Embodiment

For it is clear explanation the utility model in technical scheme, be given below preferred embodiment and with reference to accompanying drawing specifically It is bright.

Referring to Fig. 1, the anti-theft device for cable in embodiment, including：Pass through the main frame and slave of cable connection；

The main frame includes：

For controlling the first single-chip microcomputer of modules；

For providing the first power module of direct current；

The slave includes：

For controlling the second singlechip of modules；

For providing the second source module of direct current；

Using the main frame and slave of said structure, on each street lamp, each section, one master of installation may be selected Machine, multiple slaves, under slave normal operating conditions, alternating current is detected from cable, that is, show the electricity between current each street lamp Cable path is normal；In the case of occurring powering off, slave can't detect alternating current on cable, be come from if detected on cable The direct current signal of main frame, so as to confirm that current cable status belongs to power-off；Cut when there is cable, stolen situation, from Machine does not receive any signal from main frame from cable, determines that present cable is stolen.

In embodiment, the first single-chip microcomputer, second singlechip use model STM8 single-chip microcomputer.

In embodiment, the first power module, second source module use storage battery power supply, such as Ni-MH battery power supply.

In embodiment, transformer has also been separately added into main frame, slave, for adjusting the voltage of civil power, has been easy to relay The detection of device.

In embodiment, LORA communication modules, using radio communication, communicated with main frame/slave, pass through the feelings of communication Condition can monitor whether public lighting circuit breaks in real time.

Up agreement：Standard DL/T645-2007 multifunctional electric energy meter communication extension agreements.

For example, it is to be based on SEMTECH radio frequency integrated chips using the LSD4RF-2F717N20 wireless modules of LORA agreements SX127X radio-frequency module, is a high-performance wireless transceiver for Internet of Things, its LORA debud mode can greatly increase communication away from From can be widely applied to the short distance Internet of Things wireless communication field of various occasions.It has small volume, low in energy consumption, transmission distance The features such as from remote, strong antijamming capability, there can be a variety of antenna schemes to be available for matching according to practical situations.

In embodiment, increasing the control circuit of discharge and recharge from end, as shown in Figure 2 to 4；Due to belonging to existing skill Art, repeat no more.

In embodiment, the circuit composition of relay is as follows：

Second relay, include Fig. 5~Fig. 7 three parts, referring to Fig. 5, detect alternating voltage, currently there are 220V power supplys When, transformer has output voltage, by judging CHK_USER1 level it is known that whether being 220V power supplies, circuit structure is such as Shown in Fig. 5.

Referring to Fig. 6, if 220V power supplies were currently not, that is, battery powered, relay will be switched to detection direct current Signal, the power supply 5.6V exported by transformer is come control relay, and during without 5.6V power supplys, relay is switched to detection direct current Signal, when having 5.6V, it will disconnect.

Referring to Fig. 7, direct current signal is detected, by judging CHK_USER2 level, will know that the outside feelings without forceful electric power Condition whether DC voltage.Also it is due to the stolen caused power-off of cable so that it is determined that being that cable has a power failure.

First relay, relay are used for controlling output direct current signal, by detecting CHK_USER1 level, detect road Whether lamp driver has electricity, and if electricity, relay disconnects, and does not export direct current signal；If without electricity, dc source is exported 27V, circuit structure diagram is as depicted in figure 8.

Second source module, the transformer DB-2-03FG used output AC power source all the way (9 pin and 10 pin) MBPW- A1 and MBPW-A2, become DC voltage 9VMB after being exported by rectifier bridge, be then depressured by DC-DC chips LM22673-ADJ For 5.6V, LM22673-ADJ 7 pin are input power 9VMB, and 8 pin are that out-put supply 5.6V, 5.6V become 5V by diode, Then it is 3.3V that 5V is depressured by DC-DC chips MP2451DT again, and MP2451DT 5 pin are input power 5V, and 6 pin are output electricity Source 3.3V, 3.3V are mainly used in main system and LORA module for power supply, and 5.6V is used as charge power supply and is supplied to 3.3V input electricity Source, circuit structure are as shown in Figure 9：

First power module, transformer DB-2-03FG two-way export, all the way output AC power source MBPW-A1 and MBPW- A2 (9 pin and 10 pin), becomes dc source 9VMB after being exported by rectifier bridge, then dropped by DC-DC chips LM22673-ADJ Press as 5V, LM22673-ADJ 7 pin are input power 9VMB, and 8 pin are out-put supply 5V, 5V and then pass through DC-DC chips again MP2451DT decompressions are 3.3V, and MP2451DT 5 pin are input power 5V, and 6 pin are out-put supply 3.3V, and 3.3V is mainly used in System and LORA module for power supply, 5V are used as charge power supply and are supplied to 3.3V input power, another way output AC voltage CRPW-A1 and CRPW-A2 (6 pin and 7 pin), becomes DC voltage 17V~75V, for exporting direct current after being exported by rectifier bridge Power supply 27V, the institute of circuit structure diagram such as 10.

Above-mentioned two power module, in addition to using transformer by mains-supplied, it is also respectively connected with Fig. 2~Fig. 4's The circuit and battery of discharge and recharge.For when having a power failure, powering off, using battery to be powered for main frame, slave, detecting circuit It is whether unobstructed, determine whether that cable occur is stolen.

For the part illustrated in each embodiment of the utility model, it is all the spirit and principles of the utility model it It is interior, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
