2, the present invention by arranging door opening or closing monitoring, alarming unit in ammeter box, the open and-shut mode of ammeter chamber door can be measured timely and accurately, thus at ammeter box when by unauthorized unlatching, send warning message in time, for management of opposing electricity-stealing provides information timely and effectively.
3, present system framework is simple, easy to use, dependable performance, effectively can alleviate the labour intensity of electric system inspector simultaneously, improve work efficiency.
Accompanying drawing explanation
Fig. 1 is present system composition structural representation;
Fig. 2 is door opening or closing monitoring, alarming cellular installation position view of the present invention.
Embodiment
In the present embodiment, as shown in Figure 1, a kind of system composition of anti-unauthorized unlatching ammeter box comprises: ammeter box, door opening or closing monitoring, alarming unit, alarm monitoring center and work mobile phone;
Door opening or closing monitoring, alarming unit is provided with in ammeter box, as shown in Figure 2, usual door opening or closing monitoring, alarming unit can be fixed on the maximum displacement end facing door switch, and door opening or closing monitoring, alarming unit is made up of ultrasound wave transmit/receive module, MCU and gsm module A;
Ultrasound wave transmit/receive module is controlled to launch ultrasound wave to the chamber door of ammeter box by MCU, receive the ultrasound feedback that is reflected back of chamber door simultaneously and go out distance door opening or closing monitoring, alarming unit and chamber door between from launching ultrasound wave to the Time Calculation received the ultrasound wave that is reflected back according to ultrasound wave transmit/receive module to MCU, MCU; When the chamber door closed condition distance value that Distance geometry between door opening or closing monitoring, alarming unit and chamber door sets is inconsistent, then assert that chamber door is by unauthorized unlatching, MCU produces warning message and is sent to alarm monitoring center by gsm module A;
MCU with the annexation of ultrasound wave transmit/receive module is: the TIM1 interface of MCU is connected with OUT pin with the IN pin of ultrasound wave transmit/receive module respectively with TIM2 interface, for controlling ultrasound wave transmit/receive module transmitting and receiving ultrasound wave.MCU is to the initialize signal of the IN pin transmission ultrasonic frequency of ultrasound wave transmission/reception module, then ultrasound wave is launched through the backward chamber door of ultrasound wave transmit/receive module process, carried to MCU by OUT pin through inter-process after ultrasound wave transmit/receive module receives the ultrasound wave that chamber door reflects, MCU to be counted the signal fed back by inner TIM2 and the process of data;
Alarm monitoring center is the core of whole system, by alarm monitoring central server, gsm module B and alarm monitoring software sharing; Mobile network all by common carrier between the gsm module A of door opening or closing monitoring, alarming unit and the gsm module B at alarm monitoring center carries out both-way communication, door opening or closing monitoring, alarming unit is once monitor chamber door by unauthorized unlatching, by gsm module A, warning message is sent to warning system Surveillance center immediately, gsm module B receives warning message and uploads to the enterprising row relax of alarm monitoring central server by RS232 serial ports.The warning message read is sent to work mobile phone by gsm module B in SMS mode by RS232 serial ports by the alarm monitoring software of alarm center server.
Work mobile phone receives the warning message that alarm center server is sent by gsm module B, and the information of corresponding unauthorized unlatching ammeter box is obtained according to warning message, oppose electricity-stealing for power supply department and information is timely and effectively provided, unauthorized unlatching ammeter box is detected and is processed simultaneously the behavior of unauthorized operation table case timely, the generation of electricity theft prevention behavior.
When door opening or closing monitoring, alarming cellular installation is in ammeter box, need under the chamber door state of closing ammeter box, complete study distance process by the alarm monitoring software at alarm monitoring center, concrete steps are as follows:
Step one, by door opening or closing monitoring, alarming cellular installation in ammeter box, to power on and initialization gsm module A and ultrasound wave transmit/receive module;
The chamber door of step 2, closedown ammeter box, alarm monitoring central server sends study distance in GPRS/SMS mode to door opening or closing monitoring, alarming unit by gsm module B and orders, MCU in door opening or closing monitoring, alarming unit reads the order of study distance via gsm module A, ultrasound wave is launched to the chamber door of closed condition by ultrasound wave transmit/receive module, the ultrasound wave that the chamber door simultaneously receiving closed condition is reflected back, MCU is multiplied by hyperacoustic speed from transmitting ultrasound wave to hyperacoustic time that reception is reflected back according to ultrasound wave transmit/receive module and obtains the total distance of ultrasonic propagation, the half of the total distance of ultrasonic propagation is the closed condition distance value of actual door opening or closing monitoring, alarming unit to chamber door, closed condition distance value is stored in the FLASH in MCU by MCU, study distance process terminates.
Because the relative position of chamber door and ultrasound wave transmitter/receiver unit is fixed, detecting distance is between the two certain, once detecting distance change exceedes certain value, then judges that the open and-shut mode of chamber door changes, produces the warning message that chamber door is opened.But the non-open-type slight perturbations phenomenon occurred due to extraneous factor due to the chamber door of ammeter box and the change causing monitoring distance to occur, and then go out present condition and to make a mistake judgement, therefore chamber door is opened monitoring, alarming unit and can be set threshold value to the distance change preset, when the distance changed is greater than setting threshold value, just judge that door opening or closing state changes, otherwise it is constant to be considered as state.That is on the basis of the chamber door closed condition distance value of original setting, reset the threshold value of a distance change, what exceed this threshold range is just judged as that chamber door is by unauthorized unlatching.
When the mobile phone that works needs initiatively to open ammeter box, the unpacking request of application can be sent to the gsm module B at alarm monitoring center, alarm center server is unpacked by the application that RS232 serial ports reading gsm module B receives and is asked and judge whether the unpacking request of application is legal, when applying for that the request of unpacking is legal, send to report door opening or closing monitoring, alarming unit instruction of withdrawing a garrison by gsm module B, the TX pin of MCU is connected with TX pin with the RX pin of gsm module A respectively with RX pin, operation of withdrawing a garrison is completed after reading order of withdrawing a garrison, and information feed back will have been withdrawn a garrison to alarm monitoring center by gsm module A, alarm monitoring receive centre has been withdrawn a garrison after information and has been sent authorized order to work mobile phone, work mobile phone receives authorized order can carry out authorizing operation of unpacking, operated rear pass case then door opening or closing monitoring, alarming unit again automatically deploy troops on garrison duty, if close ammeter box to need behind the door again to unpack, then need again to apply for operation of unpacking, otherwise the identification of door opening or closing monitoring, alarming unit is unpacked as unauthorized operation, produce warning message and be sent to alarm monitoring center.
