The invention discloses a transparent roof employing photovoltaic plates, and the roof is provided with a window. The interior of the window is provided with transparent window, and two photovoltaic plates are disposed exactly below the transparent glass. The ceilings at the front and rear sides of the photovoltaic plates are fixedly provided with grooved rails, and the left and right sides of the grooved rails are provided with guide grooves. The photovoltaic plates are fixed on a plurality of lateral box irons, and the box irons are fixed on a plurality of longitudinal round steels. Two ends of the round steels are bent into fulcrum bars, and the fulcrum bars pass through the guide grooves of the grooved rails to be hinged to rollers. The rollers are inserted into the grooved rails. Two ends of the box irons are fixed on longitudinal connecting rods, and connecting rods of the photovoltaic plates are fixed on the lateral side plates. The lateral side plates abut against the side walls of the grooved rails, and the side plates are fixedly provided with a plural of supporting lugs. The supporting lugs are in screwed connection with lateral screw rods through linear bearings, wherein one end of each screw is fixedly connected with a rotating shaft of a motor through a shaft coupler, and the other end of the screw is hinged to a bearing seat. The photovoltaic plates are used for replacing a sun shield, so the roof can achieve the independent power supply, and facilitates the opening and closing of a transparent window of the roof.

The invention provides a catenary power supply device for thermal insulation of EMUs and a power supply method thereof. The catenary power supply device for thermal insulation of EMUs includes an industrial power supply and a transformer (3), the industrial power supply and the transformer The input end of the device (3) is connected, and the transformer device (3) can change the voltage of the industrial power supply to an output voltage of 25kV and supply power for the arrival and departure catenary (9) or the parking line catenary (11). The catenary power supply device for thermal insulation of EMUs adopts the nearest common industrial power supply, transforms its voltage to 25kV, and connects to the catenary of the arrival and departure lines or storage lines of parked EMUs for thermal insulation of EMUs. It not only realizes the independent power supply to the arrival and departure line or the catenary of the parking line, but also avoids setting up a dedicated power supply line from the adjacent substation to the station, which can save a lot of engineering investment and operating costs.

The invention provides a multifunctional environment monitoring sensor, which can realize simultaneous monitoring on various environment parameters.

The invention discloses a boost grouping controller of a storage battery module. The boost grouping controller consisting of a storage battery module composed of a plurality of single storage batteries, a super capacitor, a discharge switch current-limiting voltage regulator, a charge switch current-limiting voltage regulator, a DC-DC (direct-current-direct current) power supply booster, a storage battery module monitor, a pulse transformer, a rectifier, an output power supply filter, a temperature regulator, a storage battery module charging and temperature regulation controller, a storage battery module charging and discharging controller and a micro controller. According to the invention, an operation method of storage battery module boost grouping is realized, thus the storage batterymodules can be isolated mutually and operate individually after grouping, the mutual influence of the storage battery modules after grouping can be avoided, the service life of a storage battery set is improved, and the boost grouping controller has the characteristic of convenience in implementation.
