Description

轮胎压力监测装置 技术领域
本实用新型涉及轮胎压力监测领域，特别地，涉及一种可自编程的轮胎压力监测装置。
背景技术
轮胎压力监测(Tire Pressure Monitoring，TPM)传感器通常安装在轮胎内，可监测轮胎的压力、温度、转动状态等，并将监测到的状态转化为特定数据格式的信号以预置形式(比如无线射频的形式)发送给汽车内的接收单元，以便接收单元根据接收到的信号作出响应，并以预置方式(比如文字、声音等)将轮胎状态告知驾驶者，上述TPM传感器和接收单元即可组成一个向驾驶者反馈轮胎状态以保障行驶安全的胎压监测系统(Tire Pressure Monitoring System，TPMS)。
目前，TPM传感器按市场可分为两类：原厂配套TPM传感器和售后TPM传感器。原厂配套TPM传感器是供应商为不同的客户开发的具有特定数据格式的传感器并在新车出厂前进行装配，对于一个原厂配套TPM传感器而言，发送及接收的信号的数据格式是单一的，不同的供应商开发的原厂配套TPM传感器、同一供应商应不同客户要求开发的原厂配套TPM传感器所对应的数据格式都是不同的，因此，应用于两款不同的车、不同年份的同款车上的原厂配套TPM传感器是不能互换的，这也导致了市场上出现了上百种对应不同数据格式的原厂配套TPM传感器。
但是，原厂配套TPM传感器的工作动力来源是其内部配置的电池，该电池的使用寿命一般为5-10年，当电池耗尽或损坏时，则需要更换相同型号的TPM传感器，这就需要汽车经销商准备大量库存的TPM传感器才能够满足不同客户的更换需求，由于市场的不确定性，很可能会给销售商带来较大的资源浪费。
为解决上述问题，又出现了售后TPM传感器，大致包括如下几种：
第一种为可编程TPM传感器，其操作需要依赖于特定的编程工具(或编程设备)，工作原理可为将不同传感器对应的数据格式预先存储于编程工具中，再 通过预置传输方式将各个数据格式对应的软件代码输入给一个空白的传感器(该空白的传感器内可能需预先写入引导程序才能完成编程过程)，或者也可将多个数据格式预先存储于该传感器中，再由编程工具发出指令进行选择，对传感器进行编程结束后，传感器所发出信号的数据格式对应的代码是唯一的。该种可编程TPM传感器，可以被编入的数据格式种类可以包括很多种，因此对于经销商而言，只需要准备少数种类的该种传感器即可满足对不同需求的TPM传感器的更换，而且由于该种TPM传感器一次只能发送一种数据格式的信号，因此其电池的使用寿命相对比较长，但是该种传感器必须依赖于特定的编程工具才能工作，操作过程相对较复杂且具有一定的技术门槛，并且编程工具还存在需要升级等问题，此外现有的该种传感器的被编程次数是有限制的，重复使用性较差。
第二种为多协议TPM传感器，其工作原理可为将多种不同种类的数据格式以软件代码的形式输入传感器中，当达到预设响应条件则该TPM传感器会同时将所有数据格式的信号以无线的形式发送出来。该种TPM传感器无需额外的编程工具，但每次发送的信号对于一款车而言只有一个数据格式是有用的，其他数据格式都是无用的，因此对于电池来说，大多数的电能消耗都是无用的，电池寿命会受到影响，此外，传感器内能够存放的数据格式的类型是有限的，对于经销商来说还是需要具有一定库存量的该种TPM传感器才能满足不同客户的更换需求。
总之，现有的TPM传感器还不够理想。
实用新型内容
本实用新型所要解决的技术问题是提供一种轮胎压力监测装置，具有自编程的功能且操作简单，可延长使用寿命，且可兼容更多种类的数据格式，进而可有效减少经销商囤积原厂配套TPM传感器的库存。

用于通过预置传感器采集轮胎压力相关数据，并将采集到的数据发送给控制单元的数据采集单元；
用于接收编码输入单元发来的程序编码并存储，接收数据采集单元发来的采集数据，若所述采集数据符合预置触发条件，则调用特定程序根据确定的程序编码，将所述采集数据编码为对应数据格式的数据并发送给射频发射单元的控制单元；
用于接收控制单元发来的数据并以预设频率发送给车辆的预置接收单元的射频发射单元；
其中，所述编码输入单元中存储有对预置部件的操作方式与预设数据格式的第一对应关系表，所述控制单元中存储有预设数据格式与车辆类型的第二对应关系表。
进一步的，所述轮胎压力监测组件还包括用于接收控制单元在其存储空间不足时发来的存储指令，且根据所述存储指令接收并存储来自编码输入单元的程序编码的扩展存储单元；
相应的，所述控制单元还用于在存储空间不足时向扩展存储单元发送存储指令。
进一步的，所述控制单元包括：
将接收到的程序编码进行排列及存储，在符合预置触发条件时确定需使用的程序编码并发出执行编码的指令的引导子单元；
接收引导子单元的执行编码的指令并根据该指令调用特定程序将所述采集数据进行编码成对应数据格式的数据的执行子单元。
进一步的，在接收引导子单元的执行编码的指令之后，
所述执行子单元，还用于接收通过编码输入单元输入的新的程序编码，并将原有的程序编码与新的程序编码进行重组，以产生新的程序编码。
进一步的，所述轮胎压力监测组件还包括：用于建立高频通信通道的高频通信单元，以便射频发射单元将数据通过所述高频通信通道以高频形式发送至车辆的预置接收单元。
进一步的，所述轮胎压力监测组件还包括：用于建立低频通信通道的低频通信单元，以便接收并响应胎压监测系统诊断工具通过所述低频通信通道以低频形式发送的指令。
进一步的，所述预置传感器包括压力传感器、温度传感器、电池电压传感器、加速度传感器和角度传感器。
与现有技术相比，上述技术方案中的一个技术方案具有以下优点或有益效果：
在本实用新型提供的轮胎压力监测装置中，包括轮胎压力监测组件，其中包含存储单元、编码输入单元、指示单元、数据采集单元、控制单元、射频发射单元，通过编码输入单元将与预设数据格式对应的程序编码发送至控制单元且通过数据采集单元将采集的轮胎压力相关数据发送至控制单元，且通过指示单元及时显示程序编码被发送的状态，并通过控制单元在符合预置触发条件时调用特定程序根据确定的程序编码将采集数据编码为对应的数据格式并通过射频发射单元发送至车辆预置接收单元，并通过预置接收单元以预设方式告知驾驶者车辆轮胎的状态，该轮胎压力监测装置无需借助任何外部的编程工具进行设置及编程，其自身即可被重复地设定为预置的数据格式，操作简单且更便于用户根据需要进行修改，而且通过射频发射单元每次只发射一种或少数几种特定数据格式的数据，因此会大大节省该轮胎压力监测装置中的电池寿命，从而提升整个该轮胎压力监测装置的使用寿命，此外，由于可根据需要输入所需数据格式对应的程序编码并在后续操作中进行相应数据格式的编码操作，因此该轮胎压力监测装置可兼容更多种类的是数据类型，适用于更多种类型的车辆，进而可有效减少经销商囤积原厂配套传感器的库存量，降低经销商的成本。

编码输入单元12，用于根据对预置部件的操作方式所对应的预设数据格式来读取存储单元11中与该预设数据格式对应的程序编码并发送给控制单元15后，向指示单元13发送指示上述程序编码已被发送的信号。
其中，编码输入单元12中存储有对预置部件的操作方式与预设数据格式的第一对应关系表，比如预置部件为按钮，则对应关系表可包括用户触发按钮一次，则对应第一预设数据格式，用户触发按钮两次，则对应第二预设数据格式，等等，以此类推。
比如，当用户触发一次预置部件(比如按钮)，则可根据第一对应关系表确定用户想要系统产生的预设数据格式为第一预设数据格式，此时则可读取存储单元11中与第一预设数据格式对应的程序编码并发送给控制单元15，然后再 将指示第一预设数据格式对应的程序编码已被发送给控制单元15的信号发送给指示单元13。
指示单元13，用于接收编码输入单元12发送来的上述信号，并根据该信号向指示部件发送开启指令。
其中，该指示部件可为指示灯、指示语音播放器等，比如当指示单元13接收到编码输入单元12发送来的指示第一预设数据格式对应的程序编码已被发送给控制单元15的信号后，则可根据该信号向指示灯发送预设指令(该预设指令比如可为：第一预设数据格式对应的程序编码已被发送则该指示灯亮起一次，第二预设数据格式对应的程序编码已被发送则该指示灯连续亮起两次，依次类推)，以通过指示灯的开启次数及时显示所发送的不同的程序编码，以方便后续操作；再比如也可根据该信息向指示语音播放器发送预设指令(该预设指令比如可为语音播放“第一预设数据格式的对应的程序编码已被发送”等等)，以通过语音播放的形式及时告知用户所发送的不同的程序编码，以方便后续操作。
数据采集单元14，用于通过预置传感器采集轮胎压力相关数据，并将采集到的数据发送给控制单元15。

控制单元15，用于接收编码输入单元12发来的程序编码并进行存储，还用于接收数据采集单元14发来的采集数据，同时还可存储有预设数据格式与车辆类型的第二对应关系表。
若接收到的来自数据采集单元14的采集数据符合预置触发条件，则调用特定程序根据确定的程序编码将接收到的采集数据进行编码为对应的数据格式，然后将具有该数据格式的数据发送给射频发射单元16。
在控制单元15中隐含判断的功能，即判断来自数据采集单元14的采集数据是否符合预置触发条件，如果符合的话，则对该采集数据进行编码为对应的数据格式。
其中，预置触发条件可根据预置传感器的种类、车辆的具体情况等等进行设置，比如预置触发条件可包括轮胎压力小于30千帕等等。以轮胎压力数据为例，若接收到的轮胎压力为28千帕，则为符合预置触发条件。
具体的，控制单元15中可包括引导子单元和执行子单元。
其中，引导子单元，可用于将接收到的程序编码进行排列及存储，并且在上述符合预置触发条件时确定需使用的程序编码，比如可根据控制单元中存储的预设数据格式与车辆类型的第二对应关系表进行确定，然后向执行子单元发出执行编码的指令。
执行子单元，可用于接收引导子单元发来的执行编码的指令，并根据该指令调用特定程序对采集数据进行编码以生成对应数据格式的数据。
此外，若当来自数据采集单元14的采集数据不符合预置触发条件时，则可设定该控制单元15仅接收数据而不做任何后续动作。
进一步的，在接收到引导子单元的执行编码的指令之后，在符合特定的条件下，该执行子单元还可接收通过编码输入单元输入的新的程序编码，并将原有的程序编码与新的程序编码进行编码重组，以产生新的程序编码，产生更加符合需求的数据格式，以扩展该轮胎压力监测装置的适用性。
射频发射单元16，用于接收控制单元15发来的所述对应数据格式的数据并以预设频率发送给车辆的预置接收单元，以便该预置接收单元以特定的方式(比如语音、文字、图形等方式)告知驾驶者该车轮胎的状态。
进一步的，该轮胎压力监测组件1还可包括用于建立高频通信通道的高频通信单元，通过该高频通信单元可使得射频发射单元14将对应数据格式的数据通过该高频通信通道以高频形式发送给预置接收单元。
此外，现有的轮胎压力监测系统在使用过程中，通常会使用胎压监测系统诊断工具(也可称为TPMS诊断工具)对系统中的各传感器的工作状态进行诊断、检测等，但现有的TPMS诊断工具基本都没有编程功能，若需要增加编程功能则需要升级现有编程工具，但大部分的TPMS诊断工具并不能升级成编程工具，因此造成了使用上的不方便。
基于此，该述轮胎压力监测组件还包括：用于建立低频通信通道的低频通 信单元，以便接收并响应TPMS诊断工具通过所述低频通信通道以低频形式发送的指令，以使得该轮胎压力监测组件可与现有TPMS诊断工具直接兼容，不再需要因轮胎压力监测装置程序更新而对TPMS诊断工具进行升级、或将TPMS诊断工具升级为编程工具等操作，在实际应用中会节省非常多的人力物力。
电源单元17可为一电池，用于为轮胎压力监测组件1供电，以使得该轮胎压力监测装置可以正常工作。
参看图2，为本实用新型轮胎压力监测装置实施例二的结构框图。
在实施例二中，该轮胎压力监测装置在上述实施例一中的结构的基础上，还可包括扩展存储单元18，用于接收控制单元15在存储空间不足时发来的存储指令，且根据该存储指令接收并存储来自编码输入单元12发来的程序编码；相应的，控制单元15还用于在存储空间不足时向扩展存储单元18发送存储指令，以指示扩展存储单元18进行存储。由于控制单元的存储能力是有限的，因此设置了扩展存储单元，用以增加整个轮胎压力监测装置的存储能力，以存储更多类型的数据格式对应的程序编码，以适用于更多种类的车辆，进而适应更多用户的需求。
在本实用新型提供的轮胎压力监测装置中，包括轮胎压力监测组件，其中包含存储单元、编码输入单元、指示单元、数据采集单元、控制单元、射频发射单元，通过编码输入单元将与预设数据格式对应的程序编码发送至控制单元且通过数据采集单元将采集的轮胎压力相关数据发送至控制单元，且通过指示单元及时显示程序编码被发送的状态，并通过控制单元在符合预置触发条件时调用特定程序根据确定的程序编码将采集数据编码为对应的数据格式并通过射频发射单元发送至车辆预置接收单元，并通过预置接收单元以预设方式告知驾驶者车辆轮胎的状态，该轮胎压力监测装置无需借助任何外部的编程工具进行设置及编程，其自身即可被重复地设定为预置的数据格式，操作简单且更便于用户根据需要进行修改，而且通过射频发射单元每次只发射一种或少数几种特定数据格式的数据，因此会大大节省该轮胎压力监测装置中的电池寿命，从而提升整个该轮胎压力监测装置的使用寿命，此外，由于可根据需要输入所需数据格式对应的程序编码并在后续操作中进行相应数据格式的编码操作，因此该轮 胎压力监测装置可兼容更多种类的是数据类型，适用于更多种类型的车辆，进而可有效减少经销商囤积原厂配套传感器的库存量，降低经销商的成本。
本说明书中的各个实施例均采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似的部分互相参见即可。
以上对本实用新型所提供的一种轮胎压力监测装置进行了详细介绍，本文中应用了具体个例对本实用新型的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本实用新型的方法及其核心思想；同时，对于本领域的一般技术人员，依据本实用新型的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本实用新型的限制。
