Mainly comprise the feature of parts:
Described keyboard mainly completes human computer conversation, can complete the setting to present clock, the emptying of data storage, the data that stored by data storage download to computer (PC) etc. by data output (COM).
Described clock controller can use dallas, U.S.A chip companies newly designed clock chip DS12C887, this chip has multiple data memory format, can well meet different clock design requirements, this chip also provides data storage lithium battery for oneself simultaneously, can preserve the clock set in the event of a power failure and work on.
Described data storage is mainly used to preserve the tidal level acquisition data handled well and compress and temporal information, it is considered to the requirement of tidal level detection, needs within 5 minutes, gather a tide level data.Current storage chip has two types, static state and dynamic memory, static storage need not store power supply, use more convenient, but its erasable number of times is typically at 100,000 times (according to chip handbook), within such 5 minutes, gather once, within one day, want 288 times, 1 year will more than 100,000 time erasable, that is within 1 year, will change with static memory, it is clear that it is worthless for using static memory.And dynamic memory is to use storage power supply to keep the data preserved not to be lost in the event of a power failure, although circuit is the most more complex, but without the restriction of erasable number of times.Therefore using in design is dynamic memory chip UT62256, and this chip is 32K memory space, if tide level data and temporal information to gathering carry out data compression, at least can store tidal level and the time data of 50 days.Here the storage data in design data storage method is the current tidal level of at least 50 days the most forward of storage and time data, i.e. memorizer are to store currently and previously 50 days tidal level and time data forever.If the most once data communication failure, as radio communication apparatus damages, tidal level inspection center cannot receive real-time tide level data, has the time to meet staff to field maintenance and the tide level data of the corresponding natural law of download the most completely.
The effect of described main power board is the normal work power supply of storage battery or solar panels carrying out voltage stabilizing to be supplied to instrument, it is to use Switching Power Supply structure that this power panel completes the conversion of DC to DC, so can be greatly improved the conversion efficiency of power supply, be conducive to the use of on-the-spot tidal station preciousness electric energy.Instrument can be operated in the power supply of 9-18V and power; in view of the interference of thunder and lightning when high-frequency electromagnetic interference and thunderstorm produced by large vessel dealing electromotor, circuit of the present invention adds D20 surging prevention diode and electric capacity C20-C23 as anti-low-and high-frequency EMI Filtering.Due to radio communication apparatus running voltage 5-35V, laser sensor running voltage at 9-20V, therefore without voltage stabilizing directly by bridge circuit PD1 output power supply.It is unmanned in view of each tidal station, the behaviour in service knowing storage battery electric energy is critically important, IC21 for this main power board is the service condition for monitoring storage battery electric energy, once storage battery is excessively used, supply voltage low to 10.8V time, can be detected and upload to the master controller of mainboard by IC21, master controller reach Surveillance center by radio communication apparatus, it is simple to the instant maintenance of attendant.
Described master controller (CPU) is the heart of tide register, and the work process of whole tide register has been controlled by.Design can use the AT89C52 single-chip microcomputer of American ATMEL as master controller (CPU), it is the enhancement mode of INTEL Corp. 51 series monolithic, there is software development convenience, emulation easily, and software translating writes the features such as flexible, ram in slice increases to 256 bytes of storage space, and the data facilitating whole equipment process.WATCH is set up in sheet
DOG (house dog) CPU manages circuit, and software programming starts house dog, this makes it possible to control very well owing to interference causes master controller software to run the phenomenon appearance flown and crash.
Gather the clock data exported by clock controller during master controller work and determine whether to start tidal level detection, if it is start laser sensor and carry out tide level data collection, carry out the data collected being temporarily stored in the RAM of master controller after data process arrangement, IC21 to be gathered provides the voltage energy consumption of power supply, it may be judged whether normal.Tide level data in RAM, the temporal information of clock controller and storage battery energy consumption are sent to radio communication apparatus, start radio communication apparatus and data are together passed to Surveillance center.The most also tide level data and temporal information are compressed, store in data storage, and the tide level data in RAM and temporal information are shown on liquid crystal display.
This tidal observation method emphasis is implemented step and is included:
(1) tide level data collection
The key data of tide register is real time tide level data acquisition, uses laser sensor to have data acquisition as tide level data collection accurate, it is not necessary to safeguard advantages such as (for pressure and float-type transmitters).But for wave and the impact surged, tidewater detection accuracy is required more important, when this writes software, the collection correctness to tide level data is extremely important, it is necessary for using digital filtering, the method of current digital filtering substantially has three kinds i.e. program to judge filtering, medium filtering and moving average value filtering, for above-mentioned wave impact, the integrated digital filtering method that the moving average value filtering using program to judge in design and to improve combines is to meet the accuracy of tidewater data acquisition, data acquisition 15 times every time, remove the collection data of minimum and maximum, and to other sampled data moving average value filtering.
(2) watchdog reset
It is unattended during tide register work, the software fully relying on master controller completes voluntarily, it is likely to result in software race to fly (such as thunder and lightning) when suffering external disturbance and crash, in design in addition to installing Anti-surging and filter circuit on hardware additional, is also added into master controller management circuit WATCH
DOG(house dog), common house dog is reset master controller (CPU) after the race of master controller software flies to crash, and the temporal information sampled and tide level data will be stored in data storage by tide register every time, in order to ensure the data storage area domain integrity in memorizer, master controller must be known by the cause that oneself resets, the ram space of a byte is have employed for this as reset breakpoint flag bit in designing, ensure that master controller (CPU) reset routine every time knows it oneself is that starting up resets or watchdog reset when performing, if watchdog reset, program will continue executing with program before reset at breakpoint, ensure that whole equipment works complete.
As it is shown on figure 3, this tidal observation method is embodied as step and includes:
(1) instrument switches on power beginning, first by master controller (IC1
AT89C52) from initializing, the RAM corresponding positions of therein is processed, owing to corresponding position being processed when program runs to each key point, the most once fly owing to interference causes primary controller procedure to run, watchdog circuit also can reset master controller make master controller return at corresponding program fleet to continue executing with, and master controller (IC1) is internal can open this circuit from having only to software design patterns with watchdog circuit.Then to corresponding clock controller (IC4 DS12C887), display (12864ZW), data storage (IC3 UT62256) initializes, and reading the current time information of clock controller IC4, write display also shows that current time (including year, month, day, hour, min, second) carries out data compression write data storage simultaneously.Owing to equipment is to be operated in unmanned, for ensureing equipment reliably working, in case primary controller procedure is run flies to cause deadlock, start watchdog circuit and manage the program fleet controlling master controller.Start clock controller and the interruptive port of keyboard simultaneously, wait corresponding interrupt signal.
(2) clock controller each second once interrupts to master controller application, and master controller obtains reading time data of having no progeny in clock controller, and judges whether to be by the tidal level detection time (needs carried out a tidal level detection in every 5 minutes).If being not required to tidal level detection master controller rewritable display temporal information, showing current time in real time, returning circular wait；If desired carrying out the tidal level detection time then starts laser sensor and carries out tidal level detection；Consider the accuracy of tidal level detection, use continuous 15 startup laser sensors to carry out 15 tide level data collections here.
(3) 15 tidal level detection data are carried out data calculating and process in order to obtain current tide level data accurately.By current temporal information and tide level data and main power board by PN1(2 foot) the storage battery electricity behaviour in service signal that exports is (when battery voltage is less than 10.8V, then storage battery breaks down) together it is sent to Surveillance center by radio communication apparatus, and current time information and tide level data are carried out data compression (data storage IC3 limited storage space) storage in data storage (IC3)；Rewritable display display time and tidal level simultaneously, and return circular wait.
(4) keyboard interrupt entrance is that operator carry out current set of time, or when needing, operator download the tide level data in the past 50 days of data storage (IC3) inner storage with computer by data output, and when needing to empty data, carry out emptying of data storage；During keyboard operation, display shows operation content in real time, returns circular wait after completing.
Work process of the present invention and principle are as follows:
The vertical sea of laser sensor of this instrument is installed on the location-plate of seashore tide gauge well support；After tide register switches on power, first master controller reads the temporal information in clock controller (DS12C887), this clock chip internal battery the continuing to run with of clock after maintain power-off.If the tidal level acquisition time (gathering a tidal level in every 5 minutes), start laser sensor and gather tidal level, impact in view of the wave of sea water, for improving the accuracy gathering data, main controller controls laser sensor gathers tide level data continuous 15 times, the data collected close laser sensor after keeping in the RAM within master controller, 15 groups of data will be collected process, processing method is to remove maximum in 15 groups of data and minimum respectively, and other 13 groups of data are obtained current tide level data as arithmetic mean, such purpose is the accuracy in order to improve tide level data.Then temporal information, tide level data, battery voltage behaviour in service information are sent to radio communication apparatus together, by radio communication apparatus, data are sent to Surveillance center by network, again tide level data and temporal information are compressed, store in data storage, and the data stored in data storage are moved forward one group, the purpose of do so is to ensure that the data deposited in memorizer are the tide level data of currently and previously 50 days forever.Last rewritable display display current time and tidal level.
