Embodiment
Further describe technical scheme of the present invention below, but described in claimed scope is not limited to.
A kind of intelligent traffic light control system being applicable to underground transportation as shown in Figure 1 and Figure 2, comprises vehicle detection part, PLC control section, topworks and HMI part; Described vehicle detection part is connected to the input interface of PLC control section, and described topworks is connected to the output interface of PLC control section, and described HMI part is connected to the data bus of PLC control section; Described vehicle measurement unit is divided and is at least comprised the vehicle detecting sensor being embedded in underground and the relay being connected to inductive coil; Described topworks at least comprises the red light and green light that are arranged on fork road place, down-hole.
Described PLC control section core adopts SIEMENS S7-200, and IO interface is on-the-spot I/O.
PLC controls its essence is and carries out I/O conversion by certain algorithm, and this conversion is given physics realization.And I/O conversion is exactly the process of information processing, physics realization can exclude the interference signal exactly, is applicable to control scene.This control making PLC can easily realize controlled device.
Vehicle detecting sensor detects information of vehicles and imports PLC in conjunction with relay information into by input interface, after CPU process, storing, through the logical operation of program, order is flowed to the topworkies such as traffic lights by output interface by result, realize the Intelligent Transformation of lights state.
Owing to there being the traffic lights of 2 groups or more in intelligent traffic light control system, the co-ordination so how realized between each group of lights state is also the problem that intelligent traffic light control system needs to solve.Certainly we write corresponding program can to often group traffic lights, but this method not only can make system become more complicated, also can increase the failure rate of system.Adopt PPI communication then can well address this problem.Therefore, the communication between described PLC control section and topworks is PPI communication.PPI communication be S7-200 communicate most economical, the simplest mode, be because: PPI is the specialized protocol exchanging information between S7-200 type PLC, and it is a kind of point-to-point protocol; In a PPI communication network, only need a main frame, and only need programme to main frame; The hardware of PPI communication only needs a Profibus cable and two Profibus-DP joints.
Described PLC control section data bus adopts RS485.The RS485 serial communication of S7-200PLC and autonomous Design alternating interface between man and computer HMI is utilized to realize the message exchange of traffic light system and monitor staff, so this traffic light system is made not only can to play the effect directed traffic, the traffic conditions of monitor staff to this section can also be realized understand in real time, down-hole situation is presented in face of monitor staff more intuitively.And monitor staff can also be operated lights state by HMI, the traffic disturbance that some emergency case (as: device damage, the system failure etc.) cause so just can be avoided.
Described topworks also includes electronic shooting device.
Described vehicle detecting sensor is inductive coil.The mode of landfill inductive coil is adopted to carry out the detection of vehicle, its principle carrys out detection vehicle by the change of the inductance value of detection metal object on inductive coil, coil is by the coiling of multiturn wire, imbed underground, filling concrete, goes between to detecting device, passes through when there being vehicle, detecting device senses the change of inductance intensity, and is outputed signal by relay through inner intelligent computing.As shown in Figure 3, after vehicle leaves loop A, relay B is closed until vehicle leaves coil B, and vice versa, and the advantage of this kind of way of output is the turnover direction that can be judged vehicle by the elder generation of relay closes afterwards, thus makes writing of program more rigorous.
Principle of work of the present invention is: first, by vehicle detecting sensor, contact vehicle is confirmed, vehicle sends signal to PLC after confirming, logical operation through PLC programming does counting process to vehicle, PLC can make a record contact vehicle fleet size on the one hand afterwards, various places PLC is when carrying out PPI communications exchange information on the other hand, and main frame sends status command according to the logical operation of program to traffic lights, makes it correctly direct traffic; Then, by the RS465 serial communication of PLC, traffic light system and long-range HMI are contacted, thus enable monitor staff understand down-hole traffic conditions, under emergency case, also can command down-hole traffic by HMI.
