Abstract

Electromechanical closing device for manhole covers, entrances and technological containers, with an electronic code system for the opening. The closing device is activated by a suitable key which, besides transmitting the opening codes, also gives the necessary power supply for its functioning. Moreover, the device may be remotely controlled by a supervision system.

Description

Electromechanical closing device for manhole covers, entrances and technological containers, with an electronic code system for the opening.
**********
There exist products which have assumed universal characteristcs with the passing time: among them, there is the typical manhole cover or crawl space which has used been in all streets in all the cities in the world for a long time.
This product is used as an access to conduits in different fields, such as the access to cable ducts, sewers, rainwater ducts and tunnels in which there is public utility machinery or equipment, isolating gates for portions of sewerage systems, watertight gates, control units for the distribution system of gas, electric power and data transmission, etc.
Due to their widespread distribution, these accesses are increasingly often used for illegal activities which range from the interception of communication lines to use for terroristic purposes. Because of this, it is necessary to efficiently protect the accesses, so that they can be used exclusively by authorized people.
In order to control these accesses, it is possible to use a manhole cover or a crawl space provided with an electronic system which enables or disables the opening.
The authorisation for the opening is effected by a specific key which sends a password to the electronic system; moreover, the manhole cover may be provided with sensors which detecte a non authorized opening and/or tampering, sending an alarm signal to the control station.
For the control of the territory, underground passages and even passages above the ground can be protected by this system by using controlled and hierarchical accesses, thus increasing the security in the civil, military and paramilitary sectors. For example, it is possible to protect the telephonic transposition cabinets which can be found in every corner of the roads and, therefore, exposed to the risk of vandalism, tampering, espionage, etc.
Figure 1 schematizes, by functional blocks, the different components of the system: it is essentialy composed of a key (A) necessary for the opening of a wing, a control unit (B) integrated with the wing which locks or unlocks the latch and an optional connection module, to be used when we want to remotely supervise the system itself.
The key (A) contains a microcontroller (AC) which directs all the operations of the device, in particular it receives the data inserted by the operator by means of a keyboard (AT) and a possible identification device (AR) (a magnetic strip reader, a bar code reader, a RFID reader or others) and visualizes possible messages on the display (AD). Furthermore, the key (A) is provided with a permanent memory (AM) suitable for containing a register of the operations carried out and the configuration data received from the communication interface (All), as well as a second communication interface (AI2) which allows the dialogue with the unit control (B), a battery (AB) which, in addition to feeding the device, supplies the necessary power for the functioning of the unit control (B) and, a possible clock (AO) in order to enable the time data to be associated to the data concerning the executed operations. The key (A) commnicates with the unit control (B) through an electromechanical soupler (AA); such a coupler has both the aim to put the two devices (A) and (B) in communication with each other, and to transmit the manual mechanical movement necessary to operate the opening latch of the wing.
The control unit (B) is integrated with the wing and has the purpose of locking or unlocking the latch of the wing itself. The control unit (B) is provided with a microcontroller (BC) which directs all the functions; in particular, by the communication interface (BIl), it communicates with the key (A) through the electromechanical coupler (AA).
Furthemore, the control unit (B) is provided with a permanent memory (BM) suitable for containing the configuration data and a register of the operations carried out, one or more sensors (BD) which detect possibile non-authorized openings of the wing and possible tamperings, a locking/unlocking device of the latch (BS), a second communication interface (BI2) which enables the dialogue with the possible connection module (C), an administrator unit (BA) for the feeding supply which can receive power both from the key (A) and the possibile connection module (C), and a possible clock (BO) which enables the time data to be associated to the data concerning the executed operations. The connection module C is not essential for the functioning of the system, but it is very useful when we want to remotely supervise a certain number of devices. It is composed of an interface converter (CC) which dialogues both with the control unit (B) and the remote supervision system to which it is connected by means of the communication network (RC). Moreover, it is equipped with a power supplier (CA) with a buffer battery, connected to the electric network (RE) which ensures power both to the interface converter (CC) and to the control unit (B) to which it is conneceted. If there is the connection module, the control unit (B) is constantly fed and, then, it is also able to carry out all the anti-tampering control functions; on the other hand, the control unit (B) is active only when the key (A) is inserted for opening or closing the wing and, then, it only carries out the functions of an electronic lock. The following figures show a possible application of the device for a manhole cover or road crawl passage.
Figure 2 shows a construction of the key (A) wherein there are depicted the display (AD), the keyboard (AT), the identification device (AR), the electromechanical coupler (AA) composed of the square tang (AQ) and the tabs (AAl and AA2). In this specific construction, the transmission of the power and the communication signals between the key (A) and the control unit (B) occurs by means of the contacts placed at the ends of the tabs (AAl and AA2), but, it can be achieved in different ways: for example, the power transmission may occur by an elctromagnetic coupling, while the communication signals may be transferred optically or by radiofrequency. Figure 3 shows a section of a construction of a manhole cover equipped with a control unit (B) and the connection module (C).
The manhole cover is provided with a suitably shaped hole (F) wherein the key (A) has to be inserted. The hole (F) is closed by the shutter (S) which is controlled by the locking/unlocking device of the latch (BS) (which has also the aim of locking the rotor R and avoiding that its movement by hand) and, therefore, the key (A) cannot continue its run; however, the key may rotate counter-clockwise since its tabs (AAl and AA2) (which are part of the electromechanical coupling AA) may slide along the groove (El) and the corresponding groove (E2).
Once the key (A) has reached the end of the run, it establishes the electrical connection with the control unit (B) through the contacts placed at the ends of the tabs (AAl and AA2) and the corresponding contacts (Gl and G2).
The control unit (B) is thus fed and it is put in communication with the key (A) thus requiring personal identification and/or a password to the operator; if the operator is authorized and/or the password is correct, the control unit (B) moves back the shutter (S) by means of a worm screw (V) thus clearing the hole (F).
Therefore, the key (A) may be brought back to the initial position and then, inserted further inside the manhole cover until its square tang (AQ) is inserted in the seat (Q) made in the rotor (R). Now, the operator may manually move the latches (Hl and H2) connected to the rotor (R) simply by rotating the key clockwise.
In figure 4, the situation subsequent to the opening of the latches (Hl and H2) is depicted and the manhole cover may be lifted until it reaches the position illustrated in figure 5. The plate (P) has a double function acting as a support and a guide for the rotor (R) and the latches (Hl and H2), and protecting the manhole cover and its equipment from possible attacks made from inside.
The closing operaton is made by carrying out the previous operations in the inverse order. If there is the connection module (C), the control unit (B) may be constantly fed and continuously detects any attempt of tampering; furthermore, it can be constantly connected with the supervision system for carrying out monitorings, planning of accesses and notification of anomalies.
