The police vehicle-mounted shielding system is mainly used for the police to deal with sudden mass incidents, control public opinion, arrest criminal suspects, prevent remote control bombs, communication control and the security of VIP personnel.
Then the following describes the operation sequence of the police car shielding system
First, park the police jammer at the mission site, turn on the switch of the power take-off generator, and then increase the engine speed to 2500 rpm, so that the power take-off generator can basically meet the power supply required by the equipment, which can last for a long time. Time stable output of 200V AC.
Second, operate the antenna lift controller to raise the roof antenna platform until the antenna is perpendicular to the ground. This approach is to maximize the effect of the police vehicle shielding system in the police jamming car in transmitting jamming signals.
Third, open the trunk of the police signal jammer car, turn on the power protector (air switch or leakage protection), and then turn on the power switch of the police car shielding system.
Fourth, turn on all the switches of the radio frequency module of the police car shielding system, close the trunk, and then go to the co-pilot position to turn on all the buttons on the wire control switch of the police jamming car. The radio frequency module of the police jamming car, There is an interference signal output.
Next, I will introduce the operation sequence of turning off the police jamming car.
First, turn off all the buttons of the wire-controlled switch, then turn off the switch of the radio frequency module, then turn off the power switch of the main unit of the police shielding system, turn off the power protector, reduce the engine speed of the police interference car, operate the antenna upgrade controller, and put the antenna The lodging mechanism is reduced to the minimum, and finally the power generator switch of the police jamming vehicle can be turned off.
If the police jamming vehicle needs to be used on the move, then before the vehicle leaves, the power protector of the main unit of the police vehicle shielding system, the power switch of the equipment and all the switches of the radio frequency module should be turned on. In this way, when the vehicle is running, it is only necessary to turn on the power take-off generator switch, then raise the antenna, and finally turn on the power output of all modules by controlling the wire-controlled switch. When closing, you need to turn off all switches on the wire-controlled switch first, then lower the antenna, and finally turn off the power take-off generator.
