In addition, after executing envelope and finishing, can add sealing cap 69 in the part that leaks outside of control piece 111, with protection control piece 111, simultaneously also more attractive in appearance.

See also Figure 12, Figure 12 is the principle block diagram of the electronics envelope of the utility model second embodiment; Embodiment illustrated in fig. 12 and embodiment illustrated in fig. 1 comparing, it ties identical substantially, different is to have set up metal detection circuit 150, when metal object seals near electronics, the metal detection circuit will send the signal of telecommunication to second control circuit 140, second control circuit 140 produces second control signal and gives voice alarm circuit 1322, sends audio alert.In embodiment illustrated in fig. 12 with embodiment illustrated in fig. 1 in the same circuits part, the front was narrated, and repeated no more here.Power supply in this example can be provided by the power circuit among Fig. 8.

Figure 13 is a partial circuit principle schematic embodiment illustrated in fig. 12.As shown in the figure, circuit includes only metal detection circuit, second control circuit and three parts of voice alarm circuit among the figure.The metal detection circuit comprises adjustable resistance W4, resistance R 29, R30, R31, R32, R33, inductance L 1, L2, L3, capacitor C 16, C17, C18.Wherein, inductance L 1, L2, L3, capacitor C 16 and triode T23 constitute high-frequency generator.Second control circuit comprises diode D41, D42, triode T23, T24; Voice alarm circuit comprises integrated circuit (IC) 8, loud speaker, resistance R 33, adjustable resistance W5 and triode T25.The voice alarm circuit that this voice alarm circuit also can be used as among Fig. 1 is used, and it only need join with the junction associated among Fig. 8 and get final product, and its connection is that the those of ordinary skill of the industry is all attainable, here no longer carefully narration.

When not having metal object near high-frequency generator, high-frequency generator work, oscillator signal obtains direct voltage and makes triode T24 conducting through D41, D42 voltage multiplying rectifier, and triode T25 ends; As metal objects, as screwdriver when the high-frequency generator, the high-frequency generator failure of oscillations, triode T24 ends, the T25 conducting triggers integrated circuit (IC) 14 to loud speaker output voice signal, thereby enters tone playing state.Wherein, integrated circuit (IC) 8 can be ISD1420.

Need explanatorily be, except that aforementioned this combination, can according to actual needs above-mentioned functions be carried out new combination for the electronics envelope that has moving envelope warning function, sound prompt function and metal inducing function simultaneously.For example, after producing alarm signal, this alarm signal can be transferred to voice alarm circuit, by voice alarm circuit warning message is exported by the mode of voice, with the user that points out scene and/or remote control terminal place or the administrative staff prevention malfeasance that takes appropriate measures, thereby avoid loss.And for example, when metal detection circuit 150 has been sensed metal object near this electronics envelope, promptly produce corresponding voice output control signal, and transmit it to voice alarm circuit 1322 to export default information by speech form, remind user or administrative staff, perhaps warn lawless people; Also can produce corresponding alarm signal.

The front is enclosed in the application of gauge table case with electronics of the present utility model, and the utility model is described.In fact, the electronics envelope that the utility model provides also can be applied to other occasions outside the administration of power networks, as long as for example management of the management of water meter, fuel gauge, gas meter, flow meter or the like is the peripheral circuit that adds according to actual needs or change corresponding function and select to be fit to.In this case, executive circuit can be electrically-controlled valve, for example electromagnetically operated valve.When the moving envelope of people, testing circuit is exported moving envelope signal and is given control circuit, and control circuit is according to being somebody's turn to do the action of moving envelope signal controlling electrically-controlled valve, and valve-off is with blocking-up water route, oil circuit, gas circuit, thus the prevention malfeasance, and then avoid loss.

Certainly, the electronics envelope that provides of the utility model also can be applied to such as in non-pipelines such as container management, oil truck management, the logicalnot circuit management.In this case, executive circuit can only comprise warning circuit and needn't have such as executive components such as relays.Like this, loosening and/or when destroying electronics envelope on the container as the people, this electronics envelope can be reminded administrative staff to take effective measures by type of alarm and be prevented malfeasance, to avoid loss.

Be understandable that above execution mode only is the illustrative embodiments that adopts for principle of the present utility model is described, yet the utility model is not limited thereto.For those skilled in the art, under the situation that does not break away from spirit of the present utility model and essence, can make various modification and improvement, these modification and improvement also are considered as protection range of the present utility model.
