Description

Technical Field

[0001] The utility model relates to the technical field of intelligent buildings, in particular to a fire valve control and signal feedback debugging device. Background Art

[0002] Article 13.4.4 of GB51348-2019 "Electrical Design Standard for Civil Buildings" and Section 4.5 of GB50166-2013 "Design Code for Automatic Fire Alarm Systems" put forward requirements for closing signal feedback and electric control switches for fire dampers installed at the outlets of air-conditioning ventilation ducts and fire dampers in smoke and exhaust systems. This requirement is achieved through the linkage and cooperation of the automatic fire alarm system (hereinafter referred to as FAS) installed in the building. Manufacturers usually set the relevant electrical control and signal feedback terminals on or near the fire damper actuator.

[0003] According to the current common practice on construction sites, the installation and debugging of fire dampers are carried out by ventilation and air conditioning professionals. It is easy for installation workers to conduct and intuitively judge whether the manual operation of the fire dampers is convenient, flexible and reliable after the installation is completed. However, due to the limitations of debugging tools and professional knowledge barriers, the fire damper installation construction workers cannot test the fire dampers separately after the installation is completed. Usually, the coordinated debugging is started after the automatic fire alarm system is powered on and running. This is equivalent to combining the independent electrical function test of the fire dampers with the interface function debugging of the automatic fire alarm system and the fire dampers. This brings potential problems of the fire dampers that should have been eliminated in the independent electrical function test to the interface debugging. When there are a large number of fire dampers, the efficiency and progress of the interface debugging are seriously affected. Furthermore, during the coordinated commissioning of the fire dampers and the automatic fire alarm system, problems were discovered with the fire dampers themselves. At this point, construction had already been largely completed across all disciplines on the construction site. The building's overhead pipelines were crisscrossed, and the fire dampers were installed high in the air ducts, with limited access. This made troubleshooting difficult, time-consuming, and inefficient, especially in areas with suspended ceilings or high ceilings. This required high-altitude work, posing a significant safety hazard. Currently, on-site fire dampers can only be tested manually; there are no simple tools to test their electrical control and feedback functions, a significant industry hurdle.

[0043] The active debugging circuit also includes a second test circuit and a second wiring terminal;

[0044] The second test circuit includes a second series circuit consisting of a diode and an R2 resistor 11 connected in series;

[0045] The second series circuit is connected in parallel with a third series circuit formed by connecting the power supply and the SW1 switch 7 in series, forming a parallel circuit;

[0051] The passive test circuit includes a SW2 switch 14, a KY+ terminal 15 and a KY- terminal 16;

[0052] One end of the SW2 switch 14 is connected to the KY+ terminal 15 , and the other end of the SW2 switch 14 is connected to the KY− terminal 16 .

[0053] Among them, the principle of this application is as follows: the switching status output terminal of the fire damper corresponds to a group of passive normally open or normally closed dry nodes controlled by the mechanical structure inside its actuator. The signals required by the control action terminal of the fire damper are divided into two categories. One is that the fire damper actuator has an independent power supply. At this time, the signal required between the two terminals of the control action is to connect or disconnect the two terminals externally; the other is that the fire damper actuator has no independent power supply. When a DC24V voltage is applied between the two terminals of the control drive, the fire damper (actuator) is electrically actuated.

[0054] In order to intuitively and independently reflect the switch status signal, a fire damper switch status LED light (working current 20mA, voltage 3.2V) is set in the debugging device to light up the circuit. Connect the switch status output terminal of the fire damper actuator terminal to the S+ terminal and S- terminal. Close the SW1 switch and manually or electrically open and close the fire damper. The switch status of the fire damper can be judged by the on and off of the lamp bead:

[0055] 1. When the switch status output terminal in the fire damper actuator wiring terminal is a normally closed dry node, close the SW1 switch, the fire damper opens, the LED lights up, and the fire damper closes, the LED lights off. The fire damper signal feedback function is normal, otherwise the fire damper signal feedback function is abnormal.

[0056] 2. When the switch status output terminal in the fire damper actuator wiring terminal is a normally open dry node, close the SW1 switch, the fire damper opens, and the LED light is off; when the fire damper is closed, the LED light is on, then the fire damper signal feedback function is normal; otherwise, the fire damper signal feedback function is abnormal.

[0057] Before using the device, do not connect the actuator terminals of the fire damper to the test device. First close the SW1 switch, and then close the self-test switch SW3. If the LED light is on, it proves that the test circuit is normal, otherwise the test circuit is damaged, and then disconnect the SW1 and SW3 switches.

[0058] In addition, a DC24V power supply is led to the SP+ terminal and the SP- terminal, through which the fire damper actuator is provided with an independent working power supply or an action power supply. The self-holding button SW1 switch is an external output power supply or an action test switch.

[0059] The KY+ terminal and the KY- terminal are a group of controlled passive dry nodes. When in use, connect the two terminals of the actuator control action powered by an independent power supply to the KY+ terminal and the KY- terminal with a test circuit, and press the self-holding button SW2 to drive the fire damper to operate.

[0060] The fire damper control function test process is as follows (all cables are wired as if completed):

[0061] 1. When the fire damper actuator needs to be provided with an independent working power supply, the SP+ and SP- terminals provide it with an independent working power supply. After pressing SW1, press SW2. If the fire damper body moves electrically and the fire damper switch status indicator on the test device changes accordingly, the fire damper control and signal feedback functions are normal, otherwise it is abnormal;

[0062] 2. When the fire damper actuator has no independent power supply, connect the SP+ and SP- terminals to the fire damper actuator control drive terminals. After pressing SW1, if the fire damper body moves electrically and the fire damper switch status indicator on the test device changes accordingly, the fire damper control and signal feedback functions are normal, otherwise it is abnormal;

[0063] Resistor R1 is a 1kΩ current-limiting resistor. Diode D1 and resistor R2 form a freewheeling circuit, dissipating energy and preventing the 24V DC power supply from being damaged by the reverse high voltage generated when the fire damper actuator's solenoid coil is de-energized. FU is a 1A fuse to prevent power short circuits. In practice, the 24V DC power supply is provided by a rechargeable lithium battery in conjunction with a boost module.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
