Description
Technical field
The utility model relates to electronic applications, particularly, relates to a kind of load carrying vehicle fuel oil monitored control system based on temperature and pressure transmitter.
Background technology
The load carrying vehicle of logistics enterprise can configure a large-scale fuel tank usually, for depositing a large amount of fuel oils, meets long-distance transport needs.Because fuel price is in a high position always, and still rise steadily, fuel oil occupies significantly proportion always in logistics enterprise cost.The high price of fuel oil also impels some lawless persons when vehicle no supervision, takes advantage of the occasion to steal the fuel oil in load carrying vehicle fuel tank, brings massive losses to enterprise.Meanwhile, because vehicle travels outside throughout the year, inclement weather or other accidents also can cause fuel tank leakage of oil.Because existing load carrying vehicle does not mostly have fuel oil monitored control system, when above-mentioned fuel oil ANOMALOUS VARIATIONS occurs, car owner or logistics enterprise also just can not Timeliness coverage stop the loss of property.
Utility model content
The purpose of this utility model is, for the problems referred to above, proposes a kind of load carrying vehicle fuel oil monitored control system based on temperature and pressure transmitter, to realize immediately obtaining load carrying vehicle fuel oil abnormal information, avoids the advantage of losing.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of load carrying vehicle fuel oil monitored control system based on temperature and pressure transmitter, comprise car-mounted terminal, temperature and pressure transmitter, receptor and feedway, the oil tank fuel liquid level data that described temperature and pressure transmitter detects sends through feedway, pass to car-mounted terminal after the liquid level data that feedway sends is received by the receiver, memory device and comparator are set in described car-mounted terminal.
Further, described feedway comprises projector, antenna and repeater, projector launch wireless signal through antenna amplify after, pass to repeater, this repeater by receive signal transmission to receptor.
Further, also comprise mobile monitoring terminal, this mobile monitoring terminal is connected with car-mounted terminal by radio communication.
The technical solution of the utility model has following beneficial effect:
The technical solution of the utility model, by providing a kind of monitored control system, by real-time the detecting oil tank fuel temperature and liquid level change of sensor, and liquid level delta data is passed to car-mounted terminal in real time, the fuel liquid level that car-mounted terminal sets when the fuel liquid level delta data recorded and its normally being travelled is changed and is compared by comparator, if record fuel liquid level rate of change to be greater than setting value, give the alarm, car owner or logistics company is reminded to note, thus the fuel leakage that timely prevention fuel oil is stolen or other reasons causes, avoid property damage.Solve the existing load carrying vehicle shortcoming that car owner or logistics enterprise can not be known in time when fuel oil ANOMALOUS VARIATIONS, reach instant acquisition load carrying vehicle fuel oil abnormal information, avoid the advantage of losing.
Accompanying drawing explanation
Fig. 1 is the functional block diagram of the load carrying vehicle fuel oil monitored control system based on temperature and pressure transmitter described in the utility model embodiment;
Fig. 2 is the electrical circuit diagram of the comparator described in the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of load carrying vehicle fuel oil monitored control system based on temperature and pressure transmitter, comprise car-mounted terminal, temperature and pressure transmitter, receptor and feedway, the oil tank fuel liquid level data that temperature and pressure transmitter detects sends through feedway, pass to car-mounted terminal after the liquid level data that feedway sends is received by the receiver, memory device and comparator are set in car-mounted terminal.
Temperature and pressure transmitter adopts Integrated Sensor Chip of Temperature and Pressure, and data for detecting oil tank fuel liquid level data, and are passed to feedway by Integrated Sensor Chip of Temperature and Pressure; This data wireless for receiving the detection data of Integrated Sensor Chip of Temperature and Pressure, and is launched by feedway; Receptor is connected with car-mounted terminal, for the data that receiving and transmitting unit transmits, and these data is passed to car-mounted terminal; A configuration memory device and a comparator in car-mounted terminal, fuel oil consumption speed during memory device internal memory warehousing fortune normal vehicle operation, comparator is used for the data received and fuel oil consumption speed to compare.If the fuel liquid level rate of change recorded is greater than normal fuel oil consumption speed, give the alarm, remind car owner or company to note, the situation generation that the fuel leakage etc. that the stolen or other reasons of fuel oil so just can be stoped in time to cause causes any property loss.Comparator in this technical scheme is adopt hardware circuit to realize.
Wherein, this data wireless for receiving the detection data of Integrated Sensor Chip of Temperature and Pressure, and is launched by feedway; Consider that existing projector transmitting range is shorter, and the stop of some steel plates on vehicle body, an independent projector is difficult to signal transmission to receptor.So feedway comprises projector, antenna and repeater in the technical program, projector is used for wireless signal emission, and antenna effect is that the wireless signal for being launched by projector amplifies, and enables to transmit farther distance, data for receiving data, and are passed to receptor by repeater.Feedway comprises projector, antenna and repeater, projector launch wireless signal through antenna amplify after, pass to repeater, this repeater by receive signal transmission to receptor.
In the technical solution of the utility model, if when load carrying vehicle normally travels, then the fuel liquid level signal indication of load carrying vehicle is the oleaginousness of fuel tank, and the variable quantity of liquid level signal is the normal consumption speed of fuel oil.
In the technical solution of the utility model, Integrated Sensor Chip of Temperature and Pressure, for testing liquid level change and the change of fuel oil temperature of fuel oil, is considered temperature factor, liquid level is tested more accurate.
In the technical solution of the utility model, can mobile monitoring terminal be set, as mobile phone or other there is the handhold portable equipment of wireless telecommunications, facilitate supervisor to carry out remote monitor and control; Mobile monitoring terminal also can be logistics company transport vehicle monitoring and control centre, conveniently monitors a large amount of load carrying vehicles simultaneously.
Have a memory device and a comparator in car-mounted terminal, fuel liquid level rate of change when storing normal vehicle operation in memory device, when comparator is used for the data received and described fuel liquid level normally to travel, rate of change compares.If the rate of change of fuel oil, just gives the alarm when fuel liquid level rate of change is greater than normal vehicle operation, car owner or logistics company monitor staff is reminded to note.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
