[0029] Exemplary controller

[0030] Figure 1 This is a schematic diagram of the structure of an integrated emergency power supply vehicle controller according to a preferred embodiment of the present invention. Figure 1 As shown, the emergency power vehicle integrated controller 100 according to this preferred embodiment includes:

[0031] The signal acquisition module 101 is connected to the emergency power vehicle generator set, the busbar and the mains power input terminal, and the load output terminal respectively, and is used to synchronously acquire the generator set voltage and current, the busbar voltage, the mains voltage and the mains current, and the load current.

[0032] Preferably, the signal acquisition module 101 includes:

[0033] The voltage acquisition submodule is equipped with three independent voltage signal input terminals that are respectively connected to the voltage of the emergency power vehicle generator set, the bus voltage, and the mains voltage. It is used to acquire the voltage amplitude, frequency, and phase of the emergency power vehicle generator set, the bus, and the mains voltage in real time.

[0034] The current acquisition submodule is equipped with three sets of current signal input terminals that are respectively connected to the emergency power vehicle generator current, the mains current, and the load current. The current signal input terminals are used to connect the secondary coil of an external current transformer to acquire the corresponding current parameters in real time.

[0035] In this preferred embodiment, separate terminals for acquiring the voltage of the generator set, busbar, and mains power, as well as terminals for acquiring the current of the generator set, mains power, and load power, are specially set up. This provides a hardware foundation for the central processing unit to achieve accurate grid synchronization, power calculation, and system protection, which is a prerequisite for realizing the integrated function of the controller.

[0036] The digital input module 102 is used to detect the position status information of the switching devices of the emergency power vehicle generator set, mains power and load, as well as to receive external grid connection mode commands.

[0037] Preferably, the switch input module 102 includes:

[0038] The first input submodule is equipped with multiple input terminals for detecting the circuit breaker closing status, disconnecting switch and grounding switch status of the emergency power vehicle generator set, mains power and load respectively;

[0039] The second input submodule is equipped with grid-connected mode input terminals, which are used to receive external grid-connected mode commands and transmit them to the central processing unit.

[0040] Preferably, the switch input module 102 further includes a backup input submodule, which is provided with multiple backup input terminals for function expansion or receiving other custom signals.

[0041] In this preferred embodiment, the signals collected by the digital input module not only include the basic circuit breaker closed position signal, but also integrate the status signals of the isolating switch and grounding switch for safety interlocking (such as GCB isolating switch closed, GCB grounding switch closed, etc.). This allows a single controller to complete complex safety logic judgments without the need for external relay combination logic.

[0042] The sensor interface module 103 connects the engine body sensor and speed sensor interface of the emergency power vehicle generator set to collect the corresponding sensor signals.

[0043] Preferably, the sensor interface module 103 includes:

[0044] The first interface submodule is used to connect to the engine body sensor of the emergency power vehicle generator set. It is configured to receive voltage, current or resistance signals, and the default configuration is to receive resistance signals. It is used to collect engine-related parameters, including at least one of temperature, oil level and oil pressure.

[0045] The second interface submodule is used to directly connect to the magnetoelectric speed sensor of the emergency power vehicle generator set engine to receive its speed pulse signal and transmit it to the central processing unit for grid connection control.

[0046] The communication interface module 104 is used to communicate privately with the engine electronic control unit of the generator set in the emergency power vehicle, directly obtain engine operating parameter data, and exchange parallel communication status and parallel communication data when two or more emergency power vehicles are working in parallel.

[0047] Preferably, the communication interface module 104 includes:

[0048] The first CAN bus interface is used for private communication with the engine electronic control unit to directly obtain the deep operating parameters of the emergency power vehicle generator set engine, and send the device control command control interface module of the central processing unit to achieve native integrated control of the engine.

[0049] The second CAN bus interface serves as a parallel communication bus. When two or more emergency power vehicles are operating in parallel, the integrated controllers on each emergency power vehicle are directly interconnected to exchange parallel communication status and data, thereby realizing the parallel logic.

[0050] In this preferred embodiment, grid-connected control of a single emergency power vehicle can be achieved by privately communicating with the engine electronic control unit via the first CAN bus interface on each emergency power vehicle. Parallel communication is then conducted via a reserved second CAN bus interface, allowing multiple devices to form a peer-to-peer network. Parallel operation can be completed solely through communication between controllers, resulting in extremely flexible system configuration and significantly reduced costs.

[0051] Preferably, the communication interface module 104 further includes an RS485 communication interface for networking communication with a host computer, touch screen or other smart devices to achieve remote monitoring and data transmission.

[0052] The preferred embodiment of this invention uses a fully open communication protocol platform for data communication, enabling open protocol and control point information, building a standardized and unified emergency power supply vehicle product, improving the level of intelligence, and achieving interconnection and interoperability of power supply products.

[0053] Furthermore, the communication addresses of emergency power vehicle controllers in the prior art range from 1 to 32 units. Because two controllers are required, the maximum number of units that can be connected in parallel is 16. However, with the integrated controller of the preferred embodiment of the present invention, the number of units that can be connected in parallel can be doubled under the same communication scheme, that is, 32 units can be connected in parallel.

[0054] The central processing unit 105 is used to perform corresponding protection logic calculations and parallel communication data calculations on the data and instructions input from the signal acquisition module, the switch input module, the sensor interface module and the communication interface module, and to issue at least one of the following based on the calculation results: switch control instructions, equipment control instructions and status indication instructions.

[0055] The control interface module 106 is directly connected to the engine speed regulator and generator exciter of the emergency power vehicle generator set, and is used to output control commands for the equipment to achieve closed-loop control of the speed and voltage of at least one emergency power vehicle generator set.

[0056] In this preferred embodiment, a dedicated output interface for regulating the engine speed of the emergency power vehicle generator set and the voltage regulation of the generator excitation high voltage unit is integrated. This allows the instructions output by the central processing unit to directly control the core parameters of the generator in a closed loop, thereby further consolidating its "integrated" status and replacing the hardware design of independent speed governor and voltage regulator interface modules that may be required in existing systems.

[0057] The switch output module 107 is used to output the switch control command to drive and control at least one emergency power vehicle generator set, the switching on and off of the mains power and load, start the engine, and output the status indication command to drive the alarm to issue an alarm signal and / or drive the engine to run at rated speed and display the operating status.

[0058] Preferably, the switch output module 107 includes:

[0059] The first output submodule is connected to the engine of the emergency power vehicle generator set and is used to start and stop the engine and oil pump according to the switch control command.

[0060] The second output submodule is used to output the switch control command to control the opening and closing of the circuit breakers of the emergency power vehicle generator set engine, mains power and load;

[0061] The third output submodule is used to output the status indication command to drive the alarm to issue an alarm signal and / or drive the engine to run at the rated speed and display the operating status.

[0062] The integrated emergency power vehicle controller described in this preferred embodiment integrates all necessary signal acquisition, logic processing, and execution drive functions for unit control, parallel operation control, and grid connection control into a single controller through its hardware architecture design. The completeness and specialization of its hardware interfaces allow a single controller to replace the existing combination of "unit controller + parallel operation and grid connection controller," achieving true integrated control. Using the controller constructed from a two-in-one general-purpose hardware platform described in this preferred embodiment, multiple controllers can be replaced to achieve the same functionality. One emergency power vehicle can successfully complete grid connection, and two or more emergency power vehicles can complete parallel operation through communication with the controller installed in the vehicle, eliminating the need for a separate parallel operation and grid connection controller. This greatly simplifies external wiring and operation, fundamentally reducing the probability of failures caused by loose interfaces and equipment compatibility issues. It achieves significant improvements in system simplification and reliability, and only requires maintenance of one controller per emergency power vehicle, making debugging, fault diagnosis, and replacement much simpler and faster.

[0063] Exemplary method

[0064] Figure 2 This is a flowchart illustrating a method for grid-connected and parallel-operated control of an emergency power supply vehicle according to a preferred embodiment of the present invention. Figure 2 As shown, the method for grid-connected and parallel-operated control of emergency power vehicles according to this preferred embodiment begins from step 201.

[0065] In step 201, the signal acquisition module synchronously acquires the unit voltage and unit current, bus voltage, mains voltage and mains current, and load current;

[0066] In step 202, the digital input module synchronously detects and controls the position status information of the switching devices of the emergency power vehicle generator set, the mains power and the load, and receives external grid connection mode commands;

[0067] In step 203, the sensor interface module acquires sensor signals from the engine body sensor and speed sensor of the emergency power vehicle generator set;

[0068] In step 204, the communication interface module establishes private communication with the engine electronic control unit of the emergency power vehicle generator set to directly obtain engine operating parameter data;

[0069] In step 205, the central processing unit performs corresponding protection logic calculations and parallel communication data calculations on the data and instructions input from the signal acquisition module, the switch input module, the sensor interface module, and the communication interface module, and issues at least one of the following based on the calculation results: switch control instructions, equipment control instructions, and status indication instructions.

[0070] In step 206, the control interface module, which is directly connected to the engine speed regulator and generator exciter of the emergency power vehicle generator set, outputs the equipment control command to achieve closed-loop control of the speed and voltage of at least one emergency power vehicle generator set.

[0071] In step 207, the switch output module outputs the switch control command to drive and control at least one emergency power vehicle generator set, the switching on and off of the mains power and load, start the engine, and output the status indication command to drive the alarm to issue an alarm signal and / or drive the engine to run at rated speed and display the operating status.

[0072] The method described in this preferred embodiment employs an integrated controller for grid-connected and parallel operation control of emergency power vehicles. When an external grid-connection mode command is received, data is collected and transmitted to the central processing unit through a signal acquisition module, a switch input module, a sensor interface module, and a communication interface module. The central processing unit performs corresponding protection logic calculations and parallel operation communication data calculations based on the input data, and issues at least one of a switch control command, an equipment control command, and a status indication command based on the calculation results. The control interface module and the switch input module then perform corresponding operations based on the output commands to complete the grid connection of a single emergency power vehicle and the parallel operation of two or more emergency power vehicles. This effectively solves the technical problem that existing emergency power vehicles require the simultaneous operation of two controllers when paralleling or connecting to the grid, which is cumbersome and prone to failure due to human error, resulting in the risk of power loss to important loads and significant economic losses.
