The Wielingen class was a class of four multi-functional frigates constructed for and operated by the Belgian Naval Component. In service from 1976 to 2008 with the Belgians, three of the class were sold to Bulgaria for service with the Bulgarian Navy beginning in 2004. The fourth, Westhinder, ran aground in 1988, was decommissioned in 1993 and was scrapped.
The Belgian government began studies in 1969 for a new type of escort that would meet the requirements of escort missions in the North Sea and English Channel during the Cold War. The design would also only be limited to weapon systems already in service with or under development by NATO navies. The design also emphasized seaworthiness, automation and watertight integrity. The weapons systems, with the exception of the Sea Sparrow surface-to-air missile (SSM) were French. The radar and tactical data systems were Dutch and the hull and machinery were constructed in Belgium. As part of the project, the Belgian government made Belgian shipbuilding participation mandatory in the construction of the new ships.
The frigates feature an action information centre between decks and the ships could be split into two independent gas-tight citadels in the case of nuclear, biological or chemical warfare. All machinery could be controlled from a central control station. The vessels measured 103.0 metres (337 ft 11 in) long between perpendiculars and 106.4 m (349 ft 1 in) overall with a beam of 12.3 m (40 ft 4 in) and a draught of 5.6 m (18 ft 4 in). The ships had a light displacement of 1,880 tonnes (1,850 long tons) and 2,283 t (2,247 long tons) at full load. By 2004, the light displacement had increased to 1,940 t (1,910 long tons) and to 2,430 t (2,390 long tons) at full load.
The ships are propelled by a two-shaft combined diesel or gas (CODOG) system. This is composed of a single Rolls-Royce Olympus TM3B gas turbine creating 21,000 kilowatts (28,000 shp) and giving the frigates a maximum speed of 28 knots (52 km/h; 32 mph) or two Cockerill CO 240 V12 diesel engines creating 4,500 kW (6,000 bhp) with a maximum speed of 20 knots (37 km/h; 23 mph) on both diesels or 15 knots (28 km/h; 17 mph) on just one. These turned controllable pitch propellers. The frigates have a range of 4,500 nautical miles (8,300 km; 5,200 mi) at 18 knots (33 km/h; 21 mph). The vessels also had four 500 kW diesel alternators for electric production. They had a complement of 160 including 15 officers in Belgian service.
The Wielingen class were armed with four launchers for MM38 Exocet anti-ship missiles, later converted to two twin launchers. They were equipped with a Mark 29 octuple launcher for eight RIM-7M Sea Sparrow SAMs. These were later upgraded to the RIM-7P model. The frigates also mount a single 100-millimetre (3.9 in)/55 calibre modèle 68 naval gun, one six-barrelled Creusot-Loire 375 mm (14.8 in) anti-submarine warfare (ASW) rocket launcher with Bofors rockets, and two catapults for L5 torpedoes. The class was fitted with two eight-barrelled Corvus chaff launchers, a Sagem Vigy 105 optronic director, a Signaal DA-05 air/surface search radar, a WM-25 surface search radar, SQS-510 hull-mounted sonar, and the SEWACO IV tactical data system with Link 11 capability. They were also given Argos AR 900 intercept electronic support measures and SLQ-25 Dixie torpedo decoy system.
Wandelaar was designed as a platform capable of multiple uses as an escort during the Cold War in the North Sea and English Channel. The vessel uses weapons and sensor technology from NATO counterparts, which was one of the reasons the ship was acquired by the Bulgarian Navy in 2004. The frigate is currently in active service.
The construction programme of four ships was approved by the Belgian government on 23 June 1971 and an order was placed with two Belgian shipyards in October 1973. The vessel was laid down on 28 March 1975 by Boelwerf at Temse, Belgium. Wandelaar was launched on 21 June 1977, named after the Wandelaar sand bank off the coast of Belgium, near Zeebrugge, as the third ship in the Wielingen class. The frigate was later commissioned on 3 October 1978 with pennant number F912. Wandelaar was based at Zeebrugge.

Our company has developed its own photovoltaic tracking control system, including the integration of "AI + solar tracking" technology applications, providing customers with "hardware + software + data + service" multi-functional solutions. The system automatically calculates the trajectory of the sun, azimuth, and altitude of the location at any moment according to the local longitude, latitude, time, and program. Furthermore, it automatically issues tracking commands according to the current position of the sun and controls the operation of the motor actuator to achieve real-time tracking of the sun by PV modules and thus increase the power generation. Meanwhile, the supporting software system enables the owner and operator of the tracking PV plant to fully control the real-time operation of the plant, so as to complete the operation and maintenance of the plant in an efficient and safe condition.

The intelligent tracking electrical control system includes an intelligent communication box NCU, solar tracker controller TCU, and a monitoring platform SCADA. NCU, the core brain of the tracking control system, connected with TCUs through LoRa or Zigbee, performs command issuance and data collection. Each TCU is responsible for the rotation of the tracking bracket motor. NCU obtains weather data from an anemorumbometer such as wind speed and direction through 485 wired in real-time; NCU communicates with SCADA through 485 wired or 4G/5G/Zigbee and other wireless to control the ZhuiKe operation and maintenance of the upper computer station. In automatic tracking mode, the system will automatically issue tracking commands according to the current trajectory of the sun and control the operation of motor actuators to ensure that the PV modules track the sun in real-time to increase the power generation.
FREQUENTLY ASKED QUESTIONS OF SOLAR TRACKER
Q
How do solar panels track the sun？
A
According to the local longitude, latitude, and time, the solar tracker controller automatically calculates the movement trajectory of the sun at the current moment and the azimuth and altitude angle of the location, and it also automatically issue tracking commands according to the current position of the sun and controls the motor to ensure that the relationship between the PV panel and the incidence angle of the sun is always perpendicular.
Q
What is solar tracking system？
A
Our company tracking system is made of three basic units: Tracker control unit (TCU), Intelligent communication box (NCU) and solar tracker monitor (SCADA).
