Embodiment 1

[0032] Such as figure 1 As shown, the concentrator of the remote meter reading system in this embodiment includes a GPS module 1 , a control module 2 and a time module 3 .

[0033] After the concentrator terminal powers on and completes the initialization work, the GPS module 1 is initialized. After the initialization is completed, the GPS module 1 sends a standard NMEA0183 protocol sentence to the control module 2, and the control module 2 The standard NMEA0183 protocol sentence can be parsed to obtain UTC time, and the UTC time can be converted to local standard time (such as Beijing time), and the local standard time can be written into the EEPROM in the RTC of the time module 3 for time calibration. In this way, it can ensure that the time provided by the concentrator is accurate and reliable, and there will be no error in time measurement, which provides a guarantee for the new type of time-sharing billing and other time-related electricity statistics and cost calculation...

Embodiment 2

[0044] Such as figure 1 As shown, the concentrator of the remote meter reading system of this embodiment also includes a GPS module 1 , a control module 2 and a time module 3 . Such as figure 2 As shown, the remote meter reading system of this embodiment also includes the concentrator, an external master station system and multiple collectors.

[0045] The difference between this embodiment and Embodiment 1 is: in this embodiment, the control module 2 also obtains the longitude information and latitude information of the concentrator by analyzing the standard NMEA0183 protocol sentence, and the longitude information and the latitude information Sent to this external master system for positioning.

[0046] The standard NMEA0183 protocol sentence all has longitude information and latitude information for positioning. After the control module 2 parses the protocol sentence, it can obtain the longitude information and latitude information of the concentrator, and send the longi...

Abstract

The invention discloses a remote meter reading system, a concentrator and a time service method. The concentrator comprises a GPS (Global Positioning System) module, a control module and a time module, wherein the GPS module is used for sending a UTC (Universal Time Coordinated) to the control module, the control module is used for converting the UTC into a local standard time, and writing the local standard time into the time module to correct time. The time correction and positioning of the concentrator can be carried out on the basis of a GPS, the accuracy and reliability of time provided by the concentrator can be guaranteed, timing can not have errors, thereby providing guarantee for power counting and charge calculation relating to time, like novel time-sharing charging, enabling system maintenance personnel to be capable of accurately arriving the place where the faulted concentrator is installed in time, and guaranteeing the equipment maintenance speed and efficiency.

Description

technical field [0001] The present invention relates to a remote meter reading system and its concentrator and timing method, in particular to a concentrator of a remote meter reading system capable of performing timing and positioning functions based on GPS, and a remote meter reading system including the concentrator And a timing method implemented by the concentrator. Background technique [0002] With the rapid development of my country's national economy and the rapid improvement of people's quality of life, the society's demand for electricity is also increasing. However, the current management of residents' electricity consumption is still very backward. For many years, the traditional operation method of first using electricity, then reading meters, and then paying for residents' electricity consumption management has been adopted. However, the manual meter reading method has low work efficiency and high labor intensity, and there will be problems such as incomplete...
