Description

Technical Field

[0001] The present invention belongs to the technical field of building fire protection, and particularly relates to an evacuation lighting system and a rapid linkage control method therefor. Background Art

[0002] In various civil buildings, the evacuation lighting system is a building fire protection system that assists personnel evacuation and fire fighting operations, and is composed of fire emergency lighting fixtures and related devices. Its functions are twofold: one is to provide necessary lighting for personnel evacuation and fire rescue in case of a fire; the other is to provide necessary lighting for personnel evacuation in case of failure of normal lighting. The emergency lighting fixtures in the evacuation lighting system are in a non-emergency state under normal conditions. When a fire occurs or an emergency such as the failure of normal lighting occurs in a building, the evacuation lighting system performs linkage control on the fire emergency lighting fixtures to quickly enter the emergency state.

[0003] Currently, there are only two methods for the linkage control of the evacuation lighting system products supplied on the market: (1) The linkage control method implemented by the emergency lighting controller sending (broadcasting) instructions and data through the communication port, and the emergency lighting centralized power supply receiving the instructions and data. The problems are: low reliability and slow linkage control speed. On the one hand, this method completely relies on digital communication. In case of a fire or other extreme situations, the randomly generated electromagnetic interference will cause the communication failure of the fire emergency lighting fixtures and related devices in the evacuation lighting system, resulting in the failure of linkage control; on the other hand, during the communication process, not only do multiple bytes of instructions and data need to be transmitted between the MCUs in each fire emergency lighting fixture and related components, but the MCU also needs to perform data exchange and logical judgment, resulting in a long linkage conversion time. For example, in a crowded stairwell without natural light, if the normal lighting suddenly fails, the long linkage conversion time will cause the fire emergency lighting fixtures in the stairwell to enter the emergency state late. The stairwell will be dark for a certain period of time after the normal lighting fixtures go out, which may cause people in the stairwell to fall and stampede; (2) The linkage control method implemented by directly monitoring the mains power state by introducing the power supply circuit of the mains distribution box into the mains monitoring terminal of the emergency lighting centralized power supply. The problem is: difficult construction for wire laying. For example, in the interval tunnels of the subway, the number of normal lighting distribution boxes is large, they are scattered and far away, making it inconvenient or impossible to lay the wires for monitoring between the normal lighting distribution box and the emergency lighting centralized power supply, resulting in the inapplicability of this linkage control method in special civil buildings. Summary of the Invention

[0004] The object of the present invention is to study a fast linkage control method for the problems of the above-mentioned existing technology products, and an evacuation lighting system with a fast linkage control function established according to the method. The method and system can realize the function that the evacuation lighting system can quickly and reliably emergency start fire emergency lamps when a fire occurs or normal lighting fails; it can achieve the purpose of overcoming the difficulty of wire laying and reducing construction costs. The technical solution of the present invention is as follows:

[0005] An evacuation lighting system with a fast linkage control function, as Figure 1 shown, the system includes an emergency lighting controller 1, an emergency lighting centralized power supply 3, fire emergency lamps 4, a wired remote interface module 5, a wired linkage module 6, a light sensor 7, a light linkage module 8, a wireless interface module 9 and a wireless linkage module 10;

[0006] The communication port of the emergency lighting controller 1 is connected to the communication port of the emergency lighting centralized power supply 3 through a twisted pair 2, and the power distribution output end of the emergency lighting centralized power supply 3 is connected to the fire emergency lamps 4; the wired remote interface module 5 is arranged on the twisted pair 2; the level signal input end of the wired linkage module 6 is connected to the twisted pair 2, and the output end of the wired linkage module 6 is connected to the linkage input port of the emergency lighting centralized power supply 3;

[0007] The output end of the light sensor 7 is connected to the light input end of the light linkage module 8, and the output end of the light linkage module 8 is connected to the linkage input port of the emergency lighting centralized power supply 3; the number of the light sensors 7 is several, and the output ends of several light sensors 7 are connected in parallel to realize parallel redundant monitoring;

[0008] The wireless interface module 9 is connected to the wireless linkage module 10 through a wireless channel, and the output end of the wireless linkage module 10 is connected to the linkage input port of the emergency lighting centralized power supply 3; the number of the wireless interface modules 9 is several, and several wireless interface modules 9 are respectively arranged in different normal lighting distribution boxes to realize multi-point linkage control;

[0009] The wired remote interface module 5 is configured with 4-way mains monitoring wiring terminals, and the mains monitoring wiring terminals of the wired remote interface module 5 are connected in parallel with the detected circuit in the normal lighting distribution box; the wireless interface module 9 is configured with 4-way mains monitoring wiring terminals, and the mains monitoring wiring terminals of the wireless interface module 9 are connected in parallel with the detected circuit in the normal lighting distribution box.

[0010] In the above technical solution, several emergency lighting controllers 1 are arranged in the building; each emergency lighting controller 1 is connected to several emergency lighting centralized power supplies 3; each emergency lighting centralized power supply 3 is connected to several fire emergency lamps 4.

[0011] In the above technical solution, the emergency lighting controller 1 adopts HY-C series products, with a built-in digital IO module and application software program; the emergency lighting centralized power supply 3 adopts HY-D series products, and its communication port is equipped with a lightning protection circuit, with a built-in digital IO module and application software program; the fire emergency luminaires 4 adopt the lighting lamps of HY-ZLJC series products and the marking lamps of HY-BLJC series products.

[0012] A wired remote fast linkage control method is applied to the above evacuation lighting system with a fast linkage control function. The control method is as follows:

[0013] After the wired remote interface module 5 monitors the power-off signal of the normal lighting distribution box through the mains monitoring terminal block, the wired remote interface module 5 uses the twisted pair of the existing system communication line to transmit the level signal to the wired linkage module 6. The wired linkage module 6 indirectly monitors the power-off signal of the normal lighting distribution box, and the wired linkage module 6 controls the emergency lighting centralized power supply 3 in a linkage manner.

[0014] A wireless fast linkage control method is applied to the above evacuation lighting system with a fast linkage control function. The control method is as follows:

[0015] After the wireless interface module 9 monitors the power-off signal of the normal lighting distribution box through the mains monitoring terminal block, it uses the wireless channel to transmit the wireless signal to the wireless linkage module 10. The wireless linkage module 10 indirectly monitors the power-off signal of the normal lighting distribution box, and the wireless linkage module 10 controls the emergency lighting centralized power supply 3 in a linkage manner. The emergency lighting centralized power supply 3 starts the fire emergency luminaires 4 in the corresponding fire area; the emergency start time is less than 0.25 s.

[0016] A light fast linkage control method is applied to the above evacuation lighting system with a fast linkage control function. The control method is as follows:

[0017] The illuminance value of the normal lighting in the environment is monitored by the light sensor 7. That is, when the ambient illuminance is lower than the set value, the light sensor 7 outputs a low-level signal to the light linkage module 8. The light linkage module 8 controls the emergency lighting centralized power supply 3 in a linkage manner. The emergency lighting centralized power supply 3 first starts the fire emergency luminaires 4 in the corresponding fire area; then, the emergency lighting centralized power supply 3 automatically judges whether a fire has occurred on site through the software program; when it is judged as a non-fire state, the emergency lighting centralized power supply 3 controls the fire emergency luminaires 4 to turn off within the specified time; the emergency start time is less than 0.25 s.

[0024] The control circuit of the wired remote interface module 5 further includes a DC relay J25 and its normally closed contacts J25-1, J25-2, and normally open contacts J25-3, J25-4;

[0025] The rated operating voltages of the AC relays J21, J22, J23, and J24 are AC220V and are respectively used for the status monitoring of 4 mains circuits;

[0026] The terminals L1, L2, L3, and L4 of the wired remote interface module 5 are connected to the live wires of the monitored circuits, and the terminal N is connected to the common neutral wire of the distribution box; the terminals A1 and B1 are connected in parallel with the communication terminal of the emergency lighting controller 1; the terminals A2 and B2 are connected in parallel with the terminals A3 and B3 of the wired linkage module 6 through long-distance twisted pairs; the terminals C1 and C2 are connected in parallel with the input interface of the digital IO inside the emergency lighting controller 1;

[0027] The AC relays J21, J22, J23, and J24 are respectively used for the status monitoring of 4 mains circuits, and the rated operating voltage is AC220V; the resistor R21 is used for charge release, the capacitor C21 is used for generating a monostable trigger signal, the resistor R22 is used for current limiting, and the diode D21 is used for freewheeling; the DC relay J25 is used for signal line conversion, and the rated operating voltage is DC24V;

[0029] (2) When the mains power supply fails, the wired remote interface module 5 has the following states: when any one of the mains power supplies monitored by terminal L1, terminal L2, terminal L3, and terminal L4 fails, it causes the corresponding AC relay to control the normally closed contact to conduct and the normally open contact to disconnect; the DC24V DC voltage triggers the DC relay J25 through the capacitor C21, and the normally open contact J25-1, the normally open contact J25-2, the normally closed contact J25-3, and the normally closed contact J25-4 are switched once in a monostable mode; first, the communication connection with the emergency lighting controller 1 is disconnected, and then the DC24V DC voltage is sent to the communication line after being limited by the resistor R22, and is transmitted to the input port of the wired linkage module 6 through the communication line, and returns to the normal communication state after a short period of time. The duration of the monostable mode conversion is changed by adjusting the capacitance value of the capacitor C21; in the case of mains power failure, the terminal block C1 and the terminal block C2 are locked in the open state, and the emergency lighting controller 1 determines that the mains power supply state is in the failure state.

[0030] The control circuit of the wired linkage module 6 of the above evacuation lighting system with a fast linkage control function is as follows:

[0031] The control circuit of the wired linkage module 6 includes a DC relay J26 and its normally open contact J26-1 and normally closed contact J26-2;

[0032] The control circuit of the wired linkage module 6 further includes a zener diode D22, a capacitor C22, a resistor R23, an optocoupler TP21, a resistor R24, a resistor R25, a triode T21, a triode T22, a DC relay J26, and a diode D23; the optocoupler TP21, the resistor R24, the resistor R25, the triode T21, and the triode T22 constitute the drive circuit of the DC relay J26;

[0035] (1) When the mains power is normal, the wired linkage module 6 is: the voltage value of the communication signal is less than the breakdown voltage value of the zener diode D22, the input current of the optocoupler TP21 is zero, the drive circuit of the DC relay J26 is in the cut-off state, the terminal D3 and the terminal D4 are in the short-circuit state, and the fire emergency luminaire 4 in the evacuation lighting system works in the non-emergency state;

[0036] (2) When the mains power fails, the wired linkage module 6 is: the DC24V DC pulse trigger voltage from the communication line causes the zener diode D22 to break down and conduct, the drive circuit of the DC relay J26 changes from the cut-off state to the saturation state, the DC relay J26 operates. Because the normally open contact J26-1 of the relay has a self-locking function, when the DC pulse trigger voltage disappears, the normally open contact J26-1 is locked in the conducting state and the normally closed contact J26-2 is locked in the off state. The terminal D3 and the terminal D4 are in the open-circuit state, and the linkage controls the emergency lighting centralized power supply 3 to start the fire emergency luminaire 4; the emergency start time of the wired linkage module 6 is not greater than 0.25S.

[0037] (3) When the failed mains power returns to normal, the emergency lighting controller 1 sends an instruction to exit the emergency state to the emergency lighting centralized power supply 3 through the communication line, and the emergency lighting centralized power supply 3 controls the fire emergency luminaire 4 to exit the emergency state; at the same time, the emergency lighting centralized power supply 3 disconnects the contacts in parallel of the terminal D1 and the terminal D2 to reset the DC relay J26 and exit the self-locking state, and then the emergency lighting centralized power supply 3 closes the contacts in parallel of the terminal D1 and the terminal D2 again.

[0046] (2) When the mains fails, for the wireless interface module 9: if any one of the mains circuits monitored by the terminal L31, terminal L32, terminal L33, and terminal L34 fails, it causes the normally closed contact of the corresponding AC relay to conduct, and the fast wireless transmitting device M31 immediately sends a jog control signal through the antenna.

[0047] The control circuit of the wireless linkage module 10 of the above evacuation lighting system with a fast linkage control function is as follows:

[0052] The control circuit of the light sensor 7 of the above - mentioned evacuation lighting system with fast linkage control function is as follows:

[0053] The control circuit of the light sensor 7 includes a resistor R11, a resistor R12, a resistor R13, a resistor R14, a resistor R15, a resistor R16, a photoresistor S11, an operational amplifier IC11, a linear voltage regulator IC12, a capacitor C11, a capacitor C12, a triode T11, and a diode D18;

[0054] The photoresistor S11, the operational amplifier IC11, the resistor R11, the resistor R12, the resistor R13, and the resistor R14 form a light measurement circuit; the linear voltage regulator IC12, the capacitor C11, and the capacitor C12 form a power supply with an output voltage of DC9V to supply power to the light measurement circuit; the function of the diode D18 is to reduce the falling - edge time of the output level signal; the resistor R15, the resistor R16, and the triode T11 form a level - shifting circuit.

[0055] (1) When the illuminance of the lighting environment is normal, the light sensor 7 is in the following state: the resistance value of the resistor S11 ≤ 12 kΩ, the output voltage of the light measurement circuit is low - level, which causes the triode T11 to operate in the cut - off state, the resistance value between the wiring terminals S1 and S2 is high - resistance state, the output voltage is high - level, and the voltage is DC20V - DC24V.

[0056] (2) When the illuminance of the lighting environment becomes low, the light sensor 7 is such that: the resistance value of resistor S11 > 32 kΩ, the output voltage of the light measurement circuit is at a high level, causing the triode T11 to operate in the saturation state. The resistance between terminal S1 and terminal S2 is in a low-resistance state, and the output voltage is the voltage value obtained by dividing the voltage between the resistor inside the light linkage module 8 and resistor R16, which is at a low level, and the voltage is DC12V - DC10V.

[0057] The control circuit of the light linkage module 8 of the above-mentioned evacuation lighting system with a fast linkage control function is as follows:

[0060] (1) When the illuminance of the lighting environment is normal, the light linkage module 8 is such that: the voltage between terminal S3 and terminal S4 is at a high level, the voltage is DC20V - DC24V, and the high level causes the zener diode D17 to break down and conduct, causing the triode T12 to operate in the saturation state. The normally open contact J11-1 of the relay J11 conducts, making the resistance between terminal D5 and terminal D6 in a short-circuit state;

[0061] (2) When the illuminance of the lighting environment becomes low, the light linkage module 8 is such that: the voltage between terminal S3 and terminal S4 is at a low level, the voltage is DC12V - DC10V, and the low level causes the zener diode D17 to not break down and conduct, causing the triode T12 to operate in the cut-off state. The relay J11 controls the normally open contact J11-1 to disconnect, making the resistance between terminal D5 and terminal D6 in an open-circuit state, and linkage-controls the emergency lighting centralized power supply 3 to quickly and emergently start the fire emergency lighting fixture 4.

[0062] The beneficial effects of the present invention are:

The wired linkage module 6 indirectly monitors the power-off signal of the normal lighting distribution box, and the wired linkage module 6 controls the emergency lighting centralized power supply 3 in a linkage manner. The emergency lighting centralized power supply 3 starts the fire emergency luminaires 4 in the corresponding fire area; the emergency start time is less than 0.25 s.

[0095] When the mains power fails, for the wired remote interface module 5: when any one of the mains power monitored by terminal L1, terminal L2, terminal L3, and terminal L4 fails, it causes the normally closed contact of the corresponding AC relay control to conduct and the normally open contact to disconnect; the DC24V DC voltage triggers the DC relay J25 through the capacitor C21, and the normally open contacts J25-1, J25-2, the normally closed contacts J25-3, and J25-4 are converted once in a monostable mode; first, the communication connection with the emergency lighting controller 1 is disconnected, and then the DC24V DC voltage is sent to the communication line after being limited by the resistor R22, and is transmitted to the input port of the wired linkage module 6 through the communication line, and returns to the normal communication state after a short time. The duration of the monostable mode conversion is changed by adjusting the value of the capacitance of the capacitor C21; in the case of mains power failure, the connection between terminal C1 and terminal C2 is locked in an open state, and the emergency lighting controller 1 determines that the mains power state is a failure state.

[0096] The circuit diagram of the wired linkage module 6 is as Figure 4 shown: The circuit of the wired linkage module 6 includes a DC relay J26 and its normally open contact J26-1 and normally closed contact J26-2;

[0099] The zener diode D22 is used for level shifting, the capacitor C22 is used for high-frequency pulse absorption, the resistor R23 is used for current limiting, and the diode D23 is used for freewheeling.

[0101] When the mains power fails, the wired linkage module 6 is such that: the DC24V DC pulse trigger voltage from the communication line causes the zener diode D22 to break down and conduct, the drive circuit of the DC relay J26 changes from the cut-off state to the saturation state, the DC relay J26 operates. Due to the self-locking function of the normally open contact J26-1 of the relay, when the DC pulse trigger voltage disappears, the normally open contact J26-1 locks in the conducting state and the normally closed contact J26-2 locks in the open state. The terminal block D3 and the terminal block D4 are in an open-circuit state, and the linkage controls the emergency lighting centralized power supply 3 to start the fire emergency luminaires 4; the emergency start time of the wired linkage module 6 is not greater than 0.25S.

[0102] When the failed mains power supply resumes normal operation, the emergency lighting controller 1 sends an instruction to exit the emergency state to the emergency lighting centralized power supply 3 through the communication line, and the emergency lighting centralized power supply 3 controls the fire emergency luminaires 4 to exit the emergency state; at the same time, the emergency lighting centralized power supply 3 disconnects the contact in parallel between the terminal block D1 and the terminal block D2 to reset the DC relay J26 (exit the self-locking state), and then the emergency lighting centralized power supply 3 closes the contact in parallel between the terminal block D1 and the terminal block D2.

[0103] The software subroutine flowchart for the emergency lighting controller to control the luminaires to exit the emergency state is as Figure 5 shown;

[0104] The system of this embodiment uses the wired remote interface module and the wired linkage module designed by the line multiplexing technology method to replace the remote lines for mains power monitoring, which not only reduces the construction difficulty but also saves the construction cost.

[0121] Embodiment 3

[0122] This embodiment is an evacuation lighting system with a fast linkage control function for light intensity monitoring.

[0123] This embodiment is particularly suitable for application in the subway section where the normal lighting is always on.

[0124] As Figure 9 shown, the system includes an emergency lighting controller 1, an emergency lighting centralized power supply 3, a fire emergency luminaire 4, a light sensor 7, and a light intensity linkage module 8;

[0125] The equipment distribution in this embodiment is as follows: (1) The emergency lighting controller 1 is installed in the fire control room; (2) The emergency lighting centralized power supply 3 is set in the weak current well 300 meters away from the normal lighting distribution box; (3) Several light sensors 7 are installed in the environment where the emergency lighting fixtures 4 are located; (4) The light linkage module 8 is set inside the chassis of the emergency lighting centralized power supply 3.

[0127] The control method is as follows:

[0128] The light sensor 7 is used to monitor the illuminance value of the normal lighting in the environment where it is located. That is, when the ambient light intensity is lower than the set value, the light sensor 7 outputs a low-level signal to the light linkage module 8. The light linkage module 8 controls the emergency lighting centralized power supply 3 in a linked manner. The emergency lighting centralized power supply 3 first starts the fire emergency lighting fixtures 4 in the corresponding fire area; Then, the emergency lighting centralized power supply 3 automatically judges whether a fire has occurred on site through a software program; When it is judged as a non-fire state, the emergency lighting centralized power supply 3 controls the fire emergency lighting fixtures 4 to turn off within a specified time; The emergency start-up time is less than 0.25 s.

[0129] The circuit diagram of the light sensor module in this embodiment is as Figure 10 shown: The light sensor 7 circuit includes a resistor R11, a resistor R12, a resistor R13, a resistor R14, a resistor R15, a resistor R16, a photoresistor S11, an operational amplifier IC11, a linear voltage regulator IC12, a capacitor C11, a capacitor C12, a triode T11, and a diode D18;

[0130] The photoresistor S11, the operational amplifier IC11, the resistor R11, the resistor R12, the resistor R13, and the resistor R14 form a light measurement circuit; The linear voltage regulator IC12, the capacitor C11, and the capacitor C12 form a power supply with an output voltage of DC9V to supply power to the light measurement circuit; The function of the diode D18 is to reduce the falling edge time of the output level signal; The resistor R15, the resistor R16, and the triode T11 form a level shift circuit.

[0131] When the illuminance of the lighting environment is normal, for the light sensor 7: the resistance value of the resistor S11 ≤ 12 kΩ, the output voltage of the light measurement circuit is low level, which causes the triode T11 to work in the cut-off state, and the state between the connection terminals S1 and S2 is a high resistance state, and the output voltage is high level, with a voltage of DC20V to DC24V.

[0132] When the illuminance of the lighting environment becomes low, the light sensor 7 has: the resistance value of resistor S11 > 32 kΩ, the output voltage of the light measurement circuit is high level, causing the triode T11 to operate in the saturation state, the resistance between terminal S1 and terminal S2 is in a low-resistance state, and the output voltage is the voltage value after voltage division between the resistor inside the light linkage module 8 and resistor R16, which is low level, and the voltage is DC12V to DC10V.

[0135] When the illuminance of the lighting environment is normal, the light linkage module 8 has: the voltage between terminal S3 and terminal S4 is high level, the voltage is DC20V to DC24V, the high level causes the zener diode D17 to break down and conduct, causing the triode T12 to operate in the saturation state, and the normally open contact J11-1 of the relay J11 conducts, making the resistance between terminal D5 and terminal D6 in a short-circuit state;

[0136] When the illuminance of the lighting environment becomes low, the light linkage module 8 has: the voltage between terminal S3 and terminal S4 is low level, the voltage is DC12V to DC10V, the low level causes the zener diode D17 not to break down and conduct, causing the triode T12 to operate in the cut-off state, the relay J11 controls the normally open contact J11-1 to disconnect, making the resistance between terminal D5 and terminal D6 in an open-circuit state, and linkage-controls the emergency lighting centralized power supply 3 to quickly and emergently start the fire emergency lighting fixture 4.

[0137] The software subroutine flowchart for the emergency lighting centralized power supply 3 to control the lighting fixture to exit the emergency state is as Figure 12 shown;

[0138] The system of this embodiment uses a light sensor module 7 and a light linkage module 8 designed by a light monitoring technology method to replace the remote line for mains power monitoring, which not only reduces the construction difficulty but also saves the construction cost. The emergency start-up time can be less than 0.25S.
