The collection board is mainly used to collect the water pressure of the fire hydrant to calculate the flow used and the number of times of water use; The acquisition board is powered by lithium battery and can regularly report the power situation to remind the management personnel to replace the battery; The acquisition board can collect water level, water pressure and box opening, and contains a network test button (to test whether the network communication is normal). The acquisition board uses GPRS module and HTTP protocol to communicate with the background.

Function Description:

1. The acquisition board collects an analog quantity (pressure value), and two switching quantities (detecting fire hydrant damage signal and fire hydrant cover opening signal) are uploaded to the server cloud.

2. Data upload conditions of acquisition board:

   a. One analog value and two switching values at the acquisition board end are changed arbitrarily

   b. Arrival upload time period

3. The server can set the period of uploading data from the acquisition board.

4. When the key on the acquisition board is pressed, the LED light flashes to indicate whether the communication is normal.

5. When the system detects insufficient power, it sends alarm information to the server cloud in time.

6. The customer provides the signals of analog quantity and switching quantity and the communication protocol between the server, which is collected by the acquisition system.
