System and method for reversible monitoring of mobile vehicles

technical field

The present invention relates to a monitoring system and method, in particular to a reversible monitoring system and method suitable for mobile vehicles.

Background technique

Generally speaking, the monitoring system used for mobile vehicles mostly monitors the internal conditions of the mobile vehicle through the external monitoring system. In addition, when a special situation occurs inside the mobile vehicle, the mobile vehicle can send a communication request to the outside , through the external response and communication between the two parties, the external can obtain the image information inside the mobile vehicle through the monitoring system, and based on this, the external can provide assistance and solve problems in real time.

For example, at present, most elevators have a distress button for external calls. When an emergency occurs in the elevator, press the distress button to send a communication request to the guard room, and wait for the guard room personnel to respond before using the walkie-talkie to communicate. , and then use the guard room to request support from the security unit (or elevator maintenance personnel). If the guard room does not respond in real time, you can keep pressing the SOS button in the elevator until the guard room personnel give a response.
