Fig. 2 is a slave unit functional block diagram of the present invention.
The specific embodiment
System of the present invention comprises main equipment and slave unit.Main equipment is installed in the locomotive head, can see read-out clearly with the engineer and be advisable; Slave unit is carried (size, weight are equal to present general mobile phone) by the Ground Operation personnel.The Ground Operation personnel can be tracking worker, railway public affairs system site operation team or other task groups etc.After system puts into operation, master-slave equipment will be made corresponding processing according to different warnings (simultaneously with information), avoid the generation of disaster accident to the full extent.If enable the ground linked system, the locomotive that the ground linked system fully can emergency braking be sailed into is really accomplished early warning, control, and is perfectly safe.Present device adopts wireless network to communicate, and the wireless distances between main equipment and slave unit surpasses 300 meters, lays suitable words and can satisfy the distance (about 1000 meters) that locomotive stops.Display unit is 2.4 inches color LCD read-outs, and alarm unit is the alarming horn of 2W.
The staff installs slave unit (preferably at a distance of more than at least 2 kilometers) respectively the slave unit corresponding work mode is set at the two in early warning interval (being the set-point), open slave unit, makes its early warning in 24 hours.Slow down, blow a whistle or stop according to the order that receives slave unit after when locomotive arrives apart from more than 300 meter of set-point, receiving the signal that slave unit sends.If there is the workmen in the early warning interval, they hear warning, can withdraw the scene behind the sound of blowing a whistle, and wait locomotive to construct through early warning interval later again, advance just locomotive has been crossed can raise speed behind the early warning interval.Whole process is automatic, safety, and is very easy to use.Floor mounted is succinct, and equipment is gently little, and is easy to carry, and without manual intervention, all automatic early-warnings stop automatically behind the opening of device.
Slave unit (roadside equipment) working process is as follows:
At first, there is the device start switch slave unit inside, and only slave unit is just in running order when opening, and is in dormant state when not opening.
Secondly, slave unit has five kinds of mode of operations, specifically sets according to the field condition during the early warning:
1, tracking worker pattern: only blow a whistle;
2, deceleration blast mode: except that blowing a whistle, contain the value of geard-down speed: " decelerating to XX kilometer/hour ";
3, car-parking model immediately: contain distance value: " apart from 1000 meters of accident points " apart from accident point;
4, pattern is passed through in deceleration: the value that contains geard-down speed: " decelerating to XX kilometer/hour ";
5, Actuator Test Modes: only use during factory inspection.
At last, after mode of operation is selected, in case after entering mode of operation, slave unit just sends early warning information one time every 550mS, till closing or cutting off the power supply.
Main equipment (locomotive equipment) work is as follows:
At first, there is the device start switch main equipment inside, and only main equipment is just in running order when opening, and is in dormant state when not opening.
Secondly, enter mode of operation after, equipment enters the automatic reception state, is used to receive satisfactory 4 kinds of early warning information that slave unit sends, and makes corresponding warning according to early warning information and handle; If when respectively being provided with slave unit, need discern, in order to avoid wrong report by software at the two ends in early warning interval.Equally, because slave unit is in the transmission early warning information of not stopping, main equipment is only handled once after receiving early warning information.
Main equipment is specifically handled as follows according to the early warning of early warning information:
1, the early warning information of receiving is to find the tracking worker: show and blow a whistle, warn; This information of loopback simultaneously;
2, early warning information is a construction section: show and blow a whistle, decelerate to XX kilometer/hour, the information warning of loopback simultaneously;
3, a dangerous tip: show the place ahead danger, please stop immediately! The general distance of fault is 1000 meters.
4, deceleration area: show that the place ahead road conditions are bad, decelerate to XX kilometer/hour.
