the water sucking port of the fire pump is connected with the water sucking pipe of the deep well (2) of the analog digital display test through a water sucking pipe (8) and is connected with a fire-fighting quick connector to finish the pipeline connection of detecting water sucking of the fire engine, and a pressure sensor (3-1) and a pressure gauge (3-2) are additionally arranged on the water sucking pipeline and are respectively used for measuring the vacuum pressure of the water sucking port; the water in the deep well (2) of the analog digital display test is pumped into the pipeline of the detection system by the fire pump through the fire hose (7), the number of the quick-connection fire-fighting connectors is 2 or 4 according to the difference of various vehicle types, the inspection and measurement system (3) is respectively provided with 4 quick-connection fire-fighting connectors in the middle, low and high pressure pipelines so as to be suitable for the detection of various fire vehicle types, and the inspection and measurement system (3) is respectively provided with an electric flow regulating valve, a turbine flowmeter, a pressure sensor (3-1) and a pressure meter (3-2) on the middle, low and high pressure pipelines so as to be respectively used for regulating the flow of the pipeline of the measurement system and the pressure and the flow of the measurement pipeline; the water of the high, medium and low pressure water pipes of the measuring system finally flows back into the analog digital display test deep well (2) through the pipeline, so that the cyclic utilization of the fire water is realized, the water depth is kept in the specified range of the detection standard, the analog digital display test deep well (2) ensures that the water of the well is always kept in the specified range, and once the water level is lowered, the system starts the submersible pump positioned in the automatic detection fire water tank (1) to quantitatively supplement water;
the method comprises the steps of:
1) The control circuit and the communication loop are correctly connected, and the control circuit and the communication loop are carefully checked;
2) Debugging control system hardware, setting basic parameters of a secondary instrument, enabling the system to work in an optimal state, and performing test operation to test whether parameter setting is correct or not;
3) The upper computer is connected, and the upper computer software is debugged, so that the whole system is in an optimal working state;
4) Entering an upper computer working interface, then switching on a temperature control system power supply to enable the system to start to work normally, and recording various parameters of the system operation in the upper computer in real time;
5) Checking various parameters in the running process of the system at any time through various interfaces of the upper computer;
6) During the running process of the system, the monitoring program is not exited, otherwise, some data are lost;
7) When the system runs stably or the data does not need to be recorded, the monitoring program is exited;
8) After the whole program is completely run, the whole running process can be checked in an upper computer, required data are recorded or printed in a historical report or a historical trend, and snapshot photos generated in the running process are subjected to post-processing in corresponding software;
9) And drawing a trend chart in the total operation trend chart according to the recorded data, generating various reports and graphs, printing according to requirements, and storing corresponding operation data.
