Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] In the embodiment of the present invention, multiple number list files to be issued are formed by breaking up the numbers to be issued in each area, and the numbers to be issued in the number list files to be issued are formed into queues of numbers to be issued in each channel according to the user weights in each area. And dynamically adjust the SMS sending rate according to the user weight.

Abstract

The invention is suitable for the field of internet control. The invention provides a long-distance test and control device and a system. The system comprises a site test and control device and a programmable controlling device. The site test and control device is used for communicating through a serial port on a controlling device, thus the site test and control are achieved. The programmable controlling device is used for providing service for a site test and control system. Data are collected and analyzed. Problems emerging in the test and control are concluded. The service is provided for the test and control system through the programmable controlling device, thus the long-distance control of the site test and control device is achieved by a general packet radio service (GPRS) communication module. The problems that the field power supply is difficult that a device can not be operated, a remote test and control cable network can not be inserted, remote monitoring is not guarded by anyone, working intensity of staff is large and the like are solved. Operation management automation level and system comprehensive automation level are improved.

Description

technical field [0001] The invention belongs to the field of Internet control, in particular to a remote measurement and control device and system. Background technique [0002] In practical applications, oil fields, municipal engineering (water sources of waterworks, city gas pressure stabilizing stations, etc.), public engineering of large factories (storage and transportation of raw materials or finished products, supply of electricity, heat, water vapor, etc., for scheduling needs, a certain In some factories, it is parallel to the DCS of each workshop and specially designed measurement and control systems), oil and gas pipelines, power grid dispatching, mobile equipment (transportation tools, construction machinery, cranes in large workshops, etc.) adopt monitoring and data acquisition systems and wireless transmission There are many engineering examples using remote terminal units, but because there are many types of related equipment that can be selected recently, fie...
