技术领域technical field
本发明属于轨道交通售检票设备、门禁、出入控制、闸机、自动检票设备、物联网技术应用领域，具体涉及一种闸机通行传感器检测装置和方法。The invention belongs to the application fields of rail transit ticket sales and inspection equipment, access control, access control, gates, automatic ticket inspection equipment, and Internet of Things technology, and specifically relates to a gate passage sensor detection device and method.
背景技术Background technique
目前，应用于轨道交通售检票设备、门禁、出入控制、闸机、自动检票设备等领域的闸机都具有判定通过者行为的闸机通行逻辑控制装置，包括分别安装在两片闸机内的对射式红外光电传感器的发射端和接收端组合以及门单元控制装置(GCU)，发射端发射不可见波段的红外光，由接收端接收，简称传感器光路，行人进入通道后，其身体、随身物和携带行李会分阶段的阻挡不同组合的传感器光路，并以此形成不同的区状态参数。传感器接收端将这些状态参数传送给闸机门单元控制装置(GCU)，门单元控制装置(GCU)通过对状态参数的分析来判定通过者在闸机通道内的行为，当非法行为产生时需要通知门单元是否执行阻拦动作。At present, the gates used in the fields of rail transit fare collection equipment, access control, access control, gates, automatic ticket checking equipment, etc. all have gate passage logic control devices to determine the behavior of passers-by, including two gates installed in two gates. The combination of the transmitting end and the receiving end of the through-beam infrared photoelectric sensor and the door unit control unit (GCU). The transmitting end emits infrared light in the invisible band and is received by the receiving end. Objects and carry-on luggage will block different combinations of sensor light paths in stages, and thus form different zone state parameters. The receiving end of the sensor transmits these state parameters to the gate unit control unit (GCU) of the gate unit (GCU). The gate unit control unit (GCU) determines the behavior of passers-by in the gate channel by analyzing the state parameters. When illegal behavior occurs, it needs to Notifies the gate unit whether to perform a blocking action.
门单元控制装置(GCU)通过对状态参数的分析来判定通过者在闸机通道内的行为，当非法行为产生时需要通知门单元是否执行阻拦动作。但是当传感器组合中的发射端或接收端产生故障时，也会形成传感器光路不通的现象，产生错误的状态参数进而影响门单元控制装置的判断，或者当检测到非法的通过行为时，轨道交通运营方并不能确认是传感器故障导致的，还是通行逻辑算法中的缺陷造成的。The gate unit control unit (GCU) determines the behavior of passers-by in the gate channel by analyzing the state parameters, and needs to notify the gate unit whether to perform blocking actions when illegal behavior occurs. However, when the transmitter or receiver in the sensor combination fails, the optical path of the sensor will also be blocked, resulting in wrong state parameters and thus affecting the judgment of the door unit control device, or when an illegal passing behavior is detected, the rail transit The operator cannot confirm whether it is caused by a sensor failure or a flaw in the general logic algorithm.
近年，随着行业标准与规范的建立，售检票设备在各城市都设有相应的入围监测实验室，且行业产业链分化后，设备提供商不一定在项目完成后还是设备维护商，设备的运维基本以外包形式运作，第三方运维厂家未必熟悉设备状态的检测维护，目前也没有相应的检测闸机通行传感器的设备及方法，因此运维厂家无法实现传感器的实时检测。In recent years, with the establishment of industry standards and norms, fare collection equipment has corresponding shortlisted monitoring laboratories in each city, and after the industry chain is divided, equipment providers may not be equipment maintainers after the completion of the project. The operation and maintenance is basically outsourced. The third-party operation and maintenance manufacturers may not be familiar with the detection and maintenance of equipment status. At present, there is no corresponding equipment and method for detecting the passage sensors of the gates. Therefore, the operation and maintenance manufacturers cannot realize the real-time detection of the sensors.

In this way, the real-time status of the sensor and the monitoring results of whether the traffic logic is normal can be obtained clearly and intuitively.
本发明在原有传感器接收端与GCU的通讯链路(如图1所示)中，并联加入一个基于串口通讯的数据采集模块，GCU与传感器之间的数据收发交互均被此模块采集，如图2所示，J7是GCU物理电路板上的接口，一个闸机通道增加一个数据采集模块，该模块可采集此通道内的全部对射、漫反射传感器的状态。In the communication link between the original sensor receiving end and GCU (as shown in Figure 1), the present invention adds a data acquisition module based on serial port communication in parallel, and the data sending and receiving interactions between GCU and sensors are all collected by this module, as shown in Figure 1 As shown in 2, J7 is the interface on the GCU physical circuit board. A data acquisition module is added to a gate channel, which can collect the status of all through-beam and diffuse reflection sensors in this channel.
所述数据采集模块包括GCU信号采集电路、传感器信号采集电路；所述GCU信号采集电路与GCU连接，接收GCU向门单元发送的指令，并将其发送给通讯模块；所述传感器信号采集电路与闸机通道内的各个传感器的接收端分别连接，采集各个传感器的状态数据，并将其发送给通讯模块；所述通讯模块通过互联网将GCU向门单元发送的指令、各个传感器的状态数据发送给远程监控端。The data acquisition module includes a GCU signal acquisition circuit and a sensor signal acquisition circuit; the GCU signal acquisition circuit is connected to the GCU, receives an instruction sent by the GCU to the door unit, and sends it to the communication module; the sensor signal acquisition circuit and The receiving end of each sensor in the gate channel is connected separately, collects the state data of each sensor, and sends it to the communication module; the communication module sends the instructions sent by the GCU to the gate unit and the state data of each sensor to the gate unit through the Internet. Remote monitoring terminal.
所述传感器信号采集电路包括光耦隔离电路、模数转换电路；每个传感器的接收端与一个光耦隔离电路的输入端连接，光耦隔离电路的输出端与模数转换电路的输入端连接，模数转换电路的输出端与通讯模块连接。传感器状态的通、断变化，通过光耦隔离电路被转化为高、低电平。再通过数据采集模块的芯片处理，将高低电平转化为0、1(采用常规的模拟信号转换为数字信号的装置即可)，通过数据采集模块将0、1的状态以报文的形式通过串口发送给4G模块，由4G模块将报文输出至互联网。同时，数据采集模块采集GCU的工作状态，比如GCU向门单元发送了什么指令，这些指令都以报文的形式发送给远程监控端，远程监控端相当于在线监听GCU发出的指令。在远程监控端将报文接收，再逆向工程转换为传感器的通断变化。。The sensor signal acquisition circuit includes an optocoupler isolation circuit and an analog-to-digital conversion circuit; the receiving end of each sensor is connected to the input end of an optocoupler isolation circuit, and the output end of the optocoupler isolation circuit is connected to the input end of the analog-to-digital conversion circuit , the output end of the analog-to-digital conversion circuit is connected to the communication module. The on and off changes of the sensor state are converted into high and low levels through the optocoupler isolation circuit. Then through the chip processing of the data acquisition module, the high and low levels are converted into 0 and 1 (using a conventional device for converting analog signals into digital signals), and the status of 0 and 1 is passed through the data acquisition module in the form of a message. The serial port sends to the 4G module, and the 4G module outputs the message to the Internet. At the same time, the data acquisition module collects the working status of the GCU, such as what instructions the GCU sends to the gate unit, and these instructions are sent to the remote monitoring terminal in the form of a message, which is equivalent to online monitoring of the instructions sent by the GCU. The message is received at the remote monitoring end, and then reverse engineered into the on-off change of the sensor. .
该数据采集模块可将GCU与传感器组之间的通讯情况完全实时采集并进行存储(储存在电路中的ROM里，物理介质可以是CF卡、DOM盘、FLASH盘等多种类型。)，再把数据采集模块与4G串口模块进行连接(采用物理连接，串口通讯。)，由4G串口模块将采集到的通行行为的数据通过4G发射天线发送至互联网，如图2、图3所示。The data acquisition module can collect and store the communication between the GCU and the sensor group in real time (stored in the ROM in the circuit, and the physical medium can be CF card, DOM disk, FLASH disk, etc.), and then Connect the data acquisition module with the 4G serial port module (using physical connection, serial port communication.), and the 4G serial port module will send the collected traffic behavior data to the Internet through the 4G transmitting antenna, as shown in Figure 2 and Figure 3.
该数据采集模块采集的是传感器的状态变化情况，现有技术中传感器的状态只反馈给GCU，现在既反馈给GCU又反馈给数据采集模块。数据采集模块采集到后通过4G发送给远程监控端，远程监控端具有和GCU一样的嵌入式程序能将采集的数据图形化、信息化表达，从而可排查传感器状态，监控通行逻辑运行的情况。The data acquisition module collects the state change of the sensor. In the prior art, the state of the sensor is only fed back to the GCU, but now it is fed back to both the GCU and the data acquisition module. After the data acquisition module is collected, it is sent to the remote monitoring terminal through 4G. The remote monitoring terminal has the same embedded program as the GCU, which can graphically and informationally express the collected data, so as to check the status of the sensor and monitor the operation of the general logic.
远程监控端为管理服务器或第三方监控服务器(可建立在PC端)上，通过4G接收天线将采集数据进行接收，接收后通过与GCU具有同样逻辑判断条件的嵌入式程序对传感器状态进行监控与判断，并通过软件(例如采用C++编写，将传感器状态反应为图形的简单图形界面。)将原始的传感器状态数据进行图形化展示，即把传感器的光路畅通、光路被遮挡用图形的方式进行表达，实现了远程监控。The remote monitoring terminal is a management server or a third-party monitoring server (which can be built on a PC), and receives the collected data through a 4G receiving antenna. After receiving, the sensor status is monitored and monitored through an embedded program with the same logic judgment conditions as the GCU. Judgment, and through software (such as written in C++, a simple graphical interface that reflects the sensor state as a graph.) Graphically display the original sensor state data, that is, to express the sensor's smooth optical path and blocked optical path in a graphical way , to achieve remote monitoring.
