MVME331有两种不同的含义：

MVME331是摩托罗拉的一款全系列板卡。

MVME331是配变终端设备(distributionTransformersupervisoryTerminalUnit)，是用来监测并记录配电变压器运行状况的设备。

MVME-331TTU即配变终端设备(distributionTransformersupervisoryTerminalUnit)，是用来监测并记录配电变压器运行工况，根据低压侧三相电压、电流采样值，每隔1～2min计算一次电压有效值、电流有效值、有功功率、无功功率、功率因数、有功电能、无功电能等运行参数，记录并保存一段时间（一周或一个月）和典型日上述数组的整点值，电压、电流的最大值、最小值及其出现时间，供电中断时间及恢复时间，记录数据保存在装置的不挥发内存中，在装置断电时记录内容不丢失。配网主站通过通信系统定时读取TTU测量值及历史记录，及时发现变压器过负荷及停电等运行问题，MVME331根据记录数据，统计分析电压合格率、供电可靠性以及负荷特性，并为负荷预测、配电网规划及事故分析提供基础数据。如不具备通信条件，使用掌上电脑每隔一周或一个月到现场读取记录，事后转存到配网主站或其他分析系统。

由于只有数据采集、记录与通信功能，而无控制功能，结构要简单得多。为简化设计及减少成本，TTU由配变低压侧直接变压整流供电，不配备蓄电池。在就地有无功补偿电容器组时，为避免重复投资，TTU要增加电容器投切控制功能。

AMR  MVME331即自动抄表系统(AutomaticMeterReading)，是指采用通信和计算机网络等技术自动读取和处理表计数据。发展电能自动抄表技术是提高用电管理水平的需要，也是网络和计算机技术迅速发展的必然。在用电管理方面，采用自动抄表（远程抄表）技术，不仅能节约人力资源，更重要的是可提高抄表的准确性，减少因估计或誊写而造成账单出错，使供用电管理部门能及时准确获得数据信息。电力用户因此不再需要与抄表者预约上门抄表时间，还能迅速查询账单。

The MOTOROLA MVME331 VMEbus Intelligent Communication Controller (ICC) supports six asynchronous serial communication channels with a maximum simultaneous speed of 9600 baud full duplex. The module contains a complete jacket

16-bit microcomputer, package

Includes an MC68010 MPU, 128KB(optional 512KB) of RAM, and 32(firmware in B ROM). The microcomputer controls three Z8530 serial communication devices that preprocess and transmit data between the VME system memory and the serial port.

MVME331 has two different meanings:

The MVME331 is a full range of MOTOROLA board cards.

MVME331 is worthy to terminal equipment (distributionTransformersupervisoryTerminalUnit), is used to monitor and record device of distribution transformer operation.

MVME - 331 ttu distribution terminal equipment (distributionTransformersupervisoryTerminalUnit), is used to monitor and record the distribution transformer operation condition, according to the low voltage side three-phase voltage, current sampling values, Calculate voltage RMS, current RMS, active power, reactive power, power factor, active power, reactive power and other operating parameters every 1 ~ 2min, record and save the whole point value of the above array for a period of time (one week or one month) and typical day, the maximum and minimum values of voltage and current and their occurrence time, power supply interruption time and recovery time. The recorded data is stored in the non-volatile memory of the device, and the recorded content is not lost when the device is powered off. The main station of the distribution network periodically reads the TTU measured value and historical records through the communication system, and timely finds the operation problems such as transformer overload and power outage. According to the recorded data, MVME331 statistically analyzes the voltage qualification rate, power supply reliability and load characteristics, and provides basic data for load prediction, distribution network planning and accident analysis. If the communication conditions are not available, use the PDA to read the records on site every other week or month, and then transfer them to the main station of the distribution network or other analysis systems.

Since there are only data acquisition, recording and communication functions, but no control functions, the structure is much simpler. In order to simplify the design and reduce the cost, the TTU is supplied by direct transformer rectifier on the low voltage side of the distribution transformer, and does not have a battery. In order to avoid repeated investment, the capacitor switching control function of TTU should be increased in the local reactive compensation capacitor bank.

AMR MVME331 is the AutomaticMeterReading system (automatic meter reading), which refers to the use of communication and computer network technology to automatically read and process meter data. The development of automatic meter reading technology is the need to improve the level of electricity management, but also the rapid development of network and computer technology is inevitable. In terms of electricity management, the use of automatic meter reading (remote meter reading) technology can not only save human resources, but more importantly, improve the accuracy of meter reading, reduce the bill error caused by estimation or transcription, so that the power supply management department can obtain data information in a timely and accurate manner. As a result, electricity users no longer need to schedule an on-site meter reading time with a meter reader and can quickly check their bills.
