所述交通信号控制机,用于对交通控制信息进行解析,从中得到交通控制信号控制所述信号灯,它包括数据校验模块31,用于对交通控制信息的控制权限和合法性进行校验,当校验合格时,从中分离出控制信号传送给信号控制模块;信号控制模块32,用于驱动所述控制信号灯5。 The traffic signal controller for controlling traffic information is parsed, derive the control signal traffic lights, which includes a data check module 31, a traffic control authority and legitimacy of the information for verification, when passing the check, separates therefrom a control signal to a control module signal; and a signal control module 32, for driving the control signal lamp 5. 在所述无线接收器2和交通信号控制机3之间串接的通信接口4为串行接口,当然也可以采用并行接口。 3 in series between the wireless receiver 2 and a traffic signal controller to the communication interface 4 serial interfaces, parallel interfaces are of course possible.

图1中的无线发送器1为无线遥控器或短信息(SMS)发送器,相应的,所述无线接收器2为无线信号接收器或短信息接收器。 1 in FIG. 1 the wireless transmitter is a wireless remote control or a short message (SMS) transmitter, and correspondingly, the wireless receiver is a wireless signal receiver 2 or the short message receiver. 也就是说,图1描述了交通信号控制机单点工作时的遥控控制方式和短消息控制方式。 That is, FIG. 1 depicts a remote control when the traffic signal control unit and a single-point short message control work. 下面以短消息控制方式说明该实施例的实现。 In the following description control message implemented according to this embodiment. 具体实现时,无线发送器1采用移动终端(如手机)或具备了SMS接口的手持设备,无线接收器2采用短消息接收器,所述短消息接收器2和接口4可以内嵌入交通信号控制机3中,并且交通信号控制机需要预先配置移动号码。 In specific implementation, the wireless transmitter 1 using the mobile terminal (e.g. a mobile phone) includes a handheld device or SMS interface, the wireless receiver 2 using a short message receiver, the short message receiver 2 and the interface 4 can be embedded within the traffic signal control machine 3, and the traffic signal controller requires pre-configured mobile number. 交通信号控制机3的数据校验模块31由CPU、FLASH存储器(用于存储控制程序)、SRAM存储器、串行口(该串行口用于向信号控制模块32发送数据)等组成,主要负责数据的校验和对外数据的发送,信号控制模块32由CPU、FLASH存储器(用于储控制程序)、SRAM存储器、串行口、I/O驱动单元组成,主要根据用户预先的参数设定和用户临时编码发送的控制信号或指令对信号灯5进行控制。 Traffic signal controller data check module 31 of the CPU, FLASH memory (for storing a control program), the SRAM memory, a serial port (the serial port 32 for transmitting data to the module control signal) and the like, is responsible for checksum of the data and external data transmission, a signal control module 32 by a CPU, FLASH memory (for storing a control program), the SRAM memory, serial interface, I / O drive units, mainly based on user pre-set parameter, and user control signals or instructions sent by the temporal coding of the signal lamp 5 is controlled. 用户通过移动终端(如:手机)或具备了SMS接口的手持设备,直接对选定的交通信号控制机进行远程控制,命令格式可如下:控制密码6位+控制指令+结束符。 Mobile user terminals (such as: a mobile phone) includes a handheld device or SMS interface directly to the selected traffic signal controller for remote control, the command format is as follows: control password control instruction + 6 + terminator. 如用户要对某个交通信号控制机进行控制时,只需要向这个控制机的号码发送短消息,在消息的头6位是用户的密码如123456,后面为控制码,如CPN表示红绿灯切换到下一个相位,“、”为命令间隔符,NOW立刻执行,“。”为结束符等。 Such as when a user wants to control the traffic signal controller, this number is only necessary to send a short message to the control unit, during the first six bits of the message as the user's password is 123456, the back of the control code, such as switching to a traffic light showing CPN the next phase, "" the command symbol interval, NOW executed immediately, "." is a terminator and the like. 整条信息可以为123456CPN、NOW。 The entire message may be 123456CPN, NOW. . 短消息运营商会自动在短消息头中插入发送者的手机号码。 Operators will automatically insert the short message sender's phone number in the message header. 将控制数据通过短消息服务商发送到该交通信号控制机所指定的移动号码,同时可以从服务商处得到消息是否发送成功的确认信息。 The control data is sent to the traffic signal controller number specified by the mobile service provider a short message, and can obtain confirmation message successfully sent information from the service provider. 设置在交通信号控制机中的SMS接收模块接收到服务商发送过来的SMS数据后,通过串口4将控制数据送到交通信号控制机,控制机首先将数据在内设的数据校验模块31进行校验,数据校验模块将短消息进行数据拆分,在短消息中得到用户的短消息发送号,和预先设置在校验模块31中的短消息发送号进行校对,如果该发送装置可以对交通信号进行控制,则进入密码校对过程,否则丢弃该数据。 Traffic signal controller is provided in the receiving module receives the SMS SMS data sent from the service provider, the control data through the serial port 4 to the traffic signal controller, the control data in the first machine equipped with a data check module 31 check, data check module data split short message, the user of the short message in the short message transmission number, and transmitting the message number previously set in the proofreading checking module 31, if the transmission means may traffic signal control, then enter the password proofreading process or discard the data. 在密码校对时,该模块31将分析出来的密码和与预先存储的密码列表中的密码进行对比,如果密码正确,则进入数据合法性校验过程,否则,丢弃该数据。 When the password collation, the analysis module 31 will be out of the password and the password pre-stored list of passwords in contrast, if the password is correct, the process proceeds to verify the legitimacy of the data, otherwise, discards the data. 在数据合法性校验时,根据用户预先设置的参数上下限、参数互锁条件,对控制信息进行合法判断,例如用户根据现场的实际情况,设定在东西向直行相位后应该是东向南左转相位,否则可能会出现车辆无法放空的情况,但是用户在东西向直行相位时要求直接到南北向直行相位,此时,用户的红闪时间设定为最高10秒,在数据合法性校验过程中,如果红闪时间大于10秒,如15秒,则认为数据非法,丢弃数据。 When checking the legitimacy of the data, according to the lower limit of the parameter, the parameter interlock condition preset by the user, the control information is determined valid, for example, according to the actual site of the user, after setting the phase to what should be straight south east left turn phase, otherwise the vehicle can not be venting may occur, but the request directly to the user in a straight north-south phase, this time, the red flash of time a user is set to a maximum of 10 seconds when things go straight to phase in the data legality school course of the experiment, if the red flashing time is more than 10 seconds, such as 15 seconds, the data is considered illegal, the data is discarded. 如果控制信息都通过数据校验模块31的校验,则从数据中解析出控制数据或信号通过串口进入信号控制模块32。 If the verification control information 31 through a data check module, from the parsed data signals or control data through the serial signal into the control module 32.
