Description

多功能交通路口电气控制柜 技术领域
本发明涉及控制柜领域,尤其涉及一种多功能交通路口电气控制柜。
背景技术
目前,尚不存在交通路段行人数据的采集平台,也没有基于行人数据确定客流指数的分析机制,更没有基于客流指数现场无线发送给附近公交车车队以控制其发车频率的无线通信设备。这样的无线通信设备一般希望设置在现场,以保证数据的实时性和准确性,然而对于各个交通路口来说,公共设备本身就不少,以及除了行人、车辆通行空间之外,剩余的空间非常有限,在每一个交通路口处新增一套数据采集以及数据通信设备,不太现实。
因此,需要一种多功能交通路口电气控制柜,能够利用现有的交通路口的控制柜,对其进行改造以增加现场数据采集设备和现场数据通信设备,确定交通路口附近的客流指数,为附近各个公交车车队提供即时的发车频率,使得附近车队发车频率与现场等车人数相适应,从而最大程度地利用现有的城市公交资源。
发明内容

具体实施方式
下面将参照附图对本发明的多功能交通路口电气控制柜的实施方案进行详细说明。
公交车是城市交通重要的代步工具,给城市居民带来了出行方便。然而,对于公交车车队来说,空载是他们不愿意看到的,对市政交管部门来说,居民等车难也不是他们所愿意看到的,因此如何减少空载时间并避免过多人等车情况的发生,是公交车车队和市政交管部门需要解决的难题之一。
现有技术中,公交车车队一般凭借历史经验来判断各个交通路段在各个时间段的人流数量,以自行选择发车频率。然而,交通路段的人流数量是实时变化的,与历史经验有可能大相径庭,这样,容易导致交通路段人多时,很多公交车停止运营,耽误了居民乘车,或者交通路段人少时,很多公交车扎堆,导致大部分公交车空载的情况发生。
为了克服上述不足,本发明搭建了一种多功能交通路口电气控制柜,能够建立在各个交通路段的数据采集平台,对交通路口的实时人流数量进行准确采集,并基于实时人流数量为附近公交车车队的运营提供参考,从而整合城市公交车资源,尽可能地为城市居民的出行提供方便。
为了克服上述不足,本发明搭建了一种多功能交通路口电气控制柜,改善机器人的主体架构使其能够适合输电线路现场环境,设计有针对性的电容感应式冰层传感器对现场导线冰层进行准确检测,并引入无线传输技术保障现场设备之间以及现场与远端之间的通信畅通。

另外,通用分组无线服务技术(General Packet Radio Service)的简称,他是GSM移动电话用户可用的一种移动数据业务。GPRS可说是GSM的延续。GPRS和以往连续在频道传输的方式不同,是以封包(Packet)式来传输,因此使用者所负担的费用是以其传输资料单位计算,并非使用其整个频道,理论上较为便宜。GPRS的传输速率可提升至56甚至114Kbps。
GPRS经常被描述成“2.5G”,也就是说这项技术位于第二代(2G)和第三代(3G)移动通讯技术之间。他通过利用GSM网络中未使用的TDMA信道,提供中速的数据传递。GPRS突破了GSM网只能提供电路交换的思维方式,只通过增加相应的功能实体和对现有的基站系统进行部分改造来实现分组交换,这种改造的投入相对来说并不大,但得到的用户数据速率却相当可观。而且,因为不再需要现行无线应用所需要的中介转换器,所以连接及传输都会更方便容易。如此,使用者既可联机上网,参加视讯会议等互动传播,而且在同一个视讯网络上(VRN)的使用者,甚至可以无需通过拨号上网,而持续与网络连接。
GPRS分组交换的通信方式在分组交换的通信方式中,数据被分成一定长度的包(分组),每个包的前面有一个分组头(其中的地址标志指明该分组发往何处)。数据传送之前并不需要预先分配信道,建立连接。而是在每一个数据包到达时,根据数据报头中的信息(如目的地址),临时寻找一个可用的信道资源将该数据报发送出去。在这种传送方式中,数据的发送和接收方同信道之间没有固定的占用关系,信道资源可以看作是由所有的用户共享使用。由于数据业务在绝大多数情况下都表现出一种突发性的业务特点,对信道带宽的需求变化较大,因此采用分组方式进行数据传送将能够更好地利用信道资源。例如一个进行WWW浏览的用户,大部分时间处于浏览状态,而真正用于数据传送的时间只占很小比例。这种情况下若采用固定占用信道的方式,将会造成较大的资源浪费。
采用本发明的多功能交通路口电气控制柜,针对现有技术无法为公交车车队提供基于交通路口即时客流信息进行发车频率控制的技术问题,通过改造现有的交通路口的控制柜,将其作为数据采集和数据通信控制平台,提供交通路口的准确的实时客流指数,并进 一步为附近各个车队提供相应的发车频率,从而在保证车队经济利益的同时,为城市居民提供方便的公交服务。
可以理解的是,虽然本发明已以较佳实施例披露如上,然而上述实施例并非用以限定本发明。对于任何熟悉本领域的技术人员而言,在不脱离本发明技术方案范围情况下,都可利用上述揭示的技术内容对本发明技术方案做出许多可能的变动和修饰,或修改为等同变化的等效实施例。因此,凡是未脱离本发明技术方案的内容,依据本发明的技术实质对以上实施例所做的任何简单修改、等同变化及修饰,均仍属于本发明技术方案保护的范围内。
