Description

Technical Field

[0001] This application relates to the field of power supply and distribution technology for fire protection systems, and in particular to an intelligent power distribution system. Background Technology

[0002] With the rapid development of the fire truck industry, in order to meet the growing demand for emergency rescue equipment for large-scale disaster relief, fire trucks with various functions are emerging one after another. Tank fire trucks, as a highly representative fire-fighting equipment, are widely used in emergency rescue scenarios.

[0003] Existing fire trucks typically use distribution cabinets to supply power to different fire-fighting systems. Traditional distribution cabinets can meet basic usage needs, but when the number of fire-fighting systems with higher power or load current requirements increases, more relays are needed in the distribution cabinet to achieve higher power or load current output distribution. This increases the complexity of the power distribution output connection lines and the cost of power distribution. Utility Model Content

[0004] In view of this, the purpose of this application is to provide at least one intelligent power distribution system that uses digital power distribution modules to replace traditional power distribution cabinets for power distribution to fire-fighting operation power systems, thereby avoiding the use of relays, reducing the complexity of power distribution output lines, and reducing power distribution costs.

[0005] This application mainly includes the following aspects:

[0006] In a first aspect, embodiments of this application provide an intelligent power distribution system, which includes a digital power distribution module, a fire-fighting operation power system, and an upper-mounted display. The digital power distribution module provides multiple power distribution output interfaces with different power distribution capabilities. The fire-fighting operation power system is connected to multiple target power distribution output interfaces corresponding to its required power distribution capabilities. The upper-mounted display is connected to both the digital power distribution module and the fire-fighting operation power system.

[0007] In one possible implementation, the digital power distribution module includes a digital power distribution control unit connected to a multi-channel power distribution output interface.

[0008] In one possible implementation, the fire-fighting operation power system includes multiple fire-fighting operation systems, each of which is connected to a power distribution output interface that meets the power distribution requirements of its corresponding circuit.

The fire-fighting operation power system is connected to multiple target power distribution output interfaces corresponding to its required power distribution capabilities.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] With the rapid development of the fire truck industry, in order to meet the growing demand for emergency rescue equipment for large-scale disaster relief, fire trucks with various functions are emerging one after another. Tank fire trucks, as a highly representative fire-fighting equipment, are widely used in emergency rescue scenarios.

[0024] Please see Figure 1 , Figure 1 A schematic diagram of a prior art electrical system for use on a fire truck is shown. Figure 1 As shown, the existing fire truck's power supply system includes a vehicle power supply 11, a power distribution cabinet 12, and a fire operation power supply system 13. The fire operation power supply system 13 includes multiple fire operation systems 130. The power distribution cabinet 12 is equipped with multiple power distribution outputs. Each power distribution output includes at least power distribution devices such as fuses, relays, and terminals. Each power distribution output achieves different load current or load power outputs through its corresponding connected power distribution devices.

[0025] Furthermore, the vehicle power supply 11 (battery) supplies power to the distribution cabinet 12. Through the power distribution devices corresponding to different power distribution outputs in the distribution cabinet 12, the vehicle power supply 11 supplies multiple fire-fighting operation systems 130. The multiple fire-fighting operation systems 130 include, but are not limited to, lighting systems, water systems, high-power load systems, superstructure control systems, power converter systems, and temperature control systems.

[0026] The existing power supply system on the fire truck can meet basic usage requirements. However, when the fire operation system 130 has a large power requirement or a large load current requirement (for example, for a high-power load system), the corresponding power output in the distribution cabinet 12 needs to use more relays to achieve a large power or large load current output through circuit logic to power the fire operation system 130 with a large power requirement that is subsequently connected. It can be seen that the traditional power supply form of the distribution cabinet increases the complexity of the power output connection line and increases the power distribution cost.

[0027] Based on this, this application provides an intelligent power distribution system that uses digital power distribution modules to replace traditional distribution cabinets for power distribution to the fire-fighting operation power system, avoiding the use of relays, reducing the complexity of power distribution output lines, and reducing power distribution costs, as detailed below:

[0028] Please see Figure 2 , Figure 2 A schematic diagram of the structure of an intelligent power distribution system provided in an embodiment of this application is shown. Figure 2 As shown in the embodiment of this application, the intelligent power distribution system is applied to a fire truck. The intelligent power distribution system specifically includes a vehicle power supply 11, a digital power distribution module 14, and a fire operation power system 13. The fire operation power system 13 includes multiple fire operation systems 130. The digital power distribution module 14 provides multiple power distribution output interfaces with different power distribution capabilities.

[0029] Specifically, the power distribution capacity of the power distribution output channel is reflected by the load current output capacity or the load power output capacity.

[0030] The vehicle power supply 11 is connected to the digital power distribution module 14 to become the power supply for the digital power distribution module 14, and the fire-fighting operation power system is connected to the multi-target power distribution output interface corresponding to its required power distribution capacity.

[0031] In one specific embodiment, the digital power distribution module 14 can be an SDCR100-TR model. The digital power distribution module uses professional automotive-grade components and integrates a digital power distribution control unit (not shown in the figure). This control unit connects to multiple power distribution output interfaces. The control unit pre-integrates control logic corresponding to the outputs of each power distribution output interface. After connecting to different power distribution output interfaces, a power distribution output channel is formed for each interface. For power distribution output interfaces requiring high power or high current output, a high-power output chip is integrated between the output interface and the digital power distribution control unit. This high-power or high-current output is achieved through the high-power output chip. Compared to traditional power distribution cabinets that use relays for high-power output, the high-power output chip can directly drive high-power equipment (such as motors and lights) in the subsequent fire-fighting system without the need for relays. It can directly distribute power according to the output logic integrated in the digital power distribution control unit, resulting in stronger controllability, higher reliability, and longer lifespan.

[0032] In one specific embodiment, Table 1 shows a power distribution output channel parameter table corresponding to a digital power distribution module provided in the embodiments of this application.

[0033] Table 1:

[0034]

[0035] As shown in Table 1, the digital power distribution module provides a total of 42 power distribution output channels, including 1 160A channel (power distribution output channel supporting 160A load current output), 1 120A channel, 2 40A channels, 1 30A channel, 8 20A channels, 7 10A channels, 6 5A channels, 12 3A channels, and 4 1A channels.

[0036] In a preferred embodiment, for each fire operation system 130, the fire operation system 130 is connected to the power distribution output interface corresponding to the power distribution output channel that meets the power distribution requirements of its corresponding circuit. For example, if the power distribution requirement of a certain fire operation system is 10A, then according to Table 1, the fire operation system needs to be connected to the power distribution output interface corresponding to a 10A channel.

[0037] In a preferred embodiment, the multiple fire-fighting operation systems include a main control system and multiple slave control systems. The main control system is connected to the multiple slave control systems respectively. Specifically, the main control system is an upper-level control system, and the slave control systems include, but are not limited to, at least one of the following: lighting system, water system, high-power load system, power converter system, and temperature control system.

[0038] Furthermore, the electrical equipment in the upper structure control system includes, but is not limited to, at least one of the following: controllers and remote controllers; the electrical equipment in the lighting system includes, but is not limited to, at least one of the following: warning lights, marker lights, and headlights; the electrical equipment in the water system includes, but is not limited to, at least one of the following: valves, water control-related sensors, and electric actuators; the electrical equipment in the high-power load system includes, but is not limited to, at least one of the following: winches, lifting lights, and electric vacuum pumps; the electrical equipment in the power converter system includes, but is not limited to, at least one of the following: inverters and power step-down modules; and the electrical equipment in the temperature control system includes, but is not limited to, at least one of the following: heating-related equipment and cooling-related equipment.

[0039] In a preferred embodiment, the digital power distribution module provided in this application also integrates a monitoring unit. The monitoring unit is connected to multiple power distribution output interfaces and can monitor the relevant status monitoring data (including but not limited to load status, actual power consumption current, and actual system operating temperature) of all fire protection systems connected to the power distribution output interfaces in real time. The monitoring unit has a protection mechanism corresponding to each power distribution output interface. The protection mechanism includes, but is not limited to, at least one of the following: overcurrent protection (triggered by the overcurrent protection threshold integrated in the monitoring unit), short circuit protection (triggered by the short circuit protection threshold integrated in the monitoring unit), and overtemperature protection (triggered by the temperature protection threshold integrated in the monitoring unit) and current protection threshold triggering.

[0040] In a preferred embodiment, the intelligent power distribution system further includes an upper-mounted display 15, which is connected to a monitoring unit within the digital power distribution module 14 via a first designated communication channel.

[0041] Preferably, the digital power distribution module 14 also provides a first communication interface, and the upper display 15 provides a second communication interface. Preferably, the first and second communication interfaces can be CAN communication interfaces, and the first designated communication channel is a communication channel formed by connecting the first and second communication interfaces.

[0042] Modern fire trucks, due to their multi-functional operation requirements including firefighting and rescue, are equipped with a wide variety and large quantity of equipment. This results in limited space for the installation of electrical distribution cabinets, which are often installed in spaces that are not suitable for operation and maintenance, causing inconvenience in maintenance. In the event of electrical overload, short circuit, or replacement of damaged relays, maintenance requires further investigation in conjunction with electrical drawings, making it impossible to intuitively determine the specific fault.

[0043] Furthermore, when a fault occurs in the intelligent power distribution system, such as a short circuit or a significant overload on the equipment, troubleshooting can only be carried out after the fuse blows and the problem is discovered by human intervention. This results in a lack of timely problem detection in the existing power distribution system.

[0044] Therefore, in the technical solution provided in this application, the upper-mounted display 15 collects data from the monitoring unit in the digital power distribution module 14 through the first designated communication channel formed between the first communication interface and the second communication interface. It monitors the timing circuit data such as the load current of the circuits in each fire operation system connected to the digital power distribution module in real time. With the protection mechanism integrated inside the monitoring unit, when a fault occurs in the fire operation system, the display will promptly show the corresponding fault prompt of the current faulty power supply circuit and issue an audible and visual alarm. The fault point can be determined without the operator referring to the electrical drawings, and there is no need to replace the relay, which greatly facilitates the user.

[0045] The monitoring module within the digital power distribution module provided in this application integrates a protection mechanism based on protection thresholds, eliminating the need for fuses in traditional power distribution cabinets. It automatically cuts off power supply after an overload protection short circuit occurs in the electrical equipment within the subsequently connected fire protection system, and has the ability to automatically restore power supply after the fault is cleared, thus avoiding the need for fuse removal.

[0046] In a preferred embodiment, the upper display 15 is also connected to the main control system in the fire-fighting operation power system through a second designated communication channel. The upper display 15 provides a third communication interface, the main control system provides a fourth communication interface, and the second designated communication channel is a communication channel formed by connecting the third and fourth communication interfaces.

[0047] Specifically, the third and fourth communication interfaces can be CAN communication interfaces. In this application, in addition to serving as the upper control system of the main control system, it is responsible for issuing corresponding control commands to multiple slave control systems such as the lighting system, water system, high-power load system, power converter system and temperature control system, and for collecting relevant fault information of the slave control systems.

[0048] The main control system sends the collected fault information of itself and the slave control system to the upper-mount display 15 through the second designated communication channel. The upper-mount display 15 displays the corresponding fault information and provides fault warnings.

[0049] In this application, the power supply terminal of the upper display 15 is also connected to the power distribution output interface (not shown in the figure) provided by the digital power distribution module to meet the power requirements of the application.

[0050] Therefore, this application uses a digital power distribution module to replace the traditional power distribution cabinet for power supply and distribution to the fire operation power system. With the help of the display, abnormal power distribution (through the monitoring unit) and faults occurring in each fire operation system can be displayed intuitively.

[0051] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
