REMOTE SECURITY SYSTEM

The Remote Security System is an electronic system that avoids the danger of electrocution in high voltage electrical networks. It is characterized by each switch having a lock with a security key, which is locked / unlocked by a central unit (fig. 1), and by having a remote unit (fig.

2) at each point of the electrical network to be repaired. The remote unit has a set of work cards (17) that are distributed to workers, who are returned after repairs. When the security key is locked on the central unit, the work cards (17) are unlocked on the remote unit, and vice versa. The security key is never unlocked at the same time as the work cards. Each central unit communicates with each of the remote units via modems, or transceiver radios, or mobile phones.

The Remote Safety gyate creates such a safety environment for workers who carry out repairs and high-voltage electrical networks, as well as equipment for industrial installations, such as the system. Safety Remote is eupeca.altnente conceiuicio to be used in high voltage electrical networks, overriding the description uai having as an example <âe application a high voltage electrical network ©: nsã.o.

Nowadays, when there is a. n.eceseld.a.de to repair a malfunction of a high voltage electrical network, the person responsible for security disconnects or disconnects the electrical, telephone, teletówel.

When tereunant repair works, the head of the repair team calls back. for the security officer to say that · tersij.liaram. and unlock the switch and turn on the electric current. Due to the crazy distance between the network point that needs to be repaired and the switch that turns it off, the following safety problems can arise:

• Before starting to carry out repairs on the electric network, the 1.fenders may have doubts as to whether the electric current is switched off or not.

• The electric current can be connected i * idevi..dament.e while treating them.! Todorea is carrying out repairs, • The moment the person in charge of safety goes, turn on the electric current., He may have doubts if workers do not. terrainarani the repairs or not.

Generally, a malfunction in a high voltage electrical network occurs only at one point, and there is usually only one switch for the So, in this case, parti.cula.r. the person most responsible for security must assign a central unit to the switch to be turned off and a king unit to the point of. electrically powered unia 1 · ,. · - co-acccations (communication channel) between the two units, the safety officer must transfer a connector (fig. 3} (12) from the central unit (fig. 4) (20) to the central unit, brown 1 connected to the remote unit (obtains 1 connector), Thus, the central unit knows cc® that the removal agent must communicate, a video that the microcoxoxererator of the present central unit knows qxial is the ccciiao of the missing gas. On the other hand, the remote unit knows with which central unit this remote unit knows which is the code of the connector that Ine In fig. '7 is required, in certain communications, a single hl ratio.

In order to repair a point in an electrical network, I will be responsible for, safety should turn off the switch and reset it with the respective traffic device (fig 1, 2). Stop. · - (fig. D 'off position ifxg. 2) (1), and turn a. security key (6? so that the switch is locked. Afterwards, the security officer removes the security key (lock oj (5) and inserts it in the housing slot (fig. 3) (9) central unit, the on.de is blocked due to the action of the blocking slide (fig 5) (A). Meanwhile, the safety switch (31) activates the limit switch (2'7), which sends a signal to the radio sensor indicating that the security key is present, so the microcontroller instructs the security key code reader to read the code. At this point, the code is shown on the display (fig. 3) (8 ) in order for the security officer to verify that the code is & expected. If the security key code is as expected, the security officer is next to the trarismiosis button (11). At this point, the transmission button sends a signal to the my controller, which in turn deactivates the unlock button (10) of the cie key Even if the unlock button is pressed, the security key remains locked. At the same time, rnicrocorit.rola.dor sends reia. message with the security key code to the remote unit via the communication unit. The code of the security key sent to the remote unit indicates that the switch associated with the unit is off and locked.

When the remote unit is received from the central realm with the security key code, the microcontroller activates the unlock button (13) on the work cards. Then the head of the repair screen checks the display (15) whether the security key code is expected. If so. then he presses the unlock button (18) of the work cards, which activates the electromagnet (fig 6) (35) that pulls the lock bar (32), unlocking all the cards. · - '4 ) (18) is pressed, each worker takes a card from the work (17) there.

• where the connector will be transferred to;

• The «orne and / or the geographic coordinates of the point of the electricity network in need of repair;

With this type of information, each remote unit compares its own code with the code contained in each connector. It also compares the security key code received from each central unit with the code contained in each of the connectors. If there is a code that does not match the codes found on the scanners, the work cards are not unlocked and an error message is displayed on the display.
