The laser pointer company will perform the system reform

 The laser pointer  company will perform the system reform.
Frequency tunable laser beam divergence angle and small, can effectively avoid the interaction between the probe beam caused by the leakage alarm coverage; laser beam divergence angle is small, beam focus, it can make use of high optical power can be more effective to overcome the dust attenuation caused by, effectively reduce false alarms; single wavelength laser beam, effectively prevent other light sources (such as the subway lights, site lighting, etc.) of the interference, reduce false alarms; assisted debugging tools make debugging more accurate, system stability is more good; response time by using the environment in the subway between 5ms-1000ms adjust the setting, the system features and better reliability. The production preparation of laser pointer  is of much importance. Automatic and manual operating modes: In automatic mode, the screen door closed, the system began to work for the normal operation mode; in manual mode, regardless of platform screen door is closed, are in work mode, convenient system testing. When the screen door closed, no gaps remain, the host alarm panel LED is green. When the screen door closed, the gap was stranded, the host panel warning light turns red; until the risk of exclusion, host panel warning light turns green. Host panel with the power supply indicator. Host function with adjustable time delay detection.
PSD Laser Donghua laser security systems company in Shanghai Xujiahui station after 5 months of testing, performance and stability, the Shanghai Metro Corporation After the test, the Tung Wah Group of Companies PSD laser safety of laser protection system assessment is no false positives stable performance, in line with the requirements of the Corporation. Shanghai Corporation decided in Shanghai Metro Line 1 and Line 4 curve points to start the installation Donghua PSD laser laser's security system. Xujiahui station equipment put into operation the film images, the station line station, 186 meters long. Three-beam laser beam from the site were the height of the ground 300mm, 500mm, 900mm. Tung Wah Group of laser products through the Shanghai Metro Corporation of testing, beginning in early March 2008 in the Shanghai Metro Line 1 and Line 4 for installation. To March 2009, the product has been put into operation in Shanghai Metro one year, equipment and stable, functioning and effective. The personnel responsibility of laser pointer  is good for the development of laser pointer  company.
