Background
At present, there are two main methods for collecting hydrological information of counties, cities and districts by hydrological and meteorological centers in each region: one is that each hydrological observation station sends hydrological information in a voice mode through a fixed telephone. The hydrologic information transmission method has the advantages that: because the fixed telephone network is adopted to transmit the message in a voice mode, the requirements on each observation station and a water regime observation information operator are low, and the method is suitable for the actual situation of the current observation station. However, the disadvantages are: the water regimen information can only be sent in a voice mode, so that the error code rate is high, and timely and accurate transmission of the water regimen information is difficult to realize. In addition, special staff is required to be equipped in each local hydrological and meteorological bureau, hydrological information received by the telephone is manually compiled into a standard hydrological information message code according to a hydrological information coding standard issued and implemented by the water conservancy department in 2005, and then the standard hydrological information message code is transmitted to the previous-stage hydrological and meteorological bureau. Time-consuming, labor-consuming and low-efficiency.
The other method is as follows: hydrologic information is transmitted by a hydrologic information transmission apparatus. The biggest disadvantages of such a hydrologic information transmission device are: the operator is required to be trained professionally and skillfully master the hydrologic information coding standard issued by the ministry of water conservancy in 2005, so that the hydrologic information transmission equipment can be used for inputting the hydrologic information message of the day and transmitting the observed hydrologic information. Because of wide territory of China and uneven culture levels of flood reporting personnel of the water conditions in various places, it is difficult for each hydrologic information observer to skillfully master message writing rules to write hydrologic information messages, and the hydrologic information transmission equipment is used for transmitting hydrologic information, so that the application range of the hydrologic information transmission equipment is narrow.

As shown in FIG. 3-1, in this embodiment, the hydrologic information data transmission terminal control circuit of the present invention employs a W925E/C240A chip developed by Winbond corporation as a microprocessor. The microprocessor is an 8-bit highly integrated microcontroller, the working voltage is 2.2-5.5V, the working modes of the double-crystal oscillator (3.58MHz and 32.768kHz) are 100 pins, and QFP packaging is adopted. Its internal resources are rich, and it has 256K bytes E2PROM, 8K bytes on-chip RAM (accessed by MOVX), 5 groups of I/O ports, 11 interrupt sources, 1 13/14 bit frequency dividers, 1 comparator, 1 watchdog and 2 13/16 bit timers, and 65 Special Function Registers (SFR) for controlling and implementing various functions of the chip.

In order to ensure that the transmitted and received messages are not lost when the hydrologic data transmission terminal is powered off, as shown in fig. 3-2, a Flash memory manufactured by Negaewin company is adopted in the embodiment. Meanwhile, in consideration of the number of messages to be stored, a memory with the memory space of 1Mbit and the model of MM36SB010 is adopted.

The hydrological information data transmission terminal adopts alternating current and direct current as backup power supply, and effectively solves the problem of message transmission when power supply in remote rural areas is difficult. On a hardware system, a lightning surge protection technology is also adopted at the signal input end of the telephone voice communication circuit, and the lightning protection function of the hydrological information data transmission terminal is added.
In order to enable the hydrological information data transmission terminal to be widely applied to each basic hydrological observation station, the operation is simpler, the requirement of operators on learning a complex rule for compiling standard hydrological information messages is met, the hydrological information can be directly input according to prompts, and a standard hydrological information message is automatically generated; meanwhile, in the processes of recording, transmitting and receiving, the transmission error rate of the message is reduced to 0 through a three-level checking mechanism; after the message is edited, a real-time translation function can be provided, and the occurrence rate of false reports caused by human factors is reduced.
A. Firstly, a data dictionary for compiling the hydrological information message is established, and the encoding rule of the hydrological information message is defined.
The data dictionary is established according to a hydrological information coding standard issued and implemented by the water conservancy department in 2005, and Chinese hydrological information elements listed in the hydrological information coding standard correspond to standard message codes thereof one by one.
The hydrologic information message coding rules comprise index rules, message formats, message elements, information numerical ranges input by hydrologic informants and the like between Chinese hydrologic information elements and corresponding message codes.

Translating the input Chinese hydrological information into a standard hydrological information message according to a data dictionary; checking whether the compiled message elements correspond to Chinese hydrological information input by an operator according to a data dictionary, and detecting whether the message is correct so as to ensure that the message is correctly encoded; if not, returning an error prompt to prompt for re-operation; if so, the next step is performed.
F. Transmitting the hydrological information message according to the selected message transmission mode, and performing parity check on the message in the transmission process; if the message is found to be wrong, retransmitting the message; if the message is correct, the next step is executed.
G. After receiving the hydrologic message, the hydrologic receiving center checks the received message elements again according to the data dictionary, checks whether the received message is correct, and sends out error prompt information if the received message is wrong.
The following describes in detail how the hydrological information data transmission terminal of the present invention implements the above method with reference to the accompanying drawings.
As shown in fig. 5, five control modules are stored in the hydrological information data transmission terminal microprocessor of the present invention: the system comprises an operation control module, a report simulating control module, a transmission control module, a report translating control module and a telephone control module.
The operation control module is a core control module of the hydrological information data transmission terminal and is responsible for interaction and control among the modules. The user can select the required function (such as fig. 6-1 to 6-4) through the menu, and the operation control module is responsible for starting the corresponding processing module according to the selected menu; meanwhile, monitoring incoming call information is also a main function of the control module, and whether central connection is achieved or not is judged according to the incoming call number, so that whether the telephone control module or the transmission control module is started is determined. The user can start the translation and report module and the report module by selecting the menu.
The operation control module detects the keyboard event and the call signal of the PSTN network in real time. In a standby state, after a [ to-be-reported ] key pressing event is received, a to-be-reported control module is started, and when other key information is received, a telephone control module is started. And when the incoming call of the information center is detected, starting the transmission control module. The specific process comprises the following steps:
as shown in fig. 7, in the standby state, if the [ to-be-reported ] key is pressed, the to-be-reported control module is started; if the key is other standard number key, the telephone control module is started. When the terminal is in a certain working state, the control module transfers the control right of the key event to the current working module.
The microprocessor decodes the DTMF and FSK signals and translates the DTMF and FSK signals into binary information codes, and the master control module receives the information codes from the microcontroller in real time according to a system clock. As shown in fig. 8, when the hydrological information data transmission terminal of the present invention is in a standby state, the operation control module waits for the incoming call number of the calling party, and if the number is the number of the receiving center, the transmission control module is started, otherwise, the telephone control module is started. When the transmission control module is in operation, the control module transfers the processing right of the information to the transmission control module.
The simulation report control module provides an interactive simulation report function of the message, is responsible for acquiring the water regime information and codes the water regime information into a message format. And controlling the acquisition sequence of the information according to the water regime rule, and simultaneously combining a specific observation result to realize the control of the interactive process. After the whole message is edited, the message translation control module is started to verify the input observation value, and the message transmission control module can also be started to transmit the information to the information center.
As shown in fig. 6-1, the present invention provides three hydrological information reporting modes for operators to select: and prompting the hydrological information to be reported according to a menu, simulating the hydrological information to be reported according to an example text format stored in the terminal, and manually and directly inputting a hydrological information message.
The report process is described below by taking the case of prompting the report hydrological information according to the menu, and the specific flow is shown in fig. 9:
1. firstly, according to the index information of the message rule selected by the user, the control information to be reported is imported from the flash memory into the memory.
2. Displaying prompt information in the rule, such as prompting to input an observation site code (figure 10-1), observation time (figure 10-2), daily precipitation (figure 10-3) and the like, after a user inputs an observation value, checking the input value (namely, checking for the first time) according to the attribute description in the message coding rule, and if the input value does not meet the attribute requirement, refusing to accept the input; in the rule control information, a condition jump control module can be defined, and when an observed value input by a user meets a jump condition, an interactive flow can be relocated to a specified position in a rule, so that the control of the interactive flow is realized, and the definition of the rule is simplified.
3. When the input observation value is legal, the codes corresponding to the input hydrological factors (hydrological information) are read from the data dictionary according to the code indexes in the message coding rule, and the codes are automatically combined into one part of the hydrological information message.
4. When the user presses the 'end' key, the combined message segments are combined, and the beginning information and the end information of the message are added to form a complete message.
When a complete message is compiled, the hydrologic information data transmission terminal can completely display the proposed message, as shown in fig. 10-5, for verification of a user. At this time, the user may select to start the translation module, perform decompilation on the message (as shown in fig. 10-4), confirm whether the message is correct, or directly select to start the transmission control module, and transmit the message to the information center.
In the process of the report simulation, a user does not need to input any message code, and can perform the report simulation only by inputting the actual observation value according to the prompt, which is one of the main innovation points of the invention.
The transmission control module is responsible for controlling message transmission and receiving control instructions between the hydrological information data transmission terminal and the hydrological receiving center. In the process of inputting and transmitting to receiving messages, the transmitted messages are subjected to triple check including check during inputting, parity check during transmission and check at a receiving end, so that the situation of false report is avoided in the process of simulating report and transmitting. When receiving the data packet sent by the hydrologic center, verification is also performed to ensure the correctness of the received data packet.
The triple check includes:
1. when the Chinese hydrological information is recorded, firstly, whether the Chinese hydrological information recorded by an operator is correct (legal) is checked, then, whether message elements formed by automatic translation of the hydrological information data transmission terminal correspond to the Chinese hydrological information recorded by the operator is checked according to the data dictionary, and whether the message is correct is detected, so that the message coding is correct.
Because the data dictionary is solidified in the data transmission terminal and includes the information of all message elements, the consistency between all element codes in the message and the Chinese input information can be checked according to the data dictionary, and the correctness of the message coding content is ensured.
In addition, the message coding rule is also solidified in the digital transmission terminal, so that the validity check can be carried out on the information and the observed value input by the operator according to the characteristics of each element, and the occurrence of artificial false reports is reduced to the greatest extent in the initial editing stage of the message.
2. During transmission, parity check is carried out on the transmitted message.
And finally setting a checksum for each message coding data packet.
The message information data format is as follows:
| 1B | 1B | 1B | <＝254B | 1B | |
| synchronous lead-through string | Type of information | Information length | Information serial number | Information content | Checksum |
Synchronous guide string: the sync leading string consists of two parts, the first part consisting of a set of 80 consecutive alternating bits of "0" and "1", and the second part being a sync ending string consisting of 20 consecutive "1". After reading at least 50 alternating bits of "0" and "1" and 10 "1" s, synchronization can be considered established.
The information type is as follows: indicating the type of information content
Information length: the information length refers to the sum of the information sequence number and the byte number of the information content of the message layer
Information sequence number: the information sequence number may uniquely identify a packet.
Information content: containing message content and other ancillary information
And (4) checking the sum: for error detection of data transfer procedures. Taking values: the sum of all bytes in the packet, except the sync leader, is modulo 256 and complemented to obtain the value.
For example, if a calculated checksum of "1" indicates error, a "0" indicates correct.
3. After receiving the message, the hydrologic center verifies the message
After the message is transmitted to each hydrological center, the central computer firstly carries out comprehensive inspection on the format and each element of the message to ensure the legalization of the message content.
And meanwhile, checking the submitted numerical value according to the limit value data of each testing station, and refusing to receive the message when receiving abnormal data. To ensure the correctness of the message.
As shown in fig. 11, the specific flow of transmitting the hydrologic information message is as follows:
1. firstly, reading the message from the message storage area to be sent to the memory.
2. Checking whether the compiled message corresponds to hydrological information input by an operator according to the data dictionary, detecting whether the message is correct, and executing the following steps after the verification is passed; after the error is detected, carrying out error prompt and reading the next message to be sent;
3. determining whether to divide the information into a plurality of data packets for transmission according to the length of the information; and setting transmission parity check bits of the message data transmission packet.
The information content is packaged into one or more data packets, the data packets contain information such as the length, index and the like of the information, and meanwhile, the check code is stored in the last byte of the data packet.
4. Establishing connection with a hydrological receiving center, transmitting a data packet to the center, then waiting for data packet receiving result information fed back by the center, if the data packet is normally received, transmitting the next data packet, if the transmission is wrong, repeatedly transmitting the previous data packet for at most three times, if all the data packets fail, terminating the transmission, and displaying error information.
5. After receiving the message, the hydrologic receiving center checks whether the message is correct and complete again according to the data dictionary, if the message is complete and correct, the information of normal receiving is returned, otherwise, the information of wrong receiving is returned.
6. And finishing the connection between the hydrological information data transmission terminal and the hydrological receiving center, and displaying the message sending condition.
When the hydrologic information data transmission terminal of the present invention receives the data packet sent by the hydrologic center, it also needs to check whether the received data packet is complete and correct, and the specific flow is shown in fig. 12:
1. receiving a data packet (information packet) sent by a hydrological center;
2. calculating a check value of the data packet, and judging whether the check value is the same as the check bit;
3. if the check bits are the same, successful information is fed back to the center, and if the check bits are wrong, failed information is fed back to require retransmission.
4. When a subsequent data packet is needed, the next data packet of the center is waited. And after all the data packets of the whole message are received, combining the messages in all the data packets to generate a message, and storing the message in a message receiving storage area.
The user checks the received message by opening the inbox, and simultaneously can start the translation control module to translate the message and check specific water regime information.
The message translation control module translates the message according to the data dictionary, namely, according to the code of the water regime element, Chinese description of the water regime element is searched in the data dictionary, and information contained in the message is displayed in a picture in a Chinese mode as shown in figure 10-4 for a user to confirm.
The specific flow is shown in fig. 13:
1. firstly, according to the message storage area which is specified by the user and needs to be translated and the index information of the message. And pouring the message content into the memory from the flash memory.
2. Each pair of information code and observation value is resolved from the message.
3. Finding out Chinese information corresponding to each information code according to the digital dictionary;
