Abstract
The utility model relates to a device for detecting and recording shell opening time in real time, which comprises a control unit, a real-time clock unit, a power supply unit and a detecting unit. The control unit is respectively connected with the real-time clock unit, the power supply unit and the detecting unit. The detecting unit is used for detecting switching signals of a shell, and the detecting unit sends a closing detection signal to the control unit when the shell is closed and sends an opening detection signal to the control unit when the shell is opened. The device for detecting and recording the shell opening time in real time has the advantages that the device can record the opening time and opening times of devices with the shell, such as electronic scales and the like and contrasts with recorded and legal calibration information, and then illegally calibrated time and times can be found.
Description
Technical field
The utility model belongs to the automatic control technology field, relates in particular to a kind of detection technique of can the real time record shell opening information.
Background technology
The means of practising fraud on the present electronic scales market emerge in an endless stream, and except illegal demarcation, also have such as the chip on the mainboard in interpolation telepilot of the sensor side in electronic scales or the replacing electronic scale to repack the cheat methods such as scale of giving short weight into.It is exactly to need the shell of unlocking electronic scale to operate that but these cheat methods all have a common characteristic.Electronic scales is in the market preventing that opening the shell this respect has only done the lead sealing of mechanical system to prevent from illegally to open shell.But still have a lot of illegal retailers to make a desperate move, the shell of illegal unlocking electronic scale and to its repacking cheating to seek exorbitant profit.After supervision department discovers and seizes it, when do not practise fraud because of knowing illegal retailer, used the time how long, so be difficult to punish the judgement of amount.
The utility model content
The purpose of this utility model is in order to monitor and to prevent that the device that electronic scales etc. has a shell from illegally being opened, having proposed a kind of real-time detection and record shell open-interval device.
To achieve these goals, the technical solution of the utility model is: a kind of real-time detection and record shell open-interval device, comprise control module, real-time clock unit and power supply unit, it is characterized in that, also comprise detecting unit, described control module is connected with real-time clock unit, power supply unit and detecting unit respectively, described detecting unit is in order to detect the switching signal of shell, detecting unit will be closed detection signal and be sent into control module when enclosure closed, when shell was opened, detecting unit was sent the open detection signal into control module.
The beneficial effects of the utility model: opening time and number of times that the utility model can have electronic scales etc. the device of shell carry out record, by comparing in the legal calibration information that has write down, just can find illegal time and the number of times of demarcating.Further, first control module can also be sent a switch controlling signal into second control module, and second control module can enter guard mode after receiving switching signal, has only through ability de-preservation state after the legal demarcation again.Thereby realize electronic scales etc. is had the effective monitoring management of the device of shell, prevent various cheatings.

Fig. 2 is the circuit theory synoptic diagram of the utility model embodiment 2.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment 1: as shown in figures 1 and 3, a kind of real-time detection and record shell open-interval device, comprise control module, real-time clock unit, power supply unit and detecting unit, described control module is connected with real-time clock unit, power supply unit and detecting unit respectively, described detecting unit is in order to detect the switching signal of shell, detecting unit will be closed detection signal and be sent into control module when enclosure closed, and when shell was opened, detecting unit was sent the open detection signal into control module.
Above-mentioned control module adopts single-chip microcomputer, and the control module while of present embodiment is as the control module of electronic scales.Above-mentioned real-time clock unit can be integrated into control module on physical arrangement, also can separate with control module.Above-mentioned power supply unit adopts button cell or general dry battery usually.
Embodiment 2: as shown in Figures 2 and 3, the difference of present embodiment and embodiment 1 is, control module is divided into first control module and second control module, described first control module is connected with real-time clock unit, power supply unit and detecting unit, second control module is connected by universal serial bus with first control module, and time that first control module record shell is opened and number of times also send a switch controlling signal to second control module.In the present embodiment, first control module a control module as this device, second control module a control module as electronic scales, so this device can separate by different manufacturer production, sale and assembling with electronic scales.Remaining part is identical with embodiment 1, therefore is not described in detail.
Those of ordinary skill in the art will appreciate that embodiment described here is in order to help reader understanding's principle of the present utility model, should to be understood that protection domain of the present utility model is not limited to such special statement and embodiment.Everyly make various possible being equal to according to foregoing description and replace or change, all be considered to belong to the protection domain of claim of the present utility model.
