Below in conjunction with accompanying drawing this invention is described in detail

Protection bunker as shown in Figure 1, its warehouse part 1 comprises left, right, front and rear, the upper and lower end, has protection ²⁴¹The ability of the neutron irradiation of Am-Be neutron source, the main material of its composition are boracic paraffin and carbon steel; The manual hinged door of door 4 is equipped with lock 5 and locknut 6 on the door, so that guarantee in the active source transportation not can be because of the top ripple damages door lock, even door is opened.Car 2 base plates in source are provided with pin 9, in order to the source car being fixed on warehouse 1 bottom, and can arbitrarily not skid off outside the warehouse along guide rail 3 in transit.Source car 2 has 3 wagon boxes, places a canned 740GBq respectively ²⁴¹Am-Be neutron source, a 54GBq ¹³⁷Cs source and a 18.5GBq ²⁴¹Am-Be scale neutron source.Interior guide rail 3 is directly installed on the protective layer plane, the end of warehouse 1, after vehicle-mounted active source protection bunker is transported to the destination, opens door, extracts source car pin, and the source car is gone up external guide rail after skidding off along interior guide rail 3, safety, convenient.

In the multi-functional warning antitheft security system block diagram shown in Figure 2, ray detector unit 7, dosage monitoring unit 8 and dosage indicator current table 10 and dosage alarm buzzer 11 are formed the dosage maintenance device, wherein, the electric functional block diagram of ray detector unit 7 is shown in Fig. 3 a: to the semiconductor detector J of gamma radiation sensitivity ₁, by high tension supply J ₄Provide+the 400V power supply, the gamma intensity of active source on the detection source car, the impulse singla that output amplitude is directly proportional with gamma intensity is through high-voltage capacitance C ₁Be coupled to pulse amplifier J ₂Input end is with J ₁The hundreds of millivolt impulse singla of output is enlarged into 8V, and this impulse singla is through J ₃Be input to the cathode follower CK of dosage monitoring unit 8 (shown in Fig. 3 b) behind the push-pull output circuit power gain ₁After doing the impedance conversion, incoming frequency-voltage conversion circuit CK ₂, transferring impulse singla to voltage signal output, this voltage signal-road is through voltage-current conversion circuit CK ₅, the voltage signal of 0-5V become the current signal of 0-300 μ A after, received current table 10 demonstrates the dosage size; Another road input voltage comparator C K ₃, with itself and pre-set threshold value CK ₄Compare; When greater than setting value, voltage comparator CK ₃Output signal is to dosage alarm buzzer 11, and warning pipes.

Under " normally " situation, promptly under the active source situation that all on your marks on the car of source, regulating voltage-current conversion circuit CK ₅Resistance value, the pointer indication that makes amperemeter/ammtr 10 is at the dial plate midway location, after active source is diverted, then pointer will be presented at the reference position of dial plate, in case taking place, active source leaks, or the unsafe condition do not built of carrying shield, then detector will detect the γ radiation stronger than normal circumstances, amperemeter/ammtr 10 pointers will raise, and depart from midway location, promptly surpass " normally " value (CK ₄The threshold value that sets), thus (buzzer phone 11 sound) prompting staff that reports to the police note.

The semiconductor probe of X-ray detection X unit 7 and electronic circuit are placed in the little iron sheet casket together, and (as Fig. 1 7) place near the source car in the bunker warehouse.The electronics circuit of dosage monitoring unit 8 and dosage test indicator 10, dosage warning (buzzer phone) 11 are installed on the vehicle drive indoor controller or panel.

One tunnel contact K of contact switch among Fig. 2 (travel switch) 12 ₁With annunciator 13, form wired acoustic-optic alarm of multi-functional warning antitheft security system with alert.Contact switch 12 is installed on the doorframe of bunker warehouse 1, contact K ₁Link with annunciator 13 with the police on warehouse 1 top.The key lock switch that is provided with on the controller panel of operator's compartment is opened, and promptly the antitheft security system power connection makes it in running order or the title state of alert, at this moment, if there is the people that door 4 is opened, contact K ₁Close, alert send police whistle sound immediately, red lamp flass simultaneously, the late into the night, but 500 meters of police whistle sound teletransmissions with annunciator 13 energized.

Among Fig. 2, another contact, road K of contact switch 12 ₂, vibration sensor 14, wireless calling alarm control unit 15, alarming horn 16, antenna 17 and wireless receiver 18 form the wireless calling warning device of antitheft security systems, the electrical schematic diagram of wireless calling alarm control unit 15 wherein as shown in Figure 4, control main board is a cpu chip micro controller system PIC16C73, it has 5 binary pair P1.0, P1.1, P1.2, P1.3, P1.4 receives two contact K of contact switch 12 respectively ₁And K ₂(enabling signal of bunker), the signal of vibroswitch 14 (dividing strong, weak two class), and check warning whether normal two check valve A and B; 2 power drive output signal end P0.1 and P0.2, loudspeaker 16 taking alarm and light-emitting diode D respectively ₁Control main board also has a serial signal output part TXD, connects the modulation circuit of wireless signal transmission plate, and serial signal is modulated, the signal that modulates, enter mixer circuit and local oscillation signal mixing after, input amplifying circuit, after amplifying, to go out by antenna transmission, wireless receiver just can receive.This system adopts KEELOQ frame hopping coding.Press the wireless calling alarm control unit UN6609 interconnecting wiring diagram of Fig. 5, connect the line, when system is on the alert, if there is the people to open the source door, contact switch 12-K ₂Connect, after radio alarming control unit 15 is received signal, singlechip CPU is judged has the people illegally to open the door, loudspeaker 16 send ear-piercing cry, simultaneously, the TXD of control unit mainboard sends serial signal, and this signal sends wireless signal from antenna after the wireless transmission plate is handled, wireless receiver sends the continuous cry of BI, BI after receiving signal, and shows that on LCDs door is opened.Simultaneously, when the people attempted to open the bunker door, the vibration of generation made the vibration sensor that is installed on the gate produce output, signal is received in alarm control unit 15, send wireless signal simultaneously, receptor just sends BI, BI cry, and shows the vibrations icon on LCDs.

The 12V power supply of the multi-functional warning antitheft security system of vehicle-mounted radioactivity protection bunker is supplied with and can be provided by circuit shown in Figure 6, and automobile storage battery is 24 volts, and mouth is 12V; Mouth is provided with a chargeable battery, at ordinary times, by circuit shown in Figure 6, by the 24V of automobile storage battery rechargeable battery is charged, and stops charging automatically to 12V.This battery for just in case automobile storage battery 24V is out of order or when stolen emergency standby.
