Problems solved by technology

[0004] The technical problem to be solved by the present invention is that it takes a lot of manpower and material resources to monitor criminal suspects by fixed-point personnel. Under certain circumstances, adequately monitor the power consumption of the suspect's home or other suspicious residences or places, so as to determine whether and when the suspect is present in the target building

Embodiment 1

[0039] Such as figure 1 As shown, the present invention provides a power consumption information collection system for criminal investigation monitoring, including a power supply module 1 , a sensor module 2 , a signal collection module 3 , a data processing module 4 , a signal transmission module 5 and a monitoring terminal 6 . The power supply module 1 is used to provide working power for the sensor module 2, the signal acquisition module 3, the data processing module 4 and the signal transmission module 5; the sensor module 2 is set in the main circuit of the suspect's home or other suspicious residences or places above, used to collect the electricity current information of the main circuit under test and obtain the analog signal, and send the analog signal of the electricity information to the input end of the signal acquisition module 3; the signal acquisition module 3 is used to collect the information collected by the input end An analog signal, converting the analog s...

Embodiment 2

[0042] Further improvement on the basis of Example 1, the power module 1 uses a lithium battery, model: HX-M-N01, 12V3A 2000mAh.

[0043] The sensor module 2 adopts an AC transmitter, model: KXK-36 / 50A~500A, which is used to directly collect the power consumption information of the main circuit under test to obtain an analog signal; the measurement range of the AC transmitter is 0~50A, and at 10A Scale (±5A range) error is less than 1%.

[0044] The signal acquisition module 3 uses a voltage comparator, model: LM393PGBQ, which is used to collect the analog signal collected at the input terminal, and quantify it into a corresponding logic level, and judge the real and effective current threshold signal through the internal timing and delay logic.

[0045] The data processing module 4 is connected to the signal transmitting module 5 through a serial port 7 .

[0046] Data processing module 4 adopts MCU processor, model: STC12C5A60S2.

[0047] The signal transmitting module 5 a...

Abstract

The invention discloses a power consumption information acquiring system for criminal investigation monitoring. The system comprises a power supply module, a sensor module, a signal acquiring module, a data processing module, a signal transmitting module and a monitoring terminal. The sensor module is arranged at a suspected residence of a suspect or a main loop of the residence and acquires power consumption current information of the tested main loop for acquiring an analog signal and transmitting the analog signal to the signal acquisition module. The signal acquiring module converts the analog signal to a digital signal and transmits the digital signal to the data processing module. The data processing module performs analysis according to a preset current threshold. When the suspect appears in home or other suspected residences or places and a power consumption behavior occurs, the data processing module analyzes a fact that the present current is higher than the preset current threshold, and the data processing module transmits reminding information to the monitoring terminal through the signal transmitting module. The power consumption information acquiring system can effectively help investigation personnel in sufficiently monitoring the power consumption condition in the home or other suspected residences or places of the suspect, thereby determining whether the suspect appears in a target building and when the suspect appears in the target building.

Description

technical field [0001] The invention relates to a power monitoring system, in particular to a power consumption information collection system for criminal investigation monitoring. Background technique [0002] With the gradual development of safe power construction in various places, the joint construction of government, enterprise, police and enterprises has been further promoted, resources are shared, information is exchanged, and mutual benefit, win-win and common development have been realized. [0003] The fixed-point monitoring of criminal suspects by law enforcement agencies such as public security organs is an important means of case detection, but the fixed-point monitoring of criminal suspects requires a lot of manpower and material resources, so in actual implementation, it is often due to insufficient manpower Or there are too many tasks, resulting in insufficient monitoring or real-time monitoring, which affects the progress of case detection to a certain exten...
