At present, our company's elevator wireless monitoring equipment has two models, one is analog wireless monitoring equipment LA-2510DT, and the other is digital wireless monitoring equipment LA-5840.
LA-2510DT is a wireless transmission device with a very high cost performance for elevator video surveillance. With high carrier frequency, better anti-interference, and receiving filter function, it can effectively reduce clutter signal interference. The device has a built-in 12dbi directional antenna. Under the same transmission power conditions, the transmission distance is longer and the signal is more stable. Small size, light weight, suitable for installation in the elevator shaft, and installation and debugging more convenient.
LA-5840 is a new generation of wireless video surveillance specifically for the elevator monitoring environment, innovative introduction of elevator digital wireless video surveillance solutions, its flexible deployment, simple maintenance, small interference, smart appearance, easy to install. At the same time, the wireless audio and video transmission method effectively avoids the loss of monitoring pictures and audio caused by the failure of elevators with the cable, and fundamentally improves a series of problems faced by elevator monitoring. Use up to 100 floors in the elevator.
The wireless monitoring equipment is installed in the elevator as follows:
The special wireless monitoring system for elevator installation is very simple. The transmitter is placed on the top of the car. The receiver is placed on the upper part of the patio (or the bottom of the well, depending on the position of the monitoring room. If the monitoring room is on the top floor, the receiver and antenna can be used. In the upper part of the well, otherwise in the lower part of the well, the signal is transmitted wirelessly between the transmitter and the receiver. The received video signal is sent to the monitoring room through the video cable, and the management personnel can monitor the running status of the elevator in real time.
We can produce the Boiler Pipe accordng to the ASTM A335 and ASME SA335 standards, such as the P11 steel pipe, P12 steel pipe, P22 steel pipe, P91 steel pipe, P92 steel pipe, P5 steel pipe, P9 steel pipe and P36 steel pipe. Yangzhou Chengde have been sold about 700000 MT boiler pipe to the world in recent 10 years and we share the 70% of export boiler pipe in china.
In the year of 2015, we win the first prize of National Science and Technology Progress Award by the program of [The innovative research & development, and application of steel pipes used in 600 a?? Ultra-super critical coal power generation unit".
YC has been granted a number of approval certificate by international institutions, such as ASME Nuclear pipe certificate, China Nuclear HAF certificate, 914mm Cylinder certificate, API monogram and certificate, ISO9001 by TUV NORD, ISO14001/OHSAS18001 by CQC, approvals from Shipping Classification Bureaus like DNV, RINA, ABS, Lloyd, GL, Bureau Veritas, and permit of exporting to Europe as PED 2014/68/EU and AD 2000 certificates for pressure pipes, CPD (Construction Products Directive), etc. and these certificates support the development of international sales market.
