Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1 to 6, in an embodiment of the invention, a method for remotely positioning and monitoring a tank truck includes the following steps:
step S100, an intelligent remote transmission terminal is arranged in the tank truck, and the actual position of the tank truck is obtained through a built-in Beidou positioning module, so that position data are obtained;
step S200, based on the position data, accessing a 4-20 mA meter signal on site to obtain meter related information including pressure, temperature, liquid level and vacuum degree to obtain meter data;

step S500, based on the real-time radio frequency data, standard data are obtained, and after analysis, the position and the instrument parameter condition of the tank truck are restored to obtain real-time data;
step S600, based on the real-time data, the data content is sent from the cloud server to the user terminal according to a preset mode for the user to view. The user provides a terminal for viewing, and the terminal comprises a computer WEB, a mobile phone applet and the like.
In practical use, the tank truck occupies an important position in transportation, and the transportation of the tank truck is dangerous, so that the related parameters of the tank truck are generally required to be monitored. However, the meter data can be only checked by the tank truck driver, and the driver cannot pay attention to the value and the change of the meter all the time because the driver needs to drive. Meanwhile, by a monitoring mode of transmitting data, the operation is complicated, and the delay of the data in the receiving aspect is relatively large. The tank truck remote positioning monitoring of the invention well solves the current situation. And through the transmission of the radio frequency signals, the cloud server analyzes to obtain the tank car positioning and tank car instrument data, and then the tank car positioning and the tank car instrument data are transmitted to the user side in a preset mode, so that the method is more rapid and convenient. For example, the tank truck positioning and meter parameters can send out radio frequency signals in a specific frequency band, and after receiving the radio frequency signals, the cloud server analyzes the radio frequency signals to obtain specific tank truck positioning and tank truck meter data and sends the specific tank truck positioning and meter data to the user side in a preset mode.
As a specific implementation mode, a solar panel is arranged on the tank truck, solar energy is absorbed and converted into electric energy to be stored, and the electric energy is obtained to supply power for the intelligent remote terminal;
the instrument data are displayed on a panel of the intelligent remote terminal in real time, and the unit, the measuring range and the alarm value of the instrument are set through instrument keys, so that instrument setting data are obtained;
based on the instrument setting data, when the instrument data exceeds an alarm value, an alarm signal is sent out to remind the tank truck to stop running immediately, corresponding measures are taken, and the alarm signal is synchronously uploaded to the cloud server.
In practical application, in order to save energy and protect environment, the intelligent remote transmission terminal of the tank truck for transmitting signals adopts solar energy to supply power, and the tank truck is outdoors in transportation and meets the use conditions of the solar panel. The most directly affected person is the driver in the case of tank truck danger caused by the change of the related parameters of the tank truck. Therefore, the panel is arranged to display the related data of the tank truck detected by the tank truck instrument, and the transportation state of the tank truck is obtained. For example, the unit and the measuring range of the parameters can be adjusted through keys on the panel, so that the habit of watching data of a driver is met. By setting the alarm value, when the parameters of the tank truck reach the alarm value, the alarm can be immediately given to remind the driver.
Referring to fig. 2, according to real-time radio frequency data, the surrounding environment of the location of the tank truck is obtained, the interference of the environment on radio frequency signals is analyzed, error data is obtained, and the real-time radio frequency data is updated, comprising the following steps:
step S410, based on the real-time radio frequency data, the position data is called, the position of the search tank car is searched, and whether signal transmission around the tank car is good or not is confirmed;
step S420, if the obstacles around the tank truck are more, environmental error data are obtained according to the interference and attenuation suffered by the radio frequency signals;
step S430, acquiring weather data of the position of the tank truck according to the position data, and analyzing interference of weather on radio frequency signals to obtain weather error data;
step S440, the environmental error data and the weather error data are overlapped, the error analysis is carried out on the real-time radio frequency data, and the real-time radio frequency data are updated.
In practical application, the transmission of radio frequency signals is interfered by the surrounding environment, so that the data of the tank truck instrument can be accurately restored and analyzed to obtain the influence condition of the environment, and the accuracy of the data is facilitated. For example, the Beidou positioning obtains the position of the tank truck A, the surrounding mountains are relatively large, and the blocking signals attenuate radio frequency signals. The number of the tank truck is analyzed to be 1 according to the actually received tank truck radio frequency signal, but after the radio frequency signal is added with the attenuation signal, the number of the tank truck is analyzed to be 2. Tank car B is positioned in a plain zone with an open field of view, then the radio frequency signal sent by tank car B is received by the cloud server with little attenuation. Therefore, the data can be obtained by analyzing and judging according to the radio frequency signals actually received. The weather can also cause signal interference, and the error condition of the signal is analyzed according to the weather, so that the accuracy of the remote positioning monitoring data of the tank truck is improved.
Referring to fig. 2, based on the real-time radio frequency data, standard data is obtained, and after analysis, the position condition and the instrument parameters of the tank truck are restored to obtain real-time data, which comprises the following steps:
step S510, analyzing and then retrieving position data based on real-time radio frequency data, wherein the rest data are instrument data;
step S520, based on the instrument data, acquiring standard data of the tank truck when the tank truck does not operate, wherein the standard data comprise the tank truck standard data and the instrument standard data, and the instrument value corresponding to the instrument standard data is a standard instrument value;
step S530, based on the real-time radio frequency data and the tank car standard data, dividing the tank car radio frequency signal data to obtain instrument real-time data;
step S540, based on the instrument real-time data and the instrument standard data, analyzing the frequency band of the radio frequency signal and the size of the radio frequency signal, judging the specific value of the instrument, and combining the position data to obtain the real-time data.
In practical application, each meter of the tank truck has a unique radio frequency signal, and the radio frequency signal of the meter is not invariable, and the radio frequency signal of the meter can change along with the change of the value of the meter. The change of the numerical value of the instrument indicates the change of the tank truck. The change of the numerical value of the instrument is reversely pushed according to the change of the radio frequency signal of the instrument, so that the related data of the instrument are obtained. For example, the goods in the tank truck have consumption conditions, so that the pressure in the tank truck is reduced, the pressure sensor senses that the pressure is changed, the frequency range of the sent radio frequency signal is reduced, and after the frequency range of the radio frequency signal received by the cloud server is reduced, the actual pressure of the tank truck is analyzed to reduce, so that an accurate pressure value is obtained, and the accuracy of remote positioning and monitoring of the tank truck is improved.
Referring to fig. 3, based on the instrument data, standard data of the tank truck when not in operation is obtained, including tank truck standard data and instrument standard data, wherein an instrument value corresponding to the instrument standard data is a standard instrument value, and the method comprises the following steps:
step S521, distinguishing and marking the tank truck, obtaining related information of the tank truck and information of transported goods, and obtaining tank truck information data;
step S522, analyzing the frequency band of the radio frequency signal sent by the tank truck and the size of the radio frequency signal based on the tank truck information data to obtain tank truck signal data;
step S523, acquiring the frequency band of the radio frequency signal and the size of the radio frequency signal carried by the transported goods of the tank truck based on the tank truck information data to obtain the goods signal data;
step S524, combining the tank car signal data and the cargo signal data, and obtaining tank car standard data after superposition;
and step S525, recording the current value of each instrument, and obtaining instrument standard data by taking the current value as the standard instrument value.
In practical application, a plurality of tank trucks need to be positioned at the same time, and the tank trucks need to be distinguished to determine which tank truck corresponds to each piece of detected information. The tank car is inconsistent in the emitted radio frequency signals due to different materials and shapes, and the influence on the transported radio frequency signals is different due to different transported materials. For example, the cloud server receives the information of the three positions 1, 2 and 3 and simultaneously receives the radio frequency signals of the frequency bands A, B and C, so that according to the frequency band of the radio frequency signal of the tank truck, the position 1 is the radio frequency signal of the first frequency band, and the tank truck corresponding to the radio frequency signal of the first frequency band is the tank truck A. Similarly, the tank truck corresponding to the radio frequency signal in the B frequency band is the tank truck B, and the tank truck corresponding to the radio frequency signal in the C frequency band is the tank truck C. Therefore, the positions of a plurality of tank trucks can be determined within the same time period, and the occurrence of error confusion is reduced.
Referring to fig. 4, based on the standard data of the meter and the real-time data of the meter, the frequency band of the radio frequency signal and the size of the radio frequency signal are analyzed, the specific value of the meter is judged, and the real-time data is obtained by combining the position data, comprising the following steps:
step S541, obtaining the numerical value change of each instrument and the change coefficient of the radio frequency signal of the corresponding instrument, and obtaining instrument coefficient data;
step S542, based on instrument standard data and instrument real-time data, acquiring the frequency band change condition of all signals, synthesizing the frequency band change, dividing the data according to the frequency band of the radio frequency signals, and matching the instruments corresponding to the radio frequency signals;
step S543, obtaining the signal difference between the real-time radio frequency signal and the radio frequency signal under the standard value of the instrument according to the real-time data and the standard data of the instrument;
step S544, calculating to obtain the specific numerical value of each current instrument according to the signal difference and the instrument coefficient data, and obtaining real-time data.
In practice, each meter of the tank truck has its own unique frequency band, but the change in the value of the meter will cause a change in the radio frequency signal of the meter. In order to confirm the corresponding instrument of each radio frequency signal, the distinction can be made according to the comprehensive change of the frequency band. For example, the frequency band is A when the pressure is A, B when the temperature is B, and B is greater than A. However, the frequency bands of the received radio frequency signals are C and D, and both C and D are larger than A and B. According to the temperature rise, the pressure also rises, and meanwhile, D is larger than C, so that the pressure of the tank truck is C, and the temperature is D. The overall change of the instrument can be judged according to the overall change of the radio frequency signals, the instrument corresponding to each radio frequency signal is distinguished, and then a specific real-time instrument value is obtained according to the relation between the instrument value and the respective radio frequency change.
Referring to fig. 5, based on real-time data, data content is sent from a cloud server to a user terminal in a preset manner for viewing by a user, and the method comprises the following steps:
step S610, verifying the data based on the real-time data, confirming whether the tank truck is matched with the real-time data, and outputting data errors and giving an alarm if the tank truck is not matched with the real-time data;
step S620, if the data are matched, a preset sending mode set by a user is obtained, wherein the preset sending mode comprises the format, the theme and the variable name of the interactive data, and the cloud server sends real-time data according to the preset mode;
step S630, wherein the preset manner may be modified, and the publishing authority, the subscribing authority and the subscribing publishing authority of the data may be set, so as to obtain a data reporting period formulated by the user, and report the data according to the period.
In practical application, the most important of remote monitoring is to obtain data, and because the tank car has more and complicated data, a user can set a data issuing mode according to the requirement, and the first time of error data is notified, so that the occurrence of tank car safety accidents caused by time delay due to data errors of monitoring personnel is reduced. For example, the temperature data of the tank truck may be formatted in degrees celsius if the user considers that it does not conform to his data reading habits in degrees fahrenheit. In addition, if the user considers that the real-time data transmission is too frequent, the transmission period can be set to be one week, and then the data can be unified to be transmitted by arranging all the data in a unit of week. For some confidential information, data authority can be set, so that important data leakage is reduced.
Referring to fig. 6, based on the real-time data, the data is verified, whether the tank truck is matched with the real-time data is confirmed, if not, the data is output in error and an alarm is given, and the method comprises the following steps:
step S611, based on tank car information data, an RFID tag is written in through an RFID reader-writer and is arranged on a corresponding tank car;
step S612, deploying an RFID reader-writer in the transportation process, reading a unique identification code on an RFID tag, identifying tank truck information, acquiring the speed of the tank truck and the last positioning position, and judging whether the data are wrong;
step S613, if the data is correct, updating the position of the tank truck, if the data is correct, uploading alarm data by the cloud server, acquiring a data threshold set by a user, and uploading the alarm data if the data is correct;
step S614, the monitoring point set by the user is obtained, the cloud server uploads real-time data according to the monitoring point, and if the monitoring point is not set by the user, the cloud server uploads the data according to the period.
In practical application, confusion occurs when a plurality of tank trucks are monitored in the same time period. To avoid the occurrence of confusion to a greater extent, the vehicle is further validated. And reading the RFID tag arranged on the tank truck through a radio frequency identification technology, acquiring tank truck information, and verifying whether the data are correct. For example, matching tank truck A is position 1, and the vehicle speed is obtained, so that tank truck A is supposed to pass through the X point at 15:00 point. The RFID reader-writer at the X point reads the RFID tag of the tank truck when the RFID reader-writer at the X point is 15:00 points, the information content is tank truck A, and the data is correct. If the information content read by the RFID reader-writer at the X point at the 15:00 point is tank car B, the data error is described.
