Abstract
The utility model discloses a fuel management device, comprising a shell body, a circuit in the shell body and a power supply part. The utility model is characterized in that the main control unit of the circuit is a master SCM, and the input interface and the output interface of the SCM are respectively connected with a GSM module and a memorizer. The AD port of the SCM is connected with a signal conversion constant current source IC of an oil level sensor, another input interface is connected with an optocoupler module by isolating IC, and the optocoupler module is connected with a plurality of interfaces to receive switching-on and switching-off signals of an oil port sensor. When a fuel tank and an oil transport tank hatch generate abnormal situations, the fuel management device can memory and report the situations to a mobile phone of a management center, so the workload and the work difficulty of managers are reduced.
Description
Technical field
The utility model relates to a kind of fuel oil alarming management device that is applied to fuel tank of vehicle, transporting oil products jar mouth.
Background technology
At present, known fuel management systems can only be information stores such as fuel tank, transporting oil products jar mouth abnormal conditions in equipment, managerial personnel can only remove the change information of download equipment stored to every chassis, link to each other with computer then and carry out data analysis, bring the increase and the difficulty of workload like this to managerial personnel.
The utility model content
The utility model purpose is to provide a kind of fuel management device, and this device can be stored situation and report on administrative center's mobile phone at fuel tank, when abnormal conditions appear in transporting oil products jar mouth, has reduced managerial personnel's workload and work difficulty.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of fuel management device, comprise circuit board and power unit in housing, the housing, it is characterized in that, this circuit main logic unit is a main control singlechip, this single-chip microcomputer IO interface is connected with gsm module and storer respectively, the Chip Microcomputer A mouth links to each other with fuel level sensor conversion of signals constant current source IC, connect the optocoupler module through isolating IC on another road input interface, connect the multichannel interface on the optocoupler module and receive hydraulic fluid port sensor open and close signal.
The utility model can not only report to administrative center to fuel tank, transporting oil products jar mouth abnormal conditions with note by the gsm wireless network, and administrative center just can view short message content by mobile phone; And can store fuel tank, all situations of transporting oil products jar mouth, when need checking fuel tank, transporting oil products jar mouth situation of change, managerial personnel only need send dependent instruction, fuel management systems is used short message mode and is replied to managerial personnel, managerial personnel only need just can view all situations of every chassis fuel tank, transporting oil products car jar mouth in office like this, have alleviated managerial personnel's work load greatly.
Description of drawings
Fig. 1 is the utility model hardware configuration theory diagram.
Fig. 2 is the utility model software flow block diagram.
Embodiment
Be the utility model hardware configuration theory diagram as shown in Figure 1.This circuit main logic unit is a main control singlechip, and this single-chip microcomputer IO interface is connected with gsm module and storer respectively, and the Chip Microcomputer A mouth links to each other with fuel level sensor conversion of signals constant current source IC.Connect the optocoupler module through isolating IC on another road input interface, connecting multichannel interface reception hydraulic fluid port sensor on the optocoupler module opens, close signal, when unusual few oil or the unusual unlatching of fortune oil tank mouth appearance appear in fuel tank of vehicle, one road interface is sent to main control singlechip to oil level information with data through fuel level sensor conversion of signals constant current source IC, another road interface is opened data through the hydraulic fluid port sensor, close signal optocoupler module and be sent to main control singlechip, after main control singlechip is handled, notify at once on the mobile phone to administrative center, with the gsm wireless short message mode so that managerial personnel carry out real-time monitoring to fuel tank.
In the present embodiment, the main components and parts model of each several part is as follows:
1, main control MCU: C8051F340, system core control CPU.
2, switching signal input: TLP281, switching signal is isolated input.
3, sensor signal conversion: LM334, fuel level sensor conversion of signals constant current source.
4, warning message output: TC35, gsm module.
5, storer: WP25P40, the 4M-FLASH storer.
All switch input signals adopt TLP281 that input signal is carried out electrical isolation conversion back input single-chip microcomputer and handle, and can effectively protect single-chip microcomputer and improve system's antijamming capability.Thereby sensor input signal is to provide constant electric current to produce voltage change signal to the rheostat fuel level sensor by the LM334 constant current source, handles through the AD conversion input port of input single-chip microcomputer after the filtering.Signal output: LED light, alarm output signal, the output of All Alerts information are to send short message mode by gsm module to be sent on managerial personnel's mobile phone.During transmission information, the data communication LED light on the alarm can light expression and send information.
When the utility model uses, comprise the steps:
1, power-up initializing
Oil mass alarm power-up initializing is divided into gsm module initialization, initialize memory and fault input/output end port initialization three parts.For ensureing the trouble free service of all input and output ports, must check whether all of the port carefully connects the wire before powering on, forbid charged hot-swappable port wiring, otherwise damage port easily.After normal initialization is intact, the signal lamp of gsm module is operated in 75ms state that bright/3s goes out, power LED pilot lamp Chang Liang; The data communication LED light is bright when module receives note or sends note.When system uses for the first time, must be provided with, form is set in detail and order is set and see that the appendix A alarm is provided with explanation system.
2, the fault detect input and the output of reporting to the police
After the alarm operate as normal, if after having detected the failure alarm signal input, alarm sends to failure message on the managerial personnel's mobile phone that sets in advance by gsm module immediately.Warning message is divided into following several types:
(1), breaking-proof switch trigger to report to the police, two kinds that are divided into that the tamper of alarm fuselage is reported to the police and external tamper detector switch is reported to the police;
(2), the fuel level sensor abnormal alarm, be divided into fuel level sensor short circuit or breaking alarming two kinds;
(3) oil level abnormal alarm is divided into fuel tank oiling prompting and few unusually oily two kinds of fuel tank.
After each generation of reporting to the police, alarm can be noted the warning time of origin automatically, oil mass information during generation and warning message classification.After fault or oil level recovery normally, alarm can be noted the release time of reporting to the police automatically, and the oil mass information during recovery is in order to inquiry.
3, warning message storage
Alarm adopts 4M high-capacity FLASH store alarms information, can store 8192 recorded informations at most.Storage mode adopts the automatic coverage mode of circulation, and system will cover record the earliest automatically after storer uses up.
