Description

Technical Field

[0001] The present invention relates to the technical field of power line communication, and in particular to a multifunctional STA module testing method and equipment based on main control platform software. Background Art

[0002] In order to realize the construction of smart grid, it is necessary to remotely read the smart meters such as smart electricity meters, smart water meters, smart gas meters in the low-voltage power distribution network, so as to monitor and manage the users' electricity, water and gas consumption in real time. At present, the communication modules used in the low-voltage power distribution network are divided into two categories: single-mode and dual-mode. The single-mode mainly includes the two solutions of HPLC carrier and micro-power wireless RF, and the dual-mode mainly includes the two solutions of HPLC / RF dual-channel single network and HPLC / RF dual-protocol stack dual network.

[0003] HPLC carrier is a technology that uses power lines as a communication medium. It has advantages such as wide coverage, strong anti-interference ability, and low cost, but it also has disadvantages such as signal attenuation, low transmission rate, and incompatibility with other communication methods. Micropower wireless RF is a technology that uses radio waves as a communication medium. It has advantages such as high transmission rate, good compatibility, and easy expansion, but it also has disadvantages such as small coverage, susceptibility to interference, and high power consumption.

[0004] HPLC / RF dual-channel single network is a technology that combines HPLC carrier and micro-power wireless RF. It mainly uses HPLC carrier for communication. When the HPLC carrier signal is interfered, it uses micro-power wireless RF for forwarding to improve the reliability of communication. However, this technology only supports HPLC protocol and does not support standard micro-power wireless protocol. Therefore, it cannot be interconnected with the original micro-power wireless equipment. All micro-power wireless equipment needs to be replaced, which increases the difficulty and cost of construction.

[0005] HPLC / RF dual protocol stack dual network is a technology that uses HPLC carrier and micro-power wireless RF as two independent communication networks. It supports HPLC protocol and standard micro-power wireless protocol, and can be interconnected with existing micro-power wireless devices to achieve communication compatibility. However, due to the small coverage of micro-power wireless RF, this technology leads to incomplete micro-power wireless network construction, and cannot realize meter reading of all micro-power wireless devices, which reduces the integrity of communication.

[0006] In order to solve the shortcomings of the above-mentioned prior art, some new communication schemes have been proposed, such as a meter reading system with mixed HPLC and micro-power wireless devices disclosed in a Chinese patent (patent number CN202111548739.2, patent name: A meter reading system and method with mixed HPLC and micro-power wireless devices), which includes an HPLC central coordinator (CCO), an HPLC single-mode module (STA1), an HPLC / RF dual-mode module (STA2) and an RF single-mode module (STA3), wherein the HPLC / RF dual-mode module (STA2) has the function of forwarding data between the standard HPLC protocol and the standard micro-power wireless, and can realize the intercommunication between the HPLC carrier and the micro-power wireless RF, thereby realizing the meter reading of all meters and improving the compatibility and integrity of communication.

[0007] However, this solution also has some problems. The data forwarding function of the HPLC / RF dual-mode module (STA2) may cause signal interference between the HPLC carrier and the micro-power wireless RF, reducing the stability and reliability of communication. The data forwarding function of the HPLC / RF dual-mode module (STA2) may increase the power consumption and heat generation of the system, affecting the life and performance of the module, which may easily cause the failure of the STA module and make it difficult to detect and troubleshoot in time. To this end, we propose a multifunctional STA module testing method and equipment based on the main control platform software. Summary of the invention
