ZP-89 8-code FSK auto-blocking equipment keeps the technical characteristics and features of the 4-code FSK auto-blocking equipment. It adopts integrated components and highly accurate crystal oscillator, which has increased the information capacity and improved the stability of the equipment. It is applicable for both 3-display and 4-display auto-blocking sections. Combined with 8-code FSK cab signal equipment, it can build up the multi-info FSK auto-blocking and cab signal system.

Functions and Characteristic

¡¡¡¡1¡¢  good anti-interference ability, applicable for steam engine, internal combustion engine and AC traction sections. 

¡¡¡¡2¡¢  meet the requirements of ground 3-display and 4-display auto blocking.

¡¡¡¡3¡¢  the FSK ground information could be directly used by cab signaling and the ground equipment is needless.

¡¡¡¡4¡¢  fast response, less than 2 sec.

5¡¢  conform with the fault-safe principle.

6¡¢  the equipment could be distributed or centralized installed. At present, centralized installation is mostly adopted.

¡¡¡¡7¡¢  For the redundancy of the system, the transmitter is hot stand-by, which is switched in case of faults, and receiver is doubled parallel working, which has malfunction detecting warning so that greatly improve the reliability of the system.

8¡¢  Complete FSK information, 8 codes selected from low frequencies of 8Hz¡¢9.5Hz¡¢11Hz¡¢13.5Hz¡¢15Hz¡¢16.5Hz¡¢17.5Hz¡¢20Hz¡¢26Hz¡¢30Hz.

9¡¢  when the rail is 1-¡Þ¦¸ km and the shunt resistance is0.06¦¸, the FSK auto-blocking can meet the adjusting and shunting requirement. The limited length of the non-electrified section is 1950m and 2100m, and the electrified length 1850m and 2000m. And the repeater point is needed in overlong sections.

¡¡¡¡10¡¢adopt occupied code sending or pre-superposition code sending mode to realize the route coding in stations.
