Embodiment Construction

[0018] In this specific embodiment, the maximum effective pulse width of the standard pulse output signal of the sixteen-channel pulse meter that can be simulated output is 80ms, and the cycle has four options: 160ms, 500ms, 1s, and 5s;

[0019] You can choose to send out standard pulse signals regularly, and you can choose five options: 1 hour, 5 hours, 10 hours, 24 hours, and real-time sending; you can choose 500, 1,000, 10,000, 100,000, and 250,000.

[0020] An optional interfering pulse signal can be added to the standard pulse signal.

[0021] It can simulate the pulse meter signal to send out fault phenomena such as open circuit and short circuit;

[0022] 220VAC or 24VDC power supply can be selected;

[0023] like figure 2 As shown, the resistance parameters of the analog pulse generating circuit: R8, R9, R10 are 3KΩ, R12 is 22KΩ, R15 is 2KΩ.

[0024] The analog pulse generating circuit can simulate a household pulse meter, continuously timing or quantitatively send...

Abstract

The invention discloses a standard pulse generator to analog user pulse metering list to connect data collector based on pulse gathering technique, which comprises the following parts: MCU, LCD screen, keyboard, I-to-O port expanding circuit, rapid light coupling relay to switch two output resistant signals, analog pulse happening circuit to provide resistant network of two output resistances to output analog pulse signal. The invention can send sampling period and non-source pulse signal with different duty cycles continuously and timely or quantitatively and analogs the short-cut of pulse metering list, which satisfies the testing need of national standard GB / T 20866-2007 'data collector based on user pulse metering list'. The invention can test the metering property under experiment oron-site environment for data collector effectively, which solves the metering accuracy to test the data collector.

Description

technical field [0001] The invention relates to the detection and verification of a core equipment data collector of an automatic meter reading system, in particular to a standard pulse generator capable of simulating a household pulse meter. Background technique [0002] As the main core equipment of the automatic meter reading system, the data collector based on the pulse acquisition technology is widely used in the automatic meter reading charge management of household meters, and has gradually become the mainstream of the meter reading industry. However, there is no similar standard pulse generator at home and abroad that can simulate pulses sent by household pulse meters, which makes it impossible to verify the accuracy of the data collected by the data collector. Contents of the invention [0003] The technical problem to be solved by the present invention is to make up for the defects of the above-mentioned existing analog measurement technology, and to propose a st...
