Description
Technical field
The present invention relates to health monitoring field, particularly relate to a kind of cab driving personnel's health monitor device.
Background technology
Taxi, Taiwan is called taxi, Guangdong and Hong Kong and Macao and is called that taxi, Singapore and a Malaysian band are then called moral scholar; Being a kind of vehicles charged by meter, general relatively other vehicles of charge are high. Taxi English " TAXI " is the abbreviation of " taximeter ", is " meter " or " speedometer ". TAXI calls the turn spelling equally at nine national languages in fact: English, French, German, Swedish, Danish, Norwegian, Spanish, Dutch, Portuguese.
Taxi occupies one seat because it is dexterous convenient in urban public transport, and even some middle-long distances travelling, guests, in order to save worry, is also ready to employ taxi and be unwilling in person to drive. The while that taxi bringing trip easily for people, also traffic problems served by band, and the fuse cord of these traffic problems has objectively also subjectivity. Objective factor includes the vehicle trouble of taxi own, and subjective factor includes the driving condition of taximan.
The monitoring of taxi is concentrated in objective factor by prior art, and to the driver driven a taxi, corresponding monitoring means are limited, it it is more the video monitoring to cab-getter position, even if there being some monitoring means for driver's cabin, also more is detection to limited physical quantitys such as cabin interior temperature, humidity, air pressure, lacks the detection of the physiological status to driver, say nothing of employing when driver status exception, notify the communication mechanism of passenger in time.
But actually, the driving condition of driver is extremely important, on the one hand, it is likely to occur driver's spirit hypertonicity or ill situation, if not notifying that other staff carry out rescuing and replacing driving, it is easy to the economic loss caused casualties, on the other hand, being likely to situation driver's dangerous driving occur, at this moment generally the physiological parameter of driver there will be some omens.
As can be seen here, prior art exists techniques below problem: (1) lacks effective physiological driver's condition detecting device; (2) effective physiological parameter early warning mechanism is lacked; (3) the urgency communication passage that can promptly trigger and help passenger to contact at hour of danger is lacked with the foundation of taxi operation center.
