Background technology
In recent years, the congested in traffic subject matter that day by day becomes urban transportation, teleseme has also formed four kinds in pedestrian's street crossing trigger-type teleseme, multi-period timing teleseme, induction type teleseme and point coordination teleseme etc. on function.At present; Teleseme begins to develop to function directions such as public traffic in priority, special duty commander, local self-adaptation, multiple agent and communication specifications; But these improvement all are in vertical expansion along the teleseme function; And in the horizontal, often ignored the diversity of urban road grade crossing and the relevance of urban traffic flow, on teleseme technical scheme and structure, do not provide and support fully; Do not possess unified control and implementation specification comprehensively for diversified crossing type and traffic flow situation, some crossing even can't achieve effective control.Therefore; These telesemes are in the system implementation process; Different crossings need be provided with the various signals phase place, some situation even can't realize that signal lamp need adopt the different modes of connection with magnetic test coil because case is too complicated; Installation and enforcement technical ability to user and engineering contractor have had very high request, have strengthened training, enforcement and maintenance cost.On the other hand; Complete teleseme includes functions such as master control, communication, lamp control, flow detection and fault detect; Present teleseme has adopted integrated circuit board not divide the structure of module (adopting the control panel of an integral body) or one-level modularization (adopting the array mode of master control borad, communication board, lamp control plate, check-out console); In production, debugging, installation and maintenance process, a lot of inconvenience be can bring like this, production and operating efficiency influenced.
Summary of the invention
Can unify the universal method and the multistage modular construction of realization urban road grade crossing signal timing dial and installation for solving not possessing of existing in the prior art with standardizing; Thereby can not realize the signal control problem of urban road grade crossing effectively, the present invention proposes a kind of teleseme that has universal control method and multistage modular construction.
For solving the problems of the technologies described above, the present invention adopts following technical scheme to be achieved:
Grade crossing universal control method and multistage modular construction teleseme; Said teleseme has adopted universal control method; It is characterized in that signal controlling demand, grade crossing classified that the signal controlling phase place at comprehensive every type of crossing is provided with demand according to access connection traffic flow; Form unified phase place and divide standard, and on teleseme software algorithm and hardware configuration, support.
Further, the present invention also has following technical characterictic: hardware configuration adopts multistage modular design, and the one-level module is made up of the master control borad and system backplane, each one of the detection base plate that with technological ARM 32 8-digit microcontrollers of high-performance Cortex-M3 are core; The secondary module is made up of phase place mainboard and each one of detection mainboard; 3-level module is made up of 6 blocks of phase driven plates and 8 blocks of vehicle detection plates.Module boards at different levels are connected by serial bus.
Compared with prior art, advantage of the present invention and good effect are following:
1, the present invention has adopted intersection general controls technology; Have teleseme back panel wiring standard, signal lamp wiring standard and three engineering construction standards of detecting device wiring standard; Constitute the general wiring standard of teleseme, make teleseme installation and maintenance become very easy and standard; Simultaneously, adopted multistage modular structure, finally realized the general controls of grade crossing according to the requirement design of general controls.
2, the signal timing dial adjustment is convenient.Be provided with owing to adopted unified phase place to divide, making the signal timing dial operation at different crossings have unified rule can follow, and has improved the validity and the high efficiency of signal timing dial.
3, lopsided crossing involved in the present invention is adjacent near excessively crossing in the city road network in essence; The magnitude of traffic flow has very strong correlativity; Existence needs the strict phase place that keeps the time difference, and the prior art scheme adopts 3 telesemes to adopt time synchronized or networking to coordinate control usually, but adopts the mode of time synchronized to exist 3 teleseme times can not be synchronous; Thereby cause the fluctuation of the phase place time difference, networking is coordinated control and is also suffered the unreliable negative effect that brings of network service.Teleseme of the present invention is divided through carrying out rational phase place, adopts the mode of the inner phase coordination of a teleseme, can guarantee the reliability service of the phase place time difference.
