An uplink and downlink communication test device for a power consumption information collection terminal

Abstract

The invention relates to an upward and downward communication test device of a power consumption information collecting terminal. The upward and downward communication test device is mainly formed in a way that a wireless communication test device and a carrier communication test device are respectively connected with a computer system. The wireless communication test device is used for being connected with an upward communication interface of a power consumption information collecting terminal to be tested, and the carrier communication test device is used for being connected with a downward communication interface of the power consumption information collecting terminal to be tested. The wireless communication test device consists of an 8960 communication comprehensive test device, a 9010a signal analysis instrument and a radio frequency switch, and the carrier communication test device consists of two LISN (line impedance stabilization network) power supplies, a receiver, a gating switch, a wireless router, a serial port communication server, a 485 communication switch and a controlled attenuator. The device has the advantages that the detection on the communication capability and the index of a GPRS (general packet radio service) channel and a carrier channel of the power consumption information terminal to be tested is automatically controlled through the computer system, the real-time, accurate and reliable basis is provided for the operation of the power consumption information terminal, and the normal and safe operation of the power consumption information terminal is ensured.

Description

technical field [0001] The invention relates to a testing device for an electrical information collection terminal, in particular to a device capable of detecting the communication capabilities and indicators of the uplink communication information (GPRS communication channel) and downlink communication channel (low-voltage power line carrier communication channel) of the electrical information collection terminal. Background technique [0002] The power consumption information collection terminal used in the field undertakes the data collection and data upload functions of the electric energy metering device. The commonly used uplink communication adopts the GPRS communication method, and the commonly used downlink communication adopts the low-voltage power line carrier communication method. Since GPRS is a public network communication system, communication The mechanism is extremely complex, and the low-voltage power line carrier communication test environment is not easy t...

[0002] The power consumption information collection terminal used in the field undertakes the data collection and data upload functions of the electric energy metering device. The commonly used uplink communication adopts the GPRS communication method, and the commonly used downlink communication adopts the low-voltage power line carrier communication method. Since GPRS is a public network communication system, communication The mechanism is extremely complex, and the low-voltage power line carrier communication test environment is not easy to build. As a result, the communication test of the power consumption information collection terminal has been unable to be carried out effectively, which has brought a shadow to the validity verification of the collection terminal communication.
