本发明涉及危化品储运领域，具体涉及一种可降功耗的智能感知终端和应用其的方法。The invention relates to the field of storage and transportation of hazardous chemicals, in particular to an intelligent sensing terminal capable of reducing power consumption and a method for applying the same.
背景技术Background technique
在危化品储运技术领域，通常对危化品储运设备的实时监控的要求较高，监控之首要为实时位置监控。对监控终端、货物的实时位置进行定位和跟踪，有利于监控终端、货物安全，方便商家对物流实现快速调度和调配，进而实现高效的商业化运作。而现有的危化品储运技术领域对危化品储运设备的监控力度不高，这样造成物流信息不清晰，终端信息混乱。In the field of hazardous chemical storage and transportation technology, there are usually high requirements for real-time monitoring of hazardous chemical storage and transportation equipment, and the first priority of monitoring is real-time location monitoring. Positioning and tracking the real-time location of monitoring terminals and goods is conducive to monitoring terminal and goods safety, and is convenient for merchants to quickly schedule and allocate logistics, thereby achieving efficient commercial operation. However, the existing hazardous chemical storage and transportation technology field does not monitor the hazardous chemical storage and transportation equipment very well, which results in unclear logistics information and chaotic terminal information.
在现有的技术中，尚未有对危化品储运设备进行有效的实时监控的方法。由于危化品多为易燃易爆的化学品，而且盛装危化品的罐体外形多样，工厂环境复杂，因而对危化品进行监控的产品要具备防爆要求，外形小巧，同时还须满足自供能、耐低温等要求。在无外部电源的情况下，实现持续续航也是一个技术难题。In the prior art, there is no effective real-time monitoring method for hazardous chemicals storage and transportation equipment. Because most hazardous chemicals are flammable and explosive chemicals, and the tanks containing hazardous chemicals have various shapes and complex factory environments, the products that monitor hazardous chemicals must meet explosion-proof requirements, be small in size, and at the same time meet the requirements of Self-supply, low temperature resistance and other requirements. In the absence of an external power supply, it is also a technical problem to achieve continuous battery life.
当前市场上的户外位置监控方案中大多使用卫星定位和基站定位。两种方案存在一定的缺陷：卫星定位精度高，但是功耗大，室内信号不稳定；基站定位的精确度不稳定。Most of the outdoor location monitoring solutions on the market currently use satellite positioning and base station positioning. The two schemes have certain defects: the satellite positioning accuracy is high, but the power consumption is large, and the indoor signal is unstable; the accuracy of the base station positioning is unstable.
因此，有必要提出一种可降功耗的智能感知终端和应用其的方法，以至少部分地解决上述问题。Therefore, it is necessary to propose an intelligent sensing terminal with reduced power consumption and a method for applying the same, so as to at least partially solve the above problems.

具体实施方式Detailed ways
在下文的描述中，给出了大量具体的细节以便提供对本发明更为彻底的理解。然而，对于本领域技术人员来说显而易见的是，本发明实施方式可以无需一个或多个这些细节而得以实施。在其他的例子中，为了避免与本发明实施方式发生混淆，对于本领域公知的一些技术特征未进行描述。In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that embodiments of the invention may be practiced without one or more of these details. In other instances, some technical features known in the art are not described in order to avoid confusion with the embodiments of the present invention.
为了彻底了解本发明实施方式，将在下列的描述中提出详细的结构。显然，本发明实施方式的施行并不限定于本领域的技术人员所熟习的特殊细节。For a thorough understanding of the embodiments of the present invention, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art.
参考图1和图2，对根据本发明的一个优选实施方式所提供的智能感知终端和应用该智能感知终端的方法进行描述。在本实施方式中，智能感知终端用于智能监控设备，即智能感知终端与智能监控设备共同工作，其中，智能监控设备包括设置在不同位置处的多个基站。需要说明的是，本文所说的“智能感知终端用于智能监控设备”指的是智能感知终端既可以形成为一个独立的部件并应用于智能监控设备，也可以与智能监控设备共同工作从而形成为智能监控设备的组成部件。智能感知终端用于对危化品储运设备进行实时监控。智能感知终端安装在危化品储运设备(在本实施方式中具体地为化工罐)上。智能感知终端包括壳体和固定在壳体内的终端系统。优选地，壳体上喷涂有导电漆，在不屏蔽定位模块的天线信号的情况下，智能感知终端能够将危害静电通过壳体传递至化工罐，并通过化工罐接地。Referring to FIG. 1 and FIG. 2 , an intelligent sensing terminal and a method for applying the intelligent sensing terminal provided according to a preferred embodiment of the present invention will be described. In this embodiment, the intelligent sensing terminal is used for the intelligent monitoring device, that is, the intelligent sensing terminal and the intelligent monitoring device work together, wherein the intelligent monitoring device includes a plurality of base stations arranged at different positions. It should be noted that the "intelligent sensing terminal used in intelligent monitoring equipment" mentioned in this article refers to that the intelligent sensing terminal can be formed as an independent component and applied to intelligent monitoring equipment, or can work together with intelligent monitoring equipment to form an intelligent sensing terminal. It is a component of intelligent monitoring equipment. The intelligent perception terminal is used for real-time monitoring of hazardous chemicals storage and transportation equipment. The intelligent sensing terminal is installed on the hazardous chemical storage and transportation equipment (specifically, a chemical tank in this embodiment). The intelligent sensing terminal includes a casing and a terminal system fixed in the casing. Preferably, the casing is sprayed with conductive paint, and the intelligent sensing terminal can transmit harmful static electricity to the chemical tank through the casing without shielding the antenna signal of the positioning module, and ground through the chemical tank.
终端系统又包括中央控制单元和用于向中央控制单元供能的供能单元。The terminal system in turn includes a central control unit and an energy supply unit for supplying energy to the central control unit.
在本实施方式中，中央控制单元为基于STM32L1系列芯片搭建的最小系统。本领域的技术人员可以理解，最小系统是指用最少的元件组成的单片机可以工作的系统，其具体结构在此不再赘述。STM32L1芯片可保证智能感知终端的主控系统在低工作电压(可低至1.8V)条件下正常工作。智能感知终端具有可降功耗的功能，即在预定条件下，智能感知终端的至少部分部件能够进入低功耗模式(将在后文详细描述)。在低功耗模式下，智能感知终端的工作电流可低至μA级别。在本实施方式中，智能感知终端系统具体包括CPU、定位模块、存储器、无线通信模块以及数据采集模块。In this embodiment, the central control unit is the smallest system built on the basis of STM32L1 series chips. Those skilled in the art can understand that the minimum system refers to a system in which a single-chip microcomputer composed of the fewest components can work, and its specific structure is not repeated here. The STM32L1 chip can ensure that the main control system of the intelligent sensing terminal works normally under the condition of low operating voltage (can be as low as 1.8V). The intelligent sensing terminal has the function of reducing power consumption, that is, under predetermined conditions, at least some components of the intelligent sensing terminal can enter a low power consumption mode (which will be described in detail later). In the low power consumption mode, the operating current of the intelligent sensing terminal can be as low as μA level. In this embodiment, the intelligent sensing terminal system specifically includes a CPU, a positioning module, a memory, a wireless communication module, and a data acquisition module.
其中，定位模块与服务基站和附近基站通信并获取来自各个小区的数据(该数据具体包含：服务小区和邻近六个小区信息提示；载波列表和BA内的测量频点列表)。定位模块使用移远M35模块实现，CPU发出控制指令至定位模块，定位模块将所获取的数据传递至CPU，CPU对所获取的数据进行处理。最终，中央控制单元将处理后的数据通过无线通信模块发送至平台，平台对数据进行解析、筛选、定位查询、信息显示等操作。The positioning module communicates with the serving base station and the nearby base stations and obtains data from each cell (the data specifically includes: the serving cell and six neighboring cells information prompts; the carrier list and the measurement frequency point list in the BA). The positioning module is realized by using the Quectel M35 module. The CPU sends control commands to the positioning module, and the positioning module transmits the acquired data to the CPU, and the CPU processes the acquired data. Finally, the central control unit sends the processed data to the platform through the wireless communication module, and the platform performs operations such as analysis, screening, positioning query, and information display on the data.
优选地，定位模块构造为采用多基站混合定位算法进行计算。同样优选地，定位模块包括GSM/GPRS模块。在作业中，CPU下发获取定位信息的指令，M35响应指令，并搜索附近基站，建立网络链接，然后获取关于服务小区和附近至多六个小区的提示信息，并回传CPU。同理，CPU发出获取时间指令，M35响应指令，获取时间数据包，并回传至CPU。Preferably, the positioning module is configured to use a multi-base station hybrid positioning algorithm for calculation. Also preferably, the positioning module includes a GSM/GPRS module. During the operation, the CPU issues an instruction to obtain positioning information, and the M35 responds to the instruction, searches for nearby base stations, establishes a network link, and then obtains prompt information about the serving cell and up to six nearby cells, and sends it back to the CPU. In the same way, the CPU issues a time acquisition command, and the M35 responds to the command, acquires time data packets, and sends them back to the CPU.
为了使CPU能够更高效更具针对性地进行数据处理，CPU还内置有数据处理模块。数据处理模块对M35回传的提示信息进行拆包、解析、提取信息和重组数据等操作，构成能够让平台识别的，并能查询到位置的数据包。数据处理模块还有智能纠错功能：判断M35回传CPU的数据是否有误，并标志；在建立网络链接失败时计算实时时间，写无网络标志并保存至本地存储器；在建立网络链接成功时，更新时间，并将本地存储的定位信息、定位时间、设备唯一标识号和电池电量等数据发送至平台。In order to enable the CPU to process data more efficiently and more specifically, the CPU also has a built-in data processing module. The data processing module performs operations such as unpacking, parsing, extracting information and reorganizing the data returned by the M35 to form a data packet that can be identified by the platform and the location can be queried. The data processing module also has an intelligent error correction function: to judge whether the data sent back to the CPU by the M35 is wrong, and mark it; when the establishment of the network link fails, calculate the real-time time, write the no network mark and save it to the local memory; when the establishment of the network link is successful , update the time, and send data such as locally stored positioning information, positioning time, device unique identification number and battery power to the platform.
下面对本实施方式的供能单元进行详细描述。The energy supply unit of this embodiment will be described in detail below.
供能单元包括电源和调压模块。调压模块能够对电源输出电压进行调节，以保证中央处理单元的各模块工作电压正常。The energy supply unit includes a power supply and a voltage regulation module. The voltage regulating module can adjust the output voltage of the power supply to ensure that the working voltage of each module of the central processing unit is normal.
