After harvester switches on power, first master controller reads the temporal information in clock controller (DS12C887), and this clock chip internal battery is for the continuing to run with of clock after maintaining power-off. if the tidal level acquisition time (gathering a tidal level in every 5 minutes), start radar sensor and gather tidal level, consider the impact of the wave of sea water, for improving the accuracy gathering data, main controller controls radar sensor gathers tide level data continuous 15 times, radar is closed after the RAM of the temporary CUP of the data collected, 15 groups of data will be collected process, processing method be remove respectively in 15 groups of data maximum and minimum, and other 13 groups of data are obtained current tide level data as arithmetic mean, such in order that improve the accuracy of tide level data. then the related data of meteorological sensor and visibility sensor is gathered, and by the data compilation of above-mentioned collection, the supply voltage of last master controller detection storage battery, and the behaviour in service information of battery voltage is stored in the SD card of SD card memory module with the above-mentioned data put in order together with temporal information, above-mentioned data are sent to DTU simultaneously, DTU data are uploaded to Surveillance center by network.

Keyboard and display are for human computer conversation, and display is used for showing current time (year, month, day, hour, min, second) and tidal level, visibility and weather information, and during normal operation, display is in low-light level for energy-conservation. Keyboard is used for arranging clock.

This instrument application example:

Referring to Fig. 1, whole system is formed the tide level data collection in corresponding sea area by being laid in each tidal station longshore, the tide level data that synchronization timing is collected by each tidal station is sent to wireless base station by existing telecommunication wireless network, again through the monitoring center of network delivery to unit. Such hydrologic management personnel just can easily by computer hydrologic monitoring software real-time monitored to the tidal level at each tidal level station, meteorology and atmospheric visibility situation, and each tidal level station data are stored lane database.

Tidal station is laid on seashore and island, is unmanned during usual normal operation, and power supply (at harbour) can be powered through the DC power-supply system of AC-DC conversion or (island) solar panels and storage battery composition by exchange AC.The tidal observation equipment of tidal station will be gathered the tidal level change information of sea water or processed by data with out of Memory (such as atmospheric visibility and weather information etc.), it is sent to Surveillance center through network, simultaneously and store data in the memorizer of harvester by DTU (wireless communication module). The monitoring personnel of such Surveillance center can understand the situations such as the tidal level of each tidal station in real time by PC or other display, provides relevant information for management accordingly and application. The data storage of harvester is the data backup for gathering, and (DTU goes bad or network paralysis) by tidal level management personnel to field download data, the while that each tidal station being, regularly can carry out data acquisition and return to Surveillance center in real time when needed.

The main purpose of this instrument is to measure tidal level changing condition and relevant meteorology, the visibility information of sea water, corresponding data are supplied to corresponding hydrographic survey and ship's navigation use, if being arranged in the river course in inland useful more significantly of the detection application effect in flood season.

The above-mentioned detailed description this tidal level meteorology integrated acquirer carried out with reference to example, is illustrative rather than determinate, therefore without departing from changing and modifications under this utility model general plotting, should belong within protection domain of the present utility model.
