Problems solved by technology

Therefore, the detection efficiency of the traditional collection terminal detection device is very low, and a large number of manual participation will inevitably bring more uncertain factors into the detection results, affecting the reliability of the detection results
[0004] Moreover, the existing detection device can only carry out the detection of one type of collection terminal at the same time, and cannot detect two types of collection terminals at the same time, and cannot quickly complete the connecting action of two batches of terminals under inspection, which affects the detection efficiency

Embodiment 1

[0067] The accuracy of the counting function of the pulse collection function of the electricity information collection terminal is tested through the pulse volume collection test. In practical applications, in order to adapt to the fact that some electric energy meters do not have 485 meter reading interfaces, the power consumption information collection terminal can calculate the power by counting the pulses sent by the electric energy meter and the pulse frequency, so as to realize power control, and calculate the cumulative value by counting the number of pulses × constant Electric energy, so as to realize electric control. The purpose of the pulse collection test is to test the counting accuracy of the terminal pulse collection function.

[0068] The terminal test equipment inputs a given level pulse to the terminal at the set frequency, and the software calculates the theoretical power P according to the constant of the measurement point, and then reads the actual calcul...

Embodiment 2

[0072] The time period control function of the load terminal (power consumption information collection terminal) is one of the four power control functions. This function can divide a day into up to 8 time periods. Each time period can set the power upper limit, and the trip control signal will be output automatically if the limit is exceeded. .

[0073] The terminal test equipment presets parameters such as the time of day and power limit to the load terminal, and then outputs the set output power to the load, and detects whether the terminal outputs all rounds of trip signals within the specified time. If all round signals are detected, it is qualified, otherwise it is unqualified, the test interface is as follows Figure 10 shown.

[0074] The test steps are as follows:

[0075] 1. The power supply of the control device is turned on and the voltage output is 220V.

[0076] 2. Send commands through the infrared communication interface to set terminal alarms and events to ...

Description

technical field [0001] The present invention relates to electric power information technology, especially information terminal detection technology, and specifically relates to a terminal detection system for collecting electricity information. Background technique [0002] With the construction of the electricity consumption information collection system, various electricity consumption information collection terminals are becoming more and more popular, and the usage is gradually increasing. How to realize high-quality, fast and unified detection of various collection terminals is of great significance. [0003] The traditional collection terminal detection device generally adopts the mode of hanging meter rack with detection equipment, and the detection process requires manual participation. When testing a terminal, it is first necessary to manually hang the terminal to be tested on the frame, and then connect the test line. There are many signal test ports that need to ...
