Description
Technical field
The present invention relates to alarm technique field, more particularly to a kind of engineering truck collision-proof alarm method and device.
Background technology
The anti-collision alarm system of the engineering trucks such as current fork truck is mainly comprising three parts：Ranging base station, anticollision label, report
Alert device.Within the system, ranging base station needs the distance between measurement and anticollision label in real time, and whether monitoring anticollision label enters
Danger zone.
Common practice is：
Ranging base station is constantly in reception state, and the moment monitors the ranging information of anticollision label, due to engineering truck movement velocity
Comparatively fast, in order to grasp the distance between people and engineering truck in time, anticollision label is sent with very high frequency to ranging base station
Ranging information.
The defect of such way is：
Equipment power dissipation is big, and cruising time is short.Because ranging base station is constantly in reception state, anticollision label is constantly in transmission shape
State, so ranging base station and the communication module of anticollision label are constantly in continuous firing, and the power consumption of communication module is accounted for entirely
Equipment overwhelming majority power consumption, for using for chemical cell power supply engineering vehicle odometry warning system, cruising time is not more than
24 hours；And the time that user of service then wishes continuation of the journey, the longer the better, charge frequency is more low better.
The content of the invention
It is a primary object of the present invention to propose a kind of engineering truck collision-proof alarm method and device, ranging base can be passed through
The agreement stood between anticollision label communicates, dynamic regulation communication frequency, reduces power consumption, lifts endurance.

As shown in figure 1, in the present embodiment, a kind of engineering truck collision-proof alarm method, including：
S10, anticollision label send registration information to ranging base station；
S20, ranging base station receive the registration information and set up with the anticollision label and communicated to connect；
S30, ranging base station and anticollision label agreement communication occasions point and all dormancy；
S40, when the communication occasions point of agreement arrives, ranging base station and anticollision label, anticollision label and ranging base are waken up successively
Stand communication, ranging base station obtains the distance between anticollision label and ranging base station, is again introduced into dormancy；
S50, judge whether the distance is less than default distance threshold, if so, then into step S60, send sound and light alarm；It is no
Then, into step S70, holding normality, do not alarm.
In the present embodiment, it is possible to communicated by the agreement between ranging base station and anticollision label, dynamic regulation communication frequency
Rate, reduces power consumption, lifts endurance.
In the present embodiment, ranging base station is fixed on indoor and outdoor engineering truck, and anticollision label is worn on engineering truck work
Make on the personnel in region, ranging base station monitors the relative distance of anticollision label in 100m radius in real time, when people is close to dangerous
During scope, the ranging for preventing collision alarm on engineering truck is touched, so as to send sound and light alarm, effectively prevents, prevent engineering truck
Collision, which rolls the high-risk accident such as employee, to be occurred.
In the present embodiment, ranging base station is divided into the Continued communication stage with the communication mode of anticollision label, arranges the rank that communicates
Section, sleep for electricity saving stage.Anticollision label is first started shooting in the communication of Continued communication phase requests, and anticollision label can be constantly to ranging base
Stand and send registration request, it is desirable to which the delivery time set up between communication linkage, different anticollision labels is random；Then ranging base
Establish machine on standing by cable and be in the Continued communication stage, ranging base station receives the registration request that all anticollision labels are sent at random in 10s
Information, replys agreement and sets up communication linkage and arrange next communication occasions point, ranging base station and anticollision label with each label
It is switched on after timer whole dormancy and is in low-power consumption battery saving mode, now into the sleep for electricity saving stage；When the communication of agreement
After time point has arrived, ranging base station wakes up in reception state first, when all anticollision labels are according to the communication arranged before
Punctum wake up successively and with ranging base station communication, while ranging base station can with each anticollision label arrange next time communication occasions
Point, is now in arranging stage of communication；Each anticollision label with after the completion of ranging base station communication enter sleep for electricity saving state,
Ranging base station is now again introduced into sleep for electricity saving rank with also entering sleep for electricity saving state after the completion of all anticollision label communications
Section；When the call duration time point arranged next time to after, ranging base station enters agreement stage of communication, Ran Houzai with anticollision label
