedded in the control panel, and the setting module can be in the form of hardware or in the form of a soft program written on the control panel. The limit switch is connected to the control panel via a wire, and the limit switch provides a signal to the water cannon address setting module in the control panel for setting the address of the water cannon. After the communication address of the water cannon is set, the address is stored in the corresponding water cannon address storage unit for calling during communication.

[0006] Preferably, the housing of the intelligent water cannon is provided with an arc-shaped notch for the water cannon barrel to swing vertically, the water cannon barrel extends from the arc-shaped notch and swings vertically in the arc-shaped notch, a limit switch is installed in the arc-shaped notch, and the limit switch is touched or approached through the arc-shaped notch. The touching process is to touch the limit switch manually through the arc-shaped notch with a finger or a tool, and the limit switch can be a contact micro switch or an inductive proximity switch.

[0007] Preferably, the water monitor address setting module is a switch signal frequency setting module, or a switch signal duration setting module.

[0008] A method for adjusting the address of a water cannon using the aforementioned intelligent water cannon address adjustment system, the method comprising the following steps: 1). Power on After the water monitor has completed the structural installation and the wiring harness connection installation, the water monitor is powered on; after the power is turned on, the strong and weak current parts of the water monitor are both in the powered-on state, and the address setting module starts running at this time; 2). The limit switch gives a signal Within the limited time t after power-on, if someone touches the limit switch or delivers a sensing object to the limit switch, the limit switch will give a signal, which is considered a human signal; t≥12 seconds 3). Set a new water cannon address If the control board receives the signal within the limited time t after power-on, the water cannon address setting module will be started to run, and the communication address of the intelligent water cannon will be reset according to the type of limit switch signal. If the signal is not received within the limited time t, the communication address will not be reset and the water cannon will enter the standby state.

[0009] Preferably, the water cannon address setting module is a switch signal number setting module. Within a limited time t, the limit switch is manually triggered to give n trigger signals. The address setting module receives the signal and sets the water cannon address to the nth water cannon, where n≥1. The water cannon address is set by the number of triggering times of the limit switch. If it is triggered once, its address is set to 1, or a coding address related to 1; if it is triggered twice, its address is set to 2, or a coding address related to 2; if it is triggered three times, its address is set to 3, or a coding address related to 3. The addresses of other intelligent water cannons are set by analogy.

[0010] Preferably, the water cannon address setting module is a switch signal duration setting module. Within the limited time t, the limit switch gives a signal with a duration greater than (m-1)*t1 and less than or equal to m*t1. The address setting module sets the water cannon address to the mth water cannon, m≥1, 3 seconds≤t1≤6 seconds, t>m*t1. The duration of the triggering of the limit switch, that is, the on time, gives a connection signal for a certain period of time. The water cannon address of the limit switch contact duration within the time of 0-t1 is set to 1 or a coding address related to 1; the water cannon address of the limit switch contact duration within the time of t1-2t1 is set to 2 or a coding address related to 2; and the addresses of other intelligent water cannons are set in the same way.

During the setting process, different new communication addresses are set for each water cannon according to the different types of trigger signals of the limit switches on different intelligent water cannons. The address is used to communicate with the control box. The limit switch is a limit switch for controlling the rotation limit position of the water cannon barrel in the vertical plane. It is in an exposed position and easy to touch. The implementation of the system and method only requires the program of the water cannon address setting module to be embedded in the control panel in advance. The program module is run within the time t when the water cannon is powered on. The limit switch is in a contactable position, and there is no need to remove the shell of the water cannon. Compared with the original control panel jumper method to modify the address, it is simpler and safer, and more efficient. The process can be basically completed in 20 seconds to 1 minute after the water cannon is powered on. BRIEF DESCRIPTION OF THE DRAWINGS
