Electronic system with a multiple access protocol and method of multiple access
First Claim
1. An electronic system comprising at least one first unit (200) for a first spatial region, at least one second unit (500) for a second spatial region, a network (1) in which each of the at least one first unit and the at least one second unit are connected with each other, the first spatial region and the second spatial region being separate from each other, and a multiple access protocol for access of each of the at least one first unit and the at least one second unit to the network, wherein at least one of said at least one first unit and at least one of said at least one second unit are assigned to a single concurrent time slot.

Abstract
The electronic system, especially a security system, includes a number of different units that access a network according to a multiple access protocol, which is designed to minimize collisions between frames while reducing bandwidth requirements. The units may monitor different spatial regions according to several different criteria. Respective units that monitor according to correspondingly different criteria in a given spatial region may be assembled into one group and units that monitor different spatial regions but according to the same criterion may be assembled into another group. Each of the units of the one group are provided access to the network in one concurrent time slot, while the units of the other group are provided access to the network in a different concurrent time slot.

- 1. An electronic system comprising at least one first unit (200) for a first spatial region, at least one second unit (500) for a second spatial region, a network (1) in which each of the at least one first unit and the at least one second unit are connected with each other, the first spatial region and the second spatial region being separate from each other, and a multiple access protocol for access of each of the at least one first unit and the at least one second unit to the network, wherein at least one of said at least one first unit and at least one of said at least one second unit are assigned to a single concurrent time slot.
- 4. An electronic system comprising at least one first unit (300) for monitoring a spatial region for the presence of a first criterion, at least one second unit (400) for monitoring said spatial region for the presence of a second criterion, a network (1) in which the at least one first unit and the at least one second unit are connected with each other, and a multiple access protocol for access of the at least one first unit and that at least one second unit to the network, wherein at least one of said at one first unit and at least one of said at least one second unit are assigned to a single concurrent time slot.
- 10. A method for accessing at least one first unit and at least one second unit to a network, wherein said at least one first unit includes means for monitoring a first spatial region and at least one second unit includes means for monitoring a second spatial region, wherein the first spatial region and the second spatial region are separate from each other, wherein the accessing takes place by means of a multiple access protocol, and wherein at least one of said at least one first unit and at least one of said at least one second unit are assigned to a single concurrent time slot.
- 13. A method for accessing at least one first unit for monitoring a spatial region according to a first criterion and at least one second unit for monitoring the spatial region according to a second criterion in a network connecting said at least one first unit and said at least one second unit, wherein the accessing takes place by means of a multiple access protocol, and wherein at least one of said at least one first unit and at least one of said at least one second unit are assigned to a single concurrent time slot.
