Embodiment

For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with embodiment and with reference to accompanying drawing, the utility model is further described. It is to be understood that these describe just exemplary, and do not really want to limit scope of the present utility model. In addition, in the following description, eliminate the description to known features and technology, unnecessarily obscure concept of the present utility model to avoid.

Embodiment one: shown in composition graphs 1, comprises micro-chip 1, key circuit 2, flare-up light 3, emergent ambry magnetic valve 4, oxygen magnetic valve 5 for subsequent use, speaker 6, emergency source of electric power 7, charging control switch 8, power supply 9, lowering and stabilizing blood pressure module 10, infrared sensor 11, temperature sensor 12, pressure transmitter 13 and elevator door switch 14;Temperature sensor 12, pressure transmitter 13 first link together and are connected with micro-chip 1 external interrupt 0 pin; Infrared sensor 11 is connected with micro-chip 1 external interrupt 1 pin; Power supply 9 is connected with micro-chip 1 energization pins by lowering and stabilizing blood pressure module 10; Power supply 9 is also connected with emergency source of electric power 7 by charging control switch 8; Charging control switch 8 and emergency source of electric power 7 are all connected with micro-chip 1, and micro-chip 1 controls charging control switch 8; Key circuit 2, flare-up light 3, emergent ambry magnetic valve 4, oxygen magnetic valve 5 for subsequent use, speaker 6 are all connected with micro-chip 1, and micro-chip 1 controls key circuit 2, flare-up light 3, emergent ambry magnetic valve 4, oxygen magnetic valve 5 for subsequent use, speaker 6; Flare-up light 3, emergent ambry magnetic valve 4, oxygen magnetic valve 5 for subsequent use, speaker 6 are also connected with emergency source of electric power 7 simultaneously, and when power supply 9 is cut off, emergency source of electric power 7 is flare-up light 3, emergent ambry magnetic valve 4, oxygen magnetic valve 5 for subsequent use, speaker 6 are powered; Micro-chip 1 is connected with elevator door switch 14, and controls elevator door switch 14; Infrared sensor is installed on the both sides of sedan-chair railway carriage or compartment door, is mounted in pairs, it is necessary to install 5 right; Emergent ambry is positioned at above sedan-chair railway carriage or compartment; Pressure transmitter is positioned at the outside in sedan-chair railway carriage or compartment, and temperature sensor is positioned at the inside in sedan-chair railway carriage or compartment, and pressure transmitter and temperature sensor all need 6.

Principle of work: when elevator runs time, micro-chip 1 can detect whether environment instantly is without disaster scenarios it, if without under disaster scenarios it, as shown in Figure 2, power supply 9 charges to emergency source of electric power 7, and infrared sensor 11 works and data are passed to micro-chip 1, whether the side that micro-chip 1 can detect elevator cab door has the stop of people or thing, if had, just wait that time of 5 seconds carries out detecting the stop whether having people or thing again, until just carrying out, during the stop of nobody or thing, operation of closing the door.

Such as Fig. 3, elevator works at normal operation, pressure transmitter 13 and temperature sensor 12, and result is passed to micro-chip 1, and micro-chip 1 judges whether external environment is fire or earthquake, if normal circumstances, electricity, 9 charge to emergency source of electric power 7, and elevator keeps normal operation. If running into disaster, power supply 9 is cut off by external force, causes lift car non-transformer to be powered. Now emergency source of electric power 7 works, it is possible to for micro-chip 1 is powered, and micro-chip 1 internal processes makes key circuit 2 effective. Micro-chip 1 now waits pressing of button, if now personnel press emergent button, flare-up light 3 is opened, emergent ambry magnetic valve 4 is opened, maintaining life requisite for indicator of trapped personnel provides, oxygen magnetic valve 5 for subsequent use is opened, and avoids oxygen to exhaust and causes personnel to suffocate, speaker 6 can also work, and helps indicator of trapped personnel and the external world to get in touch. If no one presses button, then proving that personnel have not had nobody in life or sedan-chair railway carriage or compartment, micro-chip 1 can terminate program.
