Multi-host type gas detector system

The invention discloses a multi-host type gas detector system. The multi-host type gas detector system comprises a plurality of first gas detectors and a plurality of second gas detectors, wherein the plurality of first gas detectors are arranged in a danger release source area, each first gas detector comprises a first detection module, a first control module, a first display module, a first alarm module, a first uploading communication module, and a first synchronous communication module, the plurality of second gas detectors are arranged in an area which danger may relate to, and each second gas detector comprises a second control module, a second display module, a second alarm module, and a second synchronous communication module. When the gas concentration value acquired by the first detection module is higher than the gas concentration threshold set in the first control module, the first control emits an alarm signal to the first alarm module, and the second synchronous communication module can communicate with the first synchronous communication module in order to receive the gas concentration value and the alarm signal detected by the first detection module.
