Platform Software Description

Juying Cloud Platform is a network platform software developed by our company, which includes mobile APP platform software and web version platform. The mobile APP software includes two categories: Android and IOS. The platform is designed for our company's DAM series network version devices and GPRS version devices, aiming to provide users with remote control output (relay, switch quantity), analog quantity (4-20mA, 0-10V, 0-5V) acquisition, switch quantity acquisition and other services, greatly facilitating user needs. The server is provided by our company, and customers can use it with confidence.

Working mode description

Non lock linkage mode of this machine

The board module itself has optocoupler input and relay output. In this mode, the input optocoupler and relay are directly linked. Namely: the optocoupler input signal takes effect ->the corresponding relay is engaged, the optocoupler input signal is cancelled ->the corresponding relay is disconnected.

In this mode, due to mechanical and program delays, there will be a certain delay from the optocoupler input signal to the relay action, but the maximum delay will not exceed 0.05 seconds.

Due to the fact that all relays are directly linked by optocouplers in this mode, there may be a phenomenon where the serial port cannot operate the relay. This is not an abnormal phenomenon, but rather a situation where the relay is linked by the optocoupler before it is activated after being operated through the serial port.

Local self-locking linkage mode

The module itself is a board module with optocoupler input and relay output. In this mode, every time the optocoupler inputs a signal, the corresponding relay flips once. Namely:

The optocoupler input signal takes effect ->the relay flips (switch from engagement to disconnection, switch from disconnection to engagement);

The optocoupler input signal is cancelled ->the relay does not operate;

This mode also has the delay issue of non lock mode, but the delay time will not exceed 0.05 seconds.

This mode can mainly be used in situations where external signals are triggered to control the start and stop of equipment, such as when an optocoupler is connected to a button and the corresponding relay is connected to an electrical device. Each time the button is pressed, the device will switch between start and stop states.

Introduction to the Flashing and Breaking Function

Manual mode: For each operation of the relay, the relay will flip once (open when closed, close when open);

Flashing mode: For each operation of the relay, the relay will close for 1 second (actual time [unit second]=set number * 0.1) and then automatically disconnect;

Flashing mode: For each operation of the relay, the relay will disconnect for 1 second (adjustable time) and then automatically close;
