Techniques for obtaining and processing utility consumption data (e.g., gas, water, electricity, etc.) of a utility network to determine if a violation has occurred with respect to a restriction schedule associated with a service site. By way of example, a number of utility restriction schedules associated with a number of service sites may be generated that indicate, for example, a type of restricted activity and / or event (e.g., irrigation), seasons and / or which days activity is allowed or not allowed, duration activity is allowed, and / or mitigation to take place if a violation is detected. A device (e.g., a smart utility meter, a router, etc.) may monitor utility consumption and detect a particular usage activity (e.g., irrigation) via data disaggregation. The device may compare the activity to the restriction schedule for that particular service site and perform automatic mitigation if a violation is detected.

A sensor device, such as a consumption meter, has an LTE modem, a processor system connected with the LTE modem, and a sensor system including at least one sensor configured to sense a physical parameter and generate an output to the processor system accordingly. The sensor device is configured to receive an activation time via the LTE network, where the activation time includes an absolute time and / or an indication of a particular LTE frame number. The processor system is configured to cooperate with the LTE modem to time synchronize to a current LTE frame number. This can be particularly accomplished by the processor system sending a signal on the electrical pin to the LTE modem, in response, the LTE modem outputs the current LTE frame number, and the processor system starts a timer while sending the signal on the electrical pin. Accordingly, by starting a timer at a known LTE frame number, the sensor device can accurately calculate to initiate a predetermined action in synchronization with the absolute time indicated in the received activation time and the specific LTE frame number time. The action may involve performing a measurement using a sensor in the sensor device in time synchronization with the received activation time. This provides high precision time synchronization for a set of sensor devices, allowing the set of sensor devices to perform measurements simultaneously. This enables group measurements that cannot be achieved by the time accuracy of the internal clocks of a group of sensor devices, and this time synchronization may be very important for certain applications, such as acoustic leak detection in a utility network.

The invention discloses a locality protection configuration method for network survivability, belongs to the technical field of urban public service network security, and aims to solve the technical problem that an existing network survivability protection strategy cannot well cope with dynamic and complex attacks / failures to make configuration adjustment. The method comprises the steps that the coupling network edge weight of a first node pair is obtained according to the sensitivity of two nodes in the first node pair to the cost / price change of each other, the degree of each node is counted according to the existing coupling network edge weight, and the number of newly added protection edges of the protection strategy each time is limited. Therefore, a protection edge most worthy of protection is selected according to the degree of each node, and the product of the degrees of the two nodes is used as a protection weight; every time a network attack / cascade fault occurs, a new protection edge is added on the basis of the last protection result according to the rule, and the network survivability protection strategy can have high real-time dynamic performance.
