CONSTITUTION: Each reference threshold is set up for a fault error margin and a cyclic redundancy check(CRC) error margin according to nodes. Whether communication between a base station manager(BSM) and each high capacity inter-processor communication(IPC) control assembly(HICA), inside a gateway code division multiple access(CDMA) interconnection network(GCIN), local CDMA interconnection network(LCIN) and base station transceiver subsystem(BTS) interconnection network(BIN) is normally performed or not. If the communication is normally performed, each set threshold is respectively transmitted to the HICAs of the GCIN, LCIN, BIN through the BSM. The transmitted thresholds are respectively transmitted to each node of the GCIN, LCIN, BIN. A fault error rate and a CRC error rate are calculated. The calculated fault error rate and the CRC error rate are respectively compared with a reference fault error margin and CRC error margin according to each node. If the calculated fault error rate and the CRC error rate are larger than the reference fault error margin and CRC error margin, a corresponding node is decided to have a fault. Information on fault generation is transmitted to the BSM in each HICA at predetermined intervals.

Abstract: PURPOSE: A vacuum compression preventing device of a scroll compressor is provided to prevent breakage of a hermetic terminal due to vacuum compression and to avoid degradation of reliability due to thermal degradation of components by restraining vacuum compression with intermediate pressure. CONSTITUTION: A scroll compressor includes a high vacuum preventing unit. The high vacuum preventing unit comprises a valve housing(110) formed in a fixed scroll, a valve member(120) slidingly inserted into the valve housing to communicate an intake pressure section(Sl) with a discharge pressure section(Sh) of a casing or isolate the intake pressure section from the discharge pressure section, and an elastic member(130) interposed between the valve housing and the valve member to apply elasticity to sliding of the valve member. In over-compression or pump-down of the compressor, all the refrigerant gas in the intake pressure section is discharged to the discharge pressure section. Then, an intermediate pressure area(112) of the valve housing as well as an intermediate pressure chamber of a compression chamber is vacuumized. The addition of the pressure load applied to an intermediate pressure negative pressure face of the valve member and the elasticity of the elastic member is smaller than the pressure load of the discharge pressure section. The valve member is thrust toward the intermediate pressure area and a discharge pressure side gas hole(113a) is opened. Simultaneously, a portion of the discharge gas in the discharge pressure section backwardly flows to the intake pressure section through an intake pressure side gas hole(111a) after flowing into a discharge pressure area(113) of the valve housing. Thus, vacuum state of the compressor is removed. Thereafter, the valve member rebounds to the discharge pressure area against the pressure load of the discharge pressure section by the refrigerant gas returned to the intake pressure section. Thus, the intake pressure side gas hole and the discharge pressure side gas hole are closed.
