The electrical block diagram of (substation)；In Figure 14, the crash sensor is attitude transducer.
Further application of the invention is illustrated with several application scenarios below.
Scene 1：1 work song station of No. 1 relay station in certain section monitors collision information, wakes up the Internet of Things at 1 work song station immediately
Warning message is transferred to main website by No. 1 relay station by net communication module, and warning message is transmitted to by main website by information sharing
Hospital, road emergency rescue department, road upkeep department, and each department makes an immediate response, Rapid Implementation rescue, and quick accident section is extensive
It is multiple current.
Scene 2：Someone drives a car traveling on a highway, and vehicle casts anchor suddenly, and service area is far away from tens kilometers
Outside, after vehicle is parked in Emergency Vehicle Lane by driver, manual pull station request rescue is triggered manually.
Scene 3：One patient of hospital of the city A is due to aggravation, and urgent need transfers hospital of the city B to, and the height between the city B of the city A
There are many fast road vehicle, and hospital proposes the application of quickly urgent through lane to traffic control center, and traffic control center is immediately
Control signal is issued, the Internet of Things Intelligent guardrail (substation) on expressway between the city B of the city A all becomes orange from green, mentions
Show that driver concedes the quick urgent through lane in left side, hospital of the city A ambulance reaches hospital of the city B in advance, and the state of an illness of patient obtains
Control.
In addition, the equipment of relay station and slave station in the present invention is mounted in box and all does water-proofing treatment, rainfall is avoided
Caused by failure.
Finally it should be noted that：The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
