The present application relates to an elevator safety system, an elevator system, and an elevator safety control method. The elevator safety system (10) includes a plurality of elevator safety chain sections connected in series and assigned to individual floors (110, 120, 130) of an elevator. Each of the elevator safety chain sections includes a hall door switch (1101, 1102, 1201, 1202, 1301, 1302), an inter-floor limit switch (1103, 1203, 1303), a hall door bypass switch (1106, 1206, 1306) and a limit bypass switch (1105, 1107, 1205, 1207, 1305, 1307) arranged in series, and a processing circuit (1100, 1200, 1300) for controlling on-off of the various switches (1101, 1102, 1103, 1105, 1106, 1107, 1201, 1202, 1203, 1205, 1206, 1207, 1301, 1302, 1303, 1305, 1306, 1307). The safety system (10) of the present application is configured to additionally conduct the elevator safety chain section of the current floor (120) when the elevator hall door is in the abnormally opened state, and at the same time of trying to automatically release the passengers to be rescued, the stability of running or stopping the elevator system is ensured. The car is prevented from pinching passengers, and the safety and reliability of the elevator system are improved.
