Description

Technical Field

[0001] The utility model relates to the technical field of power distribution equipment, in particular to a concentrator box device used by the power sector. Background Art

[0002] The concentrator used by the power sector is the central management and control equipment of the remote centralized meter reading system. It has the functions of reading terminal data regularly, transmitting system commands, data communication, network management, event recording, and horizontal data transmission. The concentrator box is a supporting mechanism for the concentrator. Its main function is to install the concentrator and other auxiliary equipment, prevent external rainwater from entering the box and causing abnormal operation or damage to the concentrator, and prevent the user from opening the box door and short-circuiting the incoming and outgoing terminals to steal electricity (the box can also prevent violent damage).

[0003] Although the existing concentrator boxes have met the actual needs to a certain extent, due to structural limitations, there are still some technical problems that need to be solved urgently. First: the box door is closed and locked with a lock. When the personnel in the power-consuming area use a key (such as a privately made key) or other non-permitted methods to open the box door, it is impossible to effectively prevent the relevant personnel from stealing electricity. Second: it does not have a power outage reminder function. When the concentrator itself and other electrical auxiliary components fail and cause a power outage, the relevant personnel who are not on site cannot promptly understand the relevant situation and deal with it accordingly, which will more or less have an adverse effect on the power consumption in the relevant area. In summary, it is very necessary to provide a concentrator box device that can effectively prevent electricity theft and can promptly remind remote relevant personnel to deal with it when the power supply is stopped.

BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] Figure 1 ,2 As shown in the figure, a concentrator box device used by the power department includes a concentrator box body 3 with a hinged installation and a box door 2 locked by a lock 1, a solar panel G1, a battery G2, a text message module E2, and a relay K1; it also has a box door detection circuit 4 and a timing circuit 5; the solar panel G1 is installed on the upper end of the box body 31 of the concentrator box body, the box door detection circuit is equipped with a magnet CT and a reed switch GH, and the right rear end of the box door 2 of the concentrator box body has a front concave fixing groove, and the fixing groove is glued with A rectangular permanent magnet CT is connected, and the rear end of the magnet CT and the rear side of the box door 2 are in the same vertical plane. A rear concave mounting groove is provided on the left side of the right front end of the box body 31. The reed switch GH is vertically glued in the mounting groove, and the front end of the reed switch GH and the front end of the mounting groove are in the same vertical plane. The moving contact of the reed switch GH is located at the front end. The battery G1, the SMS module E2, the box door detection circuit 4, the timing circuit 5, and the relay K1 are installed on the circuit board in the component box 6, and the component box 6 is installed at the upper end of the box body 3.

[0015] Figure 1 , 2 As shown in , the reed switch GH is a normally closed contact reed switch. After the door 2 is closed, the rear end of the magnet CT is vertically located at the front end of the reed switch GH and is spaced a certain distance (2 mm). The moving contact and the static contact inside the reed switch GH are in an open circuit state. The door detection circuit includes a resistor R1 and a transistor Q1 connected via circuit board wiring, and one end of the resistor R1 is connected to the base of the transistor Q1. The timing circuit includes a pyroelectric detection module E1, resistors R2 and R3, a capacitor C1, and a transistor Q2 connected via circuit board wiring. The signal output end 3 pin of the pyroelectric detection module E2 is connected to one end of the first resistor R2, the other end of the first resistor R2 is connected to one end of the second resistor R3 and the positive electrode of the capacitor C1, the other end of the second resistor R3 is connected to the base of the transistor Q1, and the negative electrode of the capacitor C1 is connected to the emitter of the transistor Q2. The two poles of the solar panel G1 and the battery G2 are connected together through wires, and are connected to the power input end of the SMS module E2, one end of the reed switch GH of the power input end of the door detection circuit, the emitter of the transistor Q1, the power input end of the timing circuit, and the power input end 1 and 2 of the pyroelectric detection module E1 through wires, respectively. The signal output end of the door detection circuit, the collector of the transistor Q1, the signal output end of the timing circuit, the collector of the transistor Q2, the normally closed contact end of the relay K1, and the signal input end 3 of the SMS module E2 are connected through wires. The power input end of the relay K1 and the AC 220V two-pole incoming line end of the concentrator box body are connected through wires. The control power input end of the relay K1 and the negative pole of the battery G2 are connected through wires, and the other end of the reed switch GH is connected to the other end of the resistor R1. There is an opening on the upper part of the front side of the door, and the front side end of the detection head of the pyroelectric detection module E2 is located outside the front end of the door.

[0016] Figure 1 , 2 As shown, the new type is based on the concentrator box body 3 (installed outdoors) and has the function of installing the concentrator 7 and other accessories. Usually, the solar panel G1 generates electricity under the sunlight to charge the battery G2, ensuring that the corresponding circuit can still be powered and work normally during a power outage. The 12V power output by the battery G2 enters the power input end of the SMS module E2, the box door detection circuit, and the timing circuit, and the above modules and circuits are powered and work. After the box door detection circuit is powered and works, if the box door 2 is effectively closed, the magnetic force of the magnet CT at the rear end of the right side of the box door acts on the reed switch GH, and the internal contacts of the reed switch GH are open. The 12V power will not enter the base of the transistor Q1, and the SMS module E2 will not send SMS accordingly. When someone opens the door to steal electricity by short-circuiting the input and output terminals of the concentrator 7, etc., or opens the door 4 without permission (such as a privately-made key, etc.), the magnet CT at the rear end of the right side of the door and the front end of the reed switch GU are spaced apart, and the magnetic force of the magnet CT no longer acts on the reed switch GH. The internal contact of the reed switch GH is closed, and the 12V power supply enters the base of the transistor Q1 through the resistor R1 to reduce the voltage and limit the current. The transistor Q1 conducts the collector and outputs a low level into the base of the transistor Q1. The transistor Q1 conducts the collector and outputs a low level into the 3rd pin of the SMS module E2. The SMS module E2 will send out the SMS stored inside. After the timing circuit is powered on, when no one approaches the front end of the box 31, the 3rd pin of the pyroelectric detection module E1 does not output a high level, and the corresponding SMS module will not send SMS. When someone approaches the front end of the box 31, the 3rd pin of the pyroelectric detection module E1 outputs a high level, and the high level is reduced by the resistor R2 to limit the current to charge the capacitor C1. In the initial period of time (for example, less than 1 minute), the 12V power supply enters the base of the transistor Q2 through the resistors R2 and R3 to reduce the voltage and limit the current to less than 0.7V, the transistor Q2 will not be turned on, and the SMS module E2 will not send SMS messages. After charging for a period of time (for example, more than 1 minute, if the time is too long, it is possible that someone uses other tools to open the box door in front of the box door because there is no matching key), the 12V power supply enters the base of the transistor Q2 through the resistors R2 and R3 to reduce the voltage and limit the current to more than 0.7V, the transistor Q2 will be turned on and the collector outputs a low level to the 3rd pin of the SMS module E2, and the SMS module E2 will send out the SMS stored inside (the one-minute delay is to prevent the SMS module from sending SMS messages when someone passes by under normal circumstances; under normal circumstances, people will not stand in front of the equipment for more than one minute continuously, so the one-minute delay can fully meet the control needs). When there is no power outage on site, relay K1 is energized to attract its control power supply and open the normally closed contact end, and the SMS module E2 will not send SMS. When there is a power outage on site, relay K1 loses power and no longer attracts its control power supply and normally closed contact end to close. The negative pole of the 12V power supply enters pin 3 of the SMS module E2 through the control power input end and normally closed contact end of relay K1, and the SMS module E2 will send out the SMS stored internally.

[0017] Figure 1 , 2 As shown above, the new type can push a reminder SMS to the remote relevant personnel through the SMS module in the first time when someone opens the box door without permission or stays in front of the box for too long (too long time means that there may be no matching key and someone uses other tools to open the box door), there is a possibility of electricity theft, and when there is a power outage on site, the relevant personnel can go to the site in time to deal with it after receiving the SMS, thereby playing the role of preventing electricity theft and reliable power supply. It should be noted that under normal circumstances, the relevant personnel open the box door and observe the corresponding readings at the front side. Although the SMS module will also send SMS, the relevant personnel understand the situation themselves and can completely ignore the SMS, so it will not affect the normal work. Figure 2 In (the following components are all existing mature industrial products), the resistance values ​​of resistors R1, R2, and R3 are 100Ω, 4.7M, and 470K respectively; the models of NPN transistors Q2 and Q1 are 9013; the model of relay K1 is AC220V; the SMS module E2 is a SMS alarm module of model GSM800, and the finished SMS alarm module has two power input terminals 1 and 2, and signal input ports 3-8. After each signal input port inputs a low-level signal, the finished SMS alarm module will send a SMS via the wireless mobile network. The SMS alarm module stores SMS messages. In this embodiment, the SMS message "someone steals electricity or there is a power outage" is stored. The SMS alarm module After a low-level signal is input to the signal input port 3 of the block, the SMS alarm module can send a SMS; the solar panel G1 is 12V, 10W; the battery G2 is a 12V / 20Ah lithium battery capacitor C1 is a 10μF / 25V electrolytic capacitor; the pyroelectric detection module E1 is a human infrared sensing module of model SR602, which has two power input terminals and a signal output terminal. When working, the signal output terminal outputs power when there is human activity information within the 70-degree fan-shaped range of the front end of the detection head, otherwise it does not output (with a distance adjustment knob, which is adjusted to about 2 meters in this embodiment); the reed switch GH is a normally closed contact end reed switch.
