[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0019] The present invention is a multi-point call control system. The front stage of the system is externally connected with a distribution controller, and the distribution controller is connected with a remote communication module on the exterior. The rear stage of the system is externally connected with a main controller, and the main controller is connected with an internal communication module. The remote communication module and the internal communication module can realize information interaction. The multi-point call control system is characterized in that it includes a plurality of activation trigger units in the front stage, each activation trigger unit is distributed at different positions in the arranged scenario, each activation trigger unit is externally connected with its corresponding call device respectively, the multi-point call control system further includes a total connection unit, and the total connection unit includes a plurality of prompt processing modules, and the number of the prompt processing modules is not less than the number of the arranged activation trigger units.
[0020] This application is divided into a front stage and a rear stage of the system. The rear stage of the system is the total connection unit, and the front stage of the system is multiple start trigger units. Each remote communication module is distributed in different areas according to the on-site situation and can adopt a similar evenly distributed manner, etc. Each start trigger unit is correspondingly provided with a call device. The call device includes a controller, a microphone, and a transmission unit. The principle of the call device is similar to that of a walkie-talkie or a telephone and can be implemented by various schemes. The start trigger unit is connected to the distributed controller inside the call device. The front-stage circuit of the start trigger unit can be realized by means of a switch, etc. When someone near the start trigger unit discovers an abnormality, the call device in the rear stage can be started by powering on the start trigger unit. After the call device receives the signal, it sends the signal to the internal communication module of the main console through the set remote communication module. When the main console receives the signal, it then sends the signal to the rear stage of the system of this application through the main controller. The rear stage of the system is multiple parallel prompt processing modules, and the rear stage of each prompt processing module is externally connected to a prompt system.
[0021] Applying this solution, when patrol personnel or other personnel in the park encounter an emergency, they can all notify the duty personnel in the duty room by finding the nearest start trigger unit. In the total connection unit, each prompt processing module corresponds to the corresponding start trigger unit. Through the change of the prompt processing module, it is easy to know where a danger has occurred.
[0022] As shown in the attached Figure 1 As shown in the figure, the start trigger unit includes an optocoupler U1. The positive pole of the input side of the optocoupler U1 is connected to the first voltage source. The negative pole of the input side of the optocoupler U1 passes through a resistor R1 as the signal input terminal Vin1. The positive pole of the output side of the optocoupler U1 is connected to the second voltage source through a resistor R2. The negative pole of the output side of the optocoupler U1 is grounded. The positive pole of the output side of the optocoupler U1 passes through a resistor R3 as the output terminal Vout1 of the start trigger unit. At the series connection point of the optocoupler U1 and the resistor R1, another capacitor C1 is grounded, and the positive pole of the capacitor C1 is connected to the optocoupler U1.
[0023] Since there are multiple start trigger units and the schematic diagrams of each start trigger unit are the same, taking the first one as an example, first, when the positive pole of the optocoupler receives a signal Vin1 with a high potential, there is no potential difference between the two poles of the input side of the optocoupler U1, so the output side of the optocoupler U1 is cut off. At this time, the start trigger unit outputs a high potential to start the alarm of the rear-stage module; when the positive pole of the optocoupler U1 receives a signal Vin1 with a low potential, the output side of the optocoupler U1 is turned on, then Vout1 is short-circuited, and the alarm of the rear stage will not be triggered.
[0024] In the total connection unit at the rear stage of the system, each prompt processing module is connected in parallel. Each prompt processing module includes an isolation module and a switch circuit. The input end of the isolation module is externally connected to the main controller, the output end of the isolation module is connected to the controlled end of the switch circuit, and the switch side of the switch circuit is externally connected to the prompt device. A switch can be connected to the front stage of the start trigger unit, and this switch is connected in series between an external voltage source and the start trigger unit.
[0025] As shown in the attached Figure 2 of the specification, the isolation module includes an optocoupler U5. The positive electrode on the input side of the optocoupler U5 serves as the input end of the isolation module, the negative electrode on the input side of the optocoupler U5 is grounded, the positive electrode on the output side of the optocoupler U5 is connected to the third voltage source through a resistor R5, the negative electrode on the output side of the optocoupler U5 is grounded, and the positive electrode on the output side of the optocoupler U5 serves as the output end of the isolation module. The switch circuit includes a switching transistor Q1 and a relay K1. The base of the switching transistor Q1 passes through a resistor R14 as the input end of the switch circuit. The collector and emitter of the switching transistor are connected in series between the third voltage source and the coil side of the relay K1. The other side of the coil side of the relay K1 is grounded, and the switch side of the relay K1 serves as the switch side of the switch circuit. The switch circuit also includes a diode D2. The cathode of the diode D2 points to the high potential side, and the anode of the diode D2 is grounded.
[0026] Among them, the optocoupler U5 plays an isolation role. When a certain start trigger unit is triggered, through the pager, the start signal is first transmitted to the externally connected internal communication module. After the internal communication module adjusts and processes the signal, it is sent to the total connection unit through the externally connected main controller. The input voltage of the prompt processing module at the corresponding position in the summary unit changes. When Figure 2 V1 inputs a high potential, the optocoupler U5 is turned on, the base potential of the triode Q1 drops, the triode Q1 is short-circuited, and the relay K1 is a normally closed relay, so there is no current switch closure for the relay K1; on the contrary, the relay K1 is turned on.
[0027] The function of the starting diode D1 is to discharge current to prevent the coil current from breaking down the triode. The protected solution of this application is the start trigger units distributed in multiple places at the front stage of the system and the summary unit at the rear stage of the system. Other modules are externally connected and can be processed using existing bases.
[0028] Those skilled in the art can clearly understand that, for the convenience and brevity of description, only the above division of each functional unit and module is used as an example. In actual applications, the above functions can be allocated to different functional units and modules according to needs, that is, the internal structure of the device can be divided into different functional units or modules to complete all or part of the functions described above. Each functional unit and module in the embodiment can be integrated into a processing unit, or each unit can exist physically alone, or two or more units can be integrated into one unit. The above integrated unit can be implemented in the form of hardware or in the form of a software functional unit. In addition, the specific names of each functional unit and module are only for the convenience of mutual distinction and do not limit the protection scope of the present application. The specific working processes of the units and modules in the above system can refer to the corresponding processes in the foregoing method embodiments and will not be elaborated herein.
[0029] Applying the present application, it is arranged at various potential hazard or key positions in the park. When someone discovers an emergency, they can notify the duty room in a timely manner, not simply relying on the on-duty personnel, which is equivalent to making up for the monitoring vacuum period during which the on-duty personnel may relax their vigilance through convenient calling devices.
[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
