Description

Technical Field

[0001] This utility model relates to the field of fire emergency evacuation technology, and in particular to an intelligent evacuation two-electricity-one-door monitoring integrated system. Background Technology

[0002] Traditional intelligent evacuation systems, along with electrical fire monitoring, fire power supply monitoring, and fire door monitoring, constitute four distinct systems in the fire emergency field. The electrical fire monitoring, fire power supply monitoring, and fire door monitoring systems, commonly known as the "two-electricity-one-door" system, are used to monitor the power supply and evacuation systems in public places. In practical applications, intelligent evacuation systems and the "two-electricity-one-door" system are typically wired separately and controlled in a decentralized manner. For example, existing "two-electricity-one-door" systems are basically composed of a host and device nodes. Communication between the host and each device node uses a two-bus communication method. Therefore, each system uses separate wiring, and there is no shared information channel between systems. This results in high wiring costs and hinders information exchange between systems, impeding overall system integration. Integrating multiple systems together would not only reduce redundant hardware but also minimize wiring costs and maintenance expenses caused by complex wiring. Furthermore, combining multiple systems facilitates information sharing, improves emergency evacuation efficiency, and effectively enhances future system scalability. Therefore, it is necessary to make further improvements to the existing technology. Utility Model Content

Detailed Implementation

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] like Figure 1-2As shown, the intelligent evacuation two-electricity-one-door monitoring integrated system includes a hub 1, an electrical fire monitoring host 2, a fire protection equipment power status monitoring host 3, a fire door monitoring host 4, an intelligent evacuation host 5, an emergency evacuation lighting power supply 6, a fire monitoring detector 7, a door magnetic switch 8, a fire door monitoring module 9, a voltage / current signal sensor 10, and a lamp 11. The fire monitoring detector 7, the door magnetic switch 8, the fire door monitoring module 9, the voltage / current signal sensor 10, and the lamp 11 are all communicatively connected to the emergency evacuation lighting power supply 6. The hub 1 is communicatively connected to the electrical fire monitoring host 2, the fire protection equipment power status monitoring host 3, the fire door monitoring host 4, the intelligent evacuation host 5, and the emergency evacuation lighting power supply 6. Understandably, the electrical fire monitoring host 2 can be a general electrical fire monitoring host, the fire protection equipment power status monitoring host 3 can be a general fire protection power supply monitoring host, the fire door monitoring host 4 can be a general fire door monitoring host, the intelligent evacuation host 5 can be a general intelligent evacuation host, the emergency evacuation lighting power supply 6 can be a general emergency evacuation lighting power supply, the fire monitoring detector 7 can be a general fire monitoring detector, the door magnetic switch 8 can be a general door magnetic switch light, the fire door monitoring module 9 can be a general fire door monitoring module, the voltage / current signal sensor 10 can be a general voltage / current signal sensor, and the lamp 11 can be a general fire emergency lamp. The existing intelligent evacuation system consists of the aforementioned host, power supply (i.e., emergency evacuation lighting power supply 6), and lighting nodes. The power supply and lighting nodes also communicate via a two-bus method. Therefore, the physical layer transmission methods of the two systems are consistent, and the two systems can be unified through a unified application layer protocol. In order to enable communication between various types of host and terminal device nodes, a hub device needs to be added. The information uploaded and sent by each host device is forwarded through the hub. The hub is located between the host and the power supply. The device nodes in the original two-power-one-door system are all connected to the power supply, and the original communication method remains unchanged. The power supply then communicates with the host of the two-power-one-door system and the host of the intelligent evacuation system through the hub. Through this modification, multiple systems share a single bus, thereby achieving multi-system collaboration at minimal cost.

[0019] Understandably, in practical applications, each host computer sends the address signals of the lighting fixtures, door sensors, and other sensors to the power supply via configuration control signals. The power supply then polls each device node (i.e., the door sensors for monitoring lighting fixtures and fire doors in the intelligent evacuation system, the sensors for monitoring power supply to fire-fighting equipment, and the sensors in the electrical fire monitoring system) using polling signals. The power supply continuously polls the connected lighting fixtures, door sensors, and other sensors according to the node table downloaded to the devices, using status query signals. These signals carry the address information of each node. When each device node receives a signal matching its own address, it responds to the power supply with its own status, including whether the lighting fixture is normal or faulty, the current door sensor switch status, and the sensor values. The power supply saves the corresponding response signal until it receives a new signal in the next poll. Each host computer also continuously polls the power supply based on the saved node signals to obtain the node signals collected by the power supply. The hub does not process the signals received from the hosts; it only forwards them. As a critical relay system, a hub must possess the following three main characteristics: 1. Because RS485 is a half-duplex mode, and the hub receives polling signals from multiple hosts simultaneously, it must have a sufficiently large buffer to store the received information and queue the signals; 2. For multi-host and multi-power supply systems, to ensure system robustness, in addition to the timeout mechanism on the hosts, the hub must also have a timeout handling mechanism; 3. Since the hub receives not only ordinary polling signals but also other configuration signals, it must have a message priority processing mechanism that can determine whether to adjust the processing priority based on different message types.

[0020] Understandably, the hub communicates with each host and with the power supply using the traditional RS485 method, which has advantages such as long communication distance, stable and reliable transmission, and variable data packet frame length. The power supply and device nodes are connected using the traditional two-bus method, which has advantages such as simple wiring, long communication distance, and stable data transmission. Each host is connected to the hub through multiple independent RS485 buses. The hub does not parse the protocol data, but only transmits it to the power supply, which then parses the protocol data.

[0021] Specifically, the hub 1 includes an MCU module, a charge / discharge control circuit, an input voltage measurement circuit, a first 485 communication circuit, a second 485 communication circuit, a third 485 communication circuit, a fourth 485 communication circuit, and a 232 communication interface circuit. The charge / discharge control circuit, the input voltage measurement circuit, the first 485 communication circuit, the second 485 communication circuit, the third 485 communication circuit, the fourth 485 communication circuit, and the 232 communication interface circuit are all electrically connected to the MCU module. The first 485 communication circuit, the second 485 communication circuit, the third 485 communication circuit, the fourth 485 communication circuit, and the 232 communication interface circuit are respectively communicatively connected to the electrical fire monitoring host, the fire protection equipment power status monitoring host, the fire door monitoring host, the emergency evacuation lighting power supply, and the intelligent evacuation host. Understandably, the first 485 communication circuit includes a 485 communication chip U51 and its peripheral circuits; the second 485 communication circuit includes a 485 communication chip U52 and its peripheral circuits; the third 485 communication circuit includes a 485 communication chip U53 and its peripheral circuits; and the fourth 485 communication circuit includes a 485 communication chip U14 and its peripheral circuits. All four 485 communication chips (U51, U52, U53, and U14) utilize the CA-IS2092W chip. The 232 communication interface circuit includes a 232 communication interface P2, which can be used to connect the hub 1 to the intelligent evacuation host 5.

[0022] Specifically, the MCU module includes a microcontroller chip U41, a crystal oscillator Y4, a resistor R202, a reset interface J11, resistors R265 and R266, all of which are connected to the microcontroller chip U41. It is understood that the microcontroller chip U41 is an AT32F403AVCT7 chip.

[0023] Specifically, the charge / discharge control circuit includes an electrical coupler U49, a transistor Q4, a diode D102, a transistor Q5, a transistor Q6, a transistor Q9, an inductor L2, a power interface P7, operational amplifiers U24B and U24A, a reset button S2, and an interface P81. The electrical coupler U49 is connected to the power interface P7, the diode D102, the microcontroller chip U41, and the transistor Q9. The transistor Q5 is connected to the diode D102, the transistor Q4, the transistor Q9, and the transistor Q6. The inductor L2 is connected to the transistor Q4. Operational amplifiers U24B and U24A, reset button S2, and interface P81 are all connected to the microcontroller chip U41. The input voltage measurement circuit includes resistors R69, R71, capacitors C112, R76, R77, R79, and C108. Resistors R69 and R76 are connected to the electrical coupler U49, and resistors R77 and R79 are connected to resistor R76. Resistors R69, R71, C112, R77, and C108 are all connected to the microcontroller chip U41. It is understood that the charge / discharge control circuit is used to control the charging and discharging of the battery, and the input voltage measurement circuit is used to measure the input voltage.

[0024] Understandably, this utility model is reasonably designed and uniquely constructed. By adding a hub 1, multiple systems are integrated into a single unit, which not only reduces redundant hardware equipment but also minimizes cabling costs and maintenance expenses caused by complex cabling. Furthermore, combining multiple systems facilitates information sharing, improves emergency evacuation efficiency, effectively enhances the future scalability of the system, and enables resource sharing, intelligent linkage, and data fusion, significantly improving safety, efficiency, and economic benefits.
