Description

The power utility check monitoring system
Technical field
The utility model relates to the power utility check monitoring system.
Background technology
Although power supply enterprise is sternly hit the stealing activity always, also dropped into substantial contribution measuring apparatus has been carried out power-steeling preventing electric reform, but under the ordering about of interests, the still continuous conversion of electricity filching person various movements in martial arts and is carried out stealing, and therefore the work of opposing electricity-stealing still is the challenge that our power supply enterprise faces.
Because measuring apparatus generally is installed in the user place, bring great convenience for like this user's stealing.They can carry out concealed and technical stealing at the house lead in situation of house lead in and the defective of measuring apparatus itself, and we adopt the routine inspection mode be difficult to find its electricity filching behavior like this, cause to look into stealing work and can not get a desired effect.The at present domestic equipment that does not also have moulding at inspection hidden-type and poly-talented stealing.
The utility model content
The technical problems to be solved in the utility model provides a kind of power utility check monitoring system, and this system can provide safety, accurate, reliable information for investigating and prosecuting stealing work, is used for sternly hitting the various stealing activities that the stealing one's share of expenses for a joint undertaking is taked.
In order to solve the problem that prior art exists, the technical solution adopted in the utility model is:
The power utility check monitoring system, electricity consumption monitoring instrument that comprises the sampling instrument, constitutes by multi-functional computation chip of electronic type and GPRS wireless transport module and the terminal that is connected the internet, the output terminal of sampling instrument links to each other with the input end of the multi-functional computation chip of electronic type, and the output terminal of the multi-functional computation chip of electronic type links to each other with the GPRS wireless transport module; Terminal links to each other with the mobile base station with network trunk by cable broadband.
Described sampling instrument divides current transformer to form by collector potential-divider network and collector.
The multi-functional computation chip of described electronic type is made up of 16 A/D converters 21, DSP high-speed data processor 22, cpu central processing unit 24 and storer 23, the output terminal of 16 A/D converters 21 links to each other with DSP high-speed data processor 22, the output terminal of DSP high-speed data processor 22 links to each other with an end of cpu central processing unit 24, and the other end of cpu central processing unit 24 links to each other with storer 23.
Advantage and effect that the utility model had are:
1, the utility model can be installed under the charged like this situation owing to adopt the opening mutual inductor, and is safe, hidden, quick, guaranteed the data accuracy of gathering; Need not have a power failure during installing/dismounting, relatively secret is installed, can accurately grasp the actual power consumption of user;
2, the utility model can very fast eliminating stealing family and non-stealing family, can check according to field condition for the stealing user; To non-stealing user, can remove equipment, be installed on the other suspicion family, without great amount of investment;
3, the utility model can long-rangely carry out watch-keeping to the user power utilization situation, but wireless transmission reads electric weight.Do not use the erecting stage and check meter, all data can be kept in the computer, are convenient to analysis management;
4, the utility model can be monitored how tame suspicion user simultaneously;
5, the utility model system host is need not 24 hours online, only needs that parameter setting, data are recalled, online getting final product when monitor is detected control;
When 6, the utility model main frame is not online, to the data of having stored can calculate as usual, analyze, preserve, the maintenance of printing and database;
7, the utility model infield is flexible, is not afraid of and exposes to the weather.And all install without each user, suspectable user only is installed, have dirigibility;
8, the design of native system is developed in conjunction with the hidden-type that generally adopts on the current social and the characteristics of poly-talented stealing.Investigate out earlier stealing suspicion user before the installation, carry out hidden installation, monitoring according to the characteristics of this user's house lead in then.Both can accurately get rid of non-stealing family by the result who monitors, also can assert the stealing user accurately, therefore can effectively hit the arrogance that adopts hidden-type and poly-talented stealing user.
9, the utility model need not specially be made of the table case because the set-up time is of short duration, reduces investment outlay.
10, the utility model can be found user's electricity filching behavior timely and effectively, and accuracy rate is high, and has versatility, and is reusable, reduces investment outlay.
Indicators of overall performance of the present utility model is: temperature :-35 ℃~+ 50 ℃; Relative humidity≤85%; Harmonic content≤10%; The test number of phases: three-phase; Voltage V:380,220; Electric current A:0~5; Frequency HZ:50 ± 2; Voltage: ± 0.5; Electric current: ± 0.5; Meritorious electric weight: ± 1.0%; Capacity of idle power: ± 2.0%; Power factor: ± 1.0%; Withstand voltage experiment: voltage: 6KV/50us; Power-frequency voltage 2KV/1min; Electromagnetic interference (EMI) experiment: horizontal/vertical: 0.5mT; Alternating electromagnetic field: 30 °.
