Node detector adopts highly stable CAN-BUS bus to realize the communication of each node, utilized microwave and infrared sensor to come detection vehicle, each node does not rely on zone controller just can realize communication separately, and has finished the process of inducing under a total zone controller is coordinated.
Vehicle detection uses microwave and heat to release infrared sensor, can output 1Hz under the situation of movement of objects signal to about the 10Hz, object rolls away from, then no signal output.
When vehicle enters, at first delay time of arm processor internal initialization is 1 second a timer, and be to stop counting, the count value zero clearing, level state changes on the pin after vehicle sails into, this change arm processor can make an immediate response, and under this state change situation with the timer zero clearing and restart.As long as pulse signal frequency maintains more than the 1Hz, timer can not produce and interrupt overflowing so, and the vehicle existence remains " very ".
When vehicle leaves, at first enter the explanation of principle with reference to above-mentioned vehicle, vehicle leaves back sensor no signal output, in case processor after 1 second, timer interrupts, in the program of having no progeny timer is stopped also zero clearing of counting.The vehicle existence is set to " vacation ".
Sail the pulse signal of meeting output 1Hz into when sensor receives vehicle, signal is carried out being input to ARM7 microprocessor judges and processing after the shaping to 10Hz.After microprocessor is confirmed to be normal signal, there are on message that vehicle enters, this message bus all nodes to receive, but have only the node in the safe distance of numbering this node serial number after could normal reception after filtering by the CAN bus broadcast.In case send such message, the node in the safe distance is just followed this node and together red light is lighted, and expression has vehicle in safe distance.After vehicle leaves this node, sensor pulse-free signal output, processor learns that vehicle leaves, immediately by message that CAN-BUS bus broadcast vehicle leaves.Behind the sign-off, red light might not extinguish, and will continue also to judge whether the node in the safe distance before it does not all have vehicle, if just extinguish, extinguishes red light again and lights amber light otherwise will wait in the safe distance that other node vehicle has left all.
Lamp fault detection is fixed as and detected in one minute once, and each node independent detection, node detection packing failure message after the fault sends to the CAN controller module by CAN-BUS bus broadcast, conveys to Surveillance center by the CAN controller module again.ARM controller inside carries multi-channel a/d converter, and when the lamp power supply detected, directly the supply voltage to pilot lamp detected, in case detect numerical value less than 10V or recognize it greater than 20V and be fault.Testing process is consuming time to be no more than 1 millisecond.Pilot lamp is connected to lamp drive circuit two branch roads, and one is that bright lamp drives branch road, and another is a detection branch.During lamp self detection, at first bright lamp is driven branch road and forbid (extinguishing lamp), the logical again detection branch that goes up, if the detection branch electric current is normal, lamp is normal, it normally is fault about half that no current or electric current have only.Whole process is consuming time to be no more than 50 milliseconds.
Referring to Fig. 3, zone controller comprises regional power module 6, RS232 communication module 8, two CAN controller module 7.
Wherein, regional power module 6 comprises the switching power supply that connects the 220V AC power.Because of the 24V exterior line power supply under the situation that a plurality of nodes connect, can occur that pressure drop is excessive to cause the node cisco unity malfunction, so outside line input power supply has substituted the 24V direct supply with the AC power of 220V, reduced cost and guaranteed power supply quality.The zone power module has used switching power supply, and output 5V supply voltage has added anti-thunder tube (ceramic gas discharge tube), lightning protection effectively on the circuit design.
7 of two CAN controller moulds comprise arm processor and two CAN transceivers of signal interconnection, and the CAN transceiver connects CAN-BUS bus.The model of arm processor is LPC2119, and its inside carries two CAN controllers, and the CAN controller hardware is finished CRC check automatically, and total line length reaches the baud rate that 10Km can also reach 5Kbps.The CAN transceiver is the CTM1050 isolated form CAN bus transceiver that Guangzhou Zhou Ligong single-chip microcomputer Development Co., Ltd produces.Communication distance is crossed and can be added repeater when far away prolong communication distance on bus.All there is toggle switch can adjust baud rate easily on zone controller and the node detector.
Zone controller adopts highly stable CAN-BUS bus to realize the control of CAN bus relaying, collector node information and total system, Surveillance center is connected with zone controller by the RS232 fiber optic that optical fiber directly arrives on the zone controller limit, and zone controller and Surveillance center have just realized both-way communication.
Under the situation of the total line length distance communication of CAN-BUS, communication speed will be received the influence of bus physical characteristic, two CAN transceivers have been installed on the zone controller to link to each other with two CAN controllers of ARM controller inside, bus is carried out relaying, under identical baud rate, prolong communication distance, improved bus stability.
Its principle of work is:
1, CAN relaying: the relaying principle is fairly simple, and two CAN controllers are transmitted mutually and also set up the reception buffer circle in software, prevents zone controller obliterated data when timely deal with data.
2, collect bus node information: node detector under normal circumstances can be finished faults itself and detect, and carries out vehicle and judges.When node detector self broke down, node all can be broadcasted corresponding information when vehicle entered the node detecting area and leaves the node detecting area on CAN-BUS bus.Zone controller does not filter any information on the bus, handles and these information are all passed to Surveillance center by the RS232 communication module.Surveillance center obtain these information just can be in real time simulation on the man-machine interface demonstrate on the bus lamp of each node bright, go out, failure condition.
3, Control Node: zone controller control input mode has Surveillance center by issue an order the button input control on control and self hardware of RS232 communication module.Input control situation is arranged at every turn, and zone controller will be translated input command and be broadcast on the bus by the CAN controller, and the data that node can the filtration zone controller can be translated Control Node oneself state again to data.
Safe distance is subjected to visiometer to control, and minimum safe distance can be accomplished 16 meters, and the most very much not limit depends on the total number of bus node.The safe distance that visibility is more little is long more.Stroboscopic is that node self takes place, and just can change cycle strobe and stroboscopic dutycycle as long as revise timing parameters.Zone controller is when sending modification stroboscopic information, and the stroboscopic of each node can not allow flicker asynchrony phenomenon occur synchronously.
4. whether detection node: whether normal mode is passive detection to the communication of zone controller detection node, just do not send any detection information and just can detect node can normal communication on bus.
Because of CAN-BUS bus is that the forms of broadcasting send data, so the information controller that all nodes send can both be received, zone controller has been created a state table in processor memory, if certain ID node has sent data, just extend this as 1 in the position of corresponding this ID in the state table so, whether have every 5 minutes preprocessor statistic behavior table look-ups and over halfly do not filled in 1 ID, if having, so error message is sent to Surveillance center, last cleared condition table continues monitoring bus.
In addition, when required distance of inducing control more in short-term, also can not use zone controller, by CAN-BUS bus interconnection, and each node detector directly communicates with Surveillance center by the TCP/IP procotol and is connected between each node detector.This kind conversion is also in protection domain of the present utility model.
