The Raspberry Pi 4 Model B is one of the popular Raspberry Pi range of single board computers. It offers ground-breaking increases in processor speed, multimedia performance, memory, and connectivity compared to the prior generation Raspberry Pi 3 Model B+ while retaining backward compatibility and similar power consumption. For the end user, Raspberry Pi 4 Model B provides desktop performance comparable to entry-level x86 PC systems.
Key features include a high-performance 64-bit quad-core processor, dual-display support at resolutions up to 4K via a pair of micro-HDMI ports, hardware video decode at up to 4Kp60, up to 8 GB of RAM, dual-band 2.4 / 5.0 GHz wireless LAN, Bluetooth 5.0, Gigabit Ethernet, USB 3.0, and PoE capability (via a separate PoE HAT add-on). The dual-band wireless LAN and Bluetooth have modular compliance certification, allowing the board to be designed into end products with significantly reduced compliance testing, improving both cost and time to market.

Small diesel generator set is a diesel-fuelled internal combustion engine driven alternator small power generation equipment, power range is usually between 7-30kW, by the diesel engine, generator, control box and fuel tanks and other core components, suitable for emergency power supply or mobile scene.
The units are usually air-cooled, and some models are equipped with water-cooled cooling structure to improve efficiency, and the silent design can control the noise at 65-73dB. The structure integrates shock-absorbing spring base, universal wheels and handles to support mobile deployment. Standard features include voltage/current monitoring, battery starter, and optional ATS automatic switching and remote start. Technical improvements include a spiral tube cooling system with a ventilated electric fan for synergistic cooling, as well as multiple protection mechanisms such as low fuel consumption (205g/kw.h) and automatic voltage regulation [1].
With integral silent cabinet 80db at 7 meters
Display: speed, water temperature, oil pressure, and with overspeed, high water temperature, low oil pressure alarm stop function
DN150 quick coupling
Diesel tank 50L
In the case of the same parameters, the equipped pump is the same as the diesel engine, the response size is not different, and the 40HQ cabinet can only be installed 4 sets. The length of the second round is not much smaller.
Manual start/stop mode - Electronic control panel selects manual mode, one key to start, one key to stop.
Automatic start-stop mode - electronic control panel AUTO one-key automation; utility power outage automatic start,
utility power incoming automatic shutdown.
Emergency stop mode - The unit is equipped with an external emergency stop button safety device, realising one-key stop in emergency.
Backup Start Mode - Car type key ignition start.
Note: To avoid the failure of the electronic control panel to start the unit
and add the standby type double insurance start, in the emergency power outage needs
to use the generator set is more secure!
