A vibration-damping pad 4 is provided between the frame 1 and the fixing seats 5, which is effectively connected to the body 6, and can reduce the vibration of the body 6 transmitted to the electrical components, thereby protecting the stability of the internal performance components.

[0035] In some embodiments, the panel protective cover 3 is made of a transparent acrylic protective cover to prevent accidental collision during vehicle driving or operation, thereby improving the safety of vehicle electrical appliances.

[0036] In this embodiment, if Figure 1As shown, the control panel 2 is equipped with a dual-energy switching switch 202, a parameter display table 201 (i.e., a voltage, current, and frequency table), a non-critical power main switch QF3, and a critical power main switch QF2. Specifically, the dual-energy switching switch 202 is used to switch between the mains power supply 205 and the UPS power supply 206 (uninterruptible power supply). The dual-energy switching switch 202 includes a UPS terminal and a mains terminal. The output of the UPS terminal is connected to the input of the critical power main switch 208. The output of the critical power main switch 208 is respectively connected to the inputs of the critical socket power supply 215, the display power supply 216, the cabinet power supply 217, the interior lighting power supply 218, and the critical backup power supply 219. The output of the mains terminal is connected to the input of the non-critical power main switch 207. The output of the non-critical power main switch 207 is respectively connected to the inputs of the air conditioning power supply 210, the non-critical socket power supply 211, the cabin socket power supply 212, the roof equipment power supply 213, and the non-critical backup power supply 214.

In other words, the mains power supply 205 is divided into a mains power supply portion and a UPS power supply portion through the control panel, and the mains power supply portion is further divided into a power supply for multiple non-critical devices, and the UPS power supply portion is divided into a power supply for multiple critical devices. The power supply of multiple critical devices is controlled by the key power main switch 208, and the power supply of multiple non-critical devices is controlled by the non-critical power main switch, thereby achieving flexible and efficient distribution of AC power.

[0039] The current input terminal of the parameter display meter 201 is connected to the output terminal of the mains power supply 205, and the voltage input terminal is connected to the output terminal of the mains power supply 205, and is used to display parameters such as the voltage, current, and power of the mains power supply 205. The parameter display meter 201 is connected to the output terminal of the display power supply 216, and the display power supply 216 supplies power to the parameter display meter 201.

[0040] like Figure 1As shown, guide rail fixing seats 203 are fixedly provided on both sides of the control panel 2, and an air switch guide rail 204 is fixedly provided between the guide rail fixing seats 203 on both sides. The air switch guide rail 204 is used to fix the air switch neatly and orderly for easy maintenance and management. The air switch guide rail 204 is divided into a non-critical power supply part and a critical power supply part. The air switch guide rail 204 of the non-critical power supply part is fixedly provided with a non-critical power main switch 207 (QF3) and a plurality of corresponding sub-air switches QF4. The air switch guide rail 204 of the critical power supply part is fixedly provided with a critical power main switch 208 (QF2) and a plurality of corresponding sub-air switches QF4 for realizing the on-off and overload protection of the circuit. The key power supply main switch QF2 is used to perform overall control of the key power supply, that is, to control the on and off of all key power supply branches. The sub-air switch QF4 set on the key power supply branch is used to realize the on and off control of a single key power supply; the non-critical power supply main switch QF3 is used to perform overall control of the non-critical power supply, that is, to control the on and off of all non-critical power supply branches. The sub-air switch QF4 set on the non-critical power supply branch is used to realize the on and off control of a single non-critical unit.

[0041] Further, such as Figure 2 As shown, Figure 1 Correspondingly, a key power main switch 208 (QF2) is set on the main circuit between the output end of the dual energy switching switch 202 and each key power supply, and a sub-air switch QF4 is respectively set between the main circuit and the input end of each key power supply (that is, on each key power supply branch); a non-key power main switch 207 (QF3) is set on the output end of the AC power supply 205 and the main circuit of each non-key power supply, and a sub-air switch QF4 is respectively set between the main circuit and the input end of each non-key power supply (that is, on each non-key power supply branch) to realize the on-off and protection of the circuit.

[0042] In this power control system, the critical power main switch 208 (QF2) and the non-critical power main switch 207 (QF3) control the UPS power supply 206 and the main power supply 205, respectively. Once an abnormality is detected, the corresponding power supply is quickly cut off to prevent the fault from escalating. The air-disconnector is responsible for controlling each branch of the critical power supply or non-critical power supply. Each air-disconnector independently controls a power supply to protect the branch equipment.

The UPS power supply 206 stores the electrical energy input by the mains power supply 205 in the energy storage device in the form of DC. When the mains power input is normal, the UPS stabilizes the mains power and supplies it to various key interfaces for use, while charging the energy storage device. When the mains power is interrupted, the UPS immediately continues to supply the energy of the energy storage device to the key interfaces, achieving uninterrupted power supply to key equipment.

[0044] A surge protector SPD1 is provided in parallel with the mains power supply 205 to protect electrical equipment and systems from damage caused by overvoltage transients. When a transient overvoltage occurs in the system due to lightning strikes, switch operations, start-up and shutdown of large electrical equipment, etc., the voltage is quickly limited to a safe range, thereby protecting the safe operation of the electrical equipment.

[0046] Furthermore, the input of the interior lighting power supply 218, powered by UPS power supply 206, is also connected to the input of the emergency lighting power supply, and the output of the emergency lighting power supply supplies power to the emergency lighting. The output of the interior lighting power supply 218 is connected in parallel to the interior ceiling light, the left and right rear compartment lights, the PLC cabinet light, and the external cable compartment light. Switches are provided on each parallel branch to control the turning on and off of the corresponding light.

[0047] Furthermore, the output end of the roof equipment power supply 213 powered by the AC power supply 205 is connected in parallel with the left outer light, the right outer light, the lifting mast, and the ventilation fan, respectively, and switches are set on the left outer light branch and the right outer light branch to control the turning on and off of the lights.

[0048] The output end of the mains power supply 205 is also connected to the input end of the parameter display meter 201 , and the parameter display meter 201 is connected to the display power supply 216 , and the display power supply 216 supplies power to the parameter display meter 201 .

[0049] The mains power supply 205 is connected to the parameter display meter 201 via a wire, and the connection is achieved through connecting wires, including a live wire, a neutral wire, and a ground wire.

[0050] It should be noted that the power supply settings of the above-mentioned electrical components can be adaptively adjusted and can be arranged through the system principle circuit diagram to improve the flexibility and efficiency of the control method.

[0051] Working principle detailed description:

[0052] This AC control system, also known as a vehicle-mounted control and display system, is primarily used for AC power control in specialized vehicles, such as instrument vehicles, shower vehicles, and command vehicles. It provides centralized control of the vehicle's AC power supply. The power distribution control panel 2 has been optimized. A toggle switch 202 on the control panel switches between the mains and UPS, controlling the distribution of non-critical power from the mains and critical power from the UPS. The parameter display 201 on the panel monitors parameters such as the voltage, current, and frequency of the mains power supply 205.
