The invention discloses a tripping voice vibration prompting system and prompting method of grid equipment. An accident tripping monitoring module obtains a real-time alarm signal, generates a tripping accident report when a tripping accident occurs, transmitting the report to a GSM-SM modem, the GSM-SM modem sends the tripping accident report to a mobile operator network, and the mobile operator network forwards the report to a wrist type wearable intelligent terminal; GSM/GPRS communication module receives the tripping accident report and sends the report to a control module, the control module sends the received tripping accident report to a voice synthesis module, the voice synthesis module converts the report into a synthesized voice and plays the voice; and the control module obtains the acceleration speed of the wrist type wearable intelligent terminal in real time by a three-axis acceleration sensor and analyzes a current sleep state of an operator on duty; and when the operator is in a deep sleep state, a vibration module is controlled to make vibration to warn the operator on duty. The tripping voice vibration prompting system and prompting method have functions of multi-channel prompting, auxiliary judgment, and operator waking up; the warning modes are diversified; the warning effect is enhanced; site monitoring is flexible; and a phenomenon of accident processing delay caused by entrance of the deep sleep of the operator is avoided.
